As observed in several of the posts, there's really no need for struct file to exist in the xattr code. It was really only passed around due to the f_op->readdir() and a_ops->{prepare,commit}_write prototypes requiring it. reiserfs_prepare_write() and reiserfs_commit_write() don't actually use the struct file passed to it, and the xattr code uses a private version of reiserfs_readdir() to enumerate the xattr directories.

This patch fixes the problem by saving and disabling i2c-omap interrupt before turning off the clocks. Also disable functional clock before the interface clock as suggested by Paul Walmsley. Patch also renames enable/disable_clocks functions to unidle/idle functions. Note that the driver is currently not taking advantage of the idle interrupts. To use the idle interrupts, driver would have to enable interface clock based on the idle interrupt and dev->idle flag. This patch has been tested in linux-omap tree with various omaps.

This creates a race between the ndisc and pneigh_delete - after the pneigh is returned to the caller, the nd_tbl.lock is dropped and the deleting procedure may proceed. One of the fixes would be to add a reference counting, but this problem exists for ndisc only. Besides such a patch would be too big for -rc4. So I propose to introduce a __pneigh_lookup() which is supposed to be called with the lock held and use it in ndisc code to check the flags on alive pneigh entry. Changes from v2: As David noticed, Exported the __pneigh_lookup() to ipv6 module. The checkpatch generates a warning on it, since the EXPORT_SYMBOL does not follow the symbol itself, but in this file all the exports come at the end, so I decided no to break this harmony. Changes from v1: Fixed comments from YOSHIFUJI - indentation of prototype in header and the pndisc_check_router() name - and a compilation fix, pointed by Daniel - the is_routed was (falsely) considered as uninitialized by gcc.

Miller" Date: Mon, 24 Mar 2008 20:06:24 -0700 Subject: [SPARC64]: Make save_stack_trace() more efficient. Doing a 'flushw' every stack trace capture creates so much overhead that it makes lockdep next to unusable. We only care about the frame pointer chain and the function caller program counters, so flush those by hand to the stack frame. This is significantly more efficient than a 'flushw' because: 1) We only save 16 bytes per active register window to the stack. 2) This doesn't push the entire register window context of the current call chain out of the cpu, forcing register window fill traps as we return back down. Note that we can't use 'restore' and 'save' instructions to move around the register windows because that wouldn't work on Niagara processors. They optimize 'save' into a new register window by simply clearing out the registers instead of pulling them in from the on-chip register window backing store. Based upon a report by Tom Callaway.

Usually, this does not matter since most of the tss contents is within the default length of 0x67. However, if a process is using ioperm() to grant itself I/O port permissions, an additional bitmap within the tss, but outside the default length is consulted. The effect is that the process will receive a SIGSEGV instead of transparently accessing the port. Fix by restoring the tss length. Note that i386 had this working already. Closes bugzilla 10246.

The BIOS reports the interrupt routing incorrectly. I recently added a quirk to work around this, and this patch fixes a typo in the quirk. We pad every ACPI pathname component to four characters, so ".ISA." will never match anything. We need ".ISA_." instead. Thank you Johann-Nikolaus Andreae for patiently testing this patch.

If we get interrupt, there's sufficient reason to schedule napi. o replenish rx ring more often, remove self-imposed threshold rcv_free that prevents posting rx desc to card. This improves performance in low memory.

This fixes a race caused by rx softirq preemption on realtime kernels.

This is technically a false positive, since the uses in sge.c are only in the initialization and cleanup paths and cannot overlap with any use in interrupt context. The best fix is probably just to use spin_lock_irq() with reg_lock in sge.c. Even though it's not strictly required for correctness, it avoids triggering lockdep and the extra overhead of disabling interrupts is not important at all in the initialization and cleanup slow paths.

This inaccuracy is due to interrupts being handled before we account for C-state exit. Do not mark TIME_VALID for CO poll state. Mark C1 time as valid only with the MWAIT (CSTATE_FFH) entry method. This makes governors use the timing information only when it is correct and eliminates any wrong policy decisions that may result from invalid timing information.

So a timer can be delayed for quite a long time. This triggered a false positive in the clocksource watchdog code. To avoid this we need to wake up the idle CPU and enforce the reevaluation of the timer wheel for the next timer event. Add a function, which checks a given CPU for idle state, marks the idle task with NEED_RESCHED and sends a reschedule IPI to notify the other CPU of the change in the timer wheel. Call this function from add_timer_on().

Fix it bu going to a proper label. Found after net namespace's lo refused to unregister :) Many thanks to Den for valuable help during debugging.

See http://lkml.org/lkml/2008/2/19/405 http://bugzilla.kernel.org/show_bug.cgi?id=9961 I have a fix for the ThinkPad docking Oops but if the issue being discussed here is caused by the transparent bridge sizing removal change I totally agree that it should be reverted." The transparent bridge sizing removal change was motivated by insufficient PCI memory resource for a transparent bridge window that was being created as a result of expansion ROM(s) being included in the transparent bridge sizing calculations. A later "PCI: Remove default PCI expansion ROM memory allocation" change ( re: http://lkml.org/lkml/2007/12/11/361 ) removes the expansion ROM(s) from the transparent bridge sizing calculations which actually resolves the original issue in a different manner. So, even if the "PCI: remove transparent bridge sizing" is not problematic it is no longer needed anyway."

This resulted in a kernel panic when the wrong context was used to build the RPC iovec page list. RDMA_READ is used to fetch RPC data from the client for NFS_WRITE requests. A scatter-gather is used to map the advertised client side buffer to the server-side iovec and associated page list. WR contexts are used to convey which scatter-gather entries are handled by each WR. When the write data is large, a single RPC may require multiple RDMA_READ requests so the contexts for a single RPC are chained together in a linked list. The last context in this list is marked with a bit RDMACTXT_F_LAST_CTXT so that when this WR completes, the CQ handler code can enqueue the RPC for processing. The code in rdma_read_xdr was setting this bit on the last two contexts on this list when the last read-list chunk spanned multiple pages. This caused the svc_rdma_recvfrom logic to incorrectly build the RPC and caused the kernel to crash because the second-to-last context doesn't contain the iovec page list. Modified the condition that sets this bit so that it correctly detects the last context for the RPC. Signed-off-by: Tom Tucker Tested-by: Roland Dreier Signed-off-by: J.

Recent changes in page attribute code made both ioremap()/ioremap_nocache() mappings as UC (instead of previous UC-). This breaks the graphics performance, as the effective memory type is UC instead of expected WC. The correct way to fix this is to add ioremap_wc() (which uses UC- in the absence of PAT kernel support and WC with PAT) and change all the fb drivers to use this new ioremap_wc() API. We can take this correct and longer route for post 2.6.25. For now, revert back to the UC- behavior for ioremap/ioremap_nocache.

This causes a crash as the packet doesn't actually have that many bytes for a second header. The IPv4 BEET output on the other hand is broken when it comes to handling an inner IPv6 header since it always assumes an inner IPv4 header. This patch fixes both by making sure that neither BEET output function touches the inner header at all. All access is now done through the protocol-independent cb structure. Two new attributes are added to make this work, the IP header length and the IPv4 option length. They're filled in by the inner mode's output function.

Unfortunately, the pending flag must be modified with a locked operation since it can be set by another CPU, and the unlocked form of this operation was causing the pending flag to get lost, allowing the processor to return to usermode with pending events and ultimately deadlock. The simple fix would be to make it a locked operation, but that's rather costly and unnecessary. The fix here is to split the mask-clearing and pending-testing into two instructions; the interrupt window between them is of no concern because either way pending or new events will be processed. This should fix lingering bugs in using direct vcpu structure access too.

Perhaps that means the device will not reach a sleep state and consumes more power then it should, but it is equally possible it simply needs some seconds longer to sleep.

The circumstances are that do_page_fault() calls do_dabr(), this clears the DABR (sets it to 0) and sets up the signal which will report to userspace that the DABR was hit. The do_signal() code will restore the DABR value on the way out to userspace. If we reschedule before calling do_signal(), __switch_to() will check the cached DABR value and compare it to the new thread's value, if they match we don't set the DABR in hardware. So if two threads have the same DABR value, and we schedule from one to the other after taking the interrupt for the first thread hitting the DABR, the second thread will run without the DABR set in hardware. The cleanest fix is to move the cache update into set_dabr(), that way we can't forget to do it.

In particular this means that if an application passes in IRD > 0 and ORD = 0 (which is a completely sane and valid thing to do for an app that expects only incoming RDMA read requests), then the hardware will end up programmed with IRD = 0 and the app will fail in a mysterious way.

It brings the usual flurry of fixes for false positives. It also brings a number of new checks. The most contentious change will likely be the checks for NR_CPUS as this throws some new warnings in kernel/sched.c. Of note: - all new quote tracking across lines - all new comment tracking - new more direct, less ambigious wording for some warnings - recommends mutexes and completions over semaphores - recommends strict_strto* over simple_strto* - report on direct use of NR_CPUS Andy Whitcroft (22): Version: 0.16 string quote tracking should cross line boundaries check spacing round -> correctly across newlines checks for linux/ against asm/ include files should be warnings standardise on 'required' and 'prohibited' take the first end of condition when parsing statements values: cope with unbalanced brackets preprocessor #elif is not a function preprocessor #if should not trigger trailing statement checks test: allow us to limit output to a single error recommend real mutexes over semaphores asm checks should mirror those for __asm__ warn on semaphores being used in place of completions trailing ; on control structure should ignore do {} while (); recommend strict_strtoX over simple_strtoX redo comment handling as a quote type use of NR_CPUS is normally wrong consistant spacing should only be about spaces if brace check suppression should only apply to the top-levels use tr/// to align spacing for operators move to using four parameter form of substr check and report modifications to include/asm Signed-off-by: Andy Whitcroft Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- scripts/checkpatch.pl | 463 ++++++++++++++++++++++++++++++-------------------- 1 file changed, 279 insertions(+), 184 deletions(-) diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index 2a7cef9726e4..58a94947d655 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -9,7 +9,7 @@ use strict;

This means that this quirk is unsafe and has to be removed.

If write requests need to be split into pieces, the code must not process them in parallel because the crypto context cannot be shared. So there can be parallel crypto operations on one part of the write, but only one write bio can be processed at a time. This is not optimal and the workqueue code needs to be optimized for parallel processing, but for now it solves the problem without affecting the performance of synchronous crypto operation (most of current dm-crypt users). http://bugzilla.kernel.org/show_bug.cgi?id=10242 http://bugzilla.kernel.org/show_bug.cgi?id=10207 Signed-off-by: Milan Broz Signed-off-by: Alasdair G Kergon Cc: "Rafael J.

The leak looks legit to me - this is the code : int driver_add_kobj(struct device_driver *drv, struct kobject *kobj, const char *fmt, ...) { va_list args; char *name; int ret; va_start(args, fmt); name = kvasprintf(GFP_KERNEL, fmt, args); ^^^^^^^^ This dynamically allocates space... va_end(args); if (!name) return -ENOMEM; return kobject_add(kobj, &drv->p->kobj, "%s", name); ^^^^^^^^ This neglects to free the space allocated } Inside kobject_add() a copy of 'name' will be made and used. As far as I can see, Coverity is correct in flagging this as a leak, but I'd like some configmation before the patch is applied. This should fix it.

It forces low level drivers to have a workaround to adjust scatter lists that the IOMMU builds. We are in the process of making all the IOMMUs respect the segment boundary limits to remove such work around in LLDs. SPARC64 IOMMUs were rewritten to use the IOMMU helper functions and the commit 89c94f2f70d093f59b55d3ea8042d13889169346 made the IOMMUs not allocate memory areas spanning the segment boundary limit. However, SPARC64 IOMMUs allocate memory areas first then try to merge them (while some IOMMUs walk through all the sg entries to see how they can be merged first and allocate memory areas). So SPARC64 IOMMUs also need the boundary limit checking when they try to merge sg entries. Signed-off-by: FUJITA Tomonori Signed-off-by: Andrew Morton Signed-off-by: David S.

A patch was submitted to bug: http://bugzilla.kernel.org/show_bug.cgi?id=4420 which simply truncated the "location", read whatever was in "location modulo addr_len", and returned that value. That avoids confusing the eeprom but seems like the wrong solution to me. Correct would be to not read beyond "1 << addr_len" address of the eeprom. I am submitting two changes to implement this: 1) tulip_read_eeprom will return zero (since we can't return -EINVAL) if this is attempted (defensive programming). 2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't iterate past addr_len bits and make sure the entire tp->eeprom[] array is cleared. I konw we don't strictly need both. I would prefer both in the tree since it documents the issue and provides a second "defense" from the bug from creeping back in.

One useful +technique is the creation of virtual files, in debugfs, /proc or elsewhere. +Virtual files can provide human-readable output that is easy to get at +without any special utility programs; they can also make life easier for +script writers. It is not surprising that the use of virtual files has +grown over the years. + +Creating those files correctly has always been a bit of a challenge, +however. It is not that hard to make a virtual file which returns a +string. But life gets trickier if the output is long - anything greater +than an application is likely to read in a single operation. Handling +multiple reads (and seeks) requires careful attention to the reader's +position within the virtual file - that position is, likely as not, in the +middle of a line of output. The kernel has traditionally had a number of +implementations that got this wrong. + +The 2.6 kernel contains a set of functions (implemented by Alexander Viro) +which are designed to make it easy for virtual file creators to get it +right. + +The seq_file interface is available via . There are +three aspects to seq_file: + + * An iterator interface which lets a virtual file implementation + step through the objects it is presenting. + + * Some utility functions for formatting objects for output without + needing to worry about things like output buffers. + + * A set of canned file_operations which implement most operations on + the virtual file. + +We'll look at the seq_file interface via an extremely simple example: a +loadable module which creates a file called /proc/sequence. The file, when +read, simply produces a set of increasing integer values, one per line. The +sequence will continue until the user loses patience and finds something +better to do. The file is seekable, in that one can do something like the +following: + + dd if=/proc/sequence of=out1 count=1 + dd if=/proc/sequence skip=1 out=out2 count=1 + +Then concatenate the output files out1 and out2 and get the right +result. Yes, it is a thoroughly useless module, but the point is to show +how the mechanism works without getting lost in other details. (Those +wanting to see the full source for this module can find it at +http://lwn.net/Articles/22359/). + + +The iterator interface + +Modules implementing a virtual file with seq_file must implement a simple +iterator object that allows stepping through the data of interest. +Iterators must be able to move to a specific position - like the file they +implement - but the interpretation of that position is up to the iterator +itself. A seq_file implementation that is formatting firewall rules, for +example, could interpret position N as the Nth rule in the chain. +Positioning can thus be done in whatever way makes the most sense for the +generator of the data, which need not be aware of how a position translates +to an offset in the virtual file. The one obvious exception is that a +position of zero should indicate the beginning of the file. + +The /proc/sequence iterator just uses the count of the next number it +will output as its position. + +Four functions must be implemented to make the iterator work. The first, +called start() takes a position as an argument and returns an iterator +which will start reading at that position. For our simple sequence example, +the start() function looks like: + + static void *ct_seq_start(struct seq_file *s, loff_t *pos) + { + loff_t *spos = kmalloc(sizeof(loff_t), GFP_KERNEL); + if (! spos) + return NULL; + *spos = *pos; + return spos; + } + +The entire data structure for this iterator is a single loff_t value +holding the current position. There is no upper bound for the sequence +iterator, but that will not be the case for most other seq_file +implementations; in most cases the start() function should check for a +"past end of file" condition and return NULL if need be. + +For more complicated applications, the private field of the seq_file +structure can be used. There is also a special value whch can be returned +by the start() function called SEQ_START_TOKEN; it can be used if you wish +to instruct your show() function (described below) to print a header at the +top of the output. SEQ_START_TOKEN should only be used if the offset is +zero, however. + +The next function to implement is called, amazingly, next(); its job is to +move the iterator forward to the next position in the sequence. The +example module can simply increment the position by one; more useful +modules will do what is needed to step through some data structure. The +next() function returns a new iterator, or NULL if the sequence is +complete. Here's the example version: + + static void *ct_seq_next(struct seq_file *s, void *v, loff_t *pos) + { + loff_t *spos = (loff_t *) v; + *pos = ++(*spos); + return spos; + } + +The stop() function is called when iteration is complete; its job, of +course, is to clean up. If dynamic memory is allocated for the iterator, +stop() is the place to free it. + + static void ct_seq_stop(struct seq_file *s, void *v) + { + kfree(v); + } + +Finally, the show() function should format the object currently pointed to +by the iterator for output. It should return zero, or an error code if +something goes wrong. The example module's show() function is: + + static int ct_seq_show(struct seq_file *s, void *v) + { + loff_t *spos = (loff_t *) v; + seq_printf(s, "%Ld\n", *spos); + return 0; + } + +We will look at seq_printf() in a moment. But first, the definition of the +seq_file iterator is finished by creating a seq_operations structure with +the four functions we have just defined: + + static struct seq_operations ct_seq_ops = { + .start = ct_seq_start, + .next = ct_seq_next, + .stop = ct_seq_stop, + .show = ct_seq_show + }; + +This structure will be needed to tie our iterator to the /proc file in +a little bit. + +It's worth noting that the interator value returned by start() and +manipulated by the other functions is considered to be completely opaque by +the seq_file code. It can thus be anything that is useful in stepping +through the data to be output. Counters can be useful, but it could also be +a direct pointer into an array or linked list. Anything goes, as long as +the programmer is aware that things can happen between calls to the +iterator function. However, the seq_file code (by design) will not sleep +between the calls to start() and stop(), so holding a lock during that time +is a reasonable thing to do. The seq_file code will also avoid taking any +other locks while the iterator is active. + + +Formatted output + +The seq_file code manages positioning within the output created by the +iterator and getting it into the user's buffer. But, for that to work, that +output must be passed to the seq_file code. Some utility functions have +been defined which make this task easy. + +Most code will simply use seq_printf(), which works pretty much like +printk(), but which requires the seq_file pointer as an argument. It is +common to ignore the return value from seq_printf(), but a function +producing complicated output may want to check that value and quit if +something non-zero is returned; an error return means that the seq_file +buffer has been filled and further output will be discarded. + +For straight character output, the following functions may be used: + + int seq_putc(struct seq_file *m, char c); + int seq_puts(struct seq_file *m, const char *s); + int seq_escape(struct seq_file *m, const char *s, const char *esc); + +The first two output a single character and a string, just like one would +expect. seq_escape() is like seq_puts(), except that any character in s +which is in the string esc will be represented in octal form in the output. + +There is also a function for printing filenames: + + int seq_path(struct seq_file *m, struct path *path, char *esc); + +Here, path indicates the file of interest, and esc is a set of characters +which should be escaped in the output. + + +Making it all work + +So far, we have a nice set of functions which can produce output within the +seq_file system, but we have not yet turned them into a file that a user +can see. Creating a file within the kernel requires, of course, the +creation of a set of file_operations which implement the operations on that +file. The seq_file interface provides a set of canned operations which do +most of the work. The virtual file author still must implement the open() +method, however, to hook everything up. The open function is often a single +line, as in the example module: + + static int ct_open(struct inode *inode, struct file *file) + { + return seq_open(file, &ct_seq_ops); + }; + +Here, the call to seq_open() takes the seq_operations structure we created +before, and gets set up to iterate through the virtual file. + +On a successful open, seq_open() stores the struct seq_file pointer in +file->private_data. If you have an application where the same iterator can +be used for more than one file, you can store an arbitrary pointer in the +private field of the seq_file structure; that value can then be retrieved +by the iterator functions. + +The other operations of interest - read(), llseek(), and release() - are +all implemented by the seq_file code itself. So a virtual file's +file_operations structure will look like: + + static struct file_operations ct_file_ops = { + .owner = THIS_MODULE, + .open = ct_open, + .read = seq_read, + .llseek = seq_lseek, + .release = seq_release + }; + +There is also a seq_release_private() which passes the contents of the +seq_file private field to kfree() before releasing the structure. + +The final step is the creation of the /proc file itself. In the example +code, that is done in the initialization code in the usual way: + + static int ct_init(void) + { + struct proc_dir_entry *entry; + + entry = create_proc_entry("sequence", 0, NULL); + if (entry) + entry->proc_fops = &ct_file_ops; + return 0; + } + + module_init(ct_init); + +And that is pretty much it. + + +seq_list + +If your file will be iterating through a linked list, you may find these +routines useful: + + struct list_head *seq_list_start(struct list_head *head, + loff_t pos); + struct list_head *seq_list_start_head(struct list_head *head, + loff_t pos); + struct list_head *seq_list_next(void *v, struct list_head *head, + loff_t *ppos); + +These helpers will interpret pos as a position within the list and iterate +accordingly. Your start() and next() functions need only invoke the +seq_list_* helpers with a pointer to the appropriate list_head structure. + + +The extra-simple version + +For extremely simple virtual files, there is an even easier interface. A +module can define only the show() function, which should create all the +output that the virtual file will contain. The file's open() method then +calls: + + int single_open(struct file *file, + int (*show)(struct seq_file *m, void *p), + void *data); + +When output time comes, the show() function will be called once. The data +value given to single_open() can be found in the private field of the +seq_file structure. When using single_open(), the programmer should use +single_release() instead of seq_release() in the file_operations structure +to avoid a memory leak. -- cgit v1.2.3 From ef40203a09823bc2c69168ffa626c46365e3ca2c Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Fri, 28 Mar 2008 11:22:38 -0600 Subject: Fill out information on patch tags in SubmittingPatches Add more information about the various patch tags in use, and try to establish a meaning for Reviewed-by: Signed-off-by: Jonathan Corbet --- Documentation/SubmittingPatches | 54 ++++++++++++++++++++++++++++++++++++++--- 1 file changed, 51 insertions(+), 3 deletions(-) diff --git a/Documentation/SubmittingPatches b/Documentation/SubmittingPatches index 08a1ed1cb5d8..cc00c8e8f040 100644 --- a/Documentation/SubmittingPatches +++ b/Documentation/SubmittingPatches @@ -328,7 +328,7 @@ now, but you can do this to mark internal company procedures or just point out some special detail about the sign-off. -13) When to use Acked-by: +13) When to use Acked-by: and Cc: The Signed-off-by: tag indicates that the signer was involved in the development of the patch, or that he/she was in the patch's delivery path. @@ -349,11 +349,59 @@ Acked-by: does not necessarily indicate acknowledgement of the entire patch.

These messages are a regression compared with 2.6.24, which did not flood the syslog with them. The actual underlying problem was introduced in 2.6.23, when somebody made the string parsing no longer accept nul-terminated strings as a valid input to store_uevent(). Eg. "add\0" was valid prior to 2.6.23, where the code regressed to require "add" without the '\0'. This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once again tolerate the trailing '\0', if present. According to GregKH, this mainly affects older Ubuntu systems, such as the one I have here that requires this fix.

In ip6_mc_input(), we need to check whether we have listener(s) for the packet. After commit ae7bf20a6316272acfcaef5d265b18aaa54b41e4, all packets for multicast destinations are delivered to upper layer if IFF_PROMISC or IFF_ALLMULTI is set. In fact, bug was rather ancient; the original (before the commit) intent of the dev->flags check was to skip the ipv6_chk_mcast_addr() call, assuming L2 filters packets appropriately, but it was even not true.

Build a new kernel when the configuration of the above options is - finished. -4. Install the new kernel. -5. Reboot your system. - -To use the driver as a module, proceed as follows: - -1. Enable 'loadable module support' in the kernel. -2. For automatic driver start, enable the 'Kernel module loader'. -3. Select the menu "Network device support" and then "Ethernet(1000Mbit)" -4. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support" - with (M) -5. Execute the command "make modules". -6. Execute the command "make modules_install". - The appropriate modules will be installed. -7. Reboot your system. - - -Load the module manually ------------------------- -To load the module manually, proceed as follows: - -1. Enter "modprobe sk98lin". -2. If a Marvell Yukon or SysKonnect SK-98xx adapter is installed in - your computer and you have a /proc file system, execute the command: - "ls /proc/net/sk98lin/" - This should produce an output containing a line with the following - format: - eth0 eth1 ... - which indicates that your adapter has been found and initialized. - - NOTE 1: If you have more than one Marvell Yukon or SysKonnect SK-98xx - adapter installed, the adapters will be listed as 'eth0', - 'eth1', 'eth2', etc. - For each adapter, repeat steps 3 and 4 below. - - NOTE 2: If you have other Ethernet adapters installed, your Marvell - Yukon or SysKonnect SK-98xx adapter will be mapped to the - next available number, e.g. 'eth1'. The mapping is executed - automatically. - The module installation message (displayed either in a system - log file or on the console) prints a line for each adapter - found containing the corresponding 'ethX'. - -3. Select an IP address and assign it to the respective adapter by - entering: - ifconfig eth0 - With this command, the adapter is connected to the Ethernet. - - SK-98xx Gigabit Ethernet Server Adapters: The yellow LED on the adapter - is now active, the link status LED of the primary port is active and - the link status LED of the secondary port (on dual port adapters) is - blinking (if the ports are connected to a switch or hub). - SK-98xx V2.0 Gigabit Ethernet Adapters: The link status LED is active. - In addition, you will receive a status message on the console stating - "ethX: network connection up using port Y" and showing the selected - connection parameters (x stands for the ethernet device number - (0,1,2, etc), y stands for the port name (A or B)). - - NOTE: If you are in doubt about IP addresses, ask your network - administrator for assistance. - -4. Your adapter should now be fully operational. - Use 'ping ' to verify the connection to other computers - on your network. -5. To check the adapter configuration view /proc/net/sk98lin/[devicename]. - For example by executing: - "cat /proc/net/sk98lin/eth0" - -Unload the module ------------------ -To stop and unload the driver modules, proceed as follows: - -1. Execute the command "ifconfig eth0 down". -2. Execute the command "rmmod sk98lin". - -3.2 Inclusion of adapter at system start ------------------------------------------ - -Since a large number of different Linux distributions are -available, we are unable to describe a general installation procedure -for the driver module. -Because the driver is now integrated in the kernel, installation should -be easy, using the standard mechanism of your distribution. -Refer to the distribution's manual for installation of ethernet adapters. - -*** - -4 Driver Parameters -==================== - -Parameters can be set at the command line after the module has been -loaded with the command 'modprobe'. -In some distributions, the configuration tools are able to pass parameters -to the driver module. - -If you use the kernel module loader, you can set driver parameters -in the file /etc/modprobe.conf (or /etc/modules.conf in 2.4 or earlier). -To set the driver parameters in this file, proceed as follows: - -1. Insert a line of the form : - options sk98lin ... - For "...", the same syntax is required as described for the command - line parameters of modprobe below. -2. To activate the new parameters, either reboot your computer - or - unload and reload the driver. - The syntax of the driver parameters is: - - modprobe sk98lin parameter=value1[,value2[,value3...]] - - where value1 refers to the first adapter, value2 to the second etc. - -NOTE: All parameters are case sensitive. Write them exactly as shown - below. - -Example: -Suppose you have two adapters. You want to set auto-negotiation -on the first adapter to ON and on the second adapter to OFF. -You also want to set DuplexCapabilities on the first adapter -to FULL, and on the second adapter to HALF. -Then, you must enter: - - modprobe sk98lin AutoNeg_A=On,Off DupCap_A=Full,Half - -NOTE: The number of adapters that can be configured this way is - limited in the driver (file skge.c, constant SK_MAX_CARD_PARAM). - The current limit is 16. If you happen to install - more adapters, adjust this and recompile. - - -4.1 Per-Port Parameters ------------------------- - -These settings are available for each port on the adapter. -In the following description, '?' stands for the port for -which you set the parameter (A or B). - -Speed ------ -Parameter: Speed_? -Values: 10, 100, 1000, Auto -Default: Auto - -This parameter is used to set the speed capabilities. It is only valid -for the SK-98xx V2.0 copper adapters. -Usually, the speed is negotiated between the two ports during link -establishment. If this fails, a port can be forced to a specific setting -with this parameter. - -Auto-Negotiation ----------------- -Parameter: AutoNeg_? -Values: On, Off, Sense -Default: On - -The "Sense"-mode automatically detects whether the link partner supports -auto-negotiation or not. - -Duplex Capabilities -------------------- -Parameter: DupCap_? -Values: Half, Full, Both -Default: Both - -This parameters is only relevant if auto-negotiation for this port is -not set to "Sense". If auto-negotiation is set to "On", all three values -are possible. If it is set to "Off", only "Full" and "Half" are allowed. -This parameter is useful if your link partner does not support all -possible combinations. - -Flow Control ------------- -Parameter: FlowCtrl_? -Values: Sym, SymOrRem, LocSend, None -Default: SymOrRem - -This parameter can be used to set the flow control capabilities the -port reports during auto-negotiation. It can be set for each port -individually. -Possible modes: - -- Sym = Symmetric: both link partners are allowed to send - PAUSE frames - -- SymOrRem = SymmetricOrRemote: both or only remote partner - are allowed to send PAUSE frames - -- LocSend = LocalSend: only local link partner is allowed - to send PAUSE frames - -- None = no link partner is allowed to send PAUSE frames - -NOTE: This parameter is ignored if auto-negotiation is set to "Off". - -Role in Master-Slave-Negotiation (1000Base-T only) --------------------------------------------------- -Parameter: Role_? -Values: Auto, Master, Slave -Default: Auto - -This parameter is only valid for the SK-9821 and SK-9822 adapters. -For two 1000Base-T ports to communicate, one must take the role of the -master (providing timing information), while the other must be the -slave. Usually, this is negotiated between the two ports during link -establishment. If this fails, a port can be forced to a specific setting -with this parameter. - - -4.2 Adapter Parameters ------------------------ - -Connection Type (SK-98xx V2.0 copper adapters only) ---------------- -Parameter: ConType -Values: Auto, 100FD, 100HD, 10FD, 10HD -Default: Auto - -The parameter 'ConType' is a combination of all five per-port parameters -within one single parameter. This simplifies the configuration of both ports -of an adapter card! The different values of this variable reflect the most -meaningful combinations of port parameters. - -The following table shows the values of 'ConType' and the corresponding -combinations of the per-port parameters: - - ConType | DupCap AutoNeg FlowCtrl Role Speed - ----------+------------------------------------------------------ - Auto | Both On SymOrRem Auto Auto - 100FD | Full Off None Auto (ignored) 100 - 100HD | Half Off None Auto (ignored) 100 - 10FD | Full Off None Auto (ignored) 10 - 10HD | Half Off None Auto (ignored) 10 - -Stating any other port parameter together with this 'ConType' variable -will result in a merged configuration of those settings. This due to -the fact, that the per-port parameters (e.g. Speed_? ) have a higher -priority than the combined variable 'ConType'. - -NOTE: This parameter is always used on both ports of the adapter card. - -Interrupt Moderation --------------------- -Parameter: Moderation -Values: None, Static, Dynamic -Default: None - -Interrupt moderation is employed to limit the maximum number of interrupts -the driver has to serve. That is, one or more interrupts (which indicate any -transmit or receive packet to be processed) are queued until the driver -processes them. When queued interrupts are to be served, is determined by the -'IntsPerSec' parameter, which is explained later below. - -Possible modes: - - -- None - No interrupt moderation is applied on the adapter card. - Therefore, each transmit or receive interrupt is served immediately - as soon as it appears on the interrupt line of the adapter card. - - -- Static - Interrupt moderation is applied on the adapter card. - All transmit and receive interrupts are queued until a complete - moderation interval ends. If such a moderation interval ends, all - queued interrupts are processed in one big bunch without any delay. - The term 'static' reflects the fact, that interrupt moderation is - always enabled, regardless how much network load is currently - passing via a particular interface. In addition, the duration of - the moderation interval has a fixed length that never changes while - the driver is operational. - - -- Dynamic - Interrupt moderation might be applied on the adapter card, - depending on the load of the system. If the driver detects that the - system load is too high, the driver tries to shield the system against - too much network load by enabling interrupt moderation. If - at a later - time - the CPU utilization decreases again (or if the network load is - negligible) the interrupt moderation will automatically be disabled. - -Interrupt moderation should be used when the driver has to handle one or more -interfaces with a high network load, which - as a consequence - leads also to a -high CPU utilization. When moderation is applied in such high network load -situations, CPU load might be reduced by 20-30%. - -NOTE: The drawback of using interrupt moderation is an increase of the round- -trip-time (RTT), due to the queueing and serving of interrupts at dedicated -moderation times. - -Interrupts per second ---------------------- -Parameter: IntsPerSec -Values: 30...40000 (interrupts per second) -Default: 2000 - -This parameter is only used if either static or dynamic interrupt moderation -is used on a network adapter card. Using this parameter if no moderation is -applied will lead to no action performed. - -This parameter determines the length of any interrupt moderation interval. -Assuming that static interrupt moderation is to be used, an 'IntsPerSec' -parameter value of 2000 will lead to an interrupt moderation interval of -500 microseconds. - -NOTE: The duration of the moderation interval is to be chosen with care. -At first glance, selecting a very long duration (e.g. only 100 interrupts per -second) seems to be meaningful, but the increase of packet-processing delay -is tremendous. On the other hand, selecting a very short moderation time might -compensate the use of any moderation being applied. - - -Preferred Port --------------- -Parameter: PrefPort -Values: A, B -Default: A - -This is used to force the preferred port to A or B (on dual-port network -adapters). The preferred port is the one that is used if both are detected -as fully functional. - -RLMT Mode (Redundant Link Management Technology) ------------------------------------------------- -Parameter: RlmtMode -Values: CheckLinkState,CheckLocalPort, CheckSeg, DualNet -Default: CheckLinkState - -RLMT monitors the status of the port. If the link of the active port -fails, RLMT switches immediately to the standby link. The virtual link is -maintained as long as at least one 'physical' link is up. - -Possible modes: - - -- CheckLinkState - Check link state only: RLMT uses the link state - reported by the adapter hardware for each individual port to - determine whether a port can be used for all network traffic or - not. - - -- CheckLocalPort - In this mode, RLMT monitors the network path - between the two ports of an adapter by regularly exchanging packets - between them. This mode requires a network configuration in which - the two ports are able to "see" each other (i.e. there must not be - any router between the ports). - - -- CheckSeg - Check local port and segmentation: This mode supports the - same functions as the CheckLocalPort mode and additionally checks - network segmentation between the ports. Therefore, this mode is only - to be used if Gigabit Ethernet switches are installed on the network - that have been configured to use the Spanning Tree protocol. - - -- DualNet - In this mode, ports A and B are used as separate devices. - If you have a dual port adapter, port A will be configured as eth0 - and port B as eth1. Both ports can be used independently with - distinct IP addresses. The preferred port setting is not used. - RLMT is turned off. - -NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations - where a network path between the ports on one adapter exists. - Moreover, they are not designed to work where adapters are connected - back-to-back. -*** - - -5 Large Frame Support -====================== - -The driver supports large frames (also called jumbo frames). Using large -frames can result in an improved throughput if transferring large amounts -of data. -To enable large frames, set the MTU (maximum transfer unit) of the -interface to the desired value (up to 9000), execute the following -command: - ifconfig eth0 mtu 9000 -This will only work if you have two adapters connected back-to-back -or if you use a switch that supports large frames. When using a switch, -it should be configured to allow large frames and auto-negotiation should -be set to OFF. The setting must be configured on all adapters that can be -reached by the large frames. If one adapter is not set to receive large -frames, it will simply drop them. - -You can switch back to the standard ethernet frame size by executing the -following command: - ifconfig eth0 mtu 1500 - -To permanently configure this setting, add a script with the 'ifconfig' -line to the system startup sequence (named something like "S99sk98lin" -in /etc/rc.d/rc2.d). -*** - - -6 VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad) -================================================================== - -The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and -Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad. -These features are only available after installation of open source -modules available on the Internet: -For VLAN go to: http://www.candelatech.com/~greear/vlan.html -For Link Aggregation go to: http://www.st.rim.or.jp/~yumo - -NOTE: SysKonnect GmbH does not offer any support for these open source - modules and does not take the responsibility for any kind of - failures or problems arising in connection with these modules. - -NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may - cause problems when unloading the driver. - - -7 Troubleshooting -================== - -If any problems occur during the installation process, check the -following list: - - -Problem: The SK-98xx adapter cannot be found by the driver. -Solution: In /proc/pci search for the following entry: - 'Ethernet controller: SysKonnect SK-98xx ...' - If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has - been found by the system and should be operational. - If this entry does not exist or if the file '/proc/pci' is not - found, there may be a hardware problem or the PCI support may - not be enabled in your kernel. - The adapter can be checked using the diagnostics program which - is available on the SysKonnect web site: - www.syskonnect.com - - Some COMPAQ machines have problems dealing with PCI under Linux. - This problem is described in the 'PCI howto' document - (included in some distributions or available from the - web, e.g. at 'www.linux.org'). - - -Problem: Programs such as 'ifconfig' or 'route' cannot be found or the - error message 'Operation not permitted' is displayed. -Reason: You are not logged in as user 'root'. -Solution: Logout and login as 'root' or change to 'root' via 'su'. - - -Problem: Upon use of the command 'ping

Wysocki" Date: Sun, 30 Mar 2008 02:19:07 +0100 Subject: ACPI PM: Restore the 2.6.24 suspend ordering MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some time ago it turned out that our suspend code ordering broke some NVidia-based systems that hung if _PTS was executed with one of the PCI devices, specifically a USB controller, in a low power state. Then, it was noticed that the suspend code ordering was not compliant with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and it was argued that the code had to be changed for that reason (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). So we did, but evidently we did wrong, because it's now turning out that some systems have been broken by this change. Refs: http://bugzilla.kernel.org/show_bug.cgi?id=10340 https://bugzilla.novell.com/show_bug.cgi?id=374217#c16 [ I said at that time that something like this might happend, but the majority of people involved thought that it was improbable due to the necessity to preserve the compliance of hardware with ACPI 1.0. ] This actually is a quite serious regression from 2.6.24. Moreover, the ACPI 1.0 ordering of suspend code introduced another issue that I have only noticed recently. Namely, if the suspend of one of devices fails, the already suspended devices will be resumed without executing _WAK before, which leads to problems on some systems (for example, in such situations thermal management is broken on my HP nx6325). Consequently, it also breaks suspend debugging on the affected systems. Note also, that the requirement to execute _PTS before suspending devices does not really make sense, because the device in question may be put into a low power state at run time for a reason unrelated to a system-wide suspend. For the reasons outlined above, the change of the suspend ordering should be reverted, which is done by the patch below. [ Felix Möller: "I am the reporter from the original Novell Bug: https://bugzilla.novell.com/show_bug.cgi?id=374217 I just tried current git head (two hours ago) with the patch (the one from the beginning of this thread) from Rafael and without it. With the patch my MacBook does suspend without it does not." ] Signed-off-by: Rafael J.

It seems the first xxxx bytes of the data are in first sg entry, and remaining xx bytes are in next sg entry. But we don't check next sg entry to see if we need to go look the page up. I noticed in hmac.c, we do a scatterwalk_sg_next(), to do this check and possible lookup, thus xcbc.c needs to use this routine too. A 15-hour run of an ipsec stress test sending streams of tcp and udp packets of various sizes, using this patch and aes-xcbc-mac completed successfully, so hopefully this fixes the problem.

So if you do: if (b_pfn <= (min_t(u64, 0xffffffff, BLK_BOUNCE_HIGH) >> PAGE_SHIFT)) dma = 1 that will translate to: if (BLK_BOUNCE_HIGH <= BLK_BOUNCE_HIGH) dma = 1 So for 99% of hardware this will trigger unnecessary GFP_DMA allocations and isa pooling operations. Also note how the 32bit code still does b_pfn < blk_max_low_pfn. I guess this is what you were looking after. I didn't verify but as far as I can tell, this will stop the regression with isa dma operations at boot for 99% of blkdev/memory combinations out there and I guess this fixes the setups with >4G of ram and 32bit pci cards as well (this also retains symmetry with the 32bit code).

The changes introduced in commit 063a2da8f01806906f7d7b1a1424b9afddebc443 changed the semantics of the num_interrupt_in, num_interrupt_out, num_bulk_in and num_bulk_out entries of the usb_serial_driver struct to be the number of endpoints the device has when probed. This patch changes the ti_1port_device usb_serial_driver struct to reflect this change. The single port devices only have 1 bulk_out endpoint in their initial configuration, and so this patch changes the number of other types to NUM_DONT_CARE. The same change probably needs doing to the ti_2port_device struct, but I don't have a two port device at hand.

Fixes the keyspan driver after the addition of additional checking of driver requirements introduced in usb-serial.c commit 063a2da8f01806906f7d7b1a1424b9afddebc443. The initialization of the keyspan usb_serial_driver structs were not initializing the num_interrupt_out field and the additional checking was rejecting the end point so the driver wouldn't finish initializing. This commit initializes the fields to NUM_DONT_CARE. It works for the keyspan USA-49WG and doesn't break the USA-19HS which are the two keyspan devices I have to test with.

One way of solving the issue is to enhance Kbuild, but Avi and David conviced me, that changing headers_install is not the way to go. This patch changes the definition for linux/kvm.h to unifdef-y. If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all architectures without asm/kvm.h. Therefore, this patch also provides asm/kvm.h on all architectures.

This patch adds the symbol "phys_base" to a vmcoreinfo data. The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile (dump filtering command) gets it to distinguish unnecessary pages, and makedumpfile creates a small dumpfile. On x86_64 kernel which compiled with CONFIG_PHYSICAL_START=0x0 and CONFIG_RELOCATABLE=y, makedumpfile fails like the following: # makedumpfile -d31 /proc/vmcore dumpfile The kernel version is not supported. The created dumpfile may be incomplete. _exclude_free_page: Can't get next online node. makedumpfile Failed. # The cause is the lack of the symbol "phys_base" in a vmcoreinfo data. If the symbol "phys_base" does not exist, makedumpfile considers an x86_64 kernel as non relocatable. As the result, makedumpfile misunderstands the physical address where the kernel is loaded, and it cannot translate a kernel virtual address to physical address correctly. To fix this problem, this patch adds the symbol "phys_base" to a vmcoreinfo data. Signed-off-by: Ken'ichi Ohmichi Cc: "Eric W.

The quiescent state is reached once all the currently running preempt_disable regions are done running. We use the call_rcu mechanism to execute kfree() after such quiescent state has been reached. However, the new CONFIG_PREEMPT_RCU version of call_rcu and rcu_barrier does not guarantee that all preempt_disable code regions have finished, hence the race. The "proper" way to do this is to use rcu_read_lock/unlock, but we don't want to use it to minimize intrusiveness on the traced system. (we do not want the marker code to call into much of the OS code, because it would quickly restrict what can and cannot be instrumented, such as the scheduler). The temporary fix, until we get call_rcu_sched and rcu_barrier_sched in mainline, is to use synchronize_sched before each call_rcu calls, so we wait for the quiescent state in the system call code path. It will slow down batch marker enable/disable, but will make sure the race is gone. Signed-off-by: Mathieu Desnoyers Acked-by: Paul E.

On this platform, we must not normally clear MSR:EE (the hardware external interrupt enable) except for short periods of time. Taking an interrupt while soft-disabled doesn't cause us to clear it for example. The iSeries kernel expects to mostly run with MSR:EE enabled at all times except in a few exception entry/exit code paths. Thus local_irq_enable() doesn't check if it needs to hard-enable as it expects this to be unnecessary on iSeries. However, hard_irq_disable() _does_ cause MSR:EE to be cleared, including on iSeries. A call to it was recently added to the context switch code, thus causing interrupts to become disabled for a long periods of time, causing the iSeries watchdog to kick in under some circumstances and other nasty things. This patch fixes it by making local_irq_enable() properly re-enable MSR:EE on iSeries. It basically removes a return statement here to make iSeries use the same code path as everybody else. That does mean that we might occasionally get spurious decrementer interrupts but I don't think that matters. Another option would have been to make hard_irq_disable() a nop on iSeries but I didn't like it much, in case we have good reasons to hard-disable. Part of the patch is fixes to make sure the hard_enabled PACA field is properly set on iSeries as it used not to be before, since it was mostly unused.

Furthermore this adds the settings for the PHY in the dts file for the Lite5200. Note, that this is not exactly the same as in the Lite5200B, because the PHY is located at f0003000:01 for the 5200, and at :00 for the 5200B.

That is, if the initial xfrm_lookup let the packet pass, we will stand by that decision should the relookup fail due to an error. This should be safe from a security point-of-view because compliant systems must install a default deny policy so the packet would'nt have passed in that case.

A PV OS has two grant table data structures: the grant table itself and a free list. The free list is composed of an array of pages, which grow dynamically as the guest OS requires more grants. While the grant table contains 8-byte entries, the free list contains 4-byte entries. So we have half as many pages in the free list than in the grant table. There was a bug in the free list allocation code. The free list was indexed as if it was the same size as the grant table. But it's only half as large. So memory got corrupted, and I was seeing crashes in the slab allocator later on.

This can cause time jumps in the range of hours. This was reported in: http://lkml.org/lkml/2007/8/23/96 and http://lkml.org/lkml/2008/3/31/23 I was able to reproduce the problem with a gettimeofday loop test on a dual core and a quad core machine which both have sychronized TSCs. The TSCs seems not to be perfectly in sync though, but the kernel is not able to detect the slight delta in the sync check. Still there exists an extremly small window where this delta can be observed with a real big time jump. So far I was only able to reproduce this with the vsyscall gettimeofday implementation, but in theory this might be observable with the syscall based version as well. CPU 0 updates the clock source variables under xtime/vyscall lock and CPU1, where the TSC is slighty behind CPU0, is reading the time right after the seqlock was unlocked. The clocksource reference data was updated with the TSC from CPU0 and the value which is read from TSC on CPU1 is less than the reference data. This results in a huge delta value due to the unsigned subtraction of the TSC value and the reference value. This algorithm can not be changed due to the support of wrapping clock sources like pm timer. The huge delta is converted to nanoseconds and added to xtime, which is then observable by the caller. The next gettimeofday call on CPU1 will show the correct time again as now the TSC has advanced above the reference value. To prevent this TSC specific wreckage we need to compare the TSC value against the reference value and return the latter when it is larger than the actual TSC value. I pondered to mark the TSC unstable when the readout is smaller than the reference value, but this would render an otherwise good and fast clocksource unusable without a real good reason.

Since the read of the old status was not synchronized with anything, an aggressive CPU re-ordering of memory accesses might have moved that read up to before the data was even written to the buffer, and another CPU that cleaned it again, causing the newly dirty state to never actually hit the disk. Admittedly this would probably never trigger in practice, but it's still wrong. Mikulas sent a patch that fixed the problem, but I dislike the subtlety of the whole optimization, so this is an alternate fix that is more explicit about the particular SMP ordering for the optimization, and separates out the speculative reads of the buffer state into its own conditional (and makes the memory barrier only happen if we are likely to actually hit the optimized case in the first place). I considered removing the optimization entirely, but Andrew argued for it's continued existence. I'm a push-over.

Any additional effects (e.g. not allocating metadata) are up to the foo subsystem. This doesn't handle early_init subsystems (their "disabled" bit isn't set be, but it could easily be extended to do so if any of the early_init systems wanted it - I think it would just involve some nastier parameter processing since it would occur before the command-line argument parser had been run.

I'm no expert on distros, they may have no interest whatever in CONFIG_CGROUP_MEM_RES_CTLR=y; and the rest of us can easily build with or without it, or apply the cgroup_disable=memory patches.

It is a good idea to add it, since it saves memory for people who want to turn off the memory controller. By default the option is on for the following two reasons: 1. It provides compatibility with the current scheme where the memory controller turns on if the config option is enabled 2. It allows for wider testing of the memory controller, once the config option is enabled We still allow the create, destroy callbacks to succeed, since they are not aware of boot options. We do not populate the directory will memory resource controller specific files.

Not so intensive read/write operations cause incomplete writes which lead to kernel panics in JFFS2. We investigated the issue - it is caused by bug in FL_SHUTDOWN parsing code. Sometimes chip returns -EIO as if it is in FL_SHUTDOWN state when it should wait in FL_PONT (error in order of conditions). The following patch fixes the bug in state parsing code of CFI.

So on systems with multiple BMC interfaces, the ipmi device names are being created in reverse order relative to how they are discovered on the system (e.g. on an IBM x3950 multinode server with N nodes, the device name for the BMC in the first node is /dev/ipmiN-1 and the device name for the BMC in the last node is /dev/ipmi0, etc.). The problem is caused by the list handling routines chosen in dmi_scan.c. Using list_add() causes the multiple ipmi devices to be added to the device list using a stack-paradigm and so the ipmi driver subsequently pulls them off during initialization in LIFO order. This patch changes the dmi_save_ipmi_device() list handling paradigm to a queue, thereby allowing the ipmi driver to build the ipmi device names in the order in which they are found on the system.

Signature: 6000 pages under writeback but never getting written; most tasks of interest trying to reclaim, but each get_swap_bio waiting for a bio in mempool_alloc's io_schedule_timeout(5*HZ); every five seconds an atomic page allocation failure report from kblockd failing to allocate a sense_buffer in __scsi_get_command. __scsi_get_command has a (one item) free_list to protect against this, but rc1's [SCSI] use dynamically allocated sense buffer de25deb18016f66dcdede165d07654559bb332bc upset that slightly. When it fails to allocate from the separate sense_slab, instead of giving up, it must fall back to the command free_list, which is sure to have a sense_buffer attached. Either my earlier -rc testing missed this, or there's some recent contributory factor. One very significant factor is SLUB, which merges slab caches when it can, and on 64-bit happens to merge both bio cache and sense_slab cache into kmalloc's 128-byte cache: so that under this swapping load, bios above are liable to gobble up all the slots needed for scsi_cmnd sense_buffers below. That's disturbing behaviour, and I tried a few things to fix it. Adding a no-op constructor to the sense_slab inhibits SLUB from merging it, and stops all the allocation failures I was seeing; but it's rather a hack, and perhaps in different configurations we have other caches on the swapout path which are ill-merged. Another alternative is to revert the separate sense_slab, using cache-line-aligned sense_buffer allocated beyond scsi_cmnd from the one kmem_cache; but that might waste more memory, and is only a way of diverting around the known problem. While I don't like seeing the allocation failures, and hate the idea of all those bios piled up above a scsi host working one by one, it does seem to emerge fairly soon with the livelock fix. So lacking better ideas, stick with that one clear fix for now.

The 'disable_cb' callback is designed as an optimization to tell the host we don't need callbacks now. As it is not reliable, the debug check is overzealous: it can happen on two CPUs at the same time. Document this. Even if it were reliable, the virtio_net driver doesn't disable callbacks on transmit so the START_USE/END_USE debugging reentrance protection can be easily tripped even on UP. Thanks to Balaji Rao for the bug report and testing.

With GSO the whole head skb was marked as LOST which is in violation of NewReno procedure that only wants to mark one packet and ended up breaking our TCP code by causing counter overflow because our code was built on top of assumption about valid NewReno procedure. This manifested as triggering a WARN_ON for the overflow in a number of places. It seems relatively safe alternative to just do nothing if tcp_fragment fails due to oom because another duplicate ACK is likely to be received soon and the fragmentation will be retried. Special thanks goes to Soeren Sonnenburg who was lucky enough to be able to reproduce this so that the warning for the overflow was hit. It's not as easy task as it seems even if this bug happens quite often because the amount of outstanding data is pretty significant for the mismarkings to lead to an overflow. Because it's very late in 2.6.25-rc cycle (if this even makes in time), I didn't want to touch anything with SACK enabled here. Fragmenting might be useful for it as well but it's more or less a policy decision rather than mandatory fix. Thus there's no need to rush and we can postpone considering tcp_fragment with SACK for 2.6.26. In 2.6.24 and earlier, this very same bug existed but the effect is slightly different because of a small changes in the if conditions that fit to the patch's context. With them nothing got lost marker and thus no retransmissions happened. Signed-off-by: Ilpo Järvinen Signed-off-by: David S.

The simplest scenario I can currently think of is rather complex in practice (there might be some more straightforward cases though). Ie., if mss is reduced during mtu probing, it may end up marking everything lost and if some duplicate ACKs arrived prior to that sacked_out will be non-zero as well, leading to S+L > packets_out, tcp_clean_rtx_queue on the next cumulative ACK or tcp_fastretrans_alert on the next duplicate ACK will fix the S counter. More straightforward (but questionable) solution would be to just call tcp_reset_reno_sack() in tcp_simple_retransmit but it would negatively impact the probe's retransmission, ie., the retransmissions would not occur if some duplicate ACKs had arrived. So I had to add reno sacked_out reseting to CA_Loss state when the first cumulative ACK arrives (this stale sacked_out might actually be the explanation for the reports of left_out overflows in kernel prior to 2.6.23 and S+L overflow reports of 2.6.24). However, this alone won't be enough to fix kernel before 2.6.24 because it is building on top of the commit 1b6d427bb7e ([TCP]: Reduce sacked_out with reno when purging write_queue) to keep the sacked_out from overflowing.

Miller" Date: Tue, 8 Apr 2008 16:50:44 -0700 Subject: [NET]: Undo code bloat in hot paths due to print_mac(). If print_mac() is used inside of a pr_debug() the compiler can't see that the call is redundant so still performs it even of pr_debug() ends up being a nop. So don't use print_mac() in such cases in hot code paths, use MAC_FMT et al. instead. As noted by Joe Perches, pr_debug() could be modified to handle this better, but that is a change to an interface used by the entire kernel and thus needs to be validated carefully. This here is thus the less risky fix for 2.6.25 Signed-off-by: David S.

Since we have dequeued it by that time, it means leaking requests and hanging processes, which is why BUG() was in there. In ub this happens if a packet request ends normally, but with residue (e.g. when scsi_id issues INQUIRY). The fix is to make sure that arguments passed to __blk_end_request are correct: the full request length and not just transferred length. The transferred length is indicated to applications by adjusting rq->data_len with old, unchanged code outside of this patch.

(If CONFIG_HIGHMEM=n, always "true") This check is used for testing whether we can use kmalloc_node() on a node. Then, if there is a node which only contains HIGHMEM, the system will call kmalloc_node() which doesn't contain memory for the kernel. If it happens under SLUB, the kernel will panic.

This patch adds a version of the wait function that just pure polls. While this is not very elegant in principle, it's very likely the easiest thing to do here, we already checked if the chip was ready (while yielding) just before, so it is very unlikely to take a long time here.

Get rid of the loop and pass back -EAGAIN correctly from __generic_file_splice_read(), so we handle that condition properly as well.

The pattern that can trigger that is the following: - elevator switch from cfq to something else; - module unloading, with elv_unregister() that calls cfq_free_io_context() on ioc freeing the cic (via the .trim op); - module gets reloaded and the elevator switches back to cfq; - reallocation of a cic at the same address as before (with a valid key). To fix it just assign NULL to ioc_data in __cfq_exit_single_io_context(), that is called from the regular exit path and from the elevator switching code. The only path that frees a cic and is not covered is the error handling one, but cic's freed in this way are never cached in ioc_data.

It's because of this test in do_ip_getsockopt(): if (len < sizeof(int) && len > 0 && val>=0 && val<255) { It should allow a 'val' of 255 to pass here, but it doesn't so it copies a full 'int' back to userspace.

Earlier commit 40d6a146629b98d8e322b6f9332b182c7cbff3df added smp_call_function in cpu_idle_wait() to kick cpus that are in tickless idle. Looking at cpu_idle_wait code at that time, code seemed to be over-engineered for a case which is rarely used (while changing idle handler). Below is a simplified version of cpu_idle_wait, which just makes a dummy smp_call_function to all cpus, to make them come out of old idle handler and start using the new idle handler. It eliminates code in the idle loop to handle cpu_idle_wait.

The tail/sibling-call optimization is not the only way that the compiler can decide to use stack argument words as scratch space, which we have to prevent. Other optimizations can do it too. Until we have new compiler support to make "asmlinkage" binding on the compiler's own use of the stack argument frame, we have work around all the manifestations of this issue that crop up. More cases seem to be prevented by also keeping the incoming argument variables live at the end of the function. This makes their original stack slots attractive places to leave those variables, so the compiler tends not clobber them for something else. It's still no guarantee, but it handles some observed cases that prevent_tail_call() did not.

We currently use an unsigned char, which limits us to 256 devices per protocol. This patch changes that to an unsigned int. Not all backends can take advantage of this: we limit ISAPNP to 10 devices in isapnp_cfg_begin(), and PNPBIOS is limited to 256 devices because the BIOS interfaces use a one-byte device node number. But there is no limit on the number of PNPACPI devices we may have. Large HP Integrity machines have more than 256, which causes the current "unsigned char number" to wrap around. This causes errors like this: pnp: PnP ACPI init kobject_add failed for 00:00 with -EEXIST, don't try to register things with the same name in the same directory.

It should not have any adverse effect on ISAPNP or PNPBIOS because their limits are still enforced in the backends.

If no +entry is found, a new entry will be create, added to the cache, and +marked as not containing valid data. + +The item returned is typically passed to cache_check which will check +if the data is valid, and may initiate an up-call to get fresh data. +cache_check will return -ENOENT in the entry is negative or if an up +call is needed but not possible, -EAGAIN if an upcall is pending, +or 0 if the data is valid; + +cache_check can be passed a "struct cache_req *". This structure is +typically embedded in the actual request and can be used to create a +deferred copy of the request (struct cache_deferred_req). This is +done when the found cache item is not uptodate, but the is reason to +believe that userspace might provide information soon. When the cache +item does become valid, the deferred copy of the request will be +revisited (->revisit). It is expected that this method will +reschedule the request for processing. + +The value returned by sunrpc_cache_lookup can also be passed to +sunrpc_cache_update to set the content for the item. A second item is +passed which should hold the content. If the item found by _lookup +has valid data, then it is discarded and a new item is created. This +saves any user of an item from worrying about content changing while +it is being inspected. If the item found by _lookup does not contain +valid data, then the content is copied across and CACHE_VALID is set. + +Populating a cache +------------------ + +Each cache has a name, and when the cache is registered, a directory +with that name is created in /proc/net/rpc + +This directory contains a file called 'channel' which is a channel +for communicating between kernel and user for populating the cache. +This directory may later contain other files of interacting +with the cache. + +The 'channel' works a bit like a datagram socket. Each 'write' is +passed as a whole to the cache for parsing and interpretation. +Each cache can treat the write requests differently, but it is +expected that a message written will contain: + - a key + - an expiry time + - a content. +with the intention that an item in the cache with the give key +should be create or updated to have the given content, and the +expiry time should be set on that item. + +Reading from a channel is a bit more interesting. When a cache +lookup fails, or when it succeeds but finds an entry that may soon +expire, a request is lodged for that cache item to be updated by +user-space. These requests appear in the channel file. + +Successive reads will return successive requests. +If there are no more requests to return, read will return EOF, but a +select or poll for read will block waiting for another request to be +added. + +Thus a user-space helper is likely to: + open the channel. + select for readable + read a request + write a response + loop. + +If it dies and needs to be restarted, any requests that have not been +answered will still appear in the file and will be read by the new +instance of the helper. + +Each cache should define a "cache_parse" method which takes a message +written from user-space and processes it. It should return an error +(which propagates back to the write syscall) or 0. + +Each cache should also define a "cache_request" method which +takes a cache item and encodes a request into the buffer +provided. + +Note: If a cache has no active readers on the channel, and has had not +active readers for more than 60 seconds, further requests will not be +added to the channel but instead all lookups that do not find a valid +entry will fail. This is partly for backward compatibility: The +previous nfs exports table was deemed to be authoritative and a +failed lookup meant a definite 'no'. + +request/response format +----------------------- + +While each cache is free to use it's own format for requests +and responses over channel, the following is recommended as +appropriate and support routines are available to help: +Each request or response record should be printable ASCII +with precisely one newline character which should be at the end. +Fields within the record should be separated by spaces, normally one. +If spaces, newlines, or nul characters are needed in a field they +much be quoted. two mechanisms are available: +1/ If a field begins '\x' then it must contain an even number of + hex digits, and pairs of these digits provide the bytes in the + field. +2/ otherwise a \ in the field must be followed by 3 octal digits + which give the code for a byte.

If no -entry is found, a new entry will be create, added to the cache, and -marked as not containing valid data. - -The item returned is typically passed to cache_check which will check -if the data is valid, and may initiate an up-call to get fresh data. -cache_check will return -ENOENT in the entry is negative or if an up -call is needed but not possible, -EAGAIN if an upcall is pending, -or 0 if the data is valid; - -cache_check can be passed a "struct cache_req *". This structure is -typically embedded in the actual request and can be used to create a -deferred copy of the request (struct cache_deferred_req). This is -done when the found cache item is not uptodate, but the is reason to -believe that userspace might provide information soon. When the cache -item does become valid, the deferred copy of the request will be -revisited (->revisit). It is expected that this method will -reschedule the request for processing. - -The value returned by sunrpc_cache_lookup can also be passed to -sunrpc_cache_update to set the content for the item. A second item is -passed which should hold the content. If the item found by _lookup -has valid data, then it is discarded and a new item is created. This -saves any user of an item from worrying about content changing while -it is being inspected. If the item found by _lookup does not contain -valid data, then the content is copied across and CACHE_VALID is set. - -Populating a cache ------------------- - -Each cache has a name, and when the cache is registered, a directory -with that name is created in /proc/net/rpc - -This directory contains a file called 'channel' which is a channel -for communicating between kernel and user for populating the cache. -This directory may later contain other files of interacting -with the cache. - -The 'channel' works a bit like a datagram socket. Each 'write' is -passed as a whole to the cache for parsing and interpretation. -Each cache can treat the write requests differently, but it is -expected that a message written will contain: - - a key - - an expiry time - - a content. -with the intention that an item in the cache with the give key -should be create or updated to have the given content, and the -expiry time should be set on that item. - -Reading from a channel is a bit more interesting. When a cache -lookup fails, or when it succeeds but finds an entry that may soon -expire, a request is lodged for that cache item to be updated by -user-space. These requests appear in the channel file. - -Successive reads will return successive requests. -If there are no more requests to return, read will return EOF, but a -select or poll for read will block waiting for another request to be -added. - -Thus a user-space helper is likely to: - open the channel. - select for readable - read a request - write a response - loop. - -If it dies and needs to be restarted, any requests that have not been -answered will still appear in the file and will be read by the new -instance of the helper. - -Each cache should define a "cache_parse" method which takes a message -written from user-space and processes it. It should return an error -(which propagates back to the write syscall) or 0. - -Each cache should also define a "cache_request" method which -takes a cache item and encodes a request into the buffer -provided. - -Note: If a cache has no active readers on the channel, and has had not -active readers for more than 60 seconds, further requests will not be -added to the channel but instead all lookups that do not find a valid -entry will fail. This is partly for backward compatibility: The -previous nfs exports table was deemed to be authoritative and a -failed lookup meant a definite 'no'. - -request/response format ------------------------ - -While each cache is free to use it's own format for requests -and responses over channel, the following is recommended as -appropriate and support routines are available to help: -Each request or response record should be printable ASCII -with precisely one newline character which should be at the end. -Fields within the record should be separated by spaces, normally one. -If spaces, newlines, or nul characters are needed in a field they -much be quoted. two mechanisms are available: -1/ If a field begins '\x' then it must contain an even number of - hex digits, and pairs of these digits provide the bytes in the - field. -2/ otherwise a \ in the field must be followed by 3 octal digits - which give the code for a byte. Other characters are treated - as them selves. At the very least, space, newline, nul, and - '\' must be quoted in this way. -- cgit v1.2.3 From d396c5f158547e50c2b78bc984cb4a72d76e969b Mon Sep 17 00:00:00 2001 From: "J.
