This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic.

NVIDIA? :P It appears it's possible for a ctxprog to run even while a GPU exception is pending. The GF8 and up ctxprogs appear to have a small snippet of code which detects this, and stalls the ctxprog until it's been handled, which essentially looks like: if (r2 & 0x00008000) { r0 |= 0x80000000; while (r0 & 0x80000000) {} } I don't know of any way that flag would get cleared unless the driver intervenes (and indeed, in the cases I've seen the hang, nothing steps in to automagically clear it for us). This patch causes the driver to clear the flag during the PGRAPH IRQ handler.

While doing so, it destroys the operation fence, causing nouveau_fence_emit to crash. This patch fixes this bug by taking the fence object out of validate_op and creating it just before emit. The fence pointer is initialized to 0 and unref'ed unconditionally. In addition to fixing the bug, this prevents its reintroduction and simplifies the code.

The following patch adds support for PISMO modules found on ARM Ltd development platforms. These are MTD modules, and can have a selection of SRAM, flash or DOC devices as described by an on-board I2C EEPROM. We support SRAM and NOR flash devices only by registering appropriate conventional MTD platform devices as children of the 'pismo' device.

This allows to instruct the kernel to do relocations on user-selected addresses, since the relocation bounds checking relies on the request bounds. This can oops the kernel accidentally and is easily exploitable. This patch adds bound checking and alignment checking for ->offset and ->nr_dwords. It also makes some variables unsigned, which should have no effect, but prevents possible bounds checking problems.

Cisco reported on RHEL4 U6 and SAP reported on SLES9 SP4 and SLES10 SP2. We added these fixes on RHEL4 U6 and gave a private build to IBM and Cisco. Cisco and IBM tested it for more than 15 days and they reported that they did not see the issue so far. Before the fix, Cisco used to see the issue within 5 days. We generated a patch for SLES9 SP4 and SLES10 SP2 and submitted to Novell. Novell applied the patch and gave a test build to SAP. SAP tested and reported that the build is working properly. We also tested in our lab using the tools "dishogsync", which is IO stress tool and the tool was provided by Cisco. Issue1: File System going into read-only mode Root cause: The driver tends to not free the memory (FIB) when the management request exits prematurely. The accumulation of such un-freed memory causes the driver to fail to allocate anymore memory (FIB) and hence return 0x70000 value to the upper layer, which puts the file system into read only mode. Fix details: The fix makes sure to free the memory (FIB) even if the request exits prematurely hence ensuring the driver wouldn't run out of memory (FIBs). Issue2: False Raid Alert occurs When the Physical Drives and Logical drives are reported as deleted or added, even though there is no change done on the system Root cause: Driver IOCTLs is signaled with EINTR while waiting on response from the lower layers. Returning "EINTR" will never initiate internal retry. Fix details: The issue was fixed by replacing "EINTR" with "ERESTARTSYS" for mid-layer retries.

It is now not allowed to free up the block-request before cleanup and partial deallocation of the scsi-command. (Which is not so for none bidi commands) The right fix to this problem would be to make bidi command a first citizen by allocating a scsi_sdb pointer at scsi command just like cmd->prot_sdb. The bidi sdb should be allocated/deallocated as part of the get/put_command (Again like the prot_sdb) and the current decoupling of scsi_cmnd and blk-request should be kept. For now make sure scsi_release_buffers() is called before the call to blk_end_request_all() which might cause the suicide of the block requests. At best the leak of bidi buffers, at worse a crash, as there is a race between the existence of the bidi_request and the free of the associated bidi_sdb. The reason this was never hit before is because only OSD has the potential of doing asynchronous bidi commands. (So does bsg but it is never used) And OSD clients just happen to do all their bidi commands synchronously, up until recently.

These errors are caused both by bugs in the Gallium driver and by user-specified index buffers with out of bounds indices. By mmio-tracing the nVidia drivers, I found out how this is done. On DMA_VTX_PROTECTION, The nVidia driver reads the register 0x402000, always getting the value 4, and then writes 4 back to 0x402000. This patch adds that logic by reading 0x402000 and writing the same value back. It's unclear what should happen if the value read is not 4, and the current approach might not be the correct one. To test this, modify mesa/progs/trivial/vbo-drawrange.c, defining ELTOBJ to 1 and replacing indices with huge out of bounds integers. Without this patch, the GPU and/or kernel should lock up. With this patch, it should misrender as expected but not lock up. The errors are still logged since they are useful for development. This has been tested on NV49 and may not work on other cards. To find out how things work on other cards, run the aforementioned test using the blob with mmiotrace and grep for a read of the PGRAPH source register.

The TTM device release will try to evict anything in VRAM to GART memory, but this will fail since sgdma has already been taken down. This causes an infinite loop in kernel mode on module unload. It usually doesn't happen because there aren't any buffer on close. However, if the GPU is locked up, this condition is easily triggered. This patch fixes it in the simplest way possible by cleaning VRAM right before cleaning SGDMA memory.

In the current implementation the sysconfig value is read into _sysc_cache once and an actual update to the sysconfig register happens only if the new value paased is differnt from the one in _sysc_cache. _sysc_cache is updated only if _HWMOD_SYSCONFIG_LOADED is not set. This can lead to the follwing issue if off mode is enabled in modules which employs "always-retore" mechanism of context save and restore. a. The module sets the sysconfig register through omap_device_enable. Here _sysc_cache is updated with the value written to the sysconfig register and left. b. The power domain containig the module enters off mode and the module context is lost. c. The module in use becomes active and calls omap_device_enable to enable itself. Here a read of sysconfig register does not happen as _HWMOD_SYSCONFIG_LOADED flag is set. The value to be written to the sysconfig register will be same as the one written in step a. Since _sysc_cache reflects the previous written value an update of the sysconfig register does not happen. This means in modules which employs "always-restore" mechanism after off , the sysconfig regsiters will never get updated. This patch introduces a flag SYSC_NO_CACHE which if set ensures that the sysconfig register is always read into _sysc_cache before an update is attempted. This flags need to be set only by modules which does not do a context save but re-initializes the registers every time the module is accessed. This includes modules like i2c, smartreflex etc. Signed-off-by: Thara Gopinath [paul@pwsan.com: tweaked to apply on a different head, added flag comment] Signed-off-by: Paul Walmsley --- arch/arm/mach-omap2/omap_hwmod.c | 3 ++- arch/arm/plat-omap/include/plat/omap_hwmod.h | 1 + 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-omap2/omap_hwmod.c b/arch/arm/mach-omap2/omap_hwmod.c index d8c8545875b1..478ae585ca39 100644 --- a/arch/arm/mach-omap2/omap_hwmod.c +++ b/arch/arm/mach-omap2/omap_hwmod.c @@ -94,7 +94,8 @@ static int _update_sysc_cache(struct omap_hwmod *oh) oh->_sysc_cache = omap_hwmod_readl(oh, oh->sysconfig->sysc_offs); - oh->_int_flags |= _HWMOD_SYSCONFIG_LOADED; + if (!(oh->sysconfig->sysc_flags & SYSC_NO_CACHE)) + oh->_int_flags |= _HWMOD_SYSCONFIG_LOADED; return 0; } diff --git a/arch/arm/plat-omap/include/plat/omap_hwmod.h b/arch/arm/plat-omap/include/plat/omap_hwmod.h index 007935a921ea..33933256a226 100644 --- a/arch/arm/plat-omap/include/plat/omap_hwmod.h +++ b/arch/arm/plat-omap/include/plat/omap_hwmod.h @@ -227,6 +227,7 @@ struct omap_hwmod_ocp_if { #define SYSC_HAS_SIDLEMODE (1 << 5) #define SYSC_HAS_MIDLEMODE (1 << 6) #define SYSS_MISSING (1 << 7) +#define SYSC_NO_CACHE (1 << 8) /* XXX SW flag, belongs elsewhere */ /* omap_hwmod_sysconfig.clockact flags */ #define CLOCKACT_TEST_BOTH 0x0 -- cgit v1.2.3 From 6468e3b18777ecfffa6738e365896be9f17403f2 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 19 Jan 2010 17:30:52 -0700 Subject: OMAP3: clock: Remove unnecessarily .init initializers from OMAP3 clocks The first thing that omap2_init_clksel_parent() does is check for a non-zero .clksel field in the struct clk.

This patch doesn't break userspace, it detect "valid" old use of CB_COLOR[0-7]_FRAG & CB_COLOR[0-7]_TILE registers and overwritte the address these registers are pointing to with the one of the last color buffer. This workaround will work for old mesa & xf86-video-ati and any old user which did use similar register programming pattern as those (we expect that there is no others user of those ioctl except possibly a malicious one). This patch add a warning if it detects such usage, warning encourage people to update their mesa & xf86-video-ati. New userspace will submit proper relocation. Fix for xf86-video-ati / mesa (this kernel patch is enough to prevent abuse, fix for userspace are to set proper cs stream and avoid kernel warning) : http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=95d63e408cc88b6934bec84a0b1ef94dfe8bee7b http://cgit.freedesktop.org/mesa/mesa/commit/?id=46dc6fd3ed5ef96cda53641a97bc68c3bc104a9f Abusing this register to perform system ram memory is not easy, here is outline on how it could be achieve. First attacker must have access to the drm device and be able to submit command stream throught cs ioctl. Then attacker must build a proper command stream for r6xx/r7xx hw which will abuse the FRAG or TILE buffer to overwrite the GPU GART which is in VRAM. To achieve so attacker as to setup CB_COLOR[0-7]_FRAG or CB_COLOR[0-7]_TILE to point to the GPU GART, then it has to find a way to write predictable value into those buffer (with little cleverness i believe this can be done but this is an hard task). Once attacker have such program it can overwritte GPU GART to program GPU gart to point anywhere in system memory. It then can reusse same method as he used to reprogram GART to overwritte the system ram through the GART mapping. In the process the attacker has to be carefull to not overwritte any sensitive area of the GART table, like ring or IB gart entry as it will more then likely lead to GPU lockup. Bottom line is that i think it's very hard to use this flaw to get system ram access but in theory one can achieve so. Side note: I am not aware of anyone ever using the GPU as an attack vector, nevertheless we take great care in the opensource driver to try to detect and forbid malicious use of GPU. I don't think the closed source driver are as cautious as we are.

Before suspend and upon resume, it uses a weak function read_persistent_clock() to determine the amount of time that elapsed during suspend. This function was not implemented on OMAP, so from the timekeeping subsystem perspective (and thus userspace as well) it appeared that no time elapsed during suspend. This patch uses the 32k sync timer as a the persistent clock. NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so more than one wrapping of the 32k sync timer during suspend may cause problems. Also note there are not interrupts when the 32k sync timer wraps, so something else has to be done.

Unequivocally setting the bit in nodes_parsed is insufficient since existing code, such as acpi_get_nodes(), assumes all nodes in the map have online address ranges. In fact, all code using nodes_parsed assumes such nodes represent an address range of online memory. nodes_possible_map is created by unioning nodes_parsed and cpu_nodes_parsed; the former represents nodes with online memory and the latter represents memoryless nodes.

However, leave it as is in the interest of keeping the pure bug fix patch small. ] Signed-off-by: David Rientjes Tested-by: Haicheng Li LKML-Reference: Cc: Signed-off-by: H.

Commit d1c84f79a6ba992dc01e312c44a21496303874d6 leads to a regression when microcode_amd.c is compiled into the kernel. It causes a big boot delay because the firmware is not available. See http://marc.info/?l=linux-kernel&m=126267290920060 It also renders the reload sysfs attribute useless. Fixing this is too intrusive for an -rc5 kernel. Thus I'd like to restore the microcode loading behaviour of kernel 2.6.32. CC: Gene Heskett Signed-off-by: Andreas Herrmann LKML-Reference: <20100122203456.GB13792@alberich.amd.com> Signed-off-by: H.

However, we then use the next pointer we stored, which is not guaranteed to be valid. This was apparently the cause of some Nouveau oopses I experienced. This patch rewrites the function so that it keeps the reference to nentry until nentry itself is freed and we already got a reference to nentry->next. v2 updated by me according to Thomas Hellstrom's feedback. v3 proposed by Thomas Hellstrom. Commit comment updated by me. Both updates fixed minor efficiency/style issues only and all three versions should be correct.

This pin has to be also set to 1 for power-off to work. To power-off the rev. B1 machine, pin 8 has to be set to 1 and then set to 0 to do actual power-off. Tested on my DNS-323 rev.

The vcpu can pick up the IRR and inject the interrupt before setting the TMR, and perhaps even EOI it, causing incorrect behaviour. The race is really insignificant since it can only occur on the first interrupt (usually following interrupts will not change TMR), but it's better closed than open. Fixed by reordering setting the TMR vs IRR.

The hang is due to a recursive use of the aer_inject lock. The aer_inject() routine grabs the lock while processing the error and then calls pci_read_config_dword to read the masks. The pci_read_config_dword routine is earlier overridden by pci_read_aer, which among other things, grabs the aer_inject lock. Fixed by moving the pci_read_config_dword calls to read the masks to before the lock is taken.

This is caused by the checking of the pid in the buffer. If the pid is negative, it still references the cmdline cache array, which could point to an invalid address. The simple fix is to test for negative PIDs.

When the kernel is stopped by kgdb inside code which holds watchdog_lock then kgdb dead locks in clocksource_resume_watchdog(). clocksource_resume_watchdog() is called from kbdg via clocksource_touch_watchdog() to avoid that the clock source watchdog marks TSC unstable after the kernel has been stopped. Solve this by replacing spin_lock with a spin_trylock and just return in case the lock is held. Not resetting the watchdog might result in TSC becoming marked unstable, but that's an acceptable penalty for using kgdb. The timekeeping is anyway easily screwed up by kgdb when the system uses either jiffies or a clock source which wraps in short intervals (e.g. pm_timer wraps about every 4.6s), so we really do not have to worry about that occasional TSC marked unstable side effect. The second caller of clocksource_resume_watchdog() is clocksource_resume(). The trylock is safe here as well because the system is UP at this point, interrupts are disabled and nothing else can hold watchdog_lock().

However, the sum of the bare minimum ROM plus all descriptors (from firewire-core, from firewire-net, from userspace) must not exceed 256 quadlets. Otherwise, the bounds of a statically allocated buffer will be overwritten. If the kernel survives that, firewire-core will subsequently be unable to parse the local node's config ROM. (Note, userspace drivers can add descriptors only through device files of local nodes.

We need to copy such payloads for each registered userspace client and free the copies according to the lifetime rules of non-FCP client request resources. (This could possibly be optimized by reference counts instead of copies.) The presently only kernelspace driver which listens for FCP requests, firedtv, was not affected because it already copies FCP frames into an own buffer before returning to firewire-core's FCP handler dispatcher.

There are two types of reads from the ring buffer. One is a consuming read which will consume the entry that was read and the next read will be the entry that follows. The other is an iterator that will let the user read the contents of the ring buffer without modifying it. When an iterator is allocated, writes to the ring buffer are disabled to protect the iterator. The problem exists when consuming reads happen while an iterator is allocated. Specifically, the kind of read that swaps out an entire page (used by splice) and replaces it with a new read. If the iterator is on the page that is swapped out, then the next read may read from this swapped out page and return garbage. This patch adds a check when reading the iterator to make sure that the iterator contents are still valid. If a consuming read has taken place, the iterator is reset.

In particular, the intel GPU object mapping code wants to be able to do a certain amount of own internal memory management by automatically shrinking the address space when memory starts getting tight. This allows it to dynamically use different memory allocation policies on a per-allocation basis, rather than depend on the (static) address space gfp policy. The actual new function is a one-liner, but re-organizing the helper functions to the point where you can do this with a single line of code is what most of the patch is all about.

With luck, this merely prevents video reception. With only a little less luck, the machine crashes. We use the same workaround here as with TSB43AB22/A: Switch off the dual buffer capability flag and use packet-per-buffer IR DMA instead. Another possible workaround would be to limit the coherent DMA mask to 31 bits. In Linux 2.6.33, this change serves effectively only as documentation since dual buffer mode is not used for any controller anymore. But somebody might want to re-enable it in the future to make use of features of dual buffer DMA that are not available in packet-per-buffer mode. In Linux 2.6.32 and older, this update is vital for anyone with this controller, more than 2 GB RAM, a 64 bit kernel, and FireWire video or audio applications.

By not enabling NORETRY by default these paths can run the shrinker and take memory from the system (but not from our own inactive lists because our shrinker can not run whilst we hold the struct mutex) and this may allow the system to survive a little longer whilst our drivers consume all available memory.

Patch Changelog: Version 2 - simplified method by using 'expr' for 'substr' and making it work with dash once again Version 1 - Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error of "make clean" - Consider more cases of the VMLINUX_LOAD_ADDRESS Version 0 - initial release Signed-off-by: Alexander Clouter Acked-by: Wu Zhangjin Patchwork: http://patchwork.linux-mips.org/patch/861/ Signed-off-by: Ralf Baechle --- arch/mips/boot/compressed/Makefile | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/arch/mips/boot/compressed/Makefile b/arch/mips/boot/compressed/Makefile index bdcfd49f022d..9df903d714d7 100644 --- a/arch/mips/boot/compressed/Makefile +++ b/arch/mips/boot/compressed/Makefile @@ -14,8 +14,11 @@ # compressed kernel load addr: VMLINUZ_LOAD_ADDRESS > VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE VMLINUX_SIZE := $(shell wc -c $(objtree)/$(KBUILD_IMAGE) 2>/dev/null | cut -d' ' -f1) -VMLINUX_SIZE := $(shell [ -n "$(VMLINUX_SIZE)" ] && echo $$(($(VMLINUX_SIZE) + (65536 - $(VMLINUX_SIZE) % 65536)))) -VMLINUZ_LOAD_ADDRESS := 0x$(shell [ -n "$(VMLINUX_SIZE)" ] && printf %x $$(($(VMLINUX_LOAD_ADDRESS) + $(VMLINUX_SIZE)))) +VMLINUX_SIZE := $(shell [ -n "$(VMLINUX_SIZE)" ] && echo -n $$(($(VMLINUX_SIZE) + (65536 - $(VMLINUX_SIZE) % 65536)))) +# VMLINUZ_LOAD_ADDRESS = concat "high32 of VMLINUX_LOAD_ADDRESS" and "(low32 of VMLINUX_LOAD_ADDRESS) + VMLINUX_SIZE" +HIGH32 := $(shell A=$(VMLINUX_LOAD_ADDRESS); [ $${\#A} -gt 10 ] && expr substr "$(VMLINUX_LOAD_ADDRESS)" 3 $$(($${\#A} - 10))) +LOW32 := $(shell [ -n "$(HIGH32)" ] && A=11 || A=3; expr substr "$(VMLINUX_LOAD_ADDRESS)" $${A} 8) +VMLINUZ_LOAD_ADDRESS := 0x$(shell [ -n "$(VMLINUX_SIZE)" -a -n "$(LOW32)" ] && printf "$(HIGH32)%08x" $$(($(VMLINUX_SIZE) + 0x$(LOW32)))) # set the default size of the mallocing area for decompressing BOOT_HEAP_SIZE := 0x400000 -- cgit v1.2.3 From 59dfa2fcaecc39fb88bfa196cb15adca7146867a Mon Sep 17 00:00:00 2001 From: David VomLehn Date: Wed, 23 Dec 2009 17:34:46 -0800 Subject: MIPS: PowerTV: Streamline access to platform device registers Pre-compute addresses for the basic ASIC registers. This speeds up access and allows memory for unused configurations to be freed. In addition, uninitialized register addresses will be returned as NULL to catch bad usage quickly.

Using a greater number without IRQ sharing requires reading platform-specific registers. On such platforms, reading the IntCtl register to determine which interrupt corresponds to a timer interrupt will not work. On MIPSR2 systems there is a solution - the TI bit in the Cause register, specifically indicates that a timer interrupt has occured.

This can save considerable CPU because all future writes to the file go through uncompressed. But some files are both very large and have mixed data stored in them. In that case, we want to add the ability to always try compressing data before writing it. This commit adds mount -o compress-force. A later commit will add a new inode flag that does the same thing.

It doesn't just flush the old executable environment, it also starts up the new one. Which is very inconvenient for things like setting up the new personality, because we want the new personality to affect the starting of the new environment, but at the same time we do _not_ want the new personality to take effect if flushing the old one fails. As a result, the x86-64 '32-bit' personality is actually done using this insane "I'm going to change the ABI, but I haven't done it yet" bit (TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the personality, but just the "pending" bit, so that "flush_thread()" can do the actual personality magic. This patch in no way changes any of that insanity, but it does split the 'flush_old_exec()' function up into a preparatory part that can fail (still called flush_old_exec()), and a new part that will actually set up the new exec environment (setup_new_exec()). All callers are changed to trivially comply with the new world order. Signed-off-by: H.

Fix that in the most straightforward way (which, considering the overheads of alternative approaches, is Mel's preference): the right migratetype is already in page_private(page), but free_pcppages_bulk() wasn't using it. How did this bug show up? As a 20% slowdown in my tmpfs loop kbuild swapping tests, on PowerMac G5 with SLUB allocator. Bisecting to that commit was easy, but explaining the magnitude of the slowdown not easy. The same effect appears, but much less markedly, with SLAB, and even less markedly on other machines (the PowerMac divides into fewer zones than x86, I think that may be a factor). We guess that lumpy reclaim of short-lived high-order pages is implicated in some way, and probably this bug has been tickling a poor decision somewhere in page reclaim. But instrumentation hasn't told me much, I've run out of time and imagination to determine exactly what's going on, and shouldn't hold up the fix any longer: it's valid, and might even fix other misbehaviours.

The hw_breakpoint_handler() now consumes the hw breakpoints that were previously set by kgdb arch specific code. In order for kgdb to work in conjunction with this core API change, kgdb must use some of the low level functions of the hw_breakpoint API to install, uninstall, and deal with hw breakpoint reservations. The kgdb core required a change to call kgdb_disable_hw_debug anytime a slave cpu enters kgdb_wait() in order to keep all the hw breakpoints in sync as well as to prevent hitting a hw breakpoint while kgdb is active. During the architecture specific initialization of kgdb, it will pre-allocate 4 disabled (struct perf event **) structures. Kgdb will use these to manage the capabilities for the 4 hw breakpoint registers, per cpu. Right now the hw_breakpoint API does not have a way to ask how many breakpoints are available, on each CPU so it is possible that the install of a breakpoint might fail when kgdb restores the system to the run state. The intent of this patch is to first get the basic functionality of hw breakpoints working and leave it to the person debugging the kernel to understand what hw breakpoints are in use and what restrictions have been imposed as a result. Breakpoint constraints will be dealt with in a future patch. While atomic, the x86 specific kgdb code will call arch_uninstall_hw_breakpoint() and arch_install_hw_breakpoint() to manage the cpu specific hw breakpoints. The net result of these changes allow kgdb to use the same pool of hw_breakpoints that are used by the perf event API, but neither knows about future reservations for the available hw breakpoint slots.

The kernel debugger cannot use any mutex_lock() calls because it can start the kernel running from an invalid context. A mutex free version of the reservation API needed to get created for the kernel debugger to safely update hw breakpoint reservations. The possibility for a breakpoint reservation to be concurrently processed at the time that kgdb interrupts the system is improbable. Should this corner case occur the end user is warned, and the kernel debugger will prohibit updating the hardware breakpoint reservations. Any time the kernel debugger reserves a hardware breakpoint it will be a system wide reservation.

The above commit changes agp_amd64_init() not to do anything if gart_iommu_aperture is not zero. If GART iommu calls agp_amd64_init(), we need to skip agp_amd64_init() when it's called later via module_init. The problem is that gart_iommu_init() calls agp_amd64_init() with not zero gart_iommu_aperture so agp_amd64_init() is never initialized. When gart_iommu_init() calls agp_amd64_init(), agp should be always initialized.

The LVTMA encoder requires the second digital encoder, all others can use any encoder at all. This fixes the digital encoder selection logic to enable LVDS/DP combos to work okay. V2: fix silly addition of connector dig_block and cleanup the other places in the code that pick the encoder. V3: rename to dig_encoder and clean up further - also fix the picking algorithm. tested on Lenovo W500 + desktop 3650 cards.

Should partialy or totaly fix: https://bugzilla.redhat.com/show_bug.cgi?id=553279 V2 failing blit initialization is not fatal, fallback to memcpy when this happen V3 init blit before startup as we pin in startup, remove duplicate code (this one was actualy tested unlike V2) Signed-off-by: Jerome Glisse Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/r600.c | 54 +++++++++++++++++----------------- drivers/gpu/drm/radeon/r600_blit_kms.c | 7 +++-- drivers/gpu/drm/radeon/radeon.h | 1 + drivers/gpu/drm/radeon/rv770.c | 31 ++++++++++--------- 4 files changed, 48 insertions(+), 45 deletions(-) diff --git a/drivers/gpu/drm/radeon/r600.c b/drivers/gpu/drm/radeon/r600.c index d0bd117a463a..b833b4b97162 100644 --- a/drivers/gpu/drm/radeon/r600.c +++ b/drivers/gpu/drm/radeon/r600.c @@ -1788,23 +1788,24 @@ void r600_fence_ring_emit(struct radeon_device *rdev, radeon_ring_write(rdev, RB_INT_STAT);

In this configuration kgdb will report a softlock warning message on resuming or detaching from a debug session. Sequence of events in the problem case: 1) "cpu sched clock" and "hardware time" are at 100 sec prior to a call to kgdb_handle_exception() 2) Debugger waits in kgdb_handle_exception() for 80 sec and on exit the following is called ... touch_softlockup_watchdog() --> __raw_get_cpu_var(touch_timestamp) = 0; 3) "cpu sched clock" = 100s (it was not updated, because the interrupt was disabled in kgdb) but the "hardware time" = 180 sec 4) The first timer interrupt after resuming from kgdb_handle_exception updates the watchdog from the "cpu sched clock" update_process_times() { ... run_local_timers() --> softlockup_tick() --> check (touch_timestamp == 0) (it is "YES" here, we have set "touch_timestamp = 0" at kgdb) --> __touch_softlockup_watchdog() ***(A)--> reset "touch_timestamp" to "get_timestamp()" (Here, the "touch_timestamp" will still be set to 100s.) ... scheduler_tick() ***(B)--> sched_clock_tick() (update "cpu sched clock" to "hardware time" = 180s) ... } 5) The Second timer interrupt handler appears to have a large jump and trips the softlockup warning. update_process_times() { ... run_local_timers() --> softlockup_tick() --> "cpu sched clock" - "touch_timestamp" = 180s-100s > 60s --> printk "soft lockup error messages" ... } note: ***(A) reset "touch_timestamp" to "get_timestamp(this_cpu)" Why is "touch_timestamp" 100 sec, instead of 180 sec? When CONFIG_HAVE_UNSTABLE_SCHED_CLOCK is set, the call trace of get_timestamp() is: get_timestamp(this_cpu) -->cpu_clock(this_cpu) -->sched_clock_cpu(this_cpu) -->__update_sched_clock(sched_clock_data, now) The __update_sched_clock() function uses the GTOD tick value to create a window to normalize the "now" values. So if "now" value is too big for sched_clock_data, it will be ignored. The fix is to invoke sched_clock_tick() to update "cpu sched clock" in order to recover from this state. This is done by introducing the function touch_softlockup_watchdog_sync(). This allows kgdb to request that the sched clock is updated when the watchdog thread runs the first time after a resume from kgdb.

There is another similar race: Between said tasklet and fwnet_close, i.e. at ifdown. However, that race is much less likely to occur in practice and shall be fixed in a separate update.

I am reposting it with more test results. This patch does two things. - Do not idle on async queues. - It also changes the write queue depth CFQ drives (cfq_may_dispatch()). Currently, we seem to driving queue depth of 1 always for WRITES. This is true even if there is only one write queue in the system and all the logic of infinite queue depth in case of single busy queue as well as slowly increasing queue depth based on last delayed sync request does not seem to be kicking in at all. This patch will allow deeper WRITE queue depths (subjected to the other WRITE queue depth contstraints like cfq_quantum and last delayed sync request). Shaohua Li had reported getting more out of his SSD. For me, I have got one Lun exported from an HP EVA and when pure buffered writes are on, I can get more out of the system. Following are test results of pure buffered writes (with end_fsync=1) with vanilla and patched kernel. These results are average of 3 sets of run with increasing number of threads. AVERAGE[bufwfs][vanilla] ------- job Set NR ReadBW(KB/s) MaxClat(us) WriteBW(KB/s) MaxClat(us) --- --- -- ------------ ----------- ------------- ----------- bufwfs 3 1 0 0 95349 474141 bufwfs 3 2 0 0 100282 806926 bufwfs 3 4 0 0 109989 2.7301e+06 bufwfs 3 8 0 0 116642 3762231 bufwfs 3 16 0 0 118230 6902970 AVERAGE[bufwfs] [patched kernel] ------- bufwfs 3 1 0 0 270722 404352 bufwfs 3 2 0 0 206770 1.06552e+06 bufwfs 3 4 0 0 195277 1.62283e+06 bufwfs 3 8 0 0 260960 2.62979e+06 bufwfs 3 16 0 0 299260 1.70731e+06 I also ran buffered writes along with some sequential reads and some buffered reads going on in the system on a SATA disk because the potential risk could be that we should not be driving queue depth higher in presence of sync IO going to keep the max clat low.

That made sense from a technical standpoint, but when we then also combined it with the actual personality setting going in between flush_old_exec() and setup_new_exec(), it needs to be a bit more careful. In particular, we need to make sure that we really flush the old personality bits in the 'flush' stage, rather than later in the 'setup' stage, since otherwise we might be flushing the _new_ personality state that we're just setting up. So this moves the flags and personality flushing (and 'flush_thread()', which is the arch-specific function that generally resets lazy FP state etc) of the old process into flush_old_exec(), so that it doesn't affect any state that execve() is setting up for the new process environment. This was reported by Michal Simek as breaking his Microblaze qemu environment.

It did not use RCU primitives, and also the union of free_list and rcu_head is obviously wrong (because free_list is indeed the list we are RCU walking). While we are there, remove a couple of unused fields from an earlier iteration. These APIs aren't actually used anywhere, because of problems with the XFS conversion. Christoph has now verified that the problems are solved with these patches. Also it is an exported interface, so I think it will be good to be merged now (and Christoph wants to get the XFS changes into their local tree).

We previously don't free up per-CPU maps until all its addresses have been used and freed. So fragmented blocks could fill up vmalloc space even if they actually had no active vmap regions within them. Add some logic to allow all CPUs to have these blocks purged in the case of failure to allocate a new vm area, and also put some logic to trim such blocks of a current CPU if we hit them in the allocation path (so as to avoid a large build up of them). Christoph reported some vmap allocation failures when using the per CPU vmap APIs in XFS, which cannot be reproduced after this patch and the previous bug fix.

With IDR_BITS of 6, it grows to three layers when id 4096 is first allocated. When that happens, idr wraps incorrectly and searches the idr array ignoring the high bits. The following test code from Eric demonstrates the bug nicely. #include #include #include static DEFINE_IDR(test_idr); int init_module(void) { int ret, forty95, forty96; void *addr; /* add 2 entries both with 4095 as the start address */ again1: if (!idr_pre_get(&test_idr, GFP_KERNEL)) return -ENOMEM; ret = idr_get_new_above(&test_idr, (void *)4095, 4095, &forty95); if (ret) { if (ret == -EAGAIN) goto again1; return ret; } if (forty95 != 4095) printk(KERN_ERR "hmmm, forty95=%d\n", forty95); again2: if (!idr_pre_get(&test_idr, GFP_KERNEL)) return -ENOMEM; ret = idr_get_new_above(&test_idr, (void *)4096, 4095, &forty96); if (ret) { if (ret == -EAGAIN) goto again2; return ret; } if (forty96 != 4096) printk(KERN_ERR "hmmm, forty96=%d\n", forty96); /* try to find the 2 entries, noticing that 4096 broke */ addr = idr_find(&test_idr, forty95); if ((int)addr != forty95) printk(KERN_ERR "hmmm, after find forty95=%d addr=%d\n", forty95, (int)addr); addr = idr_find(&test_idr, forty96); if ((int)addr != forty96) printk(KERN_ERR "hmmm, after find forty96=%d addr=%d\n", forty96, (int)addr); /* really weird, the entry which should be at 4096 is actually at 0!! */ addr = idr_find(&test_idr, 0); if ((int)addr) printk(KERN_ERR "found an entry at id=0 for addr=%d\n", (int)addr); idr_remove(&test_idr, forty95); idr_remove(&test_idr, forty96); return 0; } void cleanup_module(void) { } MODULE_AUTHOR("Eric Paris "); MODULE_DESCRIPTION("Simple idr test"); MODULE_LICENSE("GPL"); This happens because when sub_alloc() back tracks it doesn't always do it step-by-step while the over-the-limit detection assumes step-by-step backtracking. The logic in sub_alloc() looks like the following. restart: clear pa[top level + 1] for end cond detection l = top level while (true) { search for empty slot at this level if (not found) { push id to the next possible value l++ A: if (pa[l] is clear) failed, return asking caller to grow the tree if (going up 1 level gives more slots to search) continue the while loop above with the incremented l else C: goto restart } adjust id accordingly to the found slot if (l == 0) return found id; create lower level if not there yet record pa[l] and l-- } Test A is the fail exit condition but this assumes that failure is propagated upwared one level at a time but the B optimization path breaks the assumption and restarts the whole thing with a start value which is above the possible limit with the current layers. sub_alloc() assumes the start id value is inside the limit when called and test A is the only exit condition check, so it ends up searching for empty slot while ignoring high set bit. So, for 4095->4096 test, level0 search fails but pa[1] contains a valid pointer. However, going up 1 level wouldn't give any more empty slot so it takes C and when the whole thing restarts nobody notices the high bit set beyond the top level. This patch fixes the bug by changing the fail exit condition check to full id limit check.

So the right steps should be: flush_dcache_page(page); kmap_atomic(page); write to page; kunmap_atomic(page); flush_dcache_page(page); More precisely, we might create two new APIs flush_dcache_user_page and flush_dcache_kern_page to replace the two flush_dcache_page accordingly. Here is a snippet tested on omap2430 with VIPT cache, and I think it is not ARM-specific: int val = 0x11111111; fd = open("abc", O_RDWR); addr = mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); *(addr+0) = 0x44444444; tmp = *(addr+0); *(addr+1) = 0x77777777; write(fd, &val, sizeof(int)); close(fd); The results are not always 0x11111111 0x77777777 at the beginning as expected.

If a node were to get an ast for an upconvert request, followed immediately by a bast, there is a small window where the fs may downconvert the lock before the process requesting the upconvert is able to take the lock. This patch adds a new flag to indicate that the upconvert is still in progress and that the dc thread should not downconvert it right now.

Upon receiving the AST for the cancel convert, it will re-process the lock resource to determine whether it needs downconverting. Say, the up was from PR to EX and the BAST was for EX. After the cancel convert, it will need to downconvert to NL. However, if the node was originally upconverting from NL to EX, then there would be no reason to downconvert (assuming the same message sequence). This patch makes dlmglue consider the possibility that the current lock level is already compatible and that downconverting is not required. Joel Becker assisted in fixing this issue.

If the futex is created in a temporary file in an ext3 file system, this bug causes the file's inode to become an "undead" orphan, which causes an oops from a BUG_ON() in ext3_put_super() when the file system is unmounted. glibc's test suite is known to trigger this, see . The bug is a regression from 2.6.28-git3, namely Peter Zijlstra's 38d47c1b7075bd7ec3881141bb3629da58f88dab "[PATCH] futex: rely on get_user_pages() for shared futexes". That commit made get_futex_key() also increment the reference count of the futex key, and updated its callers to decrement the key's reference count before returning. Unfortunately the normal exit path in futex_lock_pi() wasn't corrected: the reference count is incremented by get_futex_key() and queue_lock(), but the normal exit path only decrements once, via unqueue_me_pi(). The fix is to put_futex_key() after unqueue_me_pi(), since 2.6.31 this is easily done by 'goto out_put_key' rather than 'goto out'.

When a malicious or just sloppy programmed user space application sets the futex value to 0 e.g. by calling pthread_mutex_init(), then the futex can be acquired again. A new waiter manages to enqueue itself on the pi_state w/o damage, but on unlock the kernel dereferences pi_state->owner and oopses. Prevent this by checking pi_state->owner in the unlock path. If pi_state->owner is not current we know that user space manipulated the futex value. Ignore the mess and return -EINVAL. This catches the above case and also the case where a task hijacks the futex by setting the tid value and then tries to unlock it.

Now, while it is correct that we should be expecting the ref, I see no reason why we have to BUG. After all, we are freeing up the lock and clearing the ref.

But BUG_ON() should be called by the wrong code, not user's operation, so I think it is a bug of btrfs. This patch fixes it.

That is because we were doing all this extra work to read in the file extent outside of the transaction, however in the random io case this ends up hurting us because the file extents are not there to begin with. So axe this logic, since we end up reading in the file extent when we go to update it anyway.

This implements the same D-cache flushing logic for r8a66597-hcd as Catalin's isp1760 (http://patchwork.kernel.org/patch/76391/) change, with the same note applying here as well: When the HDC driver writes the data to the transfer buffers it pollutes the D-cache (unlike DMA drivers where the device writes the data). If the corresponding pages get mapped into user space, there are no additional cache flushing operations performed and this causes random user space faults on architectures with separate I and D caches (Harvard) or those with aliasing D-cache.

This means that at least the part of ima which does this allocation (the allocation is filled with information later) should before any inodes are created. To accomplish this we split the ima initialization routine placing the kmem cache allocator inside a security_initcall() function. Since this makes use of radix trees we also need to make sure that is initialized before security_initcall().

It turns out that we really cannot hold 'tty->ctrl_lock' over calling __f_setown, because not only did that cause problems with interrupt disables (which the second commit fixed), it also causes a potential ABBA deadlock due to lock ordering. Thanks to Tetsuo Handa for following up on the issue, and running lockdep to show the problem. It goes roughly like this: - f_getown gets filp->f_owner.lock for reading without interrupts disabled, so an interrupt that happens while that lock is held can cause a lockdep chain from f_owner.lock -> sighand->siglock. - at the same time, the tty->ctrl_lock -> f_owner.lock chain that commit 703625118069 introduced, together with the pre-existing sighand->siglock -> tty->ctrl_lock chain means that we have a lock dependency the other way too. So instead of extending tty->ctrl_lock over the whole __f_setown() call, we now just take a reference to the 'pid' structure while holding the lock, and then release it after having done the __f_setown. That still guarantees that 'struct pid' won't go away from under us, which is all we really ever needed.

This wasn't a problem previously but it now triggers a BUG_ON in xics_set_cpu_priority() because os_cppr->index isn't 0. Fix this problem by setting the index on the CPPR stack to 0 before calling xics_set_cpu_priority() in xics_teardown_cpu(). Also make it clear that we only want to set the priority when there's just one CPPR value in the stack, and enforce it by updating the value of os_cppr->stack[0] rather than os_cppr->stack[os_cppr->index].

In the former case, the ts field of the feed union of struct dmxdev_filter is used, in the latter case the sec field of the same union is used. The ts field is a struct list_head, and is currently initialized in the open() method of the demux device. When for a given demuxer a section filter is set up, the sec field is played with, thus if a PES filter needs to be set up after that the ts field will be corrupted, causing a kernel oops. This fix moves the list head initialization to dvb_dmxdev_pes_filter_set(), so that the ts field is properly initialized every time a PES filter is set up.

Bruce Fields" Date: Mon, 8 Feb 2010 13:42:26 -0500 Subject: Revert "nfsd4: fix error return when pseudoroot missing" Commit f39bde24b275ddc45d fixed the error return from PUTROOTFH in the case where there is no pseudofilesystem. This is really a case we shouldn't hit on a correctly configured server: in the absence of a root filehandle, there's no point accepting version 4 NFS rpc calls at all. But the shared responsibility between kernel and userspace here means the kernel on its own can't eliminate the possiblity of this happening. And we have indeed gotten this wrong in distro's, so new client-side mount code that attempts to negotiate v4 by default first has to work around this case. Therefore when commit f39bde24b275ddc45d arrived at roughly the same time as the new v4-default mount code, which explicitly checked only for the previous error, the result was previously fine mounts suddenly failing. We'll fix both sides for now: revert the error change, and make the client-side mount workaround more robust. Signed-off-by: J.

This code was written long ago when it was not possible to reshape a degraded array. Now it is so the current level of degraded-ness needs to be taken in to account. Also newly addded devices should only reduce degradedness if they are deemed to be in-sync. In particular, if you convert a RAID5 to a RAID6, and increase the number of devices at the same time, then the 5->6 conversion will make the array degraded so the current code will produce a wrong value for 'degraded' - "-1" to be precise. If the reshape runs to completion end_reshape will calculate a correct new value for 'degraded', but if a device fails during the reshape an incorrect decision might be made based on the incorrect value of "degraded". This patch is suitable for 2.6.32-stable and if they are still open, 2.6.31-stable and 2.6.30-stable as well.

As accessing some md attributes takes the same lock that is held while removing those attributes a deadlock can occur. This patch addresses 3 issues in md that could lead to this deadlock. Two relate to calling flush_scheduled_work while the lock is held. This is probably a bad idea in general and as we use schedule_work to delete various sysfs objects it is particularly bad. In one case flush_scheduled_work is called from md_alloc (called by md_probe) called from do_md_run which holds the lock. This call is only present to ensure that ->gendisk is set. However we can be sure that gendisk is always set (though possibly we couldn't when that code was originally written. This is because do_md_run is called in three different contexts: 1/ from md_ioctl. This requires that md_open has succeeded, and it fails if ->gendisk is not set. 2/ from writing a sysfs attribute. This can only happen if the mddev has been registered in sysfs which happens in md_alloc after ->gendisk has been set. 3/ from autorun_array which is only called by autorun_devices, which checks for ->gendisk to be set before calling autorun_array. So the call to md_probe in do_md_run can be removed, and the check on ->gendisk can also go. In the other case flush_scheduled_work is being called in do_md_stop, purportedly to wait for all md_delayed_delete calls (which delete the component rdevs) to complete. However there really isn't any need to wait for them - they have already been disconnected in all important ways. The third issue is that raid5->stop() removes some attribute names while the lock is held. There is already some infrastructure in place to delay attribute removal until after the lock is released (using schedule_work). So extend that infrastructure to remove the raid5_attrs_group. This does not address all lockdep issues related to the sysfs "s_active" lock. The rest can be address by splitting that lockdep context between symlinks and non-symlinks which hopefully will happen.

In this case, we emulate 64k pages with multiple 4k hash PTEs, however in hpte_need_flush() we incorrectly only mask the hardware page size from the address, instead of the logical page size. This causes things to go wrong when we later attempt to iterate through the hardware subpages of the logical page. This patch corrects the error. It has been tested on pSeries bare metal by Michael Neuling.

(ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdma_bind_addr, no device is associated with the rdma_cm_id. Fix this. It turns out that important apps such as Open MPI depend on rdma_bind_addr() NOT associating any RDMA device when binding to a loopback address. Open MPI is being updated to deal with this, but at least until a new Open MPI release is available, maintain the previous behavior: allow rdma_bind_addr() to succeed, but do not bind to a device.

So this one trys to list DPLL parameters for different output types, should potential fix clock issue seen on new Arrandale CPUs. This fixes DPLL setting failure on one 1920x1080 dual channel LVDS for Ironlake. Test has also been made on LVDS panels with smaller size and CRT/HDMI/DP ports for different monitors on their all supported modes. Update: - Change name of double LVDS to dual LVDS. - Fix SSC 120M reference clock to use the right range.

Before changing the status of a buffer with a pending write we will await upon a new flush for that buffer. So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson , forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.

This fixes a bug caused by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") and unmasked by fc63cf237078c86214abcb2ee9926d8ad289da9b ("exec: setup_arg_pages() fails to return errors"). This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg. 80K on 4K pages or 'ulimit -s 79') all processes will be killed before they start. This is particularly bad with 64K pages, where a ulimit below 1280K will kill every process. To test, do: 'ulimit -s 15; ls' before and after the patch is applied. Before it's applied, 'ls' should be killed. After the patch is applied, 'ls' should no longer be killed. A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE.

When a cycle is lost, the controller will send the packet in the next cycle, instead of terminating the entire DMA program. There are two reasons for this: * This behaviour is compatible with the old IEEE1394 stack. Old applications would not expect the DMA program to stop in this case. * Since the OHCI driver does not report any uncompleted packets, the context would stop silently; clients would not have any chance to detect and handle this error without a watchdog timer. Signed-off-by: Clemens Ladisch Pieter Palmers notes: "The reason I added this retry behavior to the old stack is because some cards now and then fail to send a packet (e.g. the o2micro card in my dell laptop). I couldn't figure out why exactly this happens, my best guess is that the card cannot fetch the payload data on time. This happens much more frequently when sending large packets, which leads me to suspect that there are some contention issues with the DMA that fills the transmit FIFO. In the old stack it was a pretty critical issue as it resulted in a freeze of the userspace application. The omission of a packet doesn't necessarily have to be an issue. E.g. in IEC61883 streams the DBC field can be used to detect discontinuities in the stream. So as long as the other side doesn't bail when no [packet] is present in a cycle, there is not really a problem. I'm not convinced though that retrying is the proper solution, but it is simple and effective for what it had to do. And I think there are no reasons not to do it this way. Userspace can still detect this by checking the cycle the descriptor was sent in."

This follows the parisc change to ensure that tracehook_signal_handler() is aware of when we are single-stepping in order to ptrace_notify() appropriately. While this was implemented for 32-bit SH, sh64 neglected to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code, resulting in ptrace_notify() never being called. As sh64 uses all of the other abstractions already, this simply plugs in the thread flag in the appropriate enable/disable paths and fixes up the tracehook notification accordingly. With this in place, sh64 is brought in line with what 32-bit is already doing.

The value of fattr->time_start is propagated to read_cache_jiffies by nfs_update_inode(). Subsequent calls to nfs_attribute_timeout() will then use a good time stamp when computing the attribute cache timeout, and squelch unneeded GETATTR calls. Since the direct I/O paths erroneously leave the inode's fattr->time_start field set to zero, read_cache_jiffies for that inode is set to zero after any direct read or write operation. This triggers an otw GETATTR or ACCESS call to update the file's attribute and access caches properly, even when the NFS READ or WRITE replies have usable post-op attributes. Make sure the direct read and write setup code performs the same fattr initialization as the cached I/O paths to prevent unnecessary GETATTR calls. This was likely introduced by commit 0e574af1 in 2.6.15, which appears to add new nfs_fattr_init() call sites in the cached read and write paths, but not in the equivalent places in fs/nfs/direct.c. A subsequent commit in the same series, 33801147, introduces the fattr->time_start field. Interestingly, the direct write reschedule path already has a call to nfs_fattr_init() in the right place.

'overhead_size' is the size of the various header structures used during communication. The first bug is the use of 'sizeof' with the pointer of a structure instead of the structure itself - resulting in the wrong size being computed. This is then used in a check to see if the payload (data_size) would be to large for the preallocated structure. Since the bug produces a smaller value for the overhead, it was possible for the structure to be breached. (Although the current users of the code do not currently send enough data to trigger this bug.) The second bug is that the 'overhead_size' value is used to compute how much of the preallocated space should be cleared before populating it with fresh data. This should have simply been 'sizeof(struct cn_msg)' not overhead_size. The fact that 'overhead_size' was computed incorrectly made this problem "less bad" - leaving only a pointer's worth of space at the end uncleared. Thus, this bug was never producing a bad result, but still needs to be fixed - especially now that the value is computed correctly.

Fix this by not changing the state of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end().

When recovery_complete() is executed between dm_rh_update_states() and dm_writes() in do_mirror(), bios are processed with the region state, DM_RH_NOSYNC. However, the region data is freed without checking its pending count when dm_rh_update_states() is called next time. When bios are finished by mirror_end_io(), __rh_lookup() in dm_rh_dec() returns NULL even though a valid return value are expected. Solution Remove the state change of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end(). We can remove the state change because: - If the region data has been released by dm_rh_update_states(), a new region data is created with the state of DM_RH_NOSYNC, and bios are processed according to the DM_RH_NOSYNC state. - If the region data has not been released by dm_rh_update_states(), a state of the region is DM_RH_RECOVERING and bios are put in the delayed_bio list. The flag change from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end() was added in the following commit: dm raid1: handle resync failures author Jonathan Brassow Thu, 12 Jul 2007 16:29:04 +0000 (17:29 +0100) http://git.kernel.org/linus/f44db678edcc6f4c2779ac43f63f0b9dfa28b724 Signed-off-by: Takahiro Yasui Reviewed-by: Mikulas Patocka Signed-off-by: Alasdair G Kergon --- drivers/md/dm-region-hash.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/md/dm-region-hash.c b/drivers/md/dm-region-hash.c index 5f19ceb6fe91..168bd38f5006 100644 --- a/drivers/md/dm-region-hash.c +++ b/drivers/md/dm-region-hash.c @@ -660,10 +660,9 @@ void dm_rh_recovery_end(struct dm_region *reg, int success) spin_lock_irq(&rh->region_lock); if (success) list_add(®->list, ®->rh->recovered_regions); - else { - reg->state = DM_RH_NOSYNC; + else list_add(®->list, ®->rh->failed_recovered_regions); - } + spin_unlock_irq(&rh->region_lock); rh->wakeup_workers(rh->context); -- cgit v1.2.3 From 9eef87da2a8ea4920e0d913ff977cac064b68ee0 Mon Sep 17 00:00:00 2001 From: Kiyoshi Ueda Date: Tue, 16 Feb 2010 18:43:01 +0000 Subject: dm mpath: fix stall when requeueing io This patch fixes the problem that system may stall if target's ->map_rq returns DM_MAPIO_REQUEUE in map_request(). E.g. stall happens on 1 CPU box when a dm-mpath device with queue_if_no_path bounces between all-paths-down and paths-up on I/O load. When target's ->map_rq returns DM_MAPIO_REQUEUE, map_request() requeues the request and returns to dm_request_fn(). Then, dm_request_fn() doesn't exit the I/O dispatching loop and continues processing the requeued request again. This map and requeue loop can be done with interrupt disabled, so 1 CPU system can be stalled if this situation happens. For example, commands below can stall my 1 CPU box within 1 minute or so: # dmsetup table mp mp: 0 2097152 multipath 1 queue_if_no_path 0 1 1 service-time 0 1 2 8:144 1 1 # while true; do dd if=/dev/mapper/mp of=/dev/null bs=1M count=100; done & # while true; do \ > dmsetup message mp 0 "fail_path 8:144" \ > dmsetup suspend --noflush mp \ > dmsetup resume mp \ > dmsetup message mp 0 "reinstate_path 8:144" \ > done To fix the problem above, this patch changes dm_request_fn() to exit the I/O dispatching loop once if a request is requeued in map_request().

Resulting in overly restrictive permissions on sysfs files. The fix is to simply modify the code so that it always executes when we update the sysfs attributes, as we did in 2.6.31 and earlier.

The transmitter should not be turned off before all characters have been transmitted. serial8250_tx_empty() was reporting that all characters were transmitted before they actually were. === Discovered in parallel with more testing and analysis by Kees Schoenmakers as follows: I ran into an NetMos 9835 serial pci board which behaves a little different than the standard. This type of expansion board is very common. "Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together with the "UART_LSR_THRE" bit when writing data to the device. The NetMos device does it slightly different I believe that the TEMT bit is coupled to the shift register. The problem is that after writing data to the device and very quickly after that one does call serial8250_tx_empty, it returns the wrong information. My patch makes the test more robust (and solves the problem) and it does not affect the already correct devices. Alan: We may yet need to quirk this but now we know which chips we have a way to do that should we find this breaks some other 8250 clone with dodgy THRE.
