2007-04-30rework pm_ops pm_disk_mode, kill misuseJohannes Berg11-64/+56
This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

2007-04-30Extend print_symbol capabilityRobert Peterson2-9/+27
Today's print_symbol function dumps a kernel symbol with printk. This patch extends the functionality of kallsyms.c so that the symbol lookup function may be used without the printk. This is useful for modules that want to dump symbols elsewhere, for example, to debugfs. I intend to use the new function call in the GFS2 file system (which will be a separate patch).

This is a corner case where less than MSS sized new data thingie is awaiting in the send queue. For F-RTO to work correctly, a new data segment must be sent at certain point or F-RTO cannot be used at all. RFC4138 allows overriding of Nagle at that point.

2007-04-30[XFRM]: Restrict upper layer information by bundle.Masahide NAKAMURA3-0/+71
On MIPv6 usage, XFRM sub policy is enabled. When main (IPsec) and sub (MIPv6) policy selectors have the same address set but different upper layer information (i.e. protocol number and its ports or type/code), multiple bundle should be created. However, currently we have issue to use the same bundle created for the first time with all flows covered by the case. It is useful for the bundle to have the upper layer information to be restructured correctly if it does not match with the flow. 1. Bundle was created by two policies Selector from another policy is added to xfrm_dst. If the flow does not match the selector, it goes to slow path to restructure new bundle by single policy. 2. Bundle was created by one policy Flow cache is added to xfrm_dst as originated one. If the flow does not match the cache, it goes to slow path to try searching another policy.

2007-04-30[TCP]: Catch skb with S+L bugs earlierIlpo Järvinen1-3/+1
SACKED_ACKED and LOST are mutually exclusive with SACK, thus having their sum larger than packets_out is bug with SACK. Eventually these bugs trigger traps in the tcp_clean_rtx_queue with SACK but it's much more informative to do this here. Non-SACK TCP, however, could get more than packets_out duplicate ACKs which each increment sacked_out, so it makes sense to do this kind of limitting for non-SACK TCP but not for SACK enabled one. Perhaps the author had the opposite in mind but did the logic accidently wrong way around? Anyway, the sacked_out incrementer code for non-SACK already deals this issue before calling sync_left_out so this trapping can be done unconditionally.

2007-04-30[PATCH] INET : IPV4 UDP lookups converted to a 2 pass algoEric Dumazet1-57/+114
Some people want to have many UDP sockets, binded to a single port but many different addresses. We currently hash all those sockets into a single chain. Processing of incoming packets is very expensive, because the whole chain must be examined to find the best match. I chose in this patch to hash UDP sockets with a hash function that take into account both their port number and address : This has a drawback because we need two lookups : one with a given address, one with a wildcard (null) address.

2007-04-30[BLOCK] Don't pin lots of memory in mempoolsJens Axboe6-40/+11
Currently we scale the mempool sizes depending on memory installed in the machine, except for the bio pool itself which sits at a fixed 256 entry pre-allocation. There's really no point in "optimizing" this OOM path, we just need enough preallocated to make progress. A single unit is enough, lets scale it down to 2 just to be on the safe side.

2007-04-30cfq-iosched: get rid of cfqq hashVasily Tarasov1-100/+67
cfq hash is no more necessary. We always can get cfqq from io context. cfq_get_io_context_noalloc() function is introduced, because we don't want to allocate cic on merging and checking may_queue. In order to identify sync queue we've used hash key = CFQ_KEY_ASYNC. Since hash is eliminated we need to use other criterion: sync flag for queue is added. In all places where we dig in rb_tree we're in current context, so no additional locking is required. Advantages of this patch: no additional memory for hash, no seeking in hash, code is cleaner. But it is necessary now to seek cic in per-ioc rbtree, but it is faster: - most processes work only with few devices - most systems have only few block devices - it is a rb-tree Signed-off-by: Vasily Tarasov <vtaras@openvz.org> Changes by me: - Merge into CFQ devel branch - Get rid of cfq_get_io_context_noalloc() - Fix various bugs with dereferencing cic->cfqq[] with offset other than 0 or 1. - Fix bug in cfqq setup, is_sync condition was reversed. - Fix bug where only bio_sync() is used, we need to check for a READ too Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-04-30[PATCH] cfq-iosched: speed up rbtree handlingJens Axboe1-14/+48
For cases where the rbtree is mainly used for sorting and min retrieval, a nice speedup of the rbtree code is to maintain a cache of the leftmost node in the tree. Also spotted in the CFS CPU scheduler code. Improved by Alan D. Brunelle <Alan.Brunelle@hp.com> by updating the leftmost hint in cfq_rb_first() if it isn't set, instead of only updating it on insert.

2007-04-30cfq-iosched: rework the whole round-robin list conceptJens Axboe1-238/+123
Drawing on some inspiration from the CFS CPU scheduler design, overhaul the pending cfq_queue concept list management. Currently CFQ uses a doubly linked list per priority level for sorting and service uses. Kill those lists and maintain an rbtree of cfq_queue's, sorted by when to service them. This unfortunately means that the ionice levels aren't as strong anymore, will work on improving those later. We only scale the slice time now, not the number of times we service. This means that latency is better (for all priority levels), but that the distinction between the highest and lower levels aren't as big.

2007-04-30cfq-iosched: development updateJens Axboe1-120/+261
- Implement logic for detecting cooperating processes, so we choose the best available queue whenever possible. - Improve residual slice time accounting. - Remove dead code: we no longer see async requests coming in on sync queues. That part was removed a long time ago. That means that we can also remove the difference between cfq_cfqq_sync() and cfq_cfqq_class_sync(), they are now indentical. And we can kill the on_dispatch array, just make it a counter. - Allow a process to go into the current list, if it hasn't been serviced in this scheduler tick yet. Possible future improvements including caching the cfqq lookup in cfq_close_cooperator(), so we don't have to look it up twice. cfq_get_best_queue() should just use that last decision instead of doing it again.

2007-04-30cfq-iosched: improve preemption for cooperating tasksJens Axboe1-6/+20
When testing the syslet async io approach, I discovered that CFQ sometimes didn't perform as well as expected. cfq_should_preempt() needs to better check for cooperating tasks, so fix that by allowing preemption of an equal priority queue if the recently queued request is as good a candidate for IO as the one we are currently waiting for.
