* [IPSEC] xfrm: Undo afinfo lock proliferationHerbert Xu2006-06-18
| | | | | | | | | | | | | | | | | | | The number of locks used to manage afinfo structures can easily be reduced down to one each for policy and state respectively. This is based on the observation that the write locks are only held by module insertion/removal which are very rare events so there is no need to further differentiate between the insertion of modules like ipv6 versus esp6. The removal of the read locks in xfrm4_policy.c/xfrm6_policy.c might look suspicious at first. However, after you realise that nobody ever takes the corresponding write lock you'll feel better :) As far as I can gather it's an attempt to guard against the removal of the corresponding modules. Since neither module can be unloaded at all we can leave it to whoever fixes up IPv6 unloading :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [TG3]: Add recovery logic when MMIOs are re-orderedMichael Chan2006-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add recovery logic when we suspect that the system is re-ordering MMIOs. Re-ordered MMIOs to the send mailbox can cause bogus tx completions and hit BUG_ON() in the tx completion path. tg3 already has logic to handle re-ordered MMIOs by flushing the MMIOs that must be strictly ordered (such as the send mailbox). Determining when to enable the flush is currently a manual process of adding known chipsets to a list. The new code replaces the BUG_ON() in the tx completion path with the call to tg3_tx_recover(). It will set the TG3_FLAG_MBOX_WRITE_REORDER flag and reset the chip later in the workqueue to recover and start flushing MMIOs to the mailbox. A message to report the problem will be printed. We will then decide whether or not to add the host bridge to the list of chipsets that do re-ordering. We may add some additional code later to print the host bridge's ID so that the user can report it more easily. The assumption that re-ordering can only happen on x86 systems is also removed.

* [PATCH] arm_timer: remove a racy and obsolete PF_EXITING checkOleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | arm_timer() checks PF_EXITING to prevent BUG_ON(->exit_state) in run_posix_cpu_timers(). However, for some reason it does so only for CPUCLOCK_PERTHREAD case (which is imho wrong). Also, this check is not reliable, PF_EXITING could be set on another cpu without any locks/barriers just after the check, so it can't prevent from attaching the timer to the exiting task. The previous patch makes this check unneeded. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] run_posix_cpu_timers: remove a bogus BUG_ON()Oleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | do_exit() clears ->it_##clock##_expires, but nothing prevents another cpu to attach the timer to exiting process after that. arm_timer() tries to protect against this race, but the check is racy. After exit_notify() does 'write_unlock_irq(&tasklist_lock)' and before do_exit() calls 'schedule() local timer interrupt can find tsk->exit_state != 0. If that state was EXIT_DEAD (or another cpu does sys_wait4) interrupted task has ->signal == NULL. At this moment exiting task has no pending cpu timers, they were cleanuped in __exit_signal()->posix_cpu_timers_exit{,_group}(), so we can just return from irq.

* [PATCH] check_process_timers: fix possible lockupOleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | If the local timer interrupt happens just after do_exit() sets PF_EXITING (and before it clears ->it_xxx_expires) run_posix_cpu_timers() will call check_process_timers() with tasklist_lock + ->siglock held and check_process_timers: t = tsk; do { .... do { t = next_thread(t); } while (unlikely(t->flags & PF_EXITING)); } while (t != tsk); the outer loop will never stop. Actually, the window is bigger. Another process can attach the timer after ->it_xxx_expires was cleared (see the next commit) and the 'if (PF_EXITING)' check in arm_timer() is racy (see the one after that).

* [PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger2006-06-17
| | | | | | | | | | | | | A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

* [PATCH] fix cdrom openJens Axboe2006-06-17
| | | | | | | | | | | | | | | | Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

* [PATCH] tmpfs: time granularity fix for [acm]time going backwardsRobin H. Johnson2006-06-12
| | | | | | | | | | | | | | | | | | | | | | | | I noticed a strange behavior in a tmpfs file system the other day, while building packages - occasionally, and seemingly at random, make decided to rebuild a target. However, only on tmpfs. A file would be created, and if checked, it had a sub-second timestamp. However, after an utimes related call where sub-seconds should be set, they were zeroed instead. In the case that a file was created, and utimes(...,NULL) was used on it in the same second, the timestamp on the file moved backwards. After some digging, I found that this was being caused by tmpfs not having a time granularity set, thus inheriting the default 1 second granularity. Hugh adds: yes, we missed tmpfs when the s_time_gran mods went into 2.6.11. Unfortunately, the granularity of CURRENT_TIME, often used in filesystems, does not match the default granularity set by alloc_super. A few more such discrepancies have been found, but this is the most important to fix now. Signed-off-by: Robin H.
