2010-10-06mac80211: delete AddBA response timerJohannes Berg1-0/+2
We never delete the addBA response timer, which is typically fine, but if the station it belongs to is deleted very quickly after starting the BA session, before the peer had a chance to reply, the timer may fire after the station struct has been freed already. Therefore, we need to delete the timer in a suitable spot -- best when the session is being stopped (which will happen even then) in which case the delete will be a no-op most of the time. I've reproduced the scenario and tested the fix.

This fixes a race pointed out by Dave Airlie where we don't take a buffer object about to be destroyed off the LRU lists properly. It also fixes a rare case where a buffer object could be destroyed in the middle of an accelerated eviction. The patch also adds a utility function that can be used to prematurely release GPU memory space usage of an object waiting to be destroyed. For example during eviction or swapout. The above mentioned commit didn't queue the buffer on the delayed destroy list under some rare circumstances. It also didn't completely honor the remove_all parameter.

However if during driver initialisation we were unable aquire linkage to the i915 driver enabling GPU turbo will lead to an oops on the first attempt to determine GPU busy status.

2010-10-05wait: using uninitialized member of wait queueEvgeny Kuznetsov1-0/+1
The "flags" member of "struct wait_queue_t" is used in several places in the kernel code without beeing initialized by init_wait(). "flags" is used in bitwise operations. If "flags" not initialized then unexpected behaviour may take place. Incorrect flags might used later in code. Added initialization of "wait_queue_t.flags" with zero value into "init_wait". Signed-off-by: Evgeny Kuznetsov <[email protected]> [ The bit we care about does end up being initialized by both prepare_to_wait() and add_to_wait_queue(), so this doesn't seem to cause actual bugs, but is definitely the right thing to do -Linus ] Signed-off-by: Linus Torvalds <[email protected]>
2010-10-05modules: Fix module_bug_list list corruption raceLinus Torvalds11-26/+14
With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

2010-10-05omap: iommu-load cam register before flushing the entryHari Kanigeri1-0/+1

2010-10-05xen: do not set xenstored_ready before xenbus_probe on hvmStefano Stabellini1-3/+6
Register_xenstore_notifier should guarantee that the caller gets notified even if xenstore is already up. Therefore we revert "do not notify callers from register_xenstore_notifier" and set xenstored_read at the right time for PV on HVM guests too. In fact in case of PV on HVM guests xenstored is ready only after the platform pci driver has completed the initialization, so do not set xenstored_ready before the call to xenbus_probe(). This patch fixes a shutdown_event watcher registration bug that causes "xm shutdown" not to work properly.
