2009-12-19fix more leaks in audit_tree.c tag_chunk()Al Viro
Several leaks in audit_tree didn't get caught by commit 318b6d3d7ddbcad3d6867e630711b8a705d873d7, including the leak on normal exit in case of multiple rules refering to the same chunk. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-12-19fix braindamage in audit_tree.c untag_chunk()Al Viro
... aka "Al had badly fscked up when writing that thing and nobody noticed until Eric had fixed leaks that used to mask the breakage". The function essentially creates a copy of old array sans one element and replaces the references to elements of original (they are on cyclic lists) with those to corresponding elements of new one. After that the old one is fair game for freeing. First of all, there's a dumb braino: when we get to list_replace_init we use indices for wrong arrays - position in new one with the old array and vice versa. Another bug is more subtle - termination condition is wrong if the element to be excluded happens to be the last one. We shouldn't go until we fill the new array, we should go until we'd finished the old one. Otherwise the element we are trying to kill will remain on the cyclic lists... That crap used to be masked by several leaks, so it was not quite trivial to hit. Eric had fixed some of those leaks a while ago and the shit had hit the fan...

This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

Alan Stern noticed that e100 caused slab corruption. commit 98468efddb101f8a29af974101c17ba513b07be1 changed the allocation of cbs to use dma pools that don't return zeroed memory, especially the cb->status field used to track which cb to clean, causing (the visible) double freeing of skbs and a wrong free cbs count. Now the cbs are explicitly zeroed at allocation time.

2009-12-18ocfs2: Set i_nlink properly during reflink.Tao Ma
We create a file in orphan dir for reflink so that if there is any error, we don't create any wrong dentry in the dir. But actually the file in orphan dir should be i_nlink = 0 so that it can be replayed and freed successfully. This patch first set i_nlink to 0 when creating the file in orphan dir and then set it to 1(reflink now only works for regular file) when we move it to the dest dir.

2009-12-18ocfs2: Add reflinked file's inode to inode hash eariler.Tao Ma
We used to add reflinked file's inode to inode hash when we add it to the dest dir. But actually there is a race. Consider the following sequence. 1. reflink happens and create the inode in orphan dir. 2. reflink thread is scheduled out because of some io. 3. recovery begins to work and calls ocfs2_recover_orphans. It calls ocfs2_iget and get a new inode and i_count = 1. It calls iput then and delete inode. the buffer's uptodate state is cleared. This patch move insert_inode_hash to the create function so that it can be found by step 3 and prevented from deleting because i_count > 1.

2009-12-18perf session: Make events_stats u64 to avoid overflow on 32-bit archesArnaldo Carvalho de Melo
Pekka Enberg reported weird percentages in perf report. It turns out we are overflowing a 32-bit variables in struct events_stats on 32-bit architectures.

2009-12-18ARM: Convert VFP/Crunch/XscaleCP thread_release() to exit_thread()Russell King
This avoids races in the VFP code where the dead thread may have state on another CPU. By moving this code to exit_thread(), we will be running as the thread, and therefore be running on the current CPU. This means that we can ensure that the only local state is accessed in the thread notifiers.

2009-12-18hw-breakpoints: Fix hardware breakpoints -> perf events dependencyFrederic Weisbecker
The kbuild's select command doesn't propagate through the config dependencies. Hence the current rules of hardware breakpoint's config can't ensure perf can never be disabled under us. We have: config X86 selects HAVE_HW_BREAKPOINTS config HAVE_HW_BREAKPOINTS select PERF_EVENTS config PERF_EVENTS [...] x86 will select the breakpoints but that won't propagate to perf events. The user can still disable the latter, but it is necessary for the breakpoints. What we need is: - x86 selects HAVE_HW_BREAKPOINTS and PERF_EVENTS - HAVE_HW_BREAKPOINTS depends on PERF_EVENTS so that we ensure PERF_EVENTS is enabled and frozen for x86. This fixes the following kind of build errors: In file included from arch/x86/kernel/hw_breakpoint.c:31: include/linux/hw_breakpoint.h: In function 'hw_breakpoint_addr': include/linux/hw_breakpoint.h:39: error: 'struct perf_event' has no member named 'attr' v2: Select also ANON_INODES from x86, required for perf Reported-by: Cyrill Gorcunov <gorcunov@gmail.com> Reported-by: Michal Marek <mmarek@suse.cz> Reported-by: Andrew Randrianasulu <randrik_a@yahoo.com> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Randy Dunlap <randy.dunlap@oracle.com> Cc: K.Prasad <prasad@linux.vnet.ibm.com> LKML-Reference: <1261010034-7786-1-git-send-regression-fweisbec@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-12-18sound: sgio2audio/pdaudiocf/usb-audio: initialize PCM bufferClemens Ladisch
When allocating the PCM buffer, use vmalloc_user() instead of vmalloc(). Otherwise, it would be possible for applications to play the previous contents of the kernel memory to the speakers, or to read it directly if the buffer is exported to userspace.
