* [PATCH] Fix buffer overflow and races in capi debug functionsKarsten Keil2007-03-01
| | | | | | | | | | | | | The CAPI trace debug functions were using a fixed size buffer, which can be overflowed if wrong formatted CAPI messages were sent to the kernel capi layer. The code was also not protected against multiple callers. This fix bug 8028. Additionally the patch make the CAPI trace functions optional.

* [PATCH] adapt page_lock_anon_vma() to PREEMPT_RCUOleg Nesterov2007-03-01
| | | | | | | | | | | | | | | | | | | page_lock_anon_vma() uses spin_lock() to block RCU. This doesn't work with PREEMPT_RCU, we have to do rcu_read_lock() explicitely. Otherwise, it is theoretically possible that slab returns anon_vma's memory to the system before we do spin_unlock(&anon_vma->lock). [ Hugh points out that this only matters for PREEMPT_RCU, which isn't merged yet, and may never be. Regardless, this patch is conceptually the right thing to do, even if it doesn't matter at this point. - Linus ] Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Cc: Paul McKenney <paulmck@linux.vnet.ibm.com> Cc: Nick Piggin <nickpiggin@yahoo.com.au> Cc: Christoph Lameter <clameter@engr.sgi.com> Acked-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* [PATCH] sched: fix SMT scheduler bugIngo Molnar2007-03-01
| | | | | | | | | | | | | | | | | | | | The SMT scheduler incorrectly skips kernel threads even if they are runnable (but they are preempted by a higher-prio user-space task which got SMT-delayed by an even higher-priority task running on a sibling CPU). Fix this for now by only doing the SMT-nice optimization if the to-be-delayed task is the only runnable task. (This should cover most of the real-life cases anyway.) This bug has been in the SMT scheduler since 2.6.17 or so, but has only been noticed now by the active check in the dynticks code.

* [PATCH] ext[34]: EA block reference count racing fixMingming Cao2007-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are race issues around ext[34] xattr block release code. ext[34]_xattr_release_block() checks the reference count of xattr block (h_refcount) and frees that xattr block if it is the last one reference it. Unlike ext2, the check of this counter is unprotected by any lock. ext[34]_xattr_release_block() will free the mb_cache entry before freeing that xattr block. There is a small window between the check for the re h_refcount ==1 and the call to mb_cache_entry_free(). During this small window another inode might find this xattr block from the mbcache and reuse it, racing a refcount updates. The xattr block will later be freed by the first inode without notice other inode is still use it. Later if that block is reallocated as a datablock for other file, then more serious problem might happen. We need put a lock around places checking the refount as well to avoid racing issue. Another place need this kind of protection is in ext3_xattr_block_set(), where it will modify the xattr block content in- the-fly if the refcount is 1 (means it's the only inode reference it). This will also fix another issue: the xattr block may not get freed at all if no lock is to protect the refcount check at the release time. It is possible that the last two inodes could release the shared xattr block at the same time. But both of them think they are not the last one so only decreased the h_refcount without freeing xattr block at all. We need to call lock_buffer() after ext3_journal_get_write_access() to avoid deadlock (because the later will call lock_buffer()/unlock_buffer () as well).

* [PATCH] uml: host VDSO fixJeff Dike2007-03-01
| | | | | | | | | | | | | | | | | | | | This fixes a problem seen by a number of people running UML on newer host kernels. init would hang with an infinite segfault loop. It turns out that the host kernel was providing a AT_SYSINFO_EHDR of 0xffffe000, which faked UML into believing that the host VDSO page could be reused. However, AT_SYSINFO pointed into the middle of the address space, and was unmapped as a result. Because UML was providing AT_SYSINFO_EHDR and AT_SYSINFO to its own processes, these would branch to nowhere when trying to use the VDSO. The fix is to also check the location of AT_SYSINFO when deciding whether to use the host's VDSO.

* [PATCH] md: fix raid10 recovery problem.NeilBrown2007-03-01
| | | | | | | | | | | | | | | | | | | | There are two errors that can lead to recovery problems with raid10 when used in 'far' more (not the default). Due to a '>' instead of '>=' the wrong block is located which would result in garbage being written to some random location, quite possible outside the range of the device, causing the newly reconstructed device to fail. The device size calculation had some rounding errors (it didn't round when it should) and so recovery would go a few blocks too far which would again cause a write to a random block address and probably a device error. The code for working with device sizes was fairly confused and spread out, so this has been tided up a bit.

* [PATCH] x86_64/i386 irq: Fix !CONFIG_SMP compilationEric W. Biederman2007-02-28
| | | | | | | | | | | | | | | | | | | | | | When removing set_native_irq I missed the fact that it was called in a couple of places that were compiled even when SMP support is disabled. And since the irq_desc[].affinity field only exists in SMP things broke. Thanks to Simon Arlott <simon@arlott.org> for spotting this. There are a couple of ways to fix this but the simplest one is to just remove the assignments. The affinity field is only used to display a value to the user, and nothing on either i386 or x86_64 reads it or depends on it being any particlua value, so skipping the assignment is safe. The assignment that is being removed is just for the initial affinity value before the user explicitly sets it. The irq_desc array initializes this field to CPU_MASK_ALL so the field is initialized to a reasonable value in the SMP case without being set. Signed-off-by: Eric W.

| | | | | | | | | | | When the PCI controller OBP node lacks an interrupt-map and interrupt-map-mask property, we need to form the INO by hand. The PCI swizzle logic was not doing that properly. This was a regression added by the of_device code. Signed-off-by: David S. Miller <davem@davemloft.net>
