[PATCH] fix de_thread() vs send_group_sigqueue() race

2005-11-11T05:18:55Z

When non-leader thread does exec, de_thread calls release_task(leader) before calling exit_itimers(). If local timer interrupt happens in between, it can oops in send_group_sigqueue() while taking ->sighand->siglock == NULL. However, we can't change send_group_sigqueue() to check p->signal != NULL, because sys_timer_create() does get_task_struct() only in SIGEV_THREAD_ID case. So it is possible that this task_struct was already freed and we can't trust p->signal. This patch changes de_thread() so that leader released after exit_itimers() call.

[PATCH] fix XFS_QUOTA for modular XFS

2005-11-11T05:18:54Z

This patch by Dimitri Puzin submitted through kernel Bugzilla #5514 fixes the following issue: Cannot build XFS filesystem support as module with quota support. It works only when the XFS filesystem support is compiled into the kernel. Menuconfig prevents from setting CONFIG_XFS_FS=m and CONFIG_XFS_QUOTA=y. How to reproduce: configure the XFS filesystem with quota support as module. The resulting kernel won't have quota support compiled into xfs.ko. Fix: Changing the fs/xfs/Kconfig file from tristate to bool lets you configure the quota support to be compiled into the XFS module. The Makefile-linux-2.6 checks only for CONFIG_XFS_QUOTA=y.

[PATCH] Fix HFS+ to free up the space when a file is deleted.

2005-10-26T17:39:43Z

fsck_hfs reveals lots of temporary files accumulating in the hidden directory "\000\000\000HFS+ Private Data". According to the HFS+ documentation these are files which are unlinked while in use. However, there may be a bug in the Linux hfsplus implementation which causes this to happen even when the files are not in use. It looks like the "opencnt" field is never initialized as (I think) it should be in hfsplus_read_inode. This means that a file can appear to be still in use when in fact it has been closed. This patch seems to fix it for me. Signed-off-by: Anton Altaparmakov Cc: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] inotify/idr leak fix

2005-10-23T23:38:39Z

Fix a bug which was reported and diagnosed by Stefan Jones IDR trees include a cache of idr_layer objects. There's no way to destroy this cache, so when we discard an overall idr tree we end up leaking some memory. Add and use idr_destroy() for this. v9fs and infiniband also need to use idr_destroy() to avoid leaks. Or, we make the cache global, like radix_tree_preload(). Which is probably better. Later.

[PATCH] aio syscalls are not checked by lsm

2005-10-23T23:38:38Z

Another case of missing call to security_file_permission: aio functions (namely, io_submit) does not check credentials with security modules. Below is the simple patch to the problem. It seems that it is enough to check for rights at the request submission time. Signed-off-by: Kostik Belousov Signed-off-by: Chris Wright Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] aio: revert lock_kiocb()

2005-10-18T00:03:57Z

lock_kiocb() was introduced to serialize retrying and cancellation. In the process of doing so it tried to sleep waiting for KIF_LOCKED while holding the ctx_lock spinlock. Recent fixes have ensured that multiple concurrent retries won't be attempted for a given iocb. Cancel has other problems and has no significant in-tree users that have been complaining about it. So for the immediate future we'll revert sleeping with the lock held and will address proper cancellation and retry serialization in the future.

[PATCH] output of /proc/maps on nommu systems is incomplete

2005-10-18T00:03:57Z

Currently you do not get all the map entries on nommu systems because the start function doesn't index into the list using the value of "pos". Signed-off-by: David McCullough Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] NFS: Fix Oopsable/unnecessary i_count manipulations in nfs_wait_on_inode()

2005-10-17T21:47:16Z

Oopsable since nfs_wait_on_inode() can get called as part of iput_final(). Unnecessary since the caller had better be damned sure that the inode won't disappear from underneath it anyway. Signed-off-by: Trond Myklebust Signed-off-by: Linus Torvalds

[PATCH] NFS: Fix cache consistency races

2005-10-17T21:47:16Z

If the data cache has been marked as potentially invalid by nfs_refresh_inode, we should invalidate it rather than assume that changes are due to our own activity. Also ensure that we always start with a valid cache before declaring it to be protected by a delegation. Signed-off-by: Trond Myklebust Signed-off-by: Linus Torvalds
