* [PATCH] splice: fix problem introduced with inode dietJens Axboe2006-11-04
| | | | | | | | | | | | After the inode slimming patch that unionised i_pipe/i_bdev/i_cdev, it's no longer enough to check for existance of ->i_pipe to verify that this is a pipe.

| * JFS: Remove redundant xattr permission checkingDave Kleikamp2006-11-02
| | | | | | | | | | | | | | | | The vfs handles most permissions for setting and retrieving xattrs. This patch removes a redundant and wrong check so that it won't override the correct behavior which is being fixed in the vfs. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
* | [PATCH] Fix user.* xattr permission check for sticky dirsAndreas Gruenbacher2006-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The user.* extended attributes are only allowed on regular files and directories. Sticky directories further restrict write access to the owner and privileged users. (See the attr(5) man page for an explanation.) The original check in ext2/ext3 when user.* xattrs were merged was more restrictive than intended, and when the xattr permission checks were moved into the VFS, read access to user.* attributes on sticky directores ended up being denied in addition.

* | [PATCH] reiserfs: reset errval after initializing bitmap cacheJeff Mahoney2006-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL until much later. If a condition fails before errval is reset later, reiserfs_fill_super() will mistakenly return 0, causing an Oops in do_add_mount(). This patch resets errval to -EINVAL after the call. I view this as a temporary fix and real error codes should be used throughout reiserfs_fill_super().

* | [PATCH] sys_pselect7 vs compat_sys_pselect7 uaccess error handlingHeiko Carstens2006-11-03

I ran into this too because of an old source tree, but my fix would look quite a bit different to Andi's fix. The reason is that the compat function IMHO should behave the very same as the non-compat function if possible. Since sys_pselect7 does not return -EFAULT in this specific case, change the compat code so it behaves like sys_pselect7.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add_bd_holder() is called from bd_claim_by_kobject to put a given struct bd_holder in the list if there is no matching entry. There are 3 possible results of add_bd_holder(): 1. there is no matching entry and add the given one to the list 2. there is matching entry, so just increment reference count of the existing one 3. something failed during its course 1 and 2 are successful cases. But for case 2, someone has to free the unused struct bd_holder. The current code frees it inside of add_bd_holder and returns same value 0 for both cases 1 and 2. However, it's natural and less error-prone if caller frees it since it's allocated by the caller.

However as far as I see this comment is not correct: when we cannot take s_umount rw_semaphore (for example because it was taken in do_remount) this dentry is already extracted from dentry_unused list and we do not add it into the list again. Therefore dentry will not be found by prune_dcache() and shrink_dcache_sb() and will leave in memory very long time until the partition will be unmounted. The patch adds this dentry into tail of the dentry_unused list.

* [PATCH] hugetlb: fix prio_tree unitHugh Dickins2006-10-28
| | | | | | | | | | | | | | | | | | | | | hugetlb_vmtruncate_list was misconverted to prio_tree: its prio_tree is in units of PAGE_SIZE (PAGE_CACHE_SIZE) like any other, not HPAGE_SIZE (whereas its radix_tree is kept in units of HPAGE_SIZE, otherwise slots would be absurdly sparse). At first I thought the error benign, just calling __unmap_hugepage_range on more vmas than necessary; but on 32-bit machines, when the prio_tree is searched correctly, it happens to ensure the v_offset calculation won't overflow. As it stood, when truncating at or beyond 4GB, it was liable to discard pages COWed from lower offsets; or even to clear pmd entries of preceding vmas, triggering exit_mmap's BUG_ON(nr_ptes).

* [PATCH] jbd2: journal_dirty_data re-check for unmapped buffersEric Sandeen2006-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | When running several fsx's and other filesystem stress tests, we found cases where an unmapped buffer was still being sent to submit_bh by the ext3 dirty data journaling code. I saw this happen in two ways, both related to another thread doing a truncate which would unmap the buffer in question. Either we would get into journal_dirty_data with a bh which was already unmapped (although journal_dirty_data_fn had checked for this earlier, the state was not locked at that point), or it would get unmapped in the middle of journal_dirty_data when we dropped locks to call sync_dirty_buffer. By re-checking for mapped state after we've acquired the bh state lock, we should avoid these races. If we find a buffer which is no longer mapped, we essentially ignore it, because journal_unmap_buffer has already decided that this buffer can go away. I've also added tracepoints in these two cases, and made a couple other tracepoint changes that I found useful in debugging this.

* | [PATCH] NFS: Cache invalidation fixupTrond Myklebust2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If someone has renamed a directory on the server, triggering the d_move code in d_materialise_unique(), then we need to invalidate the cached directory information in the source parent directory.

* | [PATCH] VFS: Make d_materialise_unique() enforce directory uniquenessTrond Myklebust2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the caller tries to instantiate a directory using an inode that already has a dentry alias, then we attempt to rename the existing dentry instead of instantiating a new one. Fail with an ELOOP error if the rename would affect one of our parent directories.

| * | [PATCH] Remove SUID when splicing into an inodeJens Axboe2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally from Mark Fasheh <mark.fasheh@oracle.com> generic_file_splice_write() does not remove S_ISUID or S_ISGID. This is inconsistent with the way we generally write to files. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
| * | [PATCH] Introduce generic_file_splice_write_nolock()Mark Fasheh2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows file systems to manage their own i_mutex locking while still re-using the generic_file_splice_write() logic. OCFS2 in particular wants this so that it can order cluster locks within i_mutex. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
| * | [PATCH] Take i_mutex in splice_from_pipe()Mark Fasheh2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The splice_actor may be calling ->prepare_write() and ->commit_write(). We want i_mutex on the inode being written to before calling those so that we don't race i_size changes. The double locking behavior is done elsewhere in splice.c, and if we eventually want _nolock variants of generic_file_splice_write(), fs modules might have to replicate the nasty locking code. We introduce inode_double_lock() and inode_double_unlock() to consolidate the locking rules into one set of functions.
