* eCryptfs: Remove ecryptfs_header_cache_2Tyler Hicks2011-05-29
| | | | | | | | | Now that ecryptfs_lookup_interpose() is no longer using ecryptfs_header_cache_2 to read in metadata, the kmem_cache can be removed and the ecryptfs_header_cache_1 kmem_cache can be renamed to ecryptfs_header_cache. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
* eCryptfs: Cleanup and optimize ecryptfs_lookup_interpose()Tyler Hicks2011-05-29
| | | | | | | | | | | | | | | ecryptfs_lookup_interpose() has turned into spaghetti code over the years. This is an effort to clean it up. - Shorten overly descriptive variable names such as ecryptfs_dentry - Simplify gotos and error paths - Create helper function for reading plaintext i_size from metadata It also includes an optimization when reading i_size from the metadata. A complete page-sized kmem_cache_alloc() was being done to read in 16 bytes of metadata. The buffer for that is now statically declared. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
* eCryptfs: Return useful code from contains_ecryptfs_markerTyler Hicks2011-05-29
| | | | | | | | | | | Instead of having the calling functions translate the true/false return code to either 0 or -EINVAL, have contains_ecryptfs_marker() return 0 or -EINVAL so that the calling functions can just reuse the return code. Also, rename the function to ecryptfs_validate_marker() to avoid callers mistakenly thinking that it returns true/false codes. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
* eCryptfs: Fix new inode race conditionTyler Hicks2011-05-29
| | | | | | | | | | | | Only unlock and d_add() new inodes after the plaintext inode size has been read from the lower filesystem. This fixes a race condition that was sometimes seen during a multi-job kernel build in an eCryptfs mount. https://bugzilla.kernel.org/show_bug.cgi?id=36002 Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com> Reported-by: David <david@unsolicited.net> Tested-by: David <david@unsolicited.net>
* eCryptfs: Cleanup inode initialization codeTyler Hicks2011-05-29
| | | | | | | | | | | | | | | | The eCryptfs inode get, initialization, and dentry interposition code has two separate paths. One is for when dentry interposition is needed after doing things like a mkdir in the lower filesystem and the other is needed after a lookup. Unlocking new inodes and doing a d_add() needs to happen at different times, depending on which type of dentry interposing is being done. This patch cleans up the inode get and initialization code paths and splits them up so that the locking and d_add() differences mentioned above can be handled appropriately in a later patch.

* eCryptfs: Consolidate inode functions into inode.cTyler Hicks2011-05-29
| | | | | | | | | | | These functions should live in inode.c since their focus is on inodes and they're primarily used by functions in inode.c. Also does a simple cleanup of ecryptfs_inode_test() and rolls ecryptfs_init_inode() into ecryptfs_inode_set().

| | | | | | | | | | | | | | | | The documentation is a little iffy as to whether these are actual MMRs, but reading them on the hardware works, and the previous version of this logic (the SDH) had PID[4567]. So add it for RSI too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code was mostly developed against a BF54x, so some BF537-specific issues were missed. The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse of the EPPI block). The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the sim does not catch misreads here so that'll need to get fixed. The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct to figure that out rather than hardcoding it locally. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* | mm: fix page_lock_anon_vma leaving mutex lockedHugh Dickins2011-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On one machine I've been getting hangs, a page fault's anon_vma_prepare() waiting in anon_vma_lock(), other processes waiting for that page's lock. This is a replay of last year's f18194275c39 "mm: fix hang on anon_vma->root->lock". The new page_lock_anon_vma() places too much faith in its refcount: when it has acquired the mutex_trylock(), it's possible that a racing task in anon_vma_alloc() has just reallocated the struct anon_vma, set refcount to 1, and is about to reset its anon_vma->root. Fix this by saving anon_vma->root, and relying on the usual page_mapped() check instead of a refcount check: if page is still mapped, the anon_vma is still ours; if page is not still mapped, we're no longer interested.

* | mm: fix kernel BUG at mm/rmap.c:1017!Hugh Dickins2011-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've hit the "address >= vma->vm_end" check in do_page_add_anon_rmap() just once. The stack showed khugepaged allocation trying to compact pages: the call to page_add_anon_rmap() coming from remove_migration_pte(). That path holds anon_vma lock, but does not hold mmap_sem: it can therefore race with a split_vma(), and in commit 5f70b962ccc2 "mmap: avoid unnecessary anon_vma lock" we just took away the anon_vma lock protection when adjusting vma->vm_end. I don't think that particular BUG_ON ever caught anything interesting, so better replace it by a comment, than reinstate the anon_vma locking.

* | tmpfs: fix race between truncate and writepageHugh Dickins2011-05-28
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | While running fsx on tmpfs with a memhog then swapoff, swapoff was hanging (interruptibly), repeatedly failing to locate the owner of a 0xff entry in the swap_map. Although shmem_writepage() does abandon when it sees incoming page index is beyond eof, there was still a window in which shmem_truncate_range() could come in between writepage's dropping lock and updating swap_map, find the half-completed swap_map entry, and in trying to free it, leave it in a state that swap_shmem_alloc() could not correct. Arguably a bug in __swap_duplicate()'s and swap_entry_free()'s handling of the different cases, but easiest to fix by moving swap_shmem_alloc() under cover of the lock. More interesting than the bug: it's been there since 2.6.33, why could I not see it with earlier kernels? The mmotm of two weeks ago seems to have some magic for generating races, this is just one of three I found. With yesterday's git I first saw this in mainline, bisected in search of that magic, but the easy reproducibility evaporated. Oh well, fix the bug.

| * Cache xattr security drop check for write v2Andi Kleen2011-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some recent benchmarking on btrfs showed that a major scaling bottleneck on large systems on btrfs is currently the xattr lookup on every write. Why xattr lookup on every write I hear you ask? write wants to drop suid and security related xattrs that could set o capabilities for executables. To do that it currently looks up security.capability on EVERY write (even for non executables) to decide whether to drop it or not. In btrfs this causes an additional tree walk, hitting some per file system locks and quite bad scalability. In a simple read workload on a 8S system I saw over 90% CPU time in spinlocks related to that. Chris Mason tells me this is also a problem in ext4, where it hits the global mbcache lock. This patch adds a simple per inode to avoid this problem. We only do the lookup once per file and then if there is no xattr cache the decision. All xattr changes clear the flag. I also used the same flag to avoid the suid check, although that one is pretty cheap. A file system can also set this flag when it creates the inode, if it has a cheap way to do so. This is done for some common file systems in followon patches. With this patch a major part of the lock contention disappears for btrfs. Some testing on smaller systems didn't show significant performance changes, but at least it helps the larger systems and is generally more efficient. v2: Rename is_sgid. add file system helper.
