2009-03-30reiserfs: cleanup path functionsJeff Mahoney
This patch cleans up some redundancies in the reiserfs tree path code. decrement_bcount() is essentially the same function as brelse(), so we use that instead. decrement_counters_in_path() is exactly the same function as pathrelse(), so we kill that and use pathrelse() instead. There's also a bit of cleanup that makes the code a bit more readable. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: factor out buffer_info initializationJeff Mahoney

2009-03-30reiserfs: add atomic addition of selinux attributes during inode creationJeff Mahoney
Some time ago, some changes were made to make security inode attributes be atomically written during inode creation. ReiserFS fell behind in this area, but with the reworking of the xattr code, it's now fairly easy to add. The following patch adds the ability for security attributes to be added automatically during inode creation. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: use generic readdir for operations across all xattrsJeff Mahoney
The current reiserfs xattr implementation open codes reiserfs_readdir and frees the path before calling the filldir function. Typically, the filldir function is something that modifies the file system, such as a chown or an inode deletion that also require reading of an inode associated with each direntry. Since the file system is modified, the path retained becomes invalid for the next run. In addition, it runs backwards in attempt to minimize activity. This is clearly suboptimal from a code cleanliness perspective as well as performance-wise. This patch implements a generic reiserfs_for_each_xattr that uses the generic readdir and a specific filldir routine that simply populates an array of dentries and then performs a specific operation on them. When all files have been operated on, it then calls the operation on the directory itself. The result is a noticable code reduction and better performance.

2009-03-30reiserfs: journaled xattrsJeff Mahoney
Deadlocks are possible in the xattr code between the journal lock and the xattr sems. This patch implements journalling for xattr operations. The benefit is twofold: * It gets rid of the deadlock possibility by always ensuring that xattr write operations are initiated inside a transaction. * It corrects the problem where xattr backing files aren't considered any differently than normal files, despite the fact they are metadata. I discussed the added journal load with Chris Mason, and we decided that since xattrs (versus other journal activity) is fairly rare, the introduction of larger transactions to support journaled xattrs wouldn't be too big a deal.

2009-03-30reiserfs: use generic xattr handlersJeff Mahoney
Christoph Hellwig had asked me quite some time ago to port the reiserfs xattrs to the generic xattr interface. This patch replaces the reiserfs-specific xattr handling code with the generic struct xattr_handler. However, since reiserfs doesn't split the prefix and name when accessing xattrs, it can't leverage generic_{set,get,list,remove}xattr without needlessly reconstructing the name on the back end. Update 7/26/07: Added missing dput() to deletion path. Update 8/30/07: Added missing mark_inode_dirty when i_mode is used to represent an ACL and no previous ACL existed.

2009-03-30reiserfs: remove i_has_xattr_dirJeff Mahoney
With the changes to xattr root locking, the i_has_xattr_dir flag is no longer needed. This patch removes it. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: make per-inode xattr locking more fine grainedJeff Mahoney
The per-inode locking can be made more fine-grained to surround just the interaction with the filesystem itself. This really only applies to protecting reads during a write, since concurrent writes are barred with inode->i_mutex at the vfs level. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: eliminate per-super xattr lockJeff Mahoney
With the switch to using inode->i_mutex locking during lookups/creation in the xattr root, the per-super xattr lock is no longer needed. This patch removes it. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: simplify xattr internal file lookups/opensJeff Mahoney
The xattr file open/lookup code is needlessly complex. We can use vfs-level operations to perform the same work, and also simplify the locking constraints. The locking advantages will be exploited in future patches. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unsetJeff Mahoney
The current reiserfs xattr implementation will not clean up old xattr files if files are deleted when REISERFS_FS_XATTR is unset. This results in inaccessible lost files, wasting space. This patch compiles in basic xattr knowledge, such as how to delete them and change ownership for quota tracking. If the file system has never used xattrs, then the operation is quite fast: it returns immediately when it sees there is no .reiserfs_priv directory. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: remove IS_PRIVATE helpersJeff Mahoney
There are a number of helper functions for marking a reiserfs inode private that were leftover from reiserfs did its own thing wrt to private inodes. S_PRIVATE has been in the kernel for some time, so this patch removes the helpers and uses IS_PRIVATE instead. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: remove link detection codeJeff Mahoney
Early in the reiserfs xattr development, there was a plan to use hardlinks to save disk space for identical xattrs. That code never materialized and isn't going to, so this patch removes the detection code. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-03-30reiserfs: introduce reiserfs_error()Jeff Mahoney
Although reiserfs can currently handle severe errors such as journal failure, it cannot handle less severe errors like metadata i/o failure. The following patch adds a reiserfs_error() function akin to the one in ext3. Subsequent patches will use this new error handler to handle errors more gracefully in general.

2009-03-30reiserfs: rearrange journal abortJeff Mahoney
This patch kills off reiserfs_journal_abort as it is never called, and combines __reiserfs_journal_abort_{soft,hard} into one function called reiserfs_abort_journal, which performs the same work. It is silent as opposed to the old version, since the message was always issued after a regular 'abort' message.

2009-03-30reiserfs: rework reiserfs_panicJeff Mahoney
ReiserFS panics can be somewhat inconsistent. In some cases: * a unique identifier may be associated with it * the function name may be included * the device may be printed separately This patch aims to make warnings more consistent. reiserfs_warning() prints the device name, so printing it a second time is not required. The function name for a warning is always helpful in debugging, so it is now automatically inserted into the output. Hans has stated that every warning should have a unique identifier. Some cases lack them, others really shouldn't have them. reiserfs_warning() now expects an id associated with each message. In the rare case where one isn't needed, "" will suffice.

2009-03-30reiserfs: add locking around error bufferJeff Mahoney
The formatting of the error buffer is race prone. It uses static buffers for both formatting and output. While overwriting the error buffer can product garbled output, overwriting the format buffer with incompatible % directives can cause crashes.

2009-03-30reiserfs: prepare_error_buf wrongly consumes va_argJeff Mahoney

2009-03-30reiserfs: audit transaction ids to always be unsigned intsJeff Mahoney
This patch fixes up the reiserfs code such that transaction ids are always unsigned ints. In places they can currently be signed ints or unsigned longs. The former just causes an annoying clm-2200 warning and may join a transaction when it should wait. The latter is just for correctness since the disk format uses a 32-bit transaction id. There aren't any runtime problems that result from it not wrapping at the correct location since the value is truncated correctly even on big endian systems. The 0 value might make it to disk, but the mount-time checks will bump it to 10 itself. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-03-28fix setuid sometimes wouldn'tHugh Dickins
check_unsafe_exec() also notes whether the fs_struct is being shared by more threads than will get killed by the exec, and if so sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid. But /proc/<pid>/cwd and /proc/<pid>/root lookups make transient use of get_fs_struct(), which also raises that sharing count. This might occasionally cause a setuid program not to change euid, in the same way as happened with files->count (check_unsafe_exec also looks at sighand->count, but /proc doesn't raise that one). We'd prefer exec not to unshare fs_struct: so fix this in procfs, replacing get_fs_struct() by get_fs_path(), which does path_get while still holding task_lock, instead of raising fs->count.

2009-03-28fix setuid sometimes doesn'tHugh Dickins
Joe Malicki reports that setuid sometimes doesn't: very rarely, a setuid root program does not get root euid; and, by the way, they have a health check running lsof every few minutes. Right, check_unsafe_exec() notes whether the files_struct is being shared by more threads than will get killed by the exec, and if so sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid. But /proc/<pid>/fd and /proc/<pid>/fdinfo lookups make transient use of get_files_struct(), which also raises that sharing count. There's a rather simple fix for this: exec's check on files->count has been redundant ever since 2.6.1 made it unshare_files() (except while compat_do_execve() omitted to do so) - just remove that check. [Note to -stable: this patch will not apply before 2.6.29: earlier releases should just remove the files->count line from unsafe_exec().] Reported-by: Joe Malicki <jmalicki@metacarta.com> Narrowed-down-by: Michael Itz <mitz@metacarta.com> Tested-by: Joe Malicki <jmalicki@metacarta.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-28compat_do_execve should unshare_filesHugh Dickins
2.6.26's commit fd8328be874f4190a811c58cd4778ec2c74d2c05 "sanitize handling of shared descriptor tables in failing execve()" moved the unshare_files() from flush_old_exec() and several binfmts to the head of do_execve(); but forgot to make the same change to compat_do_execve(), leaving a CLONE_FILES files_struct shared across exec from a 32-bit process on a 64-bit kernel. It's arguable whether the files_struct really ought to be unshared across exec; but 2.6.1 made that so to stop the loading binary's fd leaking into other threads, and a 32-bit process on a 64-bit kernel ought to behave in the same way as 32 on 32 and 64 on 64.

2009-03-27fs: avoid I_NEW inodesNick Piggin
To be on the safe side, it should be less fragile to exclude I_NEW inodes from inode list scans by default (unless there is an important reason to have them). Normally they will get excluded (eg. by zero refcount or writecount etc), however it is a bit fragile for list walkers to know exactly what parts of the inode state is set up and valid to test when in I_NEW. So along these lines, move I_NEW checks upward as well (sometimes taking I_FREEING etc checks with them too -- this shouldn't be a problem should it?)
