* [PATCH] NFS: Cache invalidation fixupTrond Myklebust2006-10-211-0/+6
| | | | | | | | | | | | | | | | 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 Myklebust2006-10-212-38/+106
| | | | | | | | | | | | | | | | | | | | | 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. This behaviour is needed in order to avoid issues such as http://bugzilla.kernel.org/show_bug.cgi?id=7178 Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: Miklos Szeredi <miklos@szeredi.hu> Cc: Maneesh Soni <maneesh@in.ibm.com> Cc: Dipankar Sarma <dipankar@in.ibm.com> Cc: Neil Brown <neilb@cse.unsw.edu.au> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] Remove SUID when splicing into an inodeJens Axboe2006-10-191-4/+15
| | | | | | | | | | | | | | | | | | | | 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 Fasheh2006-10-191-14/+66
| | | | | | | | | | | | | | | | | | | | | | 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 Fasheh2006-10-192-13/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A disk generated some I/O error, after it, I hitted J_ASSERT(transaction->t_updates > 0) in journal_stop(). It seems to happened on ext3_truncate() path from stack trace. Then, maybe the following case may trigger J_ASSERT(transaction->t_updates > 0). ext3_truncate() -> ext3_free_branches() -> ext3_journal_test_restart() -> ext3_journal_restart() -> journal_restart() transaction->t_updates--; /* another process aborted journal */ -> start_this_handle() returns -EROFS without transaction->t_updates++; -> ext3_journal_stop() -> journal_stop() J_ASSERT(transaction->t_updates > 0) If journal was aborted in middle of journal_restart(), ext3_truncate() may trigger J_ASSERT().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a) ERR_PTR(nfserr_something) is a bad idea; IS_ERR() will be false for it. b) mixing nfserr_.... with -EOPNOTSUPP is even worse idea. nfsd4_path() does both; caller expects to get NFS protocol error out it if anything goes wrong, but if it does we either do not notice (see (a)) or get host-endian negative (see (b)). IOW, that's a case when we can't use ERR_PTR() to return error, even though we return a pointer in case of success.

* | [PATCH] NFS: Deal with failure of invalidate_inode_pages2()Trond Myklebust2006-10-203-18/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If invalidate_inode_pages2() fails, then it should in principle just be because the current process was signalled. In that case, we just want to ensure that the inode's page cache remains marked as invalid. Also add a helper to allow the O_DIRECT code to simply mark the page cache as invalid once it is finished writing, instead of calling invalidate_inode_pages2() itself.
