2009-08-27AFS: Stop readlink() on AFS crashing due to NULL 'file' ptrDavid Howells1-3/+15
kAFS crashes when asked to read a symbolic link because page_getlink() passes a NULL file pointer to read_mapping_page(), but afs_readpage() expects a file pointer from which to extract a key. Modify afs_readpage() to request the appropriate key from the calling process's keyrings if a file struct is not supplied with one attached.

2009-06-16AFS: Correctly translate auth error aborts and don't failover in such casesDavid Howells2-0/+18
Authentication error abort codes should be translated to appropriate Linux error codes, rather than all being translated to EREMOTEIO - which indicates that the server had internal problems. Additionally, a server shouldn't be marked unavailable and the next server tried if an authentication error occurs. This will quickly make all the servers unavailable to the client. Instead the error should be returned straight to the user. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-06-11push BKL down into ->put_superChristoph Hellwig1-0/+4
Move BKL into ->put_super from the only caller. A couple of filesystems had trivial enough ->put_super (only kfree and NULLing of s_fs_info + stuff in there) to not get any locking: coda, cramfs, efs, hugetlbfs, omfs, qnx4, shmem, all others got the full treatment. Most of them probably don't need it, but I'd rather sort that out individually. Preferably after all the other BKL pushdowns in that area. [AV: original used to move lock_super() down as well; these changes are removed since we don't do lock_super() at all in generic_shutdown_super() now] [AV: fuse, btrfs and xfs are known to need no damn BKL, exempt] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan1-1/+0
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

2009-01-04fs: symlink write_begin allocation context fixNick Piggin1-1/+1
With the write_begin/write_end aops, page_symlink was broken because it could no longer pass a GFP_NOFS type mask into the point where the allocations happened. They are done in write_begin, which would always assume that the filesystem can be entered from reclaim. This bug could cause filesystem deadlocks. The funny thing with having a gfp_t mask there is that it doesn't really allow the caller to arbitrarily tinker with the context in which it can be called. It couldn't ever be GFP_ATOMIC, for example, because it needs to take the page lock. The only thing any callers care about is __GFP_FS anyway, so turn that into a single flag. Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on this flag in their write_begin function. Change __grab_cache_page to accept a nofs argument as well, to honour that flag (while we're there, change the name to grab_cache_page_write_begin which is more instructive and does away with random leading underscores). This is really a more flexible way to go in the end anyway -- if a filesystem happens to want any extra allocations aside from the pagecache ones in ints write_begin function, it may now use GFP_KERNEL (rather than GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a random example).

This is a much better version of a previous patch to make the parser tables constant.

The i_version field of the inode is changed to be a 64-bit counter that is set on every inode creation and that is incremented every time the inode data is modified (similarly to the "ctime" time-stamp). The aim is to fulfill a NFSv4 requirement for rfc3530. This first part concerns the vfs, it converts the 32-bit i_version in the generic inode to a 64-bit, a flag is added in the super block in order to check if the feature is enabled and the i_version is incremented in the vfs.
