2008-03-07NFS: Fix dentry revalidation for NFSv4 referrals and mountpoint crossingsTrond Myklebust
As long as the directory contents haven't changed, we should just let the path walk proceed to cross the mountpoint. Apart from being an optimisation in the case of 'nohide' mountpoint traversals, it also fixes an issue with referrals: referral inodes don't have valid filehandles, so calling nfs_revalidate_inode() on them is a bug.

2008-03-07NFS: Fix the fsid revalidation in nfs_update_inode()Trond Myklebust
When we detect that we've crossed a mountpoint on the remote server, we must take care not to use that inode to revalidate the fsid on our current superblock. To do so, we label the inode as a remote mountpoint, and check for that in nfs_update_inode(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

If the radix_tree_preload() fails, we need to destroy the inode we just read in before trying again. This could leak xfs_vnode structures when there is memory pressure. Noticed by Christoph Hellwig.

wakeups Idle state is not being detected properly by the xfsaild push code. The current idle state is detected by an empty list which may never happen with mostly idle filesystem or one using lazy superblock counters. A single dirty item in the list that exists beyond the push target can result repeated looping attempting to push up to the target because it fails to check if the push target has been acheived or not. Fix by considering a dirty list with everything past the target as an idle state and set the timeout appropriately.

2008-03-06NFS: use new LSM interfaces to explicitly set mount optionsEric Paris
NFS and SELinux worked together previously because SELinux had NFS specific knowledge built in. This design was approved by both groups back in 2004 but the recent NFS changes to use nfs_parsed_mount_data and the usage of nfs_clone_mount_data showed this to be a poor fragile solution. This patch fixes the NFS functionality regression by making use of the new LSM interfaces to allow an FS to explicitly set its own mount options. The explicit setting of mount options is done in the nfs get_sb functions which are called before the generic vfs hooks try to set mount options for filesystems which use text mount data. This does not currently support NFSv4 as that functionality did not exist in previous kernels and thus there is no regression. I will be adding the needed code, which I believe to be the exact same as the v3 code, in nfs4_get_sb for 2.6.26.

2008-03-06LSM/SELinux: Interfaces to allow FS to control mount optionsEric Paris
Introduce new LSM interfaces to allow an FS to deal with their own mount options. This includes a new string parsing function exported from the LSM that an FS can use to get a security data blob and a new security data blob. This is particularly useful for an FS which uses binary mount data, like NFS, which does not pass strings into the vfs to be handled by the loaded LSM. Also fix a BUG() in both SELinux and SMACK when dealing with binary mount data. If the binary mount data is less than one page the copy_page() in security_sb_copy_data() can cause an illegal page fault and boom. Remove all NFSisms from the SELinux code since they were broken by past NFS changes.

2008-03-04eCryptfs: make ecryptfs_prepare_write decrypt the pageMichael Halcrow
When the page is not up to date, ecryptfs_prepare_write() should be acting much like ecryptfs_readpage(). This includes the painfully obvious step of actually decrypting the page contents read from the lower encrypted file. Note that this patch resolves a bug in eCryptfs in 2.6.24 that one can produce with these steps: # mount -t ecryptfs /secret /secret # echo "abc" > /secret/file.txt # umount /secret # mount -t ecryptfs /secret /secret # echo "def" >> /secret/file.txt # cat /secret/file.txt Without this patch, the resulting data returned from cat is likely to be something other than "abc\ndef\n".

2008-03-03Allow ARG_MAX execve string space even with a small stack limitLinus Torvalds
The new code that removed the limitation on the execve string size (which was historically 32 pages) replaced it with a much softer limit based on RLIMIT_STACK which is usually much larger than the traditional limit. See commit b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") for details. However, if you have a small stack limit (perhaps because you need lots of stacks in a threaded environment), the new heuristic of allowing up to 1/4th of RLIMIT_STACK to be used for argument and environment strings could actually be smaller than the old limit. So just say that it's ok to have up to ARG_MAX strings regardless of the value of RLIMIT_STACK, and check the rlimit only when going over that traditional limit. (Of course, if you actually have a *really* small stack limit, the whole stack itself will be limited before you hit ARG_MAX, but that has always been true and is clearly the right behaviour anyway).

2008-02-28[XFS] If you mount an XFS filesystem with no mount options at all, thenJosef Jeff Sipek
the "ikeep" option is set rather than "noikeep". This regression was introduced in 970451. With no mount options specified, xfs_parseargs() does the following: int ikeep = 0; args->flags |= XFSMNT_BARRIER; args->flags2 |= XFSMNT2_COMPAT_IOSIZE; if (!options) goto done; It only sets the above two options by default and before, it also used to set XFSMNT_IDELETE by default. If options are specified, then if (!(args->flags & XFSMNT_DMAPI) && !ikeep) args->flags |= XFSMNT_IDELETE; is executed later on which is skipped by the "goto done;" above. The solution is to invert the logic.

2008-02-25ext4: set EXT4_EXTENTS_FL only for directory and regular filesAneesh Kumar K.V
In addition, don't inherit EXT4_EXTENTS_FL from parent directory. If we have a directory with extent flag set and later mount the file system with -o noextents, the files created in that directory will also have extent flag set but we would not have called ext4_ext_tree_init for them. This will cause error later when we are verifying the extent header Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Acked-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
