During migration, the recovery master node may be asked to master a lockres it may not know about. In that case, it would not only have to create a lockres and add it to the hash, but also remember to to do the _put_ corresponding to the kref_init in dlm_init_lockres(), as soon as the migration is completed. Yes, we don't wait for the dlm_purge_lockres() to do that matching put. Note the ref added for it being in the hash protects the lockres from being freed prematurely. This patch adds that missing put, as described above, to plug a memleak.

Normally locks for remote nodes are freed when that node sends an UNLOCK message to the master. The master node tags an DLM_UNLOCK_FREE_LOCK action to do an extra put on the lock at the end. However, there are times when the master node has to free the locks for the remote nodes forcibly. Two cases when this happens are: 1. When the master has migrated the lockres plus all locks to another node. 2. When the master is clearing all the locks of a dead node. It was in the above two conditions that the dlm was missing the extra put.

struct dlm_query_join_packet is made up of four one-byte fields. They are effectively in big-endian order already. However, little-endian machines swap them before putting the packet on the wire (because query_join's response is a status, and that status is treated as a u32 on the wire). Thus, a big-endian and little-endian machines will treat this structure differently. The solution is to have little-endian machines swap the structure when converting from the structure to the u32 representation.

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.

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: NTrond Myklebust <Trond.Myklebust@netapp.com>

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.

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.

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.

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".

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 b6a2fea3 ("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).

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.
