* ocfs2/dlm: Add missing dlm_lock_put()sSunil Mushran2008-03-102-0/+12
| | | | | | | | | | | | | | | | | | | 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.

* ocfs2: Fix endian bug in o2dlm protocol negotiation.Joel Becker2008-03-102-45/+76
| | | | | | | | | | | | | | | 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.

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.

* | | NFS: use new LSM interfaces to explicitly set mount optionsEric Paris2008-03-052-2/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | LSM/SELinux: Interfaces to allow FS to control mount optionsEric Paris2008-03-051-2/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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".

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).

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.

| | * | ext4: Fix BUG when writing to an unitialized extentMingming Cao2008-02-252-3/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug when writing to preallocated but uninitialized blocks, which resulted in a BUG in fs/buffer.c saying that the buffer is not mapped. When writing to a file, ext4_get_block_wrap() is called with create=1 in order to request that blocks be allocated if necessary. It currently calls ext4_get_blocks() with create=0 in order to do a lookup first. If the inode contains an unitialized data block, the buffer head is left unampped, which ext4_get_blocks_wrap() returns, causing the BUG. We fix this by checking to see if the buffer head is unmapped, and if so, we make sure the the buffer head is mapped by calling ext4_ext_get_blocks with create=1.

| | * | ext4: Don't use ext4_dec_count() if not neededTheodore Ts'o2008-02-151-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ext4_dec_count() function is only needed when dropping the i_nlink count on inodes which are (or which could be) directories. If we *know* that the inode in question can't possibly be a directory, use drop_nlink or clear_nlink() if we know i_nlink is 1. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
| | * | ext4: modify block allocation algorithm for the last groupValerie Clement2008-02-152-2/+14

Depending on the current process's pid, ext4_find_near() and ext4_ext_find_goal() can return a block number greater than the maximum blocks count in the filesystem and in that case the block will be not allocated in the same group as the inode. The following patch fixes the problem. Should the modification also be done in ext2/3 code?
