minixfs: misplaced checks lead to dentry leak

2012-01-04T23:03:06Z

bitmap size sanity checks should be done *before* allocating ->s_root; there their cleanup on failure would be correct. As it is, we do iput() on root inode, but leak the root dentry... Signed-off-by: Al Viro Acked-by: Josh Boyer Signed-off-by: Linus Torvalds

[CIFS] default ntlmv2 for cifs mount delayed to 3.3

2012-01-04T13:54:40Z

Turned out the ntlmv2 (default security authentication) upgrade was harder to test than expected, and we ran out of time to test against Apple and a few other servers that we wanted to. Delay upgrade of default security from ntlm to ntlmv2 (on mount) to 3.3. Still works fine to specify it explicitly via "sec=ntlmv2" so this should be fine.

cifs: fix bad buffer length check in coalesce_t2

2012-01-04T02:34:17Z

The current check looks to see if the RFC1002 length is larger than CIFSMaxBufSize, and fails if it is. The buffer is actually larger than that by MAX_CIFS_HDR_SIZE. This bug has been around for a long time, but the fact that we used to cap the clients MaxBufferSize at the same level as the server tended to paper over it. Commit c974befa changed that however and caused this bug to bite in more cases.

procfs: do not confuse jiffies with cputime64_t

2011-12-30T00:31:57Z

Commit 2a95ea6c0d129b4 ("procfs: do not overflow get_{idle,iowait}_time for nohz") did not take into account that one some architectures jiffies and cputime use different units. This causes get_idle_time() to return numbers in the wrong units, making the idle time fields in /proc/stat wrong. Instead of converting the usec value returned by get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function usecs_to_cputime64 to convert it to the correct unit of cputime64_t.

ceph: disable use of dcache for readdir etc.

2011-12-29T16:05:14Z

Ceph attempts to use the dcache to satisfy negative lookups and readdir when the entire directory contents are in cache. Disable this behavior until lingering bugs in this code are shaken out; we'll re-enable these hooks once things are fully stable. Signed-off-by: Sage Weil

vfs: fix handling of lock allocation failure in lease-break case

2011-12-26T18:25:26Z

Bruce Fields notes that commit 778fc546f749 ("locks: fix tracking of inprogress lease breaks") introduced a possible error pointer dereference on failure to allocate memory. locks_conflict() will dereference the passed-in new lease lock structure that may be an error pointer. This means an open (without O_NONBLOCK set) on a file with a lease applied (generally only done when Samba or nfsd (with v4) is running) could crash if a kmalloc() fails. So instead of playing games with IS_ERROR() all over the place, just check the allocation failure early. That makes the code more straightforward, and avoids this possible bad pointer dereference.
