      fix memory leak in CIFSFindNext · 6353450a
      由 Jeff Layton 提交于 
      When CIFSFindNext gets back an -EBADF from a call, it sets the return
code of the function to 0 and eventually exits. Doing this makes the
cleanup at the end of the function skip freeing the SMB buffer, so
we need to make sure we free the buffer explicitly when doing this.

If we don't you end up with errors like this when unplugging the cifs
kernel module:

slab error in kmem_cache_destroy(): cache `cifs_request': Can't free all objects
 [<c046bdbf>] kmem_cache_destroy+0x61/0xf3

      [CIFS] when not using unix extensions, check for and set ATTR_READONLY on create and mkdir · 67750fb9
      由 Jeff Layton 提交于 
      When creating a directory on a CIFS share without POSIX extensions,
and the given mode has no write bits set, set the ATTR_READONLY bit.

When creating a file, set ATTR_READONLY if the create mode has no write
bits set and we're not using unix extensions.

There are some comments about this being problematic due to the VFS
splitting creates into 2 parts. I'm not sure what that's actually
talking about, but I'm assuming that it has something to do with how
mknod is implemented. In the simple case where we have no unix
extensions and we're just creating a regular file, there's no reason
we can't set ATTR_READONLY.

      [CIFS] Fix buffer overflow if server sends corrupt response to small · 133672ef
      由 Steve French 提交于 
      request

In SendReceive() function in transport.c - it memcpy's
message payload into a buffer passed via out_buf param. The function
assumes that all buffers are of size (CIFSMaxBufSize +
MAX_CIFS_HDR_SIZE) , unfortunately it is also called with smaller
(MAX_CIFS_SMALL_BUFFER_SIZE) buffers.  There are eight callers
(SMB worker functions) which are primarily affected by this change:

TreeDisconnect, uLogoff, Close, findClose, SetFileSize, SetFileTimes,
Lock and PosixLock

      [CIFS] Fix cifsd so shuts down when signing fails during mount · a013689d
      由 Steve French 提交于 
      Fixes two problems:
1) we dropped down to negotiating lanman if we did not recognize the
mechanism (krb5 e.g.)
2) we did not stop cifsd (thus will fail when doing rmod cifs with
slab free errors) when we fail tcon but have a bad session (which is
the case in which signing is required but we don't allow signing on
the client)

It also turns on extended security flag in the header when passing
"sec=krb5" on mount command (although kerberos support is not done of
course)

      [CIFS] Add support for new POSIX unlink · 2d785a50
      由 Steve French 提交于 
      In the cleanup phase of the dbench test, we were noticing sharing
violation followed by failed directory removals when dbench
did not close the test files before the cleanup phase started.
Using the new POSIX unlink, which Samba has supported for a few
months, avoids this.
