nfs: Enclose hostname in brackets when needed in nfs_do_root_mount

2012-05-07T15:53:18Z

commit 98a2139f4f4d7b5fcc3a54c7fddbe88612abed20 upstream. When hostname contains colon (e.g. when it is an IPv6 address) it needs to be enclosed in brackets to make parsing of NFS device string possible. Fix nfs_do_root_mount() to enclose hostname properly when needed. NFS code actually does not need this as it does not parse the string passed by nfs_do_root_mount() but the device string is exposed to userspace in /proc/mounts.

nfs: fix regression in handling of context= option in NFSv4

2012-01-05T15:42:40Z

Setting the security context of a NFSv4 mount via the context= mount option is currently broken. The NFSv4 codepath allocates a parsed options struct, and then parses the mount options to fill it. It eventually calls nfs4_remote_mount which calls security_init_mnt_opts. That clobbers the lsm_opts struct that was populated earlier. This bug also looks like it causes a small memory leak on each v4 mount where context= is used. Fix this by moving the initialization of the lsm_opts into nfs_alloc_parsed_mount_data. Also, add a destructor for nfs_parsed_mount_data to make it easier to free all of the allocations hanging off of it, and to ensure that the security_free_mnt_opts is called whenever security_init_mnt_opts is. I believe this regression was introduced quite some time ago, probably by commit c02d7adf. Cc: stable@vger.kernel.org Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

btrfs, nfs, apparmor: don't pull mnt_namespace.h for no reason...

2012-01-04T03:52:38Z

it's not needed anymore; we used to, back when we had to do mount_subtree() by hand, complete with put_mnt_ns() in it. No more... Apparmor didn't need it since the __d_path() fix. Signed-off-by: Al Viro

new helper: mount_subtree()

2011-11-17T03:00:34Z

takes vfsmount and relative path, does lookup within that vfsmount (possibly triggering automounts) and returns the result as root of subtree suitable for return by ->mount() (i.e. a reference to dentry and an active reference to its superblock grabbed, superblock locked exclusive). btrfs and nfs switched to it instead of open-coding the sucker.
