Definite -stable fodder, fortunately not going too far back. This is *not* all - there will be much bigger vfs pull request tomorrow." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: get rid of unprotected dereferencing of mnt->mnt_ns
| * get rid of unprotected dereferencing of mnt->mnt_nsAl Viro2013-02-221-12/+17
| | | | | | | | | | | | | | | | | | | | It's safe only under namespace_sem or vfsmount_lock; all places in fs/namespace.c that want mnt->mnt_ns->user_ns actually want to use current->nsproxy->mnt_ns->user_ns (note the calls of check_mnt() in there).

I do my best to document that if you care about limiting your unprivileged users that when you have the user namespace support enabled you will need to enable memory control groups. There is a minor bug fix to prevent overflowing the stack if someone creates way too many user namespaces. The bulk of the changes are a continuation of the kuid/kgid push down work through the filesystems. These changes make using uids and gids typesafe which ensures that these filesystems are safe to use when multiple user namespaces are in use. The filesystems converted for 3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The changes for these filesystems were a little more involved so I split the changes into smaller hopefully obviously correct changes. XFS is the only filesystem that remains. I was hoping I could get that in this release so that user namespace support would be enabled with an allyesconfig or an allmodconfig but it looks like the xfs changes need another couple of days before it they are ready." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (93 commits) cifs: Enable building with user namespaces enabled. cifs: Convert struct cifs_ses to use a kuid_t and a kgid_t cifs: Convert struct cifs_sb_info to use kuids and kgids cifs: Modify struct smb_vol to use kuids and kgids cifs: Convert struct cifsFileInfo to use a kuid cifs: Convert struct cifs_fattr to use kuid and kgids cifs: Convert struct tcon_link to use a kuid. cifs: Modify struct cifs_unix_set_info_args to hold a kuid_t and a kgid_t cifs: Convert from a kuid before printing current_fsuid cifs: Use kuids and kgids SID to uid/gid mapping cifs: Pass GLOBAL_ROOT_UID and GLOBAL_ROOT_GID to keyring_alloc cifs: Use BUILD_BUG_ON to validate uids and gids are the same size cifs: Override unmappable incoming uids and gids nfsd: Enable building with user namespaces enabled. nfsd: Properly compare and initialize kuids and kgids nfsd: Store ex_anon_uid and ex_anon_gid as kuids and kgids nfsd: Modify nfsd4_cb_sec to use kuids and kgids nfsd: Handle kuids and kgids in the nfs4acl to posix_acl conversion nfsd: Convert nfsxdr to use kuids and kgids nfsd: Convert nfs3xdr to use kuids and kgids ...

Remove all initializations of the deprecated posic_acl_entry e_id field. Which is not present when user namespaces are enabled. Split find_uid into two functions find_uid and find_gid that work in a typesafe manner. In nfs4xdr update nfsd4_encode_fattr to deal with the changes in struct nfs4_ace. Rewrite nfsd4_encode_name to take a kuid_t and a kgid_t instead of a generic id and flag if it is a group or a uid. Replace the group flag with a test for a valid gid.

Modify nfsd4_encode_aclname to take an ace instead of taking the fields of an ace broken out. This allows it to detect if the ace is for a user or a group and to pass the appropriate value while still being typesafe. Cc: "J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Both qd_alloc and qd2offset perform the exact same computation to get an index from a gfs2_quota_data. Make life a little simpler and factor out this index computation. Cc: Steven Whitehouse <swhiteho@redhat.com> Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a quota is queried return the uid or the gid in the mapped into the caller's user namespace. In addition perform the munged version of the mapping so that instead of -1 a value that does not map is reported as the overflowuid or the overflowgid.

| * | gfs2: Remove improper checks in gfs2_set_dqblk.Eric W. Biederman2013-02-131-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In set_dqblk it is an error to look at fdq->d_id or fdq->d_flags. Userspace quota applications do not set these fields when calling quotactl(Q_XSETQLIM,...), and the kernel does not set those fields when quota_setquota calls set_dqblk. gfs2 never looks at fdq->d_id or fdq->d_flags after checking to see if they match the id and type supplied to set_dqblk. No other linux filesystem in set_dqblk looks at either fdq->d_id or fdq->d_flags. Therefore remove these bogus checks from gfs2 and allow normal quota setting applications to work.
