NFS: Improve legacy idmapping fallback

2013-06-28T19:22:07Z

Fallback should happen only when the request_key() call fails, because this indicates that there was a problem running the nfsidmap program. We shouldn't call the legacy code if the error was elsewhere. Signed-off-by: Bryan Schumaker Signed-off-by: Trond Myklebust

NFSv4: Fix the string length returned by the idmapper

2013-03-20T20:45:16Z

Functions like nfs_map_uid_to_name() and nfs_map_gid_to_group() are expected to return a string without any terminating NUL character. Regression introduced by commit 57e62324e469e092ecc6c94a7a86fe4bd6ac5172 (NFS: Store the legacy idmapper result in the keyring).

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2013-02-27T04:16:07Z

Pull vfs pile (part one) from Al Viro: "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent locking violations, etc. The most visible changes here are death of FS_REVAL_DOT (replaced with "has ->d_weak_revalidate()") and a new helper getting from struct file to inode. Some bits of preparation to xattr method interface changes. Misc patches by various people sent this cycle *and* ocfs2 fixes from several cycles ago that should've been upstream right then. PS: the next vfs pile will be xattr stuff." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (46 commits) saner proc_get_inode() calling conventions proc: avoid extra pde_put() in proc_fill_super() fs: change return values from -EACCES to -EPERM fs/exec.c: make bprm_mm_init() static ocfs2/dlm: use GFP_ATOMIC inside a spin_lock ocfs2: fix possible use-after-free with AIO ocfs2: Fix oops in ocfs2_fast_symlink_readpage() code path get_empty_filp()/alloc_file() leave both ->f_pos and ->f_version zero target: writev() on single-element vector is pointless export kernel_write(), convert open-coded instances fs: encode_fh: return FILEID_INVALID if invalid fid_type kill f_vfsmnt vfs: kill FS_REVAL_DOT by adding a d_weak_revalidate dentry op nfsd: handle vfs_getattr errors in acl protocol switch vfs_getattr() to struct path default SET_PERSONALITY() in linux/elf.h ceph: prepopulate inodes only when request is aborted d_hash_and_lookup(): export, switch open-coded instances 9p: switch v9fs_set_create_acl() to inode+fid, do it before d_instantiate() 9p: split dropping the acls from v9fs_set_create_acl() ...

nfs: Convert idmap to use kuids and kgids

2013-02-13T14:15:29Z

Convert nfs_map_name_to_uid to return a kuid_t value. Convert nfs_map_name_to_gid to return a kgid_t value. Convert nfs_map_uid_to_name to take a kuid_t paramater. Convert nfs_map_gid_to_name to take a kgid_t paramater. Tweak nfs_fattr_map_owner_to_name to use a kuid_t intermediate value. Tweak nfs_fattr_map_group_to_name to use a kgid_t intermediate value. Which makes these functions properly handle kuids and kgids, including erroring of the generated kuid or kgid is invalid. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"
