[PATCH v4 0/9] Fix SECINFO procedure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

From: Bryan Schumaker <bjschuma@xxxxxxxxxx>

My initial SECINFO implementation was merged in 2.6.39, but accidentally
got disabled in 3.0.  These patches re-enable SECINFO as part of LOOKUP
and push it down to the v4 layer, instead of existing as an rpc_op (I
create a "submount" rpc_op instead, see patch 5).

I also noticed that SECINFO_NO_NAME was never run with the current xdr
decoding logic.  Patch 6 fixes this problem.

Changes in version 4:
- Reorder patches to fix the bug first and then clean up files

Changes in version 3:
- Don't define decode_secinfo_no_name() if CONFIG_NFS_V4_1 isn't set
- Move around function declerations in header files

Changes in version 2:
- Reorder the patches so I'm not doing cleanup in the beginning
- Don't pre-clone an rpc_clnt for nfs_clone_server, instead fix passing an
  rpc_authflavor_t through the nfs_clone_mount data.

Comments are appreciated!
