[PATCH 0/3] NFS: Fix SECINFO processing regression

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

 



From: Andy Adamson <andros@xxxxxxxxxx>

Iterate over multiple flavors returned by SECINFO. If RPC_AUTH_GSS is in the
secinfo list, fully test (get and auth, credential, and gss_context)

Fix some error paths.

Version 2:
- Responded to Trond's comments. Cloned an RPC client for each flavor to test
which creates an rpc_auth. Use rpcauth_lookupcred() to create a cred for the
user (and gss_context for gss).

- Removed nfs4_negotiate_security from nfs4_submount as is was just called
from nfs4_proc_lookup_mountpoint.


Testing: Minimal testing of the nfs_test_gss_flavor. Will run more tests after
the June 2014 bakeathon

Note: Can supply a patch for SECINFO_NO_name to use nfs4_negotiate_security.

-->Andy

Andy Adamson (3):
  NFS check the return of nfs4_negotiate_security in nfs4_submount
  NFS Return -EPERM if no supported or matching SECINFO flavor
  NFS test SECINFO RPC_AUTH_GSS pseudoflavors for support
