cifs: convert prefixpath delimiters in cifs_build_path_to_root

2011-08-16T01:31:36Z

commit f9e8c45002cacad536b338dfa9e910e341a49c31 upstream. Regression from 2.6.39... The delimiters in the prefixpath are not being converted based on whether posix paths are in effect.

cifs: cope with negative dentries in cifs_get_root

2011-08-16T01:31:36Z

commit 80975d21aae2136ccae1ce914a1602dc1d8b0795 upstream. The loop around lookup_one_len doesn't handle the case where it might return a negative dentry, which can cause an oops on the next pass through the loop. Check for that and break out of the loop with an error of -ENOENT if there is one.

CIFS: Fix oops while mounting with prefixpath

2011-08-05T04:58:33Z

commit f5bc1e755d23d022bf948904386337fc3e5e29a8 upstream. commit fec11dd9a0109fe52fd631e5c510778d6cbff6cc caused a regression when we have already mounted //server/share/a and want to mount //server/share/a/b. The problem is that lookup_one_len calls __lookup_hash with nd pointer as NULL. Then __lookup_hash calls do_revalidate in the case when dentry exists and we end up with NULL pointer deference in cifs_d_revalidate: if (nd->flags & LOOKUP_RCU) return -ECHILD; Fix this by checking nd for NULL.

Add missing ->i_mutex, convert to lookup_one_len() instead of (broken) open-coded analog, cope with getting something like a//b as relative pathname. Simplify the hell out of it, while we are there... Signed-off-by: Al Viro Reviewed-by: Jeff Layton
