[PATCH] fuse: fix Oops in lookup

2006-11-25T21:28:33Z

Fix bug in certain error paths of lookup routines. The request object was reused for sending FORGET, which is illegal. This bug could cause an Oops in 2.6.18. In earlier versions it might silently corrupt memory, but this is very unlikely. These error paths are never triggered by libfuse, so this wasn't noticed even with the 2.6.18 kernel, only with a filesystem using the raw kernel interface. Thanks to Russ Cox for the bug report and test filesystem. Signed-off-by: Miklos Szeredi Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] eCryptfs: CIFS nlink fixes

2006-11-16T19:43:38Z

When CIFS is the lower filesystem, the old lower dentry needs to be explicitly dropped from inside eCryptfs to force a revalidate. In addition, when CIFS is the lower filesystem, the inode attributes need to be copied back up from the lower inode to the eCryptfs inode on an eCryptfs revalidate.
