Subject: ecryptfs lock loop
Date: Tue, 14 Apr 2009 21:36:04 +0200	[thread overview]
Message-ID: <49E4E5A4.80109@gmail.com> (raw)

Hi,

one student (in CC) found out a suspicioous locking dependence in
ecryptfs code while debugging/running a static lockdep analyzer.

I'm unable to say whether it is only a theoretical issue or a real bug,
any ideas?

Here it comes:

function ecryptfs_send_message:
------------------------------
ecryptfs_daemon_hash_mux <- ecryptfs_msg_ctx_lists_mux
(in function ecryptfs_send_message_locked)

function ecryptfs_wait_for_response:
-----------------------------------
cryptfs_msg_ctx_lists_mux <- msg_ctx->mux

function ecryptfs_process_response:
----------------------------------
msg_ctx->mux <- ecryptfs_daemon_hash_mux


<- means lock dependency
