There are locking issues in the Hurd's libraries.

# Original [[community/GSoC]] Task Description
[[!inline pages=community/gsoc/project_ideas/libdiskfs_locking feeds=no]]
# ext2fs Deadlock
[[ext2fs_deadlock]].
# Formal Verification
Methods of [[formal_verification]] should be applied to get an understanding of
the behavior of the locking logic. There are tools for formal
verification/[[code_analysis]] that can likely help here.
There is a [[!FF_project 278]][[!tag bounty]] on this task.

<Steap> youpi: can you think of a locking error recently fixed in the
translators ? I'd like to try a Coccinelle script on a real-world example
<youpi> 0b6286a3c5eb86e3cca72d0840fc009855e4fba5 for instance
<youpi> or a60414ee7fdabb2bdfb17fe82b9a09f811bd2de0
<youpi> or b8082aab5049f753abd720a5ef6a113e2acef911
<Steap> thx, I think I might have caught a few double unlocks, I'll send
patches/bug reports this week-end
<youpi> oh, good :)
<tschwinge> Steap: Great -- looking forward to that!
