Tim, we've got the same train of thought :) I'm planning to keep an on on the upstream thread and if no solution presents itself I'll revert this patch prior to our final upload before kernel freeze. ** Changed in: linux (Ubuntu Natty) Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/731878 Title: shutdown(2) behavior changed in kernel -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Leann - If upstream doesn't come up with a fix prior to kernel freeze, then I suggest that we revert this patch in advance of our initial release. The deficiency that this patch addresses has existed since 2.6.34.

I've tested and confirmed that commit c191a836a908d1dd6b40c503741f91b914de3348 is indeed the root cause of the issue.

I'll work on building a test kernel with commit c191a836a908d1dd6b40c503741f91b914de3348 reverted so we can confirm it's the culprit.

[Bug 731878] Re: shutdown(2) behavior changed in kernel
This appears to be a behavioral change to the shutdown(2) function. The socket gets only partially shut down. It's like "close()" was called instead of "shutdown()" which is supposed to kill the socket everywhere. ** Summary changed: - amavis force-reload crashes amavis + shutdown(2) behavior changed in kernel ** Package changed: amavisd-new (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Changed in: linux (Ubuntu) Milestone: None => ubuntu-11.04-beta-2 ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Canonical Kernel Team (canonical-kernel-team) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/731878 Title: shutdown(2) behavior changed in kernel -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
