[Kernel-packages] [Bug 1205741] Re: The route metrics added ip route are not being inherited by route cache entries
Unfortunately in my haste to verify this, I bungled my test of -55 and managed to pull down the wrong source for -55 as well. Now that I have corrected both those mistakes, I can verify that the code for the fix is in -55 and the code for the fix functions properly. Sorry about that. ** Tags removed: verification-failed ** Tags added: verification-done -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1205741 Title: The route metrics added ip route are not being inherited by route cache entries Status in “linux” package in Ubuntu: Fix Committed Bug description: There is a bug in the the management of inet peers which prevents route metrics like initcwnd from being inherited by route cache entries.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- precise' to 'verification-done-precise'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

I just downloaded linux-image-3.2.0-55-generic from -proposed and the bug is still in this version. I inspected the source for linux- image-3.2.0-55-generic and I see no evidence that the patches cited above have been applied. There is no implementation or invocation of inetpeer_invalidate_tree or any of the supporting code for it. I also looked at the latest upstream 3.2 (3.2.51) and the fix isn't in that code either. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1205741 Title: The route metrics added ip route are not being inherited by route cache entries Status in “linux” package in Ubuntu: Fix Committed Bug description: There is a bug in the the management of inet peers which prevents route metrics like initcwnd from being inherited by route cache entries.

Joe, These three seem to be relevant. https://git.kernel.org/cgit/linux/kernel/git/stable/linux- stable.git/commit/?h=linux-3.5.yid=5faa5df1fa2024bd750089ff21dcc4191798263d https://git.kernel.org/cgit/linux/kernel/git/stable/linux- stable.git/commit/?h=linux-3.5.yid=e304dfdb030bab29888151021843bd9e1743a535 https://git.kernel.org/cgit/linux/kernel/git/stable/linux- stable.git/commit/?h=linux-3.5.yid=55432d2b543a4b6dfae54f5c432a566877a85d90 In particular, the first one adds the mechanism to invalidate the inetpeer tree when the route cache is invalidated because of a fib metric change. The second is a grand netdev merge. The third seems to be an essential bug fix that prevents reference to freed inetpeer entries. tim On Thu, 2013-08-08 at 17:38 +, Joseph Salisbury wrote: Do you happen to know the upstream SHA1 that fixes this bug in 3.5? ** Changed in: linux (Ubuntu) Importance: Undecided = Medium ** Tags added: kernel-da-key -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1205741 Title: The route metrics added ip route are not being inherited by route cache entries Status in “linux” package in Ubuntu: Confirmed Bug description: There is a bug in the the management of inet peers which prevents route metrics like initcwnd from being inherited by route cache entries.
