[Kernel-packages] [Bug 2045384] Re: AppArmor patch for mq-posix interface is missing in jammy
No they cannot use 22-hwe/stable. I talked to this customer and they cannot accept kernel version change. (ABI interface and other minor changes maybe introduced by 6.2 kernel and they cannot take this risk) -- 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/2045384 Title: AppArmor patch for mq-posix interface is missing in jammy Status in linux package in Ubuntu: Incomplete Bug description: [ Impact ] mq-posix snapd interface does not work on Ubuntu Core 22. It results in permission denied even all interfaces are connected. Our brandstore customer is using posix message queue for IPC between snaps. They added mq-posix interface and connected them properly but getting permission denied error. The AppArmor patch for posix message queue created for other customer did not land in the standard jammy kernel. Userspace support for AppArmor message queue handling is already present in Ubuntu Core 22, it is just missing from the kernel. [ Test Plan ] * Create snaps using the posix-mq snapd interface on Ubuntu Core 22 or Classic 22.04 with the standard kernel. * Example snaps for testing: https://code.launchpad.net/~itrue/+git/mqtest-provider and https://code.launchpad.net/~itrue/+git/mqtest-client [ Where problems could occur ] * The patches already exist for 5.15 and have been used on other private customer kernels and all kernels released after 22.04, so there is already a good track record for this patchset and it shouldn't create any issues. [ Other Info ] * This is a time-sensitive issue for a paying customer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2045384/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
