Ok, a plain jammy rebuild in a launchpad ppa failed: 2022-06-17 14:18:27 0 [Warning] mariadbd: io_uring_queue_init() failed with ENOMEM: try larger memory locked limit, ulimit -l, or https://mariadb.com/kb/en/systemd/#configuring-limitmemlock under systemd (262144 bytes required)
The binary package that is currently in jammy was probably rebuilt before the lto changes I'm guessing, because it's not affected by this. So I wonder how current jammy users could be affected by this (besides the rebuild). Let's see if Michal has something to say about my comment #15. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1970634 Title: FTBFS: mariadb fails to start due to low MEMLOCK limit Status in mariadb-10.6 package in Ubuntu: Fix Released Status in systemd package in Ubuntu: Confirmed Status in mariadb-10.6 source package in Jammy: Triaged Status in systemd source package in Jammy: In Progress Bug description: <rbasak> ahasenack: IIRC, originally Launchpad was FTBFSing on mariadb that included io_uring support because upstream were doing a build time test for io_uring (and I think still are), which is wrong because it should be done at runtime since the lack of io_uring availablity at build time doesn't tell us about its availablity at runtime. <rbasak> But then the Launchpad builders got updated to a newer release and therefore a newer kernel that supported it. <rbasak> AIUI, that's how we ended up with a successful build in the Jammy release pocket (of 10.6). <ahasenack> I think the lp builders are using the focal hwe kernel <ahasenack> 5.4.0-something <ahasenack> let me check that build log <rbasak> But then something changed that caused this current FTBFS, and I haven't tracked down what that is. <ahasenack> hm, both are 10.6.7 <ahasenack> release and proposed <rbasak> What puzzles me is that if the root cause is a memlock rlimit issue then why did it work before? <rbasak> So since there's a contradiction somewhere, maybe one or more of my "facts" above is wrong. <ahasenack> this is the current failure <ahasenack> 2022-04-14 8:11:49 0 [Warning] mariadbd: io_uring_queue_init() failed with ENOMEM: try larger memory locked limit, ulimit -l, or https://mariadb.com/kb/en/systemd/#configuring-limitmemlock under systemd (262144 bytes required) <ahasenack> and ulimit -l confirms that the limit is lower <ahasenack> Max locked memory 65536 65536 bytes <ahasenack> just 64kbytes <rbasak> Yeah but then how did the release pocket build work? <ahasenack> either the limit was different back then <ahasenack> or ... stuff To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mariadb-10.6/+bug/1970634/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
