[Touch-packages] [Bug 1861177] Re: seccomp_rule_add is very slow
As discussed on IRC, I have reviewed all the SRUs. They looked correct from my POV (although I guess I'd appreciate a second opinion from the security team). Since we want to include those in the -security pockets as well, I have uploaded all of them to a security-only Bileto PPA. I have confirmed via the build logs that only -security is enabled. The PPA can be found here: https://launchpad.net/~ci-train-ppa- service/+archive/ubuntu/4143/+packages Once the packages build correctly, I will bin-copy them to -proposed and remove the source uploads from the upload queues. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libseccomp in Ubuntu. https://bugs.launchpad.net/bugs/1861177 Title: seccomp_rule_add is very slow Status in snapd: Invalid Status in libseccomp package in Ubuntu: In Progress Status in libseccomp source package in Xenial: In Progress Status in libseccomp source package in Bionic: In Progress Status in libseccomp source package in Eoan: In Progress Status in libseccomp source package in Focal: In Progress Status in libseccomp source package in Groovy: In Progress Bug description: [IMPACT] There is a known and patched issue with version 2.4 of libseccomp where certain operations have a large performance regression.
