Pseudo needs to be aware of this function and create an intercept for it. 103813 1 richard.purdie 2026-01-12 17:51:03 +0000 For tar on stream9 we need to intercept the syscall too: https://git.yoctoproject.org/pseudo/tree/ports/linux/guts/syscall.c https://git.yoctoproject.org/pseudo/tree/ports/linux/guts/syscall.c 103814 2 richard.purdie 2026-01-12 17:52:12 +0000 https://bugzilla.yoctoproject.org/show_bug.cgi?id=16117 103894 3 mark.hatle 2026-01-15 00:55:56 +0000 psseudo master has a syscall intercept for SYS_openat2 that returns ENOSYS. This should unblock immediate users. Additionally, I've adapted 'openat' as a possible 'openat2' implementation. See: https://git.yoctoproject.org/pseudo/commit/?h=fray/master-wip&id=022e103f0b1223fb6557d730471196cb2223ac27 This is a first version. Once the function (not syscall) is mainstream, we'll likely want to have 'openat' call 'openat2', as well and adjust it to pass through whatever openat2 interface glibc ends up with, but until then this SHOULD work and is good enough for testing purposes. 103924 4 randy.macleod 2026-01-15 16:09:08 +0000 Lower to M+. We've got a patch to return ENOSYS for now and there is a plan for a proper implementation. 104982 5 paul 2026-04-08 09:45:48 +0000 Based on Zoltan's testing, it looks like we'll need full openat2() handling to build on Fedora 44 [1].

I am worried there may be chroot issues with that change though. 105335 8 richard.purdie 2026-04-30 20:58:30 +0000 https://git.yoctoproject.org/pseudo/commit/?id=6533a536f93a13ec39e5fd42e3385798729e093f and following commit.
