For the version which doesn't behave like openat, you need CAP_SYS_ADMIN so in most of our use cases, it would never success so is less likely to get called in the first place. 106724 2 frezidok1 2026-09-04 07:57:49 +0000 Do we need syscall implementation for this as well? glibc's open_tree() appeared only in glibc 2.36, while kernel supports it from 5.2, so syscall(SYS_open_tree) may be common use case. 106733 3 richard.purdie 2026-09-04 16:42:14 +0000 I was just looking at your patches, thanks! I think unless we find such usage in the wild, we probably don't need to do that. The key thing is to make sure at least glibc is wrapped as hopefully most users would use that first over direct syscalls. 106736 4 frezidok1 2026-09-04 16:53:32 +0000 I was investigating the open_tree_attr thing and found out that add syscall coverage is easier than I expected, so I did it too. It helped me to find some drawbacks in my first implementation, so I think it won’t hurt. 107169 5 richard.purdie 2026-10-22 15:22:49 +0000 Thanks, Dmitry, sorry about the delays but we got there! https://git.yoctoproject.org/pseudo/commit/?id=609e59be33bcc1d614f1347514a9ea4042b56f20
