Hi, I'm a longer term user who normally builds a custom kernel, using the aufs-standalone branch, and I build the aufs piece without the option of standalone modules.
I've previously been using kernel 6.1 without an issue. I upgraded to kernel 6.6.10 and can no longer mount aufs. Kernel was built with gcc-13. Aufs branch was aufs6.6, which I think is dated 31 october 2023. I make a trivial reproduction on my rootfs which is using xfs mkdir /root/aufs/l1 mkdir /root/aufs/l2 mkdir /root/aufs/m mount -t aufs -o noxino,br=/root/aufs/l1:/root/aufs/l2 none /root/aufs/m This succeeds, but grunt ~/aufs # ls -al /root/aufs/m ls: cannot access '/root/aufs/m': Operation not permitted grunt ~/aufs # ls -al /root/aufs/ ls: cannot access '/root/aufs/m': Operation not permitted total 8 drwxr-xr-x 5 root root 35 Jan 16 13:52 . drwx------ 9 root root 4096 Jan 16 13:52 .. drwxr-xr-x 4 root root 66 Jan 16 13:53 l1 drwxr-xr-x 2 root root 6 Jan 16 13:52 l2 d????????? ? ? ? ? ? m Something is broken with the mount I don't see anything in dmesg. Does anyone else see this problem? Ed W
