Hi, the autopkgtests for autofs started to fail in Ubuntu in the s390x architecture only. The scenario is an authenticated localhost cifs mount. When I try it, I get: root@j-s390x:~# l /cifs/localhost ls: cannot access '/cifs/localhost': No such file or directory I get this in syslog: Jan 4 12:52:48 j-s390x automount[1969]: mount_autofs_offset: failed to mount offset trigger at Jan 4 12:52:48 j-s390x automount[1969]: message repeated 2 times: [ mount_autofs_offset: failed to mount offset trigger at ] Jan 4 12:52:48 j-s390x automount[1969]: mount_subtree: parse(sun): failed to mount offset triggers Jan 4 12:52:48 j-s390x kernel: [ 1582.465030] autofs4:pid:1991:validate_dev_ioctl: invalid path supplied for cmd(0xc018937e) Jan 4 12:52:48 j-s390x kernel: [ 1582.465306] autofs4:pid:1991:validate_dev_ioctl: invalid path supplied for cmd(0xc018937e) Jan 4 12:52:48 j-s390x kernel: [ 1582.465358] autofs4:pid:1991:validate_dev_ioctl: invalid path supplied for cmd(0xc018937e) Jan 4 12:52:48 j-s390x kernel: [ 1582.465405] autofs4:pid:1991:validate_dev_ioctl: invalid path supplied for cmd(0xc018937e) Jan 4 12:52:48 j-s390x kernel: [ 1582.465409] autofs4:pid:1991:validate_dev_ioctl: invalid path supplied for cmd(0xc018937e) Jan 4 12:52:48 j-s390x kernel: [ 1582.465412] autofs4:pid:1991:validate_dev_ioctl: invalid path supplied for cmd(0xc018937e) With 5.1.7, it works: root@j-s390x:~# l /cifs total 4.0K drwxr-xr-x 2 root root 0 Jan 4 12:55 . drwxr-xr-x 23 root root 4.0K Jan 4 12:55 .. root@j-s390x:~# l /cifs/localhost total 0 drwxr-xr-x 5 root root 0 Jan 4 12:55 . drwxr-xr-x 3 root root 0 Jan 4 12:55 .. drwxr-xr-x 2 root root 0 Dec 27 20:14 'print$' drwxr-xr-x 2 root root 0 Dec 27 20:15 private drwxr-xr-x 2 root root 0 Dec 27 20:15 pub root@j-s390x:~# l /cifs/localhost/private total 4.0K drwxr-xr-x 2 root root 0 Dec 27 20:15 . drwxr-xr-x 5 root root 0 Jan 4 12:55 .. -rwxr-xr-x 1 root root 64 Dec 29 17:16 hello-private.txt and syslog shows just: Jan 4 12:55:54 j-s390x kernel: [ 1768.290258] CIFS: Attempting to mount \\localhost\pub Jan 4 12:55:54 j-s390x kernel: [ 1768.318174] CIFS: Attempting to mount \\localhost\private Jan 4 12:55:54 j-s390x kernel: [ 1768.328218] CIFS: Attempting to mount \\localhost\print$ I have this config: root@j-s390x:~# cat /etc/auto.master|grep -vE "^($|#)" +dir:/etc/auto.master.d +auto.master /cifs /etc/auto.smb --timeout=180 The shares: [pub] path = /pub read only = no guest ok = yes [private] path = /private read only = no guest ok = no root@j-s390x:~# cat /etc/creds/localhost username=smbtest9614 password=9614 domain=WORKGROUP I see the 5.1.8 patches directory has a ton of patches, is this a known issue already perhaps? Or do you have any other troubleshooting tips? Thanks!
