15.4 kernel 5.14.21-150400.24.38-default not respecting vers=1.0 for OS/2 LAN connectivity
by Felix Miata 06 Jan '23

5.14.21-150400.24.38-default boots, but I can't use it, because OS/2 connectivity is a must. 5.14.21-150400.24.33-default solves the problem, keeps OS/2 connected. What changed this time? I looked in the 24.38 changlog since 24.33 release and didn't spot anything. The vers=1.0 hit in the error message doesn't seem could apply, since it's already being used: /etc/fstab includes: //os2/G /smbmnt/os2/G cifs ro,credentials=/etc/samba/os2.cred,noserverino,sec=lanman,vers=1.0,servern=OS2,domain=PEERS,port=139,dir_mode=0555,file_mode=0664,noauto 0 0 # alias | grep mountos2 alias mountos2='mount //os2/G' # mountos2 mount error: Server abruptly closed the connection. This can happen if the server does not support the SMB version you are trying to use. The default SMB version recently changed from SMB1 to SMB2.1 and above. Try mounting with vers=1.0. mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg) With the older kernel and working as expected, the journal contained the following: ## kernel 24.33 - OK # journalctl -b | grep -i -C3 cifs > Jan 01 03:47:59 at-spi-bus-launcher[1378]: SpiRegistry daemon is running with well-known name - org.a11y.atspi.Registry Jan 01 03:48:06 kernel: FS-Cache: Loaded Jan 01 03:48:06 kernel: Key type dns_resolver registered Jan 01 03:48:06 kernel: FS-Cache: Netfs 'cifs' registered for caching Jan 01 03:48:06 kernel: Key type cifs.spnego registered Jan 01 03:48:06 kernel: Key type cifs.idmap registered Jan 01 03:48:06 kernel: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: VFS: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: Attempting to mount \\mazda\E Jan 01 03:48:06 kernel: CIFS: VFS: Send error in QFSAttributeInfo = -95 Jan 01 03:48:06 kernel: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: VFS: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: Attempting to mount \\mazda\G Jan 01 03:48:06 kernel: CIFS: VFS: Send error in QFSAttributeInfo = -95 Jan 01 03:48:06 kernel: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: VFS: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: Attempting to mount \\mazda\I Jan 01 03:48:06 kernel: CIFS: VFS: Send error in QFSAttributeInfo = -95 Jan 01 03:48:06 kernel: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: VFS: Use of the less secure dialect vers=1.0 is not recommended unless required for access to very old servers Jan 01 03:48:06 kernel: CIFS: Attempting to mount \\mazda\J Jan 01 03:48:06 kernel: CIFS: VFS: Send error in QFSAttributeInfo = -95 ...
