cifs filesystem not supported by the system 4.14.18 armv7


Hey,

I'm running SlackwareARM-current, installed with SARPi on a Raspberry Pi 3 and I ran into a problem with mounting SMB shares.
One share is hosted on Windows 7 and another one on Debian. Since I can access them from other Linux or Windows devices, I doubt there's a problem on the server side.

However, when I try:
Code:
# mount -t  cifs -o user=myself,ro //192.168.178.11/myself/mnt/tmp/
Password for myself@//192.168.178.11/myself:
mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
cifs-utils-6.7-arm-1 is installed by default, and "mount.cifs --help" displays some output.

Code:
# cat /proc/filesystems
nodev   sysfs
nodev   rootfs
nodev   ramfs
nodev   bdev
nodev   proc
nodev   cpuset
nodev   cgroup
nodev   cgroup2
nodev   tmpfs
nodev   devtmpfs
nodev   configfs
nodev   debugfs
nodev   tracefs
nodev   sockfs
nodev   pipefs
nodev   rpc_pipefs
nodev   devpts
        ext3
        ext2
        ext4
        vfat
        msdos
nodev   nfs
nodev   nfs4
nodev   autofs
        f2fs
nodev   mqueue
Looks like it's not available in the kernel?

Code:
# cat /boot/version-kernel_sarpi3.txt
Package: kernel_sarpi3-4.14.18_arm-armv7-1_slackcurrent_10Feb18_sp1.txz
Download: http://sarpi.co.uk/index.php?p=downloads
Build date: 2018-02-10 19:35:26
Git revision: 5e2d4ac539f8
Can I do something to enable cifs myself? Hints would be welcome
And.. is this by design? Or is CIFS not compatible to ARMv7 (samba is running fine though)?

On my current rpi3

Code:
modprobe configs
creates /proc/config.gz
Code:
zcat /proc/config.gz > config.txt
In config.txt I see CONFIG_CIFS=m

What does your above show?

If same then maybe?
Code:
modprobe cifs

Thanks for taking the time reply, glorsplitz.

Code:
# modprobe configs
modprobe: FATAL: Module configs not found in directory /lib/modules/4.14.18-v7-arm
However, there's a /proc/config.gz, its date indicates it was created on startup, so I checked that one, maybe it helps anyway. Heres what's in there for cifs:
Code:
# zcat /proc/config.gz | grep -i cifs
CONFIG_CIFS=m
# CONFIG_CIFS_STATS is not set
CONFIG_CIFS_WEAK_PW_HASH=y
CONFIG_CIFS_UPCALL=y
CONFIG_CIFS_XATTR=y
CONFIG_CIFS_POSIX=y
CONFIG_CIFS_ACL=y
CONFIG_CIFS_DEBUG=y
# CONFIG_CIFS_DEBUG2 is not set
# CONFIG_CIFS_DEBUG_DUMP_KEYS is not set
CONFIG_CIFS_DFS_UPCALL=y
# CONFIG_CIFS_SMB311 is not set
CONFIG_CIFS_FSCACHE=y
It states "CONFIG_CIFS=m", however loading the module fails:
Code:
# modprobe cifs
modprobe: FATAL: Module cifs not found in directory /lib/modules/4.14.18-v7-arm
I don't even have the specified directory "/lib/modules/", now this is surprising.
I fetched kernel-modules-sarpi3-4.14.18-armv7-1_slackcurrent_10Feb18_sp1.txz from the sarpi project page and installed it. Now cifs is working like a charm!
Thanks for your help!

It seems I've missed to install the packages listed here: http://sarpi.co.uk/index.php?p=configboot
I hope that didn't break more . I'll install the rest right now.
