cifs errors on build 378.55

[jon_s]

I'm using an RT-AC3200 with build 378.55.
Mounting a cifs share always returns an invalid argument:

# mount -t cifs //192.168.1.161/share /cifs1
mount: mounting //192.168.1.161/share on /cifs1 failed: Invalid argument

# mount -t cifs \\\\192.168.1.161\\share /cifs1
mount: mounting \\192.168.1.161\share on /cifs1 failed: Invalid argument

Searching the web, it seems this may be a problem with busybox. Has anyone else seen this issue?

Have you tried adding

-o "username=xxxx,password=yyyy"

Look in syslog, you might see something like this:

Sep 21 20:46:13 kernel:  CIFS VFS: No username specified

Yes, I have tried with and without the username/password options. Gives the same error.

Do you get any errors in syslog?

There are no errors in syslog. However, looking at strace output, it looks like the Kernel is returning the error:
mount("//192.168.1.161/temp", "/cifs1", "cifs", MS_MANDLOCK|MS_SILENT, "username=xyz,password=abc,ip=192"...) = -1 EINVAL (Invalid argument)
