freebsd stable - Nov 2013 - 10.0-BETA3: Unable to access files on SMB share

Hi All,

on fresh installation of 10.0-BETA3 it is unable to access files on Samba share:

# mount
[...]
//USER at HOSTING/DTEL-IX on /mnt/fs/dtel-ix (smbfs)

# cp /mnt/fs/dtel-ix/port_distribution.xls ./
cp: ./port_distribution.xls: Bad address

At the same time I get kernel messages:
smbfs_getpages: error 60
vm_fault: pager read error, pid 927 (cp)

Please advice,

thanks.

Sorry for breaking thread. I've read this ML via pipermail and
subscribed just now for this.

I'm surprised to know that smbfs was working on r255453.

For me, as I already sent PR kern/182963 and posted a thread in The
FreeBSD Forums, smbfs was not properly working in r255138 and later.
Same as stable/10, while r255136 (in head) works OK.

In my case, applying the diff I attached to kern/182963 fixes the issue.
The diff modifies timeout values in 2 lines, as r255138 changes
sb_timeo in struct sockbuf from int (unit of time is hz) to sbintime_t
(unit of time is 1/10^33 in seconds, as time in seconds is stored in
upper half of __int64_t), but sys/netsmb/smb_trantcp.c doesn't chase it.


The thread I created before kern/182963 is as follows:
