Bug#833989: (no subject)
Package: src:linux
Version: 3.16.7-ckt25-2+deb8u3
Severity: important
Hai, i have a problem with the current running kernel on jessie.
This involves Fix badlock regression for guest mounts.
The problem is : mount with -o guest can fail to Samba servers when patched for badlock.
I found the patch also in the upstream 4.7 kernel
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5a4f7e8e7ff5e81f57b08797cca41d307878dfc7
but this is a 2.08 to 2.09 commit.
Debian Jessie has cifs.ko 2.03, and samba recommends also at least 2.04 for best performance.
https://wiki.samba.org/index.php/LinuxCIFSKernel
kernel 4.7 : Cifs.ko version updated to 2.09.
Minor fixes: including NetApp DFSpathname issue and SPNEGO fix. Persistent handle reconnect fixes
Can this be backports into the stable kernel, that would help a lot of people.
Thanks!
