LinuxSMB3 build backport

From SambaWiki

To view the list of patches which are included in the backports, see

To build the current (all relevant patches to cifs.ko that are accepted in mainline Linux, ie all CIFS/SMB3 fixes and features except those that are the result of global changes to the kernel or the VFS interface) cifs.ko:

[verify which branch you want to check out, which kernel you are trying to build]

  • cat /proc/version (to see what kernel you are running)

[if you do not have the kernel headers installed they can be downloaded e.g. from;O=D]

  • git branch (to see the cifs backport branches, currently 4.9 through 4.15)
  • git checkout 4.11-full-backport (as an example if you were trying to build for 4.11 kernel)

[verify that you are booted to a matching kernel version, in this case some version of 4.11 e.g. cat /proc/version]

  • cd fs/cifs
  • make C=1 -C /usr/src/linux-headers-`uname -r` M=`pwd` modules
  • sudo modprobe cifs (if needed, e.g. to load any required loadable module dependencies for cifs.ko)
  • sudo rmmod cifs
  • sudo insmod ./cifs.ko (to load the module built a few steps above)
  • Enjoy ... (and test ... let us know on the mailing list if any problems)
