Description

Split cifs.ko in 2 separate modules; one for SMB 1.0 and 2.0.x, and another for SMB 2.1, 3.0, and 3.1.1.

Goals

Primary

Start phasing out/deprecation of older SMB versions

Secondary

  • Clean up of the code (with focus on the newer versions)
  • Update cifs-utils
  • Update documentation
  • Improve backport workflow (see below)

Technical details

Ideas for the implementation.

  • fs/smb/client/{old,new}.c to generate the respective modules
    • Maybe don't create separate folders? (re-evaluate as things progresses!)
  • Remove server->{ops,vals} if possible
  • Clean up fs_context.* -- merge duplicate options into one, handle them in userspace utils
  • Reduce code in smb2pdu.c -- tons of functions with very similar init/setup -> send/recv -> handle/free flow
  • Restructure multichannel
    • Treat initial connection as "channel 0" regardless of multichannel enabled/negotiated status, proceed with extra channels accordingly
    • Extra channel just point to "channel 0" as the primary server, no need to allocate an extra TCPServerInfo for each one
  • Authentication mechanisms
    • Modernize algorithms (references: himmelblau, IAKERB/Local KDC, SCRAM, oauth2 (Azure), etc.
