Modernize ocfs2
a project by goldwynr
Updated 19 days ago. 1 hackers ♥️. 1 follower.

Ocfs2 has gone into a stage of neglect and disrepair. Modernize the code to generate enough interest.

Goals: * Change the mount sequence to use fscontext * Move from using bufferhead to bio/folios * Use iomap * Run it through xfstests

    Improve UML page fault handler by ptesarik

    Description

    Improve UML handling of segmentation faults in kernel mode. Although such page faults are generally caused by a kernel bug, it is annoying if they cause an infinite loop, or panic the kernel. More importantly, a robust implementation allows to write KUnit tests for various guard pages, preventing potential kernel self-protection regressions.

    Goals

    Convert the UML page fault handler to use oops_* helpers, go through a few review rounds and finally get my patch series merged in 6.14.

    Linux on Cavium CN23XX cards by tsbogend

    Before Cavium switched to ARM64 CPUs they developed quite powerful MIPS based SOCs. The current upstream Linux kernel already supports some Octeon SOCs, but not the latest versions. Goal of this Hack Week project is to use the latest Cavium SDK to update the Linux kernel code to let it running on CN23XX network cards.

    Modularization and Modernization of cifs.ko for Enhanced SMB Protocol Support by hcarvalho

    Creator:
    Enzo Matsumiya ematsumiya@suse.de @ SUSE Samba team
    Members:
    Henrique Carvalho henrique.carvalho@suse.com @ SUSE Samba team

    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.
