User-Visible OpenAFS Changes

OpenAFS 1.8.16pre1

  All platforms

    * A build error has been fixed for platforms with glibc 2.43 or later and C
      compilers which are enforcing ISO C23 rules. This change fixes a
      build error on Ubuntu 26.04 development releases (16751).

    * A build error during parallel builds has been fixed (16758).

  Linux client

    * A bug that caused dentries to not properly be revalidated on Linux 6.17
      has been fixed. The bug manifested as not seeing filename changes made on
      other clients; that is, files being renamed, created, or deleted (16729).

    * A Linux kernel function for folio migration has been implemented,
      silencing a kernel log message warning that a fallback implementation
      was used instead (16709).

    * A potential bug (with no known path to trigger it) has been fixed where
      a recursive writeback operation left page dirty flags in an inconsistent
      state (potentially leading to data corruption) or leaked a folio
      reference (in effect, leaking memory) (16702).

    * A Linux kernel log message is issued if an unexpected recursive call to
      writeback occurs. While this condition should not cause any problems,
      the message should be reported. (16705).

    * Support for Linux kernel 6.18 has been added (16701, 16703, 16704).

    * Support for Linux kernel 6.19 has been added (16707, 16708).

    * Support for Linux kernel 7.0 has been added (16738).

  MacOS client

    * Several binaries (bos, cmdebug, fs, xstat_cm_test, xstat_fs_test, and
      backup) are now distributed as x86_64-only thin binaries, instead of as
      universal binaries like all other commands. On arm64, these commands will
      still run automatically via Rosetta2. This avoids an issue where those
      binaries experienced segfaults in LWP in arm64 code. The original
      universal binaries for these utilities are distributed in
      /Library/OpenAFS/Tools/bin.orig/. (16753)
