The major news, as per the title, is that a port to FreeBSD arm64 (or aarch64) is now ready. The next steps are to get it reviewed and pushed upstream.

Valgrind 3.23 is due out at the end of April 2024 and devel/valgrind will be updated shortly after that.

devel/valgrind-devel will get an update as soon as I have pushed the changes for arm64.

--track-fds=yes now checks for and warns about attempts to close a file descriptor more than once. Handling of closefrom has been improved to use this feature.

There are some important fixes for FreeBSD 15, in particular handling the new libsys.

Here is a list of smaller bugfixes:

  • Support for FreeBSD 13.3 has been added.

  • Added a redirect for reallocarray.

  • Several fixes for aio* functions.

  • Added a redirect for memccpy.

  • There is a fix for _umtx_op OP_ROBUST_LISTS.

  • Added redirects for C23 free_sized and free_aligned_sized.

  • Correctly propagate the ELF stack protection flags to the guest stack that Valgrind synthesizes.

  • Fixes for --sanity-level-3 and above (only used for Valgrind self-testing at runtime).

  • Several fixes to checking done for semctl.

  • Fixed argument checking for utrace.

  • Fixed argument checking for clock_nanosleep.
