FreeBSD git weekly: 2026-05-04 to 2026-05-10

Introduction

This is a display of mostly-automatically-classified git commits from 2026-05-04 to 2026-05-10.

This report is still in progress.

Table of contents and commits per category:

Highlighted commits Expand section Collapse section

For extra visibility, these are copies of commits found in other sections. Most (if not all) come from the commit message containing "Relnotes:", or commits modifying UPDATING.

-- no commits in this category this week --

Userland programs Expand section Collapse section

Commits about commands found in man section 1 (other than networking).

-- no commits in this category this week --

Documentation Expand section Collapse section

Man pages, release notes, etc.

The current text fails to draw the reader's attention to the fact that
VIS_SAFE essentially exempts certain characters from being encoded.

While here, fix some markup nits.

Hardware support Expand section Collapse section

Hardware drivers and architecture-specific code.

Reported by:  ziaee@
Fixes:  https://cgit.freebsd.org/src/commit/?id=fd8d34ce27 ("dpaa: Migrate from NCSW base to a home-grown driver")

Reported by:  ziaee@
Fixes:  https://cgit.freebsd.org/src/commit/?id=d22051b18 ("iicbus/rtc: Add driver for the Ricoh rs5c372 RTC")

Older SMC firmware exposed AUPO as a Wake-on-LAN control. On updated
firmware, the key controls automatic power-on when AC power is restored
after a power loss; WoL is handled by the GBE controller instead.
Rename the sysctl to reflect the current semantics. No compatibility
alias is provided as the sysctl has not appeared in any release.

Filesystems Expand section Collapse section

The client tells the server how many callback slots
it can handle in the callback session.  However, the
NFSv4.1/4.2 server can only handle a maximum of
NFSV4_SLOTS slots.  This patch clips the client's
value to that, to avoid using too high a slot#
for a callback.

Fortunately, I do not know of an extant client that
specifies a value greater than NFSV4_SLOTS, so this
patch is not really needed, as yet.  Also, the client
rarely uses a slot# above 0 when doing callbacks.

Kernel Expand section Collapse section

Kernel stuff (other than networking, filesystems, and drivers).

This helps ensure that overflows will trigger a panic instead of
silently corrupting adjacent buffers, as happened in SA-26:13.exec.

Extend kmap_alloc_wait() to support allocation of guard pages on both
sides of a KVA allocation.  Modify the exec_map setup accordingly.  Add
the "vm.exec_map_guard_pages" tunable to provide control over the guard
page allocations.

Build system Expand section Collapse section

Commit c4f08d46c7f7 moved the symlinks for the LLVM binutils from LLVM
itself to the toolchain (usr.bin/clang/toolchain), but did not remove
the links for /usr/bin/gcov and /usr/bin/objdump from the llvm version,
meaning we installed them twice, once in the clang package and once in
the toolchain package.

Remove the links from the llvm version and move the MLINKs to toolchain,
which is where the other MLINKs dwell.

While here, fix toolchain to use the correct build option for llvm-cov,
MK_LLVM_COV.

Fixes: https://cgit.freebsd.org/src/commit/?id=c4f08d46c7f7 ("llvm-*: Move all LLVM_BINUTILS symlinks to toolchain package")

Technical notes

Dates:

• The dates are "approximate" because git has no record of exactly when each commit was added. The "author date" and "commit date" are text fields controlled by each committer, not the actual date the commit reaches cgit.freebsd.org/src. Git accurately records the order of commits, but not their dates.

Automatic grouping:

• "Commit & revert pair" groups were automatically grouped when a commit's (full) message contained

  This reverts commit \\b([0-9a-fA-F]{40})\\b

  and the hash was found in this week's commits.
• "Commit group #" groups were automatically grouped when 3 or more consecutive commits by the same author had the same category and summary prefix.

Automatic categories:

• Commits were (mostly) automatically classified based on regex pattern-matching on the commit's modified files, summary, or the whole commit message. The goal is to have the system automatically classify 95% of the commits, with 95% accuracy; then we'll manually check the results and fix the incorrectly-classified and unclassified commits.
