[PATCH 0/2] Mark recipes whose point releases are fixes-only (3/3)

[daniel.turull]

From: Daniel Turull <daniel.turull@ericsson.com>

Last of three series opting recipes into UPSTREAM_STABLE_RELEASE_REGEX. The
first covered recipes whose upstream publishes a written stable-branch policy
and is merged; the second covered recipes qualifying on branch structure and
changelog evidence. This one covers the remaining smaller components, which
have lower CVE exposure but the same kind of evidence behind them.

[PATCH 1/2] lttng-ust: inherit upstream-stable-release-point

[daniel.turull]

From: Daniel Turull <daniel.turull@ericsson.com>

lttng-ust maintains a branch per minor series (stable-2.13 through
stable-2.16) and releases from several at once: 2.14.2 and 2.15.1 went out
the same day in May 2026, and three series together in February, 2.13.10,
2.14.1 and 2.15.0. So upgrades within a major.minor are stable point
upgrades per the OE-Core stable release policy (ref-manual, "Stable Point
Release Upgrades"). There is no written policy document, so qualification
rests on that branch structure and the release contents below.

  https://docs.yoctoproject.org/dev/ref-manual/release-process.html#stable-point-release-upgrades
  https://github.com/lttng/lttng-ust/tree/stable-2.15

Upstream keeps a ChangeLog with a per-release entry list, and every entry
for the one point release in the current series is labelled a fix. 2.15.1
(May 22 2026) covers a negative error code on incorrect message size, a
shmp() return value checked before dereference, an underflow warning in
zero_file, uninitialised LTTNG_UST_LFILE and sigevent structs, close_range
inefficiency and excessive fd-tracker memory use, and a NULL check in
ustctl. The one non-fix entry changes a likely to unlikely branch hint.

Only one point release exists in the 2.15 series so far, so this also
rests on the 2.13 series' record, which ran to ten.

Already tracked this way on the OE stable branches, counting only bumps
since each branch forked: kirkstone took 2.13.5 -> 2.13.6 and scarthgap
2.13.7 -> 2.13.8 -> 2.13.10. wrynose has taken none and sits at 2.14.0.

This probably needs to be updated in lockstep with other lttng*
recipes (modules, tools), and so they all must fit the criteria, or
you need to find out if one can be updated without the others.

I think they can be updated independently.

Currently in each version, they do not match their versions:
Scarthgap:
./meta/recipes-kernel/lttng/lttng-ust_2.13.10.bb
./meta/recipes-kernel/lttng/lttng-modules_2.13.12.bb
./meta/recipes-kernel/lttng/lttng-tools_2.13.13.bb

Wrynose:

./meta/recipes-kernel/lttng/lttng-ust_2.14.0.bb
./meta/recipes-kernel/lttng/lttng-modules_2.14.4.bb
./meta/recipes-kernel/lttng/lttng-tools_2.14.1.bb

master:
./meta/recipes-kernel/lttng/lttng-ust_2.15.1.bb
./meta/recipes-kernel/lttng/lttng-tools_2.15.1.bb
./meta/recipes-kernel/lttng/lttng-modules_2.15.2.bb

I have added already a patch for lttng-tools in the previous batch.
I'll check lttng-modules

Cheers,
Daniel

[PATCH 2/2] babeltrace2: inherit upstream-stable-release-point

[daniel.turull]

From: Daniel Turull <daniel.turull@ericsson.com>

babeltrace2 maintains a branch per minor series (stable-2.0, stable-2.1)
and keeps the older one alive: 2.0.7 and 2.1.2 were released the same day
in July 2025, with 2.1.1 already out since April. So upgrades within a
major.minor are stable point upgrades per the OE-Core stable release
policy (ref-manual, "Stable Point Release Upgrades"). There is no written
policy document, so qualification rests on that branch structure and the
release contents below.

  https://docs.yoctoproject.org/dev/ref-manual/release-process.html#stable-point-release-upgrades
  https://github.com/efficios/babeltrace/tree/stable-2.1

Upstream keeps a ChangeLog with a per-release entry list. Both point
releases in the current series are fixes, tests and documentation: 2.1.2
(Jul 22 2025) is 13 commits, and 2.1.1 (Apr 14 2025) 10.

Already tracked this way on the OE stable branches, counting only bumps
since each branch forked: kirkstone took 2.0.4 -> 2.0.5 and scarthgap
2.0.5 -> 2.0.6. wrynose has taken none and sits at 2.1.2.
