<!-- Use this template to notify community kernel maintainers that their

Hi, as per our
[device categorization requirements for the community category](https://docs.postmarketos.org/pmaports/main/device-categorization.html#community),
devices in the community category may not use a kernel version older than 6
months.
As of today (dd-mm-yyyy), the following kernels do not meet this requirement:
* kernel-pkgname: kernel-pkgver, version-release-date (maintainers: @ ...)
This issue is an attempt to notify you (the maintainers) of the situation so
that you can update the packages. As per the rules, you have two weeks to
update the packages or reply with a request for more time, up to one month
of time from the moment this issue is opened. If that time passes and the
devices still no longer meet the requirements, they will be moved to testing.

Name this issue "vYY.MM Infrastructure".
-->
Person in charge of the release (doesn't have to do all the work, but has to
push it forward):
<!-- Put your usename here and assign yourself to this issue -->
### Preparation
- [ ] Create the gitlab milestone for the release
- [ ] Add this infrastructure issue to the milestone
- [ ] Update the
[timeline](https://docs.postmarketos.org/policies-and-processes/development/releases/current-timeline.html)
for the next release
### Pre-Build phase
This phase is to get some extra time for building packages. The branch will be rebased once in the branch phase.
#### Requirements
- [ ] Alpine's main repository must be built and published
- [ ] Alpine's community repository must be built and published
#### pmbootstrap: adjust config
- [ ] Update `pmb/config/__init__.py:apk_tools_min_version`. This should be a
trivial change, push it directly to main.
- [ ] (can be done later, at start of test phase) make a new [pmbootstrap
release](https://wiki.postmarketos.org/wiki/Pmbootstrap_release) <small>bpo
uses the main branch, so it will be fine without a release, however users
will want to try out the new release and may not run main.</small>
#### pmaports: create branch and initial changes
- [ ] `git checkout -b vYY.MM main`
- [ ] Create a `=== Branch vYY.MM from main ===` commit
- Remove channels.cfg (should only be in main)
- Change `channel=edge` to `channel=vYY.MM` in pmaports.cfg
- Change `supported_arches` to `x86_64,aarch64,armv7` in pmaports.cfg
- Disable x86, armhf, riscv64 in .ci/build-jobs.yaml.j2 on the release branch
and delete `.ci/build-*` scripts for these arches
- [ ] `git push`
- [ ] '''protect the new release branch in gitlab''', so nobody can force-push to it
#### pmaports: update main branch
- [ ] `git checkout main`
- [ ] Add the new branch to
[channels.cfg](https://wiki.postmarketos.org/wiki/Channels.cfg_reference),
[like this](https://gitlab.postmarketos.org/postmarketOS/pmaports/-/commit/c43571ceaf9b8155519bc9fb760bdeccd96e7e9c)
- [ ] `git push`
#### pmaports: update os-release / remove packages / aportgen
- [ ] `git checkout vYY.MM`
- [ ] Update `postmarketos-base`:
- [ ] Set version info for `/usr/lib/os-release` in
`main/postmarketos-base/rootfs-usr-lib-os-release`
(`PRETTY_NAME="postmarketOS vYY.MM"`, `VERSION_ID="vYY.MM"`,
`VERSION="vYY.MM"`)
- `pmbootstrap pkgrel_bump postmarketos-base`
- `pmbootstrap config mirrors.pmaports none`
- `pmbootstrap config mirrors.systemd none`
- `pmbootstrap checksum postmarketos-base`
- `git commit`
- [ ] Remove packages:
- `cross/*-armhf` and other unsupported arches in cross dir (keep `gcc-x86` and `musl-dev-x86`, `systemd-boot-x86`)
- `main/postmarketos-ui-asteroid` (no smartwatches are useful on stable branches at the moment)
- `gcc4*` and `gcc6*` from main and cross dirs
- `device/downstream`, `device/archived`
- [ ] Run `pmbootstrap aportgen` for packages in cross
- [ ] `git push`
#### bpo: adjust config
- [ ] Add the branch to the
[build.postmarketos.org](https://gitlab.postmarketos.org/postmarketOS/build.postmarketos.org)
config in `bpo/config/const/__init__.py:branches` below `branches["main"]`,
so it builds with lower priority than main until it's released. Set `ignore_errors` to `True`.
- [ ] Make a merge request, wait until CI passes, merge it (or if you can directly push to main that's also fine since it's a trivial change)
- [ ] Roll it out/ask somebody who can do that
- [ ] Restart bpo, it will start building `x86_64` packages
#### bootstrap of binary packages
- [ ] Fix failing `x86_64` packages (Remember: patches need to go through edge
first, then get backported to the stable branch!)
- Try to get build fixes merged to edge quickly, ask for reviews in
#postmarketos-devel, and consider merging trivial fixes right after they
pass CI.
- Devices in testing and archived categories that don't build: consider
trying to fix them, or just delete them from the branch
- [ ] Wait until all packages for `x86_64` are built and published
- [ ] Fix up ARM packages too
- [ ] Wait until all packages for ARM are built and published
#### Wallpaper poll
- [ ] Team meeting: make a short list of 4 wallpapers from [the
pool](https://gitlab.postmarketos.org/postmarketOS/artwork/-/tree/main/wallpapers/2024)
- [ ] Make a poll on the wallpapers on mastodon
([example](https://fosstodon.org/@postmarketOS/113624366198561582))
- Make sure to thank the wallpaper authors (usually dikasp) for the amazing
work on the wallpapers
- Put the names of the wallpapers on top of the wallpapers for easier voting
and as alt text
- Create a comment with poll options
#### Adjust CI
- [ ] Make sure pmaports.git CI runs through on the new branch (run
`pmbootstrap ci`). Examples of why it might fail:
- One postmarketos-ui package has a package from alpine testing in their
_pmb_recommends.
- Remove the UI if it is not used much (can bring it back on demand) or
fork the package to the new branch
- Consider fixing it in edge, so we don't run into this with the next
release
- [ ] Adjust
[upstream-compat](https://gitlab.postmarketos.org/postmarketOS/continuous-testing/upstream-compat)
to run on the new release and make sure it passes
([example](https://gitlab.postmarketos.org/postmarketOS/continuous-testing/upstream-compat/-/merge_requests/10))
#### Adjust release upgrade script
- [ ] Add the new release to `upgrade.sh` in [postmarketos-release-upgrade](https://gitlab.postmarketos.org/postmarketOS/postmarketos-release-upgrade/)
- [ ] Bump `SCRIPT_VERSION`, tag a new release
- [ ] Package it for edge (make MR), backport it to the new release, but NOT to
the old release yet (otherwise users may upgrade by accident, without
realizing that the new version is not out yet!)
- [ ] Adjust CI of postmarketos-release-upgrade to test the new release too
(`git grep` for the previous release to see what needs to be adjusted)
### Update the wallpaper
- [ ] Set the wallpaper that won in the poll in edge, backport this change to
the stable release branch
### Branch phase
#### Rebase on main
- [ ] `git checkout vYY.MM`
- [ ] `git rebase -i origin/main`
- [ ] Temporarily enable force-push for the `vYY.MM` branch
- [ ] `git push --force-with-lease`
- [ ] Disable force-push for the `vYY.MM` branch again
#### Update BPO config
- [ ] Update bpo's images config to build images for the new branch for all
devices in community and main, except for:
- qemu-*
- [ ] bpo: configure the new branch to be not WIP anymore
- [ ] Roll-out bpo changes
#### pmb release done?
- [ ] Ensure that a pmbootstrap release been made with the apk-tools min
version change
### Test phase
- [ ] Create an issue in pmaports with a checklist of devices and UIs in main
and community (see previous issue for reference)
- Tag the testers of each device and UI
- Ask to verify that the images work as expected
- Release upgrade script: when coming from the previous release, grab it from
main: `wget https://gitlab.postmarketos.org/postmarketOS/postmarketos-release-upgrade/-/raw/main/upgrade.sh`
- [ ] Announce the new phase in the testing chat - and ask them to do the
testing within one week, as in the timeline.
- Prioritize merging fixes from maintainers (they do the heavy lifting in the
testing and fixing phase, see timetable)
- Make sure to properly cherry pick fixes from MRs to edge, if they are
intended for the upcoming release
- [ ] Add new version to the pmaports gitlab issue template (.gitlab dir)
### Release phase
- [ ] Did a reasonable amount of devices get tested? (we may consider dropping
devices that were not tested)
- [ ] Make sure all fixes are in
- [ ] Make sure new images are generated *with* the fixes (unless it's a fix
for something that doesn't impact the experience much and is fine to get with
the first update after installing)
- [ ] Announce the new phase in the testing chat, together with the planned
date of blog post release (and testing)
#### Write blog post
- [ ] Write a blog post for the new release in `postmarketos.org.git`:
- Look at the previous release blog post and try to make the new one
consistent with it
- Highlight major changes since the last release
(see the release notes issue)
- Mention new devices, and total list of devices
- Count devices that have their own wiki page as separate device
- E.g. OnePlus 6, 6T are two devices (two wiki pages), but variants of
"Samsung Galaxy A3 (2015)" are one device (one wiki page)
- Don't count/list devices for which we don't build images (e.g.
qemu-amd64)
- Adjust the homepage config to point to the new release in the downloads
page
- update `config/download.py`:
- `latest_release`
- update devices and categories. only list the ones where we actually build images.
- Add some cool photos
- Submit the blog post as MR to postmarketos.org.git.
- Let the blog post MR close the current release notes issue.
- Ask for reviews.
#### Release!
- [ ] Backport the new postmarketos-release-upgrade version that allows
upgrading to the new release, to the previous release (don't do this before
the release is tested and ready! During the testing phase, we can use
postmarketos-release-upgrade from main directly: `wget
https://gitlab.postmarketos.org/postmarketOS/postmarketos-release-upgrade/-/raw/main/upgrade.sh`)
- [ ] Add the branch to pkgs.postmarketos.org
- [ ] Merge the blog post
- [ ] Edit channels.cfg, change descriptions:
- New release: "Latest release / Recommended for best stability"
- Old release: "Old release (supported until YYYY-MM-DD)" (one month from date of the release)
- [ ] Create a milestone for the next release
- [ ] Create an issue for the next release notes and attach it to that milestone
- [ ] Update the [Releases](https://docs.postmarketos.org/pmaports/main/releases.html) page
- Move the new release to the list of active releases, link to the blog post
- Update the announcement and title for the release
- Add a new upcoming release below
- [ ] Update [Template:Latest stable release](https://wiki.postmarketos.org/wiki/Template:Latest_stable_release) on the wiki with the new version
- [ ] Update "Default description template for issues" in pmaports (.gitlab dir)
- In "On what postmarketOS version did you encounter the issue?", change:
- previous release: add " (supported until YYYY-MM-DD)"
- add the new release
- [ ] Put a reminder in recurring-admin-tasks to drop support for the old release

Provide struct_sock_fprog_sz on Linux, rather than on Linux+glibc.
With `#include <linux/filter.h>` `struct sock_fprog` is available when
linux headers are available. It seems that glibc is just including that header
as an implementation detail, while musl does not.

From 824eae920f0f64dd7687c969a2436b129161fdc9 Mon Sep 17 00:00:00 2001
From: Jinyang He <hejinyang@loongson.cn>
Date: Wed, 29 Oct 2025 16:07:35 +0800
Subject: [PATCH] LoongArch: Only allow valid binary op when optimize
conditional move
It is wrong that optimize from `if (cond) dest op= 1 << shift` to
`dest op= (cond ? 1 : 0) << shift` when `dest op 0 != dest`.
Like `and`, `mul` or `div`.
And in this optimization `mul` and `div` is optimized to shift.
gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_expand_conditional_move): Only allow valid binary
op when optimize conditional move.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/conditional-move-opt-1.c: Remove mul.
* gcc.target/loongarch/conditional-move-opt-2.c: Remove and.
* gcc.target/loongarch/conditional-move-opt-3.c: New test.

Subject: [PATCH] tree-object-size.cc: Fix assert constant offset in
check_for_plus_in_loops [PR122012]
After commit 51b85dfeb19652bf3e0aaec08828ba7cee1e641c, when the
pointer offset is a variable in the loop, the object size of the
pointer may also need to be reexamined.
Which make gcc_assert in the check_for_plus_in_loops failed.
gcc/ChangeLog:
PR tree-optimization/122012
* tree-object-size.cc (check_for_plus_in_loops): Skip check
for the variable offset
gcc/testsuite/ChangeLog:
PR tree-optimization/122012
* gcc.dg/torture/pr122012.c: New test.

Subject: [PATCH] gcc: poison-system-directories
Add /sw/include and /opt/include based on the original
zecke-no-host-includes.patch patch. The original patch checked for
/usr/include, /sw/include and /opt/include and then triggered a failure and
aborted.
Instead, we add the two missing items to the current scan. If the user
wants this to be a failure, they can add "-Werror=poison-system-directories".

Previously, we also used to turn on -z relro here, but we now build
binutils with --enable-relro, which is functionally equivalent.
Binutils does not appear to have a similar option for enabling -z
now by default.

Subject: [PATCH] Ensure that msgfmt doesn't encounter problems during gcc
bootstrapping.
Solves error messages like the following:
msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
The libgcc_s.so used during build doesn't satisfy the needs of the
libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
is used as a stand-alone application here, and what library it uses
behind the scenes is of no concern to the gcc build process.
Therefore, simply invoking it "as usual", i.e. without any special
library path, will make it work as expected here.

Subject: [PATCH] Alpine musl package provides libssp_nonshared.a. We link to
it unconditionally, as otherwise we get link failures if some objects are
-fstack-protector built and final link happens with -fno-stack-protector.
This seems to be the common case when bootstrapping gcc, the piepatches do
not seem to fully fix the crosstoolchain and bootstrap sequence wrt.
stack-protector flag usage.

Subject: [PATCH] riscv: disable multilib support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From the musl wiki [1]:
musl does not support sharing an include directory between archs
[…], and thus is not compatible with GCC-style multilib. It is
recommended that distributions build GCC with multilib disabled,
and use library directories named lib, not lib64 or lib32.
For this reason, we patch existing GCC configuration files (gcc/config)
to pin MULTILIB_OSDIRNAMES to lib, there is also a corresponding GCC
upstream bug about this issue [2]. Avoiding the use of lib64 and lib32
directories is a bit more difficult on the RISC-V architecture. This is
due to the fact that the default RISC-V configuration does not only use
the lib64 and lib32 directories but also subdirectories within these
directories for different RISC-V ABIs (e.g. lp64d, lp64, …) [3].
This patch aligns the RISC-V configuration with other architectures by
pinning MULTILIB_OSDIRNAMES to lib for rv64gc (our default RISC-V
-march). Furthermore, this patch removes the ABI-specific startfile
prefix spec. Since both of these impact the default LIBRARY_PATH [4]
this patch thereby aligns the default RISC-V LIBRARY_PATH with that from
other Alpine architectures and thereby fixes #13369 [5].
Incidentally, this also fixes gccgo on riscv64, as without this patch
gccgo is otherwise not able to find the *.gox files for the Go standard
library.

Subject: [PATCH] configure: fix detection of atomic builtins in libatomic
configure script
Alpine's --enable-autolink-libatomic (which is enabled for riscv64 by
default) causes the libatomic configure script to incorrectly detect
which builtins are available on riscv64. This then causes incorrect code
generation for libatomic since it assumes compiler builtins to be
available which are not actually available on riscv64.
This commit fixes this issue by disabling linking of libatomic configure
test code entirely, thereby preventing linking against libatomic.
See:
* https://gitlab.alpinelinux.org/alpine/aports/-/issues/12948
* https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101996#c6

+# The libatomic configure script performs several checks to determine
+# whether builtins for atomic operations are available. When compiling
+# with --enable-autolink-libatomic the test code compiled by the
+# configure script is also linked against libatomic. This causes it
+# to think that builtins are available, even if there are not, since
+# the tested symbols are provided by libatomic.
+#
+# This is a hack to ensure that we don't link against libatomic by not

Subject: [PATCH] druntime: link against libucontext on all platforms
On musl-based Linux distributions, swapcontext etc. are not provided by
musl but instead by libucontext. Hence, we _always_ need to link against
an external library for these functions.

Subject: [PATCH] static PIE: ensure -static reaches the linker
on some targets, the logic for the compiler option -static seems not
to be processed when -pie is present. rather than playing
whack-a-mole, just ensure LD_PIE_SPEC specs always pass -static to ld
if either -static or -static-pie is present on the compiler driver
command line.
this may produce redundant -static arguments but it doesn't matter.

From 4c8cc9a8621b91f8aa83d8ca81f22b00a98d9fa9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] except: Don't use the cached value of the gcc_except_table
section for comdat functions [PR119507]
This has been broken since GCC started to put the comdat functions' gcc_except_table into their
own section; r0-118218-g3e6011cfebedfb. What would happen is after a non-comdat function is processed,
the cached value would always be used even for comdat function. Instead we should create a new
section for comdat functions.
OK? Bootstrapped and tested on x86_64-linux-gnu.
PR middle-end/119507
gcc/ChangeLog:
* except.cc (switch_to_exception_section): Don't use the cached section if
the current function is in comdat.
gcc/testsuite/ChangeLog:
* g++.dg/eh/pr119507.C: New test.

Provide struct_sock_fprog_sz on Linux, rather than on Linux+glibc.

Subject: [PATCH] LoongArch: Only allow valid binary op when optimize
conditional move
It is wrong that optimize from `if (cond) dest op= 1 << shift` to
`dest op= (cond ? 1 : 0) << shift` when `dest op 0 != dest`.
Like `and`, `mul` or `div`.
And in this optimization `mul` and `div` is optimized to shift.
gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_expand_conditional_move): Only allow valid binary
op when optimize conditional move.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/conditional-move-opt-1.c: Remove mul.
* gcc.target/loongarch/conditional-move-opt-2.c: Remove and.
* gcc.target/loongarch/conditional-move-opt-3.c: New test.

Subject: [PATCH] tree-object-size.cc: Fix assert constant offset in
check_for_plus_in_loops [PR122012]
After commit 51b85dfeb19652bf3e0aaec08828ba7cee1e641c, when the
pointer offset is a variable in the loop, the object size of the
pointer may also need to be reexamined.
Which make gcc_assert in the check_for_plus_in_loops failed.

Subject: [PATCH] gcc: poison-system-directories
Add /sw/include and /opt/include based on the original
zecke-no-host-includes.patch patch. The original patch checked for
/usr/include, /sw/include and /opt/include and then triggered a failure and
aborted.
Instead, we add the two missing items to the current scan. If the user
wants this to be a failure, they can add "-Werror=poison-system-directories".

Previously, we also used to turn on -z relro here, but we now build
binutils with --enable-relro, which is functionally equivalent.
Binutils does not appear to have a similar option for enabling -z

Subject: [PATCH] Ensure that msgfmt doesn't encounter problems during gcc
bootstrapping.
Solves error messages like the following:
msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
The libgcc_s.so used during build doesn't satisfy the needs of the
libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
is used as a stand-alone application here, and what library it uses
behind the scenes is of no concern to the gcc build process.
Therefore, simply invoking it "as usual", i.e. without any special
library path, will make it work as expected here.

Subject: [PATCH] Alpine musl package provides libssp_nonshared.a. We link to
it unconditionally, as otherwise we get link failures if some objects are
-fstack-protector built and final link happens with -fno-stack-protector.
This seems to be the common case when bootstrapping gcc, the piepatches do
not seem to fully fix the crosstoolchain and bootstrap sequence wrt.
stack-protector flag usage.
