If this new scheme of adding dependencies is supposed to be used more
widely we need to start making it easy to add them. So add a new
self-contained header that projects can simply include without the need
to link against libsystemd itself. This will allow them to generate
`.notes.dlopen` sections:
```
> readelf -p .note.dlopen ./l2md
String dump of section '.note.dlopen':
[ a] |@FDO
[ 10] [{"feature":"manifest-json","description":"Manifest-based change detection via gzip and JSON parsing","priority":"suggested","soname":["libz.so.1","libsystemd.so.0"]}]
[ c2] |@FDO
[ c8] [{"feature":"manifest-http","description":"HTTP transport for lore.kernel.org manifest fetch","priority":"suggested","soname":["libcurl.so.4"]}]
```
The SYSTEMD_COLORS=true/1/yes no longer forced colors
when stdout was not a TTY (e.g. piped), because the COLOR_TRUE bypass
of the terminal_is_dumb() check was accidentally dropped.
Restore the old behavior by guarding the TTY check with
`m != COLOR_TRUE`, so an explicit boolean "true" value continues to
unconditionally force color output regardless of whether stdout is a TTY
or whether $NO_COLOR is set.
claude keeps failing by its subagents completing after it has already
written the review for large prs. It seems to run out of turns, tries
to get the subagents to post partial reviews but doesn't seem to stop
them.
Let's insist that it waits for background tasks to stop but let's also
increase the max turns a bit so it doesn't run out as quickly.
claude wants to use python to access the JSON context so let's allow
it. Since python3 basically allows you to reimplement every other tool,
let's just enable all tools except the web related ones but enable network
isolation so it can't try to exfiltrate anything via python.
Add a --grain-size= CLI option to override the default 4 KiB partition
alignment grain. Setting --grain-size=1M matches the alignment used by
fdisk/parted and fixes misaligned partitions after small fixed-size
partitions like the 16 KiB verity-sig partition.
Also fix context_place_partitions() to re-align the start offset after
each partition, not just once per free area. Without this, a small
partition would cause all subsequent partitions in the same free area
to start at an unaligned offset.
Relicense sd-dlopen.h from LGPL-2.1-or-later to MIT-0 so that
downstream projects can copy/paste the macros directly without
introducing a build dependency on the systemd headers.

Switch all internal callers from the private ELF_NOTE_DLOPEN() macro to
the new public SD_ELF_NOTE_DLOPEN() API from sd-dlopen.h, and remove
the now-redundant macro definitions from dlfcn-util.h.

Expose ELF note dlopen annotation macros as a public header-only API in
sd-dlopen.h. This allows any project to embed .note.dlopen metadata in
their ELF binaries by simply including the header - no runtime linkage
against libsystemd is required.
The header provides SD_ELF_NOTE_DLOPEN() and associated macros/constants
implementing the ELF dlopen metadata specification for declaring optional
shared library dependencies loaded via dlopen() at runtime.

Add %I (TID in initial PID namespace) to the core_pattern, so the
kernel passes the crashing thread's TID to systemd-coredump. Use it
to read the thread's comm name from /proc/<tid>/comm and log both as
new journal fields:
COREDUMP_TID= — TID of the crashing thread
COREDUMP_THREAD_NAME= — comm name of the crashing thread
These fields are also stored as xattrs on external coredump files
(user.coredump.tid, user.coredump.thread_name) and displayed by
coredumpctl info alongside the PID line.
For single-threaded processes the TID equals the PID and thread_name
equals comm; for multi-threaded programs with named worker threads
(pthread_setname_np / PR_SET_NAME) this identifies which thread
crashed without needing to open the coredump file itself.
The new fields are optional in the socket forwarding path, so older
systemd-coredump senders are handled gracefully.

These functions take so many return paramaters, and in many of our cases
we don't actually needt them. Hence introduce _full() flavours of the
funcs, and hide the params by default.
The labelling approach introduced in 6089075265
means contributors can now trigger the workflow on their own when the label
is added by a maintainer and they update the PR. Hence we need to allow all
users to access the claude code action. This is safe because we already gate
the workflow ourselves to only the contributors that we want to allow.
Additionally, the claude code job has no permissions anymore except read access
to the repository and can execute very limited tools, so this should be safe.
The name doesn't actually matter, it gets replaced with the name
of the file when not archiving. So stop passing a name and pass in
the filename as the name when downloading the artifact.
Rather than have claude fetch the context itself, let's fetch the
context for it in the setup job. This has the following advantages:
- We can reduce the permissions granted to the claude job
- claude has less opportunity to mess up trying to fetch the context
itself. Specifically, it keeps spawsning a background task to fetch
the PR branch which messes up the structured output at the end, causing
the review job to fail. By pre-fetching the context it won't have to
spawn the background task. Additionally, we limit the git commands it
can execute to local ones to ensure it doesn't try to fetch the PR branch.
Finally, we fetch the branch ourselves as pr-review so claude can look at it
to review the PR.
The Goodix GXTP5100 touchpad (HID bus 0x0018, vendor 0x27C6, product
0x01E9), found in the Lenovo ThinkBook 16 G7+ IAH and ThinkPad X9 15
Gen 1, has a kernel driver bug where ABS_PRESSURE (axis 24 / 0x18) is
reported with min=0, max=0.
This invalid axis range causes libinput to reject the device with:
"kernel bug: ABS_PRESSURE has min == max (both 0)"
The touchpad hardware itself is functional and reports valid ranges for
all other axes:
ABS_X: min=0, max=4149, resolution=31
ABS_Y: min=0, max=2147, resolution=27
ABS_MT_POSITION_X/Y: valid ranges
Root cause: the kernel hid-multitouch driver applies a "GT7868Q report
descriptor fixup" to this device (the HID descriptor is malformed and
fails hid-generic probe with EINVAL). The fixup corrects most axes but
leaves ABS_PRESSURE with an invalid 0:0 range.
This hwdb entry overrides ABS_PRESSURE to a valid 0:255 range, allowing
libinput to accept and initialize the device.
Kernel version: 6.17.0-19-generic
Device path: /sys/bus/hid/drivers/hid-multitouch/0018:27C6:01E9.0001
- If a pr is labeled with claude-review, review it immediately
- If a pr labeled with claude-review is updated, review it regardless
of the author
- If a pr is opened by a maintainer, review it and add the claude-review
label. If the claude-review label is later removed, the pr won't be
auto-reviewed anymore.
Bash(gh:api *) wasn't actually working. Turns out the colon syntax
is deprecated and unnecessary. Let's stop using it which also fixes
the bug so that gh api calls are allowed now.
Claude now identifies which existing review comment threads should be
resolved (because the issue was addressed or someone disagreed) and
returns their REST API IDs in a new `resolve` array in the structured
output. The post job uses GraphQL to map comment IDs to threads and
resolve them.
Also switches all GitHub data fetching from MCP tools to `gh api` calls,
since the MCP tool strips comment IDs during its GraphQL-to-minimal
conversion and cannot be used for thread resolution.
The thread resolution GraphQL pagination is wrapped in a try/catch so
that a failure to fetch threads degrades gracefully instead of aborting
the entire post job. Unmatched comment IDs are logged for debuggability.
Adds explicit instructions to complete all data fetching before starting
review and to cancel background tasks before returning structured output,
working around a claude-code-action issue where a late-completing
background task triggers a new conversation turn that overwrites the
structured JSON result.

Switch claude-review from reviewing the entire PR diff at once to
reviewing each commit individually via subagents. Each commit review
subagent receives the PR context, preceding commit diffs, and its own
commit diff, then returns comments tagged with the commit SHA. This
ensures review comments are attached to the correct commit via the
GitHub API rather than all pointing at HEAD.
Also add Bash(gh:*) to allowed tools so subagents can fetch per-commit
diffs via `gh api` without needing local git objects, and remove CI
analysis (needs to be delayed until CI finishes to be useful).

Address feedback from facebook/bpfilter#472:
- Fix setFailed error message counting file-level comments (without
line numbers) that are intentionally skipped, use inlineComments.length
instead of comments.length
- Fix double severity prefix in inline comments: the prompt told Claude
to prefix body with **must-fix**/etc but the post job also prepended
"Claude: ", producing "Claude: **must-fix**: ...". Now the prompt says
not to prefix and the post job adds "Claude **severity**: " using the
structured severity field
- Move error tracking instructions to a top-level section after all phases
so they apply to all runs, not just the first run
- Clarify that line is optional: use "should be" instead of "must be"
and document that omitting line still surfaces the comment in the
tracking comment summary
- Distinguish cancelled vs failed in tracking comment message
- Add side: "RIGHT" and subject_type: "line" to createReviewComment
per GitHub API recommendations
- Downgrade partial inline comment posting failures to warnings; only
fail the job when no comments at all could be posted

Use Coccinelle's "depends on" directive to exclude files from certain
transformations. This should make them a bit simpler and possibly
faster, since we don't have to shell out to Python.
Unfortunately, this works only for file/directory exclusions. For
function and other more complex exclusions we still need to use Python,
at least for now.
Also, completely drop the file exclusion for man/ in the xsprintf
transformation, since we filter out everything under man/ before we even
run Coccinelle (in run-coccinelle.sh).
