`READY=1` is already correctly emitted when acquiring an update, but was
forgotten to be emitted when subsequently installing that update.
That meant that the state tracking code in `sysupdated` and hence
`updatectl` could not properly report the progress of the install
operation, and hence printed “Already up-to-date” after a successful
update installation, rather than “Done”.
Add a test to catch this in future.

Convert curl-util to the dlopen pattern used by other optional shared
libraries in libshared (libarchive, pcre2, idn, ...). Declare the curl
API entry points with DLSYM_PROTOTYPE, resolve them in a dlopen_curl()
helper, and call the sym_* wrappers from callers. curl_glue_new() now
loads the library on first use, so consumers going through CurlGlue
pick this up automatically; journal-upload and report-upload call
dlopen_curl() directly since they use curl without the glue layer.
With this in place curl-util can live in libshared itself, linked only
against libcurl's headers (via libcurl_cflags). The libcurlutil_static
convenience library and the libcurl link dependency on systemd-imdsd,
systemd-pull, systemd-journal-upload and systemd-report go away.
Also move the easy_setopt() helper macro next to the DLSYM declarations
so all consumers use a single sym-prefixed definition, and add a
dlopen_curl() check to test-dlopen-so.
The json-stream API previously exposed JsonStreamQueueItem and several
functions operating on it (json_stream_make_queue_item(),
json_stream_enqueue_item(), json_stream_queue_item_free(),
json_stream_queue_item_get_data()). These existed solely to support
sd-varlink's "defer-and-modify" pattern for streaming replies, where a
reply is held back so its "continues" field can be set before
transmission. This is a varlink protocol concern that should not leak
into the generic transport layer.
Similarly, the fd pushing API (json_stream_push_fd(),
json_stream_reset_pushed_fds()) and the pushed_fds state lived inside
JsonStream, even though fd-to-message association is a protocol-level
concern managed entirely by sd-varlink.
Rework the API so that:
- JsonStreamQueueItem and all its functions become static to
json-stream.c. The only output API is now json_stream_enqueue_full()
(accepting explicit fds) and the inline json_stream_enqueue() wrapper
for the common no-fds case.
- The pushed_fds state moves from JsonStream into sd_varlink, where
sd_varlink_push_fd() and sd_varlink_reset_fds() manage it directly.
- The deferred reply in sd-varlink changes from a JsonStreamQueueItem*
to a plain sd_json_variant* plus a separate previous_fds/n_previous_fds
pair, keeping the protocol-specific bookkeeping in sd-varlink where it
belongs.
- A new varlink_enqueue() helper wraps json_stream_enqueue_full() with
the varlink connection's pushed fds, transferring fd ownership to the
queue item on success.
qmp-client.c is fixed to use the new API as well.
The reworks the ESP/XBOOTLDR logic to pin the ESP/XBOOTLDR via an fd,
and return that as optional return parameter.
So far we only pinned the parent dir of the ESP/XBOOTLDR, which was
useful when verifying that ESP/XBOOTLDR is actually a mount point by
comparing mount ids. This however became obsolete with
a98a6eb95c. Hence, let's clean this up,
and pin the inode we really care about and return it.
Some flags don't reasonably apply to chase_and_unlinkat() (because we
open the parent inode of an inode to delete, which is always a dir),
hence let's catch these flags when misused.
(I ran into this, and it was very confusing to debug, hence let's make
it easier)
Newer tar started using openat2() via open_subdir() to address
CVE-2025-45582 [0]. Now, gnulib, that tar uses, provides the openat2()
syscall in two ways [1]:
1) If glibc doesn't provide openat2(), it provides its own version in
openat2.c, that tries to call openat2() syscall first, and if it
returns ENOSYS, it emulates the function in userspace.
2) If glibc provides openat2(), it uses that directly, without providing
any fallback on ENOSYS.
Quite recently our test suite started calling nspawn with
--suppress-sync=yes. This means that we call seccomp_suppress_sync(),
which eventually calls block_open_flag(), that blocks the openat2()
syscall completely and refuses it with ENOSYS as this syscall can't be
sensibly filtered (see the openat2()-relevant comments in
block_open_flag() and seccomp_restrict_sxid()). And when glibc provides
openat2(), there's no fallback, so the ENOSYS bubbles up to the user as:
TEST-25-IMPORT.sh[163]: + tar xzf /var/tmp/scratch.tar.gz
TEST-25-IMPORT.sh[163]: tar: ./adirectory/athirdfile: Cannot open: Function not implemented
TEST-25-IMPORT.sh[163]: tar: Exiting with failure status due to previous errors
Let's mitigate this by re-enabling sync for TEST-25-IMPORT, at least for
now.

Add "overlay", which is already mentioned further down below, to the
list of possible options.
Consistently use <literal> for possible values of systemd.volatile=,
rather than <param> or no special formatting.
Use yes/no rather than true/false as boolean since that is what's used
everywhere else and I'm already touching the lines anyway.
In nspawn.c's run_container() the child_netns_fd = receive_one_fd(...)
failure path logged 'r' instead of the negative errno returned in
child_netns_fd, so the actual error from receive_one_fd was being
overwritten by whatever 'r' happened to hold. The other receive_one_fd
call sites in the same function use the returned fd variable directly
(mntns_fd, etc.), so align this one.
In shared/nsresource.c's nsresource_add_cgroup() the cgroup_fd_idx =
sd_varlink_push_dup_fd(...) failure path logged userns_fd_idx, which
is the previous successful push's index, not the negative errno we
just got from pushing cgroup_fd. Log cgroup_fd_idx instead.
Both were flagged by static analysis (#41709) and match the immediately
preceding userns_fd-path pattern that was presumably copy-pasted.
Refs #41709.
If a journal file contains a truncated ZSTD frame (i.e. a frame with
Frame_Content_Size > 0, but with not enough data in Data_Block),
ZSTD_decompressStream() would return a non-zero, non-error value. This
would then skip the error path in the ZSTD_isError() branch and we'd hit
the following assert:
$ build-local/journalctl -o cat --file zstd-truncated.journal
Assertion 'output.pos >= prefix_len + 1' failed at src/basic/compress.c:1236, function decompress_startswith_zstd(). Aborting.
Aborted (core dumped) build-local/journalctl -o cat --file zstd-truncated.journal
Let's handle this situation gracefully and return EBADMSG instead.
Also, add another journalctl invocation to the corrupted-journals test
that goes through the sd_journal_get_data() -> decompress_startswith_zstd()
code path which, among other things, covers the issue when run on the
provided journal file.
vsnprintf() can, under some circumstances, return negative value, namely
during encoding errors when converting wchars to multi-byte characters.
This would then wreak havoc in the arithmetics we do following the
vsnprintf() call. However, since we never do any wchar shenanigans in
our code it should never happen.
Let's encode this assumption into the code as an assert(), similarly how
we already do this in other places (like strextendf_with_separator()).
The naming is consistent with strv_extend().
This also
- introduces tiny iovw_extend_iov() wrapper,
- refuse when the source and target points to the same object,
- check the final count before extending in iovw_extend_iovw().
This is similar to iovw_to_cstring(), but allows embedded NUL, as this
just concat multiple iovec, the result may not be a string.
Now, iovw_to_cstring() internally uses iovw_concat().
systemd-repart currently creates LUKS2 encrypted partitions using
libcryptsetup's default KDF (Argon2id), which requires ~1GB of memory
during key derivation. This is too much for memory-constrained
environments such as kdump with limited crashkernel memory, where
luksOpen fails due to insufficient memory.
Add an EncryptKDF= option to repart.d partition definitions that allows
selecting the KDF type. Supported values are:
- "argon2id" — Argon2id with libcryptsetup-benchmarked parameters
- "pbkdf2" — PBKDF2 with libcryptsetup-benchmarked parameters
- "minimal" — PBKDF2 with SHA-512, 1000 iterations, no benchmarking,
matching the existing cryptsetup_set_minimal_pbkdf() behaviour used
for TPM2-sealed keys
When not specified, the libcryptsetup default (argon2id) is used,
preserving existing behaviour.
The KDF type is applied via sym_crypt_set_pbkdf_type() after
sym_crypt_format() and before any keyslots are added.
Split out of #41543.
These don't make too much sense on their own, but they also don't really
hurt. They are preparation for #41543, but in order to make things
either to review I split these four commits out, since they are not
directly part of what the PR shall achieve
The NOTES section in os-release(5) contains an unusual formatting.
Switch function and ulink tags and remove a newline within ulink text to
keep the entry formatting in sync with others. Also, this preserves the
formatting within the text itself.

Not sure if it is an issue in valgrind or glibc, but at least there is
nothing we can do except for working around it.
