This does what we do for system extension also for configuration
extension.
This is complicated by the fact that we previously looked for
<uki-binary>.d/*.raw for system extensions. We want to measure sysexts
and confexts to different PCRs (13 vs. 12) hence we must distinguish
them, but *.raw would match both kinds.
This commit solves this via the following mechanism: we'll load confexts
from *.confext.raw and sysexts from *.raw but will then enclude
*.confext.raw from the latter. This preserves compatibility but allows
us to somewhat reasonable distinguish both types of images.
The documentation is updated not going into this detail though, and
instead now claims that sysexts shall be *.sysext.raw and confexts
*.confext.raw even though we actually are more lenient than this. This
is simply to push people towards using the longer, more descriptive
suffixes.
I added an XML comment (<!-- … -->) about this to the docs, so that
whenever somebody notices the difference between code and docs
understands why and leaves it that way.
Currently, link_queue_request_safe(), which is a wrapper of
request_new(), is called with a free function at
- link_request_stacked_netdev() at netdev/netdev.c,
- link_request_address() at networkd-address.c,
- link_request_nexthop() at networkd-nexthop.c,
- link_request_neighbor() at networkd-networkd.c.
For the netdev case, the reference counter of the passed object is increased
only when the function returns 1. So, on failure (with -ENOMEM)
previously we unexpectedly dropped the reference of the NetDev object.
Similarly, for Address and friends, the ownership of the object is moved to the
Request object only when the function returns 1. And on failure, previously
the object was freed twice.
Also, netdev_queue_request(), which is another wrapper of request_new()
potentially leaks memory when the same NetDev object is queued twice.
Fortunately, that should not happen as the function is called only once
per object.
This fixes the above issue, and now the ownership or the reference
counter of the object is changed only when it is succeeded with 1.
Then, replace address_remove_and_drop() with it.
If an address is requested, and the request is already called,
we may not received its reply and notification from the kernel, and
the corresponding address object may not be remmbered. Even in such
case, we need to remove the address, otherwise the address will come
later after the function called.
Otherwise, udev workers cannot detect slow programs invoked by
IMPORT{program}=, PROGRAM=, or RUN=, and whole worker process may be
killed.
Fixes#30436.

Also, calculate the timeout for warning based on the remaining time for
the timeout of the event, rather than the timeout itself.
Currently, udev manager kills the worker if the timeout exceeds. So,
this does not change anything except for the timing of the warning.
Just refactoring and preparation for later commits.
We simply don't carry any userspace support for TPM1.2 in our tree, and
we shouldn't given it's too weak by today's standards. Hence, if we
check if we are booted in UKI measured boot mode, don't just check if we
are booted in EFI, but also check that we have a TPM2 chip (as opposed
to none or only a TPM1.2 chip).
This is an alternative to #30652 but more comprehensive (and simpler),
since it covers all invocations of efi_measured_uki().
Fixes: #30650
Replaces: #30652
This makes the folloing:
- Each Directory object now has a reference to sd-journal.
- Hence, directory_free(), which is renamed from remove_directory(), can
be called without sd-journal as an argument.
- Introduces hash ops for Directory, so the finalization becomes
slightly simpler.
- Allocate hashmaps that store Directory objects when necessary.
- Split out add_directory_impl().
No functional changes, just refactoring.
udevadm lock did not propagate the return code from the child process
because all positive values were treated as success.
v2:
Now 'udevadm test-builtin' ignores all positive return values from the
builtin commands. Otherwise, as the hwdb builtin returns an positive value
when a matching entry found, 'udevadm test-builtin hwdb' will fail.
v3:
Initialize partition table before calling 'sfdisk --delete'.

The similar check already exists in schedule_post_change().
The function is currently called at two places.
- journal_file_open() in sd-journal:
In this case, if the timer is not set up, then journal_file_post_change()
will be called at the end of journal_file_append_entry(). So, the necessary
task will be done sequentially when an journal entry is stored to the opened
journal file. That is desired when the function is called at outside of the
event loop.
- server_open_journal() in journald:
This is not called after we exit the event loop.
So, we can safely do nothing in the function if the event loop is being
finished or already finished.
Fixes#30644.
Adds some new dns record types. Also, some types were inserted into the
middle of the enum — this corrects an error where the enum constants for
some of the record types previously held an incorrect value.
