This PR reverts #4302 and part of #7568, as the call to GetEventLog
isn't necessary to get the logs from the OS runtime.
This has already been reverted in shim, see:
fd7c3bd920
The reasoning for the change that added this is wrong, explained below:
> According to TCG EFI Protocol Specification for TPM 2.0 family,
> all events generated after the invocation of EFI_TCG2_GET_EVENT_LOG
> shall be stored in an instance of an EFI_CONFIGURATION_TABLE aka
> EFI TCG 2.0 final events table.
This is correct and a valid reading of the TCG spec.
> Hence, it is necessary to trigger the internal switch through calling
> get_event_log() in order to allow to retrieve the logs from OS runtime.
However, this reasoning is incorrect. The "EFI TCG 2.0 final events
table" exists to allow the OS Runtime to get TCG events created during
or after the call to ExitBootServices. If systemd-boot didn't call
trigger_tcg2_final_events_table(), the call to HashLogExtendEvent will
write the event to the normal events table (i.e. the same place the
PCR 0 - 7 related events are written). Then the OS can obtain these
systemd-boot events in the same way it obtains normal events, via a
call to GetEventLog().
Tested on amd64 w/ TPM2 using the newest Linux kernel patches that
get the TPM2 formatted log:
https://www.lkml.org/lkml/2019/5/20/1590
I confirmed that this change still lets the OS runtime obtain the log
entries created by systemd-boot.

This does the following:
- rename enum udev_builtin_cmd -> UdevBuiltinCmd
- rename struct udev_builtin -> UdevBuiltin
- move type definitions to udev-rules.h
- move prototypes of functions defined in udev-rules.c to udev-rules.h
- drop to use strbuf
- propagate critical errors in applying rules,
- drop limitation for number of tokens per line.
We store the affinity mask in the native endian. However, over D-Bus we
must transfer the mask in little endian byte order.
This is the second part of c367f996f5.
If the machine was suddenly shutted down (hard reboot for example) while
processing core dump, temp files created manually (not with a O_TEMPFILE flag)
stay in the system. After reboot systemd-coredump treat them as usual files, so
they wouldn't be rotated and shall pollute the filesystem.
Solution is to simply add those temp files to systemd-tmpfiles configs.
Originally, `systemctl cat` would match only active units, for example:
$ systemctl cat sshd.service
would cat the sshd.service unit file even if the service was inactive.
However:
$ systemctl cat ssh*
would show it only if it was active.
Let's unify the behavior and cat all unit files regardless of a state,
if no state was given explicitly to filter.
This reverts commit 8688c29b5a, but leaves the
reproducer. Structured assignment should be enough to fully initialize the
variable and new0 is not necessary.
Should finally fix oss-fuzz-14688.
8688c29b5a wasn't enough.
The buffer retrieved from memstream has the size that the same as the written
data. When we write do write(f, s, strlen(s)), then no terminating NUL is written,
and the buffer is not (necessarilly) a proper C string.
