On some devices we see a weird in which /metadata/apex will have a wrong
selinux label. This will effectively prevent such devices from getting
any apex updates. Since we haven't figured out a root cause for this
bug, it's safer to explicitly call restorecon on /metadata/apex to make
sure it's correct.
This change shouldn't affect a normal boot flow, since /metadata/apex
will already have a correct label and restorecon_recursive will be a
no-op.
Test: rm -Rf /metadata/apex && \
mkdir /metadata/apex &&
mkdir /metadata/apex/sessions

(cherry picked from commit cf7b6bad55)
1) Add fuzzer for SerializedLogBuffer
2) Enable fuzzing on host
3) Read logs after writing them
4) Silence log tags error on host
Test: run these fuzzers

Logd never deletes SerializedLogBuffer, so it seemed reasonable to
detach the deleter thread, however unit tests and fuzzers do delete
SerializedLogBuffer, so we must safely join the deleter thread in the
destructor.
This simplifies the deleter thread code and ensures that only one
deleter thread will be running at a time.
Test: fuzzing works

Fix a bug that was causing cap_set_flag() fail and logd to exit.
Bug: 159588327
Test: caps are set correctly and logd functions with both, one of, or
none of klogd and auditd enabled.

Previously, colors were specified from the 216 additional colors, which
typically specify an exact RGB color value. Instead, use escape codes
for standard colors (default foreground, red, green, yellow, etc.),
which are commonly adjusted by terminal emulators user preferences.

If the flashed boot image is smaller than the block device, the AVB
footer will not be at the end of the partition. Although images are
normally created to match the partition size the GKI boot.img must work
on all devices, and the size of the boot partition will vary.
Copy the AVB footer to the end of the partition before flashing, if it
is not there already.

In order of severity:
1) Add a CHECK() that a pointer is not nullptr, where the analyzer
believes this is possible.
2) Add `final` appropriately to functions called from constructors.
3) Add missing cloexec flags.
4) Add missing `noexcept` and other subtle performance warnings

d3ecc66b9c "liblog: support extended logger_entry headers" removed
the logger_entry::msg variable and instead uses hdr_size as an offset
from logger_entry to where the message starts in parent log_msg
buffer.
In pmsg, hdr_size is not recorded and therefore uninitialized when it
was referenced, causing corruption when reading last logcat. This
change uses sizeof(log_msg->entry) instead.

As the EXT4_MAX_BLOCK_SIZE defined as 65536 which reached maxium value
of unsigned int. The superblock value maybe larger than 65536. This is
found by the Integer Overflow Sanitizer.

SnapshotUpdateTest uses a relatively small super partition, which
requires a small alignment and 0 alignment offset to work. For the
purpose of this test, hardcode the alignment and offset.
This test isn't about testing liblp or libdm.

Having mounted apexes with loop back devices backing files on /data
partition will prevent clean unmount of it. Unmounting them and tearing
down loop devices should minimize the risk of that.
Note that it won't fix the issue completely, as there are a few (~2-3)
processes that keep restarting even after SIGKILL is sent. Which means
that they can still hold references to apexes on /data partition. But
in practice probability of this is quite low.
Test: adb reboot
Test: put tzdata apex in /data/apex/active && adb reboot
