Recently, the maps for an elf in memory might show up looking like:
f0000-f1000 0 r-- /system/lib/libc.so
f1000-f2000 0 ---
f2000-f3000 1000 r-x /system/lib/libc.so
f3000-f4000 2000 rw- /system/lib/libc.so
The problem is that there is logic in the code that assumed that the
map before the execute map must be the read-only map. In the case
above, this is not true. Add a new prev_real_map that will point
to the previous map that is not one of these empty maps.
This will fix the backtraces that look like this:
#00 pc 0000000000050d58 /apex/com.android.runtime/lib64/bionic/libc.so!libc.so (offset 0x50000) (syscall+24) (BuildId: 5252408bf30e395d49ee270b54c77ca4)
To get rid of the !libc.so and the offset value, which is not correct.
Added new unit tests to verify this.
Added new offline test which an empty map between read-only and execute
map. Before this change, the backtraces had lines like
libc.so!libc.so (offset XXX) would be present.

It previously had 0755 permission bits
With such permissive bits, an unauthorized app can access a file using
the /mnt/pass_through path for instance even if access via /storage
would have been restricted.
It is now 0700
TODO: Change ACL for /mnt/user from 0755 to 0700 in vold only when
FUSE flag is on. Changing it with FUSE off breaks accessing /sdcard
because /sdcard is eventually a symlink to /mnt/user/0/primary

Incidentd needs to access /data/misc/logd to get persisted logs for
debugging purposes. Relax permissions on /data/misc/logd to allow
group (log) to access the dir and read its files. Effectively change
to:
drwxr-x--- logd log /data/misc/logd
-rw-r----- logd log /data/misc/logd/logcat*
Since this dir stores the past output of logcat, anyone that can run
logcat can be granted access to this dir. Access to this dir is further
guarded by SELinux. So it is safe.

It now returns Ok() if successful, NeedsReboot() if merge
it should be checked again after reboot, and Error() for
other errors.
This wraps UpdateState to help clients interpret the UpdateState value.
Also separate SnapshotManager::Return from FiemapStatus since they are
for different libraries and have (potentially) different set of error codes.

See the previous commit moving SetLogger and SetAborter to liblog for
motivation.
This creates more harmony between the two mechanisms in libbase and
liblog for checking loggability.
Currently:
1) libbase filters all messages based on its minimum log priority. For
example, if minimum log priority in libbase remained at its
default, but a tag was specifically opted into DEBUG logs via
log.tag.<tag>, libbase would not print this log.
2) liblog ignores libbase's minimum log priority. For example if a
process called SetMinimumLogPriority(WARNING) but used a library
that logged via liblog's ALOGI macro, that log would still be
printed even though the process intends on filtering out those INFO
messages.
With this change:
1) If both a minimum log priority and a priority through log.tag.<tag>
are set, then the lower of the two values is used.
2) If only one or the other is set, then that value is used. This
fixes the two issues described above.
3) If neither of these values are set, then the default of using INFO
is unchanged.

libbase is copied into each APEX module which requires it, meaning
that there may be multiple instances of libbase running within a
single process with their own copy of libbase's globals. This means
that SetLogger() and SetAborter() will only impact logs from the
instance of libbase that calls it. This change moves this state to
liblog, since it will only ever have one instance in a single
process.
One major side-effect here is that now both ALOGE style and LOG(...)
style logs will be handled through the same logger function. For
example, a logger specified through libbase's SetLogger() will now see
logs sent to liblog through ALOGE(). This is intended behavior.
A second side-effect is that libbase's stderr logger is used for all
host logging now. It's simply a better logging default than the
fake_log_device logger in liblog currently and makes ALOGE and
LOG(...) logs on host follow the same format.
