4d8f37edae Updated the policy file associated with riscv64
The generate.sh script can generate the file, but current policy file does not match it.
And the rules are not appropriate, like missing "sysinfo", causing the
debuggerd_test to fail in system model. So we match the policy to
what it should be.

Test: make debuggerd_test

926f753e20 Symbolic constants for older minijails
Inline definitions of a few constants that don't appear on Q/R devices,
so that this works for us in mainline modules that are loaded on those
older devices.

Test: boot on Q, watch logcat
Test: boot on R, watch logcat

b999b82eb7 Dump threads in tombstone fallback path.
When dumping a tombstone using the fallback path, only the main
thread was showing up. Modify the code to dump the threads using
a slightly different path for the tombstone generation code.

In addition, while looking at this code, two MTE variables were
not set in the tombstone fallback code. Added those variables
so MTE devices will work properly in this fallback path.

Modified the tombstone unit tests for seccomp to have
multiple threads and verify those threads show up in the tombstone.

Bug: 208933016

Test: Ran unit tests.
Test: Ran debuggerd <PID> on a privileged process and verified
Test: all threads dumped. Also verified that the tagged_addr_ctrl
Test: variable is present on the raven device.

32d3cdda22 libdebuggerd: fix process uptime.
I was here because we have a case where timeout(1) kills logcat, but
debuggerd alleges that the process that was killed had started less than
a second ago. I'm not sure this is the problem there, but I did notice
that far too many tombstones were claiming improbably short process
uptimes. It turns out that the code was measuring the *thread* uptime,
not the *process* uptime.

Also simplify the code a bit by switching to sysinfo(2) rather than
reading a file.

Test: manual, plus the existing unit test

6702256e0c Allow another prctl call.
A change was made so that pthread_create is calling
prctl(PR_PAC_RESET_KEYS, ...) on aarch64. It's possible that other
seccomp policies might need to change to allow this.

Test: CrasherTest.seccomp_backtrace passes on aarch64.

92317d82c9 libdebuggerd: add protobuf implementation.
This commit implements protobuf output for tombstones, along with a
translator that should emit bytewise identical output to the existing
tombstone dumping code, except for ancillary data from GWP-ASan and
Scudo, which haven't been implemented yet.

Test: setprop debug.debuggerd.translate.translate_proto_to_text 1 &&
        /data/nativetest64/debuggerd_test/debuggerd_test
Test: for TOMBSTONE in /data/tombstones/tombstone_??; do

08cd23e732 debuggerd: update policy for recent sigaction changes.
Commit 3e235911 in bionic switched LP32's sigaction implementation over
to using the rt_sigaction syscall, matching LP64. Update our seccomp
policy to match.
