df2e7eb3cc Explain how to get a tombstone proto. 
There's a link here from the javadoc, but a link to the javadoc from
here seems like a good idea.

c95047dd20 Update for accurate unreadable elf files. 
The functionality moved from the Unwinder object to the MapInfo
object and means that the individual unreadable files can be
displayed now.

Included adding the unreadable elfs per thread in the protobuf.

Updated the unwinder test.

Test: All unit tests pass.

5ddcea2924 [MTE] Add a HWASan-style tag dump to tombstones. 
We already dump the tags in the regigster dump section by appending the
tag to the memory address. You only get 2 granules before each register
and 13 after.

The HWASan-style tag dump is extremely useful for debugging, as it gives
a pretty comprehensive overview of the memory subsystem. It also
provides enough context bytes (256) to give you a reasonable intuition
about a particular bug.

The tag dump shows up only if PTRACE_PEEKTAGS returns at least one value
in the 256 requested. If the start of end of the region is untagged,
it's omitted. The tag dump looks like this:

fe751c5a61 Re-add backtrace note about unreadable elf. 
When moving to the proto-ized tombstones, the note about unreadable
elf files in a backtrace got lost. This re-adds it and adds a test
to verify that the note properly shows up.

Test: Ran unit tests.

777148f9f2 Merge "libdebuggerd: store process uptime." 2021-03-23 06:46:05 +00:00
Peter Collingbourne
1a1f7d79a4 Support MTE and GWP-ASan features in proto tombstones. 
Proto tombstones were missing tagged fault addresses, tagged_addr_ctrl,
tags in memory dumps and Scudo and GWP-ASan error reports. Since text
tombstones now go via protos, all of these features broke when we
switched to text tombstones generated from protos by default. Fix
the features by adding support for them to the proto format,
tombstone_proto and tombstone_proto_to_text.
