v23.0 - 2022-01-11:
Tracing service and probes:
* Added workaround for a kernel ftrace bug causing some "comm" fields to be
not null-terminated. https://github.com/torvalds/linux/commit/f0a5157803 .
* Added ability to talk to the newer AIDL-based health hal in traced_probes.
It still falls back on the older HIDL interface for older devices.
Trace Processor:
* Changed the argument for the trace path in constructor of TraceProcessor
in the Python API from |file_path| to |trace|.
|file_path| is deprecated and may be removed in the future.
* Changed the Python API constructor. Now it takes a TraceProcessorConfig
instead of passing parameters directly. This may break existing code
but migration should be trivial (all current options are still
supported).
* Fixed a HTTP keepalive bug in trace_processor --httpd. The bug, introduced
in v22.0, caused each RPC request to close the connection, effectively
defeating the 'Connection: Keep-Alive', after each query made by the UI.
* Added parsing of netif_receive_skb events from proto traces.
* Added android_netperf metric based on netif events.
* Fixed a bug that would cause fetch errors when loading traces > 32 MB when
using trace_processor --httpd.
* Added a workaround to tokenize properly /proc/pid/cmdline for chrome
processes on Linux/CrOS. Chrome rewrites its cmdline replacing \0 -> ' '.
