f41fee5879 trusty: Generic parameterizable TIPC fuzzer

ec1d6caec3 Merge "trusty: Increase maximum number of coverage counters" 2021-02-25 06:22:39 +00:00

0ecf0530db trusty: Increase maximum number of coverage counters 
The keymaster TA has 30841 distinct coverage counters, so 0x4000 counter
slots is not enough to handle this TA. Increase maximum number of
coverage counters to 0x8000.

Test: adb shell trusty_keymaster_fuzzer

cb89889af3 trusty: fuzz: Link to libtrusty dynamically 
libtrusty can be depended on by multiple thing in a fuzzer's
dependencies tree. It's no longer convenient to link to statically.

Leave tests statically linked. Test infra doesn't seem to handle shared
test libs correctly.

6735f8475e trusty: Increase limit on coverage counters 
Keymaster has more than 4096 counters, so we need to allocate a larger
section for the libfuzzer extra counters. Increases the size of the
extra counters section to 16384.

c602562bb2 trusty: Add vendor variant of libtrusty_coverage 
We want to add coverage statistics to the trusty-ut-ctrl tool, which is
a vendor binary. Thus we need a vendor variant of libtrusty_coverage.
Merges system libtrusty_test and vendor libtrusty into a single
vendor_available library so that we can add vendor_available to
libtrusty_coverage and make it accessible from vendor tools.

e962930d19 trusty: Retrieve coverage PCs from coverage record 
Adds the ability to retrieve and save program counter information from
the trusty coverage record data. PC information is saved to a .sancov
file, parseable by the LLVM sancov tool. Sancov can then symbolize and
display this coverage information for consumption by humans.

Adds a sancov dump to the libtrusty_coverage_test for testing.

Test: atest libtrusty_coverage_test
