* pkg/report: add parsing of trusty crashesDmitry Vyukov2019-01-141-0/+25
| | | | Update #933
* pkg/report: ignore arch/.*/mm/physaddr.c as guilty fileDmitry Vyukov2018-10-101-0/+51
| | | | | | | This is called from kfree in the added test. We already ignore everything related to kmalloc/free and e.g. arch/.*/mm/fault.c, so it looks reasonable to ignore this one too.

* pkg/report: fix guilty file extractionDmitry Vyukov2018-09-262-0/+78
| | | | | Account for the case that some file names can appear _before_ crash report starts. Start extracting guilty file starting from StartPos.

* pkg/report: don't blame kcovDmitry Vyukov2018-04-061-0/+63
| | | | kcov frame can be present in rcu stalls, ignore it.
* pkg/report: add few KMSAN report examplesDmitry Vyukov2018-03-262-0/+165

* pkg/report: special-case extraction of guilty file for rcu stallsDmitry Vyukov2018-02-072-4/+2

* pkg/report: improve report titlesDmitry Vyukov2018-02-063-0/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Replace stacktraceRe with custom code which is more flexible. stacktraceRe stumbled on any unrelated lines and could not properly parse truncated stacks. 2. Match report regexp earlier. If we match simler title regexp, but don't match report regexp or fail to parse stack trace, the report is corrupted. This eliminates lots of duplicate corrupted oops entries, which were there only because we had complex regexp's in titles. 3. Ignore low-level frames during stack parsing. E.g. we never want to report a GPF in lock_acquire or memcpy (somewhat similar to what we do for guilty files). 4. Add a bunch of specialized formats for WARNINGs. There is number of generic debugging facilities (like ODEBUG, debug usercopy, kobject, refcount_t, etc), and the bug is never in these facilities, it's in the caller instead. 5. Improve some other oops formats. 6. Add a bunch of additional tests. This resolves most of TODOs in tests. Fixes #515

* pkg/report: move guilty file test data to testdir/Dmitry Vyukov2017-12-1225-0/+838
linux_test.go is total mess and very hard to work with. Turns out we had 2 tests that do exactly the same (verify Report), but nobody ever noticed. Move all test data to testdir/. One file per crash.
