kamil 5e901b7cba Update TODO.sanitizers
Reflect with reality the fts(3) entry as handling compar callback is the
only feature still missing.

Add a new entry for utime(3), we expect to allow changing actime regardless
of noatime mount property.

Sanitizer and related tasks.
Short term:
- compiler-rt import and integration with base
- merge TSan, MSan and libFuzzer ATF tests
- prepare MKSANITIZER readme
- upstream local patches, mostly to compiler-rt
Long term:
- handle fts_open(3) compar callback in sanitizers (use TLS to store
the real callback and call a wrapper that will [un]poison appropriate
memory regions)
- investigate and address the libcxx failing tests on NetBSD
- FILE and DIR sanitization (needed by at least: ESan, MSan)
- add missing interceptors (mostly MSan-centric)
- improve the framework for ioctl(2) database and handle special cases when a
part of a struct can be uninitialized and passed to the kernel (MSan)
- port or finish the port of:
* ESan,
* LSan,
* XRay,
* shadowcallstack,
* cfi,
* scudo,
* profile,
* DFSan.
- finish the research of a new syscall for StopTheWorld() operation
ptrace(2) style for self-introspection and debugging (LSan)
- port HWASan -- aarch64 specific, needs hardware or emulator
- make MKSANITIZER usable with any supported by a compiler combination of
sanitizers
- detect and fix more bugs in basesystem
- pkgsrc integration with sanitizers and MKSANITIZER (PKGSANITIZER?)
- port what possible to !amd64
- fixes with the signal code
- attach a NetBSD buildbot testing build of compiler-rt and executing tests
- make compiler-rt buildable with GCC
- finish the support of float128 for Clang/LLVM/libstdc++/libgcc
- lld port to NetBSD (GNU ld(1) is too slow for serious LLVM development)
- merge of the libFuzzer integration with the basesystem
- oom-killer ATF tests and fixes
- uvm_map.c E2BIG workaround or limit raise (1MB -> 10MB?), needed by libFuzzer
- utime(3) allow changing actime regardless of noatime mount property
Unspecified:
- kernel-tsan? upstream development is stalled with patches for Linux 4.2
https://github.com/google/ktsan
- kernek-msan? in development for Linux
https://github.com/google/kmsan
- kernel-safestack? implemented in Fuchsia/Magenta
- kernel coverage (KCOV?)
- syzkaller port
