Andrey Turkin a4122753e6 Initial RISC-V64 support 2024-10-11 06:44:54 +03:00
4lDO2 ec216e56e2 Preserve umask across execv. 2024-09-25 20:28:50 +02:00
4lDO2 7fa5b679cc Move umask to a regular global variable.
The umask value is per-process, so because all POSIX open-like functions
now occur via relibc, this is valid.

4lDO2 e82ced6e4e Fix non-edge-case signal handling on aarch64. 2024-09-24 19:34:52 +02:00
4lDO2 d6396cb4e8 Probably complete aarch64 asm.
It contains all signal logic x86_64 already has, although statistically
it will certainly have a few errors.

4lDO2 09108634cf Set uc_stack properly.
POSIX does not appear to explicitly mention that this should be the
sigaltstack, but other Linux appears to treat it as the sigaltstack.

4lDO2 6dd9332af2 WIP: Handle spurious signals properly.
These can occur in the following scenario:

- thread 1 has blocked signal A
- thread 2 has not blocked signal A
- signal A is sent to a process with thread 1 and thread 2
- thread 1 is simultaneously unblocking signal A, and thus jumps to the
  trampoline
- thread 2 is awoken, but thread 1 won the "fetch_andn" to clear the
  signal bit.

If the signal asm is jumped to automatically after each timer interrupt,
this scenario will also be relatively common due to that.
