#define __NR_sigaltstack 131
https://man7.org/linux/man-pages/man2/sigaltstack.2.html
tl;dr:
manage an alternative signal stack
pretty much there just to let you handle SIGSEGVs from stack overflows.
i always read this syscall as "sigal stack", like the manpages are baby talking at me lol. for that reason, i rather like it, but it's got a pretty niche use case. have any of you anons ever had occasion to use it before?
