Andrew Kaster	ddea37b521	Kernel+LibC: Move name length constants to Kernel/API from limits.h ... Reduce inclusion of limits.h as much as possible at the same time. This does mean that kmalloc.h is now including Kernel/API/POSIX/limits.h instead of LibC/limits.h, but the scope could be limited a lot more. Basically every file in the kernel includes kmalloc.h, and needs the limits.h include for PAGE_SIZE.	2023-01-21 10:43:59 -07:00
sin-ack	ef6921d7c7	Kernel+LibC+LibELF: Set stack size based on PT_GNU_STACK during execve ... Some programs explicitly ask for a different initial stack size than what the OS provides. This is implemented in ELF by having a PT_GNU_STACK header which has its p_memsz set to the amount that the program requires. This commit implements this policy by reading the p_memsz of the header and setting the main thread stack size to that. ELF::Image::validate_program_headers ensures that the size attribute is a reasonable value.	2022-12-11 19:55:37 -07:00
Andreas Kling	9eeee24a39	Kernel+LibC: Enforce a limit on the number of supplementary group IDs ... This patch adds the NGROUPS_MAX constant and enforces it in sys$setgroups() to ensure that no process has more than 32 supplementary group IDs. The number doesn't mean anything in particular, just had to pick a number. Perhaps one day we'll have a reason to change it.	2022-08-20 22:39:56 +02:00
