LibC: Add MAXPATHLEN to limits.h MAXPATHLEN defines the longest permissable path length after expanding symbolic links. It is used to allocate a temporary buffer from the buffer pool in which to do the name expansion, hence should be a power of two. On UNIX MAXPATHLEN has the same size as PATH_MAX. 2019-09-11 19:37:55 -03:00			`#if !defined MAXPATHLEN && defined PATH_MAX`
Kernel: Move E2BIG calculation from Thread to Process Thread::make_userspace_stack_for_main_thread is only ever called from Process::do_exec, after all the fun ELF loading and TSS setup has occured. The calculations in there that check if the combined argv + envp size will exceed the default stack size are not used in the rest of the stack setup. So, it should be safe to move this to the beginning of do_exec and bail early with -E2BIG, just like the man pages say. Additionally, advertise this limit in limits.h to be a good POSIX.1 citizen. :) 2019-10-20 10:11:40 -06:00			`# define MAXPATHLEN PATH_MAX`
