So I have a need to increase the max stack size in the kernel. There currently is no knob to do this. I though of implementing it like the max data size knob (MAXDSIZ). Is this the best answer or should it maybe be done via read only sysctl (and then can be set in the /boot/loader.conf)? I know how to do the former, but I am not sure about the latter.
This (set MAXSSIZ in the same way as MAXDSIZ) is the best answer. There is no point in making it more tunable than MAXDSIZ.
Notes: - MAXSSIZ used to be an option, just like MAXDSIZ. There are ifdefs for both in <machine/vmparam.h>. This was broken by not putting MAXSSIZ in sys/conf/options. - the stack size should normally be limited using login.conf or the stack size rlimit. These don't apply here because MAXSSIZ gives the maximum that can be set using these.
