After r253088, systems with IPSEC and KSTACK_PAGES < 4 crashes on
booting into multi-user mode.
The crash is due to sysctl -a in /etc/rc.d/initrandom ended up with
kernel stack overflow.
where type is struct ipsecstat which is 12560 bytes of size (larger than
3 pages) of size when processing net.inet.ipsec.ipsecstats.
Hi,
Only few fields of struct ipsecstat is used, the rest fields are never
updated. We can split it to several structures, or just remove unused
fields. What is better?
Not storing it on the stack?
Also, I already prepared patch to test.
'both'.. one isn't supposed to have structures of any size on the
stack in the kernel.
At one stage the max was 64 bytes.. has grown since then obviously.
*And* it could do with simplification.
