I'm trying to use IPSEC with IPv6 in transport mode. My configuration is
simple: IPSEC + racoon from ipsec-utils.
One side is RS(MIPS) with HEAD-r252464 and 2nd side ALIX(i386) with
9.1-STABLE. This error is visible only on MIPS side.
ipsec.conf:
spdadd [ipv6_addr1] [ipv6_addr2] any -P in ipsec
esp/transport//require;
spdadd [ipv6_addr2] [ipv6_addr1] any -P out ipsec
esp/transport//require;
And the error is reproducible with just getting transmission over the IPSEC:
Trap cause = 2 (TLB miss (load or instr. fetch) - kernel mode)
