rmind f04a92b1d6 - Rewrite parts of pfil(9): use array to store hooks and thus be more cache 
friendly (there are only few hooks in the system).  Make the structures
  opaque and the interface more strict.
- Remove PFIL_HOOKS option by making pfil(9) mandatory.

christos 27fe772ddc IPSEC has not come in two speeds for a long time now (IPSEC == kame, 
FAST_IPSEC). Make everything refer to IPSEC to avoid confusion.

christos 025acb1dac conditionalize the net traversal code on FAST_IPSEC to make rump build. 2013-06-05 00:48:32 +00:00
christos 213e873fd6 PR/47886: Dr. Wolfgang Stukenbrock: IPSEC_NAT_T enabled kernels may access 
outdated pointers and pass ESP data to UPD-sockets.
While here, simplify the code and remove the IPSEC_NAT_T option; always
compile nat-traversal in so that it does not bitrot.

pooka 83023c7fae Give portalgo a compile-time override; for cases where the default default 
doesn't make enough sense to even consider it (a lot of outgoing connections
from rump kernels with local port 65535).

joerg 89a508fbb5 Systematically include sys/featuretest.h when _NETBSD_SOURCE is used. 
Some are redundant, but make verification with grep much easier.

christos e26dacd5b3 - Do the size checks before calling the cpu checksum code. Otherwise you'll 
crash there and not panic.
- Don't panic on short packets unless DIAGNOSTIC. In general we should try
  to make the kernel survive errors...

spz 9d545ae650 <grmbl>whitespace</grmbl> 2012-07-19 21:08:42 +00:00
spz 8fda128ab3 this commit contains two sets of unrelated changes: 
"while I was here" I checked other KAME implementations for their icmp6.h
version, and thus:
  - added a define for MLDV2_LISTENER_REPORT from FreeBSD
  - added defines for the missing ICMP6_DST_UNREACH codes

then on to what I actually wanted to do:
  - adds strings for the types and codes (encapsulated by ICMP6_STRINGS)
    for the use of npfctl and other tools that might want to parse
    human-friendly names instead of the corresponding number for ipv6-icmp
    types and codes.
    The strings are ordered such that their index is (as far as is practical)
    the number belonging to the name, which is why there are
    icmp6_type_err (use directly) and icmp6_type_info (add 128)

christos 40114b997c PR/46602: Move the rfc6056 port randomization to the IP layer. 2012-06-22 14:54:34 +00:00
yamt 365b42c39d for the default "bsd" algorithm, restore the pre rfc6056 changes behaviour. 
fix anonportmin/max.

probably other algorithms need similar fixes.
