net.inet.ipsec.test_replay - When set to 1, IPsec will send packets with
the same sequence number. This allows to verify if the other side
has proper replay attacks detection.
net.inet.ipsec.test_integrity - When set 1, IPsec will send packets with
corrupted HMAC. This allows to verify if the other side properly
detects modified packets.

By Pawel Jakub Dawidek <pjd@FreeBSD.org>.
Discussed with Christos Zoulas and Jonathan Stone.
The __UNCONST macro is now used only where necessary and the RW macros
are gone. Most of the changes here are consumers of the
sysctl_createv(9) interface that now takes a pair of const pointers
which used not to be.
Rework usr.bin/netstat/fast_ipsec.c to find the stats nodes under the
new names (Kame uses the name stats so we use different ones), as well
as setting slen appropriately between calls to sysctlbyname(), and
providing forward compatibility when actually retrieving stats via
sysctlbyname().
And correct a spelling error.
Add 'XXX FIXME' comments to ah4_ctlinput(), esp4_ctlinput()
ipcode-paths merely cast away local variables ip, ah/esp, sav; the
fast-ipsec IPv4 code appears to work even so.
In espv6_ctlinput(), call the fast-ipsec KEY_ALLOCSA()/KEY_FREESA()
macros, not the KAME-native key_allocsa()/key_freesa() functions.
Cast sa6_src/sa6_dst to void; the fast-ipsec API does not (yet) pass
both src and dst addrs to KEY_d-ALLOCSA/KEY_FREESA.
Make sure 'off' is set to 0 on the branch where it was formerly
used-before-set.
Will now compile with ``options INET6'' (as in
sys/arch/i386/conf/GENERIC.FAST_IPSEC), but is not yet
expected to acutally work with IPv6.
used to short-circuit IPsec processing in other places.
This is enabled only for NetBSD at the moment; in order for it to function
correctly, ipsec_pcbconn() must be called as appropriate.
Remove #ifdef FAST_IPSEC/#endif around the inclusion of local
(sys/netipsec) header files; they are always appropriate for
this file (sys/netipsec/ipsec_netbsd.c). At least on NetBSD.
If INET6 is defined, include appropriate header files
(local netipsec/ipsec6.h, netinet6/ip6protosw.h, and icmp6.h
from its standards-compliant location in netinet/).
Will now at least compile and link when ``options INET6' is configured.
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.
PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.
repository by christos was part 1). netipsec should now be back as it
was on 2003-09-11, with some very minor changes:
1) Some residual platform-dependent code was moved from ipsec.h to
ipsec_osdep.h; without this, IPSEC_ASSERT() was multiply defined. ipsec.h
now includes ipsec_osdep.h
2) itojun's renaming of netipsec/files.ipsec to netipsec/files.netipsec has
been left in place (it's arguable which name is less confusing but the
rename is pretty harmless).
3) Some #endif TOKEN has been replaced by #endif /* TOKEN */; #endif TOKEN
is invalid and GCC 3 won't compile it.
An i386 kernel with "options FAST_IPSEC" and "options OPENCRYPTO" now
gets through "make depend" but fails to build with errors in ip_input.c.
But it's better than it was (thank heaven for small favors).
Fast-IPsec is a rework of the OpenBSD and KAME IPsec code, using the
OpenCryptoFramework (and thus hardware crypto accelerators) and
numerous detailed performance improvements.
This import is (aside from SPL-level names) the FreeBSD source,
imported ``as-is'' as a historical snapshot, for future maintenance
and comparison against the FreeBSD source. For now, several minor
kernel-API differences are hidden by macros a shim file, ipsec_osdep.h,
which (aside from SPL names) can be targeted at either NetBSD or FreeBSD.
