MFC: m_tag support

2003-01-23T21:06:48Z

Replace aux mbufs with packet tags: o instead of a list of mbufs use a list of m_tag structures a la openbsd o for netgraph et. al. extend the stock openbsd m_tag to include a 32-bit ABI/module number cookie o for openbsd compatibility define a well-known cookie MTAG_ABI_COMPAT and use this in defining openbsd-compatible m_tag_find and m_tag_get routines o rewrite KAME use of aux mbufs in terms of packet tags o eliminate the most heavily used aux mbufs by adding an additional struct inpcb parameter to ip_output and ip6_output to allow the IPsec code to locate the security policy to apply to outbound packets o bump __FreeBSD_version so code can be conditionalized o fixup ipfilter's call to ip_output based on __FreeBSD_version

just merged cosmetic changes from KAME to ease sync between KAME and FreeBSD. (based on freebsd4-snap-20020128)

- net.inet.ipsec.esp_auth hasn't been there - nuke all debug printfs, which are unneeded by now. - get rid of #ifdef IPSEC_DEBUG in headers - now that key_debug_level is always defined, there's no need for #ifdef IPSEC_DEBUG around sysctl MIB code (net.key.debug). - switch all debug printf() to ipseclog(). - When there is no suitable inbound policy for the packet of the ipsec tunnel mode, the kernel never decapsulate the tunneled packet as the ipsec tunnel mode even when the system wide policy is "none". Then the kernel leaves the generic tunnel module to process this packet. If there is no rule of the generic tunnel, the packet is rejected and the statistics will be counted up. sys/netinet6/ipsec.c: 1.14 sys/netkey/key.c: 1.32-1.35 sys/netkey/key_debug.c: 1.16 sys/netkey/key_debug.h: 1.8 sys/netkey/key_var.h: 1.5 sys/netkey/keysock.c: 1.8

MFC 1.13: Fixed to process a IPv6 packet when ah transport after esp tunnel

should be applied. the SA of AH transport could not be selected from the SAD because of this bug.

MFC: Add ``options RANDOM_IP_ID'' which randomizes the ID field of IP

packets. This closes a minor information leak which allows a remote observer to determine the rate at which the machine is generating packets, since the default behaviour is to increment a counter for each packet sent.

MFC: Sync with recent KAME.
