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

MFC: fix multicast routing KLD support, including some minor bug fixes

2002-11-20T23:20:55Z

(see 1.83 of ip_mroute.c). In detail: conf/files ip_mroute optional mrouting net/route.c remove useless #include, MFC mrouting KLD support netinet/ip_encap.c remove useless #include, access ipip_input through a function pointer (only a partial MFC -- -current has a better solution). fix interface to encap4_input() to avoid varargs netinet/ip_encap.h remove __P, fix interface to encap4_input netinet/ip_input.c MFC: mrouting KLD support, and move here rsvp_input() together with the rest of the rsvp code. netinet/ip_mroute.[ch] MFC 1.83 mrouting cleanup and KLD support netinet/ip_output.c MFC mrouting KLD support netinet/ip_var.h MFC support for mrouting KLD netinet/raw_ip.c MFC support for mrouting KLD Also some innocuous style cleanup (fix function headers, remove register, etc.) which have slipped in and i am too fed up to remove yet another time (and rerun all the kernel builds with all possible combinations of relevant options to make sure their removal does not introduce bugs).

Initial part (style only) of MFC 1.83:

2002-11-19T23:03:05Z

+ remove __P() and register + fix function headers + fix indentation + remove redundant casts + remove unused conditional code + replace 0 with INADDR_ANY or NULL where applicable + remove initialization to 0 of global variables as this is default for bss This commit is cosmetic only, so it does not include any of the (minor) bugfixes or code rearrangements of 1.83, nor it makes the mrouting code work as a module.

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.
