2005-10-05Add multicast routing to GENERIC.Esben Norby
It is now possible to enable multicast routing in the kernel with the sysctl option net.inet.ip.mforwarding=1 Based on intial work by msf@ help claudio@ ok claudio@ deraadt@

2005-08-11New counter for not joined IPv4 multicast groups.Marco Pfatschbacher
Don't count link local scope multicast as not forwardable. This stops ips_cantforward growing on carp(4) networks. tested and ok mcbride@, ok markus@.
2005-07-31Change the API for icmp_do_error so that it takes the mtu directly, ratherChristopher Pascoe
than a pointer to struct ifnet containing it. Saves a 448 byte stack allocation in ip_forward which previously faked up a struct ifnet just for this purpose. idea ok deraadt millert

2004-06-06extend routing table to be able to match and route packets based onCedric Berger
their *source* IP address in addition to their destination address. routing table "destination" now contains a "struct sockaddr_rtin" for IPv4 instead of a "struct sockaddr_in". the routing socket has been extended in a backward-compatible way. todo: PMTU enhancements, IPv6. ok deraadt@ mcbride@

2002-08-28Fix a problem where passing NULL as a pointer with varargs does not promotePer Fogelstrom
NULL to full 64 bits on a 64 bit address system. Soultion is to add a (void *) cast before NULL. This makes a 64 bit MIPS kernel work and will probably help future 64 bit ports as well. OK from art@

2002-01-25Add a drain hook to each pool. This hook is called in three cases.Artur Grabowski
1. When a pool hit the hard limit. Just before bailing out/sleeping. 2. When an allocator fails to allocate memory (with PR_NOWAIT). 3. Just before trying to reclaim some page in pool_reclaim. The function called form the hook should try to free some items to the pool if possible. Convert m_reclaim hooks that were embedded in MCLGET, MGET and MGETHDR into a pool drain hook (making the code much cleaner).
2002-01-23Pool deals fairly well with physical memory shortage, but it doesn't dealArtur Grabowski
well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.

2001-06-27ALTQ base modifications to the kernel.Kenjiro Cho
- ALTQ introduces a set of new queue macros that coexist with the traditional IF_XXX macros. - "struct ifaltq" replaces "struct ifqueue" in "struct ifnet". - assign cdev major 74 for i386 and 54 for alpha as ALTQ control interface.
