2004-10-18Do not embed an ip header with a decremented ttl into an icmp message.Otto Moerbeek
Wait with the decrement until after the copy is done. Resolves checksum mismatches on the embedded header, as reported by tcpdump. ok markus@ itojun@

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@

declarations (extern int foo), and compensate in the appropriate locations.

2002-05-16bring in ECN support from KAME.Kenjiro Cho
it consists of - ECN support in TCP - tunnel-egress and fragment reassembly rules in layer-3 not to lose congestion info at tunnel-egress and fragment reassembly to enable ECN in TCP, build a kernel with TCP_ECN, and then, turn it on by "sysctl -w net.inet.tcp.ecn=1". ok deraadt@

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.
