* Merge netipsec/key.c:1.17 into KAME pfkey implementation:rwatson2004-09-301-5/+0
| | | | | | | | | | | | | | | date: 2004/09/26 02:01:27; author: sam; state: Exp; lines: +0 -5 Correct handling of SADB_UPDATE and SADB_ADD requests. key_align may split the mbuf due to use of m_pulldown. Discarding the result because of this does not make sense as no subsequent code depends on the entire msg being linearized (only the individual pieces). It's likely something else is wrong here but for now this appears to get things back to a working state. Submitted by: Roselyn Lee This change was also made in the KAME CVS repository as key.c:1.337 by itojun.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - share policy-on-socket for listening socket. - don't copy policy-on-socket at all. secpolicy no longer contain spidx, which saves a lot of memory. - deep-copy pcb policy if it is an ipsec policy. assign ID field to all SPD entries. make it possible for racoon to grab SPD entry on pcb. - fixed the order of searching SA table for packets. - fixed to get a security association header. a mode is always needed to compare them. - fixed that the incorrect time was set to sadb_comb_{hard|soft}_usetime. - disallow port spec for tunnel mode policy (as we don't reassemble). - an user can define a policy-id. - clear enc/auth key before freeing. - fixed that the kernel crashed when key_spdacquire() was called because key_spdacquire() had been implemented imcopletely. - preparation for 64bit sequence number. - maintain ordered list of SA, based on SA id. - cleanup secasvar management; refcnt is key.c responsibility; alloc/free is keydb.c responsibility. - cleanup, avoid double-loop. - use hash for spi-based lookup. - mark persistent SP "persistent". XXX in theory refcnt should do the right thing, however, we have "spdflush" which would touch all SPs. another solution would be to de-register persistent SPs from sptree. - u_short -> u_int16_t - reduce kernel stack usage by auto variable secasindex. - clarify function name confusion. ipsec_*_policy -> ipsec_*_pcbpolicy. - avoid variable name confusion. (struct inpcbpolicy *)pcb_sp, spp (struct secpolicy **), sp (struct secpolicy *) - count number of ipsec encapsulations on ipsec4_output, so that we can tell ip_output() how to handle the packet further. - When the value of the ul_proto is ICMP or ICMPV6, the port field in "src" of the spidx specifies ICMP type, and the port field in "dst" of the spidx specifies ICMP code. - avoid from applying IPsec transport mode to the packets when the kernel forwards the packets.

* Lock struct pgrp, session and sigio.tanimura2002-02-231-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | New locks are: - pgrpsess_lock which locks the whole pgrps and sessions, - pg_mtx which protects the pgrp members, and - s_mtx which protects the session members. Please refer to sys/proc.h for the coverage of these locks. Changes on the pgrp/session interface: - pgfind() needs the pgrpsess_lock held. - The caller of enterpgrp() is responsible to allocate a new pgrp and session. - Call enterthispgrp() in order to enter an existing pgrp. - pgsignal() requires a pgrp lock held.

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.

| | | | | | | | | | | | | | | | | | This work was based on kame-20010528-freebsd43-snap.tgz and some critical problem after the snap was out were fixed. There are many many changes since last KAME merge. TODO: - The definitions of SADB_* in sys/net/pfkeyv2.h are still different from RFC2407/IANA assignment because of binary compatibility issue. It should be fixed under 5-CURRENT. - ip6po_m member of struct ip6_pktopts is no longer used. But, it is still there because of binary compatibility issue. It should be removed under 5-CURRENT.

Remove includes of <stddef.h> in kernel code. NB: Kernelcode should *never* include from /usr/include ! Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.
