2013-07-31Move bridge_broadcast and subsequently all IPsec SPD lookup code outMike Belopuhov
of the IPL_NET. pf_test should be no longer called under IPL_NET as well. The problem became evident after the related issue was brought up by David Hill <dhill at mindcry ! org>. With input from and OK mpi. Tested by David and me.
2013-07-23Do not reset the fragment timeout each time a fragment arrives.Alexander Bluhm
Start the expire counter when the queue is created by the first fragment and drop it if the packet could not be reassembled within 60 seconds. Reported by Antonios Atlasis; OK henning@ deraadt@

to only include what is really needed. In particular stop including a "struct ifnet" and move kernel-only definition into the proper #if dance. While here remove the unused spppinfo() from ifconfig. ok guenther@, sthen@, mikeb@

2013-07-04Re-commit: use time_t for storing time_t values. This is an ABIPhilip Guenther
change for pf, but that's fine at this time. You'll need to rebuild pf userland after updating your kernel. change to 'since' member ok henning@ rest ok henning@ deraadt@

2013-06-26put the cksum diff back, of course with the bug fixed where we couldHenning Brauer
under some circumstances repair broken checksums on the way. ok ryan naddy mikeb . redo most of the protocol (tcp/udp/...) checksum handling -assume we have hardware checksum offloading. stop mucking with the checksum in most of the stack -stop checksum mucking in pf, just set a "needs checksumming" flag if needed -in all output pathes, very late, if we figure out the outbound interface doesn't have hw cksum offloading, do the cksum in software. this especially makes the bridge path behave like a regular output path -little special casing for bridge still required until the broadcast path loses its disgusting shortcut hacks, but at least it's in one place now and not all over the stack in6_proto_cksum_out mostly written by krw@ started at k2k11 in iceland more than 1.5 years ago - yes it took that long, this stuff is everything but easy. this happens to fix the infamous pf rdr bug that made us turn off proto cksum offloading on almost all interface drivers.

2013-06-17Before pulling the TCP options from the mbuf onto the stack, do anAlexander Bluhm
additional length check in pf_modulate_sack() and pf_normalize_mss(). Overflow cannot happen due to the restricted values in the length calculation. As this is not obvious, be better safe than sorry. OK henning@
2013-06-17Instead of bcopy() and bcmp() a single pointer in an mbuf tag,Alexander Bluhm
assign with = and compare with == . This way the compiler will check deeper wether the cast is correct. Alignment is fine, tested on sparc64. OK claudio@

2013-06-05after the pf_test_state folding, in pf_test in the proto switch, theHenning Brauer
udp and the default case are 100% identical, tcp does a little more, but that is easier to add w/ two "if tcp" blocks in the default case, so the udp and tcp cases die. ok bluhm
2013-06-04fold pf_test_state_{tcp,udp,other} into one pf_test_state.Henning Brauer
the _icmp variant stays because it is completely different. factor out the synproxy code into a new pf_synproxy() for readability. pf_setup_pdesc sets us up with access to ports, cksum etc in a protocol independent matter, so we don't need many protocol switches here. tcp and udp were almost identical, the _other case changes significantly - not too unlikely this fixes a subtle bug or two in that case. ok ryan benno bluhm mikeb
2013-06-04add a pointer to the protocol checksum header field to pf_pdesc and setHenning Brauer
it up in pf_setup_pdesc(). ok ryan benno mikeb bluhm

just return after being done with the address. ok bluhm ryan mikeb
2013-06-03Link pf states and socket inpcbs together more tightly. The linkingAlexander Bluhm
was only done when a packet traveled up the stack from pf to tcp_input(). Now also link the state and inpcb when the packet is going down from tcp_output() to pf. As a consequence, divert-reply states where the initial SYN does not get an answer, can be handled more correctly. This change is part of a larger diff that has been backed out in 2011. Bring the feature back in small steps to see when bad things start to happen. OK henning deraadt
2013-06-03Update o[sd]port whenever n[sd]port is changed. This fixes aAlexander Bluhm
regression introduced with pf.c 1.827 and allows us to create icmp states again. OK henning@
2013-06-03put back the match member to the anchor stack struct - userland (pfctl)Henning Brauer
uses it. that is so incedibly wrong... sorry for the breakage, folks. found by tedu, SMSing me out of my breakfast bob
2013-06-03Replace "hot" bcopy() calls in ether_output() with memcpy(). This tells theMark Kettenis
compiler that source and destination are not overlapping, allowing for more aggressive optimization, leading to a significant performance improvement on busy firewalls. Reworking of a diff by dlg@, who did the hard work of benchmarking this. ok deraadt@, mikeb@, henning@, mcbride@, tedu@, matthew@
2013-06-03fix anchor quick with nested anchors. we lost the quick flag as soon asHenning Brauer
we stepped into a child anchor. simplify the logic, get rid of the match flag in the anchor stack, just use the match variable we already had (and used in a boolean style) to track the nest level we had a match at. when a child anchor had a match we also have a match in the current anchor, so update the match level accordingly, and thus correctly honour the quick flag. reported by, along with the right idea on how to fix this, by Sean Gallagher \sean at teletech.com.au/, who also helped testing the fix. ok ryan & benno
2013-06-02set up osport and odport (original src/dst port) in pf_setup_pdesc insteadHenning Brauer

Thanks to Brian Poole <pooleb @ gmail ! com> for noticing this.
2013-05-11Set trunk(4)'s MTU to that of the first trunkport. Allows trunk to work withStuart Henderson
jumbo/baby-jumbo frames. To avoid problems with mismatches between trunkports, any additional ports must have the same MTU as already set on the trunk(4). Based on changes made in FreeBSD. Tested by myself and jj@, ok reyk@
2013-05-10Since pf_state_key_attach can decide to free the provided stateMike Belopuhov
key we need to sync our state key pointers with whatever values the function will pick. Not doing so will produce wrong results if address translation must be applied afterwards and we happen to have a state key collision. Then pf_translate will follow an old pointer and punch in garbage addresses into the packet. Noticed, initial patch and tests by Vitaly Sinilin <vs @ kp4 ! ru> ok tedu, henning
