2011-03-24Reassemble IPv6 fragments in pf. In the forward case, pf refragmentsAlexander Bluhm
the packets with the same maximum size. This allows the sender to determine the optimal fragment size by Path MTU Discovery. testing sthen@ matthieu@ ok claudio@

2011-03-07Declare the inline function pf_addr_compare() non-static in pfvar.hAlexander Bluhm
to make it reusable by pf fragment reassembly. No functional change. discussed with henning@, claudio@, deraadt@, kettenis@ ok guenther@

and make it void. ok henning@, markus@, mcbride@
2011-03-02when sending deferred packets use ip6_output for v6 frames instead ofDavid Gwynne

problem was reported by babut at yandex dot ru in the pr 6564, tested by the pr originator and me, ok henning mcbride. shaves off a bunch of XXXs.
2011-02-18when changing the vlandev of a running vlan(4) interface, we also need toReyk Floeter
move the configured multicast addresses and preserve the promisc mode settings of the parent. this fixes an issue when carp stopped working on a vlan after the vlandev was manually changed. ok naddy@ phessler@

using address ranges (e.g. "10.1.1.1 - 10.1.1.5") did not match addresses correctly on little-endian systems. ok henning@

2011-02-06pf_translate() may be called from pflog_packet(). Make sure thatAlexander Bluhm
IPv4-ICMP6 and IPv6-ICMP packets are not rewritten in case they are dropped and logged. spotted by mikeb@; ok henning@
2011-02-06pf_test() and pf_test6() drop IPv4-ICMP6 and IPv6-ICMP packets. DoAlexander Bluhm
not do the same check in pf_test_rule() again. ok henning
2011-02-05When a packet with an unusual protocol number got rewritten, theAlexander Bluhm
header lenght was uninitialized. This resulted in a panic in m_clget(). Initialize hdrlen with 0 and call m_copyback() only if necessary. ok henning@
2011-02-01The check for invalid IPv6 fragment size in pf_normalize_ip6() wasAlexander Bluhm
wrong. As an effect small valid fragmented packets got dropped and some invalid fragmented packets were passed. plen is the payload lenght of the ipv6 packet without the ipv6 header. off is relative to the whole packet including the ipv6 header. Add sizeof(struct ip6_hdr) in the calculation. ok henning@ markus@

2011-01-20The reason accounting in pf_reassemble() was not correct. ChangeAlexander Bluhm
pf_reassemble() to return PF_DROP or PF_PASS and *m0 is NULL or the reassembled packet. In case of PF_DROP, the mbuf must be valid, e.g. for logging, and will be freed later. In case the reassembled packet is too big, use the reassembled mbuf for PF_DROP. ok henning@ markus@
2011-01-19Give pf_normalize_ip() the same 3 way semantics as pf_test().Alexander Bluhm
- PF_DROP, the packet is bad, the mbuf still exists and must be freed. - PF_PASS and *m0 is NULL, the packet has been processed, not an error. - PF_PASS and *m0 is not NULL, continue with packet processing. This fixes a potential mbuf use after free. ok henning@ markus@ mpf@
2011-01-18When changing the ifa_broadaddr broadcast address, ifa_update_broadaddr()Alexander Bluhm
copied the pointer to the sockaddr instead of the content of sockaddr_in. As the source of the data resides on the stack, the pointer got invalid later and the kernel crashed. As only addresses with fixed size are used, sa_len bytes of the sockaddr can be coppied. ok krw@ markus@ mpf@ claudio@ henning@
2011-01-12Never include SADB_X_EXT_REMOTE_AUTH (which is either aMike Belopuhov
passphrase or an RSA key) in the reply message. There's nothing that justifies this behavior and PF_KEY RFC prefers to exclude keys and other sensitive material from replies. Discussed with reyk, no objections from deraadt.
2011-01-11for key material that is being being discarded, convert bzero() toTheo de Raadt

2011-01-11delay deferred packets for a maximum of 20ms instead of 100 ticks (whichDavid Gwynne
varies by arch). the 20ms is still up for discussion. ok deraadt@
2011-01-10If pf_test() was called recursively, the global variable pf_hdrsAlexander Bluhm
could be used multiple times for different packets. This happened when pflow(4) was used. Instead of a global variable, store the pf_headers in a local variable on the stack. david@ found the bug, narrowed it down and tested the fix. ok henning@

2011-01-06dst my point to memory inside rt so move the check up before theClaudio Jeker
rtfree(rt). Without this the sp_protocol on RTM_DELETE is garbage and rtsocket user that restrict the AF of the socket (like ospfd) will not see a single one of the RTM_DELETE. OK henning@, dlg@

2011-01-03Allow to change vlan options of existing vlan(4)/svlan(4) devices atReyk Floeter
runtime instead of forcing the user to-recreate the interface with the changed options. The code now re-configures the interface instead of returning EBUSY. For example, it is now possible to run "ifconfig vlan1 vlandev em0; ifconfig vlan1 vlandev em1" in a sequence. ok claudio@ deraadt@
2010-12-31Remove dead code from pf_norm.c. The fragment cache is some leftoverAlexander Bluhm
from fragment crop. PFFRAG_NOBUFFER and PFFRAG_DROP are never set. pf_cache_pl and pf_cent_pl have no pool_get. ok henning@

2010-12-21Convert netisr to a normal soft interrupt instead of hanving MD codeClaudio Jeker
for it. This makes the netisr a real C function which will help further development. No noticable performance change on i386 and amd64. With input from kettenis@ and miod@ additional OKs mikeb@ and henning@
2010-12-15Be more careful when copying the pf rule from userland into the kernel.Claudio Jeker
All pointers in the struct need to be cleared and reset. So instead of bcopy the struct and clear some fields start with a clean struct and assign the values that need to be copied. Fixes a local vulnerability but only root can issue the problematic ioctl(). Reported by Jean Sigwald, has been in snaps for a while and OK deraadt@
