| | | | | | | | | | | | | | | | | | | | | | in6_if2idlen: treat bridge(4) interfaces like other Ethernet interfaces bridge(4) interfaces have an if_type of IFT_BRIDGE, rather than IFT_ETHER, even though they only support Ethernet-style links. This caused in6_if2idlen to emit an "unknown link type (209)" warning to the console every time it was called. Add IFT_BRIDGE to the case statement in the appropriate place, indicating that it uses the same IPv6 address format as other Ethernet-like interfaces.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mld_v2_dispatch_general_query() is used by mld_fasttimo_vnet() to send a reply to the MLDv2 General Query. In case when router has a lot of multicast groups, the reply can take several packets due to MTU limitation. Also we have a limit MLD_MAX_RESPONSE_BURST == 4, that limits the number of packets we send in one shot. Then we recalculate the timer value and schedule the remaining packets for sending. The problem is that when we call mld_v2_dispatch_general_query() to send remaining packets, we queue new reply in the same mbuf queue. And when number of packets is bigger than MLD_MAX_RESPONSE_BURST, we get endless reply of MLDv2 reports. To fix this, add the check for remaining packets in the queue. PR: 204831

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix possible use after free due to security policy deletion. When we are passing mbuf to IPSec processing via ipsec[46]_process_packet(), we hold one reference to security policy and release it just after return from this function. But IPSec processing can be deffered and when we release reference to security policy after ipsec[46]_process_packet(), user can delete this security policy from SPDB. And when IPSec processing will be done, xform's callback function will do access to already freed memory. To fix this move KEY_FREESP() into callback function. Now IPSec code will release reference to SP after processing will be finished.

Remove check for presence PACKET_TAG_IPSEC_IN_DONE mbuf tag from ip_ipsec_fwd(). PACKET_TAG_IPSEC_IN_DONE tag means that packet is already handled by IPSEC code. This means that before IPSEC processing it was destined to our address and security policy was checked in the ip_ipsec_input(). After IPSEC processing packet has new IP addresses and destination address isn't our own. So, anyway we can't check security policy from the mbuf tag, because it corresponds to different addresses. We should check security policy that corresponds to packet attributes in both cases - when it has a mbuf tag and when it has not.

The changed block of code in ip*_ipsec_input() is called when packet has ESP/AH header. Presence of PACKET_TAG_IPSEC_IN_DONE mbuf tag in the same time means that packet was already handled by IPSEC and reinjected in the netisr, and it has another ESP/AH headers (encrypted twice?). Since it was already processed by IPSEC code, the AH/ESP headers was already stripped (and probably outer IP header was stripped too) and security policy from the tdb_ident was applied to those headers. It is incorrect to apply this security policy to current headers. Also make ip_ipsec_input() prototype similar to ip6_ipsec_input().

They aren't used in FreeBSD. Instead check presence of PACKET_TAG_IPSEC_OUT_DONE mbuf tag. If it is found, bypass security policy lookup as described in the comment. PACKET_TAG_IPSEC_OUT_DONE tag added to mbuf when IPSEC code finishes ESP/AH processing. Since it was already finished, this means the security policy placed in the tdb_ident was already checked. And there is no reason to check it again here. Obtained from: Yandex LLC Sponsored by: Yandex LLC TAG: IPSEC-HEAD Issue: #4841
