2019-10-16Fix syscall changes lost in rebaseMichael Pratt
These syscalls were changed in the amd64 file around the time the arm64 PR was sent out, so their changes got lost. Updates #63 PiperOrigin-RevId: 275114194

2019-10-15Remove panic when reassembly fails.Bhasker Hariharan
Reassembly can fail due to an invalid sequence of fragments being received. eg. Multiple fragments with same id which claim to be the last one by setting the more flag to 0 etc. It's safer to just drop the reassembler and increment a metric than to panic when reassembly fails.

2019-10-15Set NDP hop limit in accordance with RFC 4861Tamir Duberstein
...and do not populate link address cache at dispatch. This partially reverts 313c767b0001bf6271405f1b765b60a334d6e911, which caused malformed packets (e.g. NDP Neighbor Adverts with incorrect hop limit values) to populate the address cache. In particular, this masked a bug that was introduced to the Neighbor Advert generation code in 7c1587e3401a010d1865df61dbaf117c77dd062e. PiperOrigin-RevId: 274865182

2019-10-10Allow for zero byte iovec with MSG_PEEK | MSG_TRUNC in recvmsg.Ian Lewis
This allows for peeking at the length of the next message on a netlink socket without pulling it off the socket's buffer/queue, allowing tools like 'ip' to work. This CL also fixes an issue where dump_done_errno was not included in the NLMSG_DONE messages payload. Issue #769 PiperOrigin-RevId: 274068637

2019-10-10Fix bugs in fragment handling.Bhasker Hariharan
Strengthen the header.IPv4.IsValid check to correctly check for IHL/TotalLength fields. Also add a check to make sure fragmentOffsets + size of the fragment do not cause a wrap around for the end of the fragment. PiperOrigin-RevId: 274049313

2019-10-03Implement proper local broadcast behaviorChris Kuiper
The behavior for sending and receiving local broadcast (255.255.255.255) traffic is as follows: Outgoing -------- * A broadcast packet sent on a socket that is bound to an interface goes out that interface * A broadcast packet sent on an unbound socket follows the route table to select the outgoing interface + if an explicit route entry exists for 255.255.255.255/32, use that one + else use the default route * Broadcast packets are looped back and delivered following the rules for incoming packets (see next). This is the same behavior as for multicast packets, except that it cannot be disabled via sockopt. Incoming -------- * Sockets wishing to receive broadcast packets must bind to either INADDR_ANY (0.0.0.0) or INADDR_BROADCAST (255.255.255.255). No other socket receives broadcast packets. * Broadcast packets are multiplexed to all sockets matching it. This is the same behavior as for multicast packets. * A socket can bind to 255.255.255.255:<port> and then receive its own broadcast packets sent to 255.255.255.255:<port> In addition, this change implicitly fixes an issue with multicast reception. If two sockets want to receive a given multicast stream and one is bound to ANY while the other is bound to the multicast address, only one of them will receive the traffic.
