2020-10-28Add the payload directly to the ICMPv4 typeArthur Sfez
This makes handling inbound fragmented packets easier, because a fragmented packet might not have an actual ICMP header but only a payload. After this change, the ICMPv4 is the last layer you can get because the payload is embedded in it. Note that this makes it consistent with the ICMPv6 implementation. While I'm here, I've also added the Ident and Sequence fields on the ICMPv4 type. Defaults are still zero. PiperOrigin-RevId: 339577094

2020-10-27Add support for Timestamp and RecordRoute IP optionsJulian Elischer
IPv4 options extend the size of the IP header and have a basic known format. The framework can process that format without needing to know about every possible option. We can add more code to handle additional option types as we need them. Bad options or mangled option entries can result in ICMP Parameter Problem packets. The first types we support are the Timestamp option and the Record Route option, included in this change. The options are processed at several points in the packet flow within the Network stack, with slightly different requirements. The framework includes a mechanism to control this at each point. Support has been added for such points which are only present in upcoming CLs such as during packet forwarding and fragmentation. With this change, 'ping -R' and 'ping -T' work against gVisor and Fuchsia. $ ping -R 192.168.1.2 PING 192.168.1.2 (192.168.1.2) 56(124) bytes of data. 64 bytes from 192.168.1.2: icmp_seq=1 ttl=64 time=0.990 ms NOP RR: 192.168.1.1 192.168.1.2 192.168.1.1 $ ping -T tsprespec 192.168.1.2 192.168.1.1 192.168.1.2 PING 192.168.1.2 (192.168.1.2) 56(124) bytes of data. 64 bytes from 192.168.1.2: icmp_seq=1 ttl=64 time=1.20 ms TS: 192.168.1.2 71486821 absolute 192.168.1.1 746 Unit tests included for generic options, Timestamp options and Record Route options.

2020-10-27Wake up any waiters on an ICMP error on UDP socket.Bhasker Hariharan
This change wakes up any waiters when we receive an ICMP port unreachable control packet on an UDP socket as well as sets waiter.EventErr in the result returned by Readiness() when e.lastError is not nil. The latter is required where an epoll()/poll() is done after the error is already handled since we will never notify again in such cases. PiperOrigin-RevId: 339370469

2020-10-27Assign VFS2 overlay device numbers based on layer device numbers.Jamie Liu
In VFS1's overlayfs, files use the device and inode number of the lower layer inode if one exists, and the upper layer inode otherwise. The former behavior is inefficient (requiring lower layer lookups even if the file exists and is otherwise wholly determined by the upper layer), and somewhat dangerous if the lower layer is also observable (since both the overlay and lower layer file will have the same device and inode numbers and thus appear to be the same file, despite being behaviorally different). VFS2 overlayfs imitates Linux overlayfs (in its default configuration) instead; it always uses the inode number from the originating layer, but synthesizes a unique device number for directories and another device number for non-directory files that have not been copied-up. As it turns out, the latter is insufficient (in VFS2, and possibly Linux as well), because a given layer may include files with different device numbers. If two distinct files on such a layer have device number X and Y respectively, but share inode number Z, then the overlay will map both files to some private device number X' and inode number Z, potentially confusing applications. Fix this by assigning synthetic device numbers based on the lower layer's device number, rather than the lower layer's vfs.Filesystem. PiperOrigin-RevId: 339300341
