Minimum header sizes are already checked in each `case` arm below. Worse, the ICMP entries in transportProtocolMinSizes are incorrect, and produce false "raw packet" logs. PiperOrigin-RevId: 315730073

2020-06-09Fix write hang bug found by syzkaller.gVisor bot
After this change e.mu is only promoted to exclusively locked during route.Resolve. It downgrades back to read-lock afterwards. This prevents the second RLock() call gets stuck later in the stack. https://syzkaller.appspot.com/bug?id=065b893bd8d1d04a4e0a1d53c578537cde1efe99 Syzkaller logs does not contain interesting stack traces.

2020-06-09Handle removed NIC in NDP timer for packet txGhanan Gowripalan
NDP packets are sent periodically from NDP timers. These timers do not hold the NIC lock when sending packets as the packet write operation may take some time. While the lock is not held, the NIC may be removed by some other goroutine. This change handles that scenario gracefully.

2020-06-07netstack: parse incoming packet headers up-frontKevin Krakauer
Netstack has traditionally parsed headers on-demand as a packet moves up the stack. This is conceptually simple and convenient, but incompatible with iptables, where headers can be inspected and mangled before even a routing decision is made. This changes header parsing to happen early in the incoming packet path, as soon as the NIC gets the packet from a link endpoint. Even if an invalid packet is found (e.g. a TCP header of insufficient length), the packet is passed up the stack for proper stats bookkeeping. PiperOrigin-RevId: 315179302

2020-06-05Implement mount(2) and umount2(2) for VFS2.Rahat Mahmood
This is mostly syscall plumbing, VFS2 already implements the internals of mounts. In addition to the syscall defintions, the following mount-related mechanisms are updated: - Implement MS_NOATIME for VFS2, but only for tmpfs and goferfs. The other VFS2 filesystems don't implement node-level timestamps yet. - Implement the 'mode', 'uid' and 'gid' mount options for VFS2's tmpfs. - Plumb mount namespace ownership, which is necessary for checking appropriate capabilities during mount(2).
