2020-01-26Unroll checksum computation loop.Bhasker Hariharan
Checksum computation is one of the most expensive bits of packet processing. Manual unrolling of the loop provides significant improvement in checksum speed.

2020-01-24Add anonymous device number allocation to VFS2.Jamie Liu
Note that in VFS2, filesystem device numbers are per-vfs.FilesystemImpl rather than global, avoiding the need for a "registry" type to handle save/restore. (This is more consistent with Linux anyway: compare e.g. mm/shmem.c:shmem_mount() => fs/super.c:mount_nodev() => (indirectly) set_anon_super().) PiperOrigin-RevId: 291425193

2020-01-24Increase timeouts for NDP tests' async eventsGhanan Gowripalan
Increase the timeout to 1s when waiting for async NDP events to help reduce flakiness. This will not significantly increase test times as the async events continue to receive an event on a channel. The increased timeout allows more time for an event to be sent on the channel as the previous timeout of 100ms caused some flakes. Test: Existing tests pass PiperOrigin-RevId: 291420936

2020-01-24Ignore external SIGURGMichael Pratt
Go 1.14+ sends SIGURG to Ms to attempt asynchronous preemption of a G. Since it can't guarantee that a SIGURG is only related to preemption, it continues to forward them to signal.Notify (see runtime.sighandler). We should ignore these signals, as applications shouldn't receive them. Note that this means that truly external SIGURG can no longer be sent to the application (as with SIGCHLD).

2020-01-23Fix master build case.Adin Scannell
Otherwise, this will be built when building a specific release tag (typically in the past), causing the master binary to be overwritten with something older. We can generally assume that tags will be applied after the commit has been integrated, and therefore that any builds pointing to tags will use only the tags. Another way to fix this would be to introduce something akin to the KOKORO_BUILD_NIGHTLY environment variable, but it doesn't seem strictly necessary. PiperOrigin-RevId: 291198171

2020-01-22Use embedded mutex pattern for stack.NICGhanan Gowripalan
- Wrap NIC's fields that should only be accessed while holding the mutex in an anonymous struct with the embedded mutex. - Make sure NIC's spoofing and promiscuous mode flags are only read while holding the NIC's mutex. - Use the correct endpoint when sending DAD messages. - Do not hold the NIC's lock when sending DAD messages. This change does not introduce any behaviour changes. Tests: Existing tests continue to pass. PiperOrigin-RevId: 291036251
