2019-04-23Revert runsc to use RecvMMsg packet dispatcher.Bhasker Hariharan
PacketMMap mode has issues due to a kernel bug. This change reverts us to using recvmmsg instead of a shared ring buffer to dispatch inbound packets. This will reduce performance but should be more stable under heavy load till PacketMMap is updated to use TPacketv3. See #210 for details. Perf difference between recvmmsg vs packetmmap.

2019-04-23Fixes to PacketMMap dispatcher.Bhasker Hariharan
This CL fixes the following bugs: - Uses atomic to set/read status instead of binary.LittleEndian.PutUint32 etc which are not atomic. - Increments ringOffsets for frames that are truncated (i.e status is tpStatusCopy) - Does not ignore frames with tpStatusLost bit set as they are valid frames and only indicate that there some frames were lost before this one and metrics can be retrieved with a getsockopt call. - Adds checks to make sure blockSize is a multiple of page size. This is required as the kernel allocates in pages per block and rejects sizes that are not page aligned with an EINVAL.

2019-04-23Remember file position during Readdir()Fabricio Voznika
The caller must call Readdir() at least twice to detect EOF. The old code was always restarting the directory search and then skipping elements already seen, effectively doubling the cost to read a directory.

2019-04-22Bugfix: fix fstatat symbol link to dirWei Zhang
For a symbol link to some directory, eg. `/tmp/symlink -> /tmp/dir` `fstatat("/tmp/symlink")` should return symbol link data, but `fstatat("/tmp/symlink/")` (symlink with trailing slash) should return directory data it points following linux behaviour. Currently fstatat() a symlink with trailing slash will get "not a directory" error which is wrong.

Break out the shutdown(2) with SHUT_RD syscall test into to two tests. The first tests that no packets are sent when shutting down the read side of a socket. The second tests that, after shutting down the read side of a socket, unread data can still be read, or an EOF if there is no more data to read.

2019-04-18netstack: use a proper network protocol to set gso.L3HdrLenAndrei Vagin
It is possible to create a listening socket which will accept IPv4 and IPv6 connections. In this case, we set IPv6ProtocolNumber for all accepted endpoints, even if they handle IPv4 connections. This means that we can't use endpoint.netProto to set gso.L3HdrLen. PiperOrigin-RevId: 244227948 Change-Id: I5e1863596cb9f3d216febacdb7dc75651882eef1
2019-04-17Don't allow sigtimedwait to catch unblockable signalsMichael Pratt
The existing logic attempting to do this is incorrect. Unary ^ has higher precedence than &^, so mask always has UnblockableSignals cleared, allowing dequeueSignalLocked to dequeue unblockable signals (which allows userspace to ignore them). Switch the logic so that unblockable signals are always masked. PiperOrigin-RevId: 244058487 Change-Id: Ib19630ac04068a1fbfb9dc4a8eab1ccbdb21edc3

2019-04-17Convert poll/select to operate more directly on linux.PollFDMichael Pratt
Current, doPoll copies the user struct pollfd array into a []syscalls.PollFD, which contains internal kdefs.FD and waiter.EventMask types. While these are currently binary-compatible with the Linux versions, we generally discourage copying directly to internal types (someone may inadvertantly change kdefs.FD to uint64). Instead, copy directly to a []linux.PollFD, which will certainly be binary compatible. Most of syscalls/polling.go is included directly into syscalls/linux/sys_poll.go, as it can then operate directly on linux.PollFD. The additional syscalls.PollFD type is providing little value. I've also added explicit conversion functions for waiter.EventMask, which creates the possibility of a different binary format.
