2018-06-17Add rpcinet support for control messages.Brian Geffon
Add support for control messages, but at this time the only control message that the sentry will support here is SO_TIMESTAMP. PiperOrigin-RevId: 200922230 Change-Id: I63a852d9305255625d9df1d989bd46a66e93c446

2018-06-12Rpcinet doensn't handle SO_RCVTIMEO properly.Brian Geffon
Rpcinet already inherits socket.ReceiveTimeout; however, it's never set on setsockopt(2). The value is currently forwarded as an RPC and ignored as all sockets will be non-blocking on the RPC side. PiperOrigin-RevId: 200299260 Change-Id: I6c610ea22c808ff6420c63759dccfaeab17959dd
2018-06-11Rpcinet is incorrectly handling MSG_TRUNC with SOCK_STREAMBrian Geffon
SOCK_STREAM has special behavior with respect to MSG_TRUNC. Specifically, the data isn't actually copied back out to userspace when MSG_TRUNC is provided on a SOCK_STREAM. According to tcp(7): "Since version 2.4, Linux supports the use of MSG_TRUNC in the flags argument of recv(2) (and recvmsg(2)). This flag causes the received bytes of data to be discarded, rather than passed back in a caller-supplied buffer." PiperOrigin-RevId: 200134860 Change-Id: I70f17a5f60ffe7794c3f0cfafd131c069202e90d
2018-06-11rpcinet is treating EAGAIN and EWOULDBLOCK as different errnos.Brian Geffon

2018-06-08rpcinet is not correctly handling MSG_TRUNC on recvmsg(2).Brian Geffon
MSG_TRUNC can cause recvmsg(2) to return a value larger than the buffer size. In this situation it's an indication that the buffer was completely filled and that the msg was truncated. Previously in rpcinet we were returning the buffer size but we should actually be returning the payload length as returned by the syscall.

PiperOrigin-RevId: 199669120 Change-Id: I0be88cdbba29760f967e9a5bb4144ca62c1ed7aa
2018-06-06Add support for rpcinet ioctl(2).Brian Geffon
This change will add support for ioctls that have previously been supported by netstack. LINE_LENGTH_IGNORE PiperOrigin-RevId: 199544114 Change-Id: I3769202c19502c3b7d05e06ea9552acfd9255893
2018-06-05Add support for rpcinet owned procfs files.Brian Geffon
This change will add support for /proc/sys/net and /proc/net which will be managed and owned by rpcinet. This will allow these inodes to be forward as rpcs. PiperOrigin-RevId: 199370799 Change-Id: I2c876005d98fe55dd126145163bee5a645458ce4

2018-05-24rpcinet connect doesn't handle all errnos correctly.Brian Geffon
These were causing non-blocking related errnos to be returned to the sentry when they were created as blocking FDs internally. PiperOrigin-RevId: 197962932 Change-Id: I3f843535ff87ebf4cb5827e9f3d26abfb79461b0
