2019-12-10Add all upstream syscalls to tablesMichael Pratt
Package strace is missing some syscalls we actually implement (e.g., getrandom). We also see newer syscalls sometimes (e.g., membarrier) that would be handy to have formatted. Let's go ahead and add all syscalls in the latest upstream release (v5.4), even though we only intend to implement v4.4. None of them are implemented, just included as placeholders.

2019-12-03Support IP_TOS and IPV6_TCLASS socket options for hostinet sockets.Dean Deng
There are two potential ways of sending a TOS byte with outgoing packets: including a control message in sendmsg, or setting the IP_TOS/IPV6_TCLASS socket options (for IPV4 and IPV6 respectively). This change lets hostinet support the latter. Fixes #1188 PiperOrigin-RevId: 283550925

2019-11-26Allow open(O_TRUNC) and (f)truncate for proc files.Ian Lewis
This allows writable proc and devices files to be opened with O_CREAT|O_TRUNC. This is encountered most frequently when interacting with proc or devices files via the command line. e.g. $ echo 8192 1048576 4194304 > /proc/sys/net/ipv4/tcp_rmem Also adds a test to test the behavior of open(O_TRUNC), truncate, and ftruncate on named pipes.
