Removes package syserror and moves still relevant code to either linuxerr or to syserr (to be later removed). Internal errors are converted from random types to *errors.Error types used in linuxerr. Internal errors are in linuxerr/internal.go. PiperOrigin-RevId: 390724202

2021-06-29[syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and EINVALZach Koopmans
Remove three syserror entries duplicated in linuxerr. Because of the linuxerr.Equals method, this is a mere change of return values from syserror to linuxerr definitions. Done with only these three errnos as CLs removing all grow to a significantly large size. PiperOrigin-RevId: 382173835

2021-04-22Fix AF_UNIX listen() w/ zero backlog.Bhasker Hariharan
In https://github.com/google/gvisor/commit/f075522849fa a check to increase zero to a minimum backlog length was removed from sys_socket.go to bring it in parity with linux and then in tcp/endpoint.go we bump backlog by 1. But this broke calling listen on a AF_UNIX socket w/ a zero backlog as in linux it does allow 1 connection even with a zero backlog. This was caught by a php runtime test socket_abstract_path.phpt.

2021-04-05Fix listen backlog handling to be in parity with LinuxMithun Iyer
- Change the accept queue full condition for a listening endpoint to only honor completed (and delivered) connections. - Use syncookies if the number of incomplete connections is beyond listen backlog. This also cleans up the SynThreshold option code as that is no longer used with this change. - Added a new stack option to unconditionally generate syncookies. Similar to sysctl -w net.ipv4.tcp_syncookies=2 on Linux. - Enable keeping of incomplete connections beyond listen backlog. - Drop incoming SYNs only if the accept queue is filled up. - Drop incoming ACKs that complete handshakes when accept queue is full - Enable the stack to accept one more connection than programmed by listen backlog. - Handle backlog argument being zero, negative for listen, as Linux. - Add syscall and packetimpact tests to reflect the changes above. - Remove TCPConnectBacklog test which is polling for completed connections on the client side which is not reflective of whether the accept queue is filled up by the test. The modified syscall test in this CL addresses testing of connecting sockets. Fixes #3153 PiperOrigin-RevId: 366935921

2021-03-24Add POLLRDNORM/POLLWRNORM support.Bhasker Hariharan
On Linux these are meant to be equivalent to POLLIN/POLLOUT. Rather than hack these on in sys_poll etc it felt cleaner to just cleanup the call sites to notify for both events. This is what linux does as well. Fixes #5544 PiperOrigin-RevId: 364859977
