2021-07-01Fix bug with TCP bind w/ SO_REUSEADDR.Bhasker Hariharan
In gVisor today its possible that when trying to bind a TCP socket w/ SO_REUSEADDR specified and requesting the kernel pick a port by setting port to zero can result in a previously bound port being returned. This behaviour is incorrect as the user is clearly requesting a free port. The behaviour is fine when the user explicity specifies a port. This change now checks if the user specified a port when making a port reservation for a TCP port and only returns unbound ports even if SO_REUSEADDR was specified.

2021-06-29Sort children map before hashChong Cai
The unordered map may generate different hash due to its order. The children map needs to be sorted each time before hashing to avoid false verification failure due to the map. Store the sorted children map in verity dentry to avoid sorting it each time verification happens. Also serialize the whole VerityDescriptor struct to hash now that the map is removed from it.

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

2021-06-25Remove sndQueue as its pointless now.Bhasker Hariharan
sndQueue made sense when the worker goroutine and the syscall context held different locks. Now both lock the endpoint lock before doing anything which means adding to sndQueue is pointless as we move it to writeList immediately after that in endpoint.Write() by calling e.drainSendQueue.

This change prepares for a later change which supports the NDP Route Information option to discover more-specific routes, as per RFC 4191.
