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. Fixes #6209 PiperOrigin-RevId: 382607638
2021-04-15Use nicer formatting for IP addresses in testsKevin Krakauer
This was semi-automated -- there are many addresses that were not replaced. Future commits should clean those up. Parse4 and Parse6 were given their own package because //pkg/test can introduce dependency cycles, as it depends transitively on //pkg/tcpip and some other netstack packages.

2021-03-11improve readability of ports packageKevin Krakauer
Lots of small changes: - simplify package API via Reservation type - rename some single-letter variable names that were hard to follow - rename some types PiperOrigin-RevId: 362442366
2021-01-28Change tcpip.Error to an interfaceTamir Duberstein
This makes it possible to add data to types that implement tcpip.Error. ErrBadLinkEndpoint is removed as it is unused. PiperOrigin-RevId: 354437314

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387
2019-12-09Add UDP SO_REUSEADDR support to the port manager.Ian Gudger
Next steps include adding support to the transport demuxer and the UDP endpoint. PiperOrigin-RevId: 284652151

2019-09-12Remove go_test from go_stateify and go_marshalMichael Pratt
They are no-ops, so the standard rule works fine. PiperOrigin-RevId: 268776264

2018-12-28Implement SO_REUSEPORT for TCP and UDP socketsAndrei Vagin
This option allows multiple sockets to be bound to the same port. Incoming packets are distributed to sockets using a hash based on source and destination addresses. This means that all packets from one sender will be received by the same server socket. PiperOrigin-RevId: 227153413 Change-Id: I59b6edda9c2209d5b8968671e9129adb675920cf
2018-10-23Track paths and provide a rename hook.Adin Scannell
This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

We have been unnecessarily creating too many savable types implicitly. PiperOrigin-RevId: 206334201 Change-Id: Idc5a3a14bfb7ee125c4f2bb2b1c53164e46f29a8
