2020-06-05iptables: loopback traffic skips prerouting chainKevin Krakauer
Loopback traffic is not affected by rules in the PREROUTING chain. This change is also necessary for istio's envoy to talk to other components in the same pod.
2020-06-05Use top-down allocation for pgalloc.Adin Scannell
This change has multiple small components. First, the chunk size is bumped to 1GB in order to avoid creating excessive VMAs in the Sentry, which can lead to VMA exhaustion (and hitting limits). Second, gap-tracking is added to the usage set in order to efficiently scan for available regions. Third, reclaim is moved to a simple segment set. This is done to allow the order of reclaim to align with the Allocate order (which becomes much more complex when trying to track a "max page" as opposed to "min page", so we just track explicit segments instead, which should make reclaim scanning faster anyways). Finally, the findAvailable function attempts to scan from the top-down, in order to maximize opportunities for VMA merging in applications (hopefully preventing the same VMA exhaustion that can affect the Sentry).

2020-06-05Unshare files on execAndrei Vagin
The current task can share its fdtable with a few other tasks, but after exec, this should be a completely separate process. PiperOrigin-RevId: 314999565
2020-06-05Fix error code returned due to Port exhaustion.Bhasker Hariharan
For TCP sockets gVisor incorrectly returns EAGAIN when no ephemeral ports are available to bind during a connect. Linux returns EADDRNOTAVAIL. This change fixes gVisor to return the correct code and adds a test for the same. This change also fixes a minor bug for ping sockets where connect() would fail with EINVAL unless the socket was bound first. Also added tests for testing UDP Port exhaustion and Ping socket port exhaustion. PiperOrigin-RevId: 314988525

2020-06-05Handle TCP segment split cases as per MSS.Mithun Iyer
- Always split segments larger than MSS. Currently, we base the segment split decision as a function of the send congestion window and MSS, which could be greater than the MSS advertised by remote. - While splitting segments, ensure the PSH flag is reset when there are segments that are queued to be sent. - With TCP_CORK, hold up segments up until MSS. Fix a bug in computing available send space before attempting to coalesce segments. Fixes #2832 PiperOrigin-RevId: 314802928
2020-06-04test/syscall: run hostnet tests in separate network namespacesAndrei Vagin
A few tests use hard coded port numbers, so we need to guruantee that these ports will not be used for somthing else.
2020-06-03Add test for O_TRUNCZach Koopmans
b/36576592 calls out an edge case previously not supported by HostFS. HostFS is currently being removed, meaning gVisor supports this feature. Simply add the test to open_test. PiperOrigin-RevId: 314610226
2020-06-03Avoid TCP segment split when out of sender window.Mithun Iyer
If the entire segment cannot be accommodated in the receiver advertised window and if there are still unacknowledged pending segments, skip splitting the segment. The segment transmit would get retried by the retransmit handler. PiperOrigin-RevId: 314538523

2020-05-29Move TCP to CLOSED from SYN-RCVD on RST.Mithun Iyer
RST handling is broken when the TCP state transitions from SYN-SENT to SYN-RCVD in case of simultaneous open. An incoming RST should trigger cleanup of the endpoint. RFC793, section 3.9, page 70. Fixes #2814 PiperOrigin-RevId: 313828777

2020-05-29Port inotify to vfs2, with support in tmpfs.Dean Deng
Support in other filesystem impls is still needed. Unlike in Linux and vfs1, we need to plumb inotify down to each filesystem implementation in order to keep track of links/inode structures properly. IN_EXCL_UNLINK still needs to be implemented, as well as a few inotify hooks that are not present in either vfs1 or vfs2. Those will be addressed in subsequent changes. Updates #1479.

VFS2 is adding more functionality than VFS1. In order to test new functionality, it's required to skip some tests with VFS1. To skip tests, use: SKIP_IF(IsRunningWithVFS1()); The test will run in Linux and gVisor with VFS2 enabled. Updates #1035 PiperOrigin-RevId: 312698616

2020-05-19Fix flaky udp tests by polling before reading.Dean Deng
On native Linux, calling recv/read right after send/write sometimes returns EWOULDBLOCK, if the data has not made it to the receiving socket (even though the endpoints are on the same host). Poll before reading to avoid this. Making this change also uncovered a hostinet bug (gvisor.dev/issue/2726), which is noted in this CL. PiperOrigin-RevId: 312320587

2020-05-13Fix TCP segment retransmit timeout handling.Mithun Iyer
As per RFC 1122 and Linux retransmit timeout handling: - The segment retransmit timeout needs to exponentially increase and cap at a predefined value. - TCP connection needs to timeout after a predefined number of segment retransmissions. - TCP connection should not timeout when the retranmission timeout exceeds MaxRTO, predefined upper bound.

Actual honoring of these options will be added as required. Fixes #2626, #2625 PiperOrigin-RevId: 311453777
