2020-04-07Test TCP sender behavior against window shrinkinggVisor bot
RFC 1122 Section 3.7: A sending TCP MUST be robust against window shrinking, which may cause the "useable window" to become negative. PiperOrigin-RevId: 305377072

2020-04-07Make gofer.dentry.destroyLocked idempotentFabricio Voznika
gofer operations accumulate dentries touched in a slice to call checkCachingLocked on them when the operation is over. In case the same dentry is touched multiple times during the operation, checkCachingLocked, and consequently destroyLocked, may be called more than once for the same dentry.

2020-04-06Bump up acceptable sample count for flaky itimer test.Dean Deng
Running the test 1000x almost always produces 1+ test failures where the sample count is slightly more than 60. PiperOrigin-RevId: 305051754

2020-04-02Fix flaky TCPLinger2TimeoutAfterClose test.Bhasker Hariharan
The test is flaky in cooperative S/R mode because TCP timers are not restored across a S/R. This can cause the TCPLinger2 timer to not fire. This change disables S/R before setting the TCP_LINGER2 timeout. PiperOrigin-RevId: 304430536

2020-03-31Add socket filesystem and global disconnected socket mount for VFS2.Dean Deng
A socket mount where anonymous sockets will reside is added to the VirtualFilesystem. Socketfs is built on top of kernfs. Updates #1476, #1478, #1484, #1485. PiperOrigin-RevId: 304095251
2020-03-26Support owner matching for iptables.Nayana Bidari
This feature will match UID and GID of the packet creator, for locally generated packets. This match is only valid in the OUTPUT and POSTROUTING chains. Forwarded packets do not have any socket associated with them. Packets from kernel threads do have a socket, but usually no owner.

It's possible to execute the command that checks user's $HOME dir before the user is created. Move the code that creates the user inside exec so it can be serialized. PiperOrigin-RevId: 302986184
2020-03-25Misc fixes to make stat_test pass (almost)Fabricio Voznika
The only test failing now requires socket which is not available in VFS2 yet. Updates #1198 PiperOrigin-RevId: 302976572
2020-03-25Fix futex_benchmark.Jamie Liu
- Fix definitions of Futex* wrappers. - Correctly handle glibc syscall() (which returns -1 and sets errno instead of returning the raw syscall return value). - De-parameterize FutexWaitBitset, which was apparently intended to test with deadlines of between 0 and 100000 nanoseconds after the Unix epoch, but was broken due to the preceding two issues. - Use wall time to measure the durations of tests that are expected to block (and thus stop accumulating CPU time). - Require 5s for all tests to improve robustness in the presence of sentry GC. - Remove FutexContend and FutexContendDeadline; it's unclear what these are supposed to measure, given that (1) FutexLock is unrealistically inefficient and (2) the benchmark rewards slow scheduling (since this reduces contention).

2020-03-24Open a temp directory before changing capabilities and user ID-sAndrei Vagin
In cl/302130790, we started using a temp directory which is provided by bazel. By default, a test process has enough permissions to open it, but there is not any guarantee that it still will be able to do this after changing credentials. PiperOrigin-RevId: 302702337

2020-03-20test: Create a separate /tmp mount only for tests with the shared tagAndrei Vagin
The root mount is not shared by default, but all other mounts are shared. So if we create the /tmp mount, this means that we run tests on a shared mount even if tests run without the --shared option. PiperOrigin-RevId: 302130790

2020-03-12Kill sandbox process when parent process terminatesFabricio Voznika
When the sandbox runs in attached more, e.g. runsc do, runsc run, the sandbox lifetime is controlled by the parent process. This wasn't working in all cases because PR_GET_PDEATHSIG doesn't propagate through execve when the process changes uid/gid. So it was getting dropped when the sandbox execve's to change to user nobody. PiperOrigin-RevId: 300601247

Adds an oom_score_adj and oom_score proc file stub. oom_score_adj accepts writes of values -1000 to 1000 and persists the value with the task. New tasks inherit the parent's oom_score_adj. oom_score is a read-only stub that always returns the value '0'. Issue #202 PiperOrigin-RevId: 299245355
