2020-04-08Handle utimes correctly for shared gofer filesystems.Dean Deng
Determine system time from within the sentry rather than relying on the remote filesystem to prevent inconsistencies. Resolve related TODOs; the time discrepancies in question don't exist anymore. PiperOrigin-RevId: 305557099

PiperOrigin-RevId: 305328184
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. Updates #1198 PiperOrigin-RevId: 305276819
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

2020-03-25Misc 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
2020-03-24Open 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

2020-03-14Plumb VFS2 imported fds into virtual filesystem.Dean Deng
- When setting up the virtual filesystem, mount a host.filesystem to contain all files that need to be imported. - Make read/preadv syscalls to the host in cases where preadv2 may not be supported yet (likewise for writing). - Make save/restore functions in kernel/kernel.go return early if vfs2 is enabled.

2020-03-05Stub oom_score_adj and oom_score.Ian Lewis
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

PiperOrigin-RevId: 296526279
2020-02-20Initial network namespace support.gVisor bot
TCP/IP will work with netstack networking. hostinet doesn't work, and sockets will have the same behavior as it is now. Before the userspace is able to create device, the default loopback device can be used to test. /proc/net and /sys/net will still be connected to the root network stack; this is the same behavior now.
