2020-03-25Remove TODO to push down exec permission checkFabricio Voznika
Pushing it down requires all implementation to check for exec individualy which is not maintanable. Making it part of GenericCheckPermissions add extra cost to everyone that calls it. So it's better to keep is in VirtualFilesystem.OpenAt. Updates #1193 PiperOrigin-RevId: 302982993

2020-03-25travis: exclude copybara branchesAndrei Vagin
When copybara migrates changes, it creates a new branch and then creates a pull-requests which is based on this branch. In this case, travis-ci triggers build twice for the branch and for the pull-request. PiperOrigin-RevId: 302930634

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
