2020-01-22De-duplicate common test functionality for VFS2 filesystems.Rahat Mahmood
PiperOrigin-RevId: 291041576
2020-01-22Use embedded mutex pattern for stack.NICGhanan Gowripalan
- Wrap NIC's fields that should only be accessed while holding the mutex in an anonymous struct with the embedded mutex. - Make sure NIC's spoofing and promiscuous mode flags are only read while holding the NIC's mutex. - Use the correct endpoint when sending DAD messages. - Do not hold the NIC's lock when sending DAD messages. This change does not introduce any behaviour changes. Tests: Existing tests continue to pass. PiperOrigin-RevId: 291036251
2020-01-22Error marshalling the matcher.Kevin Krakauer
The iptables binary is looking for libxt_.so when it should be looking for libxt_udp.so, so it's having an issue reading the data in xt_match_entry. I think it may be an alignment issue. Trying to fix this is leading to me fighting with the metadata struct, so I'm gonna go kill that.

2020-01-21Rename DowngradableRWMutex to RWmutex.Ian Gudger
Also renames TMutex to Mutex. These custom mutexes aren't any worse than the standard library versions (same code), so having both seems redundant. PiperOrigin-RevId: 290873587

2020-01-18Include the cgroup name in the superblock options in /proc/self/mountinfo.Nicolas Lacasse
Java 11 parses /proc/self/mountinfo for cgroup information. Java 11.0.4 uses the mount path to determine what cgroups existed, but Java 11.0.5 reads the cgroup names from the superblock options. This CL adds the cgroup name to the superblock options if the filesystem type is "cgroup". Since gVisor doesn't actually support cgroups yet, we just infer the cgroup name from the path.
