If sys_prctl is called with PR_SET_MM without CAP_SYS_RESOURCE, the syscall should return failure with errno set to EPERM. See: http://man7.org/linux/man-pages/man2/prctl.2.html PiperOrigin-RevId: 224182874 Change-Id: I630d1dd44af8b444dd16e8e58a0764a0cf1ad9a3
2018-12-04Remove incorrect code and improve testing of Stack.GetMainNICAddressChris Kuiper

2018-12-04Fix mempolicy_test on bazel.Rahat Mahmood
Bazel runs multiple test cases on the same thread. Some of the test cases rely on the test thread starting with the default memory policy, while other tests modify the test thread's memory policy. This obviously breaks when the test framework doesn't run each test case on a new thread. Also fixing an incompatibility where set_mempolicy(2) was prevented from specifying an empty nodemask, which is allowed for some modes.

2018-11-27Fix data race in fs.Async.Nicolas Lacasse
Replaces the WaitGroup with a RWMutex. Calls to Async hold the mutex for reading, while AsyncBarrier takes the lock for writing. This ensures that all executing Async work finishes before AsyncBarrier returns. Also pushes the Async() call from Inode.Release into gofer/InodeOperations.Release(). This removes a recursive Async call which should not have been allowed in the first place. The gofer Release call is the slow one (since it may make RPCs to the gofer), so putting the Async call there makes sense.

2018-11-27Save shutdown flags first.Brian Geffon
With rpcinet if shutdown flags are not saved before making the rpc a race is possible where blocked threads are woken up before the flags have been persisted. This would mean that threads can block indefinitely in a recvmsg after a shutdown(SHUT_RD) has happened. PiperOrigin-RevId: 223089783 Change-Id: If595e7add12aece54bcdf668ab64c570910d061a

2018-11-20Use RET_KILL_PROCESS if available in kernelFabricio Voznika
RET_KILL_THREAD doesn't work well for Go because it will kill only the offending thread and leave the process hanging. RET_TRAP can be masked out and it's not guaranteed to kill the process. RET_KILL_PROCESS is available since 4.14. For older kernel, continue to use RET_TRAP as this is the best option (likely to kill process, easy to debug).

2018-11-20Use math.Rand to generate a random test container id.Nicolas Lacasse
We were relying on time.UnixNano, but that was causing collisions. Now we generate 20 bytes of entropy from rand.Read, and base32-encode it to get a valid container id. PiperOrigin-RevId: 222313867 Change-Id: Iaeea9b9582d36de55f9f02f55de6a5de3f739371

2018-11-15Allow sandbox.Wait to be called after the sandbox has exited.Nicolas Lacasse
sandbox.Wait is racey, as the sandbox may have exited before it is called, or even during. We already had code to handle the case that the sandbox exits during the Wait call, but we were not properly handling the case where the sandbox has exited before the call. The best we can do in such cases is return the sandbox exit code as the application exit code. PiperOrigin-RevId: 221702517 Change-Id: I290d0333cc094c7c1c3b4ce0f17f61a3e908d787

...to (remote, local), reflecting the (correct) names in the implementation of DeliverNetworkPacket (see tcpip/stack/nic.go). Also trim the names in DeliverNetworkPacket and elsewhere to avoid stuttering; since the type is tcpip.LinkAddress, there's no need to include "LinkAddr" in the parameter names. Note that every callsite passes arguments in the order (src, dst). PiperOrigin-RevId: 221514396 Change-Id: I3637454ad0d6e62a19e4dcbc2a16493798bd0f09
