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

2018-11-14Rename incorrectly named (dst, src) arguments in DeliverNetworkPacket prototypeBert Muthalaly
...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

Previously, TCP_NODELAY was always enabled and we would lie about it being configurable.

2018-11-08Implement sync_file_range()Andrei Vagin
sync_file_range - sync a file segment with disk In Linux, sync_file_range() accepts three flags: SYNC_FILE_RANGE_WAIT_BEFORE Wait upon write-out of all pages in the specified range that have already been submitted to the device driver for write-out before performing any write. SYNC_FILE_RANGE_WRITE Initiate write-out of all dirty pages in the specified range which are not presently submitted write-out. Note that even this may block if you attempt to write more than request queue size. SYNC_FILE_RANGE_WAIT_AFTER Wait upon write-out of all pages in the range after performing any write. In this implementation: SYNC_FILE_RANGE_WAIT_BEFORE without SYNC_FILE_RANGE_WAIT_AFTER isn't supported right now. SYNC_FILE_RANGE_WRITE is skipped. It should initiate write-out of all dirty pages, but it doesn't wait, so it should be safe to do nothing while nobody uses SYNC_FILE_RANGE_WAIT_BEFORE. SYNC_FILE_RANGE_WAIT_AFTER is equal to fdatasync(). In Linux, sync_file_range() doesn't writes out the file's meta-data, but fdatasync() does if a file size is changed.

2018-11-07AsyncBarrier should be run after all defers in destroyContainerFS.Nicolas Lacasse
destroyContainerFS must wait for all async operations to finish before returning. In an attempt to do this, we call fs.AsyncBarrier() at the end of the function. However, there are many defer'd DecRefs which end up running AFTER the AsyncBarrier() call. This CL fixes this by calling fs.AsyncBarrier() in the first defer statement, thus ensuring that it runs at the end of the function, after all other defers.

2018-11-05Fix race between start and destroyFabricio Voznika
Before this change, a container starting up could race with destroy (aka delete) and leave processes behind. Now, whenever a container is created, Loader.processes gets a new entry. Start now expects the entry to be there, and if it's not it means that the container was deleted. I've also fixed Loader.waitPID to search for the process using the init process's PID namespace. We could use a few more tests for signal and wait. I'll send them in another cl. PiperOrigin-RevId: 220224290 Change-Id: I15146079f69904dc07d43c3b66cc343a2dab4cc4

2018-11-01Prevent premature destruction of shm segments.Rahat Mahmood
Shm segments can be marked for lazy destruction via shmctl(IPC_RMID), which destroys a segment once it is no longer attached to any processes. We were unconditionally decrementing the segment refcount on shmctl(IPC_RMID) which allowed a user to force a segment to be destroyed by repeatedly calling shmctl(IPC_RMID), with outstanding memory maps to the segment. This is problematic because the memory released by a segment destroyed this way can be reused by a different process while remaining accessible by the process with outstanding maps to the segment.
