2021-08-12Add support for TCP send buffer auto tuning.Nayana Bidari
Send buffer size in TCP indicates the amount of bytes available for the sender to transmit. This change will allow TCP to update the send buffer size when - TCP enters established state. - ACK is received. The auto tuning is disabled when the send buffer size is set with the SO_SNDBUF option. PiperOrigin-RevId: 390312274

2021-08-11[op] Make PacketBuffer Clone() do a deeper copy.Ayush Ranjan
Earlier PacketBuffer.Clone() would do a shallow top level copy of the packet buffer - which involved sharing the *buffer.Buffer between packets. Reading or writing to the buffer in one packet would impact the other. This caused modifications in one packet to affect the other's pkt.Views() which is not desired. Change the clone to do a deeper copy of the underlying buffer list and buffer pointers. The payload buffers (which are immutable) are still shared. This change makes the Clone() operation more expensive as we now need to allocate the entire buffer list. Added unit test to test integrity of packet data after cloning.

2021-08-11Do not clear merkle files when creating dentryChong Cai
The dentry for each file/directory can be created/destroyed multiple times during sandbox lifetime. We should not clear the Merkle file each time a dentry is created. PiperOrigin-RevId: 390277107

2021-08-11Popluate verity directory children namesChong Cai
We were relying on children adding its name to parent's dentry to populate parent's children list. However, this may not work since the parent dentry could be destroyed if its reference count drops to zero. In that case, a new dentry will be created when enabling the parent and it does not contain the children names info. Therefore we need to populate the child names list again to avoid missing children in the directory. PiperOrigin-RevId: 390270227

2021-08-11Initial cgroupfs support for subcontainersRahat Mahmood
Allow creation and management of subcontainers through cgroupfs directory syscalls. Also add a mechanism to specify a default root container to start new jobs in. This implements the filesystem support for subcontainers, but doesn't implement hierarchical resource accounting or task migration. PiperOrigin-RevId: 390254870

2021-08-09platform/kvm: fix a race condition in vCPU.unlock()Andrei Vagin
Right now, it contains the code: origState := atomic.LoadUint32(&c.state) atomicbitops.AndUint32(&c.state, ^vCPUUser) The problem here is that vCPU.bounce that is called from another thread can add vCPUWaiter when origState has been read but vCPUUser isn't cleared yet. In this case, vCPU.unlock doesn't notify other threads about changes and c.bounce will be stuck in the futex_wait call. PiperOrigin-RevId: 389697411

2021-08-05Bump gVisor build tags to go1.19Michael Pratt
Go's dev.typeparams branch already claims to be Go 1.18, so our !go1.18 build tags breaking testing gVisor with that branch. Normally I would not want to bump the build tags this early, but I plan to extend checklinkname to check the assumptions in these files and remove the build tags ASAP. So we just go ahead and bump the tags until then to unblock testing. PiperOrigin-RevId: 389037239

2021-08-04Reduce overhead of AlignedAtomic typesAndrei Vagin
AlignedAtomicUint64 is 15 bytes and it takes 16 bytes in structures. On 32-bit systems, variables and structure fields is guaranteed to be 32-bit aligned and this means that we need only 12 bytes to find 8 contiguous bytes.
