2020-12-23vfs1: don't allow to open socket filesAndrei Vagin
open() has to return ENXIO in this case. O_PATH isn't supported by vfs1. PiperOrigin-RevId: 348820478

2020-09-11Fix host unix socket to not swallow EOF incorrectly.Bhasker Hariharan
Fixes an error where in case of a receive buffer larger than the host send buffer size for a host backed unix dgram socket we would end up swallowing EOF from recvmsg syscall causing the read() to block forever. PiperOrigin-RevId: 331192810

2020-07-15fdbased: Vectorized write for packet; relax writev syscall filter.Ting-Yu Wang
Now it calls pkt.Data.ToView() when writing the packet. This may require copying when the packet is large, which puts the worse case in an even worse situation. This sent out in a separate preparation change as it requires syscall filter changes. This change will be followed by the change for the adoption of the new PacketHeader API.

2020-06-10Deleting the maxSendBufferSize from fs/hostBin Lu
When I do high-performance networking, the value of wmem_max is often set very high, specially for 10/25/50 Gigabit NIC. I think maybe this restriction is not suitable. Signed-off-by: Bin Lu <bin.lu@arm.com>

2020-04-27Import host sockets.Dean Deng

2020-03-26Use host-defined file owner and mode, when possible, for imported fds.Dean Deng
Using the host-defined file owner matches VFS1. It is more correct to use the host-defined mode, since the cached value may become out of date. However, kernfs.Inode.Mode() does not return an error--other filesystems on kernfs are in-memory so retrieving mode should not fail. Therefore, if the host syscall fails, we rely on a cached value instead. Updates #1672. PiperOrigin-RevId: 303220864

2020-03-18Port imported TTY fds to vfs2.Dean Deng
Refactor fs/host.TTYFileOperations so that the relevant functionality can be shared with VFS2 (fsimpl/host.ttyFD). Incorporate host.defaultFileFD into the default host.fileDescription. This way, there is no need for a separate default_file.go. As in vfs1, the TTY file implementation can be built on top of this default and override operations as necessary (PRead/Read/PWrite/Write, Release, Ioctl). Note that these changes still need to be plumbed into runsc, which refers to imported TTYs in control/proc.go:ExecAsync. Updates #1672. PiperOrigin-RevId: 301718157

2020-03-14Plumb VFS2 imported fds into virtual filesystem.Dean Deng
- When setting up the virtual filesystem, mount a host.filesystem to contain all files that need to be imported. - Make read/preadv syscalls to the host in cases where preadv2 may not be supported yet (likewise for writing). - Make save/restore functions in kernel/kernel.go return early if vfs2 is enabled.
