2021-10-26Simplify vfs.NewDisconnectedMount signature and callpoints.Ayush Ranjan
vfs.NewDisconnectedMount has no error paths. Its much prettier without the error return value. Also simplify MountDisconnected which would immediately drop the refs taken by NewDisconnectedMount. Instead make it directly call newMount. PiperOrigin-RevId: 405767966

2021-10-14Report total memory based on limit or hostFabricio Voznika
gVisor was previously reporting the lower of cgroup limit or 2GB as total memory. This may cause applications to make bad decisions based on amount of memory available to them when more than 2GB is required. This change makes the lower of cgroup limit or the host total memory to be reported inside the sandbox. This also is more inline with docker which always reports host total memory. Note that reporting cgroup limit is strictly better than host total memory when there is a limit set. Fixes #5608 PiperOrigin-RevId: 403241608

Go 1.18 (as of golang.org/cl/324129) uses per-thread timers created and set with timer_create/timer_settime for more accurate CPU pprof profiling. Add these syscalls to the allowed syscall filters. PiperOrigin-RevId: 399941561

2021-09-20[lisa] Plumb lisafs through runsc.Ayush Ranjan
lisafs is only supported in VFS2. Added a runsc flag which enables lisafs. When the flag is enabled, the gofer process and the client communicate using lisafs protocol instead of 9P. Added a filesystem option in fsimpl/gofer which indicates if lisafs is being used. That will be used to gate lisafs on the gofer client. Note that this change does not make the gofer client use lisafs just yet. Updates #5465 PiperOrigin-RevId: 397917844

2021-09-16runsc: add global profile collection flagsMichael Pratt
Add global flags -profile-{block,cpu,heap,mutex} and -trace which enable collection of the specified profile for the entire duration of a container execution. This provides a way to definitively start profiling before that application starts, rather than attempting to race with an out-of-band `runsc debug`. Note that only the main boot process is profiled. This exposed a bug in Task.traceExecEvent: a crash when tracing and -race are enabled. traceExecEvent is called off of the task goroutine, but uses the Task as a context, which is a violation of the Task contract. Switching to the AsyncContext fixes the issue. Fixes #220

2021-09-15Pass address properties in a single structTony Gong
Replaced the current AddAddressWithOptions method with AddAddressWithProperties which passes all address properties in a single AddressProperties type. More properties that need to be configured in the future are expected, so adding a type makes adding them easier. PiperOrigin-RevId: 396930729

2021-09-09Remove link/packetsocketGhanan Gowripalan
This change removes NetworkDispatcher.DeliverOutboundPacket. Since all packet writes go through the NIC (the only NetworkDispatcher), we can deliver outgoing packets to interested packet endpoints before writing the packet to the link endpoint as the stack expects that all packets that get delivered to a link endpoint are transmitted on the wire. That is, link endpoints no longer need to let the stack know when it writes a packet as the stack already knows about the packet it writes through a link endpoint. PiperOrigin-RevId: 395761629

2021-09-01Support sending with packet socketsGhanan Gowripalan
...through the loopback interface, only. This change only supports sending on packet sockets through the loopback interface as the loopback interface is the only interface used in packet socket syscall tests - the other link endpoints are not excercised with the existing test infrastructure. Support for sending on packet sockets through the other interfaces will be added as needed. BUG: https://fxbug.dev/81592 PiperOrigin-RevId: 394368899

2021-08-19Add loopback interface as an ethernet-based deviceGhanan Gowripalan
...to match Linux behaviour. We can see evidence of Linux representing loopback as an ethernet-based device below: ``` # EUI-48 based MAC addresses. $ ip link show lo 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 # tcpdump showing ethernet frames when sniffing loopback and logging the # link-type as EN10MB (Ethernet). $ sudo tcpdump -i lo -e -c 2 -n tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on lo, link-type EN10MB (Ethernet), snapshot length 262144 bytes 03:09:05.002034 00:00:00:00:00:00 > 00:00:00:00:00:00, ethertype IPv4 (0x0800), length 66: 127.0.0.1.9557 > 127.0.0.1.36828: Flags [.], ack 3562800815, win 15342, options [nop,nop,TS val 843174495 ecr 843159493], length 0 03:09:05.002094 00:00:00:00:00:00 > 00:00:00:00:00:00, ethertype IPv4 (0x0800), length 66: 127.0.0.1.36828 > 127.0.0.1.9557: Flags [.], ack 1, win 6160, options [nop,nop,TS val 843174496 ecr 843159493], length 0 2 packets captured 116 packets received by filter 0 packets dropped by kernel ``` Wireshark shows a similar result as the tcpdump example above.
