GO's runtime calls the write system call twice to print "panic:"
and "the reason of this panic", so here is a race window when
other threads can print something to the log and we will see
something like this:
panic: log messages from another thread
The reason of the panic.
This confuses the syzkaller blacklist and dedup detection.
It also makes the logs generally difficult to read. e.g.,
data races often have one side of the race, followed by
a large "diagnosis" dump, finally followed by the other
side of the race.

pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2.
mount and umount2 aren't ported out of temporary laziness. access and faccessat
need additional FSImpl methods to implement properly, but are stubbed to
prevent googletest from CHECK-failing. Other syscalls require additional
plumbing.

TestMultiContainerKillAll timed out under --race. Without logging,
we cannot tell if the process list is still increasing, but slowly,
or is stuck.

TCP/IP will work with netstack networking. hostinet doesn't work, and sockets
will have the same behavior as it is now.
Before the userspace is able to create device, the default loopback device can
be used to test.
/proc/net and /sys/net will still be connected to the root network stack; this
is the same behavior now.

This is to fix a data race between sending an external signal to
a ThreadGroup and kernel saving state for S/R.

- Added fsbridge package with interface that can be used to open
and read from VFS1 and VFS2 files.
- Converted ELF loader to use fsbridge
- Added VFS2 types to FSContext
- Added vfs.MountNamespace to ThreadGroup

Note that these are only implemented for tmpfs, and other impls will still
return EOPNOTSUPP.

Sometimes we get this error under TSAN:
"""
error getting process data from container: connecting to control server at PID
XXXX: connection refused
"""
The theory is that the top "sleep 20" was too short for TSAN, and the container
already exited, so we get connected refused. This commit changes the test to
let container signaling it's running by touching a file repeatedly forever
during the test.

The host /etc can contain config files which affect tests.
For example, bash reads /etc/passwd and if it is too big
a test can fail by timeout.

container_test was flaking because a small percentage of runs timed out. Tested
this fix with --runs_per_test=100.

Go 1.14 has a workaround for a Linux 5.2-5.4 bug which requires mlock'ing the g
stack to prevent register corruption. We need to allow this syscall until it is
removed from Go.

* Tests are picked for a shard differently. It now picks one test from each
block, instead of picking the whole block. This makes the same kind of tests
spreads across different shards.
* Reduce the number of connect() calls in TCPListenClose.

FD table now holds both VFS1 and VFS2 types and uses the correct
one based on what's set.
Parts of this CL are just initial changes (e.g. sys_read.go,
runsc/main.go) to serve as a template for the remaining changes.

In general, we've learned that logging must be avoided at all
costs in the hot path. It's unlikely that the optimizations
here were significant in any case, since buffer would certainly
escape.
This also adds a test to ensure that the caller identification
works as expected, and so that logging can be benchmarked.

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

There was a very bare get/setxattr in the InodeOperations interface. Add
context.Context to both, size to getxattr, and flags to setxattr.
Note that extended attributes are passed around as strings in this
implementation, so size is automatically encoded into the value. Size is
added in getxattr so that implementations can return ERANGE if a value is larger
than can fit in the user-allocated buffer. This prevents us from unnecessarily
passing around an arbitrarily large xattr when the user buffer is actually too
small.
Don't use the existing xattrwalk and xattrcreate messages and define our
own, mainly for the sake of simplicity.
Extended attributes will be implemented in future commits.

* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.
This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

Remove introduced CPUNumMin config and hard-code it as 2.
|
|
* Add `--cpu-num-min` flag to control minimum CPUs
* Only lower CPU count
* Fix comments
|
|
When application is not cgroups-aware, it can spawn excessive threads
which often defaults to CPU number.
Introduce a opt-in flag that will set CPU number accordingly to CPU
quota (if available).

It would be preferrable to test iptables via syscall tests, but there are some
problems with that approach:
* We're limited to loopback-only, as syscall tests involve only a single
container. Other link interfaces (e.g. fdbased) should be tested.
* We'd have to shell out to call iptables anyways, as the iptables syscall
interface itself is too large and complex to work with alone.
* Running the Linux/native version of the syscall test will require root, which
is a pain to configure, is inherently unsafe, and could leave host iptables
misconfigured.
Using the go_test target allows there to be no new test runner.

runsc debug --ps list all processes with all threads. This option is added to
the debug command but not to the ps command, because it is going to be used for
debug purposes and we want to add any useful information without thinking about
backward compatibility.
This will help to investigate syzkaller issues.

When the sandbox is destroyed, making URPC calls to destroy the
container will fail. The code was checking if the sandbox was
running before attempting to make the URPC call, but that is racy.

There are two potential ways of sending a TOS byte with outgoing packets:
including a control message in sendmsg, or setting the IP_TOS/IPV6_TCLASS
socket options (for IPV4 and IPV6 respectively). This change lets hostinet
support the latter.
