Earlier we were docker exec-ing each test at a time. However invoking the test
framework has a fixed overhead which made it infeasible to make the runtime
tests run as presubmits. This change now executes tests in batches of 50 (can
be altered). This really speeds up testing process.
With this change, the following tests can be run in reasonable times:
- Go
- Nodejs
- Php
- Python

RFC-1122 (and others) specify that UDP should not receive
datagrams that have a source address that is a multicast address.
Packets should never be received FROM a multicast address.
See also, RFC 768: 'User Datagram Protocol'
J. Postel, ISI, 28 August 1980
A UDP datagram received with an invalid IP source address
(e.g., a broadcast or multicast address) must be discarded
by UDP or by the IP layer (see rfc 1122 Section 3.2.1.3).
This CL does not address TCP or broadcast which is more complicated.
Also adds a test for both ipv6 and ipv4 UDP.

Adds a netns flag to runsc spec that allows users to specify a network
namespace path when creating a sample config.json file. Also, adds the ability
to specify the command arguments used when running the container.
This will make it easier for new users to create sample OCI bundles without
having to edit the config.json by hand.

Enabling IPv6 in Docker caused IPv4 tests to fail because localAddrs
didn't distinguish between address types. Example failure:

Moves following to new dockerutil API:

Fixed an issue with the runtime test runner which enables us to run tests in
shards. We had to touch the status file as indicated by an env var.

- Only use MAXSYMLINKS/2+1 symlinks for each of the interpreter and script
paths in SymlinkLimitRefreshedForInterpreter to tolerate cases where the
original paths (/tmp, /bin, or /bin/echo) themselves contain symlinks.
- Ensure that UnshareFiles performs execve immediately after clone(CLONE_VFORK)
(no heap allocation for ExecveArray/RunfilesPath).
- Use lstat() rather than stat() for the existence check in fs_util's Exists;
the latter will fail if the symlink target does not exist, even if the
symlink does.

RFC 6864 imposes various restrictions on the uniqueness of the IPv4
Identification field for non-atomic datagrams, defined as an IP datagram that
either can be fragmented (DF=0) or is already a fragment (MF=1 or positive
fragment offset). In order to be compliant, the ID field is assigned for all
non-atomic datagrams.
Add a TCP unit test that induces retransmissions and checks that the IPv4
ID field is unique every time. Add basic handling of the IP_MTU_DISCOVER
socket option so that the option can be used to disable PMTU discovery,
effectively setting DF=0. Attempting to set the sockopt to anything other
than disabled will fail because PMTU discovery is currently not implemented,
and the default behavior matches that of disabled.

The current convention is when a header is set to pkt.XxxHeader field, it
gets removed from pkt.Data. ICMP does not currently follow this convention.

This change fixes a few things:
- creating sockets using mknod(2) is supported via vfs2
- fsgofer can create regular files via mknod(2)
- mode = 0 for mknod(2) will be interpreted as regular file in vfs2 as well

The fdnotifier package provides an API to a thread that continually epolls
arbitrary host FDs. The set of events polled for each host FD is (intended to
be) all events for which a waiter.Entry has expressed interest, as returned by
waiter.Queue.Events() for the waiter.Queue registered to the given host FD.
When the set of events changes (due to a change in the set of registered
waiter.Entries), the mutator must call fdnotifier.UpdateFD() to recalculate the
new event set and propagate it to the epoll FD.

Avoid a race where an arbitrary goroutine scheduling delay can cause the
processor to miss events and hang indefinitely.
Reduce allocations by storing processors by-value in the dispatcher, and
by using a single WaitGroup rather than one per processor.

Before this change, running packetimpact tests produces:
parameter 'direct' must contain a list of elements, and may no longer
accept a depset. The deprecated behavior may be temporarily re-enabled
by setting --incompatible_disable_depset_inputs=false
The positional parameter to depset has been changed to mean `direct`
rather than its previous meaning of `items`. The documentation[0]
explains:
A positional parameter distinct from other parameters for legacy
support.
If --incompatible_disable_depset_items is false, this parameter
serves as the value of items.
If --incompatible_disable_depset_items is true, this parameter
serves as the value of direct.
See the documentation for these parameters for more details.

We do not support RWF_SYNC/RWF_DSYNC and probably shouldn't silently accept
them, since the user may incorrectly believe that we are synchronizing I/O.
Remove the pwritev2 test verifying that we support these flags.
gvisor.dev/issue/2601 is the tracking bug for deciding which RWF_.* flags
we need and supporting them.

Currently, we always perform a full-file sync which could be extremely
expensive for some applications. Although vfs1 did not fully support
sync_file_range, there were some optimizations that allowed us skip some
unnecessary write-outs.

After we change credentials, it is possible that we no longer have access to
the sticky directory where we are trying to delete files. Use an open fd so
this is not an issue.
