Netstack is supposed to be somewhat independent of the rest of gVisor, and
others should be able to use it without pulling in excessive dependencies.
Currently, there is no way to fight dependency creep besides careful code
review.
This change introduces a test rule `netstack_deps_check` that ensures the target
only relies on gVisor targets and a short allowlist of external dependencies.
Users who add a dependency will see an error and have to manually update the
allowlist.
The set of packages to test comes from //runsc, as it uses packages we would
expect users to commonly rely on. It was generated via:
$ find ./runsc -name BUILD | xargs grep tcpip | awk '{print $2}' | sort | uniq
(Note: We considered giving //pkg/tcpip it's own go.mod, but this breaks go
tooling.)

Fix a race where the ACK completing the handshake can be dropped by
a closing listener without RST to the peer. The listener close would
reset the accepted queue and that causes the connecting endpoint
in SYNRCVD state to drop the ACK thinking the queue if filled up.

It's a common pattern in test code to reinterpret_cast<sockaddr*> from
sockaddr_* structs. Make AsSockAddr() for them so code looks better.
Note: Why not a wrapper type for `sockaddr_storage` and etc?
It's also a common need to have a local in-out variable of socklen_t.
Creating a wrapper type may however lead to this wrong code:
Wrapper addr;
socklen_t addrlen = sizeof(addr);
where sizeof(Wrapper) may not equal to sizeof(sockaddr_storage).

Some FileDescriptions in verity fs were opened but DecRef() were missing
after used. This could result in a ref leak.

Use MarshalUnsafe for packed types as it is faster than MarshalBytes.

Holding this lock can cause the user's callback to deadlock if it

Some other cleanup while I'm here:
- Remove unused arguments
- Handle some unhandled errors
- Remove redundant casts
- Remove redundant parens
- Avoid shadowing `hash` package name

Use a linked list with cached length and capacity. The current channel
is already composed with a mutex and condition variable, and is never
used for its channel-like properties. Channels also require eager
allocation equal to their capacity, which a linked list does not.

The current SNAT implementation has several limitations:
- SNAT source port has to be specified. It is not optional.
- SNAT source port range is not supported.
- SNAT for UDP is a one-way translation. No response packets
are handled (because conntrack doesn't support UDP currently).
- SNAT and REDIRECT can't work on the same connection.

If the parent is not enabled in verity stepLocked(), failure to find
the child dentry could just mean an incorrect path.

Move maxListenBacklog check to the caller of endpoint Listen so that it
is applicable to Unix domain sockets as well.
This was changed in cl/366935921.

Both code paths perform this check; extract it and remove the comment

Set root dentry and root hash in verity fs before we verify the root
directory if a root hash is provided. These are used during
verification.

We should only set parent after child is verified. Also, if the parent
is set before verified, destroyLocked() will try to grab parent.dirMu,
which may cause deadlock.

Without this change, we ask the gofer server to update the permissions
whenever the UID, GID or size is updated via SetStat. Consequently, we don not
generate inotify events when the permissions actually change due to SGID bit
getting cleared.
With this change, we will update the permissions only when needed and generate
inotify events.

- Change the accept queue full condition for a listening endpoint
to only honor completed (and delivered) connections.
- Use syncookies if the number of incomplete connections is beyond
listen backlog. This also cleans up the SynThreshold option code
as that is no longer used with this change.
- Added a new stack option to unconditionally generate syncookies.
Similar to sysctl -w net.ipv4.tcp_syncookies=2 on Linux.
- Enable keeping of incomplete connections beyond listen backlog.
- Drop incoming SYNs only if the accept queue is filled up.
- Drop incoming ACKs that complete handshakes when accept queue is full
- Enable the stack to accept one more connection than programmed by
listen backlog.
- Handle backlog argument being zero, negative for listen, as Linux.
- Add syscall and packetimpact tests to reflect the changes above.
- Remove TCPConnectBacklog test which is polling for completed
connections on the client side which is not reflective of whether
the accept queue is filled up by the test. The modified syscall test
in this CL addresses testing of connecting sockets.

There's no reason to actually increment the semaphore, it just introduces the

Implement a new runsc command to set up a sandbox with verityfs and
run the measure tool. This is loosely forked from the do command, and
currently requires the caller to provide the measure tool binary.
