TCP, in CLOSING state, MUST send an ACK with next expected SEQ number after
receiving any segment with OTW SEQ number and remain in the same state.
While I am here, I also changed shutdown to behave the same as other calls
in posix_server.

The test queries for RTO via TCP_INFO and applies that to the
rest of the test. The RTO is estimated by processing incoming ACK.
There is a race in the test where we may query for RTO before the
incoming ACK was processed. Fix the race in the test by letting the
DUT complete a payload receive, thus estimating RTO before proceeding
to query the RTO. Bump up the time correction to reduce flakes.

The run-benchmark target would run the benchmark with VFS1.

By default net.ipv4.ping_group_range is set to "1 0" and no one (even the root)
can create an ICMP socket. Setting it to "0 0" allows root, which we are inside
the container, to create ICMP sockets for packetimpact tests.

We can generate more than one apt repo for the same package. If we will
sign a package again, its file will be changed and all hashes that have
been generated before will be invalid.

With /proc/sys/net/ipv4/ip_local_port_range implemented, the socket stress
test runs in a more normal time and doesn't need to sacrifice coverage to
prevent timeouts.

Lots of small changes:
- simplify package API via Reservation type
- rename some single-letter variable names that were hard to follow
- rename some types

By default, fusefs defers node permission checks to the server. The
default_permissions mount option enables the usual unix permission
checks based on the node owner and mode bits. Previously fusefs was
incorrectly checking permissions unconditionally.
Additionally, fusefs should restrict filesystem access to processes
started by the mount owner to prevent the fuse daemon from gaining
priviledge over other processes. The allow_other mount option
overrides this behaviour. Previously fusefs was incorrectly skipping
this check.
Updates #3229

This binary is used to recursively enable and generate Merkle tree files
for all files and directories in a file system from inside a gVisor
sandbox.

The Merkle tree files need to be cleared before enabling to avoid
redundant content.

The previous "bind" filesystem, already included in go/runsc-benchmarks
is a remote re-validate mount. However, the non-re-validate mount
was not present, and it has been added in the form of rootfs.
Also, fix the fio runs to reads/writes of 10GB as running
with --test.benchtime=Xs may scale beyond the memory available
to tmpfs mounts on buildkite VMs. Currently, our buildkite
pipelines are run on e2-standard-8 machines with 32GB of memory,
allowing tmpfs mounts to safely be at least 10GB.

👋 hello there! I'm a fellow Googler who works on projects that leverage GitHub Actions for CI/CD. Recently I noticed a large increase in our queue time, and I've tracked it down to the [limit of 180 concurrent jobs](https://docs.github.com/en/actions/reference/usage-limits-billing-and-administration) for an organization. To help be better citizens, I'm proposing changes across a few repositories that will reduce GitHub Actions hours and consumption. I hope these changes are reasonable and I'm happy to talk through them in more detail.
- (**you were already doing this, thank you!**) Only run GitHub Actions for pushes and PRs against the main branch of the repository. If your team uses a forking model, this change will not affect you. If your team pushes branches to the repository directly, this changes actions to only run against the primary branches or if you open a Pull Request against a primary branch.
- For long-running jobs (especially tests), I added the "Cancel previous" workflow. This is very helpful to prevent a large queue backlog when you are doing rapid development and pushing multiple commits. Without this, GitHub Actions' default behavior is to run all actions on all commits.
There are other changes you could make, depending on your project (but I'm not an expert):
- If you have tests that should only run when a subset of code changes, consider gating your workflow to particular file paths. For example, we have some jobs that do Terraform linting, but [they only run when Terraform files are changed](https://github.com/google/exposure-notifications-verification-server/blob/c4f59fee71042cf668747e599e7c769fca736554/.github/workflows/terraform.yml#L3-L11).
Hopefully these changes are not too controversial and also hopefully you can see how this would reduce actions consumption to be good citizens to fellow Googlers. If you have any questions, feel free to respond here or ping me on chat. Thank you!

- Implement Stringer for it so that we can improve error messages.
- Use TCPFlags through the code base. There used to be a mixed usage of byte,
uint8 and int as TCP flags.

Thread from earlier test can show up in `/proc/self/tasks` while the
thread tears down. Account for that when searching for procs for the
first time in the test.

The dynamic type user defines the marshalling logic, so we don't need to test
for things like alignment, absence of slices, etc.
For dynamic types, the go_marshal generator just generates the missing methods
required to implement marshal.Marshallable.
