client/web: dedupe packages in yarn.lock (#11327)
Run yarn-deduplicate on yarn.lock to dedupe packages. This is being done
to reduce the number of redundant packages fetched by yarn when existing
versions in the lockfile satisfy the version dependency we need.

util/linuxfw: add container-friendly IPv6 NAT check (#11353)
Remove IPv6 NAT check when routing is being set up
using nftables.
This is unnecessary as support for nftables was
added after support for IPv6.
https://tldp.org/HOWTO/Linux+IPv6-HOWTO/ch18s04.html
https://wiki.nftables.org/wiki-nftables/index.php/Building_and_installing_nftables_from_sources

Additionally, run an extra check for IPv6 NAT support
when the routing is set up with iptables.
This is because the earlier checks rely on
being able to use modprobe and on /proc/net/ip6_tables_names
being populated on start - these conditions are usually not
true in container environments.

Sonia Appasamy c58c59ee54 {ipn,cmd/tailscale/cli}: move ServeConfig mutation logic to ipn/serve
Moving logic that manipulates a ServeConfig into recievers on the
ServeConfig in the ipn package. This is setup work to allow the
web client and cli to both utilize these shared functions to edit
the serve config.

Any logic specific to flag parsing or validation is left untouched
in the cli command. The web client will similarly manage its
validation of user's requested changes. If validation logic becomes
similar-enough, we can make a serve util for shared functionality,
which likely does not make sense in ipn.

Percy Wegmann 232a2d627c tailfs: only impersonate unprivileged user if able to sudo -u as that user
When serving TailFS shares, tailscaled executes another tailscaled to act as a
file server. It attempts to execute this child process as an unprivileged user
using sudo -u. This is important to avoid accessing files as root, which would
result in potential privilege escalation.

Previously, tailscaled assumed that it was running as someone who can sudo -u,
and would fail if it was unable to sudo -u.

With this commit, if tailscaled is unable to sudo -u as the requested user, and
tailscaled is not running as root, then tailscaled executes the the file server
process under the same identity that ran tailscaled, since this is already an
unprivileged identity.

In the unlikely event that tailscaled is running as root but is unable to
sudo -u, it will refuse to run the child file server process in order to avoid
privilege escalation.

Percy Wegmann 2d5d6f5403 ipn,wgengine: only intercept TailFS traffic on quad 100
This fixes a regression introduced with 993acf4 and released in
v1.60.0.

The regression caused us to intercept all userspace traffic to port
8080 which prevented users from exposing their own services to their
tailnet at port 8080.

Now, we only intercept traffic to port 8080 if it's bound for
100.100.100.100 or fd7a:115c:a1e0::53.

Update typescript to 5.3.3. This is a major bump from the previous
version of 4.8.3. This also requires adding newer versions of
@typescript-eslint/eslint-plugin and @typescript-eslint/parser to our
resolutions as eslint-config-react-app pulls in versions that otherwise
do not support typescript 5.x.

eslint-config-react-app has not been updated in 2 years and is seemingly
abandoned, so we may wish to fork it or move to a different eslint config
in the future.

Andrew Dunham c5abbcd4b4 wgengine/netstack: add a per-client limit for in-flight TCP forwards
This is a fun one. Right now, when a client is connecting through a
subnet router, here's roughly what happens:

1. The client initiates a connection to an IP address behind a subnet
   router, and sends a TCP SYN
2. The subnet router gets the SYN packet from netstack, and after
   running through acceptTCP, starts DialContext-ing the destination IP,
   without accepting the connection¹
3. The client retransmits the SYN packet a few times while the dial is
   in progress, until either...
4. The subnet router successfully establishes a connection to the
   destination IP and sends the SYN-ACK back to the client, or...
5. The subnet router times out and sends a RST to the client.
6. If the connection was successful, the client ACKs the SYN-ACK it
   received, and traffic starts flowing

As a result, the notification code in forwardTCP never notices when a
new connection attempt is aborted, and it will wait until either the
connection is established, or until the OS-level connection timeout is
reached and it aborts.

To mitigate this, add a per-client limit on how many in-flight TCP
forwarding connections can be in-progress; after this, clients will see
a similar behaviour to the global limit, where new connection attempts
are aborted instead of waiting. This prevents a single misbehaving
client from blocking all other clients of a subnet router by ensuring
that it doesn't starve the global limiter.

Also, bump the global limit again to a higher value.

¹ We can't accept the connection before establishing a connection to the
remote server since otherwise we'd be opening the connection and then
immediately closing it, which breaks a bunch of stuff; see #5503 for
more details.
