Currently we only track visited (copied) packages when a copy is
required. When a copy is not required, we will rewalk each package's
entire dependency graph every time we see it, which is terribly
inefficient.
Pull the visited package check up a level so that we visit packages only
once regardless of how many times they are visited.

that, while not strictly a bug, caused a bunch of test failures
in a large codebase. Rather than add behavior changes in a 10 year
old package, revert to the old behavior: a context cancelation
between Rows.Next reporting false and a call to Rows.Err should
not result in Rows.Err returning the context error.
That behavior was accidentally added in CL 497675 as part of changing
how contexts and Rows iteration worked.

heapObjectsCanMove is always false in the current garbage collector.
It exists for go4.org/unsafe/assume-no-moving-gc, which is an
unfortunate idea that had an even more unfortunate implementation.
Every time a new Go release happened, the package stopped building,
and the authors had to add a new file with a new //go:build line, and
then the entire ecosystem of packages with that as a dependency had to
explicitly update to the new version. Many packages depend on
assume-no-moving-gc transitively, through paths like
inet.af/netaddr -> go4.org/intern -> assume-no-moving-gc.
This was causing a significant amount of friction around each new
release, so we added this bool for the package to //go:linkname
instead. The bool is still unfortunate, but it's not as bad as
breaking the ecosystem on every new release.
If the Go garbage collector ever does move heap objects, we can set
this to true to break all the programs using assume-no-moving-gc.

We used to inconsistently run certificate verification on the server on
resumption, but not on the client. This made TLS 1.3 resumption pretty
much useless, as it didn't save bytes, CPU, or round-trips.
This requires serializing the verified chains into the session ticket,
so it's a tradeoff making the ticket bigger to save computation (and for
consistency).
The previous behavior also had a "stickyness" issue: if a ticket
contained invalid certificates, they would be used even if the client
had in the meantime configured valid certificates for a full handshake.
We also didn't check expiration on the client side on resumption if
InsecureSkipVerify was set. Again for consistency, we do that now.
Also, we used to run VerifyPeerCertificates on resumption even if
NoClientCerts was set.

All OpenSSL tests now test operation with EMS. To test a handshake
*without* EMS we need to pass -Options=-ExtendedMasterSecret which is
only available in OpenSSL 3.1, which breaks a number of other tests.

Implements net.FileListener and net.FileConn for wasip1.
net.FileListener can be used with a pre-opened socket. If the WASM
module knows the file descriptor, a listener can be constructed with:
l, err := net.FileListener(os.NewFile(fd, ""))
If the WASM module does not know the file descriptor, but knows that at
least one of the preopens is a socket, it can find the file descriptor
and construct a listener like so:
func findListener() (net.Listener, error) {
// We start looking for pre-opened sockets at fd=3 because 0, 1,
// and 2 are reserved for stdio. Pre-opened directories also
// start at fd=3, so we skip fds that aren't sockets. Once we
// reach EBADF we know there are no more pre-opens.
for preopenFd := uintptr(3); ; preopenFd++ {
l, err := net.FileListener(os.NewFile(preopenFd, ""))
var se syscall.Errno
switch errors.As(err, &se); se {
case syscall.ENOTSOCK:
continue
case syscall.EBADF:
err = nil
}
return l, err
}
}
A similar strategy can be used with net.FileConn and pre-opened
connection sockets.
The wasmtime runtime supports pre-opening listener sockets:
$ wasmtime --tcplisten 127.0.0.1:8080 module.wasm
