Robert Griesemer ee402e9882 go/types, types2: use exact unification for component types
This change defines two unification modes used to control unification:

- assign  set when unifying types involved in an assignment
- exact   if set, types unify if they can be made identical

Currently, unification is inexact: when a defined type is compared
against a type literal, the underlying type of the defined type is
considered. When channel types are compared, the channel direction
is ignored. And when defined types are compared where one (or both)
are interfaces, interface unification is used.

By contrast, exact unification requires types to match exactly:
if they can be unified, the types must be identical (with suitable
type arguments).

Exact unification is required when comparing component types.
For instance, when unifying func(x P) with func(x Q), the two
signatures unify only if P is identical to Q per Go's assignment
rules.

Until now we have ignored exact unification and made due with inexact
unification everywhere, even for component types. In some cases this
led to infinite recursions in the unifier, which we guarded against
with a depth limit (and unification failure).

Go's assignmemt rules allow inexact matching at the top-level but
require exact matching for element types.

This change passes 'assign' to the unifier when unifying parameter
against argument types because those follow assignment rules.
When comparing constraints, inexact unification is used as before.

In 'assign' mode, when comparing element types, the unifyier is
called recursively, this time with the 'exact' mode set, causing
element types to be compared exactly. If unification succeeds for
element types, they are identical (with suitable type arguments).

This change fixes #60460. It also fixes a bug in the test for
issue #60377. We also don't need to rely anymore on the recursion
depth limit (a temporary fix) for #59740. Finally, because we use
exact unification when comparing element types which are channels,
errors caused by assignment failures (due to inexact inference which
succeeded when it shouldn't have) now produce the correct inference
error.

Fixes #60460.
For #60377.
For #59740.

Robert Griesemer f78483eaac go/types, types2: add unifyMode to unifier, pass it through
Pass a mode parameter through all unifier calls but make no use of it.
When unifying type elements (components of composite types), use emode,
which currently is set to mode.

Preparatory step to fix #60460. Factoring out this mechanical change
will make the actual fix smaller and easier to review and understand.
Because this change doesn't affect the behavior of the unifier, it is
safe.

For #60460.

Michael Anthony Knyszek 8c5d1a41ad cmd/cgo: rewrite pointer passing rules in terms of pinning
With the introduction of runtime.Pinner, we need to update the cgo
pointer passing rules to accomodate the new functionality. These rule
changes are easier to describe if the rest of the pointer passing rules
are described in terms of pinning as well (Go memory is implicitly
pinned when a pointer to it is passed to a C function, and implicitly
unpinned when that function returns).

For #46787.

Russ Cox 77bdf6d0e0 cmd/go: lock in new toolchain semantics
The design doc says 'toolchain' lines apply even if the default
toolchain is older than the one specified in the toolchain line.
However, that leads to various confusing behavior and security issues.
Instead, treat toolchain as a min go version that only applies
in the current module (not in dependencies).

As an example of confusing behavior / security issue, if I install
Go 1.30 and then run 'go build' in a module I've checked out,
I expect to use Go 1.30 or newer, not to silently use an older toolchain
that may have security problems fixed in Go 1.30.
Making toolchain a min establishes that guarantee.

Also clean up the tests quite a bit.

Finally drop + from the acceptable version suffixes; we use + for +auto and +path.

For #57001.

If we run 'go get go@1.40' or 'go get m@v' where m has a go.mod
that says 'go 1.40', we need to write a new go.mod that says 'go 1.40'.
But we can't be sure we know how to write a Go 1.40-compatible go.mod.
Instead, download the latest point release of Go 1.40 and invoke it to
finish the get command.

This patch reverts a portion of the changes in CL 443715, specifically
the code in initorder that treats coverage counter variables as special
with respect to init order. The special casing is no longer needed
now after a change to the way coverage instrumention is done (the go and
cover cmds now make sure that coverage variables appear first in
the compilation order).

Than McIntosh 89a3bb69ce cmd/{cover,go}: revise fix for pkg init order change with -cover
This patch contains a revised fix for issue #56293, switching to a
scheme in which coverage counter variables and meta-data variables are
written to a separate output file as opposed to being tacked onto the
end of an existing rewritten source file.

The advantage of writing counter vars to a separate file is that the
Go command can then present that file as the first source file to the
compiler when the package is built; this will ensure that counter
variable are treated as lexically "before" any other variable that
might call an instrumented function as part of its initializer.

Updates #56293.

Bryan C. Mills 58e42b946b cmd/go/internal/modload: break more cycles in readModGraph
Before CL 471595, modload.readModGraph in module with graph pruning
enabled only ever chased down transitive dependencies of unpruned
roots, so pruned dependencies couldn't cause cycles and we didn't
need to dedup them in the loading queue.

However, in 'go get' we are now passing in a set of upgraded modules
to unprune, and those upgraded modules can potentially contain cycles,
leading to an infinite loop during loading.

We have two options for a fix: we could either drop the 'unprune'
check in the enqueue operation (and instead expand the 'unprune'
requirements in a separate pass, as we do in workspace mode), or we
could check for cycles for all modules (not just the ones that are
naturally unpruned). The latter option makes it clearer that this
process must terminate, so we choose that.

(It may be possible to clean up and simplify the workspace-mode case
now that we are passing in the 'unprune' map, but for now we're
looking for a minimal fix for the Go 1.21 release.)

Fixes #60490.

Mark Ryan bfa25c3f6c internal/bytealg: fix alignment code in compare_riscv64.s
The riscv64 implementation of compare has an optimization that is
applied when both pointers share the same alignment but that alignment
is not 8 bytes.  In this case it tries to align both pointers to an 8 byte boundaries,
by individually comparing the first few bytes of each buffer.  Unfortunately,
the existing code is incorrect.  It adjusts the pointers by the wrong number
of bytes resulting, in most cases, in pointers that are not 8 byte aligned.

This commit fixes the issue by individually comparing the first
(8 - (pointer & 7)) bytes of each buffer rather than the first
(pointer & 7) bytes.

We also remove an unnecessary immediate MOV instruction.

This particular optimization is not covered by any of the existing
benchmarks so a new benchmark, benchmarkCompareBytesBigBothUnaligned,
is provided.  The benchmark tests the case where both pointers have
the same alignment but may not be 8 byte aligned.  Results of the
new benchmark along with some of the existing benchmarks generated on
a SiFive HiFive Unmatched A00 with 16GB of RAM running Ubuntu 23.04

The earlier CL 497675 for #60304 introduced a behavior change
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.

Russ Cox 055c186f53 runtime: add heapObjectsCanMove
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.

Filippo Valsorda d4bd855cfb crypto/tls: don't reverify but check certificate expiration on resumption
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.

Filippo Valsorda 4406ed6d4e crypto/tls: implement Extended Master Secret
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.

Updates #43922

Chris O'Hara a17de43ef1 net: implement wasip1 FileListener and FileConn
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
