27ed85d4d1 cmd/go: download 1.X.0 instead of 1.X during toolchain upgrade.
This CL modifies the download behavior when downloading a toolchain for 1.21+. Previously, Go would attempt to download 1.X when upgrading the toolchain which would cause the download to fail for 1.21+ since 1.X is an invalid toolchain. We will attempt to download 1.X.0 since that's likely what the user intended.

Additionally, we will also now provide a better error message when the
user provides a language version instead of a toolchain version for
1.21+.

Fixes #66175
Fixes #62278

348b23830d cmd/go: disallow -lto_library in LDFLAGS
The darwin linker allows setting the LTO library with the -lto_library
flag. This wasn't caught by our "safe linker flags" check because it
was covered by the -lx flag used for linking libraries. This change
adds a specific check for excluded flags which otherwise satisfy our
existing checks.

Loading a mallicious LTO library would allow an attacker to cause the
linker to execute abritrary code when "go build" was called.

Thanks to Juho Forsén of Mattermost for reporting this issue.

be003bd00b runtime: don't re-raise ignored signal
If a signal lands on a non-Go thread, and Go code doesn't want to
handle it, currently we re-raise the signal in the signal handler
after uninstalling our handler, so the C code can handle it.

But if there is no C signal handler and the signal is ignored,
there is no need to re-raise the signal. Just ignore it. This
avoids uninstalling and reinstalling our handler, which, for some
reason, changes errno when TSAN is used. And TSAN does not like
errno being changed in the signal handler.

Not really sure if this is the bset of complete fix, but it does
fix the immediate problem, and it seems a reasonable thing to do
by itself.

Test case is CL 581722.

Fixes #66427.

to keeping OneNewExtraM, but it would still be fairly optimistic. It's
trivial to bring back, so delete it for now.

9050ce9b33 crypto/x509: include OID in duplicate extension error message
Include the OID in the error message when parsing X.509
certificates. This should ease fixing such issues, because
users can clearly identify the duplicate extension via the
reported error. Previously, this wasn't possible and
required either manually adjusting the standard library or
inspecting the certificate with various debugging tools.

ac174400f4 hash/crc32: improve asm for ppc64SlicingUpdateBy8
Improvements are made in the assembler code which improves  time and
space by 9-10%.
1. ANDCC, followed by SLD is combined and replaced by CLRLSLDI.
2. MOVWZ can use an indexed load and eliminate an ADD instruction in some cases.
	Example: ADD R7,R10,R7 followed by MOVWZ 0(R7),R5 can be replaced with just MOVWZ (R7)(R10),R5.
3. Optimizations for the block after the "short" label includes the same MOVWZ use of indexed load, as well as other improvements.

The gain from code  changes can be seen as follows, generated by
benchstat:

20130cc36a syscall: remove references to SYS_syscall on openbsd
OpenBSD 7.5 no longer has a syscall symbol in libc. This will
typically result in external linking failures since the syscall
package still has a reference to an undefined `syscall' symbol.
Remove these references and return ENOSYS if syscall.Syscall* or
syscall.RawSyscall* are used for a system call number that does not
currently have an internal remapping.

Fixes #63900

8841f50d98 syscall: reroute SYS_IOCTL and SYS_SYSCTL on openbsd
OpenBSD 7.5 no longer supports indirect syscalls. A number of Go
packages make use of syscall.Syscall with SYS_IOCTL or SYS_SYSCTL,
since neither is well supported by golang.org/x/sys/unix. Reroute
calls with either of these system call numbers to the respective
libc stub so that they continue to work.

Updates #63900

17fce63239 cmd/dist,internal/platform: temporarily disable race detector on openbsd/amd64
Unfortunately, LLVM TSAN decided to remove OpenBSD support, which
means that the syso files cannot currently be regenerated (see #52090).
The race_openbsd.syso contains a reference to the syscall symbol,
which has been removed from OpenBSD's libc in 7.5. As such, this
means that the race detector no longer works on openbsd/amd64 (at
least until LLVM TSAN support is reinstated for OpenBSD).

99fc317948 cmd/go: add flag values to counter for buildmode
Usually, when we increment counters for flags, the counter only contains
the flag name. For the buildmode flag, we now include the flag value
because there's a limited set of values.

We can't use CountFlags directly anymore since we have different
behavior for buildmode.

the counter registration mechanism, and uses telemetry.NewCounter to
create new counters instead. It keeps the tests that check that at least
one counter is incremented if the go command is invoked in a script test.

This CL add testenv.ParallelOn64Bit for tests
that can be parallel on 64-bit machines,
it is not parallel on 32-bit machines,
because CL 564995 require the same API.

Goids are designed to be big enough that they will never be reused:
a uint64 is enough to generate a new goroutine every nanosecond

should probably stop and pick up some security updates.

This note was added in CL 70993 and appears to have just been
a misunderstanding by the CL author.

cf05873029 net/http: represent multi wildcards properly
The routing tree used for matching ServeMux patterns used the
key "*" to hold a child node for a multi-segment wildcard.
The problem is that "*" is a valid path segment, which confused
the matching algorithm: it would fetch the multi wildcard child
when looking for the literal child for "*".

Eschew clever encodings. Use a separate field in the node to
represent the multi wildcard child.

Fixes #67067.
