os: add clone(CLONE_PIDFD) check to pidfd feature check
clone(CLONE_PIDFD) was added in Linux 5.2 and pidfd_open was added in
Linux 5.3. Thus our feature check for pidfd_open should be sufficient to
ensure that clone(CLONE_PIDFD) works.
Unfortuantely, some alternative Linux implementations may not follow
this strict ordering. For example, QEMU 7.2 (Dec 2022) added pidfd_open,
but clone(CLONE_PIDFD) was only added in QEMU 8.0 (Apr 2023).
Debian bookworm provides QEMU 7.2 by default.
Fixes #69259.

cmd/compile,cmd/internal/obj/riscv: always provide ANDN, ORN and XNOR for riscv64
The ANDN, ORN and XNOR RISC-V Zbb extension instructions are easily
synthesised. Make them always available by adding support to the
riscv64 assembler so that we either emit two instruction sequences,
or a single instruction, when permitted by the GORISCV64 profile.
This means that these instructions can be used unconditionally,
simplifying compiler rewrite rules, codegen tests and manually
written assembly.
Around 180 instructions are removed from the Go binary on riscv64
when built with rva22u64.

cmd/go: explicitly add default GODEBUG to linker config
Previously we expected the default GODEBUG that's embedded in the binary
to be taken into account for build actionIDs through the build info. The
build info contains the default GODEBUG for a package main, and then
that build info is used to generate the action id. But tests of packages
other than main do not have buildinfo set on them. So the default
GODEBUG isn't taken into account in the action id for those tests.
Explicitly include GODEBUG when generating all link actions' action ids
to make sure it's always present.

asm_riscv64.h will be used to define macros for each riscv64
extension that is not part of the rva20u64 base profile but that the

specified a more capable profile in the GORISCV64 variable. This will
allow us, for example, to test for the hasZba macro in those assembly

Zba. We will not need to update every assembly language file that

cmd/compile: emit tail call wrappers when possible
Use OTAILCALL in wrapper if the receiver and method are both pointers and it is
not going to be inlined, similar to how it is done in reflectdata.methodWrapper.
Currently tail call may be used for functions with identical argument types.
This change updates wrappers where both wrapper and the wrapped method's
receiver are pointers. In this case, we have the same signature for the
wrapper and the wrapped method (modulo the receiver's pointed-to types),
and do not need any local variables in the generated wrapper (on stack)
because the arguments are immediately passed to the wrapped method in place
(without need to move some value passed to other register or to change any
argument/return passed through stack). Thus, the wrapper does not need its
own stack frame.
This applies to promoted methods, e.g. when we have some struct type U with
an embedded type *T and construct a wrapper like
func (recv *U) M(arg int) bool { return recv.T.M(i) }
See also test/abi/method_wrapper.go for a running example.
Code size difference measured with this change (tried for x86_64):
etcd binary:
.text section size: 21472251 -> 21432350 (0.2%)
total binary size: 32226640 -> 32191136 (0.1%)

cmd/go: add an exception for 'go telemetry off' to not open counters
There is the expectation that if 'go telemetry off' is run with a clean
home directory that no counter files are written. But we were writing
counters in that case because the act of turning telemetry off was done
after the act of opening the counter files, so the counter files were
opened depending on what the previous mode was. Add a special check that
the command is not 'go telemetry off' before opening counter files.

internal/syscall/unix: Eaccess: return ENOSYS on Android
On Android, faccessat2 syscall (which supports flags like AT_EACCESS) is
not allowed, so syscall.Faccessat tries to emulate AT_EACCESS check in
userspace using os.Stat, os.Geteuid etc.
Also, according to [1],
> Android doesn't have setuid programs, and never runs code with euid!=uid.
This means on Android the proper AT_EACCESS check is neither possible
nor really needed.
Let's skip the syscall.Faccessat userspace emulation of AT_EACCESS
check and return ENOSYS, so the callers can use a fallback.

internal/syscall/unix: implement Eaccess on all unix platforms
Eaccess, initially added by CL 414824 for linux only, was later
implemented for freebsd (CL 531155), netbsd (CL 531876), dragonfly
(CL 532675), openbsd (CL 538836), and darwin (CL 579976).
The only unix platforms which lack Eaccess are Solaris/Illumos and AIX.
For AIX, syscall.Faccessat is already available, the only missing piece
was AT_EACCESS constant. Let's take it from [1], which, judging by a few
other known AT_ constants, appears to be accurate.
For Solaris, wire the faccessat using the same logic as in the syscall
package.
Now, when we have faccessat for every unix, we can drop eaccess_other.go
and consolidate Eaccess implementations to use faccessat.

cmd/compile/internal/syntax: handle parentheses around constraints consistently
Generally, the parser strips (i.e., does not record in the syntax tree)
unnecessary parentheses. Specifically, given a type parameter list of
the form
[P (C),]
it records it as
[P C]
and then no comma is required when printing. However it did only strip
one level of parentheses, and
[P ((C)),]
made it through, causing a panic when printing. Somewhat related,
the printer stripped parentheses around constraints as well.
This CL implements a more consistent behavior:
1) The parser strips all parentheses around constraints. For testing
purposes, a local flag (keep_parens) can be set to retain the
parentheses.
2) The printer code now correctly intruces a comma if parentheses
are present (e.g., when testing with keep_parens). This case does
not occur in normal operation.
3) The printer does not strip parentheses around constraints since
the parser does it already.

go/build/constraint: add parsing limits
Limit the size of build constraints that we will parse. This prevents a
number of stack exhaustions that can be hit when parsing overly complex
constraints. The imposed limits are unlikely to ever be hit in real

encoding/gob: cover missed cases when checking ignore depth
This change makes sure that we are properly checking the ignored field
recursion depth in decIgnoreOpFor consistently. This prevents stack
exhaustion when attempting to decode a message that contains an
extremely deeply nested struct which is ignored.

os: don't fail TestGetwdDeepWithPWDSet if TMPDIR has a symlink
When testing with PWD set, it's possible for the stat of PWD to fail
with ENAMETOOLONG, and for syscall.Getwd to fail for the same reason.
If PWD contains symlinks, the fallback code won't know about them.
If Getwd returns the same result as PWD with resolved symlinks,
the test should not fail.

Calls to os.Getwd were needed to set the cwd for go build to an absolute

filepath.Abs(cmd.Dir), so it looks like an absolute path is not

Among other things, this should fix a regression in printf
whereby materialized aliases caused "any" and "interface{}"
in printf signatures not to be recognized as identical.
It also updates ureader.go used by vendored x/tools during

crypto/internal/nistec: Avo port of p256_asm_amd64.s
This implementation utilizes the same registers found in the reference
implementation, aiming to produce a minimal semantic diff between the
Avo-generated output and the original hand-written assembly.
To verify the Avo implementation, the reference and Avo-generated
assembly files are fed to `go tool asm`, capturing the debug output into
corresponding temp files. The debug output contains supplementary
metadata (line numbers, instruction offsets, and source file references)
that must be removed in order to obtain a semantic diff of the two
files. This is accomplished via a small utility script written in awk.
The reference assembly file does not specify a frame size for a number
of the defined assembly functions. Avo automatically infers the frame
size when generating the TEXT directive, leading to a diff on those
lines.
