Richard Musiol 7d9649bf0d syscall/js: rename js.Callback to js.Func
The name "Callback" does not fit to all use cases of js.Callback.
This commit changes its name to Func. Accordingly NewCallback
gets renamed to FuncOf, which matches ValueOf and TypedArrayOf.

The package syscall/js is currently exempt from Go's compatibility
promise and js.Callback is already affected by a breaking change in
this release cycle. See #28711 for details.

Clément Chigot 7937466022 syscall, cmd/go/internal/lockedfile: remove Flock syscall for aix/ppc64
AIX doesn't provide flock() syscall, it was previously emulated by fcntl
calls. However, there are some differences between a flock() syscall and
a flock() using fcntl. Therefore, it's safer to remove it and just
provide FcntlFlock.

Thus, lockedfile implementation must be moved to use FcntlFlock on aix/ppc64.

Elias Naur e985ba8023 syscall: avoid "64"-postfixed libSystem syscalls on iOS
The stat(2) man page contain this comment about the 64-bit versions
of the system file functions:

"Platforms that were released after these updates only have the
newer variants available to them.  These platforms have the macro
_DARWIN_FEATURE_ONLY_64_BIT_INODE defined."

It turns out that on iOS the _DARWIN_FEATURE_ONLY_64_BIT_INODE is
defined and that even though the "64"-postfixed versions are
accessible they are deemed private. Apps that refer to private
API are not admissible on App Store, and after the Go runtime
started using libSystem instead of direct syscalls, the App Store
submission checks reject apps built with Go tip.

The fix is simple: use the non-postfixed versions on iOS.

getdirentries(2) is not changed; it is not available at all on iOS
and needs replacement.

Richard Musiol 9ef1455324 syscall: add dummy SIGTERM constant to js/wasm
The js/wasm architecture does not support signals at all, but there are
already some signal constants defined because of stdlib dependencies.
This change adds a dummy constant for syscall.SIGTERM as well, to make
js/wasm compatible with more existing Go code.

There is the Go proverb "Syscall must always be guarded with build
tags.", so code should not expect syscall.SIGTERM to exist. Still,
adding SIGTERM should do more good than harm.

Austin Clements af1bfe0aa3 runtime: correct ABI information for all functions
There are three cases where we don't currently have the visibility to
get the ABIs of runtime symbols right, which this CL fixes:

1. For Go functions referenced from non-Go code in other packages.
   This is runtime.morestackc (which is referenced from function
   prologues) and a few syscall symbols. For these we need to generate
   ABI0 wrappers, so this CL adds dummy calls in the assembly code to
   force wrapper generation. There are many other cross-package
   references to runtime and runtime/internal/atomic, but these are
   handled specially by cmd/go.

2. For calls generated by the compiler to runtime Go functions, there
   are a few symbols that aren't declared in builtins.go because we've
   never needed their type information before. Now we at least need
   their ABI information, so these are added to builtins.go.

3. For calls generated by the compiler to runtime assembly functions,
   the compiler is going to assume the internal ABI is available, so
   we add Go stubs to the runtime to trigger wrapper generation. For
   these we're probably going to want to provide internal ABI
   definitions directly in the assembly for performance, but for now
   the ABIs are the same so it doesn't matter.

For #27539.

Brad Fitzpatrick 3813edf26e all: use "reports whether" consistently in the few places that didn't
Go documentation style for boolean funcs is to say:

    // Foo reports whether ...
    func Foo() bool

(rather than "returns true if")

This CL also replaces 4 uses of "iff" with the same "reports whether"
wording, which doesn't lose any meaning, and will prevent people from
sending typo fixes when they don't realize it's "if and only if". In
the past I think we've had the typo CLs updated to just say "reports
whether". So do them all at once.

(Inspired by the addition of another "returns true if" in CL 146938
in fd_plan9.go)

Created with:

$ perl -i -npe 's/returns true if/reports whether/' $(git grep -l "returns true iff" | grep -v vendor)
$ perl -i -npe 's/returns true if/reports whether/' $(git grep -l "returns true if" | grep -v vendor)

Yuval Pavel Zholkover dc6eb200dd syscall: FreeBSD 12 ino64 support
This is similar to CL 136816 for x/sys/unix, changing the FreeBSD ABI to use 64-bit inodes in
Stat_t, Statfs_t, and Dirent types.

The changes are forward compatible, that is FreeBSD 10.x, 11.x continue to use their current sysnum numbers.
The affected types are converted to the new layout (with some overhead).
Thus the same statically linked binary should work using the native sysnums (without any conversion) on FreeBSD 12.

Breaking API changes in package syscall are:
Mknod takes a uint64 (C dev_t) instead of int.
Stat_t: Dev, Ino, Nlink, Rdev, Gen became uint64.
  Atimespec, Mtimespec, Ctimespec, Birthtimespec renamed to Atim, Mtim, Ctim, Birthtim respectively.

Statfs_t: Mntonname and Mntfromname changed from [88]int8 to [1024]int8 arrays.

Dirent: Fileno became uint64, Namlen uint16 and an additional field Off int64 (currently unused) was added.

The following commands were run to generate ztypes_* and zsyscall_* on FreeBSD-12.0-ALPHA6 systems (GOARCH=386 were run on the same amd64 host):
GOOS=freebsd GOARCH=amd64 ./mksyscall.pl -tags freebsd,amd64 syscall_bsd.go syscall_freebsd.go syscall_freebsd_amd64.go |gofmt >zsyscall_freebsd_amd64.go
GOOS=freebsd GOARCH=amd64 go tool cgo -godefs types_freebsd.go | GOOS=freebsd GOARCH=amd64 go run mkpost.go >ztypes_freebsd_amd64.go

GOOS=freebsd GOARCH=386 ./mksyscall.pl -l32 -tags freebsd,386 syscall_bsd.go syscall_freebsd.go syscall_freebsd_386.go |gofmt >zsyscall_freebsd_386.go
GOOS=freebsd GOARCH=386 go tool cgo -godefs types_freebsd.go | GOOS=freebsd GOARCH=386 go run mkpost.go >ztypes_freebsd_386.go

GOOS=freebsd GOARCH=arm ./mksyscall.pl -l32 -arm -tags freebsd,arm syscall_bsd.go syscall_freebsd.go syscall_freebsd_arm.go |gofmt >zsyscall_freebsd_arm.go
GOOS=freebsd GOARCH=arm go tool cgo -godefs -- -fsigned-char types_freebsd.go | GOOS=freebsd GOARCH=arm go run mkpost.go >ztypes_freebsd_arm.go

The Kevent struct was changed to use the FREEBSD_COMPAT11 version always (requiring the COMPAT_FREEBSD11 kernel option FreeBSD-12, this is the default).

The definitions of ifData were not updated, their functionality in has have been replaced by vendored golang.org/x/net/route.

freebsdVersion initialization was dropped from init() in favor of a sync.Once based wrapper - supportsABI().

Updates #22448.

This commit makes syscall on js/wasm use the asynchronous variants
of functions in Node.js' fs module. This enables concurrency
and allows the API of the fs module to be implemented with an
alternative backend that only supports asynchronous operations.

Elias Naur f25656d392 syscall: replace lstat, lchown, stat to please Android O
Implement Lstat with fstatat and Lchown with Fchownat on
linux/amd64, linux/arm and linux/386. Furthermore, implement Stat
with fstatat on linux/arm and linux/386. Linux/arm64 already had
similar replacements.

The fstatat and fchownat system calls were added in kernel 2.6.16,
which is before the Go minimum, 2.6.23.

The three syscalls then match the android bionic implementation
and avoids the Android O seccomp filter.

Fixes #27797

Tobias Klauser eee1cfb0b2 syscall: correct argument order for SyncFileRange syscall on linux/ppc64{,le}
On linux/ppc64{,le} the SYS_SYNC_FILE_RANGE2 syscall is used to
implement SyncFileRange. This syscall has a different argument order
than SYS_SYNC_FILE_RANGE. Apart from that the implementations of both
syscalls are the same, so use a simple wrapper to invoke the syscall
with the correct argument order.

Emmanuel T Odeke be10ad7622 internal/poll: use F_FULLFSYNC fcntl for FD.Fsync on OS X
As reported in #26650 and also cautioned on the man page
for fsync on OS X, fsync doesn't properly flush content
to permanent storage, and might cause corruption of data if
the OS crashes or if the drive loses power. Thus it is recommended
to use the F_FULLFSYNC fcntl, which flushes all buffered data to
permanent storage and is important for applications such as
databases that require a strict ordering of writes.

Also added a note in syscall_darwin.go that syscall.Fsync is
not invoked for os.File.Sync.

Fixes #26650.

Tobias Klauser 88aa208024 syscall: use private copy of ustat_t on Linux
Port CL 120295 from golang.org/x/sys/unix to the syscall package.

The ustat syscall has been deprecated on Linux for a long time and the
upcoming glibc 2.28 will remove ustat.h and it can no longer be used to
to generate the Ustat_t wrapper type. Since Linux still provides the
syscall, let's not break this functionality and add a private copy of
struct ustat so Ustat_t can still be generated.

Fixes golang/go#25990
