7833302a62 cmd/go: ignore '@' when cleaning local and absolute file path args
Since CL 194600, search.CleanPaths preserves characters after '@' in
each argument. This was done so that paths could be cleaned while
version queries were preserved. However, local and absolute file paths
may contain '@' characters.

With this change, '@' is treated as a normal character by
search.CleanPaths in local and absolute paths.

Fixes #35115

f91e895de3 syscall: reenable sysctl on iOS
This was disabled due to a report that the App Store rejects the symbol
__sysctl. However, we use the sysctl symbol, which is fine. The __sysctl
symbol is used by x/sys/unix, which needs fixing instead. So, this
commit reenables sysctl on iOS, so that things like net.InterfaceByName
can work again.

This reverts CL 193843, CL 193844, CL 193845, and CL 193846.

3db6d46a4e cmd/compile: add marker for skipping dowidth when tracing typecheck
The root cause of #33658 is that fmt.Printf does have side effects when
printing Type.

typefmt for TINTER will call Type.Fields to get all embedded fields and
methods. The thing is that type.Fields itself will call dowidth, which will
expand the embedded interface, make it non-embedded anymore.

To fix it, we add a marker while we are tracing, so dowidth can know and
return immediately without doing anything.

51504f0a2d go/types: don't update package-external types when checking validity
The recently added type-validity check uses a new field of Named
types for marking (to detect cycles). That field was modified even
if the type was not part of the current package or belonged to the
Universe scope (error type). This led to race conditions if the
package's type was imported by multiple, concurrently type-checked
packages.

A test would be nice but it's a bit cumbersome to set one up.
Verified manually that package-external types are left alone.

16f0f9c8e1 syscall: respect permission bits on file opening on Windows
On Windows, os.Chmod and syscall.Chmod toggle the FILE_ATTRIBUTES_
READONLY flag depending on the permission bits. That's a bit odd but I
guess some compromises were made at some point and this is what was
chosen to map to a Unix concept that Windows doesn't really have in the
same way. That's fine. However, the logic used in Chmod was forgotten
from os.Open and syscall.Open, which then manifested itself in various
places, most recently, go modules' read-only behavior.

This makes syscall.Open consistent with syscall.Chmod and adds a test
for the permission _behavior_ using ioutil. By testing the behavior
instead of explicitly testing for the attribute bits we care about, we
make sure this doesn't regress in unforeseen ways in the future, as well
as ensuring the test works on platforms other than Windows.

In the process, we fix some tests that never worked and relied on broken
behavior, as well as tests that were disabled on Windows due to the
broken behavior and had TODO notes.

Fixes #35033

2e1a6a28df runtime: fix unsafe.Pointer alignment on Linux
Caught by go test -a -short -gcflags=all=-d=checkptr runtime

TestMincoreErrorSign intentionally uses uintptr(1) to get -EINVAL,
but it violates unsafe pointer rules 2. So use another misaligned
pointer add(new(int32), 1), but do not violate unsafe pointer rules.

TestEpollctlErrorSign passes an unsafe.Pointer of &struct{}{} to
Epollctl, which is then casted to epollevent, causes mis-alignment.
Fixing it by exporting epollevent on runtime_test package, so it can be
passed to Epollctl.
