Change the rules for how //go:build "file versions" are applied: instead
of considering whether a file version is an upgrade or downgrade from
the -lang version, always use max(fileVersion, go1.21). This prevents
file versions from downgrading the version below go1.21. Before Go 1.21
the //go:build version did not have the meaning of setting the file's
langage version.
This fixes an issue that was appearing in GOPATH builds: Go 1.23.0
started providing -lang versions to the compiler in GOPATH mode (among
other places) which it wasn't doing before, and it set -lang to the
toolchain version (1.23). Because the -lang version was greater than
go1.21, language version used to compile the file would be set to the
//go:build file version. //go:build file versions below 1.21 could cause
files that could previously build to stop building.
For example, take a Go file with a //go:build line specifying go1.10.
If that file used a 1.18 feature, that use would compile fine with a Go
1.22 toolchain. But it would produce an error when compiling with the
1.23.0 toolchain because it set the language version to 1.10 and
disallowed the 1.18 feature. This breaks backwards compatibility: when
the build tag was added, it did not have the meaning of restricting the
language version.

As of CL 580255, the runtime tracks the frame pointer (or base pointer,
bp) when entering syscalls, so that we can use fpTracebackPCs on
goroutines that are sitting in syscalls. That CL mostly got things
right, but missed one very subtle detail.
When calling from Go->C->Go, the goroutine stack performing the calls
when returning to Go is free to move around in memory due to growth,
shrinking, etc. But upon returning back to C, it needs to restore
gp.syscall*, including gp.syscallsp and gp.syscallbp. The way syscallsp
currently gets updated is automagically: it's stored as an
unsafe.Pointer on the stack so that it shows up in a stack map. If the
stack ever moves, it'll get updated correctly. But gp.syscallbp isn't
saved to the stack as an unsafe.Pointer, but rather as a uintptr, so it
never gets updated! As a result, in rare circumstances, fpTracebackPCs
can correctly try to use gp.syscallbp as the starting point for the
traceback, but the value is stale.
This change fixes the problem by just storing gp.syscallbp to the stack
on cgocallback as an unsafe.Pointer, like gp.syscallsp. It also adds a
comment documenting this subtlety; the lack of explanation for the
unsafe.Pointer type on syscallsp meant this detail was missed -- let's
not miss it again in the future.
Now, we have a fix, what about a test? Unfortunately, testing this is
going to be incredibly annoying because the circumstances under which
gp.syscallbp are actually used for traceback are non-deterministic and
hard to arrange, especially from within testprogcgo where we don't have
export_test.go and can't reach into the runtime.
So, instead, add a gp.syscallbp check to reentersyscall and
entersyscallblock that mirrors the gp.syscallbp consistency check. This
probably causes some miniscule slowdown to the syscall path, but it'll
catch the issue without having to actually perform a traceback.
Fixes#69085.

An invalid executable may claim to have a data section bigger than the
executable, causing readData in searchMagic to hit EOF. Since readData
suppresses all EOF errors, searchData would keep attempting to search
through a potentially huge "section" despite readData continuously
failing.
Fix by suppressing EOF only on partial read. If nothing is read, allow
EOF. Note that most of the admittedly tedious EOF handling in this
package is around ensuring we return errNotGoExe in most cases.
This was discovered by the new fuzz test. This fuzz test was inspired
by #69066, though it has not found that specific bug.

filepath.Rel can sometimes return the a relative path that doesn't work.
If the basepath contains a symlink as a path component, and the targpath
does not exist with the directory pointed to by the innermost symlink,
the relative path can "cross" the symlink. The issue is that for the
return value for filepath.Rel to be correct, the ".." components of the
relative path would need to be collapsed before the symlinks are
expanded, but it was verified by doing local testing that the opposite
is true.
go work use (and cmd/go/internal/modload.ReadModFile) both try to
shorten absolute path arguments to relative paths from the working
directory (for better error messages, for instance). Avoid doing so when
the relative path could be wrong using a more conservative rule than the
above: if expanding the symlinks in the current directory produces a
different result, and the relative path we'd return starts with ".." and
then the path separator.

The current implementation has a panic when the database is closed
concurrently with a new connection attempt.
connRequestSet.CloseAndRemoveAll sets connRequestSet.s to a nil slice.
If this happens between calls to connRequestSet.Add and
connRequestSet.Delete, there is a panic when trying to write to the nil
slice. This is sequence is likely to occur in DB.conn, where the mutex
is released between calls to db.connRequests.Add and
db.connRequests.Delete
This change updates connRequestSet.CloseAndRemoveAll to set the curIdx
to -1 for all pending requests before setting its internal slice to nil.
CloseAndRemoveAll already iterates the full slice to close all the request
channels. It seems appropriate to set curIdx to -1 before deleting the
slice for 3 reasons:
1. connRequestSet.deleteIndex also sets curIdx to -1
2. curIdx will not be relevant to anything after the slice is set to nil
3. connRequestSet.Delete already checks for negative indices

The commands to build the bootstrap toolchains and go commands are run
from modules created by two bootstrap go.mod files: one is used when
building toolchain1 and go_bootstrap, and the other is used for
toolchain2 and toolchain3, and the final build. Currently the first has
a go directive specifying go 1.20, and the second one does not have a go
directive at all. This affects the default GODEBUG setting when building
the final toolchain: the default GODEBUG value is based on the go
version of the go.mod file, and when the go.mod file does not have a
version it defaults to go1.16. We should set the go directive on the
bootstrap used for the second half of the builds to use the current go
verison from the std's go.mod file (which is the same as the version on
cmd's go.mod file).
The go.mod file used for the initial bootstrap should have a go

bootstrapping. That version is the current version - 2 rounded down to

[This is a roll-forward of CL 597255, which had to be rolled back
because it broke the windows-arm64 builder, whose current user display
name is unavailable. This new CL fixes the issue by reintroducing the
historical behavior of falling back to the user name instead of
returning an error].
user.Current is slow on Windows sessions connected to an Active
Directory domain. This is because it uses Windows APIs that do RPC
calls to the domain controller, such as TranslateAccountW and
NetUserGetInfo.
This change speeds up user.Current by using the GetUserNameEx API
instead, which is already optimized for retrieving the current user
name in different formats.
These are the improvements I see with the new implementation:
