On Linux one process can call prlimit to change the resource limit
of another process. With this change we treat that as though the
current process called prlimit (or setrlimit) to set its own limit.
The cost is one additional getrlimit system call per fork/exec,
for cases in which the rlimit Cur and Max values differ at startup.
This revealed a bug: the setrlimit (not Setrlimit) function should not
change the cached rlimit. That means that it must call prlimit1, not prlimit.

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.

This can be done efficiently with few instructions.
This also adds MULHDUCC for further codegen improvement.

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

Writes the field for type parameter names for aliases when
the bitstream is >= V2.
This is a no-op at the moment as the writer is hardwired to V1.

1. Replace "rooted path name" with a more accurate "absolute path name".
Using "absolute" seems to be preferred terminology on Unix. On Windows,
there are multiple roots in Windows, thus "a rooted path name" can be
one relative to a drive letter or a server name. Note that Windows'
GetCurrentDirectory documentation [1] also says "the absolute path to the
current directory".
2. Add a note about using $PWD on Unix.
