Filippo Valsorda df52396943 [release-branch.go1.11-security] crypto/x509: limit number of signature checks for each verification
That number grows quadratically with the number of intermediate
certificates in certain pathological cases (for example if they all have
the same Subject) leading to a CPU DoS. Set a fixed budget that should
fit all real world chains, given we only look at intermediates provided
by the peer.

The algorithm can be improved, but that's left for follow-up CLs:

    * the cache logic should be reviewed for correctness, as it seems to
      override the entire chain with the cached one
    * the equality check should compare Subject and public key, not the
      whole certificate
    * certificates with the right SKID but the wrong Subject should not
      be considered, and in particular should not take priority over
      certificates with the right Subject

Ian Lance Taylor 9cc0209ef1 [release-branch.go1.11] cmd/go: don't fail if requested Go version is later than current one
This is a partial backport of CL 147278 from tip to the Go 1.11 branch.

Change the behavior when the go.mod file requests a Go version that is
later than the current one. Previously cmd/go would give a fatal error
in this situation. With this change it attempts the compilation, and
if (and only if) the compilation fails it adds a note saying that the
requested Go version is newer than the known version.  This is as
described in https://golang.org/issue/28221.

Ian Lance Taylor 6fa0ace128 [release-branch.go1.11] cmd/cgo: use field alignment when setting field offset
The old code ignored the field alignment, and only looked at the field
offset: if the field offset required padding, cgo added padding. But
while that approach works for Go (at least with the gc toolchain) it
doesn't work for C code using packed structs. With a packed struct the
added padding may leave the struct at a misaligned position, and the
inserted alignment, which cgo is not considering, may introduce
additional, unexpected, padding. Padding that ignores alignment is not
a good idea when the struct is not packed, and Go structs are never
packed. So don't ignore alignment.

Robert Griesemer 6971090515 [release-branch.go1.11] go/types: avoid certain problems with recursive alias type declarations
It is possible to create certain recursive type declarations involving
alias types which cause the type-checker to produce an (invalid) type
for the alias because it is not yet available. By type-checking alias
declarations in a 2nd phase, the problem is mitigated a bit since it
requires more convoluted alias declarations for the problem to appear.

Also re-enable testing of fixedbugs/issue27232.go again (which was the
original cause for this change).

Robert Griesemer 62b47c284c [release-branch.go1.11] cmd/compile: reintroduce work-around for cyclic alias declarations
This change re-introduces (temporarily) a work-around for recursive
alias type declarations, originally in https://golang.org/cl/35831/
(intended as fix for #18640). The work-around was removed later
for a more comprehensive cycle detection check. That check
contained a subtle error which made the code appear to work,
while in fact creating incorrect types internally. See #25838
for details.

By re-introducing the original work-around, we eliminate problems
with many simple recursive type declarations involving aliases;
specifically cases such as #27232 and #27267. However, the more
general problem remains.

This CL also fixes the subtle error (incorrect variable use when
analyzing a type cycle) mentioned above and now issues a fatal
error with a reference to the relevant issue (rather than crashing
later during the compilation). While not great, this is better
than the current status. The long-term solution will need to
address these cycles (see #25838).

As a consequence, several old test cases are not accepted anymore
by the compiler since they happened to work accidentally only.
This CL disables parts or all code of those test cases. The issues
are: #18640, #23823, and #24939.

One of the new test cases (fixedbugs/issue27232.go) exposed a
go/types issue. The test case is excluded from the go/types test
suite and an issue was filed (#28576).

Updates #24939.

Nikhil Benesch 402eb45b21 [release-branch.go1.11] runtime: never call into race detector with retaken P
cgocall could previously invoke the race detector on an M whose P had
been retaken. The race detector would attempt to use the P-local state
from this stale P, racing with the thread that was actually wired to
that P. The result was memory corruption of ThreadSanitizer's internal
data structures that presented as hard-to-understand assertion failures
and segfaults.

Reorder cgocall so that it always acquires a P before invoking the race
detector, and add a test that stresses the interaction between cgo and
the race detector to protect against future bugs of this kind.

Fixes #28690.

Robert Griesemer 68ad1d60a2 [release-branch.go1.11] go/types: use correct receiver types for embedded interface methods
Interface methods don't declare a receiver (it's implicit), but after
type-checking the respective *types.Func objects are marked as methods
by having a receiver. For interface methods, the receiver base type used
to be the interface that declared the method in the first place, even if
the method also appeared in other interfaces via embedding. A change in
the computation of method sets for interfaces for Go1.10 changed that
inadvertently, with the consequence that sometimes a method's receiver
type ended up being an interface into which the method was embedded.
The exact behavior also depended on file type-checking order, and because
files are sometimes sorted by name, the behavior depended on file names.

This didn't matter for type-checking (the typechecker doesn't need the
receiver), but it matters for clients, and for printing of methods.

This change fixes interface method receivers at the end of type-checking
when we have all relevant information.

Russ Cox edb6c16b9b [release-branch.go1.11] cmd/go, cmd/link: silence bogus Apple Xcode warning
Certain installations of Xcode are affected by a bug that causes
them to print an inconsequential link-time warning that looks like:

	ld: warning: text-based stub file /System/Library/Frameworks//Security.framework/Security.tbd and library file /System/Library/Frameworks//Security.framework/Security are out of sync. Falling back to library file for linking.

This has nothing to do with Go, and we've sent this repro case
to Apple:

	$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | grep version
	version: 10.0.0.0.1.1535735448
	$ clang --version
	Apple LLVM version 10.0.0 (clang-1000.10.44.2)
	Target: x86_64-apple-darwin17.7.0
	Thread model: posix
	InstalledDir: /Library/Developer/CommandLineTools/usr/bin
	$ cat > issue.c
	int main() { return 0; }
	^D
	$ clang issue.c -framework CoreFoundation
	ld: warning: text-based stub file /System/Library/Frameworks//CoreFoundation.framework/CoreFoundation.tbd and library file /System/Library/Frameworks//CoreFoundation.framework/CoreFoundation are out of sync. Falling back to library file for linking.
	$

Even if Apple does release a fixed Xcode, many people are seeing
this useless warning, and we might as well make it go away.

Fixes #26073.

Keith Randall 3afa9dfa9b [release-branch.go1.11] reflect: ensure correct scanning of return values
During a call to a reflect-generated function or method (via
makeFuncStub or methodValueCall), when should we scan the return
values?

When we're starting a reflect call, the space on the stack for the
return values is not initialized yet, as it contains whatever junk was
on the stack of the caller at the time. The return space must not be
scanned during a GC.

When we're finishing a reflect call, the return values are
initialized, and must be scanned during a GC to make sure that any
pointers in the return values are found and their referents retained.

When the GC stack walk comes across a reflect call in progress on the
stack, it needs to know whether to scan the results or not. It doesn't
know the progress of the reflect call, so it can't decide by
itself. The reflect package needs to tell it.

This CL adds another slot in the frame of makeFuncStub and
methodValueCall so we can put a boolean in there which tells the
runtime whether to scan the results or not.

This CL also adds the args length to reflectMethodValue so the
runtime can restrict its scanning to only the args section (not the
results) if the reflect package says the results aren't ready yet.

Do a delicate dance in the reflect package to set the "results are
valid" bit. We need to make sure we set the bit only after we've
copied the results back to the stack. But we must set the bit before
we drop reflect's copy of the results. Otherwise, we might have a
state where (temporarily) no one has a live copy of the results.
That's the state we were observing in issue #27695 before this CL.

The bitmap used by the runtime currently contains only the args.
(Actually, it contains all the bits, but the size is set so we use
only the args portion.) This is safe for early in a reflect call, but
unsafe late in a reflect call. The test issue27695.go demonstrates
this unsafety. We change the bitmap to always include both args
and results, and decide at runtime which portion to use.

issue27695.go only has a test for method calls. Function calls were ok
because there wasn't a safepoint between when reflect dropped its copy
of the return values and when the caller is resumed. This may change
when we introduce safepoints everywhere.

This truncate-to-only-the-args was part of CL 9888 (in 2015). That
part of the CL fixed the problem demonstrated in issue27695b.go but
introduced the problem demonstrated in issue27695.go.

TODO, in another CL: simplify FuncLayout and its test. stack return
value is now identical to frametype.ptrdata + frametype.gcdata.

Alberto Donizetti c9ca36fb70 [release-branch.go1.11] cmd/compile: prevent overflow in walkinrange
In the compiler frontend, walkinrange indiscriminately calls Int64()
on const CTINT nodes, even though Int64's return value is undefined
for anything over 2⁶³ (in practise, it'll return a negative number).

This causes the introduction of bad constants during rewrites of
unsigned expressions, which make the compiler reject valid Go
programs.

This change introduces a preliminary check that Int64() is safe to
call on the consts on hand. If it isn't, walkinrange exits without
doing any rewrite.
