    cryptobyte: fix panic due to malformed ASN.1 inputs on 32-bit archs

    When int is 32 bits wide (on 32-bit architectures like 386 and arm), an
    overflow could occur, causing a panic, due to malformed ASN.1 being
    passed to any of the ASN1 methods of String.

    Tested on linux/386 and darwin/amd64.

    This fixes CVE-2020-7919 and was found thanks to the Project Wycheproof
    test vectors.

An attacker can trick the Windows system verifier to use a poisoned set
of elliptic curve parameters for a trusted root, allowing it to generate
spoofed signatures. When this happens, the returned chain will present
the unmodified original root, so the actual signatures won't verify (as
they are invalid for the correct parameters). Simply double check them
as a safety measure and mitigation.

Windows users should still install the system security patch ASAP.

This is the same mitigation adopted by Chromium:

Commit e0cf3de987e6 of the vcs-test.golang.org/git/querytest repo
includes a go.mod file specifying path vcs-test.golang.org/git/querytest.git,
as does the latest commit. Since the repository also lacks v3 tags,
a query for "latest" with a v3 path should fail.

Due to a bug, that query does not fail as expected with Go 1.12.
However, we do not need to continue to test for buggy behavior that
was fixed in a subsequent release.

If a pointer write is not atomic, if the GC is running
concurrently, it may observe a partially updated pointer, which
may point to unallocated or already dead memory. Most pointer
writes, like the store instructions generated by the compiler,
are already atomic. But we still need to be careful in places
like memmove. In memmove, we don't know which bits are pointers
(or too expensive to query), so we ensure that all aligned
pointer-sized units are written atomically.

[release-branch.go1.12] runtime: do not use PowerRegisterSuspendResumeNotification on systems with "program time" timer

Systems where PowerRegisterSuspendResumeNotification returns ERROR_
FILE_NOT_FOUND are also systems where nanotime() is on "program time"
rather than "real time".  The chain for this is:

powrprof.dll!PowerRegisterSuspendResumeNotification ->
  umpdc.dll!PdcPortOpen ->
    ntdll.dll!ZwAlpcConnectPort("\\PdcPort") ->
      syscall -> ntoskrnl.exe!AlpcpConnectPort

Opening \\.\PdcPort fails with STATUS_OBJECT_NAME_NOT_FOUND when pdc.sys
hasn't been initialized. Pdc.sys also provides the various hooks for
sleep resumption events, which means if it's not loaded, then our "real
time" timer is actually on "program time". Finally STATUS_OBJECT_NAME_
NOT_FOUND is passed through RtlNtStatusToDosError, which returns ERROR_
FILE_NOT_FOUND. Therefore, in the case where the function returns ERROR_
FILE_NOT_FOUND, we don't mind, since the timer we're using will
correspond fine with the lack of sleep resumption notifications. This
applies, for example, to Docker users.

If a compilation has multiple text sections, code in
textOff must compare the offset argument against the range
for each text section to determine which one it is in.
The comparison looks like this:

if uintptr(off) >= sectaddr && uintptr(off) <= sectaddr+sectlen

If the off value being compared is equal to sectaddr+sectlen then it
is not within the range of the text section but after it. The
comparison should be just '<'.

Starting with macOS 10.15 (Catalina), Apple now requires all software
distributed outside of the App Store to be notarized. Any binaries we
distribute must abide by a strict set of requirements like code-signing
and having a minimum target SDK of 10.9 (amongst others).

Apple’s notarization service will recursively inspect archives looking to
find notarization candidate binaries. If it finds a binary that does not
meet the requirements or is unable to decompress an archive, it will
reject the entire distribution. From cursory testing, it seems that the
service uses content sniffing to determine file types, so changing
the file extension will not work.

There are some binaries and archives included in our distribution that
are being detected by Apple’s service as potential candidates for
notarization or decompression. As these are files used by tests and some
are intentionally invalid, we don’t intend to ever make them compliant.

As a workaround for this, we base64-encode any binaries or archives that
Apple’s notarization service issues a warning for, as these warnings will
become errors in January 2020.
