In order to process some NIST FAX files, we needed to implement a custom
scanner function to skip over lines that are effectively comments, but
not marked as such.
In the near future we'll need to process KAS FAX files, for which we
need not only to skip over unmarked comment lines, but also to skip some
lines of the response which the FAX doesn't include.
For this we need a more powerful callback function, which this change
provides.

This extension will be used to measure the latency impact of potentially
sending a post-quantum key share by default. At this time it's purely
measuring the impact of the client sending the key share, not the server
replying with a ciphertext.
We could use the existing padding extension for this but that extension
doesn't allow the server to echo it, so we would need a different
extension in the future anyway. Thus we just create one now.
We can assume that modern clients will be using TLS 1.3 by the time that
PQ key-exchange is established and thus the key share will be sent in
all ClientHello messages. However, since TLS 1.3 isn't quite here yet,
this extension is also sent for TLS 1.0–1.2 ClientHellos. The latency
impact should be the same either way.

The Chromium certificate verifier ends up encoding a SET OF when
canonicalizing X.509 names. Requiring the caller canonicalize a SET OF
is complicated enough that we should probably sort it for folks. (We
really need to get this name canonicalization insanity out of X.509...)
This would remove the extra level of indirection in Chromium
net/cert/internal/verify_name_match.cc CBB usage.
Note this is not quite the same order as SET, but SET is kind of
useless. Since it's encoding heterogeneous values, it is reasonable to
require the caller just encode them in the correct order. In fact, a DER
SET is just SEQUENCE with a post-processing step on the definition to
fix the ordering of the fields. (Unless the SET contains an untagged
CHOICE, in which case the ordering is weird, but SETs are not really
used in the real world, much less SETs with untagged CHOICEs.)

This is a reland of https://boringssl-review.googlesource.com/2330. I

Android's attestion format uses some ludicrously large tag numbers:
https://developer.android.com/training/articles/security-key-attestation.html#certificate_schema
Add support for these in CBS/CBB. The public API does not change for
callers who were using the CBS_ASN1_* constants, but it is no longer the
case that tag representations match their DER encodings for small tag
numbers. When passing tags into CBS/CBB, use CBS_ASN1_* constants. When
working with DER byte arrays (most commonly test vectors), use the
numbers themselves.

Update-Note: The in-memory representation of CBS/CBB tags changes.
Additionally, we now support tag numbers above 30. I believe I've now
actually cleared the fallout of the former. There is one test in
Chromium and the same test in the internal repository that needs
fixing.

Instead, require that callers configure the group before setting either
half of the keypair. Additionally, reject EC_KEY_set_group calls that
change the group. This will simplify clearing one more BIGNUM timing
leak.

TLS 1.3 includes a server-random-based anti-downgrade signal, as a
workaround for TLS 1.2's ServerKeyExchange signature failing to cover
the entire handshake. However, because TLS 1.3 draft versions are each
doomed to die, we cannot deploy it until the final RFC. (Suppose a
draft-TLS-1.3 client checked the signal and spoke to a final-TLS-1.3
server. The server would correctly negotiate TLS 1.2 and send the
signal. But the client would then break. An anologous situation exists
with reversed roles.)
However, it appears that Cisco devices have non-compliant TLS 1.2
implementations[1] and copy over another server's server-random when
acting as a TLS terminator (client and server back-to-back).
Hopefully they are the only ones doing this. Implement a
measurement-only version with a different value. This sentinel must not
be enforced, but it will tell us whether enforcing it will cause
problems.

The first step of RSA with the CRT optimization is to reduce our input
modulo p and q. We can do this in constant-time[*] with Montgomery
reduction. When p and q are the same size, Montgomery reduction's bounds
hold. We need two rounds of it because the first round gives us an
unwanted R^-1.
This does not appear to have a measurable impact on performance. Also
add a long TODO describing how to make the rest of the function
constant-time[*] which hopefully we'll get to later. RSA blinding should
protect us from it all, but make this constant-time anyway.
Since this and the follow-up work will special-case weird keys, add a

breaking them intentionally someday...)

Originally, the only OpenSSL API to stringify errors was:
char *ERR_error_string(unsigned long e, char *buf);
This API leaves callers a choice to either be thread unsafe (buf = NULL)
or pass in a buffer with unknown size. Indeed the original
implementation was just a bunch of unchecked sprintfs with, in the buf =
NULL case, a static 256-byte buffer.
388f2f56f2/crypto/err/err.c (L374)
Then ERR_error_string was documented that the buffer must be size 120.
Nowhere in the code was 120 significant. I expect OpenSSL just made up a
number.
388f2f56f2
Then upstream added the ERR_error_string_n API. Although the
documentation stated 120 bytes, the internal buffer was 256, so the code
actually translates ERR_error_string to ERR_error_string_n(e, buf, 256),
not ERR_error_string_n(e, buf, 120)!
e5c84d5152
So the documentation was wrong all this time! OpenSSL 1.1.0 corrected
the documentation to 256, but, alas, a lot of code used the
documentation and sized the buffer at 120. We should fix all
ERR_error_string callers to ERR_error_string_n but, in the meantime,
using 120 is probably less effort.
Note this also affects ERR_print_errors_cb right now. We don't have
function codes, so 120 bytes leaves 60 bytes for the reason code. Our
longest one, TLS_PEER_DID_NOT_RESPOND_WITH_CERTIFICATE_LIST is 46 bytes,
so it's a little tight, but, if needed, we can recover 20-ish bytes by
shrinking the library names. We can also always make ERR_print_errors_cb
use a larger buffer.

The third-party toolchain file doesn't actually work with newer NDKs,
and the one shipped with the NDK has fewer bugs.

This makes it difficult to build against the NDK's toolchain file. The
problem is __clang__ just means Clang is the frontend and implies
nothing about which assembler. When using as, it is fine. When using
clang-as on Linux, one needs a clang-as from this year.
The only places where we case about clang's integrated assembler are iOS
(where perlasm strips out .arch anyway) and build environments like
Chromium which have a regularly-updated clang. Thus we can remove this
now.
Bug: 39
Update-Note: Holler if this breaks the build. If it doesn't break the
build, you can probably remove any BORINGSSL_CLANG_SUPPORTS_DOT_ARCH
or explicit -march armv8-a+crypto lines in your BoringSSL build.
