On reflection, I think we'll need to note whether dummy PQ padding was
echoed on a given connection. Otherwise measurements in Chrome will be
mixed with cases where people have MITM proxies that ignored the
extension, or possibly Google frontends that haven't been updated.
Therefore this change will be used to filter latency measurements in
Chrome to only include those where the extension was echoed and we'll
measure at levels of 1 byte (for control), 400 bytes, and 1100 bytes.
This also makes it an error if the server didn't echo an extension of
the same length as was sent.

SSLv3_method, SSLv3_client_method, and SSLv3_server_method produce
SSL_CTXs which fail every handshake. They appear no longer necessary for

SSLv3 is still accessible to callers who explicitly re-enable SSLv3 on a

Meanwhile, clear out a weird hack we had here.
Update-Note: I believe there are no more callers of these functions. Any
that were were already non-functional as these methods haven't been

OpenSSL's RSA API is poorly designed and does not have a single place to
properly initialize the key. See
https://github.com/openssl/openssl/issues/5158.
To workaround this flaw, we must lazily instantiate pre-computed
Montgomery bits with locking. This is a ton of complexity. More
importantly, it makes it very difficult to implement RSA without side
channels. The correct in-memory representation of d, dmp1, and dmq1
depend on n, p, and q, respectively. (Those values have private
magnitudes and must be sized relative to the respective moduli.)
08805fe279 attempted to fix up the various
widths under lock, when we set up BN_MONT_CTX. However, this introduces
threading issues because other threads may access those exposed
components (RSA_get0_* also count as exposed for these purposes because
they are get0 functions), while a private key operation is in progress.
Instead, we do the following:
- There is no actual need to minimize n, p, and q, but we have minimized
copies in the BN_MONT_CTXs, so use those.
- Store additional copies of d, dmp1, and dmq1, at the cost of more
memory used. These copies have the correct width and are private,
unlike d, dmp1, and dmq1 which are sadly exposed. Fix private key
operations to use them.
- Move the frozen bit out of rsa->flags, as that too was historically
accessible without locking.
(Serialization still uses the original BIGNUMs, but the RSAPrivateKey
serialization format already inherently leaks the magnitude, so this
doesn't matter.)

This is a bit easier to read than BN_less_than_consttime when we must do

Alas, the existence of RSA keys with q > p is obnoxious, but we can
canonicalize it away. To my knowledge, the remaining leaks in RSA are:
- Key generation. This is kind of hopelessly non-constant-time but
perhaps deserves a more careful ponder. Though hopefully it does not
come in at a measurable point for practical purposes.
- Private key serialization. RSAPrivateKey inherently leaks the
magnitudes of d, dmp1, dmq1, and iqmp. This is unavoidable but
hopefully does not come in at a measurable point for practical
purposes.
- If p and q have different word widths, we currently fall back to the
variable-time BN_mod rather than Montgomery reduction at the start of
CRT. I can think of ways to apply Montgomery reduction, but it's
probably better to deny CRT to such keys, if not reject them outright.
- bn_mul_fixed and bn_sqr_fixed which affect the Montgomery
multiplication bn_mul_mont-less configurations, as well as the final
CRT multiplication. We should fix this.

d, dmp1, dmq1, and iqmp have private magnitudes. This is awkward because
the RSAPrivateKey serialization leaks the magnitudes. Do the best we can
and fix them up before any RSA operations.
This moves the piecemeal BN_MONT_CTX_set_locked into a common function
where we can do more complex canonicalization on the keys. Ideally this
would be done on key import, but the exposed struct (and OpenSSL 1.1.0's
bad API design) mean there is no single point in time when key import is
finished.
Also document the constraints on RSA_set0_* functions. (These
constraints aren't new. They just were never documented before.)
Update-Note: If someone tried to use an invalid RSA key where d >= n,
dmp1 >= p, dmq1 >= q, or iqmp >= p, this may break. Such keys would not
have passed RSA_check_key, but it's possible to manually assemble
keys that bypass it.

Give a non-minimal modulus, there are two possible values of R we might
pick: 2^(BN_BITS2 * width) or 2^(BN_BITS2 * bn_minimal_width).
Potentially secret moduli would make the former attractive and things
might even work, but our only secret moduli (RSA) have public bit
widths. It's more cases to test and the usual BIGNUM invariant is that
widths do not affect numerical output.
Thus, settle on minimizing mont->N for now. With the top explicitly made

The private key callback may not push one of its own (it's possible to

completely wrong, as "syscall" really means "I don't know, something you

but most callers just check errno. And indeed cert_cb pushes its own
error, so this probably should as well.
Update-Note: Custom private key callbacks which push an error code on
failure will report both that error followed by
SSL_R_PRIVATE_KEY_OPERATION_FAILED. Callbacks which did not push any

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.

This would remove the extra level of indirection in Chromium

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.)

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

with reversed roles.)
However, it appears that Cisco devices have non-compliant TLS 1.2

Hopefully they are the only ones doing this. Implement a

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 newer clang-cl is unhappy about the tautological comparison on
Windows, but the comparison itself is unnecessary anyway, since the
values will never exceed uint32_t.
I think the reason it's not firing elsewhere is because on other 64-bit
platforms, it is not tautological because long is 64-bit. On other
32-bit platforms, I'm not sure we actually have a standalone trunk clang
builder right now.
Update-Note: UTF8_getc and UTF8_putc were unexported. No one appears to
be calling them. (We're a crypto library, not a Unicode library.)

We can probably do this globally at this point since the cipher
requirements are much more restrict than they were in the beginning.
(Firefox, in particular, has done so far a while.) For now add a flag
since some consumer wanted this.
I'll see about connecting it to a Chrome field trial after our breakage
budget is no longer reserved for TLS 1.3.

This reverts commit 66801feb17. This
turned out to break a lot more than expected. Hopefully we can reland it
soon, but we need to fix up some consumers first.
Note due to work that went in later, this is not a trivial revert and
should be re-reviewed.

We need it in both directions. Also I missed that in OBJ_obj2txt we
allowed uint64_t components, but in my new OBJ_txt2obj we only allowed
uint32_t. For consistency, upgrade that to uint64_t.

OBJ_txt2obj is currently implemented using BIGNUMs which is absurd. It
also depends on the giant OID table, which is undesirable. Write a new
one and expose the low-level function so Chromium can use it without the
OID table.
