BN_mod_sqrt implements the Tonelli–Shanks algorithm, which requires a
prime modulus. It was written such that, given a composite modulus, it
would sometimes loop forever. This change fixes the algorithm to always
terminate. However, callers must still pass a prime modulus for the
function to have a defined output.
In OpenSSL, this loop resulted in a DoS vulnerability, CVE-2022-0778.
BoringSSL is mostly unaffected by this. In particular, this case is not
reachable in BoringSSL from certificate and other ASN.1 elliptic curve
parsing code. Any impact in BoringSSL is limited to:
- Callers of EC_GROUP_new_curve_GFp that take untrusted curve parameters
- Callers of BN_mod_sqrt that take untrusted moduli
This CL updates documentation of those functions to clarify that callers
should not pass attacker-controlled values. Even with the infinite loop
fixed, doing so breaks preconditions and will give undefined output.

This fixes several issues around ASN1_INTEGER handling. First, invalid
INTEGERs (not allowed in BER or DER) will no longer be accepted by
d2i_ASN1_INTEGER. This aligns with upstream OpenSSL, which became strict
in 6c5b6cb035666d46495ccbe4a4f3d5e3a659cd40, part of OpenSSL 1.1.0.
In addition to matching the standard, this is needed to avoid
round-tripping issues: ASN1_INTEGER uses a sign-and-magnitude
representation, different from the DER two's complement representation.
That means we cannot represent invalid DER INTEGERs. Attempting to do so
messes up some invariants and causes values to not round-trip correctly
when re-encoded. Thanks to Tavis Ormandy for catching this.
Next, this CL tidies the story around invalid ASN1_INTEGERs (non-minimal
and negative zero). Although we will never produce them in parsing, it
is still possible to manually construct them with ASN1_STRING APIs.
Historically (CVE-2016-2108), it was possible to get them out of the
parser, due to a different bug, *and* i2d_ASN1_INTEGER had a memory
error in doing so. That different bug has since been fixed, but we
should still handle them correctly and test this. (To that end, this CL
adds a test we ought to have added importing upstream's
3661bb4e7934668bd99ca777ea8b30eedfafa871 back in
c4eec0c16b02c97a62a95b6a08656c3a9ddb6baa.)
As the two's complement invariants are subtle as it is, I've opted to
just fix the invalid values before encoding. However, invalid
ASN1_INTEGERs still do not quite work right because ASN1_INTEGER_get,
ASN1_INTEGER_cmp, and ASN1_STRING_cmp will all return surprising values
with them. I've left those alone.
Finally, that leads to the zero value. Almost every function believes
the representation of 0 is a "\0" rather than "". However, a
default-constructed INTEGER, like any other string type, is "". Those do
not compare as equal. crypto/asn1 treats ASN1_INTEGER generically as
ASN1_STRING enough that I think changing the other functions to match is
cleaner than changing default-constructed ASN1_INTEGERs. Thus this CL
removes all the special cases around zero.
Update-Note: Invalid INTEGERs will no longer parse, but they already
would not have parsed in OpenSSL. Additionally, zero is now internally
represented as "" rather than "\0".

that mixed them up would get the right answer on positive values and
silently misinterpret the input on negative values. This change matches

This extends the old ASN1_INTEGER_set tests to cover all integers. There

single set of BIGNUM-based test vectors.
Notably, this test now covers:

- ASN1_INTEGER_get, not just ASN1_INTEGER_set
- BIGNUM conversions
- ASN1_INTEGER_cmp

Although the preceding CL fixes x509v3_bytes_to_hex to work with the
empty string, it's not really a good representation for zero. Zero as an
ASN1_INTEGER is sometimes the empty string (default-constructed) and
sometimes a single zero byte (parsed). bytes_to_hex also doesn't capture
the sign bit.
Instead, use X509V3_add_value_int, matching most of the other i2v, etc.,
functions in crypto/x509v3. X509V3_add_value_int calls i2s_ASN1_INTEGER,
which prints small values in decimal and large values in hexadecimal
with a 0x prefix.
It is unclear to me whether i2v and v2i are generally expected to be
inverses. i2v (or i2s or i2r) is used when printing an extension, while
v2i is used when using the stringly-typed config file APIs. However,
i2v_AUTHORITY_KEYID does not consume the "serial" key at all. It
computes the serial from the issuer cert.
Oddly, there is one ASN1_INTEGER,
PROXY_CERT_INFO_EXTENSION.pcPathLengthConstraint, which uses
i2a_ASN1_INTEGER instead. That one uses hexadecimal without the "0x"
prefix, and with newlines. Interestingly, its r2i function is not the
reverse of i2r and parses the s2i_ASN1_INTEGER format.
Between those, I'm assuming they're not necessarily invertible.

Now we only have one BER/DER TLV parser. Annoyingly, this uses the CBS

allow a non-minimal length in certificate signature fields (see

For now, this CL calls CBS_get_any_ber_asn1_element. This is still an
improvement over the old parser because we'll reject non-minimal tags
(which are actually even forbidden in BER). Later, we should move the
special case to just the signature field, and ultimately to a
preprocessing step specific to that part of Android.
Update-Note: Invalid certificates (and the few external structures using

Having to check for header_len == len and a last byte of 0x80 is
actually unambiguous, but not obvious. Before we supported multi-byte
tags, a two-byte header was always {tag, 0x80}, but now a three-byte
header could be {tag1, tag2, 0x80}. But a 0x80 suffix could also be
{tag, 0x81, 0x80} for a 128-byte definite-length element.
This is unambiguous because header_len == len implies either zero length
or indefinite-length, and it is not possible to encode a definite length
of zero, in BER or DER, with a header that ends in 0x80. Still, rather
than go through all this, we can just report indefinite lengths to the
caller directly.
Update-Note: This is a breaking change to CBS_get_any_ber_asn1_element.
There is only one external caller of this function, and it should be
possible to fix them atomically with this change, so I haven't bothered
introducing another name, etc. (See cl/429632075 for the fix.)

On Arm, our CRYPTO_is_*_capable functions check the corresponding
preprocessor symbol. This allows us to automatically drop dynamic checks
and fallback code when some capability is always avilable.
This CL does the same on x86, as well as consolidates our
OPENSSL_ia32cap_P checks in one place. Since this abstraction is
incompatible with some optimizations we do around OPENSSL_ia32cap_get()
in the FIPS module, I've marked the symbol __attribute__((const)), which
is enough to make GCC and Clang do the optimizations for us. (We already
do the same to DEFINE_BSS_GET.)
Most x86 platforms support a much wider range of capabilities, so this
is usually a no-op. But, notably, all x86_64 Mac hardware has SSSE3
available, so this allows us to statically drop an AES implementation.
(On macOS with -Wl,-dead_strip, this seems to trim 35080 bytes from the
bssl binary.) Configs like -march=native can also drop a bunch of code.
Update-Note: This CL may break build environments that incorrectly mark
some instruction as statically available. This is unlikely to happen
with vector instructions like AVX, where the compiler could freely emit
them anyway. However, instructions like AES-NI might be set incorrectly.

FIPS validation requires showing that the continuous and start-up tests
are effective by breaking them. Traditionally BoringSSL used #defines
that tweaked the expected values. However, 140-3 now requires that the
inputs be changed, not the expected outputs.
Also, the number of tests is going to increase. Since slower platforms
already took too long to compile BoringSSL n times (once for each test
to break) we want something faster too.
Therefore all the known-answer tests (KATs) are changed such that a Go
program can find and replace the input value in order to break them.
Thus we only need to recompile once to disable the integrity test.
The runtime tests still need a #define to break, but that #define is now
put in a header file so that only the module need be recompiled, not
everything as in the previous system.

https://boringssl-review.googlesource.com/c/boringssl/+/51265 broke
Linux and macOS platforms on architectures where we don't build
assembly. OPENSSL_NO_ASM needs to match the assembly selector.
While I'm here, remove the OPENSSL_C11_ATOMIC comment. We autodetect
atomics these days, so the flag is only useful if you want to force it.

In testing out the ECH bits on the Chromium side, it is much harder to
tell what's going on without some indication that we sent a
ClientHelloInner. This CL routes it into the callback. A corresponding
CL in Chromium will add it to NetLog.

Both call sites end up calling them in succession. This saves a little
bit of code.

The ECH extension is not covered in the AAD and so should not be
referenced in ech_outer_extensions. We end up rejecting this anyway when
checking for valid ClientHelloInners, but better to reject this
explicitly, as the spec suggests.
As part of this, use the more specific error in the various tests, so we
can distinguish the two cases. (DECODE_ERROR is coming from an extra,
probably unnecessary, error in ssl_decode_client_hello_inner's caller.)
