asn1_ex_i2c actually does have an error condition, it just wasn't being
handled.
628b3c7f2f, imported from upstream's
f3f8e72f494b36d05e0d04fe418f92b692fbb261, tried to check for OID-less
ASN1_OBJECTs and return an error. But it and the upstream change didn't
actually work. -1 in this function means to omit the object, so OpenSSL
was silently misinterpreting the input structure.
This changes the calling convention for asn1_ex_i2c to support this. It
is, unfortunately, a little messy because:
1. One cannot check for object presense without walking the
ASN1_ITEM/ASN1_TEMPLATE structures. You can *almost* check if *pval
is NULL, but ASN1_BOOLEAN is an int with -1 to indicate an omitted
optional. There are also FBOOLEAN/TBOOLEAN types that omit FALSE/TRUE
for DEFAULT. Thus, without more invasive changes, asn1_ex_i2c must be
able to report an omitted element.
2. While the i2d functions report an omitted element by successfully
writing zero bytes, i2c only writes the contents. It thus must
distinguish between an omitted element and an element with
zero-length contents.
3. i2c_ASN1_INTEGER and i2c_ASN1_BIT_STRING return zero on error rather
than -1. Those error paths are not actually reachable because they
only check for NULL. In fact, OpenSSL has even unexported them. But I
found a few callers. Rather than unwind all this and change the
calling convention, I've just made it handle 0 and map to -1 for now.
It's all a no-op anyway, and hopefully we can redo all this with CBB
later.
I've just added an output parameter for now.
In writing tests, I also noticed that the hand-written i2d_ASN1_OBJECT
and i2d_ASN1_BOOLEAN return the wrong value for errors, so I've fixed
that.
Update-Note: A default-constructed object with a required ASN1_OBJECT
field can no longer be encoded without initializing the ASN1_OBJECT.
Note this affects X509: the signature algorithm is an ASN1_OBJECT. Tests
that try to serialize an X509_new() must fill in all required fields.
(Production code is unlikely to be affected because the output was
unparsable anyway, while tests sometimes wouldn't notice.)

Update-Note: An invalid CHOICE object (e.g. GENERAL_NAME) will now fail

This function forgot to handle errors in ASN1_item_ex_i2d. It also
checked x509_name_canon for ret < 0, when x509_name_canon returns a
boolean. For consistency, I've switched to x509_name_encode to return a
boolean as well. It doesn't actually need to return a length because
it's responsible for filling in a->bytes.

tasn_enc.c was missing lots of error checks and mixed up 0 and -1
returns. Document all the internal calling conventions, as best as I can
tell, and fix things up.
There are also error cases it forgets to check (it generally does not
notice missing non-OPTIONAL fields). This CL only addresses errors it
already tries to report. Subsequent CLs will add in the missing error
cases. And then if it all sticks, I'm hoping we can rewrite this with
CBB. Rewriting tsan_dec.c to CBS would also be good, but that will be
more difficult as we need to clear out BER first.
Update-Note: Some error cases which were silently misinterpreted as

Later CLs will clean up the ClientHello construction a bit (draft-12
avoids computing ClientHelloOuter twice). I suspect the transcript
handling on the client can also be simpler, but I'll see what's
convenient after I've changed how ClientHelloOuter is constructed.
Changes of note between draft-10 and draft-13:
- There is now an ECH confirmation signal in both HRR and SH. We don't
actually make much use of this in our client right now, but it
resolves a bunch of weird issues around HRR, including edge cases if
HRR applies to one ClientHello but not the other.
- The confirmation signal no longer depends on key_share and PSK, so we
don't have to work around a weird ordering issue.
- ech_is_inner is now folded into the main encrypted_client_hello code
point. This works better with some stuff around HRR.
- Padding is moved from the padding extension, computed with
ClientHelloInner, to something we fill in afterwards. This makes it
easier to pad up the whole thing to a multiple of 32. I've accordingly
updated to the latest recommended padding construction, and updated
the GREASE logic to match.
- ech_outer_extensions is much easier to process because the order is
required to be consistent. We were doing that anyway, and now a simple
linear scan works.
- ClientHelloOuterAAD now uses an all zero placeholder payload of the
same length. This lets us simplify the server code, but, for now, I've
kept the client code the same. I'll follow this up with a CL to avoid
computing ClientHelloOuter twice.
- ClientHelloOuterAAD is allowed to contain a placeholder PSK. I haven't
filled that in and will do it in a follow-up CL.

V_ASN1_APP_CHOOSE has been discouraged by OpenSSL since 2000:
https://git.openssl.org/gitweb/?p=openssl.git;a=blob;f=CHANGES;h=824f421b8d331ba2a2009dbda333a57493bedb1e;hb=fb047ebc87b18bdc4cf9ddee9ee1f5ed93e56aff#l10848
Instead, upstream recommends an MBSTRING_* constant.
https://www.openssl.org/docs/man1.1.1/man3/X509_NAME_add_entry_by_NID.html
This function is a bit overloaded:
MBSTRING_* means "Decode my input from this format and then re-encode it
using whatever string type best suits the NID (usually UTF8String, but
some NIDs require PrintableString)".
V_ASN1_APP_CHOOSE means "This is a Latin-1 string. Without looking at
the NID, pick one of PrintableString, IA5String, or T61String".
The latter is almost certainly not what callers want. If they want a
particular type, they can always force it by passing a particular
V_ASN1_* constant. This removes the only use of ASN1_PRINTABLE_type
within the library, though there is one external use still.
Update-Note: V_ASN1_APP_CHOOSE is removed. I only found one use, which
has been fixed.

The bulk of RSA_check_key is spent in bn_div_consttime, which is a naive
but constant-time long-division algorithm for the few places that divide
by a secret even divisor: RSA keygen and RSA import. RSA import is
somewhat performance-sensitive, so pick some low-hanging fruit:
The main observation is that, in all but one call site, the bit width of
the divisor is public. That means, for an N-bit divisor, we can skip the
first N-1 iterations of long division because an N-1-bit remainder
cannot exceed the N-bit divisor.
One minor nuisance is bn_lcm_consttime, used in RSA keygen has a case
that does *not* have a public bit width. Apply the optimization there
would leak information. I've implemented this as an optional public
lower bound on num_bits(divisor), which all but that call fills in.

absl::Span, base::span, and std::span have first() and last() methods

Unlike subspan(), they also do not have clipping behavior, so we're

absl::Span::subspan() and is not present in std::span or base::span.

I noticed this while I was reading through the encoder. OpenSSL's ASN.1
library is very sloppy when it comes to reusing enums. It has...
- Universal tag numbers. These are just tag numbers from ASN.1
- utype. These are used in the ASN1_TYPE type field, as well as the
ASN1_ITEM utype fields They are the same as universal tag numbers,
except non-universal types map to V_ASN1_OTHER. I believe ASN1_TYPE
types and ASN1_ITEM utypes are the same, but I am not positive.
- ASN1_STRING types. These are the same as utypes, except V_ASN1_OTHER
appears to only be possible when embedded inside ASN1_TYPE, and
negative INTEGER and ENUMERATED values get mapped to
V_ASN1_NEG_INTEGER and V_ASN1_NEG_ENUMERATED. Additionally, some
values like V_ASN1_OBJECT are possible in a utype but not possible in
an ASN1_STRING (and will cause lots of problems if ever placed in
one).
- Sometimes one of these enums is augmented with V_ASN1_UNDEF and/or
V_ASN1_APP_CHOOSE for extra behaviors.
- Probably others I'm missing.
These get mixed up all the time. asn1_ex_i2c's MSTRING path converts
from ASN1_STRING type to utype and forgets to normalize V_ASN1_NEG_*.
This means that negative INTEGERs and ENUMERATEDs in MSTRINGs do not get
encoded right.
The negative INTEGER case is unreachable (unless the caller passes
the wrong ASN1_STRING to an MSTRING i2d function, but mismatching i2d
functions generally does wrong things), but the negative ENUMERATED case
is reachable. Fix this and add a test.

In writing the tests, I noticed that the documentation was wrong. First,
the maximum lengths are measured in codepoints, not bytes.
Second, the TODO was wrong. We actually do handle this correctly,
*almost*. Rather, the bug is that the function assumes |mask| contains
no extraneous bits. If it does, all extraneous bits are interpreted as
B_ASN1_UTF8STRING. This seems like a bug, so I've gone ahead and fixed
that, with a test.

ASN1_TFLG_SET_ORDER was used in OpenSSL's CMS and PKCS#7
implementations, which we've removed. Fields that use it not only get
the DER SET sorting but, when serialized, go back and mutate the
original object to match.
This is unused, so remove it. This removes one of the sources of
non-const behavior in i2d functions.

ASN1_STRING and ASN1_TYPE type values almost line up, but not quite.
Negative INTEGERs are not possible in X509_NAME (tag2bit maps INTEGER to
0), but negative ENUMERATEDs are (tag2bit maps ENUMERATED to
B_ASN1_UNKNOWN). See https://crbug.com/boringssl/412 for some notes on
this mess. Either way, the library will freely produce ASN1_STRING
INTEGERs and ENUMERATEDs in non-MSTRING contexts, so get this case
right.
