ssl23_get_client_hello has lots of remnants of SSLv2 support and remnants of an
even older SSL_OP_NON_EXPORT_FIRST option (see upstream's
d92f0bb6e9ed94ac0c3aa0c939f2565f2ed95935) which complicates the logic.
Split it into three states and move V2ClientHello parsing into its own
function. Port it to CBS and CBB to give bounds checks on the V2ClientHello
parse.
This fixes a minor bug where, if the SSL_accept call in ssl23_get_client_hello
failed, cb would not be NULL'd and SSL_CB_ACCEPT_LOOP would get reported an
extra time.
It also unbreaks the invariant between s->packet, s->packet_length,
s->s3->rbuf.buf, and s->s3->rbuf.offset at the point the switch, although this
was of no consequence because the first ssl3_read_n call passes extend = 0
which resets s->packet and s->packet_length.
It also makes us tolerant to major version bumps in the ClientHello. Add tests
for TLS tolerance of both minor and major version bumps as well as the HTTP
request error codes.

This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.
On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h
In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.
In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

Compilers have a bad habit of removing "superfluous" memset calls that
are trying to zero memory. For example, when memset()ing a buffer and
then free()ing it, the compiler might decide that the memset is
unobservable and thus can be removed.
Previously we tried to stop this by a) implementing memset in assembly
on x86 and b) putting the function in its own file for other platforms.
This change removes those tricks in favour of using asm directives to
scare the compiler away. As best as our compiler folks can tell, this is
sufficient and will continue to be so.

This change adds the stitched RC4-MD5 code from upstream OpenSSL but
exposes it as an AEAD. It's not a normal AEAD (it's stateful thus
doesn't take an nonce) but forcing pre-AEAD cipher suites in the AEAD
interface is less painful than forcing AEADs into the EVP_CIPHER
interface. Over time, more and more cipher suites will be exposed as
TLS-specific AEADs and then ssl/ can drop support for EVP_CIPHER.

Fixes one comment that mentioned the wrong function name. Also causes
two BN random functions to fail when the output is NULL. Previously they
would silently do nothing.

Since all AEAD ciphers now go through EVP_AEAD interface, the code which
uses EVP_Cipher interface no longer needs any of AEAD handling logic.
This also removes EVP_CTRL_AEAD_TLS1_AAD from GCM interface, which was
duplicating non-TLS-specific GCM logic and is not used anymore.

aead_test reads test vectors from a file but used blank lines to
indicate the end of a test case. If the file ended without a blank line
to terminate the final test case, it would previously have been skipped.

Apart from the obvious little issues, this also works around a
(seeming) libtool/linker:
a.c defines a symbol:
int kFoo;
b.c uses it:
extern int kFoo;
int f() {
return kFoo;
}
compile them:
$ gcc -c a.c
$ gcc -c b.c
and create a dummy main in order to run it, main.c:
int f();
int main() {
return f();
}
this works as expected:
$ gcc main.c a.o b.o
but, if we make an archive:
$ ar q lib.a a.o b.o
and use that:
$ gcc main.c lib.a
Undefined symbols for architecture x86_64
"_kFoo", referenced from:
_f in lib.a(b.o)
(It doesn't matter what order the .o files are put into the .a)
Linux and Windows don't seem to have this problem.
nm on a.o shows that the symbol is of type "C", which is a "common symbol"[1].
Basically the linker will merge multiple common symbol definitions together.
If ones makes a.c read:
int kFoo = 0;
Then one gets a type "D" symbol - a "data section symbol" and everything works
just fine.
This might actually be a libtool bug instead of an ld bug: Looking at `xxd
lib.a | less`, the __.SYMDEF SORTED index at the beginning of the archive
doesn't contain an entry for kFoo unless initialised.

Now that the consuming code in ssl/ is removed, there is no need for this.
Leave SSL_COMP and STACK_OF(SSL_COMP) for now so as not to break any code which

compression.

Previously we generated a number that was 8 bytes too large and used a
modular reduction, which has a (tiny, tiny) bias towards zero.
Out of an excess of caution, instead truncate the generated nonce and
try again if it's out of range.

Ensure the library can find the right files under /etc/ssl/certs when
running on older systems.
There are many symbolic links under /etc/ssl/certs created by using
hash of the PEM certificates in order for OpenSSL to find those
certificates. Openssl has a tool to help you create hash symbolic
links (tools/c_rehash). However newer versions of the library changed
the hash algorithm, which makes it unable to run properly on systems
that use the old /etc/ssl/certs layout (e.g. Ubuntu Lucid).
This patch gives a way to find a certificate according to its hash by
using both the old and new algorithms. http://crbug.com/111045 is used
to track this issue.

A client reference identity of ".example.com" matches a server certificate
presented identity that is any sub-domain of "example.com" (e.g.
"www.sub.example.com).
With the X509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS flag, it matches only direct
child sub-domains (e.g. "www.sub.example.com"). (cherry picked from commit

The lazy-initialisation of BN_MONT_CTX was serialising all threads, as noted by
Daniel Sands and co at Sandia. This was to handle the case that 2 or more
threads race to lazy-init the same context, but stunted all scalability in the
case where 2 or more threads are doing unrelated things! We favour the latter
case by punishing the former. The init work gets done by each thread that finds
the context to be uninitialised, and we then lock the "set" logic after that
work is done - the winning thread's work gets used, the losing threads throw
away what they've done.

This is used to avoid some timing leaks in RSA decryption.
Fix a bug in handling of 128 byte long PSK identity in
psk_client_callback.
OpenSSL supports PSK identities of up to (and including) 128 bytes in
length. PSK identity is obtained via the psk_client_callback,
implementors of which are expected to provide a NULL-terminated
identity. However, the callback is invoked with only 128 bytes of
storage thus making it impossible to return a 128 byte long identity and
the required additional NULL byte.
This CL fixes the issue by passing in a 129 byte long buffer into the
psk_client_callback. As a safety precaution, this CL also zeroes out the
buffer before passing it into the callback, uses strnlen for obtaining
the length of the identity returned by the callback, and aborts the
handshake if the identity (without the NULL terminator) is longer than
128 bytes.

Previously, this input to the base64 code:
================================================================================-
Would cause the output length of EVP_DecodeUpdate to be negative. When
that happened in the base64 BIO, it would crash. In PEM decoding, the
ASN.1 code actually maintains signed lengths and manages to simply error
out!
Fix handling of points at infinity in ec_GFp_simple_points_make_affine.
When inverting an array of Z coordinates, the algorithm is supposed to
treat any 0 essentially like a 1 to remain in the multiplicative group;
however, for one of the cases, we incorrectly multiplied by 0 and thus
ended up with garbage.
This change adjusts the stack pointer during CBC decryption. The code
was previously using the red zone across function calls and valgrind
thinks that the "unused" stack is undefined after a function call.
Some RSA private keys are specified with only n, e and d. Although we
can use these keys directly, it's nice to have a uniform representation
that includes the precomputed CRT values. This change adds a function
that can recover the primes from a minimal private key of that form.
This change saves several EC routines from crashing when an EC_KEY is
missing a public key. The public key is optional in the EC private key
format and, without this patch, running the following through `openssl
ec` causes a crash:
-----BEGIN EC PRIVATE KEY-----
MBkCAQEECAECAwQFBgcIoAoGCCqGSM49AwEH
-----END EC PRIVATE KEY-----
Ensure that, when generating small primes, the result is actually of the
requested size. Fixes OpenSSL #2701.
This change does not address the cases of generating safe primes, or
where the |add| parameter is non-NULL.
(The issue was reported by Shay Gueron.)
The final reduction in Montgomery multiplication computes if (X >= m) then X =
X - m else X = X
In OpenSSL, this was done by computing T = X - m, doing a constant-time
selection of the *addresses* of X and T, and loading from the resulting
address. But this is not cache-neutral.
This patch changes the behaviour by loading both X and T into registers, and
doing a constant-time selection of the *values*.
TODO(fork): only some of the fixes from the original patch still apply to
