Ryan Houdek a48e284317 Update external polarssl to 1.3.8
There were some fixes back on March 13th, 2014 for fixing compiling on MIPS64.
Also some fixes on June 25th, 2014 for SPARC64 fixes.

Probably more things, but those are what I care about.

PolarSSL ChangeLog (Sorted per branch, date)
= PolarSSL 1.3.8 released 2014-07-11
Security
* Fix length checking for AEAD ciphersuites (found by Codenomicon).
It was possible to crash the server (and client) using crafted messages
when a GCM suite was chosen.
Features
* Add CCM module and cipher mode to Cipher Layer
* Support for CCM and CCM_8 ciphersuites
* Support for parsing and verifying RSASSA-PSS signatures in the X.509
modules (certificates, CRLs and CSRs).
* Blowfish in the cipher layer now supports variable length keys.
* Add example config.h for PSK with CCM, optimized for low RAM usage.
* Optimize for RAM usage in example config.h for NSA Suite B profile.
* Add POLARSSL_REMOVE_ARC4_CIPHERSUITES to allow removing RC4 ciphersuites
from the default list (inactive by default).
* Add server-side enforcement of sent renegotiation requests
(ssl_set_renegotiation_enforced())
* Add SSL_CIPHERSUITES config.h flag to allow specifying a list of
ciphersuites to use and save some memory if the list is small.
Changes
* Add LINK_WITH_PTHREAD option in CMake for explicit linking that is
required on some platforms (e.g. OpenBSD)
* Migrate zeroizing of data to polarssl_zeroize() instead of memset()
against unwanted compiler optimizations
* md_list() now returns hashes strongest first
* Selection of hash for signing ServerKeyExchange in TLS 1.2 now picks
strongest offered by client.
* All public contexts have _init() and _free() functions now for simpler
usage pattern
Bugfix
* Fix in debug_print_msg()
* Enforce alignment in the buffer allocator even if buffer is not aligned
* Remove less-than-zero checks on unsigned numbers
* Stricter check on SSL ClientHello internal sizes compared to actual packet
size (found by TrustInSoft)

* Other minor issues (found by Peter Vaskovic)
* Fix symlink command for cross compiling with CMake (found by Andre
Heinecke)
* Fix DER output of gen_key app (found by Gergely Budai)
* Very small records were incorrectly rejected when truncated HMAC was in
use with some ciphersuites and versions (RC4 in all versions, CBC with
versions < TLS 1.1).
* Very large records using more than 224 bytes of padding were incorrectly
rejected with CBC-based ciphersuites and TLS >= 1.1
* Very large records using less padding could cause a buffer overread of up
to 32 bytes with CBC-based ciphersuites and TLS >= 1.1
* Restore ability to use a v1 cert as a CA if trusted locally. (This had
been removed in 1.3.6.)
* Restore ability to locally trust a self-signed cert that is not a proper
CA for use as an end entity certificate. (This had been removed in
1.3.6.)
* Fix preprocessor checks for bn_mul PPC asm (found by Barry K. Nathan).
* Use \n\t rather than semicolons for bn_mul asm, since some assemblers
interpret semicolons as comment delimiters (found by Barry K. Nathan).
* Fix off-by-one error in parsing Supported Point Format extension that
caused some handshakes to fail.
* Fix possible miscomputation of the premaster secret with DHE-PSK key
exchange that caused some handshakes to fail with other implementations.
(Failure rate <= 1/255 with common DHM moduli.)
* Disable broken Sparc64 bn_mul assembly (found by Florian Obser).
* Fix base64_decode() to return and check length correctly (in case of
tight buffers)
* Fix mpi_write_string() to write "00" as hex output for empty MPI (found
by Hui Dong)

Karger)

ciphersuites, for full SSL frames of data.

ServerHello when no extensions are present (found by Matthew Page)

* On OpenBSD, use arc4random_buf() instead of rand() to prevent warnings
* mpi_fill_random() was creating numbers larger than requested on
big-endian platform when size was not an integer number of limbs
* Fix dependencies issues in X.509 test suite.
* Some parts of ssl_tls.c were compiled even when the module was disabled.

certificates (POLARSSL_X509_CHECK_KEY_USAGE)

This affects certificates in the user-supplied chain except the top
certificate. If the user-supplied chain contains only one certificates,
it is not affected (ie, its notAfter date is properly checked).
* Prevent potential NULL pointer dereference in ssl_read_record() (found by
TrustInSoft)
Bugfix

Shuo Chen).
* oid_get_numeric_string() used to truncate the output without returning an
error if the output buffer was just 1 byte too small.
* dhm_parse_dhm() (hence dhm_parse_dhmfile()) did not set dhm->len.
* Calling pk_debug() on an RSA-alt key would segfault.
* pk_get_size() and pk_get_len() were off by a factor 8 for RSA-alt keys.
* Potential buffer overwrite in pem_write_buffer() because of low length
indication (found by Thijs Alkemade)
* EC curves constants, which should be only in ROM since 1.3.3, were also
stored in RAM due to missing 'const's (found by Gergely Budai).

* mpi_init() and mpi_free() now only accept a single MPI
argument and do not accept variable argument lists anymore.
* The error codes have been remapped and combining error codes
is now done with a PLUS instead of an OR as error codes
used are negative.
* Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
net_recv() now returns 0 on EOF instead of
POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
after the handshake.

before parsing a key or keyfile!

platform (32-bit / 64-bit) (Fixes ticket #19, found by Mads
Kiilerich and Mihai Militaru)
