* BN_CTX_get() can fail - consistently check its return value.jsing2015-02-0928-273/+358
| | | | | | | | | | | | | | | There are currently cases where the return from each call is checked, the return from only the last call is checked and cases where it is not checked at all (including code in bn, ec and engine). Checking the last return value is valid as once the function fails it will continue to return NULL. However, in order to be consistent check each call with the same idiom. This makes it easy to verify. Note there are still a handful of cases that do not follow the idiom - these will be handled separately. ok beck@ doug@

| | | | | | | | OpenBSD does not have SCTP support and it sees little use in the wild. OPENSSL_NO_SCTP is already specified via opensslfeatures.h, hence this is a code removal only and symbols should remain unchanged. ok beck@ miod@ tedu@

* Return NULL when there are no shared ciphers.doug2015-02-092-8/+12
| | | | | | | | | | | | | | | | | OpenSSL added this change to avoid an out-of-bounds write since they're accessing p[-1]. We initialize buf and use strrchr() so we aren't subject to the same OOB write. However, we should return NULL rather than an empty string when there are no shared ciphers. Also, KNF a particularly bad section above here that miod noticed. Based on OpenSSL commits: 4ee356686f72ff849f6f3d58562224ace732b1a6 308505b838e4e3ce8485bb30f5b26e2766dc7f8b ok miod@

* Remove unused GOST test that prevents clang from building libcrypto.doug2015-02-091-55/+1
| | | | | | | | | | clang warns that it is unused and we have -Werror enabled. This test isn't hooked up to anything yet. We can add it back with a future GOST update. clang 3.5 can now build libssl and libcrypto as long as you use CFLAGS=-Wno-pointer-sign. "seems reasonable" bcook@, miod@

* Don't support very old versions of Netscape (is there any other kind?).doug2015-02-071-6/+5
| | | | | | | | | | | | | | Apparently "very old" Netscape versions illegally included empty content and a detached signature. OpenSSL removed the #if 0 that protected these users and added a new button OPENSSL_DONT_SUPPORT_OLD_NETSCAPE. It appears to be off by default to keep the hopes and dreams of very old Netscape users alive. We decided to be rebels and disable support. If you installed your browser from floppy disks, it's time to upgrade! Based on OpenSSL commit: 02a938c953b3e1ced71d9a832de1618f907eb96d ok tedu@, miod@, jsing@

| | | | | | | | | | | | | | | | | | | | | | | | | There are a few instances where #if 1 is removed but the code remains. Based on the following OpenSSL commits. Some of the commits weren't strictly deletions so they are going to be split up into separate commits. 6f91b017bbb7140f816721141ac156d1b828a6b3 3d47c1d331fdc7574d2275cda1a630ccdb624b08 dfb56425b68314b2b57e17c82c1df42e7a015132 c8fa2356a00cbaada8963f739e5570298311a060 f16a64d11f55c01f56baa62ebf1dec7f8fe718cb 9ccc00ef6ea65567622e40c49aca43f2c6d79cdb 02a938c953b3e1ced71d9a832de1618f907eb96d 75d0ebef2aef7a2c77b27575b8da898e22f3ccd5 d6fbb194095312f4722c81c9362dbd0de66cb656 6f1a93ad111c7dfe36a09a976c4c009079b19ea1 1a5adcfb5edfe23908b350f8757df405b0f5f71f 8de24b792743d11e1d5a0dcd336a49368750c577 a2b18e657ea1a932d125154f4e13ab2258796d90 8e964419603d2478dfb391c66e7ccb2dcc9776b4 32dfde107636ac9bc62a5b3233fe2a54dbc27008 input + ok jsing@, miod@, tedu@

| | | | | | | | | | | CBB_init_fixed() should not call free because it can lead to use after free or double free bugs. The caller should be responsible for creating and destroying the buffer.

* Provide a SSL_CIPHER_get_by_value() function that allows a cipher to bejsing2015-02-078-8/+66
| | | | | | | | | | | | | | retrieved via its cipher suite value. A corresponding SSL_CIPHER_by_value() function returns the cipher suite value for a given SSL_CIPHER. These functions should mean that software does not need to resort to put_cipher_by_char()/get_cipher_by_char() in order to locate a cipher. Begrudgingly also provide a SSL_CIPHER_get_by_id() function that locates a cipher via the internal cipher identifier. Unfortunately these have already been leaked outside the library via SSL_CIPHER_by_id() and the various SSL3_CK_* and TLS1_CK_* defines in the ssl3.h/tls1.h headers. ok beck@ miod@

| | | | | | | | | | CBS_get_asn1() and CBS_get_any_asn1_element() only support the single byte ASN.1 identifier octets (aka short form tags). Tag number 31 is the start of the multi-byte long form per X.690 section 8.1.2.4. From BoringSSL commit 2683af70e73f116e14db2bca6290fa4a010a2ee4 ok miod@
* KNF bytestring files.doug2015-02-068-1816/+2192
| | | | | | | | I checked that this doesn't change anything. Compiled with clang using -Wno-pointer-sign -g0 to reduce the differences. Only difference in the asm is due to assert(0) line number changes in bs_cbs.c and bs_cbb.c. miod is ok with the general process.

| | | | | | | | | | | | | | This is imported with as few changes as possible for the initial commit. I removed OPENSSL_EXPORT, replaced OPENSSL_malloc() etc with malloc() and changed a few header includes. BoringSSL has this as part of their public API. We're leaving it internal to libssl for now.
