* Explain the ASN.1 restriction that requires extra logic for encoding.doug2015-06-132-4/+36
| | | | ok miod@ jsing@
* When initial capacity is 0, always use NULL buffer.doug2015-06-132-14/+16
| | | | | | | malloc(0) is implementation defined and there's no reason to introduce that ambiguity here. Added a few cosmetic changes in sizeof and free. ok miod@ jsing@
* Add comments about how the CBS constants are constructed.doug2015-06-132-24/+86
| | | | | | Also, introduce a few more #defines to make it obvious. ok miod@ jsing@
* Reject long-form tags in CBS_peek_asn1_tag.doug2015-06-132-2/+16
| | | | | | Currently, CBS only handles short-form tags. ok miod@ jsing@
* Fix bad indenting in LibreSSL.doug2015-06-1310-24/+24
| | | | | | | | | jsg@ noticed that some of the lines in libssl and libcrypto are not indented properly. At a quick glance, it looks like it has a different control flow than it really does. I checked the history in our tree and in OpenSSL to make sure these were simple mistakes. ok miod@ jsing@
* Remove unneeded sys/sysctl.h on linux.bcook2015-06-132-4/+2
| | | | This only provides the sysctl wrapper in glibc, which we do not use and is not available in other libc implementations for Linux. Thanks to ncopa from github.
* Avoid an infinite loop that can occur when verifying a message with anlibressl-v2.2.0jsing2015-06-112-4/+4
| | | | | | | | | | unknown hash function OID. Diff based on OpenSSL. Fixes CVE-2015-1792 (however, this code is not enabled/built in LibreSSL). ok doug@ miod@
* Avoid a potential out-of-bounds read in X509_cmp_time(), due to missingjsing2015-06-112-8/+54
| | | | | | | | | | length checks. Diff based on changes in OpenSSL. Fixes CVE-2015-1789. ok doug@
* Avoid an infinite loop that can be triggered by parsing an ASN.1jsing2015-06-112-6/+16
| | | | | | | | | | | ECParameters structure that has a specially malformed binary polynomial field. Issue reported by Joseph Barr-Pixton and fix based on OpenSSL. Fixes CVE-2015-1788. ok doug@ miod@

* Add OPENSSL_NO_EGD to opensslfeatures.h.bcook2015-05-262-0/+2
| | | | | | | Since RAND_egd has been removed from LibreSSL, simplify porting software that relies on it. See https://github.com/libressl-portable/openbsd/pull/34 from Bernard Spil, ok deraadt@

* Fix return paths with missing EVP_CIPHER_CTX_cleanup() calls.jsg2015-05-1510-30/+32
| | | | ok doug@
* rev 1.3 introduced a check to an if statement without adding braces.jsg2015-05-141-3/+1
| | | | | | | Claudio points out the size is checked by an earlier test so just remove it to restore the original handling of the partial octet case. Discussed with claudio and gilles.

* Rename cbb_buffer_add_u to cbb_add_u and remove redundant code.doug2015-04-292-30/+12
| | | | | | | All of cbb_buffer_add_u's callers first call CBB_flush and send cbb->base. cbb_add_u() now has that common code in one place. ok jsing@

* Add missing BN_CTX_end() calls.doug2015-04-298-36/+36
| | | | | | | | After calling BN_CTX_start(), there must be a BN_CTX_end() before returning. There were missing BN_CTX_end() calls in error paths. One diff chunk was simply removing redundant code related to this. ok deraadt@
* Not all Linux libc's include linux/sysctl.h in sys/sysctl.h.bcook2015-04-272-4/+6
| | | | Include it if we have the sysctl syscall.
* Support AIX versions without WPAR support.bcook2015-04-272-2/+10
| | | | From Michael Felt.
* Don't ignore the reference count in X509_STORE_free.doug2015-04-252-2/+10
| | | | | | | | | Based on this upstream commit: bff9ce4db38b297c72a6d84617d71ae2934450f7 which didn't make it into a release until 1.0.2. Thanks to william at 25thandclement dot com for reporting this! ok deraadt@ jsing@ beck@
* Check for invalid leading zeros in CBS_get_asn1_uint64.doug2015-04-253-8/+20
| | | | | | | | | | ASN.1 integers cannot have all zeros or all ones for the first 9 bits. This rule ensures the numbers are encoded with the smallest number of content octets (see ITU-T Rec X.690 section 8.3.2). Based on BoringSSL commit 5933723b7b592e9914f703d630b596e140c93e16 ok deraadt@ jsing@

* Only set the cipher list if one was specified and actually check the returnjsing2015-04-151-7/+12
| | | | | | | value from SSL_CTX_set_cipher_list(). Also remove pointless getenv() handling. ok bcook@ doug@
* Clean up the ssl_bytes_to_cipher_list() API - rather than having thejsing2015-04-156-42/+30
| | | | | | | | | | ability to pass or not pass a STACK_OF(SSL_CIPHER) *, which is then either zeroed or if NULL a new one is allocated, always allocate one and return it directly. Inspired by simliar changes in BoringSSL. ok beck@ doug@
* Now that tls_close() is more robust, consider a failure to be fatal.jsing2015-04-151-1/+1

* Treat SSL_ERROR_ZERO_RETURN as a success, rather than a failure. Alsojsing2015-04-151-5/+6
| | | | | | | ensure that outlen is set to zero so that tls_read() has read(2) like semantics for EOF. Spotted by doug@
* Make tls_close() more robust - do not rely on a close notify being receivedjsing2015-04-151-13/+17
| | | | | | | | | | | from the other side and only return TLS_READ_AGAIN/TLS_WRITE_AGAIN if we failed to send a close notify on a non-blocking socket. Otherwise be more forceful and always shutdown/close the socket regardless of other failures. Also do not consider ENOTCONN or ECONNRESET to be a shutdown failure, since there are various situations where this can occur. ok doug@ guenther@
* Another couple of commas in the wrong place, ok jmcnicm2015-04-141-3/+3
