| | | | | | | | using the name of relayd relay or smtpd pki, use a 32 byte arc4random buffer that should be unique for the context. This fixes an issue in OpenSMTPD when a long pki name could break the configuration. OK gilles@ benno@

| | | | | | | | since yesterday, "mandoc -Tlint -Wfatal" can no longer fail. Instead, as suggested by deraadt@, provide a manlint target that is *not* run during make build, but can be run whenever you want to check syntax of manuals. "nice stuff" deraadt@

* For non-blocking sockets tls_connect_fds() could fail with EAGAIN.bluhm2015-01-132-7/+22
| | | | | | | | Use the same logic from the read, write, accept functions to inform the caller wether a readable or writable socket is needed. After that event, the connect function must be called again. All the checks before connecting are done only once. OK tedu@

| | | | | | | | Free data->saved_message.data. Based on OpenSSL commit: 41cd41c4416f545a18ead37e09e437c75fa07c95 except this version sets a->ptr to NULL to avoid accidental reuse and handles malloc failing. ok beck@, input + ok miod@

* set errno = EINVAL for invalid salts and hashes in most functions.tedu2015-01-071-12/+20
| | | | | | | remember to set EACCES in bcrypt_checkpass for hash differences. the higher level crypt_checkpass function will reset errno to EACCES in all cases, which is probably the right behavior, but this change gives code working with the lower level functions the correct errno if they care.

| | | | | guenther suggested using thread time, which actually may improve accuracy if somebody puts this in a threaded program.
* Fix incorrect OPENSSL_assert() usage.doug2015-01-032-48/+106
| | | | | | | | Instead of asserting, return an error code for I/O errors. This is based on OpenSSL commit 2521fcd8527008ceb3e4748f95b0ed4e2d70cfef. Added checks for two calloc()s while I'm here. ok miod@

| | | | | | | afterwards. openssl has a more complicated fix, but it's less intrusive for now to simply hoist the expensive part (fake key generation) up without sweating a branch or two. ok bcook jsing

| | | | | | | | | use global data. The simplest fix is to only check blowfish passwords, and implicitly lock out DES passwords. crypt_checkpass is currently only used in one place, passwd, to verify the local user's password, so this is probably acceptable. Gives people a little more time to migrate away from DES before introduing checkpass into more places.
* Add size_t to int checks for SSL functions.doug2014-12-173-8/+39
| | | | | | | | | | libtls accepts size_t for lengths but libssl accepts int. This verifies that the input does not exceed INT_MAX. It also avoids truncating size_t when comparing with int and adds printf-style attributes for tls_set_error(). with input from deraadt@ and tedu@ ok tedu@

| | | | the Camellia ciphersuites for TLS 1.2 introduced in RFC 5932. From OpenSSL HEAD.
* Add error handling for EVP_DigestInit_ex().doug2014-12-1515-56/+98
| | | | | | | | | | | | | A few EVP_DigestInit_ex() calls were left alone since reporting an error would change the public API. Changed internal ssl3_cbc_digest_record() to return a value due to the above change. It will also now set md_out_size=0 on failure. This is based on part of BoringSSL's commit to fix malloc crashes: https://boringssl.googlesource.com/boringssl/+/69a01608f33ab6fe2c3485d94aef1fe9eacf5364 ok miod@
* unconditionally align SSL payloadsbcook2014-12-146-78/+36
| | | | | | | | Remove support for conditional payload alignment, since we would never want to turn it off. Also, consistently use size_t for calculating the alignment. ok miod@

* Provide functions for starting, finishing and writing SSL handshakejsing2014-12-146-8/+120
| | | | | | | | | | | | | | | messages. This will allow for removal of repeated/duplicated code. Additionally, DTLS was written by wholesale copying of the SSL/TLS code, with some DTLS specifics being added to the duplicated code. Since these SSL handshake message functions know how to handle both SSL/TLS and DTLS, upon conversion the duplicate versions will become identical (or close to), at which point the DTLS versions can be removed and the SSL/TLS versions used for both protocols. Partially based on similar changes in OpenSSL. ok miod@
