2020-06-24Document eight additional pre-OpenSSL-1.1 accessor functions that areIngo Schwarze
still widely used according to code searches on the web, so people reading existing code will occasionally want to look them up. While here, correct the return type of X509_CRL_get0_lastUpdate(3) and X509_CRL_get0_nextUpdate(3), which return const pointers. Also, add some precision regarding RETURN VALUES.
2020-06-24Enforce restrictions for ClientHello extensionsTheo Buehler
RFC 8446 section 9.2 imposes some requirements on the extensions sent in the ClientHello: key_share and supported_groups must either both be present or both be absent. If no pre_shared_key was sent, the CH must contain both signature_algorithms and supported_groups. If either of these conditions is violated, servers must abort the handshake with a missing_extensions alert. Add a function that enforces this. If we are going to enforce that clients send an SNI, we can also do this in this function. Fixes failing test case in tlsfuzzer's test-tls13-keyshare-omitted.py ok beck inoguchi jsing

2020-06-22Extend kqueue interface with EVFILT_EXCEPT filter.Martin Pieuchot
This filter, already implemented in macOS and Dragonfly BSD, returns exceptional conditions like the reception of out-of-band data. The functionnality is similar to poll(2)'s POLLPRI & POLLRDBAND and it can be used by the kqfilter-based poll & select implementation. ok millert@ on a previous version, ok visa@

2020-06-19We inherited the constant time CBC padding removal from BoringSSL, butTheo Buehler
missed a subsequent fix for an off-by-one in that code. If the first byte of a CBC padding of length 255 is mangled, we don't detect that. Adam Langley's BoringSSL commit 80842bdb44855dd7f1dde64a3fa9f4e782310fc7 Fixes the failing tlsfuzzer lucky 13 test case. ok beck inoguchi

and some other wording improvements with respect to types; OK ratchov@
2020-06-18Many of these functions have several arguments, and some argumentsIngo Schwarze
are very long (function pointers), such that a number of input lines in the SYNOPSIS do not fit into 80 columns. Consequently, consistently use .Fo/.Fa/.Fc rather than .Fn for better readability of the source code. Mechanical diff, no output change.

2020-06-09The check_includes step is incorrect dependency management model forTheo de Raadt
how our tree gets built. If this was done in all the libraries (imagine sys/dev), it would disrupt the development process hugely. So it should not be done here either. use 'make includes' by hand instead.

2020-06-05Add a custom copy handler for AES key wrapTheo Buehler
This is necessary because ctx->cipher_data is an EVP_AES_WRAP_CTX containing a pointer to ctx->iv. EVP_CIPHER_CTX_copy() uses memcpy to copy cipher_data to the target struct. The result is that the copy contains a pointer to the wrong struct, which then leads to a use-after-free. The custom copy handler fixes things up to avoid that.

GOST cipher suites requires that CertVerify signatures be generated in a special way (see ssl3_send_client_kex_gost(), ssl3_get_cert_verify()). However, the GOST_SIG_FORMAT_RS_LE flag was not passed in case of TLS 1.2 connections (because they use different code path). Set this flag on GOST PKEYs.

2020-06-04When X509_ATTRIBUTE_create() receives an invalid NID (e.g., -1), returnIngo Schwarze
failure rather than silently constructing a broken X509_ATTRIBUTE object that might cause NULL pointer accesses later on. This matters because X509_ATTRIBUTE_create() is used by documented API functions like PKCS7_add_attribute(3) and the NID comes straight from the user. This fixes a bug found while working on documentation. OK tb@ and "thanks" bluhm@
