2019-03-31Clean up and simplify the client verify code:Joel Sing
- Be consistent with _len naming. - Use size_t where possible/appropriate. - Group the CBB code. - Use EVP_MAX_MD_SIZE consistently, instead of "magic" values. - Switch GOST to EVP_DigestSign*, making it similar to sigalgs. ok tb@ a while back.

2019-03-29Copy categories outside "mask" from "oldloc" to the new locale object.Ingo Schwarze
While POSIX appears to allow the old behaviour of ignoring "oldloc", Ted and Karl convinced me that is a bug in the spec and the Austin group almost certainly intended to require the new behaviour. Anyway, compatibility strongly suggests the new behaviour because most (or maybe even all?) other systems do not ignore "oldloc", and some software appears to depend on the copying from "oldloc" to the new locale. Issue analyzed and reported by Karl Williamson <public at khwilliamson dot com> with support from the Perl 5 community. This final diff is similar to two earlier diffs from Ted, but handles invalid input in a mode robust way. OK tedu@.

2019-03-26adjtime(2): set EINVAL if delta overflows 64 bits of microseconds.cheloha
No other (known) BSD-derived adjtime(2) implementation checks for overflow when converting delta into its final denomination of fractional seconds. This is peculiar, as the call originates in 4.3BSD. However, glibc, uclibc, and (to an extent) musl /do/ check the input and set EINVAL if it exceeds a certain bound, so we'll just use the errno that they use to be consistent with extant practice. Prompted by the comment kettenis@ left when we switched to storing the adjustment in an int64_t like ~5 years ago (kern_time.c,v 1.87). Positive feedback from deraadt@, manpage bits ok jmc@, no code complaints from otto@ or tedu@.

2019-03-25Strip out all of the pkey to sigalg and sigalg to pkey linkages.Joel Sing
These are no longer used now that we defer signature algorithm selection. ok beck@

2019-03-25Defer sigalgs selection until the certificate is known.Joel Sing
Previously the signature algorithm was selected when the TLS extension was parsed (or the client received a certificate request), however the actual certificate to be used is not known at this stage. This leads to various problems, including the selection of a signature algorithm that cannot be used with the certificate key size (as found by jeremy@ via ruby regress). Instead, store the signature algorithms list and only select a signature algorithm when we're ready to do signature generation. Joint work with beck@.
2019-03-25Rework ssl_ctx_use_certificate_chain_bio() to use the CERT_PKEY chain.Joel Sing
This means that any additional CA certificates end up on the per certificate chain, rather than the single/shared extra_certs. Also simplify this code and in particular, avoid setting the return value to indicate success until we've actually succeeded. ok beck@ tb@
2019-03-25Remove ssl_get_server_send_cert() which is now unused.Joel Sing
ok beck@ tb@
2019-03-25Rework ssl3_output_cert_chain() to take a CERT_PKEY and consider chains.Joel Sing
We will now include the certificates in the chain in the certificate list, or use the existing extra_certs if present. Failing that we fall back to the automatic chain building if not disabled. This also simplifies the code significantly. ok beck@ tb@
2019-03-25Add a chain member to CERT_PKEY and provide functions for manipulating it.Joel Sing
Note that this is not the full chain, as the leaf certificate currently remains in the x509 member of CERT_PKEY. Unfortunately we've got to contend with the fact that some OpenSSL *_chain_* APIs exclude the leaf certificate while others include it... ok beck@ tb@
2019-03-24BUGS goes last;Jason McIntyre
2019-03-24Document the fact that readlink(2) can bypass restrictions as neededBob Beck
by realpath(3). This will go away post 6.5. ok deraadt@
2019-03-24In the incredibly unbelievable circumstance where _rs_init() fails toTheo de Raadt
allocate pages, don't call abort() because of corefile data leakage concerns, but simply _exit(). The reasoning is _rs_init() will only fail if someone finds a way to apply specific pressure against this failure point, for the purpose of leaking information into a core which they can read. We don't need a corefile in this instance to debug that. So take this "lever" away from whoever in the future wants to do that.
2019-03-24If ssl_cipher_apply_rule() is given a specific cipher suite, match on it.Joel Sing
Otherwise matching a specific cipher is performed by matching against its characteristics, which can result in multiple rather than a single match. Found by bluhm@'s regress tests. ok bluhm@ tb@

2019-03-21Split EVP_rc4(3) out of EVP_EncryptInit(3) to reduce clutter.Ingo Schwarze
The algorithm is insecure and yet its description would spread over three paragraphs in the cipher list, including remarkable advice like using a 40 bit key length.
