2015-06-02Standardize handling of #ifdef'd options.Rich Salz
Here are the "rules" for handling flags that depend on #ifdef: - Do not ifdef the enum. Only ifdef the OPTIONS table. All ifdef'd entries appear at the end; by convention "engine" is last. This ensures that at run-time, the flag will never be recognized/allowed. The next two bullets entries are for silencing compiler warnings: - In the while/switch parsing statement, use #ifdef for the body to disable it; leave the "case OPT_xxx:" and "break" statements outside the ifdef/ifndef. See ciphers.c for example. - If there are multiple options controlled by a single guard, OPT_FOO, OPT_BAR, etc., put a an #ifdef around the set, and then do "#else" and a series of case labels and a break. See OPENSSL_NO_AES in cms.c for example. Reviewed-by: Matt Caswell <matt@openssl.org>

2015-05-16Server side version negotiation rewriteMatt Caswell
This commit changes the way that we do server side protocol version negotiation. Previously we had a whole set of code that had an "up front" state machine dedicated to the negotiating the protocol version. This adds significant complexity to the state machine. Historically the justification for doing this was the support of SSLv2 which works quite differently to SSLv3+. However, we have now removed support for SSLv2 so there is little reason to maintain this complexity. The one slight difficulty is that, although we no longer support SSLv2, we do still support an SSLv3+ ClientHello in an SSLv2 backward compatible ClientHello format. This is generally only used by legacy clients. This commit adds support within the SSLv3 code for these legacy format ClientHellos. Server side version negotiation now works in much the same was as DTLS, i.e. we introduce the concept of TLS_ANY_VERSION. If s->version is set to that then when a ClientHello is received it will work out the most appropriate version to respond with. Also, SSLv23_method and SSLv23_server_method have been replaced with TLS_method and TLS_server_method respectively. The old SSLv23* names still exist as macros pointing at the new name, although they are deprecated. Subsequent commits will look at client side version negotiation, as well of removal of the old s23* code. Reviewed-by: Kurt Roeckx <kurt@openssl.org>

After the finale, the "real" final part. :) Do a recursive grep with "-B1 -w [a-zA-Z0-9_]*_free" to see if any of the preceeding lines are an "if NULL" check that can be removed. Reviewed-by: Tim Hudson <tjh@openssl.org>
2015-04-24Big apps cleanup (option-parsing, etc)Rich Salz
This is merges the old "rsalz-monolith" branch over to master. The biggest change is that option parsing switch from cascasding 'else if strcmp("-foo")' to a utility routine and somethin akin to getopt. Also, an error in the command line no longer prints the full summary; use -help (or --help :) for that. There have been many other changes and code-cleanup, see bullet list below.

OPENSSL_NO_SSL_INTERN all ssl related structures are opaque and internals cannot be directly accessed. Many applications will need some modification to support this and most likely some additional functions added to OpenSSL. The advantage of this option is that any application supporting it will still be binary compatible if SSL structures change.

sure they are available in opensslconf.h, by giving them names starting with "OPENSSL_" to avoid conflicts with other packages and by making sure e_os2.h will cover all platform-specific cases together with opensslconf.h. I've checked fairly well that nothing breaks with this (apart from external software that will adapt if they have used something like NO_KRB5), but I can't guarantee it completely, so a review of this change would be a good thing.
2001-02-06format stringsUlf Möller
2000-09-20On VMS, stdout may very well lead to a file that is written to in aRichard Levitte
record-oriented fashion. That means that every write() will write a separate record, which will be read separately by the programs trying to read from it. This can be very confusing. The solution is to put a BIO filter in the way that will buffer text until a linefeed is reached, and then write everything a line at a time, so every record written will be an actual line, not chunks of lines and not (usually doesn't happen, but I've seen it once) several lines in one record. Voila, BIO_f_linebuffer() is born. Since we're so close to release time, I'm making this VMS-only for now, just to make sure no code is needlessly broken by this. After the release, this BIO method will be enabled on all other platforms as well.
