Use BUF_strlcat() instead of strcat().
Use BIO_snprintf() instead of sprintf().
In some cases, keep better track of buffer lengths.
This is part of a large change submitted by Markus Friedl <markus@openbsd.org>
exit() in whatever way works for the intended platform, and define
OPENSSL_EXIT() to have the old meaning (the name is of course because
it's only used in the openssl program)
CONF_modules_unload() now calls CONF_modules_finish()
automatically.
Default use of section openssl_conf moved to
CONF_modules_load()
Load config file in several openssl utilities.
Most utilities now load modules from the config file,
though in a few (such as version) this isn't done
because it couldn't be used for anything.
In the case of ca and req the config file used is
the same as the utility itself: that is the -config
command line option can be used to specify an
alternative file.
to go the monolith way (does anyone do that these days?).
NOTE: a few applications are missing in this commit. I've a few more
changes in them that I haven't tested yet.
ENGINE.
* Extra verbosity can be added with more "v"'s, eg. '-vvv' gives
information about input flags and descriptions for each control command
in each ENGINE. Check the output of "openssl engine -vvv" for example.
* '-pre <cmd>' and '-post <cmd>' can be used to invoke control commands on
the specified ENGINE (or on all of them if no engine id is specified,
although that usually gets pretty ugly). '-post' commands are only
attempted if '-t' is specified and the engine successfully initialises.
'-pre' commands are always attempted whether or not '-t' causes an
initialisation to be tried afterwards. Multiple '-pre' and/or '-post'
commands can be specified and they will be called in the order they
occur on the command line.
Parameterised commands (the normal case, there are currently no
unparameterised ones) are split into command and argument via a separating
colon. Eg. "openssl engine -pre SO_PATH:/lib/libdriver.so <id>" results in
the call;
ENGINE_ctrl_cmd_string(e, "SO_PATH", "/lib/libdriver.so", 0);
Application code should similarly allow arbitrary name-value string pairs
to be passed into ENGINEs in a manner matching that in apps/engine.c,
either using the same colon-separated format, or entered as two distinct
strings. Eg. as stored in a registry. The last parameter of
ENGINE_ctrl_cmd_string can be changed from 0 to 1 if the command should
only be attempted if it's supported by the specified ENGINE (eg. for
commands like "FORK_CHECK:1" that may or may not apply to the run-time
ENGINE).
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.
load the "external" built-in engines (those that require DSO). This
makes linking with libdl or other dso libraries non-mandatory.
Change 'openssl engine' accordingly.
Change the engine header files so some declarations (that differed at
that!) aren't duplicated, and make sure engine_int.h includes
engine.h. That way, there should be no way of missing the needed
info.
implementation is contained in the application, and the capability
string building part should really be part of the engine library.
This is therefore an experimental hack, and will be changed in the
near future.
