two functions that did expansion on in parameters (BN_mul() and
BN_sqr()). The problem was solved by making bn_dup_expand() which is
a mix of bn_expand2() and BN_dup().
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.
automatically, however some code was still referring to the original
pointer rather than the internal one (and thus to NULL instead of the
created pointer).
translate library names by only adding ".so" to them without
prepending them with "lib". Add the flag DSO_FLAG_NAME_TRANSLATION_EXT_ONLY
for that purpose.
appropriate filename translation on the host system. Apart from this point,
users should also note that there's a slight change in the API functions
too. The DSO now contains its own to-be-converted filename
("dso->filename"), and at the time the DSO loads the "dso->loaded_filename"
value is set to the translated form. As such, this also provides an impicit
way of determining if the DSO is currently loaded or not. Except, perhaps,
VMS .... :-)
The various DSO_METHODs have been updated for this mechanism except VMS
which is deliberately broken for now, Richard is going to look at how to
fit it in (the source comments in there explain "the issue").
Basically, the new callback scheme allows the filename conversion to
(a) be turned off altogether through the use of the
DSO_FLAG_NO_NAME_TRANSLATION flag,
(b) be handled in the default way using the default DSO_METHOD's converter
(c) overriden per-DSO by setting the override callback
(d) a mix of (b) and (c) - eg. implement an override callback that;
(i) checks if we're win32 "if(strstr(dso->meth->name, "win32"))..."
and if so, convert "blah" into "blah32.dll" (the default is
otherwise to make it "blah.dll").
(ii) default to the normal behaviour - eg. we're not on win32, so
finish with (return dso->meth->dso_name_converter(dso,NULL)).
(e) be retried a number of times by writing a new DSO_METHOD where the
"dso_load()" handler will call the converter repeatedly. Then the
custom converter could use state information in the DSO to suggest
different conversions or paths each time it is invoked.
NCONF_get_number_e() is defined (_e for "error checking") and is
promoted strongly. The old NCONF_get_number is kept around for
binary backward compatibility.
