EVP: If a key can't be exported to provider, fallback to legacy

Currently, the operations that do try to export a legacy key to
providers will fail if the export failed.  It makes more sense to
simply use the legacy method instead, as a fallback for things not
being implemented (yet) in a provider.

4 years agonmake: fix install_html_docs target
Dr. Matthias St. Pierre [Sat, 28 Dec 2019 22:03:29 +0000 (23:03 +0100)]
nmake: fix install_html_docs target

The nmake rule contains actually two errors:

1. The $< target[1] does not work for regular rules and is
expanded to an empty string after issuing the warning

    NMAKE : warning U4006: special macro undefined : '$<"'

Solution: replace $< by $?

2. The substitution regex is not quoted correctly, which leads
to the following error message by cmd.exe:

    'href' is not recognized as an internal or external command,
    operable program or batch file.

Solution: Quoting arguments for cmd.exe is really a nightmare,
but with the help of the excellent description [2] I was able to
properly quote the regex. Things were complicated by the fact that
a lot of levels of unquoting needed to be considered:

 * perl (windows-makefile.tmpl -> makefile)
 * make (reading the makefile)
 * cmd.exe (executed by make)
 * perl (scanning command line using CommandLineToArgvW())

The fix works, but the regex has become unmaintainable. It would actually
be better to wrap the entire command (including the regex) into a little
perl script which can be called by make directly.

4 years agoModify the add_seeds_stringlist() macro to fix a preprocessor error
Dr. Matthias St. Pierre [Mon, 6 Jan 2020 01:38:14 +0000 (02:38 +0100)]
Modify the add_seeds_stringlist() macro to fix a preprocessor error

When OpenSSL is configured using `--with-rand-seed=devrandom`, the preprocessor
reports the following error

    crypto/info.c:104:66: error:
            macro "add_seeds_stringlist" passed 3 arguments, but takes just 2
            add_seeds_stringlist("random-device", { DEVRANDOM, NULL });

The reason why the preprocessor complains about three arguments being passed
is that according to [1], balanced braces in macro arguments don't prevent the
comma from acting as an argument separator:

    3.3 Macro Arguments
    ...
    Parentheses within each argument must balance;
    a comma within such parentheses does not end the argument.
    However, there is no requirement for square brackets or braces to balance,
    and they do not prevent a comma from separating arguments.

Also introduced an iteration pointer `p`, because `dev` is not an lvalue:

    crypto/info.c:78:41: error:
            lvalue required as increment operand
            for (; *dev != NULL; dev++) {
