The plugin interfaces were originally implemented for use on
Unix where KRB5_CALLCONV, HEIM_CALLCONV and similar are defined
as nothing. However, on 32-bit Windows the calling convention
matters and executing a __stdcall function through a __cdecl
function pointer will result in failures.
This change updates the krb5plugin_windc, krb5plugin_service_locate,
krb5plugin_send_to_kdc plugins to specify the KRB5_CALLCONV for
functions. This brings the plugins into compliance with the
heim_plugin_common interface requirement that init() and fini()
use the platform specified HEIM_CALLCONV.
The krb5-plugin(7) man page is updated and the lib/krb5/test_plugin
test is also fixed.
With this change all tests pass on 32-bit Windows.
Change-Id: Ic9d2e1285c9c179e3898dc9d071ed092bcddc406
Refactor plugin framework to use a single list of loaded plugins; add a new
plugin API where DSOs export a load function that can declare dependencies and
export multiple plugins; refactor kadm5 hook API to use krb5 plugin framework.
More information in krb5-plugin(7).
The resolver plugin doesn't have a way to say "and stop here", so the
lookup done in lib/krb5/test_plugin.c can produce more results than used
to be expected, and indeed nowadays it does. The fix is to ensure that
we have the desired results and ignore the others.
