* Use k5_setmsgGreg Hudson2014-06-051-3/+3
| | | | | | Replace most calls to krb5_set_error_message with k5_setmsg for brevity. Leave alone plugin sources where we don't include k5-int.h (mostly PKINIT).
* Reduce boilerplate in makefilesGreg Hudson2013-05-161-14/+0
| | | | | | | | | Provide default values in pre.in for PROG_LIBPATH, PROG_RPATH, SHLIB_DIRS, SHLIB_RDIRS, and STOBJLISTS so that they don't have to be specified in the common case. Rename KRB5_RUN_ENV and KRB5_RUN_VARS to RUN_SETUP (already the most commonly used name) and RUN_VARS. Make sure to use DEFINES for local defines (not DEFS). Remove some other unnecessary makefile content.
* Avoid passing null pointers to memcpy/memcmpGreg Hudson2013-04-081-1/+2
| | | | | | | | | | | | | | | By a strict reading of the C standard, memcpy and memcmp have undefined behavior if their pointer arguments aren't valid object pointers, even if the length argument is 0. Compilers are becoming more aggressive about breaking code with undefined behavior, so we should try to avoid it when possible. In a krb5_data object, we frequently use NULL as the data value when the length is 0. Accordingly, we should avoid copying from or comparing the data field of a length-0 krb5_data object. Add checks to our wrapper functions (like data_eq and k5_memdup) and to code which works with possibly-empty krb5_data objects. In a few places, use wrapper functions to simplify the code rather than adding checks.
* Make it easier to test SAM-2 client codeGreg Hudson2012-04-266-120/+407
| | | | | | | | | | | | | Add a method to the securid_sam2 plugin, built with alternate compile-time flags, which supplies a plain-text challenge to the client to be used as the OTP value. This lets us manually exercise the SAM-2 client code and a little bit of the KDC code. securid_make_sam_challenge_2_and_cksum is moved into the method- independent code and renamed. get_securid_edata_2 has its sc2b parameter removed as it was not used by the caller. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25832 dc483132-0cff-0310-8789-dd5450dbe970
* Convert securid module edata methodGreg Hudson2012-01-071-4/+9
| | | | | | | | | | | | r25348 made modified the edata method of the kdcpreauth interface to be async-capable, but neglected to convert the securid_sam2 module's edata function. Do that now. ticket: 7060 target_version: 1.10 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25621 dc483132-0cff-0310-8789-dd5450dbe970
* Get rid of fake-installGreg Hudson2011-11-041-1/+1
| | | | | | | | | Instead, use $(BUILDTOP)/plugins as the plugin base for tests. For each real plugin module, create a link in the parent directory if we're doing a shared-library build--so built KDB modules can be found in plugins/kdb, preauth modules in plugins/preauth, etc.. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25436 dc483132-0cff-0310-8789-dd5450dbe970
* Use type-safe callbacks in preauth interfaceGreg Hudson2011-10-061-27/+6
| | | | | | | | | | | | | | | Replace the generic get_data functions in clpreauth and kdcpreauth with structures containing callback functions. Each structure has a minor version number to allow adding new callbacks. For simplicity, the new fast armor key callbacks return aliases, which is how we would supply the armor key as a function parameter. The new client keys callback is paired with a free_keys callback to reduce the amount of cleanup code needed in modules. ticket: 6971 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25315 dc483132-0cff-0310-8789-dd5450dbe970
* Use an opaque handle in the kdcpreauth callbackGreg Hudson2011-10-051-13/+23
| | | | | | | | | | | | | | Instead of passing a request and entry to the kdcpreauth get_data callback, pass an opaque handle. Remove DB entry and key data parameters from kdcpreauth methods (but keep the request, since that's transparent). The SecurID plugin links against libkdb5 and needs access to the client DB entry. Rather than continue to pass a DB entry to kdcpreauth methods, add a get_data callback to get the client DB entry for the few plugins which might need it. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25300 dc483132-0cff-0310-8789-dd5450dbe970

* Convert preauth_plugin.h to new plugin frameworkGreg Hudson2011-06-171-16/+26
| | | | | | | | | | | | | | | | | | | | | | | | The preauth plugin interface was introduced in 1.6 but was never made a public API. In preparation for making it public in 1.10, convert it to use the new plugin framework. This will require changes to any existing preauth plugins. A number of symbols were renamed for namespace cleanliness, and abstract types were introduced for module data and module per-request data for better type safety. On the consumer end (preauth2.c and kdc_preauth.c), this is a pretty rough conversion. Eventually we should create proper consumer APIs with module handles, and the flat lists of preauth types should hold pointers to module handles rather than copies of the vtables. The built-in preauth type handlers should then be converted to built-in module providers linked into the consumer code (as should encrypted challenge, since it has no external dependencies). None of this will impact the provider API for preauth plugins, so it can wait. ticket: 6921 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24970 dc483132-0cff-0310-8789-dd5450dbe970
