* 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 Hudson2012-04-261-86/+26
| | | | | | | | | | | | | 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

* securID error handling fixSam Hartman2010-10-191-24/+24
| | | | | | | | | | | In porting forward, I incorrectly used krb5_set_error_message instead of com_err. This commit reverts that change. ticket: 6806 target_version: 1.9 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24466 dc483132-0cff-0310-8789-dd5450dbe970
* securID code fixesSam Hartman2010-10-191-14/+6
| | | | | | | | | | | | | | | | | | | | | | Fixes to get securID preauth plugin working. A separate patch will address error handling and build issues. * Permit a preauth plugin to return KRB5KDC_ERR_PREAUTH_REQUIRED from the verify entry point. * If verify_securid2 fails, save the return value and return that rather than success after dealing with encoding the out_edata * Use the client key not the securid principal key for the sam checksum * indicate that securID is hardware authentication ticket: 6805 target_version: 1.9 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24465 dc483132-0cff-0310-8789-dd5450dbe970
