* Fix krb5_cc_set_configGreg Hudson2011-10-201-8/+6
| | | | | | | | | | | | | | | krb5_cc_set_config has been non-functional since r24753 on cache types which don't support removal of credential entries. Fix it by only calling krb5_cc_remove_cred if data is NULL, since krb5_cc_store_cred will do it anyway in the positive case. Also fix an old memory leak in an uncommon error case. ticket: 6987 target_version: 1.10 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25384 dc483132-0cff-0310-8789-dd5450dbe970

* Ensure termination in Windows vsnprintf wrapperGreg Hudson2011-10-181-1/+3
| | | | | | | | | | | | | | | The Windows _vsnprintf does not terminate its output buffer in the overflow case. Make sure we do that in the wrapper. Reported by Chris Hecker.

* RFC 4120 says that we should not canonicalize using DNS. We cannot getSam Hartman2011-10-171-4/+3
| | | | | | | | | | | | | | that far today, but there's no reason we should fail to use a perfectly good principal name just because DNS is failing. For some services there isn't even a requirement they be in DNS. With AI_ADDRCONFIG there's no reason that Kerberos canonicalization should fail simply because a v6 address is not present, for example. So, if getaddrinfo fails in krb5_sname_to_principal simply use the input hostname uncanonicalized. sn2princ: On getaddrinfo failure use the input git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25357 dc483132-0cff-0310-8789-dd5450dbe970
* Allow password changes over NATsGreg Hudson2011-10-151-23/+8
| | | | | | | | | | | | In the kpasswd server code, don't set a remote address in the auth context before calling krb5_rd_priv, since the kpasswd protocol is well-protected against reflection attacks. This allows password changes to work in cases where a NAT has changed the client IP address as it is seen by the server. ticket: 6979 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25356 dc483132-0cff-0310-8789-dd5450dbe970
* Allow rd_priv/rd_safe without remote addressGreg Hudson2011-10-153-12/+18
| | | | | | | | | | | | | | Allow krb5_rd_priv and krb5_rd_safe to work when there is no remote address set in the auth context, unless the KRB5_AUTH_CONTEXT_DO_TIMES flag is set (in which case we need the remote address for the replay cache name). Note that failing to set the remote address can create a vulnerability to reflection attacks in some protocols, although it is fairly easy to defend against--either use sequence numbers, or make sure that requests don't look like replies, or both. ticket: 6978 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25355 dc483132-0cff-0310-8789-dd5450dbe970

* Rename PAC type constants to avoid conflictsGreg Hudson2011-10-153-36/+53
| | | | | | | | Since the PAC type constants are now exposed in krb5.h, give them a KRB5_ prefix so they don't conflict with similar PAC type constants in other packages, like Samba. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25352 dc483132-0cff-0310-8789-dd5450dbe970
* Hide gak_fct interface and arguments in clpreauthGreg Hudson2011-10-159-187/+127
| | | | | | | | | | | | | | | | | | | | | | Remove the gak_fct, gak_data, salt, s2kparams, and as_key arguments of krb5_clpreauth_process_fn and krb5_clpreauth_tryagain_fn. To replace them, add two callbacks: one which gets the AS key using the previously selected etype-info2 information, and a second which lets the module replace the AS key with one it has computed. This changes limits module flexibility in a few ways. Modules cannot check whether the AS key was already obtained before asking for it, and they cannot use the etype-info2 salt and s2kparams for purposes other than getting the password-based AS key. It is believed that of existing preauth mechanisms, only SAM-2 preauth needs more flexibility than the new interfaces provide, and as an internal legacy mechanism it can cheat. Future mechanisms should be okay since the current IETF philosophy is that etype-info2 information should not be used for other purposes. ticket: 6976 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25351 dc483132-0cff-0310-8789-dd5450dbe970

* Add new header gssapi_alloc.hSam Hartman2011-10-147-4/+74
| | | | | | | | | | | | | | | Contains allocator methods for use with mechanisms and mechglues for allocations that must be made in one module but freed in another. On windows, an allocation made in one module cannot safely be freed in another using the usual c runtime malloc/free; runtime dll mismatch will cause heap corruption in that case. But it is safe to instead directly use HeapAlloc()/HeapFree() specifying the default process heap. For now, this header is not public. If it becomes public strncpy will need to be used instead of strlcpy.
