* Get rid of KRB5_KDB_SRV_TYPE_PASSWDGreg Hudson2012-12-203-6/+1
| | | | | | Nothing was using KRB5_KDB_SRV_TYPE_PASSWD, so get rid of it. (kpasswdd is part of kadmind and interacts with the KDB using KRB5_KDB_SRV_TYPE_ADMIN.)
* Generate dependencies for kdb5_ldap_utilGreg Hudson2012-12-202-1/+105

* Remove LDAP realm krbTicketPolicyReference codeGreg Hudson2012-12-202-51/+1
| | | | | | ldap_realm.c had some code intended to handle a krbTicketPolicyReference from a krbRealmContainer object, but there wasn't enough of it to ever do anything. Remove it.
* Simplify LDAP KDB module container DN handlingGreg Hudson2012-12-2011-290/+87
| | | | | | | | | | | | | | | | | Outside of krb5_ldap_read_krbcontainer_params and krb5_ldap_create_krbcontainer, no fields of krb5_ldap_krbcontainer_params were used except for the DN. There was code to create a krbTicketPolicyReference attribute (which would fail because the schema doesn't allow that attribute, and was never exercised because kdb5_ldap_util would never set the parameter) and to read fields like max ticket life from the referenced ticket policy, but those fields were never used. Eliminate the structure and just store the container DN in krb5_ldap_context. Continue creating the container object when creating a realm (by calling krb5_ldap_create_krbcontainer unconditionally; it now exits successfully if the container already exists), but don't ever read it.
* Remove unneeded code in krb5_ldap_put_principalGreg Hudson2012-12-201-17/+7
| | | | | | krb5_ldap_put_principal contained some conditionals for the case where entry->princ is NULL, but only after entry->princ was dereferenced unconditionally. It's not necessary to handle this case, so don't.
* Remove unused functions in the LDAP KDB moduleGreg Hudson2012-12-205-342/+0

* Don't output trailing whitespace in depfix.plGreg Hudson2012-12-201-1/+1
| | | | | | | | All of our deps files have a trailing space in the first line, originating from depfix.pl. This space triggers the whitespace checker when generating a new deps file. Get rid of the trailing whitespace in the script; the change will be reflected in the deps files the next time they are regenerated.
* Pass through module errors when preauthenticatingGreg Hudson2012-12-203-18/+26
| | | | | | | | | | | | If we are responding to a KDC_ERR_PREAUTH_REQUIRED and cannot preauthenticate, report the error from the first real preauth type we tried. k5_preauth() now accepts a boolean input indicating that it must succeed on a real preauth type, instead of returning a boolean saying whether or not it did. ticket: 7517 (new)
* Rename internal preauth functionsGreg Hudson2012-12-196-130/+120
| | | | | | | | | | | | The preauth functions are internal to libkrb5, so use the k5_ prefix, don't use KRB5_CALLCONV, and prototype them in int-proto.h. Also remove krb5_do_preauth from the Unix libkrb5 export list. Reorder the k5_preauth() and k5_preauth_tryagain() arguments for more consistency with the clpreauth interface, and put the output padata arguments at the end. Rename any remaining uses of "kcontext" to "context" in preauth2.c.
* Make clpreauth flags function optionalGreg Hudson2012-12-196-31/+7
| | | | | | | | With one exception (KRB5_PADATA_PKINIT_KX), every padata type processed by a clpreauth module is now a real preauthentication type. Reduce the amount of boilerplate required for a clpreauth module by making the flags method optional if all of the preauth types advertised by the module are real.
* Use a proper consumer interface for clpreauthGreg Hudson2012-12-192-422/+365
| | | | | | | | In preauth2.c, use wrapper functions for calls to clpreauth functions. Get rid of the expanded-out module table, instead using a helper function to find the handle for a preauth type. Replace use counts with a list of previously processed pa types. Check for pa type conflicts when loading clpreauth modules.
* Separate clpreauth and kdcpreauth interfacesGreg Hudson2012-12-1969-2060/+2047
| | | | | | | Since there is no overlap between the clpreauth and kdcpreauth interface declarations, there's no particular reason to combine them into one header. For backward compatibility and convenience, leave behind a preauth_plugin.h which includes both.
* Save extended messages across fallback to masterGreg Hudson2012-12-192-33/+28
| | | | | | In krb5_get_init_creds_password and krb5_get_init_creds_keytab, save the extended error before retrying against the master KDC, and restore that state if returning the error from the original request.
* Add functions to save and restore error stateGreg Hudson2012-12-193-0/+38
|
* Simplify error message retrievalGreg Hudson2012-12-192-86/+37
| | | | | | Eliminate the scratch_buf field of struct error_info and just return a non-localized constant error message if we can't allocate a copy of the real one. Also rely on a conformant strerror().
* Style cleanup for internal error handlingGreg Hudson2012-12-1910-145/+147
| | | | | | | Fix style issues in kerrs.c and errors.c. Rename error handling functions to use shorter k5_ prefix. Eliminate an inoperable krb5int_set_error() call in gic_opte_alloc and convert the other call to use krb5_set_error_message().
* Regenerate manpagesTom Yu2012-12-171-5/+15

* Add copyright footer to HTML docsTom Yu2012-12-171-0/+1
| | | | | | | | | | | | | The technique we use for inserting the feedback link in the footer overrides the Sphinx basic/layout.html and agogo/layout.html footers in a way that prevents us from getting the copyright link footer. Copy the relevant part of the Sphinx basic/layout.html for now. Add a copyright.rst that links to mitK5license.rst. ticket: 7510 (new) target_version: 1.11 tags: pullup
* PKINIT (draft9) null ptr deref [CVE-2012-1016]Nalin Dahyabhai2012-12-141-2/+3
| | | | | | | | | | | | | | | | | | Don't check for an agility KDF identifier in the non-draft9 reply structure when we're building a draft9 reply, because it'll be NULL. The KDC plugin for PKINIT can dereference a null pointer when handling a draft9 request, leading to a crash of the KDC process. An attacker would need to have a valid PKINIT certificate, or an unauthenticated attacker could execute the attack if anonymous PKINIT is enabled. CVSSv2 vector: AV:N/AC:M/Au:N/C:N/I:N/A:P/E:P/RL:O/RC:C [tlyu@mit.edu: reformat comment and edit log message] ticket: 7506 (new) target_version: 1.11 tags: pullup
* Make the doc build quieterBen Kaduk2012-12-141-0/+1
| | | | | | | | | | | | | | Don't print out every node processed (or not processed) in the doxygen-Sphinx bridge, nor print out a summary of how many types or functions were processed. While here, tell doxygen to be quiet in its output as well, and not print out each file that is generated. It still outputs warnings, though. ticket: 7495 (new) tags: pullup target_version: 1.11
* Use an empty challenge for the password questionGreg Hudson2012-12-131-1/+1
| | | | | | | | | | | If a question's challenge is NULL, it is unnecessarily difficult for a responder callback to detect whether it was asked. So it's better to use an empty challenge when there is no challenge data to communicate. Do this for the "password" question. ticket: 7499 (new) target_version: 1.11 tags: pullup
* Update mkrel for SPHINX_ARGSTom Yu2012-12-121-2/+2
| | | | | | | | | Update mkrel so that it will explicitly set SPHINX_ARGS=-W to make warnings fatal and so that it will work in an unconfigured tree. ticket: 7497 (new) target_version: 1.11 tags: pullup
* Don't finalize libraries in static buildGreg Hudson2012-12-121-11/+13
| | | | | | | | | | | | In a build with static libraries, functions tagged with __attribute__((destructor)) may be executed in any order, not in a topologically sorted order as they are in shared libraries. This could result in libcom_err functions being invoked (from another library's finalizer) after libcom_err has been finalized, which would (at minimum) result in using a mutex after it is destroyed. To prevent this kind of problem, disable finalizers in the static build regardless of whether we have compiler or linker support for them. Reported by Mihai Serban <mihai.serban@gmail.com>.
* Regenerate checked-in man pagesBen Kaduk2012-12-112-7/+19
| | | | | | | | | | Pick up changes to kadmin.rst and krb5_conf.rst adding cross-references for account lockout and detailing parameter expansion for keytab and credentials cache names in krb5.conf ticket: 7494 (new) tags: pullup target_version: 1.11
* Update manpage version on masterBen Kaduk2012-12-1124-24/+24
| | | | | | Now that version.py is in place to update Sphinx's idea of the version number in accordance reality, update the version in the man pages that we check in; the master branch is currently a 1.12 prerelease.
* Make sphinx warnings fatal for doc buildBen Kaduk2012-12-111-2/+3
| | | | | | | | | | | | | | | We currently do not have any warnings. Let us keep it that way by making warnings fatal in maintainer-mode (and configurable on the buildslaves). Using sphinx-build -W also causes errors to be reported in the exit status and picked up by make, which is quite useful. In order to allow the build bot to use -W but end-users to not use it, SPHINX_ARGS must be passed on the command line; it cannot be set by the convenience target 'htmlsrc'. Document this. ticket: 7468 (new) tags: pullup target_version: 1.11
* Make building docs easier in an unconfigured treeBen Kaduk2012-12-111-3/+6
| | | | | | | | | | | | | Instead of requiring the user to specify srcdir, top_srcdir, PYTHON, and possibly more in the future, make an 'htmlsrc' target that does so for them. This also lets us do the clean in the same step, so that only one command is required of the user. ticket: 7491 (new) tags: pullup target_version: 1.11
* Update comments for RFC 3244 kpasswd extensionsBen Kaduk2012-12-111-3/+4
| | | | | | | | | Remove the inaccurate comments "unused" and replace them with more useful representations of what they mean. ticket: 7490 (new) tags: pullup target_version: 1.11
* Don't use $(RM) in src/doc/Makefile.inBen Kaduk2012-12-111-1/+1
| | | | | | | | | | We allow these rules to be used in an unconfigured tree, and some makes do not supply a value for RM by default. ticket: 7492 (new) subject: Doc build in unconfigured tree broken on some platforms tags: pullup target_version: 1.11
* Fix various integer issuesGreg Hudson2012-12-105-39/+19
| | | | | | | | | | | | | | | In kdc_util.c and spnego_mech.c, error returns from ASN.1 length functions could be ignored because they were assigned to unsigned values. In spnego_mech.c, two buffer size checks could be rewritten to reduce the likelihood of pointer overflow. In dump.c and kdc_preauth.c, calloc() could be used to simplify the code and avoid multiplication overflow. In pkinit_clnt.c, the wrong value was checked for a null result from malloc(), and the code could be simplified. Reported by Nickolai Zeldovich <nickolai@csail.mit.edu>. ticket: 7488
* Note notice.txt's dependency on version.pyBen Kaduk2012-12-101-1/+1
| | | | | | | | | | | | This dependency has been in effect since the notice build was changed to use the main conf.py, due to its unconditional execfile('version.py'). Adding another conditional in conf.py seems to add needless complication, it is easier to just note the dependency in the Makefile and carry on. ticket: 7470 (new) title: NOTICE build has unnoted dependency on version.py tags: pullup target_version: 1.11
* Don't return a host referral to the service realmGreg Hudson2012-12-063-1/+25
| | | | | | | | | | A host referral to the same realm we just looked up the principal in is useless at best and confusing to the client at worst. Don't respond with one in the KDC. ticket: 7483 target_version: 1.11 tags: pullup
* Fix typo for windows versionsBen Kaduk2012-12-051-1/+1
| | | | | | | | | | | We omit the patchlevel if it is zero, but the check whether the patchlevel was zero was checking the wrong variable, and thus always succeeding. ticket: 7481 (new) queue: kfw tags: pullup target_version: 1.10.4
* Access keys for the KfW ribbon interfaceBen Kaduk2012-12-051-3/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | Improve accessibility by actually enabling access keys for ribbon elements (tap alt and follow the onscreen hints for keys to press), instead of just underlining a letter in the name of each element. Supply an underlined letter in the text of each element, corresponding to this access key, even if there is not a shortcut key bound to that element. While here, fix conflicting assignment to 'R' on the 'options' tab (between "Renewable Until" and "Automatic Ticket Renewal") by making "Automatic Ticket Renewal" use 'T'. Microsoft's UI recommendations seem to say that access keys should be easy to locate when searching through the menu, and thus using the first letter of the first or second word is advisable. The Ribbon XML Reference seems to indicate that these elements should be "keytip" elements, but MSVS creates "keys" elements, which seem to work, whereas "keytip" does not. Apparently 'F' is standard for the application button menu (which contains exit). Access keys work somewhat poorly for us in this menu, as they appear on top of the text of the menu items, since we have no icons here. ticket: 7441 tags: pullup target_version: 1.10.4
* Rewrap the Leash ribbon conf fileBen Kaduk2012-12-051-1/+331
| | | | | | | | | | A big pile of XML on one line is not very readable. Use 'xmllint --format' to make things more sane. ticket: 7478 (new) queue: kfw tags: pullup target_version: 1.10.4
* Leave 'OK' button visible in Leash AboutBoxBen Kaduk2012-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | The AboutBox dialog as specified in the resource file is larger than the one we display; the dialog init routine marks several things as non-visible, moves the 'OK' button up to where the now-invisible items were, and shrinks the dialog's bounding rectangle. However, the edit boxes containing copyright and version information seem to always present as being on top of the 'OK' button, and their background causes the button to appear almost invisible with the current repositioning. To keep the 'OK' button visible, reduce the amount that it is moved (and the amount the dialog is shrunk) so that the button does not overlap with the edit box. ticket: 7443 tags: pullup target_version: 1.10.4
* Build fixes for windowsBen Kaduk2012-12-053-4/+6
| | | | | | | | | | | | Add entries to OBJS and SRCS as well as STLIBOBJS. Use KRB5_CALLCONV at function definition as well as declaration. Declare missing variable in _WIN32-conditional code. ticket: 7479 (new) tags: pullup target_version: 1.11
* Document key usage assigned number conflictZhanna Tsitkov2012-11-301-11/+10
| | | | | | | | | | | | | | | | Document the fact that the key usage type 26 is used by both KBKRB5_KEYUSAGE_PA_S4U_X509_USER_REQUEST and KRB5_KEYUSAGE_PA_S4U_X509_USER_REQUEST, while 27 - by KRB5_KEYUSAGE_PA_S4U_X509_USER_REPLY and KRB5_KEYUSAGE_PA_SAM_RESPONSE. Also, since KRB5_KEYUSAGE_PA_REFERRAL is not actually used in MIT Kerberos code and is not defined in the latest referrals draft (http://tools.ietf.org/html/draft-ietf-krb-wg-kerberos-referrals-15) mark it as "unused". ticket: 7474 tags: pullup target_version: 1.11
* Avoid redundant socket cleanup in sendto_kdc.cGreg Hudson2012-11-291-4/+0
| | | | | | | | Since r25120, kill_conn() has been responsible for closing and invalidating conn->fd. In the unlikely event that the KDC sends a TCP response to us before we send a TCP request, we were cleaning up the socket again, which is useless (though also harmless). Get rid of that code.
* Fix spin-loop bug in k5_sendto_kdcGreg Hudson2012-11-291-1/+1
| | | | | | | | | | | | In the second part of the first pass over the server list, we passed the wrong list pointer to service_fds, causing it to see only a subset of the server entries corresponding to sel_state. This could cause service_fds to spin if an event is reported on an fd not in the subset. ticket: 7454 target_version: 1.10.4 tags: pullup
* Add camellia_key_cleanupBen Kaduk2012-11-281-1/+9
| | | | | | | | Fix memory leak. ticket: 7457 tags: pullup target_version: 1.11
* Update doxygen markup in krb5.hinBen Kaduk2012-11-271-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few places were using the standard C /* comment */ form, but this is rendered poorly by doxygen through to our Sphinx bridge. Use the special /**< comment */ form to get doxygen-specific behavior. If the standard C comment form is used, the full comment (including start and end markers) is included in the value of the macro, and Sphinx then tries to treat the end of the comment as the start of inline markup with no corresponding end-string, which is a warning. Using the doxygen form of the comment, the contents of the comment are put in a separate paragraph block, which is inserted in the body of the generated RST document. The markup for krb5_rd_priv() had a line that ended with an @c markup statement without a symbol following it. This confused doxygen into not parsing any more of the comment. The beginning of the next line is a macro identifier with markup to auto-linkify it. In RST, it is not possible to have a link and a terminal font on the same text, so removing the @c is the appropriate fix. There are also eleven deprecated functions which are replaced by the krb5_c_* family of functions. However, referring to this class of functions as the "krb5_c_" class of functions results in Sphinx attempting to interpret this statement as a link to a label elsewhere in the document, and no such label exists. To avoid this warning, use "krb5_c_*" to refer to the class of functions, which is arguably more correct anyways. ticket: 7447 tags: pullup target_version: 1.11
* Make krb5_trace_info a typedefBen Kaduk2012-11-272-7/+13
| | | | | | | | | | | | | Our doxygen-to-sphinx documentation bridge only processes typedefs and not structure definitions, since we almost universally use typedefs for our data structures. krb5_trace_info is the sole exception, so bring it into the fold. While here, flesh out the comment a bit more. ticket: 7447 tags: pullup target_version: 1.11
* Remove .doctrees when cleaning src/docTom Yu2012-11-261-1/+2
| | | | | | | | | | Sphinx produces .doctree pickles that can be over 17MB with the current documentation. Remove them when running "make clean" in src/doc so that they don't pollute distribution tar files. ticket: 7461 (new) target_version: 1.11 tags: pullup
* Document krb5_get_init_creds_opt_set_in_ccacheZhanna Tsitkov2012-11-261-0/+2
| | | | | | | More specifically, document that this new API was first introduced in 1.11 ticket: 7460
* Remove broken clean_hostname trace messagesGreg Hudson2012-11-252-9/+0
| | | | | | | | | | | | The trace messages in krb5int_clean_hostname were outputting the entire contents of the output buffer (mostly uninitialized garbage) into the trace log. Since these messages were essentially redundant with messages in the callers, and were arguably at too low of a level to begin with, simply remove them. ticket: 7459 (new) target_version: 1.11 tags: pullup

* Reword krb5_unparse_name_ext doxygen markupGreg Hudson2012-11-201-5/+6
| | | | | | | | | | Avoid using asterix characters in the documentation for krb5_unparse_ext_name, since they get intepreted as markdown punctuation when translated to RST. ticket: 7452 (new) target_version: 1.11 tags: pullup
* Fix quoting issues in LDAP KDB moduleGreg Hudson2012-11-175-99/+48
| | | | | | | | | | | | | | | Modify ldap_filter_correct() to quote special characters for DN strings as well as filters, since it is already used to quote a DN string in krb5_ldap_name_to_policydn() and there's no harm in over-quoting. In krb5_ldap_put_principal(), quote the unparsed principal name for use in DNs we choose. In krb5_ldap_create_password_policy(), use the policy name for the CN of the policy entry instead of the (possibly quoted) first element of the DN. Adapted from a patch by Jim Shi <hanmao_shi@apple.com>. ticket: 7296
* Tests for kinit's detection of a keytab requestBen Kaduk2012-11-161-0/+12
