* Fix crash on invalid DIR ccache primary fileGreg Hudson2012-06-251-2/+2
| | | | | | | | | | If read_primary_file() fails with an error other than ENOENT, abort cache resolution rather than dereferencing a null pointer. Reported by Oliver Loch. ticket: 7185 target_version: 1.10.3 tags: pullup
* Eliminate trailing whitespace in trval outputGreg Hudson2012-06-225-1254/+1259
| | | | | | | | Modify the trval output slightly so that the reference trval output files don't containing trailing whitespace, to make them friendlier to our git hooks. (The pkinit and ldap trval reference files now contain a leading blank line, which isn't very elegant, but avoiding that requires too much Makefile.in complexity.) Also correct a typo.
* Simplify acquire_cred.cGreg Hudson2012-06-221-109/+48
| | | | | | struct acquire_cred_args was used purely to pass arguments to acquire_cred (a static function), and had no advantages for that purpose over positional arguments.
* Fix config check in krb5_cccol_have_contentGreg Hudson2012-06-221-1/+1
| | | | | | | krb5_is_config_principal should be invoked on creds.server, not creds.client. ticket: 7173
* Limit size of lookaside cacheGreg Hudson2012-06-221-14/+25
| | | | | | | | Add a preprocessor constant LOOKASIDE_MAX_SIZE (defaulting to 10MB) which limits the total size of the lookaside cache entries. Purge stale entries in kdc_insert_lookaside instead of kdc_check_lookaside, and when doing so, continue purging non-stale entries until the total cache size (including the new entry) is within the size constraint.
* Flatten KDC lookaside cache entriesGreg Hudson2012-06-221-9/+11
| | | | | Use krb5_data structures instead of pointers in the entry structure, reducing the number of memory allocations.
* Handle PKINIT DH replies with no certsGreg Hudson2012-06-221-1/+8
| | | | | | | | | | | | | | | If a PKINIT Diffie-Hellman reply contains no certificates in the SignedData object, that may be because the signer certificate was a trust anchor as transmitted to the KDC. Heimdal's KDC, for instance, filters client trust anchors out of the returned set of certificates. Match against idctx->trustedCAs and idctx->intermediateCAs to handle this case. This fix only works with OpenSSL 1.0 or later; when built against OpenSSL 0.9.x, the client will still require a cert in the reply. Code changes suggested by nalin@redhat.com. ticket: 7183

* Document how to free krb5_cc_get_full_name resultGreg Hudson2012-06-202-2/+4
| | | | | | | | Also, in klist, use the appropriate libkrb5 free functions for krb5_cc_get_full_name and krb5_unparse_name_results. Reported by Kevin Wasserman. ticket: 7179
* Minor reformating for better Sphinx HTML outputZhanna Tsitkov2012-06-192-52/+27
| | | | No content was changed.
* Remove CRs from options2configure.rstGreg Hudson2012-06-181-402/+402
| | | | | options2configure.rst had CRLF newlines, and should have LF newlines like everything else.
* Document version for new API functionsZhanna Tsitkov2012-06-151-0/+4

* Fail from gss_acquire_cred if we have no credsGreg Hudson2012-06-152-0/+15
| | | | | | | | If a caller tries to acquire krb5 initiator creds with no desired name and we have no credentials in the cache collection, fail from gss_acquire_cred intead of deferring until gss_init_sec_context. ticket: 7160
* Add krb5_cccol_have_content APIGreg Hudson2012-06-157-2/+63
| | | | | | | Add a new API to determine whether any krb5 credentials are available in the ccache collection. Add tests to t_cccol.py. ticket: 7173 (new)

* Remove krb5int_cc_os_default_nameGreg Hudson2012-06-112-22/+0
| | | | | krb5int_cc_os_default_name has been unused since #6955 removed the call to it in cccursor.c. Get rid of it.
* Clean up default_an_to_ln and fix a minor leakGreg Hudson2012-06-081-35/+23
| | | | | | | The default realm could be leaked if the principal had the wrong number of components. Reported by Russ Allbery. ticket: 7161
* Remove big-endian gss-krb5 supportGreg Hudson2012-06-0811-102/+32
| | | | | | | | The big_endian flag in krb5_gss_ctx_id_rec is there for interoperability with a really ancient implementation which we believe is no longer in use. Get rid of it and the code to handle it. ticket: 7166 (new)
* Update Build Kerberos V5 doc sectionZhanna Tsitkov2012-06-082-25/+32
| | | | ticket: 7126
* Fix memory leak in dbentry_supports_enctype in KDCGreg Hudson2012-06-071-9/+8
| | | | The etypes list was never freed. Also use k5_etypes_contains.
* Rename and add to etype utility functionsGreg Hudson2012-06-0711-32/+37
| | | | | | | Rename krb5int_count_etypes and krb5int_copy_etypes to have k5_ prefixes, and make them available outside of libkrb5 (but not part of the public API). Add k5_etypes_contains to search an etype list, and use it in krb5_is_permitted_enctype.
* Remove krb5_is_permitted_enctype_extGreg Hudson2012-06-072-42/+0
| | | | | It's an internal function (not in krb5.h or the libkrb5 export list) and nothing uses it.
* Don't free caller's principal in vfy_incredsGreg Hudson2012-06-061-1/+0
| | | | | | | | #7125 took out the copy of the krb5_verify_init_creds server argument but left in the corresponding free, so it was freeing a caller-owned principal. Reported by Russ Allbery. ticket: 7162
* Try to make t_trace.c output consistentGreg Hudson2012-06-063-16/+14
| | | | | | Attempt to choose tracing inputs in t_trace.c which will produce consistent output across platforms and logins. Re-enable the comparison against the reference file.
* Add control over session key enctype negotiationNicolas Williams2012-06-0614-60/+161
| | | | | | | | | | | | | | | | | | | Adds a principal string attribute named "session_enctypes" which can specify what enctypes the principal supports for session keys. (For what it's worth, this actually allows one to list des-cbc-md5 as a supported session key enctype, though obviously this hardly matters now.) Add a [realms] section parameter for specifying whether to assume that principals (which lack the session_enctypes attribute) support des-cbc-crc for session keys. This allows those who still need to use allow_weak_crypto=true, for whatever reason, to start reducing the number of tickets issued with des-cbc-crc session keys to clients which still give des-cbc-crc preference in their default_tgs_enctypes list. [ghudson@mit.edu: Miscellaneous edits, cleanups, and fixes; refactored test script; documented session_enctypes attribute]
* Allow daemon debugging in k5test.pyGreg Hudson2012-06-061-6/+8
| | | | | | | Allow --debug to be used for commands which start daemons, to make it easier to debug startup issues. After debugging a daemon, the script will exit, since the daemon won't be running after the debugging session is over.
* Fix k5test.py hostname canonicalizationGreg Hudson2012-06-051-2/+1
| | | | | | | | | | r25844 (#7124) stopped using AI_ADDRCONFIG when canonicalizing hostnames in sn2princ. So we need to also stop using it in k5test.c's _get_hostname() or we could come up with a different result on a system where forward and reverse resolution via IPv4 and IPv6 produce different results. That in turn causes a t_gssapi.py test (the one using the un-canonicalized hostname) to fail, because libkrb5 looks for a different host principal than k5test.py put in the keytab.
* Fix uninitialized memory errors in t_trace.cGreg Hudson2012-06-051-1/+4
|
* Disable trace test comparison for nowGreg Hudson2012-06-051-1/+2
| | | | | | The t_trace output isn't consistent from run to run. To fix "make check", disable the comparison against the reference file until we can make the output consistent.
* Fix trace log unit testGreg Hudson2012-06-042-1/+53
| | | | | | | Only use common denominator Bourne shell syntax for exporting environment variables. Don't rely on /dev/stdout working. Compare the output with a reference file to detect changes, instead of just sending it to stdout.
* Fix -DDEBUG compilation errorsHenry B. Hotz2012-06-045-3/+6

* Fail from gss_acquire_cred if we have no keytabGreg Hudson2012-06-032-0/+15
| | | | | | | | If a caller tries to acquire krb5 acceptor creds with no desired name and we have no keytab keys, fail from gss_acquire_cred instead of deferring until gss_accept_sec_context. ticket: 7159 (new)
* Use first mech's status in gss_acquire_credGreg Hudson2012-06-031-3/+11
| | | | | | | | | | | If we can't acquire creds for any mech in gss_acquire_cred, return the status of the first mech instead of the last mech, as it's more useful in the typical case (where the first mech is krb5 and the last mech is SPNEGO). This error reporting is not ideal when the user was expecting to use some mech other than krb5, but it's about as good as things were prior to #6894. ticket: 6973
* Improve error message from krb5_kt_have_contentGreg Hudson2012-06-031-2/+10

* Remove outdated comment in k5test.pyGreg Hudson2012-06-031-17/+0
|
* Add krb5_kt_have_content APIGreg Hudson2012-06-026-0/+44
| | | | | | | | | | | | | Add the krb5_kt_have_content API from Heimdal, which can be used to test whether a keytab exists and contains entries. Add tests to t_keytab.c. There is a deviation from Heimdal in the function signature. Heimdal's signature returns a krb5_boolean at the moment, because the Heimdal implementation actually returns a krb5_error_code. These are generally the same type anyway (int). ticket: 7158 (new)
* Tighten up error checking in t_keytab.cGreg Hudson2012-06-021-29/+16
| | | | | | | When checking for specific error codes, using CHECK() meant that we wouldn't properly fail if we got error code 0. Define and use a CHECK_ERR() to test for a specific error code, and define CHECK() in terms of it.
* Sphinx HTML: Collapse l4 in ToC in the sidebarZhanna Tsitkov2012-06-013-13/+35
| | | | | | | Also, - resize the width of the document vs sidebar; - decrease padding in the sidebar; - mark current l2 in ToC in the sidebar.
* Use correct profile var in krb5_get_tgs_ktypesGreg Hudson2012-06-011-1/+1
| | | | | | | | | | | In r21879, when we converted to using KRB5_CONF macros for profile variable names, we made a typo in krb5_get_tgs_ktypes and erroneously started using default_tkt_enctypes instead of default_tgs_enctypes for TGS requests. Fix the typo and return to the documented behavior. ticket: 7155 target_version: 1.10.3 tags: pullup
* Use a hash table in the KDC lookaside cacheGreg Hudson2012-05-304-110/+160
| | | | | | | Add a hash table to kdc/replay.c for fast lookup of incoming packets. Continue to keep a time-ordered linked list of all entries for fast expiry of stale entries. The preprocessor constant LOOKASIDE_HASH_SIZE can be used to change the size of the hash table.
* Add a copy of the BSD <sys/queue.h> as k5-queue.hGreg Hudson2012-05-303-2/+752
| | | | | queue.h implements various types of linked lists as cpp macros, without needing any library support.
* Null pointer deref in kadmind [CVE-2012-1013]Richard Basch2012-05-291-1/+1
| | | | | | | | | | | | | | | | The fix for #6626 could cause kadmind to dereference a null pointer if a create-principal request contains no password but does contain the KRB5_KDB_DISALLOW_ALL_TIX flag (e.g. "addprinc -randkey -allow_tix name"). Only clients authorized to create principals can trigger the bug. Fix the bug by testing for a null password in check_1_6_dummy. CVSSv2 vector: AV:N/AC:M/Au:S/C:N/I:N/A:P/E:H/RL:O/RC:C [ghudson@mit.edu: Minor style change and commit message] ticket: 7152 target_version: 1.10.2 tags: pullup

* Fix S4U user identification in preauth caseGreg Hudson2012-05-241-4/+2
| | | | | | | | | | | | | | | | | | | | | | | In 1.10, encrypted timestamp became a built-in module instead of a hardcoded padata handler. This changed the behavior of krb5_get_init_creds as invoked by s4u_identify_user such that KRB5_PREAUTH_FAILED is returned instead of the gak function's error. (Module failures are not treated as hard errors, while hardcoded padata handler errors are.) Accordingly, we should look for KRB5_PREAUTH_FAILED in s4u_identify_user. On a less harmful note, the gak function was returning a protocol error code instead of a com_err code, and the caller was testing for a different protocol error code (KDC_ERR_PREAUTH_REQUIRED) which could never be returned by krb5_get_init_creds. Clean up both of those by returning KRB5_PREAUTH_FAILED from the gak function and testing for that alone. Reported by Michael Morony. ticket: 7136 target_version: 1.10.2 tags: pullup
* Convert DEBUG_REFERRALS to TRACE_* frameworkW. Trevor King2012-05-237-74/+68
| | | | | | | | | The referrals debugging code under DEBUG_REFERRALS ceased building correctly at some point. Convert this debugging code to use the tracing framework instead, including adding new trace macros to k5-trace.h. ticket: 7151
* Add tests for trace.c formattingW. Trevor King2012-05-232-2/+259
| | | | | | This improves the previously minimal test coverage of "trace.c". ticket: 7151
* Add support for "{ptype}" trace format specifierW. Trevor King2012-05-232-0/+25
| | | | | | | Add the "{ptype}" trace format specifier, for principal name types. Also document the new option in the "k5-trace.h" comments. ticket: 7151
