* Use sss_ldap_err2string() instead of ldap_err2string()sssd-1.5.1-51.el6Pavel Březina2011-09-122-3/+19
| | | | | | | | | | sss_ldap_err2string() - function created https://fedorahosted.org/sssd/ticket/986 sss_ldap_err2string() - ldap_err2string() to sss_ldap_err2string() https://fedorahosted.org/sssd/ticket/986
* Provide python bindings for the HBAC evaluator libraryJakub Hrozek2011-08-042-0/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes for python HBAC bindings These changes were proposed during a review: * Change the signature of str_concat_sequence() to const char * * use a getsetter for HbacRule.enabled to allow string true/false and integer 1/0 in addition to bool * fix a minor memory leak (HbacRequest.rule_name) * remove overzealous discard consts Fix python HBAC bindings for python <= 2.4 Several parts of the HBAC python bindings did not work with old Python versions, such as the one shipped in RHEL5. The changes include: * a compatibility wrapper around python set object * PyModule_AddIntMacro compat macro * Py_ssize_t compat definition * Do not use PyUnicode_FromFormat * several function prototypes and structures used to have "char arguments where they have "const char *" in recent versions. This caused compilation warnings this patch mitigates by using the discard_const hack on python 2.4 Remove dead code from python HBAC bindings https://fedorahosted.org/sssd/ticket/935 Handle allocation error in python HBAC bindings https://fedorahosted.org/sssd/ticket/934 HBAC rule validation Python bindings https://fedorahosted.org/sssd/ticket/943
* Fix TLS/SSL validation after switch to ldap_init_fdSumit Bose2011-07-132-0/+368
| | | | | | | | | | | | | | Add sockaddr_storage to sdap_service Add sdap_call_conn_cb() to call add connection callback directly Use name based URI instead of IP address based URIs Use ldap_init_fd() instead of ldap_initialize() if available Do not access state after tevent_req_done() is called. Call ldap_install_tls() on ldaps connections

* Validate user supplied size of data itemsSumit Bose2011-01-111-0/+5
| | | | | | Specially crafted packages might lead to an integer overflow and the parsing of the input buffer might not continue as expected. This issue was identified by Sebastian Krahmer <krahmer@suse.de>.

* Always use uint32_t for UID/GID numbersJakub Hrozek2010-10-262-4/+4
|
* Write log opening failures to the syslogStephen Gallagher2010-10-191-0/+3
| | | | | If there is a problem with reopening the logs, it can be an audit trail issue.
* Use unsigned long for conversion to id_tJakub Hrozek2010-10-181-4/+4
| | | | | | | | We used strtol() on a number of places to convert into uid_t or gid_t from a string representation such as LDAP attribute, but on some platforms, unsigned long might be necessary to store big id_t values. This patch converts to using strtoul() instead.
* Add a missing include fileSumit Bose2010-10-131-0/+1
| | | | | strcasecmp() is defined in strings.h which might not be included under certain conditions.
* Add common hash table setupStephen Gallagher2010-10-082-0/+58
| | | | | sss_hash_create() produces a dhash table living in the talloc hierarchy.

| | | | | | Three assignments deleted, two return code inspection added. Also found and fixed one critical bug caused by dead assignment. Ticket: #590
* Password obfuscation utility functionsJakub Hrozek2010-09-083-0/+510
| | | | | | | Adds two utility functions to obfuscate a password and inverse to extract the cleartext password back. So far, only NSS-based implementation is provided.
* Add safe copy/move macros for uint16_tJakub Hrozek2010-09-081-1/+11
|
* Move crypto functions into its own subdirJakub Hrozek2010-09-085-42/+109
| | | | | | A refactoring patch that creates a common util/crypto subdir with per-implementation subdirectories for each underlying crypto library supported by SSSD.
* Add dup_string_list() utility functionStephen Gallagher2010-08-032-0/+37
|
* Add diff_string_lists utility functionStephen Gallagher2010-08-032-0/+209
| | | | Includes a unit test
* Validate keytab at startupJakub Hrozek2010-08-032-0/+162
| | | | | | | | In addition to validating the keytab everytime a TGT is requested, we also validate the keytab on back end startup to give early warning that the keytab is not usable. Fixes: #556
* Add log notifications for startup and shutdown.Stephen Gallagher2010-07-091-1/+4
|
* Add sss_log() functionStephen Gallagher2010-07-092-0/+81
| | | | | Right now, this log function writes to the syslog. In the future, it could be modified to work with ELAPI or another logging API.
* Resend SIGINT as SIGTERM in servicesJakub Hrozek2010-06-281-0/+3

| | | | Fixes: #541
* Fix misuse of errno in find_uid.cStephen Gallagher2010-06-101-17/+26
|
* Properly handle read() and write() throughout the SSSDStephen Gallagher2010-06-103-12/+57
| | | | | | | We need to guarantee at all times that reads and writes complete successfully. This means that they must be checked for returning EINTR and EAGAIN, and all writes must be wrapped in a loop to ensure that they do not truncate their output.
* Move parse_args() to utilSumit Bose2010-05-272-0/+101

* Add ldap_krb5_ticket_lifetime optionSumit Bose2010-05-161-0/+5

* Clean up kdcinfo and kpasswdinfo files when exitingStephen Gallagher2010-05-072-1/+2
|
* Support SRV servers in failoverJakub Hrozek2010-04-301-0/+16
| | | | | | | | | | | | | | | Adds a new failover API call fo_add_srv_server that allows the caller to specify a server that is later resolved into a list of specific servers using SRV requests. Also adds a new failover option that specifies how often should the servers resolved from SRV query considered valid until we need a refresh. The "real" servers to connect to are returned to the user as usual, using the fo_resolve_service_{send,recv} calls. Make SRV resolution work with c-ares 1.6
* Avoid accessing half-deallocated memory when using talloc_zfree macro.eindenbom2010-04-161-1/+5
| | | | | | The correct memory deallocation sequence is: - clear pointer to memory first - then deallocate memory
* Protect against check-and-open race conditionsStephen Gallagher2010-04-062-28/+77
| | | | | | | | | | | | | | | | | There is a small window between running lstat() on a filename and opening it where it's possible for the file to have been modified. We were protecting against this by saving the stat data from the original file and verifying that it was the same file (by device and inode) when we opened it again, but this is an imperfect solution, as it is still possible for an attacker to modify the permissions during this window. It is much better to simply open the file and test on the active file descriptor. Resolves https://fedorahosted.org/sssd/ticket/425 incidentally, as without the initial lstat, we are implicitly accepting symlinks and only verifying the target file.
* Allow arbitrary-length PAM messagesStephen Gallagher2010-03-251-3/+8
| | | | | | | | | The PAM standard allows for messages of any length to be returned to the client. We were discarding all messages of length greater than 255. This patch dynamically allocates the message buffers so we can pass the complete message. This resolves https://fedorahosted.org/sssd/ticket/432
