* UTIL: Unset O_NONBLOCK for ldap connectionLukas Slebodnik2017-01-251-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before the commit 75e66c388862a4ba05afe0791c5503226395bad0, the flag O_NONBLOCK was set only for the connect syscall in request sssd_async_connect_send -> sssd_async_connect_send. Such change was done for secrets provider. However, if ldap is compiled with gnutls it caused problems with start_tls and ldaps. There is not a problem with libldap 2.5 + gnutls because libldap is compiled with LDAP_USE_NON_BLOCKING_TLS OpenLDAP Server log: 5810cf2f connection_get(23): got connid=1042 5810cf2f connection_read(23): checking for input on id=1042 TLS: error: accept - force handshake failure: errno 11 - moznss error -12234 TLS: can't accept: TLS error -12234:SSL received an unexpected Application Data record.. 5810cf2f connection_read(23): TLS accept failure error=-1 id=1042, closing 5810cf2f connection_close: conn=1042 sd=23 sssd domain log: [simple_bind_send] (0x0100): Executing simple bind as: uid=user1,dc=example,dc=com [simple_bind_send] (0x2000): ldap simple bind sent, msgid = 2 [sdap_op_add] (0x2000): New operation 2 timeout 6 [sdap_process_result] (0x2000): Trace: sh[0x151c240], connected[1], ops[0x1515700], ldap[0x1511bd0] [sdap_process_result] (0x2000): Trace: end of ldap_result list [sdap_process_result] (0x2000): Trace: sh[0x151c240], connected[1], ops[0x1515700], ldap[0x1511bd0] [sdap_process_result] (0x0040): ldap_result error: [Can't contact LDAP server] [sdap_handle_release] (0x2000): Trace: sh[0x151c240], connected[1], ops[0x1515700], ldap[0x1511bd0], destructor_lock[0], release_memory[0] [remove_connection_callback] (0x4000): Successfully removed connection callback.

* WATCHDOG: Avoid non async-signal-safe from the signal_handlerFabiano Fidêncio2017-01-251-22/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While debugging rhbz#1396912 a deadlock on sssd_be was noticed[0] and it's been caused by the use of non async-signal-safe functions from the signal_handler (please, see man 7 signal for more info about which are the async-signal-safe functions that can be used). In order to work this situation around a pipe has been added to the watchdog_ctx structure and, in case of clock screw, a single byte is written to this pipe (which is an async-signal-safe operation) and the logic currently done by the timer handler to reset the watchdog will be done inside the fd handler in a safe way. With this patch we ended up losing some debug messages as orderly_shutdown() has been replaced by kill(-getpgrp(), SIGTERM) (or _exit(1) considering the cases where setting up the process group during the server_setup() has failed). Personally I don't think is worth the trouble to try to log those messages properly in this specific case. It's really worth to mention that a proper fix the clock screw situation should be implemented on samba's side, by having tevent using monotonic (or boottime) clock.

* SERVER: Set the process group during server_setup()Fabiano Fidêncio2017-01-251-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | By calling setpgid() in server_setup() we are able to kill the process in the watchdog by simply doing kill(-getpid(), SIGTERM). However, in order to have it working properly the SELinux policy for SSSD has to be updated and unless SSSD is ran with SELinux on permissive mode, each of the responders and the monitor will trigger a similar message: Jan 09 14:31:50 client1.ipa.example audit[11630]: AVC avc: denied { setpgid } for pid=11630 comm="sssd_pac" scontext=system_u:system_r:sssd_t:s0 tcontext=system_u:system_r:sssd_t:s0 tclass=process permissive=0 It's important to say that till SELinux policy is fixed, we might end up leaking some processes.

* UTIL: Introduce --dbus-activated cmd option for respondersFabiano Fidêncio2017-01-232-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Similarly to the --socket-activated cmd option, --dbus-activated cmd option is going to be used for dbus-activated responders in order to easily setup a timeout to shutdown the idle responder in case it has been socket activated and is idle. This option has been encapsulated on is_dbus_activated() function, which will always return "false" when called on platforms where systemd is not supported. For now any of the services are taking advantage of this newly introduced option/function, but later on in this series it's going to be used. In order to use it, just add SSSD_RESPONDER_OPTS to the poptOption structure.

* sss_ptr_hash_delete_all: use unsigned long intSumit Bose2016-12-221-2/+2
| | | | | | | | | hash_values() expects a pointer to unsigned long int as second argument. Using size_t instead causes a 'from incompatible pointer type' compiler error on e.g. 32bit platforms because size_t is 32bits here while unsigned long int is 64bits.

* nss: rewrite nss responder so it uses cache_reqPavel Březina2016-12-192-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given the size of the current nss responder it was quite impossible to simply switch into using the cache_req interface, especially because most of the code was duplication of cache lookups. This patch completely rewrites the responder from scratch. The amount of code was reduced to less than a half lines of code with no code duplication, better documentation and better maintainability and readability. All functionality should be intact. *Code organization* All protocol (parsing input message and send a reply) is placed in nss_protocol.c. Functions that deals with creating a reply packet are placed into their specific nss_protocol_$object.c files. All supported commands are placed into nss_cmd.c. Functions that deals with cache req are in nss_get_object.c and nss_enum.c. *Code flow for non-enumeration* An nss_getby_$input-type is called for each non-enumeration command. This function parses the input message, creates a cache_req_data structure and issues nss_get_object that calls cache_req. When this request is done nss_getby_done make sure a reply is sent to the client. *Comments on enumeration* I made some effort to make sure enumeration shares the same code for users, groups, services and netgroups. Netgroups now uses nss negative cache instead of implementing its own. Resolves: https://fedorahosted.org/sssd/ticket/3151 Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
