* selinux: Delete existing user mapping on empty defaultJakub Hrozek2015-03-041-6/+8
| | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2587 The case of SELinux default user mapping being an empty string is valid, it should translate into "pick the default context on the target machine". In case the context is empty, we need to delete the per-user mapping from the SELinux database to make sure the default is used.

| | | | | | | | | | https://fedorahosted.org/sssd/ticket/2300 The list of SELinux mapping orders was allocated on tmp_ctx and parsed into an array. The array itself was correctly allocated on mem_ctx but its contents remained on tmp_ctx, leading to a use-after-free error. This patch fixes the memory hierarchy so that both the array and its contents are allocated on mem_ctx.

* LDAP: sdap_id_ctx might contain several connectionsJakub Hrozek2013-06-071-1/+2
| | | | | | | | | | | | | | | | | | | With some LDAP server implementations, one server might provide different "views" of the identites on different ports. One example is the Active Directory Global catalog. The provider would contact different view depending on which operation it is performing and against which SSSD domain. At the same time, these views run on the same server, which means the same server options, enumeration, cleanup or Kerberos service should be used. So instead of using several different failover ports or several instances of sdap_id_ctx, this patch introduces a new "struct sdap_id_conn_ctx" that contains the connection cache to the particular view and an instance of "struct sdap_options" that contains the URI. No functional changes are present in this patch, currently all providers use a single connection. Multiple connections will be used later in the upcoming patches.
* Fix broken build with selinux.Lukas Slebodnik2013-05-141-1/+3
| | | | | | | | | Header file selinux/selinux.h was removed in commit 245cc346 from file ipa_selinux.c, because it breaks build without selinux. But new error was introduced. This patch fixes compilation with selinux and include header file selinux/selinux.h only if both macros exist HAVE_SELINUX and HAVE_SELINUX_LOGIN_DIR. Now ipa_selinux.c should be correctly built with and without selinux.
* Fixes compilation without selinux.Lukas Slebodnik2013-05-131-1/+0
| | | | | | | | Compilation fail if ./configure is called with arguments --with-selinux --with-semanage and selinux header files are not installed. We didn't not catch this in fedora, because krb5-devel depends on libselinux-devel, but other distribution can package it differently. And API from selinux.h is not used in file ipa_selinux.c

* Move SELinux processing to provider.Michal Zidek2013-03-191-31/+381
| | | | | | | | | | | | The SELinux processing was distributed between provider and pam responder which resulted in hard to maintain code. This patch moves the logic to provider. IT ALSO REQUIRES CHANGE IN THE SELINUX POLICY, because the provider also writes the content of selinux login file to disk (which was done by responder before). https://fedorahosted.org/sssd/ticket/1743
