* dyndns: Add checks for NULLMichal Židek2016-07-131-0/+20
| | | | | | | | | | | | | | Fixes: https://fedorahosted.org/sssd/ticket/3076 We segfaulted in this area once. This patch makes the code more defensive and adds some DEBUG messages. Normally the structures are filled in online and/or resolve callbacks. Reviewed-by: Pavel Březina <pbrezina@redhat.com>
* PROVIDERS: Setting right {u,g}id if unprivilegedPetr Cech2016-07-121-0/+2
| | | | | | | | | | | | | | | be_ctx had talloc_zero() initialized uid and gid which was used in function dp_init(). Therefore back-end was every time started as root and therefore non-root responders could not communicate with back-end due to wrong permission of unix sockets. This patch sets right uid and gid to data-providers if sssd runs as non-root user. Resolves: https://fedorahosted.org/sssd/ticket/3077 Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

* LDAP: Qualify user and group names when saving the sudo usersJakub Hrozek2016-07-071-0/+62
| | | | | | | | | | | | | | | If the sudoUser values we fetch from LDAP correspond to a user or a group name per: http://www.sudo.ws/man/1.8.14/sudoers.ldap.man.html then we parse the usernames into (name,domain) tuples and store them qualified. This patch not only makes the sudo provider work with qualified names, but also makes it possible to use qualified names on the LDAP side, allowing for example AD users from different domains to access sudo rules.

* SIMPLE: Make the simple access provider work with qualified namesJakub Hrozek2016-07-071-19/+19
| | | | | | | | | | | | | | | | This patch adds a behaviour change to the simple access provider - the simple access list is parsed on the access check itself, which is when the name contexts of all domains have already been established and we are already able to parse the names in the config files with sss_parse_names. We need to support "input names" in the simple access provider because it needs to support flat names which rely on knowing the details about a domain. The simple_access_obtain_filter_lists is intentionally made non-static in order to be called from tests which initialize the name contexts on their own. Reviewed-by: Sumit Bose <sbose@redhat.com>

| | | | | | | | | | | | | Functions tevent_req_is_error and _tevent_req_error use type uint64_t for error code. SSSD uses errno_t which is an alias for int. Therefore complier assumes that macro TEVENT_REQ_RETURN_ON_ERROR can return 0 due to implicit down casting from uint64_t -> int.

* LDAP: Shortcut looking up for group members soonerJakub Hrozek2016-06-231-10/+53
| | | | | | | | | | | | | | | | This patch is a performance enhancement. When looking for entries to refresh, we always looked up all members in the cache, even if we ended up dereferencing the whole group. If we are about to try dereference, it makes sense to shortcut the lookups after the dereference threshold is reached. In that case, the split_members function returns a special error code and the caller just dereferences the whole group. Only if dereference fails, we fall back to looking up all members so that we can look them up one-by-one. Also adds an integration test to make sure the dereference code works.

| | | | | | | | | | | | | | | | This is just a beginning of new responder interface to data provider and it is just to make the client registration work. It needs further improvement. The idea is to take the existing interface and make it work better with further extensions of data provider.

It also doesn't work well with integration into tevent-made responders.
