* Include external headers with #include <foo.h>Jakub Hrozek2013-10-228-23/+32
| | | | | | I find it more readable to include headers from outside the sssd tree with <foo.h>, not "foo.h". The latter should be used for in-tree headers only.
* nss: wait for initial subdomains request to finishPavel Březina2013-10-171-0/+14
| | | | | | | | | | | | AD provider downloads domain information and initalizes ID mapping during subdomains request. This information is necessary to lookup objects without POSIX attributes. We need to make sure that we postpone all responder requests until ID mapping is initialized in the provider. Resolves: https://fedorahosted.org/sssd/ticket/2092

* NSS: Failure to store entry negative cache should not be fatalJakub Hrozek2013-09-251-18/+31
| | | | | The only effect the failure to store a result to negative cache might have would be a slower lookup next time.
* NSS: Set UID and GID to negative cache after searching all domainsJakub Hrozek2013-09-251-66/+105
| | | | | | | https://fedorahosted.org/sssd/ticket/2090 Previously, when searching by UID or GID, the negative cache will only work in case the UID was searched for using fully qualified names.
* Include header file in implementation module.Lukas Slebodnik2013-09-242-0/+2
| | | | | Declarations of public functions was in header files, but header files was not included in implementation file.
* mmap_cache: Use two chains for hash collision.Lukas Slebodnik2013-09-231-18/+48
| | | | | | | | | | | | | | | | | | | | | | | struct sss_mc_rec had two hash members (hash1 and hash2) but only one next member. This was a big problem in case of higher probability of hash collision. structure sss_mc_rec will have two next members (next1, next2) with this patch. next1 is related to hash1 and next2 is related to hash1. Iterating over chains is changed, because we need to choose right next pointer. Right next pointer will be chosen after comparing record hashes. This behaviour is wrapped in function sss_mc_next_slot_with_hash. Adding new record to chain is also changed. The situation is very similar to iterating. We need to choose right next pointer (next1 or next2). Right next pointer will be chosen after comparing record hashes. Adding reference to next slot is wrapped in function sss_mc_chain_slot_to_record_with_hash Size of structure sss_mc_rec was increased from 32 bytes to 40 bytes. Resolves: https://fedorahosted.org/sssd/ticket/2049
* Revert "mmap_cache: Skip records which doesn't have same hash"Lukas Slebodnik2013-09-231-34/+2

* RESPONDER: Use right function prototypeLukas Slebodnik2013-09-202-1/+2
| | | | | | | Protype of function sss_ncache_check_netgr was different than definition of function sss_ncache_check_netgr. We did not catch it, because header file "responder/common/negcache.h" was not included in implementation file "responder/common/negcache.c"

* mmap_cache: Do not remove record from chain twiceLukas Slebodnik2013-09-091-0/+6
| | | | | | | | | | | It is not very likely, that record will have the same hash1 and hash2, but it is possible. In this situation, it does not make sense to remove record twice. Function sss_mc_rm_rec_from_chain was not robust and sssd_nss could crash in this situation. It was only possible if record was alone in chain. Resolves: https://fedorahosted.org/sssd/ticket/2049

* NSS: Descend into subdomains if enumerate=trueJakub Hrozek2013-08-281-12/+12
| | | | | | Since we now store the enumerate flag in sysdb for subdomains, we can always descend to all available subdomains and if they do not allow enumeration, simply skip them.
* mmap_cache: Use stricter check for hash keys.Lukas Slebodnik2013-08-281-4/+6
| | | | ht_size is size of hash_table in bytes, but hash keys have type uint32_t
* mmap_cache: Skip records which doesn't have same hashLukas Slebodnik2013-08-281-2/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The code uses 2 hashes for each record, but only one hash table to index them both, furthermore each record has only one single 'next' pointer. This means that in certain conditions a record main end up being on a hash chain even though its hashes do not match the hash chain. This can happen when another record 'drags' it in from another hash chain where they both belong. If the record without matching hashes happens to be the second of the chain and the first record is removed, then the non matching record is left on the wrong chain. On removal of the non-matching record the hash chain will not be updated and the hash chain will end up pointing to an invalid slot. This slot may be later reused for another record and may not be the first slot of this new record. In this case the hash chain will point to arbitrary data and may cause issues if the slot is interpreted as the head of a record. By skipping any block that has no matching hashes upon removing the first record in a chain we insure that dangling references cannot be left in the hash table Resolves: https://fedorahosted.org/sssd/ticket/2049
* sss_packet_grow: correctly pad packet length to 512BPavel Březina2013-08-281-1/+1
| | | | | | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2059 If len % SSSSRV_PACKET_MEM_SIZE == 0 or some low number, we can end up with totlen < len and return EINVAL. It also does not pad the length, but usually allocates much more memory than is desired. len = 1024 n = 1024 % 512 + 1 = 0 + 1 = 1 totlen = 1 * 512 = 512 => totlen < len len = 511 n = 511 % 512 + 1 = 511 + 1 totlen = 512 * 512 = 262144 totlen is way bigger than it was supposed to be
* PAC: Skip SIDs that cannot be resolved to domainJakub Hrozek2013-08-261-2/+4
|
* PAC: use SID instead of GID to search for groupsSumit Bose2013-08-261-48/+41
| | | | | | | With the support of POSIX IDs managed on the AD side we may find non-POSIX groups, i.e. groups which do not have a GID assigned in AD, in the PAC. Since in this case all cached groups have a SDI attribute it is more reliable to search the groups by SID instead of GID.
* PAC: do not fail if a single group cannot be added/removedSumit Bose2013-08-261-18/+31
| | | | | When processing a list of groups we try to process as much as possible only not stop on the first error.
* PAC: read user DN instead of constructing itSumit Bose2013-08-261-5/+17
| | | | | | To avoid issues with case-sensitivity it is more reliable to search the user entry in the cache and use the returned DN instead of constructing it.
* PAC: handle non-POSIX groups in cacheSumit Bose2013-08-262-11/+9
| | | | | Since the DN of the group is used to remove a membership it is not necessary to check if the GID is valid.
* PAC: do not create users with missing GIDSumit Bose2013-08-261-0/+14
| | | | | If the user entry does not exist in the cache and a primary GID cannot be found it does not make sense to create a user entry.
* PAC: if user entry already exists keep itSumit Bose2013-08-263-86/+10
| | | | | | | | | | | | | | | | | Currently the PAC responder deletes a user entry and recreates it if some attributes seems to be different. Two of the attributes where the home directory and the shell of the user. Those two attributes are not available from the PAC but where generates by the PAC responder. The corresponding ID provider might have better means to determine those attributes, e.g. read them from LDAP, so we shouldn't change them here. The third attribute is the user name. Since the PAC responder does lookups only based on the UID we can wait until the ID provider updates the entry. Fixes https://fedorahosted.org/sssd/ticket/1996

* mmap_cache: Use sss_atomic_write_s instead of write.Michal Zidek2013-08-221-2/+11
| | | | | | | | Use sss_atomic_write_s() instead of write() in sss_mc_save_corrupted(). Also unlink() the file if no data were written. It is better to use sss_atomic_write_s instead of write
* mmap_cache: Store corrupted mmap cache before resetMichal Zidek2013-08-191-0/+66
| | | | | This patch adds function to store corrupted mmap cache file to disk for further analysis.
* mmap_cache: Use better checks for corrupted mc in responderMichal Zidek2013-08-191-3/+53
| | | | | We introduced new way to check integrity of memcache in the client code. We should use similiar checks in the responder.
* mmap_cache: Off by one error.Michal Zidek2013-08-191-6/+6
| | | | | Removes off by one error when using macro MC_SIZE_TO_SLOTS and adds new macro MC_SLOT_WITHIN_BOUNDS.
* fill_initgr: add original primary GID if availableSumit Bose2013-08-191-0/+27
| | | | | | | | | | | | | In some cases when MPG domains are used the information about the original primary group of a user cannot be determined by looking at the explicit group memberships. In those cases the GID related to the original primary group is stored in a special attribute of the user object. This patch adds the GID of the original primary group when available and needed. Fixes https://fedorahosted.org/sssd/ticket/2027
* mmap_cache: Check if slot and name_ptr are not invalid.Michal Zidek2013-08-112-2/+54
| | | | | | | This patch prevents jumping outside of allocated memory in case of corrupted slot or name_ptr values. It is not proper solution, just hotfix until we find out what is the root cause of ticket https://fedorahosted.org/sssd/ticket/2018

* NSS: Clear cached netgroups if a request comes in from the sss_cacheLukas Slebodnik2013-08-083-0/+54
| | | | | | | In order for sss_cache to work correctly, we must also signal the nss responder to invalidate the hash table requests. https://fedorahosted.org/sssd/ticket/1759
* NSS: allow removing entries from netgroup hash tableLukas Slebodnik2013-08-083-1/+32
| | | | | | | | | There is a timed desctructor in the nss responder that, when the entry timeout passes, removes the netgroup from the hash table while the netgroup is freed. This patch adds a hash delete callback so that if the netgroup is removed from the hash table with hash_delete, its hash table pointer will be invalidated. Later, when the entry is being freed, the destructor won't attempt to remove it from the hash table.
* SSH: Ensure that cmd_ctx->name will not be NULL.Lukas Slebodnik2013-08-051-4/+6
| | | | | | | | If cmd_ctx->name was not initialized by sss_parse_name then copy of name will be used. https://fedorahosted.org/sssd/ticket/1970 Coverity ID: 11647
* Fix netgroup lookup when using fully qualified namePavel Březina2013-07-311-2/+2

* Netgroups should ignore the 'use_fully_qualified_names' settingStephen Gallagher2013-07-291-8/+6
| | | | | | | | | | | Netgroups often have memberNisNetgroup entries included in them that will never process correctly if we require fully-qualified names on the nested lookup. This patch alters the behavior of netgroup lookups to check *all* domains for an unqualified netgroup name, instead of only the ones not requiring fully- qualified names. https://fedorahosted.org/sssd/ticket/2013
