* Bug 630097 - (cov#15473) NULL dereference in ResHashCreate()Nathan Kinder2010-09-151-2/+2
| | | | | | | If there is a problem allocating pResHash, we jump to the error label. The error label then dereferences pResHash to do a deep free, but it doesn't check if pResHash is NULL first. We need to check if pResHash is NULL before dereferencing it.
* Bug 630097 - (cov#15465) Null dereference in USN codeNathan Kinder2010-09-151-1/+1
| | | | | | | At the end of the for loop, be will be NULL if we never find a valid be->be_usn_counter. This will cause us to dereference a NULL pointer at the next if statement after the for loop. We need to check if be is NULL before dereferencing it.
* Bug 630097 - (cov#15464) NULL dereference in repl codeNathan Kinder2010-09-151-1/+1
| | | | | | | | If the attr parameter that is passed to my_ber_scanf_attr() is NULL, we jump to the loser label where we clean up memory we may have allocated. We dereference attr without first checking if it is NULL in this clean-up code. We need to check if attr is NULL before dereferencing it.
* Bug 630097 - (cov#15463) Remove NULL check in referint pluginNathan Kinder2010-09-151-3/+1
| | | | | | | | | | | | Coverity believes that search_result_pb can be NULL since we check if it is NULL before freeing the internal search results. If this was true, there would be a NULL dereference issue when we call slapi_pblock_get(). We are guaranteed that search_result_pb is non-NULL after slapi_pblock_new() is called since the server would exit if it was unable to allocate memory. We should remove the NULL check before freeing the internal search results.
* Bug 630097 - (cov#15462) NULL dereference in mep_modrdn_post_op()Nathan Kinder2010-09-151-0/+1
| | | | | | | | | | | | | If we fail to fetch the postop entry for a modrdn operation in the Managed Entry Plug-in, we end up passing a NULL pointer to slapi_entry_attr_get_charptr(). This function dereferences the entry without checking if it is NULL first. The mep_modrdn_post_op() function should just return if we are unable to fetch the postop entry. I believe that this issue could trigger a crash when chain-on-update is configured and a modrdn operation is chained. There is no postop entry in this case.
* Bug 630097 - (cov#15461) Remove unnecessary NULL check in DNANathan Kinder2010-09-151-1/+1
| | | | | | | | It is not necessary to check if config_entry->types is NULL since it is guaranteed to be non-NULL by dna_parse_config_entry() when it creates config_entry. Coverity thinks that a NULL derefence is possible since we are checking if config_entry->types is NULL. We should remove this NULL check.
* Bug 630097 - (cov#15460) NULL deference in ACL URL codeNathan Kinder2010-09-151-2/+2
| | | | | | When parsing a URL without a host or port present, we can dereference a NULL pointer. We need to check if hostport is NULL before dereferencing it.
* Bug 630097 - (cov#12182,12183) NULL dereference in import codeNathan Kinder2010-09-151-2/+2
| | | | | | The entry pointer that is passed to slapi_entry_attr_find() is dereferenced by that function without a check for NULL. We should check if ep->ep_entry is NULL before calling slapi_entry_attr_find().
* Bug 630097 - (cov#12148) NULL dereference in ruvInit()Nathan Kinder2010-09-151-3/+5
| | | | | | We need to check if ruv is NULL before dereferencing it. The assertion will not help us here in an optimized build, so an explicit NULL check will keep us from crashing.
* Bug 630097 - (cov#12143) NULL dereference in cos cache codeNathan Kinder2010-09-151-2/+8
| | | | | The tmpDn pointer is deferenced before checking if it is NULL. We need to check if it is NULL first.
* Bug 630097 - (cov#11964) Remove dead code from libaccessNathan Kinder2010-09-151-196/+0
| | | | | | | | The libaccess library has some dead functions it it. One of these functions was flagged as having a NULL pointer dereference issue by Coverity. The problem function is unused, so it should be removed. There are also a number of other unused functions in the same source file that should be removed.
* Bug 630097 - (cov#11946) NULL dereference in ResHashCreate()Nathan Kinder2010-09-151-1/+1
| | | | | | | | If we jump to the error label due to an error allocating memory for pResHash->treelist, we try to do a free of pResHash->treelist->vlist without checking if pResHash->treelist is NULL. We need to perform this NULL check before dereferencing pResHash->treelist.
* Bug 630097 - (cov#11938) NULL dereference in mmldifNathan Kinder2010-09-151-1/+1
| | | | | | | There is a chance that we can deference a NULL pointer in the mmldif code. If "(numb > tot_b)" is true, it is not guaranteed that "a" is non-NULL. We need to check if "a" is NULL before dereferencing it in the "(cmp < 0)" case.
* Bug 630097 - (cov#11933) Fix NULL dereference in schema codeNathan Kinder2010-09-151-1/+3
| | | | | | | | | | | | There is a possibility of deferencing prevocp when it is NULL the second time through the loop if the first pass was not a standard objectclass definition and tmpocp != curlisthead. I don't think that this issue is possible unless some other thread was able to modify tmpocp->oc_next between where curlisthead is set (schema.c:2654) and where nextocp is set (schema.c:2658) the first time through the loop. That said, I see no harm in checking if prevocp is NULL before attempting to dereference it.
* Bug 631862 - crash - delete entries not in cache + referintNoriko Hosoi2010-09-145-50/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://bugzilla.redhat.com/show_bug.cgi?id=631862 Resolves: bug 631862 Bug Description: crash - delete entries not in cache + referint Reviewed by: rmeggins and nhosoi Branch: master Fix Description: When deleting an entry, the referential integrity (referint) plugin does an internal search to find references to this entry (e.g. in group entries) and removes them. The search code wants to ensure that the entrydn attribute is present in the entry when using entryrdn (subtree rename). The search code sets a flag to tell the id2entry code to add the entrydn attribute if it is not present. However, it was doing this to an entry in the cache, which may be in use by another thread. The solution is to add the entrydn attribute before adding the entry to the cache. In the id2entry code, this is after the entry has been read from the id2entry db successfully, but before the entry is added to the cache. In the LDAP ADD code, this is done when the other computed operational attributes are added to the new entry. In addition to the above fix by rmeggins@redhat.com, following changes are made: 1) entrydn attribute is always added to the entry in memory before putting it in the entry cache, and the attribute is removed before writing the entry to the database. 2) eliminating id2entry_ext, which was introduced to pass flags, but it is no longer needed since only a flag ID2ENTRY_ADD_ENTRYDN was removed. Platforms tested: RHEL5 x86_64 Flag Day: no Doc impact: no
* Only check modrdn ops for backend/suffix correctness if not the default backendRich Megginson2010-09-131-2/+3
| | | | | | | | | | | | | | | | The function slapi_mapping_tree_select_and_check() is only called for modrdn operations, to make sure we are not attempting to rename a suffix or move an entry from one backend to another. This defeats datainterop plugins that may want to perform some other operation in these cases. If the target suffix/backend is not found, the default backend is used. If the default backend is being used, don't check for all errors, just allow the operation to pass through to the preop plugins. Need to make sure this doesn't cause problems if 1) null suffix is not used - entry really is bogus or doesn't exist 2) null suffix is being used but entry belongs to another null suffix or is really bogus Reviewed by: nhosoi (Thanks!) Tested on: Fedora 14 x86_64

* agmtlist_shutdown (repl5_agmtlist.c) had an illegal access defect.Noriko Hosoi2010-09-131-3/+5
| | | | | | | Object ro is freed in objset_next_obj and next object is returned if any. After ro is released, it was used to get agreement data. This patch moves the location of objset_next_obj after the agreement data is retrieved.
* Bug 630091 - (cov#15582) Free of uninitialized pointer in attr_index_config()Nathan Kinder2010-09-131-1/+1
| | | | | | In attr_index_config(), if argc or argv are NULL, we jump to the done label. We then try to free attrs, but it was never initialized. We need to initialize attrs to NULL.
* Bug 630091 - (cov#15519) Initialize bervals in search_easter_egg()Nathan Kinder2010-09-131-2/+2
| | | | | In search_easter_egg(), we need to initialize the bervals before we pass them to slapi_ldif_parse_line().
* Bug 630091 - (cov#15516,15517) Initialize pointers before attempting to freeNathan Kinder2010-09-131-1/+2
| | | | | | | | If we encounter an error early in ldbm_instance_index_config_modify_callback(), we jump to the out label where we try to free origMatchingRules, but it may not be initialized. The same is true for origIndexTypes. We need to initialize these pointers to NULL.
* Bug 630091 - (cov#15515) Use of uninitialized array in index config codeNathan Kinder2010-09-131-1/+1
| | | | | | | | If we encounter an error early in ldbm_instance_index_config_modify_callback(), we jump to the out label where we free each element of the arglist array. This can happen without initializing the array. We need to initialize arglist before there is any chance to jump to the out label.
* Bug 630091 - (cov#15514) Initialize DBT in entryrdn_get_parent()Nathan Kinder2010-09-131-1/+3
| | | | | | | | In entryrdn_get_parent(), there is a DBT structure that we can use without initializing. If we goto the bail label, we try to free data.data, but data was never initialized. We should clear the memory used by data in the beginning of the function before we have an opportunity to goto bail.
* Bug 630091 - (cov#15513) Fix usage of uninitialized bervalsNathan Kinder2010-09-131-1/+2
| | | | | | We use some uninitialized bervals when the backend code calls slapi_ldif_parse_line(). We should be initializing the bervals to be empty.
* Bug 630091 - (cov#15512) Fix usage of uninitialized bervalsNathan Kinder2010-09-101-2/+2
| | | | | | When the server is built against MozLDAP, we use some uninitialized bervals when the backend code calls slapi_ldif_parse_line(). We should be initializing the bervals to be empty.
* Bug 690090 - (cov#11974) Remove additional unused ACL functionsNathan Kinder2010-09-091-131/+0
| | | | | | There are a few more unused ACL functions to remove. One of these unused functions is causing coverity to report an error about memory corruption.
* Bug 630094 - (cov#15581) Add missing breaks in agt_mopen_stats()Nathan Kinder2010-09-091-1/+4
| | | | | | | | | | | The switch statements in agt_mopen_stats() are missing breaks to prevent falling through to the next case when the stats file is opened in read-only mode. This looks like it causes the stats file to get opened a second time in read/write mode when ldap-agent attempts to open it in read-only mode. This may leak file descriptors in ldap-agent. We need to add the proper break statements.
* Bug 630094 - (cov#15520) Fix unreachable code issue if perfctrs codeNathan Kinder2010-09-091-3/+4
| | | | | | | | | | | | | The final frees of priv->memory and priv will never be reached since the function returns prior to these calls. It looks as if an "error:" label was removed at some point, as the WIN32 code in this function has goto statements using that label, but the label is not defined. The fix is to add the "error:" label in ifdef blocks for WIN32 that calls the free of priv. The free of priv->memory is not necessary since WIN32 doesn't use it and non-WIN32 builds don't use the error label at all.
* Bug 630094 - (cov#15459) Remove NULL check for srdn in ldif2ldbm codeNathan Kinder2010-09-091-1/+1
| | | | | | | | | | | In the call to slapi_log_error(), we are guaranteed that srdn is NULL if we are checking it for NULL due to the way the conditions are nested. The only time we check if srdn is NULL is if be is non-NULL, and the if condition guarantees that either be or srdn are NULL. We can just use the string "srdn" in our log message if be is non-NULL.
* Bug 630094 - (cov#15458) Fix deadcode issue in moddn codeNathan Kinder2010-09-091-1/+1
| | | | | | | | | | | In the moddn code that renames child entries, the for loop used to rename the children can never be executed. Part of the condition is that retval is 0, but retval will always be -1 the first time we hit this loop. This only happens with subtree rename off, but it should still be fixed. The fix is to set retval to 0 at the prior to checking the condition the first time.
* Bug 630094 - (cov#15457) Remove deadcode in import codeNathan Kinder2010-09-091-4/+0
| | | | | | | | The skipit variable is set to zero shortly before we check if it is 0 in an if condition. This if block can be removed since it will never be hit. The entry that was being freed in the if block is already removed earlier in the function if skipit was non-0 prior to resetting skipit to 0.
* Bug 630094 - (cov#15456) Remove NULL check for srdn in import codeNathan Kinder2010-09-091-1/+1
| | | | | | | | | | | In the call to slapi_log_error(), we are guaranteed that srdn is NULL if we are checking it for NULL due to the way the conditions are nested. The only time we check if srdn is NULL is if inst is non-NULL, and the if condition guarantees that either inst or srdn are NULL. We can just use the string "srdn" in our log message if inst is non-NULL.
* Bug 630094 - (cov#15455) Remove deadcode in attr_index_config()Nathan Kinder2010-09-091-128/+128
| | | | | | | | | If the index types (argv[1]) are not specified, attr_index_config() bails. We can remove some dead code where we check if "argc == 1" later in the function since that case can never happen. Additionally, we need to check if argc is 0, or if argv is NULL before attempting to parse the list of attributes to be indexed.
* Bug 630094 - (cov#15454) Fix deadcode issue in mapping tree codeNathan Kinder2010-09-091-1/+2
| | | | | | | | | | There is no chance for next_node to be anything other than NULL in the final return statement due to the return in the "if (next_node)" block immediately before the final return. We can remove the return inside of the "if (next_node)" block since the final return statement already deals with returning the proper value if next_node is non-NULL.
* Bug 630094 - (cov#15453) Eliminate NULL check for local_newentryNathan Kinder2010-09-091-1/+1
| | | | | | | | There is no chance for local_newentry to be anything other than NULL when we check it in the call to slapi_log_error() since the check only happens after we're verified that newparent and local_origsdn are not NULL. Since we are guaranteed that local_newentry is NULL, we can just eliminate this check and use the string "local entry" in the message that we print.
* Bug 630094 - (cov#15452) Remove NULL checking for op_stringNathan Kinder2010-09-091-26/+27
| | | | | | | | | | | There is no chance for op_string to be NULL if "rc == LDAP_SUCCESS" since op_string is set for all operation types in the switch statement, which is the only place that rc can be set to something other that the value of -1 that it is initialized to. We can just skip the NULL checking for op_string in the calls to slapi_log_error(). I also fixed the indentation to help me read the code easier.
* Bug 630094 - (cov#15451) Get rid of unreachable free statementsNathan Kinder2010-09-091-9/+0
| | | | | | | | | We need to remove the last "if (dnParts)" condition since it will never be true. The last frees of newDN, sval, and newvalue are also unnecessary since they are only set in the non subtree rename case, where they are already freed as well.
* Bug 630094 - (cov#11818) Fix unreachable return in snmp subagentNathan Kinder2010-09-091-17/+33
| | | | | | | | | | | | The return statement at the end of agt_mopen_stats() is unreachable according to coverity. This return was removed before to fix the coverity defect, but it was added back to fix a compiler warning. We can satisfy both the compiler and coverity by adding a rc variable to hold the return code. We can then return rc at the end of the function. This also allows us to clean up all of the return calls in this function by having all of them set rc and jump to a label at the function end.
* Bug 630090 - (cov#15445) Fix illegal free in archive codeNathan Kinder2010-09-091-1/+2
| | | | | | | | | | | The directory variable points to a dynamically allocated string returned by rel2abspath(). We are changing directory to point to a string constant if we are unable to parse the directory. This not only leaks memory, but it can cause us to attempt to free the string constant. We should free the string before we overwrite it, and we should dynamically allocate a new string instead of using a string constant.
* Bug 630090 - (cov#11974) Remove unused ACL functionsNathan Kinder2010-09-094-657/+3
| | | | | | | | | | | | | Coverity flagged a memory corruption issue in an old unused ACL function. It is best to just remove these unused functions. The functions removed are: ACL_ParseFile ACL_WriteFile ACL_WriteString ACL_Decompose acl_to_str_* acl_decompose_*
* Bug 630096 - (cov#15447) - Check return value of idl_append_extend()Nathan Kinder2010-09-081-2/+13
| | | | | | | | | | | We should check the return type of idl_append_extend(), though it does not seem possible that the return type will be anything other than 0. The only time idl_append_extend() returns anything other than 0 is when it is unable to allocate memory. Since the underlying allocation function is slapi_ch_calloc(), the server will just exit if it runs out of memory, which means we will never return up through idl_append_extend(). The right thing to do from a code standpoint is to still check for the return value though.
* Bug 630096 - (cov#15448) Check return value of cache_replace()Nathan Kinder2010-09-081-1/+6
| | | | | | | | | | | We need to check the return value of cache_replace() in id2entry_add_ext(). The only possible error that can be returned is when the entry we are trying to replace is not found in the cache. This should not occur since we are told that the entry already exists by CACHE_ADD() just prior to this call. If we run into this situation, we will just log an error without adding the entry to the cache. This shouldn't be a big deal since the entry will get added to the cache next time it is accessed.
* Bug 630096 - (cov#15449,15450) Check return value of stat()Nathan Kinder2010-09-082-4/+8
| | | | | | We were not checking the return value of stat() before attempting to access the structure that stat fille in in the protect_db code. This patch checks the return value first.
* Bug 630096 - (cov#15446) check return value of ber_scanf()Nathan Kinder2010-09-081-1/+4
| | | | | | | We were not checking the return value of ber_scanf in the DNA plug-in when parsing the range transfer response. This checks the return value and sets the return code to LDAP_PROTOCOL_ERROR if we were unable to parse the range transfer response.
* Bug 630096 - (cov#11778) check return value of ldap_parse_resultNathan Kinder2010-09-081-2/+15
| | | | | | | | | We were not checking the return value of ldap_parse_result in the windows_check_user_password() function. The old code was a bit unclear about setting rc when we encountered errors from ldap_result(). It also was calling ldap_parse_result() even if ldap_result() encountered an error. I fixed this code to be a bit more straightforward.
* Bug 630093 - (cov#15518) Need to intialize fd in ldbm2ldif codeNathan Kinder2010-09-081-4/+3
| | | | | | | | | | | Currently, the ldbm_back_ldbm2ldif() function could bail due to an error before fd is set. We then attempt to close the file that fd refers to. We should initialize fd to STDOUT_FILENUM, as we skip calling close() if fd is set to STDOUT_FILENUM. Additionally, I noticed that we could call close() when fd is negative or if it is STDERR or STDIN. I fixed this so close() is not called in those cases.
* Bug 630093 - (cov#15511) Don't use unintialized search_results in refint pluginNathan Kinder2010-09-081-64/+63
| | | | | | | | | | | The refint plug-in code currently looks as if it could use the search_result variable when it is uninitialized. I don't believe that this is possible since it would require the filter variable to be NULL, which should not occur since slapi_ch_smprintf() would make the process exit if it failed to allocate memory. Even so, the correct thing to do from a code cleanliness standpoint is to move all code that assumes we performed a search into the "if (filter)" block.
* Have to explicitly set protocol version to 3Rich Megginson2010-09-031-0/+5
