Also, allow setting of agEffect to doNotAdvertiseMatching 05a,28feb03,kc Fixed SPR#86505 - modified per new mibApi.h header file updates. Renamed MAPI_COMMIT_NVM and MAPI_GET_NVM mApiReqType_t request type to MAPI_COMMIT_FORCE and MAPI_GET_FORCE respectively. 04z,24feb03,kc Fixed SPR#86385 - modified all ospf_mApi_xxxRowCreate(), ospf_mApi_xxxRowAccess() and ospf_mApi_xxxHelperSet() to return proper SNMPv2 error code using OSPF_MIB_ERROR_SET() macro. 04y,21feb03,kc Fixed SPR#86346 - modified ospf_mApi_areaRowAccess() to accept sendAreaSummary(2) as the valid value for ospfAreaSummary object and to dynamically configured OSPF for changes to the ospfAreaSummary only if the area is configured as stub. 04x,21feb03,kc Fixed SPR#86134 - modified ospf_mApi_areaAggregateRowAccess() to return error for ospfAreaAggregateEffect object validation if set to the unsupported doNotAdvertiseMatching(2). 04w,18feb03,kc Fixed SPR#86135 - modified ospf_mApi_stubDelete() to reinitialize the OSPF Area using the default metric value when the stub entry is deleted from the ospfStubTable. 04v,07feb03,kc Fixed SPR#86144 - removed the mApiReqType_t argument from all the ospf_mApi_xxxHelperCreate() routines. These routine no longer attempt to reconfigure OSPF if the reqType type is not MAPI_COMMIT_NVM. Also removed the dynamicConfig argument from ospf_mApi_ifRowSet() and ospf_mApi_virtIfRowSet() routines. 04u,03feb03,kc Fixed SPR#85865 - modified ospf_mApi_configurationGet() to update the ABR status if necessary. 04t,01feb03,kc Fixed SPR#86017 - modified ospf_mApi_areaDelete to set the rowStatus for the attached interface to notReady regardless if the OSPF protocol is running. Also reset all the read-only operational status and stats objects if interface is successfully removed from OSPF. 04s,31jan03,kc Fixed SPR#86009 - modified ospf_mApi_ifRowCreate() to assign the actual value of the Area ID from mApiObject_t to the ospfIfAreaId columnar object during the MAPI_TEST phase. 04r,31jan03,kc Fixed SPR#86006 - modified all the ospf_mApi_xxxHelperSet() routines to invoke avlDelete() to remove the row created from the avl tree. 04q,12dec02,mwv Fix compiler warning 04p,19nov02,kc Modified ospf_mApi_ifHelperCreate() and ospf_mApi_ifConfigAccess() to explicitly invoke the ospf_mApi_ifInfoGet() when ospf is reinitialized. SPR 84478, 84485, 84486 04o,19nov02,mwv Merge TMS code SPR 84284 04n,12nov02,kc Fixed SPR#75884 - Added ospf_mApi_nbrHelperDeregister(). 04m,08oct02,agi Fixed compiler warnings 04l,15aug02,kc Modified ospf_mApi_virtIfRowStatusAccess() to place the return statement at the correct spot. 04k,09aug02,kc Modified ospf_mApi_ifRowCreate() to correctly validate the index value for unnumbered interface. 04j,17jun02,kc Modified ospf_mApi_xxxHelperSet() to handle possible pObjCookie not implemented, thus corrected possible NULL pointer access. 04i,25may02,kc Fixed PR #2700 - Added deleteFromOspf boolean flag function argument to ospf_mApi_ifDelete(). 04h,21may02,kc Fixed ospf_mApi_xxxHelperSet() to extract the object cookie data from the request message. Added the isLastColObject parameter to the rsRowStatusSet() function call. 04g,23apr02,kc Fixed ospf_mApi_areaRegisterIf() to correctly increment the active interface counter for MAPI_COMMIT_NVM request. 04f,18apr02,kc Don't trigger ospf_mApi_avlTreeWalk() for ospfNbrTable in ospf_mApi_reset(). The ospfNbrTable and ospfVirtNbrTable will be explicitly flushed by ospf2Mapi_shutdown(). 04e,16apr02,kc Modified authentication type and key set request in ospf_mApi_ifRowAccess() and ospf_mApi_virtIfRowAccess() to allow dynamic configuration only if both the authentication type and key have been defined. 04d,16apr02,kc Modified ospf_mApi_md5KeyIdValidate() to make sure md5 key id is indeed within 1 to 255 and to return the md5 key id. Modified ospf_mApi_ifHelperGet() and ospf_mApi_virtIfHelperGet() to return the actual authentication key if request is MAPI_GET_NVM. Modified ospf_mApi_md5AuthKeyParsing() to correctly track the md5 authentication key and key id length from the given buffer. 04c,15apr02,kc Renamed EmapiOspfAuthType_simplePasswd mApiOspfAuthType_t to EmApiOspfAuthType_simplePasswd. Renamed MAPI_NVM_SET to MAPI_COMMIT_NVM and pCookie pointer to pReqCookie pointer per mibApi.h update. 04b,13apr02,kc Fixed PR #2611 - corrected simple authentication key processing for ospfIfAuthKey and ospfVirtIfAuthKey. 04a,11apr02,kc Added ospf_mApi_ifHelperDelete() routine. Fixed ospf_mApi_ifDelete() to also check if interface row status is active and administrative status is enabled before deleting the interface from OSPF. 03z,10apr02,kc Moved AVL_WALK_FUNC to ospf_mib_helper.h. Made ospf_mApi_avlTreeWalk() public. Added splnet() call in ospf_mApi_ifInfoGet() to lock spl semaphore so to allow ifa_ifwithaddr() to have exclusive access to the system interface list. 03y,05apr02,kc Fixed ospf_mApi_xxxHelperSet() to delete the row if error occurs during validation phase. Corrected the area registration process for area aggregation. Fixed RS_ACCESS_COL_VALID for ospf_mApi_ifRowAccess() to return error if changing an interface area id breaks the virtual interface(s). 03x,04apr02,kc Modified ospf_mApi_walkxxxTree() to force the row status transition only if the request is not NVM_SET. Invoke ospf_mApi_areaConfig() in ospf_mApi_areaRowStatusAccess() when the row is first created. 03w,03apr02,kc Fixed ospf_mApi_areaAggregateRowCreate() to correctly lookup the area using the appropriate area id. Fixed ospf_mApi_areaStatusUpdate() to correctly decrement the numActiveArea counter when an area is deleted (or when the interface state has changed). 03v,02apr02,kc Modified ospf_mApi_ifInfoGet() to locate the interface based on the complete interface address. 03u,01apr02,kc Modified ospf_mApi_areaAggregateRowCreate() to look for the area to which the area aggregation instance is configured for prior memory is allocated for the instance. 03t,29mar02,kc Fixed up virtual link configuration. Only allow virtual link to go active if there is at least one active interface in the transit area. Fixed area configuration so that if
