2011-09-25isisd: fix crash on "no router isis" (BZ#536)Fritz Reichmann
The crash is due to threads accessing data that gets destroyed during the removal of the configuration. * isis_circuit.c: Destroy adjacencies to stop adjacency expiry thread. Stop PSNP threads. * isisd.c: Change state of circuit back to INIT and reassign the circuit structure to isis->init_circ_list rather than destroying the circuit data structure. Stop SPF threads. Stop LSP generation threads. * isisd.h: Add pointers to LSP threads into area structure in order to stop them in isisd.c * isis_lsp.c: Store pointer to LSP thread in area structure. * isis_pdu.c: Stop PDU generation for a circuit with a removed area. * isis_pfpacket.c: Stop processing received PDUs for a circuit with a removed area.
2005-09-28 * isis_dynh.c, isisd.h: Implement dynamic hostname cache cleanup.hasso
* isis_lsp.c: Refresh dynamic hostname in the cache while refreshing topology LSP.
2005-09-26 * isis_spf.c: Changing cost from uint16_t to uint32_t. Unsethasso
ISIS_ROUTE_FLAG_ACTIVE flag before running SPF. * isisd.[ch]: Separate route tables for different levels. SPF is done separately, but in case of L1L2 area they have to be merged. * isis_zebra.c: Set/unset ISIS_ROUTE_FLAG_ZEBRA_SYNC flag correctly in case of adding/removing IPv4 routes. * zebra_route.c: Rework route validating process. Merging L1 and L2 tables in case of L1L2 area. In short - many changes to make SPF work more correctly, add/remove to/from RIB also works now. It's still very far from perfect though.
2005-09-26 * isisd.[ch]: Introduce oldmetric flag for area and transitionhasso
metricstyle command. With metricstyle wide only extended TLVs should be used.
2005-09-19 * isis_lsp.h: Added backpointer to the area from LSP. For now it's usedhasso
only in generated topology LSPs. * isisd.[ch]: Cleanup CLI commands related to topology generation and added command to specify base fo dynamic hostname for topology LSPs. * isis_lsp.c: Rewrite almost all code related to generation topology LSPs (top_lsp_refresh(), generate_topology_lsps() and build_topology_lsp_data() functions). Topology is connected to own LSP now (lsp_build_nonpseudo). Commented out lsppdu_realloc functions, it's not used any more hopefully. Topology generation feature is actually useful now.
2005-09-04 * *.c: Try to be less verbose by default (without any debug optionshasso
on). * isis_lsp.c (lsp_build_nonpseudo): Use stream_reset() instead of touching endp directly. * isis_lsp.c (lsp_build_pseudo): Ditto.
2005-04-02 * configure.ac: Add --enable-isis-topology to enable isisd topologyhasso
generator code. * isisd/Makefile.am: Variables to handle conditonal compiling of topology generator code. * isisd/isis_lsp.c: lsppdu_realloc() is used by topology generator. * isisd/isisd.c: Rename show_isis_topology_cmd to not conflict the one in the isis_spf.c. * isisd/isisd.h: Remove TOPOLOGY_GENERATE define, it will be defined in toplevel config.h if topology generator is enabled. * isisd/topology/Makefile.am: Handle the libtoolized Quagga libraries.
2004-10-11Sync isisd with changes in lib.hasso
2004-09-10Indentation only. No any functional changes.hasso
2003-12-23Merge isisd into the Quagga's framework:jardin
- add privs support - use misc quagga's definitions - make it compile"able" - fix segfault cases related to hostname() - add debug isis xxx command This patch has been approved by Paul Jakma.
