2021-11-22Table import and export are now explicit hooks.Maria Matejka
Channels have now included rt_import_req and rt_export_req to hook into the table instead of just one list node. This will (in future) allow for: * channel import and export bound to different tables * more efficient pipe code (dropping most of the channel code) * conversion of 'show route' to a special kind of export * temporary static routes from CLI The import / export states are also updated to the new algorithms.
2021-11-19Trie: Implement trie walking codeOndrej Zajicek (work)
Trie walking allows enumeration of prefixes in a trie in the usual lexicographic order. Optionally, trie enumeration can be restricted to a chosen subnet (and its descendants).
2021-11-13Trie: Simplify network matching codeOndrej Zajicek (work)
Introduce ipX_prefix_equal() and use it to simplify network matching code.

table structures directly
2021-11-09Route export: rejected by filter bitmapMaria Matejka
If a route has been rejected by filter, store that information to avoid repeated export filter runs on rejected routes.

2021-11-09Split route data structure to storage (ro) / manipulation (rw) structures.Maria Matejka
Routes are now allocated only when they are just to be inserted to the table. Updating a route needs a locally allocated route structure. Ownership of the attributes is also now not transfered from protocols to tables and vice versa but just borrowed which should be easier to handle in a multithreaded environment.

2021-10-20Conf: Fix crash during shutdownOndrej Zajicek (work)
BIRD implements shutdown by reconfiguring to fake empty configuration. Such fake config structure is created from the last running config and shares some data, including symbol table. This allows access to (removed) routing tables and causes crash when 'show route' command is used during shutdown. Clean up symbol table, table list and links to default tables, so removed routing tables cannot be accessed during shutdown.

2021-10-13Route: moved rte_src pointer from rta to rteMaria Matejka
It is an auxiliary key in the routing table, not a route attribute.

2021-10-13RIP fixup + dropping the tmp_attrs mechanism as obsoleteMaria Matejka
2021-10-13Dropping the RTS_DUMMY temporary route storage.Maria Matejka
Kernel route sync is done by other ways now and this code is not used currently.
2021-10-13Preference moved to RTA and set explicitly in protocolsMaria Matejka
2021-10-13Export table: Delay freeing of old stored route.Maria Matejka
This is needed to provide the protocols the full old route after filters when export table is enabled.

2021-10-13IGP metric getter refactoring to protocol callbackMaria Matejka
Direct protocol hooks for IGP metric inside nest/rt-table.c make the protocol API unnecessarily complex. Instead, we use a proper callback.
2021-10-13fixup! Multipage allocationMaria Matejka
2021-10-13Multipage allocationMaria Matejka
We can also quite simply allocate bigger blocks. Anyway, we need these blocks to be aligned to their size which needs one mmap() two times bigger and then two munmap()s returning the unaligned parts. The user can specify -B <N> on startup when <N> is the exponent of 2, setting the block size to 2^N. On most systems, N is 12, anyway if you know that your configuration is going to eat gigabytes of RAM, you are almost forced to raise your block size as you may easily get into memory fragmentation issues or you have to raise your maximum mapping count, e.g. "sysctl vm.max_map_count=(number)".

2021-09-25Filter: Add prefix trie benchmarksOndrej Zajicek (work)
Add trie tests intended as benchmarks that use external datasets instead of generated prefixes. As datasets are not included, they are commented out by default.
2021-09-25Filter: Improve prefix trie testsOndrej Zajicek (work)
Add tests explicitly matching insides and outsides of trie and update tests to do testing of both IPv4 and IPv6 tries.
