2022-02-27Babel: Fix bug in iface reconfigurationOndrej Zajicek (work)
A recent change in Babel causes ifaces to disappear after reconfiguration. The patch fixes that. Thanks to Johannes Kimmel for an insightful bugreport.

2022-02-13NEWS: Fix formatting and add some notesOndrej Zajicek (work)
2022-02-09NEWS and version updateOndrej Zajicek (work)
2022-02-08Alloc: Use posix_memalign() instead of aligned_alloc()Ondrej Zajicek (work)
For compatibility with older systems use posix_memalign(). We can switch to aligned_alloc() when we commit to C11 for multithreading.
2022-02-08Netlink: Minor cleanupOndrej Zajicek (work)
2022-02-07Lib: Update alignment of slabsOndrej Zajicek (work)
Alignment of slabs should be at least sizeof(ptr) to avoid unaligned pointers in slab structures. Fixme: Use proper way to choose alignment for internal allocators.
2022-02-06Merge branch 'oz-trie-table'Ondrej Zajicek (work)
2022-02-06Trie: Fix trie formatOndrej Zajicek (work)
After switching to 16-way tries, trie format ignored unaligned / internal prefixes and only reported the primary prefix of a trie node. Fix trie format by showing internal prefixes based on the 'local' bitmask of a node. Also do basic (intra-node) reconstruction of prefix patterns by finding common subtrees in 'local' bitmask. In future, we could improve that by doing inter-node reconstruction, so prefixes entered as one pattern for a subtree (e.g. 192.168.0.0/18+) would be reported as such, like with aligned prefixes.
2022-02-06Nest: Implement locking of prefix tries during walksOndrej Zajicek (work)
The prune loop may may rebuild the prefix trie and therefore invalidate walk state for asynchronous walks (used in 'show route in' cmd). Fix it by adding locking that keeps the old trie in memory until current walks are done. In future this could be improved by rebuilding trie walk states (by lookup for last found prefix) after the prefix trie rebuild.
2022-02-06Nest: Implement prefix trie pruningOndrej Zajicek (work)
When rtable is pruned and network fib nodes are removed, we also need to prune prefix trie. Unfortunately, rebuilding prefix trie takes long time (got about 400 ms for 1M networks), so must not be atomic, we have to rebuild a new trie while current one is still active. That may require some considerable amount of temporary memory, so we do that only if we expect significant trie size reduction.
2022-02-06Trie: Add prefix counterOndrej Zajicek (work)
Add counter of prefixes stored in trie. Works only for 'restricted' tries composed of explicit prefixes (pxlen == l == h), like ones used in rtables.
2022-02-06Doc: Describe routing table optionsOndrej Zajicek (work)
2022-02-06BGP: Implement flowspec validation procedureOndrej Zajicek (work)
Implement flowspec validation procedure as described in RFC 8955 sec. 6 and RFC 9117. The Validation procedure enforces that only routers in the forwarding path for a network can originate flowspec rules for that network. The patch adds new mechanism for tracking inter-table dependencies, which is necessary as the flowspec validation depends on IP routes, and flowspec rules must be revalidated when best IP routes change. The validation procedure is disabled by default and requires that relevant IP table uses trie, as it uses interval queries for subnets.
2022-02-06Nest: Add routing table configuration blocksOndrej Zajicek (work)
Allow to specify sorted flag, trie fla, and min/max settle time. Also do not enable trie by default, it must be explicitly enabled.
2022-02-06Nest: Add convenience functions to check rtable net typeOndrej Zajicek (work)
2022-02-06Nest: Avoid unnecessary net_format() in 'show route' commandOndrej Zajicek (work)
When output of 'show route' command was generated, the net_format() was called for each network prematurely, even if the result was not needed. Fix the code to call net_format() only when needed. This makes queries that process many networks but show only few (e.g. 'show route where ..', or 'show route count') much faster (like 5x - 10x faster).
2022-02-06Nest: Add trie iteration code to 'show route'Ondrej Zajicek (work)
Add trie iteration code to rt_show_cont() CLI hook and use it to accelerate 'show route in <addr>' commands using interval queries.
2022-02-06Nest: Implement 'show route in <addr>' commandOndrej Zajicek (work)
Implement 'show route in <addr>' command, which shows all routes in networks that are subnets of given network. Currently limited to IP network types.
