2022-05-04Unified attribute and filter typesMaria Matejka
This commit removes the EAF_TYPE_* namespace completely and also for route attributes, filter-based types T_* are used. This simplifies fetching and setting route attributes from filters. Also, there is now union bval which serves as an universal value holder instead of private unions held separately by eattr and filter code.
2022-05-04Filter: Bitfield eattrs reading / writing moved to filter codeMaria Matejka
Before this change, fetch-update-write and bitmasking was hardcoded in attribute access code cased by the attribute type. Several filter instructions are used to do it instead. As this is certainly going to be a little bit slower than before, the switch block in attribute access code should be completely removed in near future, helping with both performance and code cleanliness. The user interface should have stayed intact.

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)
2022-01-17Netlink: Add option to specify netlink socket receive buffer sizeOndrej Zajicek (work)
Add option 'netlink rx buffer' to specify netlink socket receive buffer size. Uses SO_RCVBUFFORCE, so it can override rmem_max limit. Thanks to Trisha Biswas and Michal for the original patches.
2022-01-15Netlink: Add another workaround for older kernel headersOndrej Zajicek (work)
Unfortunately, SOL_NETLINK is both recently added and arch-dependent, so we cannot just define it.

2022-01-14Netlink: Enable strict checking for KRT dumpsOndrej Zajicek (work)
Add strict checking for netlink KRT dumps to avoid PMTU cache records from FNHE table dump along with KRT. Linux Kernel added FNHE table dump to the netlink API in patch: https://patchwork.ozlabs.org/project/netdev/patch/8d3b68cd37fb5fddc470904cdd6793fcf480c6c1.1561131177.git.sbrivio@redhat.com/ Therefore, since Linux 5.3 these route cache entries are dumped together with regular routes during periodic KRT scans, which in some cases may be huge amount of useless data. This can be avoided by using strict checking for netlink dumps: https://lore.kernel.org/netdev/20181008031644.15989-1-dsahern@kernel.org/ The patch mitigates the risk of receiving unknown and potentially large number of FNHE records that would block BIRD I/O in each sync. There is a known issue caused by the GRE tunnels on Linux that seems to be creating one FNHE record for each destination IP address that is routed through the tunnel, even when the PMTU equals to GRE interface MTU. Thanks to Tomas Hlavacek for the original patch.
2022-01-14Netlink: Explicitly skip received cloned routesOndrej Zajicek (work)
Kernel uses cloned routes to keep route cache entries, but reports them together with regular routes. They were skipped implicitly as they do not have rtm_protocol filled. Add explicit check for cloned flag and skip such routes explicitly. Also, improve debug logs of skipped routes.
2022-01-08IO: Support nonlocal bind in socket interfaceAlexander Zubkov
Add option to socket interface for nonlocal binding, i.e. binding to an IP address that is not present on interfaces. This behaviour is enabled when SKF_FREEBIND socket flag is set. For Linux systems, it is implemented by IP_FREEBIND socket flag. Minor changes done by commiter.
2022-01-05Netlink: Do not ignore dead routes from BIRDOndrej Zajicek (work)
Currently, BIRD ignores dead routes to consider them absent. But it also ignores its own routes and thus it can not correctly manage such routes in some cases. This patch makes an exception for routes with proto bird when ignoring dead routes, so they can be properly updated or removed. Thanks to Alexander Zubkov for the original patch.
2022-01-05Netlink: Improve multipath parsing errorsOndrej Zajicek (work)
Function nl_parse_multipath() should handle errors internally.
2021-12-27BSD: Assume onlink flag on ifaces with only host addressesOndrej Zajicek (work)
The BSD kernel does not support the onlink flag and BIRD does not use direct routes for next hop validation, instead depends on interface address ranges. We would like to handle PtMP cases with only host addresses configured, like: ifconfig wg0 192.168.0.10/32 route add 192.168.0.4 -iface wg0 route add 192.168.0.8 -iface wg0 To accept BIRD routes with onlink next-hop, like: route 192.168.42.0/24 via 192.168.0.4%wg0 onlink BIRD would dismiss the route when receiving from the kernel, as the next-hop 192.168.0.4 is not part of any interface subnet and onlink flag is not kept by the BSD kernel. The commit fixes this by assuming that for routes received from the kernel, any next-hop is onlink on ifaces with only host addresses. Thanks to Stefan Haller for the original patch.
2021-11-24Directly mapped pages are kept for future use if temporarily not neededMaria Matejka
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.

table structures directly
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.
