2022-05-04Conf: Allowing keyword redefinitionMaria Matejka
Some tokens are both keywords and symbols. For now, we allow only specific keywords to be redefined; in future, more of the keywords may be added to this category. The redefinable keywords must be specified in any .Y file as follows: toksym: THE_KEYWORD ; See proto/bgp/config.Y for an example. Also dropped a lot of unused terminals.
2022-05-04Explicit definition structures of route attributesMaria Matejka
Changes in internal API: * Every route attribute must be defined as struct ea_class somewhere. * Registration of route attributes known at startup must be done by ea_register_init() from protocol build functions. * Every attribute has now its symbol registered in a global symbol table defined as SYM_ATTRIBUTE * All attribute ID's are dynamically allocated. * Attribute value custom formatting hook is defined in the ea_class. * Attribute names are the same for display and filters, always prefixed by protocol name. Also added some unit testing code for filters with route attributes.

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.

2022-02-08Alloc: 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.
2022-01-08IO: 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.

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.

2021-11-09Split 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.

2021-10-13Multipage 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)".
