2022-09-21Caching eattrs in filters is not needed anymore.Maria Matejka
After flattening the route attribute structure, the ea_list ** is derivable from rte * by arithmetics. Caching the derived value doesn't help performance and therefore is removed as unnecessary.

2022-06-27Filter: Implement for loopsOndrej Zajicek (work)
For loops allow to iterate over elements in compound data like BGP paths or community lists. The syntax is: for [ <type> ] <variable> in <expr> do <command-body>
2022-06-27Filter: Implement mixed declarations of local variablesOndrej Zajicek (work)
Allow variable declarations mixed with code, also in nested blocks with proper scoping, and with variable initializers. E.g: function fn(int a) { int b; int c = 10; if a > 20 then { b = 30; int d = c * 2; print a, b, c, d; } string s = "Hello"; }
2022-06-27Filter: Improve handling of stack frames in filter bytecodeOndrej Zajicek (work)
When f_line is done, we have to pop the stack frame. The old code just removed nominal number of args/vars. Change it to use stored ventry value modified by number of returned values. This allows to allocate variables on a stack frame during execution of f_lines instead of just at start. But we need to know the number of returned values for a f_line. It is 1 for term, 0 for cmd. Store that to f_line during linearization.
2022-06-27Filter: Simplify handling of command sequencesOndrej Zajicek (work)
Command sequences in curly braces used a separate nonterminal in grammar. Handle them as a regular command.
2022-06-27Filter: Fix bug in variable shadowingOndrej Zajicek (work)
When a new variable used the same name as an existing symbol in an outer scope, then offset number was defined based on a scope of the existing symbol ($3) instead of a scope of the new symbol (sym_). That can lead to two variables sharing the same memory slot.
2022-06-27Filter: Implement direct recursionOndrej Zajicek (work)
Direct recursion almost worked, just crashed on function signature check. Split function parsing such that function signature is saved before function body is processed. Recursive calls are marked so they can be avoided during f_same() and similar code walking. Also, include tower of hanoi solver as a test case.
2022-06-27Filter: Apply constant promotion for FI_EQ / FI_NEQOndrej Zajicek (work)
Equality comparison is defined on all values, even of different types, but we still want to do constant promotion if possible.
2022-06-27Filter: Add literal for empty setAlexander Zubkov
Add literal for empty set [], which works both for tree-based sets and prefix sets by using existing constant promotion mechanism. Minor changes by committer.
2022-06-27Nest: Cleanups in as_path_filter()Ondrej Zajicek (work)
Use struct f_val as a common argument for as_path_filter(), as suggested by Alexander Zubkov. That allows to use NULL sets as valid arguments.
2022-06-27Filter: Ensure that all expressions declared return typeOndrej Zajicek (work)
All instructions with a return value (i.e. expressions, ones with non-zero outval, third argument in INST()) should declare their return type. Check that automatically by M4 macros. Set outval of FI_RETURN to 0. The instruction adds one value to stack, but syntactically it is a statement, not an expression. Add fake return type declaration to FI_CALL, otherwise the automatic check would fail builds.
2022-06-27Filter: Improve description of type systemOndrej Zajicek (work)
2022-06-27Filter: Implement type checks for function callsOndrej Zajicek (work)
Keep list of function parameters in f_line and use it to verify types of arguments for function calls. Only static type checks are implemented.
2022-06-27Filter: Clean up function call instructionOndrej Zajicek (work)
Pass instructions of function call arguments as vararg arguments to FI_CALL instruction constructor and move necessary magic from parser code to interpreter / instruction code.

There were quite a lot of conflicts in flowspec validation code which ultimately led to some code being a bit rewritten, not only adapted from this or that branch, yet it is still in a limit of a merge.

2022-05-30Squashing the route attribute structure into one level.Maria Matejka
For now, all route attributes are stored as eattrs in ea_list. This should make route manipulation easier and it also allows for a layered approach of route attributes where updates from filters will be stored as an overlay over the previous version.
2022-05-30Route destination field merged with nexthop attribute; splitting flowspec ↵Maria Matejka
validation result out. As there is either a nexthop or another destination specification (or othing in case of ROAs and Flowspec), it may be merged together. This code is somehow quirky and should be replaced in future by better implementation of nexthop. Also flowspec validation result has its own attribute now as it doesn't have anything to do with route nexthop.
2022-05-26Moved nexthop from struct rta to extended attribute.Maria Matejka
This doesn't do anything more than to put the whole structure inside adata. The overall performance is certainly going downhill; we'll optimize this later. Anyway, this is one of the latest items inside rta and in several commits we may drop rta completely and move to eattrs-only routes.
2022-05-04Moved route source attribute (RTS_*) to eattrsMaria Matejka
2022-05-04Removing the route scope attribute. Use custom attributes instead.Maria Matejka
The route scope attribute was used for simple user route marking. As there is a better tool for this (custom attributes), the old and limited way can be dropped.
2022-05-04Moved route preference to eattrsMaria Matejka
