The two-letter instructions were quite messy but they could be easily
read from memory dumps. Now GDB (since 2012) supports pretty printing
enum values and GCC checks the switch construction for missing enum
values so we are converting the nice two-byte values to enums.
Anyway, the enum still keeps the old two-byte values to be able to read
the instruction codes even without GDB from plain memory dump.
A filter should log messages only if executed explicitly (e.g., during
route export or route import). When a filter is executed for technical
reasons (e.g., to establish whether a route was exported before), it
should run silently.
The patch implements Default Router Preferences and More-Specific Routes
(RFC 4191) for RAdv protocol, allowing to announce router preference and
more specific routes in router advertisements. Routes can be exported to
RAdv like to regular routing protocols.
Some cleanups, bugfixes and other changes done by Ondrej Zajicek.
Add support for large communities (draft-ietf-idr-large-community),
96bit alternative to RFC 1997 communities.
Thanks to Matt Griswold for the original patch.
The patch adds suport for specifying route attributes together with
static routes, e.g.:
route 10.1.1.0/24 via 10.0.0.1 { krt_advmss = 1200; ospf_metric1 = 100; };
Implemented eval command can be used to evaluate expressions.
The patch also documents echo command and allows to use log classes
instead of integer as a mask for echo.
- ROA tables, which are used as a basic part for RPKI.
- Commands for examining and modifying ROA tables.
- Filter operators based on ROA tables consistent with RFC 6483.
Changes the time complexity of the algorithm from O(n^2) to O(n*log(n)).
This speeds up loading of huge DEC-IX config from 128 s to 15 s. It also
makes the code significantly simpler.
Prefix sets were broken beyond any repair and have to be reimplemented.
They are reimplemented using a trie with bitmasks in nodes.
There is also change in the interpretation of minus prefix pattern,
but the old interpretation was already inconsistent with
the documentation and broken.
There is also some bugfixes in filter code related to set variables.
of filter/config.Y. Bird now compiles even if you disable RIP.
Removed RTA and IMPOSSIBLE tokens (unused).
Removed superfluous comment in filter.h.
I've tried to do my best, but Pavel, please check these changes.
