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.
- 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.
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.
o Changed parameters of f_run. Changed rtein+rteout pair to rte pointer
passed by reference, added ea_list of temporary attrs again passed
by reference and finally added a pointer to memory pool for storing
temporary data (new ea_lists's, temporary rta's etc.).
o Re-ordered result codes, so that all accepts come before all rejects.
o Introduced FILTER_ACCEPT and FILTER_REJECT dummy values (will be
used in protocol configurations).
o Added filter_name() which returns name of a filter or ACCEPT/REJECT
for the dummies.
o Introduced struct filter which serves as an external reference
to filter. Using struct symbol for this is unwise since it doesn't
allow extra information attached to the filter and it also forces
all filters to be named.
o Implemented config rule 'filter' which matches either named filter
or an embedded unnamed filter (`{ <filter> }').
o Fixed totally bogus comment at the top of filter.h.
o Added a missing prototype for f_run() to filter.h.
