Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.
Fixed make doc on recent Debian together with moving generated doc into
objdir.
Moved Makefile.in into root dir
Retired all.o and birdlib.a
Linking the final binaries directly from all the .o files.
The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.
The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.
Router ID could be automatically determined based of subset of
ifaces/addresses specified by 'router id from' option. The patch also
does some minor changes related to router ID reconfiguration.
Thanks to Alexander V. Chernikov for most of the work.
Several new configure command variants:
configure undo - undo last reconfiguration
configure timeout - configure with scheduled undo if not confirmed in timeout
configure confirm - confirm last configuration
configure check - just parse and validate config file
- 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.
Filter code used 'aux' integer field of 'symbol' struct to store ptr
to next symbol and both 'aux2' and 'def' fields for value.
Changed to just 'def' for value and 'aux2' for ptr to next symbol.
Also another minor bugfix.
Pavel's fault that he's never tested shadowing of declarations in the filters.
cf_define_symbol() has been modified to check the scope of the symbol it's
given and it if it's an already defined symbol, but in a different scope,
a copy is created in the current scope and redefined to the new meaning,
the consequence being that it cf_define_symbol() now returns the new symbol
you need to use when assigning aux and aux2.
o Use `expr' instead of `NUM' and `ipa' instead of `IPA',
so that defined symbols work everywhere.
o `define' now accepts both numbers and IP addresses.
o Renamed `ipa' in filters to `fipa'.
Pavel, please update filters to accept define'd symbols as well.
used for automatic generation of instance names.
protocol->name is the official name
protocol->template is the name template (usually "name%d"),
should be all lowercase.
Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.
we want to allow filter and similar complex constructs to be used in commands
and we should avoid code duplication), only with CLI_MARKER token prepended
before the whole input.
Defined macro CF_CLI(cmd, args, help) for defining CLI commands in .Y files.
The first argument specifies the command itself, the remaining two arguments
are copied to the help file (er, will be copied after the help file starts
to exist). This macro automatically creates a skeleton rule for the command,
you only need to append arguments as in:
CF_CLI(STEAL MONEY, <$>, [[Steal <$> US dollars or equivalent in any other currency]]): NUM {
cli_msg(0, "%d$ stolen", $3);
} ;
Also don't forget to reset lexer state between inputs.
o cf_define_symbol() -- it assigns a meaning to a symbol, bailing
out if it already has one.
o cf_find_symbol() -- finds symbol by name and creates it if not found.
Also modified filter/config.Y to make use of the first function.
