069bfcb53c Fixes serious bug in core related to route filtering. 
If protocol announces a route, route is accepted by import filter to
routing table, and later it announces replacement of that route that is
rejected by import filter, old route remains in routing table.

20e94fb85b A change in OSPF and RIP interface patterns. 
Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:

interface "eth3" { options ... }, "eth4" { options ... };

c8a6b9a3d1 Rewrite of buggy AS path matching. 
Old AS path maching supposes thath AS number appears
only once in AS path, but that is not true. It also
contains some bugs related to AS path sets.

New code does not use any assumptions about semantic
structure of AS path. It is asymptotically slower than
the old code, but on real paths it is not significant.

It also allows '?' for matching one arbitrary AS number.

024c310b53 Fixes broken cryptographic authentication in OSPF 
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.

That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

48d79d521c Better handling of AS4 optional attribute errors 
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
 - ignoring invalid AS4 optional attributes.

b807ef9a15 Fixes bug in protocol state machine 
Scheduling flush must be done before resource pool freeing as it
frees some allocated list nodes from a global list.
 2009-02-12 13:43:06 +01:00
Ondrej Zajicek
d6a836f8d6 Fixes core state machine. 
The core state machine was broken - it didn't free resources
in START -> DOWN transition and might freed resources after
UP -> STOP transition before protocol turned down. It leads
to deadlock on olock acquisition when lock was not freed
during previous stop.

The current behavior is that resources, allocated during
DOWN -> * transition, are freed in * -> DOWN transition,
and flushing (scheduled in UP -> *) just counteract
feeding (scheduled in * -> UP). Protocol fell down
when both flushing is done (if needed) and protocol
reports DOWN.

BTW, is thera a reason why neighbour cache item acquired
by protocol is not tracked by resource mechanism?

Ondrej Zajicek
fbde6c3908 Fixes race condition leading to memory corruption and crash. 
When protocol started, feeding was scheduled. If protocol
got down before feeding was executed, then function
responsible for connecting protocol to kernel routing
tables was called after the function responsible for
disconnecting, then resource pool of protocol was freed,
but freed linked list structures remains in the list.

b21f68b4cd Fix bugs in OSPF MD5 authentication. First bug is that default 
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.

It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

13b75bacf7 protocol->import_control() could potentially call rte_cow() as well.

 2003-08-13 20:04:39 +00:00
Martin Mares
2adab6ae9c This was a potential memory leak, but not the one Feela observed. 
This one could happen when an import filter of some protocol modified
the rte (so that it would be rte_cow()ed) and later rejected it.

e3f2d5fce3 Cleanup of configuration. 
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.

Pavel, please update filters to accept define'd symbols as well.

08f0290a1e Changed semantics of the rt_update hook. The attribute list we pass now 
contains all attributes, not just the temporary ones. This avoids having
to merge the lists inside protocols or doing searches on both of them.

Also, do filtering of routes properly. (I'd like to avoid it, but it's
needed at least in the krt protocol.)

Martin Mares
ce1da96ee7 Added commands show route protocol <p>' and show route import <p>' which 
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an
attribute list and all protocol specific rte attributes are contained
there as temporary ones. Updated RIP to do that.

Added ea_append() which joins two ea_list's.

Martin Mares
3991d84e8f Changed initialization of protocol list -- now we call proto_build() instead 
of calling the protocols manually.

Implemented printing of dynamic attributes in `show route all'.

Each protocol can now register its own attribute class (protocol->attr_class,
set to EAP_xxx) and also a callback for naming and formatting of attributes.
The callback can return one of the following results:

	GA_UNKNOWN	Attribute not recognized.
	GA_NAME		Attribute name recognized and put to the buffer,
			generic code should format the value.
	GA_FULL		Both attribute name and value put to the buffer.

Please update protocols generating dynamic attributes to provide
the attr_class and formatting hook.

Martin Mares
96d8e3bff2 Added protocol debugging flags (protocol.h: D_xxx), parsing of them 
in configuration files and commands for manipulating them.

Current debug message policy:

   o  D_STATES, D_ROUTES and D_FILTERS are handled in generic code.
   o  Other debug flags should be handled in the protocols and whenever
      the flag is set, the corresponding messages should be printed
      using calls to log(L_TRACE, ...), each message prefixed with
      the name of the protocol instance. These messages should cover
      the whole normal operation of the protocol and should be useful
      for an administrator trying to understand what does the protocol
      behave on his network or who is attempting to diagnose network
      problems. If your messages don't fit to the categories I've defined,
      feel free to add your own ones (by adding them to protocol.h
      and on two places in nest/config.Y), but please try to keep the
      categories as general as possible (i.e., not tied to your protocol).
   o  Internal debug messages not interesting even to an experienced
      user should be printed by calling DBG() which is either void or
      a call to debug() depending on setting of the LOCAL_DEBUG symbol
      at the top of your source.
   o  Dump functions (proto->dump etc.) should call debug() to print
      their messages.
   o  If you are doing any internal consistency checks, use ASSERT
      or bug().
   o  Nobody shall ever call printf() or any other stdio functions.

Also please try to log any protocol errors you encounter and tag them
with the appropriate message category (usually L_REMOTE or L_AUTH). Always
carefully check contents of any message field you receive and verify all
IP addresses you work with (by calling ipa_classify() or by using the
neighbour cache if you want to check direct connectedness as well).

6a636392d3 Rewrote interface type detection logic. The `unnumbered' flag is now per

wise to rely on it on interfaces configured with /30 prefix.

d272fe22dd Separated `official protocol names' used in status dumps from name templates 
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.

Martin Mares
f545d38707 Added universal locking mechanism which will solve problems 
with protocols wanting to use the same port on the same interface
during reconfiguration time.

How to use locks: In the if_notify hook, just order locks for the
interfaces you want to work with and do the real socket opening after the
lock hook function gets called. When you stop using the socket, close
it and rfree() the lock.

Please update your protocols to use the new locking mechanism.
