2019-09-15lib: rmap dep table is not correct in case of exact-match clausevdhingra
User pass the string match large-community 1 exact-match from CLI. Now route map lib has got the string as "1 exact-match". It passes the string to call back for compilation. BGP will parse this string and came to know that for "1" it has to do exact match. Routemap lib has to save "1" in it’s dependency table. Here routemap is saving this as a “1 exact-match” which is wrong. The solution is used the compiled data. Signed-off-by: vishaldhingra <vdhingra@vmware.com>

2019-07-22lib: Introducing a 3rd state for route-map match cmd: RMAP_NOOPLakshman Krishnamoorthy
Introducing a 3rd state for route_map_apply library function: RMAP_NOOP Traditionally route map MATCH rule apis were designed to return a binary response, consisting of either RMAP_MATCH or RMAP_NOMATCH. (Route-map SET rule apis return RMAP_OKAY or RMAP_ERROR). Depending on this response, the following statemachine decided the course of action: State1: If match cmd returns RMAP_MATCH then, keep existing behaviour. If routemap type is PERMIT, execute set cmds or call cmds if applicable, otherwise PERMIT! Else If routemap type is DENY, we DENYMATCH right away State2: If match cmd returns RMAP_NOMATCH, continue on to next route-map. If there are no other rules or if all the rules return RMAP_NOMATCH, return DENYMATCH We require a 3rd state because of the following situation: The issue - what if, the rule api needs to abort or ignore a rule?: "match evpn vni xx" route-map filter can be applied to incoming routes regardless of whether the tunnel type is vxlan or mpls. This rule should be N/A for mpls based evpn route, but applicable to only vxlan based evpn route. Also, this rule should be applicable for routes with VNI label only, and not for routes without labels. For example, type 3 and type 4 EVPN routes do not have labels, so, this match cmd should let them through. Today, the filter produces either a match or nomatch response regardless of whether it is mpls/vxlan, resulting in either permitting or denying the route.. So an mpls evpn route may get filtered out incorrectly. Eg: "route-map RM1 permit 10 ; match evpn vni 20" or "route-map RM2 deny 20 ; match vni 20" With the introduction of the 3rd state, we can abort this rule check safely. How? The rules api can now return RMAP_NOOP to indicate that it encountered an invalid check, and needs to abort just that rule, but continue with other rules. As a result we have a 3rd state: State3: If match cmd returned RMAP_NOOP Then, proceed to other route-map, otherwise if there are no more rules or if all the rules return RMAP_NOOP, then, return RMAP_PERMITMATCH.

Say, more than one sequence of a route-map uses the same named entity in its match clause. After that entity is removed from any one of the route-map sequences, any further changes made to that entity doesn't dynamically take effect. A reference counter, that allows the named entity to keep a count of the route-maps dependent on it, has been introduced to address this issue.

Introducing a 3rd state for route_map_apply library function: RMAP_NOOP Traditionally route map MATCH rule apis were designed to return a binary response, consisting of either RMAP_MATCH or RMAP_NOMATCH. (Route-map SET rule apis return RMAP_OKAY or RMAP_ERROR). Depending on this response, the following statemachine decided the course of action: Action: Apply route-map match and return the result (RMAP_MATCH/RMAP_NOMATCH) State1: Receveived RMAP_MATCH THEN: If Routemap type is PERMIT, execute other rules if applicable, otherwise we PERMIT! Else: If Routemap type is DENY, we DENYMATCH right away State2: Received RMAP_NOMATCH, continue on to next route-map, otherwise, return DENYMATCH by default if nothing matched. With reference to PR 4078 (https://github.com/FRRouting/frr/pull/4078), we require a 3rd state because of the following situation: The issue - what if, the rule api needs to abort or ignore a rule?: "match evpn vni xx" route-map filter can be applied to incoming routes regardless of whether the tunnel type is vxlan or mpls.

The rules api can now return RMAP_NOOP (or another enum) to indicate that it encountered an invalid check, and needs to abort just that rule, but continue with other rules. Question: Do we repurpose an existing enum RMAP_OKAY or RMAP_ERROR as the 3rd state (or create a new enum like RMAP_NOOP)? RMAP_OKAY and RMAP_ERROR are used to return the result of set cmd. We chose to go with RMAP_NOOP (but open to ideas), as a way to bypass the rmap filter As a result we have a 3rd state: State3: Received RMAP_NOOP Then, proceed to other route-map, otherwise return RMAP_PERMITMATCH by default.

No-one is ever using this data so let's cut to the chase a bit and remove the pass through of data.

When calling route_map_finish, every place that we do we must first set the deletion event to NULL, or we will create an infinite loop, if we are using the delayed route-map application code. As such we might as well just make the route_map_finish code do this work, as that there is really no viable alternative here and route_map_finish should only be called on shutdown. This fixes an infinite loop in zebra on shutdown when there are route-maps. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

There are a variety of cli's associated with the 'set metric ...' command. The problem that we are experiencing is that not all the daemons support all the varieties of the set metric and the returned of NULL during the XXX_compile phase for these unsupported commands is causing issues. Modify the code base to only return NULL if we encounter a true parsing issue. Else we need to keep track if this metric applies to us or not. In the case of rip or ripngd if the metric passed to us is greater than 16 just turn it internally into a MAX_METRIC. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

This is a rather large mechanical commit that splits up the memory types defined in lib/memtypes.c and distributes them into *_memory.[ch] files in the individual daemons. The zebra change is slightly annoying because there is no nice place to put the #include "zebra_memory.h" statement. bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the library for its own use.

2016-03-22Quagga: Make routemap updates or deletes work for VRFsvivek
Updates to routemaps and delete of the routemap were not working properly for VRFs. This was because while routemaps are global, the routemap update processing timer and the processing were at the per-instance level. This approach was unable to handle processing for multiple instances as the routemap has no tracking of which instances are still pending processing. This lead to the processing happening correctly only for the first instance - which could be the default instance or some other instance. It could also result in reference to freed memory for an instance. The fix done is to make the update/delete processing also global and not per instance. This means that the route-map delay timer will be global and a global thread will handle the change (or delete) for all instances instead of spawning a separate thread for each instance. To support this, a global BGP command "bgp route-map delay-timer <value>" has been implemented. The existing command per-instance is not deleted but will update the global timer.

2009-07-19[bgpd] Stability fixes including bugs 397, 492Chris Caputo
I've spent the last several weeks working on stability fixes to bgpd. These patches fix all of the numerous crashes, assertion failures, memory leaks and memory stomping I could find. Valgrind was used extensively. Added new function bgp_exit() to help catch problems. If "debug bgp" is configured and bgpd exits with status of 0, statistics on remaining lib/memory.c allocations are printed to stderr. It is my hope that other developers will use this to stay on top of memory issues. Example questionable exit: bgpd: memstats: Current memory utilization in module LIB: bgpd: memstats: Link List : 6 bgpd: memstats: Link Node : 5 bgpd: memstats: Hash : 8 bgpd: memstats: Hash Bucket : 2 bgpd: memstats: Hash Index : 8 bgpd: memstats: Work queue : 3 bgpd: memstats: Work queue item : 2 bgpd: memstats: Work queue name string : 3 bgpd: memstats: Current memory utilization in module BGP: bgpd: memstats: BGP instance : 1 bgpd: memstats: BGP peer : 1 bgpd: memstats: BGP peer hostname : 1 bgpd: memstats: BGP attribute : 1 bgpd: memstats: BGP extra attributes : 1 bgpd: memstats: BGP aspath : 1 bgpd: memstats: BGP aspath str : 1 bgpd: memstats: BGP table : 24 bgpd: memstats: BGP node : 1 bgpd: memstats: BGP route : 1 bgpd: memstats: BGP synchronise : 8 bgpd: memstats: BGP Process queue : 1 bgpd: memstats: BGP node clear queue : 1 bgpd: memstats: NOTE: If configuration exists, utilization may be expected. Example clean exit: bgpd: memstats: No remaining tracked memory utilization. This patch fixes bug #397: "Invalid free in bgp_announce_check()". This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c: bgp_clear_route_node()". My apologies for not separating out these changes into individual patches. The complexity of doing so boggled what is left of my brain. I hope this is all still useful to the community.

Added "src" to struct nexthop. Added preferred src arg to nexthop_ipv4_add and rib_add_ipv4. * zebra/rt_netlink.c: (netlink_routing_table) set preferred source on netlink messages. (netlink_route_change) ditto (netlink_route_multipath) ditto. * zebra/rtread_getmsg.c: (handle_route_entry) added (NULL) src to rib_add_ipv4() call. * zebra/rtread_proc.c: (proc_route_read) ditto * zebra/zebra_rib.c: (nexthop_ipv4_add) add src argument. (nexthop_ipv4_ifindex_add) ditto (rib_add_ipv4) ditto (nexthop_active_check) Add route-map processing. * zebra/zebra_routemap.c: new file for zebra route-map commands. * zebra/zebra_vty.c: (ip_protocol_cmd) Apply route-map to protocol (vty_show_ip_route_detail) added "src" printing (vty_show_ip_route) ditto (show_ip_protocol_cmd) new command, list routemaps. (config_write_protocol) write out routemap protocl config. (zebra_vty_init) Install the new routemap protocol commands. * zebra/zserv.c: (zread_ipv4_add) added (NULL) src arg (zebra_init) init zebra route-maps. * zebra/zserv.h: add zebra_route_map_init

* (general) extern and static'ification of functions in code and header. Cleanup any definitions with unspecified arguments. Add casts for callback assignments where the callback is defined, typically, as passing void *, but the function being assigned has some other pointer type defined as its argument, as gcc complains about casts from void * to X* via function arguments. Fix some old K&R style function argument definitions. Add noreturn gcc attribute to some functions, as appropriate. Add unused gcc attribute to some functions (eg ones meant to help while debugging) Add guard defines to headers which were missing them. * command.c: (install_node) add const qualifier, still doesnt shut up the warning though, because of the double pointer. (cmp_node) ditto * keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived fromn vty.h ones to fix some of the (long) < 0 warnings. * thread.c: (various) use thread_empty (cpu_record_hash_key) should cast to uintptr_t, a stdint.h type * vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they removed from ospfd/ospf_vty.h * zebra.h: Move definition of ZEBRA_PORT to here, to remove dependence of lib on zebra/zserv.h

* version.h.in: (pid_output*) add const qualifier. * command.h: Change DEFUN func to take const char *[] rather than char **, to begin process of fixing compile warnings in lib/. Nearly all other changes in this commit follow from this change. * buffer.{c,h}: (buffer_write) pointer-arithmetic is gccism, take const void * and cast an automatic const char *p to it. (buffer_putstr) add const * command.c: (zencrypt) const qualifier (cmd_execute_command_real) ditto (cmd_execute_command_strict) ditto (config_log_file) ditto. Fix leak of getcwd() returned string. * memory.{c,h}: Add MTYPE_DISTRIBUTE_IFNAME for struct dist ifname. * distribute.{c,h}: Update with const qualifier. (distribute_free) use MTYPE_DISTRIBUTE_IFNAME (distribute_lookup) Cast to char *, note that it's ok. (distribute_hash_alloc) use MTYPE_DISTRIBUTE_IFNAME. (distribute_get) Cast to char *, note that it's ok. * filter.c: Update with const qualifier. * if.{c,h}: ditto. * if_rmap.{c,h}: ditto. (if_rmap_lookup) Cast to char *, note that it's ok. (if_rmap_get) ditto. * log.{c,h}: Update with const qualifier. * plist.{c,h}: ditto. * routemap.{c,h}: ditto. * smux.{c,h}: ditto. Fix some signed/unsigned comparisons. * sockopt.c: (getsockopt_cmsg_data) add return for error case. * vty.c: Update with const qualifier.

(at Technical University of Madrid as part of Euro6ix Project) Enhanced Route Server functionality and Route-Maps: * bgpd/bgpd.h: Modified 'struct peer' and 'struct bgp_filter' to support rs-clients. A 'struct bgp_table *rib' has been added to the first (to mantain a separated RIB for each rs-client) and two new route-maps have been added to the last (for import/export policies). Added the following #defines: RMAP_{IN|OUT|IMPORT|EXPORT|MAX}, PEER_RMAP_TYPE_{IMPORT|EXPORT} and BGP_CLEAR_SOFT_RSCLIENT. * bgpd/bgpd.c: Modified the functions that create/delete/etc peers in order to consider the new fields included in 'struct peer' for supporting rs-clients, i.e. the import/export route-maps and the 'struct bgp_table'. * bgpd/bgp_route.{ch}: Modified several functions related with receiving/sending announces in order to support the new Route Server capabilities. Function 'bgp_process' has been reorganized, creating an auxiliar function for best path selection ('bgp_best_selection'). Modified 'bgp_show' and 'bgp_show_route' for displaying information about any RIB (and not only the main bgp RIB). Added commands for displaying information about RS-clients RIBs: 'show bgp rsclient (A.B.C.D|X:X::X:X)', 'show bgp rsclient (A.B.C.D|X:X::X:X) X:X::X:X/M', etc * bgpd/bgp_table.{ch}: The structure 'struct bgp_table' now has two new fields: type (which can take the values BGP_TABLE_{MAIN|RSCLIENT}) and 'void *owner' which points to 'struct bgp' or 'struct peer' which owns the table. When creating a new bgp_table by default 'type=BGP_TABLE_MAIN' is set. * bgpd/bgp_vty.c: The commands 'neighbor ... route-server-client' and 'no neighbor ... route-server-client' now not only set/unset the flag PEER_FLAG_RSERVER_CLIENT, but they create/destroy the 'struct bgp_table' of the peer. Special actions are taken for peer_groups. Command 'neighbor ... route-map WORD (in|out)' now also supports two new kinds of route-map: 'import' and 'export'. Added commands 'clear bgp * rsclient', etc. These commands allow a new kind of soft_reconfig which affects only the RIB of the specified RS-client. Added commands 'show bgp rsclient summary', etc which display a summary of the rs-clients configured for the corresponding address family. * bgpd/bgp_routemap.c: A new match statement is available, 'match peer (A.B.C.D|X:X::X:X)'. This statement can only be used in import/export route-maps, and it matches when the peer who announces (when used in an import route-map) or is going to receive (when used in an export route-map) the route is the same than the one specified in the statement. For peer-groups the statement matches if the specified peer is member of the peer-group. A special version of the command, 'match peer local', matches with routes originated by the Route Server (defined with 'network ...', redistributed routes and default-originate). * lib/routemap.{ch}: Added a new clause 'call NAME' for use in route-maps. It jumps into the specified route-map and when it returns the first route-map ends if the called RM returns DENY_MATCH, or continues in other case.
