| | | | | | | | | | | | this fixes warnings from vtysh extract.pl by making sure the isis method files always 'work'. (previously, extract.pl would grab unselected isis method sources and then complain about missing headers)

| * | isisd: fixes 6/7: wrong next-hops from SPFPeter Szilagyi2010-02-033-29/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The forwarding table was filled with wrong next-hops, and which is even worse, it was done in a totally non-deterministic way. The next-hop set for an IP prefix by isisd was the neighbor IS from which the flooded LSP about the IP prefix was arrived. So, if an IS received all the LSPs through its, say, eth0 interface, all entries in the forwarding table contained the next IS reachable via eth0 as the next-hop. The solution is to propagate the correct next-hop further from node to node as the SPF algorithm traverses the graph and selects the next node to be added to the set of already covered nodes. Also, the construction of the tentative node list (the nodes where the shortest path is not known yet) was buggy: if a node was already a member of this list with a certain path cost, and an alternative path was found to it with a lower cost while processing a pseudo-node LSP, it was not added to the list. This way, the path selected by isisd for a certain prefix was the first one it encountered during the LSDB processing. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
| * | isisd: fixes 5/7: send proper LSP after DIS electionPeter Szilagyi2010-02-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After an IS has been elected as the Designated IS for a LAN, it did not refresh the content of the pseudo-node after a new node has been connected to the same LAN. Instead, the periodically reoriginated pseudo-node LSP still contained only those IS neighbors that were already present when the DIS election process was commenced. The fix for the problem schedules an LSP regeneration rather than just reoriginating the same LSP with the old content. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
| * | isisd: fixes 4/7: circuit state machinePeter Szilagyi2010-02-035-64/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | isisd has a so-called circuit state machine that takes care about the interface state changes, such as initializing, down, up. When an interface was brought down by a link failure, the interface information was deleted and set to NULL. When the link was restored later, the interface was looked up by the old pointer, but since it was cleared, it was never found again, resulting in an interface never entering the up state again. Also, the program regularly crashed because of a deleted pointer in the same context which was later accessed without any further checking. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>

Also fix the calls to these ioctls, as described in <net/bpf.h> in FreeBSD, NetBSD, and OpenBSD: * BIOCGBLEN, BIOCIMMEDIATE, BIOCSSEESENT (the parameter should be of type 'u_int') * BIOCPROMISC (there should be no parameters)

(bug #363) Should check for in_pktinfo for IRDP 2006-05-27 Paul Jakma <paul.jakma@sun.com> * configure.ac: General cleanup of header and type checks, introducing an internal define, QUAGGA_INCLUDES, to build up a list of stuff to include so as to avoid 'present but cant be compiled' warnings. Misc additional checks of things missing according to autoscan. Add LIBM, for bgpd's use of libm, so as to avoid burdening LIBS, and all the binaries, with libm linkage. Remove the bad practice of using m4 changequote(), just quote the []'s in the case statements properly. This should fix bugs 162, 303 and 178. * */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN, * bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().

| | | | | | | | | | | 2005-11-20 Paul Jakma <paul.jakma@sun.com> * (general) remove includes of very common system headers, these are already picked up by zebra.h. Further, including them before zebra.h messes up all our lovely (sarcasm) autoconf'd detecting of platform specific things. Recent addition of stdint.h to configure.ac and zebra.h appears particularly to throw up this problem.

Mark route as not in sync with zebra if it's changed. * isis_spf.c: Schedule route validating etc even if tent was empty. It's probably because we just don't have any adjacencies. * isisd.c: Write minimum spf interval into configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac: Add the test for Solaris least-privileges. Set defines for whether capabilities are supported and whether of the linux or solaris variety. Add missing-prototypes, missing-declarations, char-subscripts and cast-qual warnings to default cflags, cause Hasso enjoys warnings, and we really should clean the remaining ones up. (ie isisd..). * (*/*main.c) Update the zebra_capabilities_t arrays in the various daemons to match the changes made in lib/privs.h. * zebra.h: Solaris capabilities requires priv.h to be included. * privs.{c,h}: Add support for Solaris Least-Privileges. privs.h: Reduce some of the abstract capabilities, which do not have rough equivalents on both systems. Rename the net related caps to _NET, as they should have been in first place. (zprivs_terminate) should take the zebra_privs_t as argument so that it can update change pointer. Add an additional privilege state, ZPRIVS_UNKNOWN. * privs.c: (various capability functions) Add Solaris privileges variants. (zprivs_state) Use privs.c specific generic types to represent various capability/privilege related types, so that each can be typedef'd as appropriate on each platform. (zprivs_null_state) static added, to hold the state the null method should report (should be raised by default, and LOWERED if zprivs_terminate has been called) (zprivs_state_null) Report back the zprivs_null_state. (cap_map) Make it able to map abstract capability to multiple system capabilities. (zcaps2sys) Map to abstract capabilities to multiple system privileges/capabilities. (zprivs_init) move capability related init to seperate function, zprivs_caps_init. (zprivs_terminate) ditto, moved to zprivs_caps_terminate. Set the change_state callback to the NULL state, so the user can continue to run and use the callbacks.
