2012-12-12isisd: do not add >63 IP addresses to helloDavid Lamparter
RFC1195 s4.2 "Multiple IP Addresses per Interface" explicitly forbids us from adding multiple tuples of IP addresses, putting a hard cutoff at 63 IP addresses. * isisd/isis_tlv.c: cut off (and return success) at 63 addrs. Signed-off-by: David Lamparter <equinox@opensourcerouting.org> Tested-by: Martin Winter <mwinter@opensourcerouting.org>
2012-11-05isisd: clock_gettime() -> quagga_gettime() conversion.Hasso Tepper
* isisd/isis_spf.c: Use portable quagga_gettime() like the rest of the Quagga code. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-10-25*: use array_size() helper macroBalaji.G
Use the array_size() helper macro. Replaces several instances of local macros with the same definition. Reviewed-by: Scott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-10-25isisd: don't overrun list of protocolsDavid Lamparter
isisd currently has a list of supported protocols as a fixed array of size 4. this can be overran, leading to an overwrite of the ipv4_addrs pointer. * isisd/isis_pdu.c: don't accept more protocols than there's space for Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-10-25isisd: don't process invalid prefixes from TLVsDavid Lamparter
it's possible to feed invalid prefixes (1.2.3.4/40 or dead::beef/200) on IS-IS. if this is not checked, it will later cause an assert in processing. let's simply abort processing the TLV if the prefix is invalid. * isisd/isis_tlv.c: check prefix lengths for validity Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-10-25isisd: pull up invalid prefix assert()David Lamparter
processing invalid prefixes causes isisd to assert() or otherwise misbehave in ip_masklen/apply_mask. pull up the assert() to indicate better there's broken data in isisd's LSDB. * isisd/isis_spf.c: assert() prefix lengths Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-10-25isisd: fix null pointer dereference in send_lsp()Avneesh Sachdev
* isisd/isis_pdu.c: (send_lsp) Handle case where there are no LSPs on the LSP transmission queue. This can happen if, for instance, the queue is cleared because of protocol events before the send_lsp thread gets a chance to run.
2012-10-25isisd: tighten checks on ISIS pdu lengthAvneesh Sachdev
* isisd/isis_pdu.c: Fix problem where isisd would crash if it received a LAN IIH with the 'pdu length' field set to zero. Similar problems can occur in parsing other ISIS PDUs as well -- check that the PDU length in an ISIS hello, LSP or SNP packet is at least as big as the size of the respective fixed header.
2012-06-25build: allow configure and build in a separate directoryVincent Bernat
Some .h files in lib/ are autogenerated. The search path should include the build directory and the source directory. They usually match but sometimes, they may be different. For example: $ mkdir build $ cd build $ ../configure $ make
2012-06-21isisd: fix typo in topology generator (BZ#731)David Lamparter
There was a "lsp->" missing before "level" in line 2416. (introduced by git commit e38e0df) Reported-by: Seblu <seblu@seblu.net> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-04-16quagga: option "-z" ("--socket <path>") addedVyacheslav Trushkin

2012-04-11isisd: reapply patch to fix zebra protocolAvneesh Sachdev
Reapply the bits of revision b4e45f6 that pertain to isisd. That is: git log -n 1 -p b4e45f6 -- isisd These were dropped in the merge with the Google ISIS code (14d2bbaa). The commit message for b4e45f6 is: fix zebra protocol after MP-BGP changes The previous commits modified both zebra and bgpd for additional SAFI field, but not any other routing daemon, which led to zebra daemon crashing with failed assertion.

2012-04-07isisd: add Google's changes to IS-ISJosh Bailey
2010-04-28isisd: change ISIS_METHOD to use C preprocessorDavid Lamparter
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)
2009-12-21lib: make some structures constantStephen Hemminger

2009-12-03isisd: fix BPF ioctl() calls, treat "true" and "false" as reservedDavid Ward
Avoid a potential conflict with the C99 defines 'true' and 'false' found in <stdbool.h> by choosing better variable names. 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)
2009-08-13all: check return value from daemon() callStephen Hemminger
* */*main.c: (main) Current versions of Gcc warn if the return value for daemon() is not checked. So add a simple test and exit on failure.
2009-06-19[cleanup] convert bzero() deprecated by POSIX to memset()Jeremy Jackson
autoscan 2.62 complains about bzero(), so a good fix nowadays is to just replace it.
2009-06-12[cleanup] Make command nodes staticStephen Hemminger
The cmd_nodes used to configure vty, can mostly be static so (basic data hiding 101).

2007-08-07[isisd] Add support for Solaris DLPIPaul Jakma
2007-08-07 James Carlson <james.d.carlson@sun.com> * configure.ac: Added support for separate link-layer access mechanisms in isisd. * isis_network.c: split up into isis_bpf.c, isis_dlpi.c, and isis_pfpacket.c, selected by autoconf, and added DLPI support. * (general) Fixed to allow compilation and use on Solaris.
2007-05-10[autoconf] bugs 162,303,178: Fix 'present but can not be compiled' warningsPaul Jakma
2007-05-09 Paul Jakma <paul.jakma@sun.com> * configure.ac: sys/conf.h depends on sys/param.h, at least on FBSD 6.2. (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().
2006-12-08[isisd] Fix compiler warnings and allow v4-only compilationPaul Jakma

2006-10-15[daemon startup] Add --dry-run/-C argument to daemons, to check config file ↵Paul Jakma
syntax 2006-10-04 Oliver Hookins <ohookins@gmail.com> * bgpd/bgp_main.c: Add configuration check option, with '-C' rather than '-c' for consistency between daemons. * isisd/isis_main.c: ditto * ospf6d/ospf6_main.c: ditto * ospfd/ospf_main.c: ditto * ripngd/ripng_main.c: ditto * vtysh/vtysh_main.c: ditto * ripd/rip_main.c: Change the config check option to '-C' and tidy up the code. * zebra/main.c: ditto 2006-10-04 Stergiakis Alexandros <astergiakis@antcor.com> * ripd/rip_main.c: This trivial patch introduces a new command-line option '-c', which instructs zebra/ripd to check its configuration file for validity, print any error message, and then exit. This is useful when the configuration file is edited by hand or otherwise, and you simply want to validate it without any other effect. * zebra/main.c: ditto
2006-01-17[zserv] fix up custom isisd and bgpd Zserv functions for new format.paul
2006-01-17 Paul Jakma <paul.jakma@sun.com> * bgp_nexthop.c: (zlookup_read*) convert to new Zserv format. (zlookup_query_ipv6) ditto. (bgp_import_check) ditto. * isis_zebra.c: (isis_zebra_route_add_ipv4) fix for new zserv format.
2005-11-20[isisd] remove includes of common system headers.paul
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.
2005-10-01 * isis_adjacency.c: Stop expire timer while deleting adjacency.hasso
* isis_events.c: Stop pseudo LSP thread while resigning circuit from level. * isis_route.c: Fix compiling with EXTREME_DEBUG. 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.
2005-09-28 * *.c: Massive cleanup of lists loops. Stop abusing ALL_LIST_ELEMENTS.hasso
Replace XMALLOC + memset with XCALLOC. Fix some indentation issues. The only really significant change is simplified isis_delete_adj function in isis_adjacency.c.
2005-09-28 * isis_dynh.c, isisd.h: Implement dynamic hostname cache cleanup.hasso
* isis_lsp.c: Refresh dynamic hostname in the cache while refreshing topology LSP.
2005-09-28 * isis_lsp.c: Make topology generator generate TE TLVs if necessary.hasso
Also take care of inserting dynamic hostname of topology TLVs into cache.
2005-09-26 * isis_spf.c: Changing cost from uint16_t to uint32_t. Unsethasso
ISIS_ROUTE_FLAG_ACTIVE flag before running SPF. * isisd.[ch]: Separate route tables for different levels. SPF is done separately, but in case of L1L2 area they have to be merged. * isis_zebra.c: Set/unset ISIS_ROUTE_FLAG_ZEBRA_SYNC flag correctly in case of adding/removing IPv4 routes. * zebra_route.c: Rework route validating process. Merging L1 and L2 tables in case of L1L2 area. In short - many changes to make SPF work more correctly, add/remove to/from RIB also works now. It's still very far from perfect though.
2005-09-26 * isis_spf.[ch]: Added TE TLVs to the SPF process. It seems to workhasso
mostly, but needs certainly much more testing, especially transition situation.
2005-09-26 * isis_lsp.c: Put correct metric info into TE TLV's. Wide metric ishasso
used only if only wide metric style (extended TLV's) is in use.
2005-09-26 * isis_tlv.[ch]: New function tlv_add_in_addr() to put just one IPv4hasso
address into TLV. Used for IPv4 address TLV (in case of LSP) and TE router ID TLV. * isis_lsp.c: Use tlv_add_in_addr() and include router ID in LSP.
2005-09-26 * isis_lsp.c: Support for originating TE IS and IPv4 TLV's. No any subhasso
TLV handling yet.
