* eigrpd: kill eigrp_memory.h, use MTYPE_STATICDavid Lamparter2021-03-221-1/+3
| | | | | | | Same as previous commit -- convert most DEFINE_MTYPE into the _STATIC variant, and move the remaining non-static ones to appropriate places. Signed-off-by: David Lamparter <equinox@diac24.net>
* eigrpd: Correctly set the mtu for eigrp packets sentDonald Sharp2021-01-311-3/+15
| | | | | | | | | | | | | | This version of eigrp pre-calculated the eigrp metric to be a default of 1500 bytes, but unfortunately it had entered the byte order wrong. Modify the code to properly set the byte order according to the eigrp rfc as well as actually read in and transmit the mtu of the interface instead of hard coding it to 1500 bytes. Fixes: #7986 Signed-off-by: Donald Sharp <sharpd@nvidia.com>

* *: unify thread/event cancel macrosMark Stapp2020-10-231-1/+1
| | | | | | | | | Replace all lib/thread cancel macros, use thread_cancel() everywhere. Only the THREAD_OFF macro and thread_cancel() api are supported. Also adjust thread_cancel_async() to NULL caller's pointer (if present). Signed-off-by: Mark Stapp <mjs@voltanet.io>
* * : update signature of thread_cancel apiMark Stapp2020-10-231-1/+1
| | | | | | | | Change thread_cancel to take a ** to an event, NULL-check before dereferencing, and NULL the caller's pointer. Update many callers to use the new signature. Signed-off-by: Mark Stapp <mjs@voltanet.io>
* *: Use proper semantics for turning off threadDonald Sharp2020-10-121-2/+1
| | | | | | | | | | | | | We have this pattern in the code base: if (thread) THREAD_OFF(thread); If we look at THREAD_OFF we check to see if thread is non-null too. So we have a double check. This is unnecessary. Convert to just using THREAD_OFF Signed-off-by: Donald Sharp <sharpd@nvidia.com>

* eigrpd, ospfd, pimd: Fix assumption that interface may not be upDonald Sharp2019-12-041-31/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit: ddbf3e60604019d4b38d51226700e2244cc531b6 This commit modified the interface up handling code in ZAPI such that the zclient handled the decoding for you. Prior to this commit ospf assumed that it could use the old ifp pointer to know state before reading the stream. This lead to a situation where ospf would `smartly` track and do the right thing in this situation. This commit changed this assumption and in certain scenarios, say a interface was changed after it was already up would lead to situations where ospf would not properly handle the new interface up. Modify ospf to track data that is important to it in it's interface->info pointer. This code pattern was followed in both eigrp and pim. In eigrp's case it was just behaving weirdly in any event so fixing this pattern is not a big deal. In pim's case it was not properly using this so it's a no-op to fix.

* *: Convert from ->interface_up to the interface callbackDonald Sharp2019-09-191-0/+41
| | | | | | | For all the places we have a zclient->interface_up convert them to use the interface ifp_up callback instead. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* *: Switch all zclient->interface_add to interface create callbackDonald Sharp2019-09-191-0/+9
| | | | | | | Switch the zclient->interface_add functionality to have everyone use the interface create callback in lib/if.c Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* *: Add infrastructure to support zapi interface callbacksDonald Sharp2019-09-191-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | Start the conversion to allow zapi interface callbacks to be controlled like vrf creation/destruction/change callbacks. This will allow us to consolidate control into the interface.c instead of having each daemon read the stream and react accordingly. This will hopefully reduce a bunch of cut-n-paste stuff Create 4 new callback functions that will be controlled by lib/if.c create -> A upper level protocol receives an interface creation event The ifp is brand spanking newly created in the system. up -> A upper level protocol receives a interface up event This means the interface is up and ready to go. down -> A upper level protocol receives a interface down destroy -> A upper level protocol receives a destroy event This means to delete the pointers associated with it. At this point this is just boilerplate setup for future commits. There is no new functionality. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* eigrpd: Update eigrp_topology.c to not use VRF_DEFAULTDonald Sharp2019-08-071-3/+3
| | | | | | | Push out the pass in of struct eigrp to all functions in eigrp_topology.c so we do not lookup the eigrp pointer. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* eigrp: Make the eigrp_interface have a prefix instead of a *prefixDonald Sharp2019-02-111-6/+6
| | | | | | | | | The prefix data structure was being freed yet still needed in the future and it's a fundamental part of the eigrp_interface data structure let's keep it there instead of having it be deleted and then not. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* eigrpd: Fix eigrp crash on shut of a interfaceDonald Sharp2018-09-221-4/+2
| | | | | | | | | | | | | The eigrp interface structure was storing a pointer to the connected interface structure and on shutdown of an interface this would cause zebra to call eigrp back with a shutdown of that interface, as part of that operation the connected interface structure is being deleted, but eigrp was keeping a pointer to the connected structure. At the same time we were keeping the address of the connected structure and this is all we need, so keep a copy of that data and use that instead.

* *: Convert list_delete(struct list *) to ** to allow nullingDonald Sharp2017-10-051-2/+2
| | | | | | | | | | | | | | | | | | | Convert the list_delete(struct list *) function to use struct list **. This is to allow the list pointer to be nulled. I keep running into uses of this list_delete function where we forget to set the returned pointer to NULL and attempt to use it and then experience a crash, usually after the developer has long since left the building. Let's make the api explicit in it setting the list pointer to null. Cynical Prediction: This code will expose a attempt to use the NULL'ed list pointer in some obscure bit of code.

* eigrpd: Remove ei mapping to connected routesDonald Sharp2017-10-031-210/+54
| | | | | | | | | | We need one struct eigrp_interface per ifp structure not a ifp->info structure with a ei per connected. Some minor code cleanup as well with macros and their weird usage. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* eigrpd: Start fixing eigrp_interfaceDonald Sharp2017-10-031-1/+1
| | | | | | | | | | | | | | | The EIGRP interface handling code created 2 levels of interface information, the ei( created per *connected* address?????) and the ifp->info pointer. Start the combination of pushing these together and cleaning up the weirdness that is these two data structures. This commit probably breaks eigrp's handling of interfaces.
