Simplify
We can assume that rt_ifp is always non-NULL.
Sending a routing message (RTM_ADD) on adding an llentry
A message used to be sent on adding a cloned route. Restore the
behavior for backward compatibility.
Requested by ryo@
Drop RTF_CONNECTED from a result of RTM_GET for ARP/NDP entries
ARP/NDP entries aren't connected routes.
Reported by ryo@
Support -c <count> option for route monitor
route command exits if it receives <count> routing messages where
<count> is a value specified by -c.
The option is useful to get only particular message(s) in a test script.
Test routing messages emitted on operations of ARP/NDP entries
Do netstat -a for an appropriate protocol
Add missing declarations for cleanup
Set net.inet.arp.keep only if it's required
Don't create a permanent L2 cache entry on adding an address to an interface
It was created to copy FreeBSD, however actually the cache isn't
necessary. Remove it to simplify the code and reduce the cost to
maintain it (e.g., keep a consistency with a corresponding local
route).
Fix typo
Fix in_lltable_match_prefix
The function has not been used but will be used soon.
Remove unused function (nd6_rem_ifa_lle)
Allow in6_lltable_free_entry to be called without holding the afdata lock of ifp as well as in_lltable_free_entry
This behavior is a bit odd and should be fixed in the future...
Purge ARP/NDP entries on an interface when the interface is down
Fix PR kern/51179
Purge all related L2 caches on removing a route
The change addresses situations similar to PR 51179.
Purge L2 caches on changing an interface of a route
The change addresses situations similar to PR 51179.
Test implicit removals of ARP/NDP entries
One test case reproudces PR 51179.
Fix build of kernels without both INET and INET6
Tweak lltable_sysctl_dumparp
- Rename lltable_sysctl_dumparp to lltable_sysctl_dump
  because it's not only for ARP
- Enable it not only for INET but also for INET6
Fix usage of routing messages on arp -d and ndp -d
It didn't work as we expected; we should set RTA_GATEWAY not
RTA_IFP on RTM_GET to return an if_index and the kernel should
use it on RTM_DELETE.
Improve backward compatibility of (fake) routing messages on adding an ARP/NDP entry
A message originally included only DST and GATEWAY. Restore it.
Fix ifdef; care about a case w/ INET6 and w/o INET
Drop RTF_UP from a routing message of a deleted ARP/NDP entry
Check existence of ARP/NDP entries
Checking ARP/NDP entries is valid rather than checking routes.
Fix wrong comment
Drop RTF_LLINFO flag (now it's RTF_LLDATA) from local routes
They don't have llinfo anymore. And also the change fixes unexpected
behavior of ARP proxy.
Restore ARP/NDP entries to route show and netstat -r
Requested by dyoung@ some time ago
Enable to remove multiple ARP/NDP entries for one destination
The kernel can have multiple ARP/NDP entries which have an indentical
destination on different interfaces. This is normal and can be
reproduce easily by ping -I or ping6 -S. We should be able to remove
such entries.
arp -d <ip> and ndp -d <ip> are changed to fetch all ARP/NDP entries
and remove matched entries. So we can remove multiple entries
described above. This fetch all and selective removal behavior is
the same as arp <ip> and ndp <ip>; they also do fetch all entries
and show only matched entries.
Related to PR 51179
Check if ARP/NDP entries are purged when a related route is deleted
