Log:
Several fixes to ARP and route locking, that were done during 6.0 release
cycle, and are also applicable to RELENG_5:
o Make rt_check() return a locked rtentry.
o Make rt_check() function more strict:
- rt0 passed to rt_check() must not be NULL, assert this.
- rt returned by rt_check() must be valid locked rtentry,
if no error occured.
o Modify callers, so that they never pass NULL rt0
to rt_check().
o Modify callers, so that they unlock rtentry.
o Fix races in ARP code. See if_ether.c 1.139 for more information.
o Fix LORs in ARP code. See if_ether.c 1.141 for more information.
o Lock rtentry before dropping radix lock.
o Send published ARP replies only on correct interface. [1]
o Drop rtentry lock before calling rt_getifa(). [2]
o Fixes to rt_setgate():
- To avoid recursive rtentry locking.
- Do not change routes in case of failure.
- Return EADDRINUSE instead of bogus EDQUOT [3]
