KASSERT() that we don't.
When calculating the load address for the interpreter (e.g. ld.elf_so),
we need to take into account wether the exec'd process will run with
topdown memory or bottom up. We can not use the current vmspace's flags
to test for that, as this happens too early. Luckily the execpack already
knows what the new state will be later, so instead of testing the current
vmspace, pass the info as additional argument to struct emul
e_vm_default_addr.
Fix all such functions and adopt all callers.
- fix missing/inconsistent abbreviations
- set dst only if we are using localtime.
- properly check for errors where there were missing checks
- handle errno properly including saving and restoring.
XN (eXecute Never) appropriately.
The XN logic is inconsistent and could do with changing to XN always set
and cleared for VM_PROT_EXECUTE (or the inverse) everywhere.
pointers. Ensure that we have the correct "old" values before setting
new values, for both "intall" and "deinstall".

lltable and llentry were introduced to replace ARP cache data structure
for further restructuring of the routing table: L2 nexthop cache
separation. This change replaces the NDP cache data structure
(llinfo_nd6) with them as well as ARP.
One noticeable change is for neighbor cache GC mechanism that was
introduced to prevent IPv6 DoS attacks. net.inet6.ip6.neighborgcthresh
was the max number of caches that we store in the system. After
introducing lltable/llentry, the value is changed to be per-interface
basis because lltable/llentry stores neighbor caches in each interface
separately. And the change brings one degradation; the old GC mechanism
dropped exceeded packets based on LRU while the new implementation drops
packets in order from the beginning of lltable (a hash table + linked
lists). It would be improved in the future.
Added functions in in6.c come from FreeBSD (as of r286629) and are
tweaked for NetBSD.
Proposed on tech-kern and tech-net.
for the files in the cdroms to be built. For now we copy the timestamp of
<sys/param.h>. We could set an absolute timestamp too like -T 0 for the epoch.
