against rules. It definitely doesn't need to know about kernel internals,
such as 'struct ifaddr'. What it does with ifaddr, is that it only takes
ifa_addr member of it, and treats it as sockaddr, while it is only a pointer
to sockaddr. Fortunately, sizeof(struct ifaddr) > sizeof(struct sockaddr_in6),
so no problems arise.
Fix that declaring a private struct ifaddr in ipftest(1) and stop including
if_var.h.

leak kernel internal stuff, reconnect ifmcstat(1) back to build. However,
disable kvm(3) support in it, since it requires uncovering tons of _KERNEL
defined declarations, which can be achieved either uncovering them globally
or providing dirty hacks such as _WANT_IFADDR. If anyone demands an
ifmcstat-like kvm-based tool, please take the code out of usr.sbin/ifmstat
and create a tool in src/tools/tools.

- Preserve name 'struct mld_ifinfo' for a new structure, that will be stable

- Make sysctl_mld_ifinfo() return the new 'struct mld_ifinfo', instead of

On POSIX conformant systems, shutdown() should return ENOTCONN when not
connected. We attempted to fix this once (kern/84761), but this change
got backed out because it 'breaks code' (r150155).
I just reapplied the patch and indeed, syslogd fails on startup. Make it
easier to re-enable this change in the future by paching up syslogd to
do the right thing.

If there is garbage in the flags field, it can sometimes include a
set CDAI_FLAG_STORE flag, which may cause either an error or
perhaps result in overwriting the field that was intended to be
read.
sys/cam/cam_ccb.h:
Add a new flag to the XPT_DEV_ADVINFO CCB, CDAI_FLAG_NONE,
that callers can use to set the flags field when no store
is desired.
sys/cam/scsi/scsi_enc_ses.c:
In ses_setphyspath_callback(), explicitly set the
XPT_DEV_ADVINFO flags to CDAI_FLAG_NONE when fetching the
physical path information. Instead of ORing in the
CDAI_FLAG_STORE flag when storing the physical path, set
the flags field to CDAI_FLAG_STORE.
sys/cam/scsi/scsi_sa.c:
Set the XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE when
fetching extended inquiry information.
sys/cam/scsi/scsi_da.c:
When storing extended READ CAPACITY information, set the
XPT_DEV_ADVINFO flags field to CDAI_FLAG_STORE instead of
ORing it into a field that isn't initialized.
sys/dev/mpr/mpr_sas.c,
sys/dev/mps/mps_sas.c:
When fetching extended READ CAPACITY information, set the
XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE instead of
setting it to 0.
