from int to int64.
MSDN says that SMB_SET_FILE_END_OF_FILE_INFO uses signed 64-bit integer
to specify offset, but since smbfs_smb_setfsize() has used plain int,
a value was truncated in case when offset was larger than 2G.
https://msdn.microsoft.com/en-us/library/ff469975.aspx
In particular, now `truncate -s 10G` will work correctly on the mounted
SMB share.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c:
If available, record the physical path of a vdev in ZFS meta-data.
Do this both when opening the vdev, and when receiving an attribute
change notification from GEOM.
Make vdev_geom_close() synchronous instead of deferring its work to
a GEOM event handler. There is no benefit to deferring the work and
this prevents a future open call from referencing a consumer that is
scheduled for destruction. The close followed by an immediate open
will occur during a vdev reprobe triggered by any type of I/O error.
Consolidate vdev_geom_close() and vdev_geom_detach() into
vdev_geom_close() and vdev_geom_close_locked(). This also moves the
cross linking operations between vdev and GEOM consumer into a
single place (linking in vdev_geom_attach() and unlinking in
vdev_geom_close_locked()).

member secsz was a uint16_t
sys/boot/zfs/zfs.c has a probe args structure member, secsz, that is a
uint16_t for media sector size; it is used as an argument for ioctl()
at line 484. however, this ioctl writes 32 bits of data (u_int *) and
therefore this ioctl will overwrite and corrupt 16 bits of memory.
other use cases seem to use correct u_int type for secsz.

Some variables like PATH call a function when modified. Make sure to call
this also when leaving a function where such a variable was made local.
Make sure to restore local variables before shellparam, so getopts state is
not clobbered.
in6_selectsrc() has 2 class of users: socket-based one (raw/udp/pcb/etc) and
socket-less (ND code). The main reason for that change is inability to
specify non-default FIB for callers w/o socket since (internally) inpcb
is used to determine fib.
As as result, add 2 wrappers for in6_selectsrc() (making in6_selectsrc()
static):
1) in6_selectsrc_socket() for the former class. Embed scope_ambiguous check
along with returning hop limit when needed.
2) in6_selectsrc_addr() for the latter case. Add 'fibnum' argument and
pass IPv6 address w/ explicitly specified scope as separate argument.

The only piece of information that is required is rt_flags subset.
In particular, if_loop() requires RTF_REJECT and RTF_BLACKHOLE flags
to check if this particular mbuf needs to be dropped (and what
error should be returned).
Note that if_loop() will always return EHOSTUNREACH for "reject" routes
regardless of RTF_HOST flag existence. This is due to upcoming routing
changes where RTF_HOST value won't be available as lookup result.
All other functions require RTF_GATEWAY flag to check if they need
to return EHOSTUNREACH instead of EHOSTDOWN error.
There are 11 places where non-zero 'struct route' is passed to if_output().
For most of the callers (forwarding, bpf, arp) does not care about exact
error value. In fact, the only place where this result is propagated
is ip_output(). (ip6_output() passes NULL route to nd6_output_ifp()).
Given that, add 3 new 'struct route' flags (RT_REJECT, RT_BLACKHOLE and
RT_IS_GW) and inline function (rt_update_ro_flags()) to copy necessary
rte flags to ro_flags. Call this function in ip_output() after looking up/
verifying rte.

This check was added in initial? netinet6/ import
back in 1999 (r53541).
It effectively became unnecessary after 'address/prefix clean-ups'
KAME commit 90ff8792e676132096a440dd787f99a5a5860ee8 (github) in 2001
(merged to FreeBSD in r78064) where prefix check was added to
nd6_prefix_onlink(). Similar IPv4 check (in_addroute() was added
in r137628).
Additionally, the right plance for this (or similar) check is the prefix
addition code (nd6_prefix_onlink(), nd6_prefix_onlink_rtrequest(),
in_addprefix() or rtinit()), but not the generic radix insert routine.
Such handler should pass different set of variables, instead
of directly providing 2 locked route entries.
Given that it hasn't been really used since at least 2012, remove
current code.
Will re-add it after finishing most major routing-related changes.

r282971 attempted to fix this problem by decrementing cv_waiters after
waking up from sleeping on a condition variable, but this can result in
a use-after-free if the CV is freed before all woken threads have had a
chance to run. Instead, avoid incrementing cv_waiters past INT_MAX, and
have cv_signal() explicitly check for sleeping threads once cv_waiters has
reached this bound.
