The sendfile(2) allows to send extra data from userspace before the file
data (headers). Historically the size of the headers was not checked
against the socket buffer space. Application could easily overcommit the
socket buffer space.
With the new sendfile (r293439) the problem remained, but a KASSERT was
inserted that checked that amount of data written to the socket matches
its space. In case when size of headers is bigger that socket space,
KASSERT fires. Without INVARIANTS the new sendfile won't panic, but
would report incorrect amount of bytes sent.
o With this change, the headers copyin is moved down into the cycle, after
the sbspace() check. The uio size is trimmed by socket space there,
which fixes the overcommit problem and its consequences.
o The compatibility handling for FreeBSD 4 sendfile headers API is pushed
up the stack to syscall wrappers. This required a copy and paste of the
code, but in turn this allowed to remove extra stack carried parameter
from fo_sendfile_t, and embrace entire compat code into #ifdef. If in
future we got more fo_sendfile_t function, the copy and paste level would

Do not override top level CFLAGS in libexec/dma

Do not try to install a default route for each interface found, because
only the first one will actually work and all the others just result in
errors (which would get printed but otherwise ignored).
Instead, wait until we make a choice of which interface will be used to
mount the rootfs, and install the default route associated with it (if any).
After doing the md_mount() call to obtain the needed info, remove the
default route again, and transcribe the route info into the nfs_diskless
structure. If the system eventually chooses to mount the nfs rootfs, the
default route will be installed again when the nfs_diskless code
re-initializes the interface.
The theory here is that since we can only have one default route, the one
most likely to be correct for mounting the rootfs is the one that was
delivered along with the rootpath option.

Stop setting the default route to the IP of the interface itself when the
bootp/dhcp server doesn't provide a router option. Doing so prevents
setting defaultrouter=<ip> in rc.conf (it fails because there's already
a bogus default route installed by bootpc_init).
When an admin wants to use this style of proxy arp on an interface, the
proper mechanism is to set the "use-lease-addr-for-default-route" flag
in the dhcp server config. That causes the lease address to be delivered
in the routers option, and the normal handling of the routers option will
then install the self-ip as the default route.

Switch bootpc_adjust_interface() from returning int to void. Its one caller
doesn't check for errors, and all the errors that can happen result in it
calling panic anyway, except for one that's really more of a warning (and
is going to disappear on an upcoming commit anyway).

Set ifctx->gotrootpath=1 only when the root path came from the dhcp/bootp
server (and not when it came from a fallback method such as the ROOTDEVNAME
option). This makes the code in bootpc_init() choose the first interface
that provided a rootpath name. Previously it was choosing the first
interface that got an IP address, which could be on a different and
potentially unreachable subnet than the server providing the rootfs.
If the rootpath name actually does come from a fallback source, then the
code continues to use the first interface in the list that got configured.

[libcxx] Enable noexcept for GCC 4.6 and greater
Summary:
This patch allows GCC 4.6 and above to use `noexcept` as opposed to
`throw()`.
Is it an ABI safe change to suddenly switch on `noexcept`? I imagine
it must be because it's disabled in w/ clang in C++03 but not C++11.

Split the global taskqueue used to process all UFS trim completions,
into per-mount taskqueue with the private taskqueue processing thread.
This allows to drain the taskqueue on unmount, to ensure that all
TRIMs are finished before mount structures are freed.
But just draining the taskqueue where TRIM biodone geom-up completions
are processed is not enough, since ffs_blkfree(), called by the task,
might result in more writes. Count inflight delayed blkfree's and
pause() unmount until the counter drains as well.

Compile libcxxrt as C++11, since it is only really used in combination
with libc++, which is also C++11. Also change one _Static_assert (which
is really C11) back into static_assert, like upstream.
This should help when compiling libcxxrt with newer versions of gcc,
which refuse to recognize any form of static assertions, if not
compiling for C++11 or higher.
While here, add -nostdinc++ to CFLAGS, to prevent picking up any C++
headers outside the source tree.

Plug leak in m_unshare.
m_unshare passes on the source mbuf's flags as-is to m_getcl and this
results in a leak if the flags include M_NOFREE. The fix is to clear
the bits not listed in M_COPYALL before calling m_getcl. M_RDONLY
should probably be filtered out too but that's outside the scope of this
fix.
Add assertions in the zone_mbuf and zone_pack ctors to catch similar
bugs.
Update netmap_get_mbuf to not pass M_NOFREE to m_getcl. It's not clear
what the original code was trying to do but it's likely incorrect.
Updated code is no different functionally but it avoids the newly added
assertions.
