are only visible if _SOLARIS_C_SOURCE is defined.
Note thar FreeBSD stat() and fstat() are 64-bit functions now and Solaris
still persists with both 32- and 64-bit versions. When I query this, I am
referred to: <http://www.unix.org/version2/whatsnew/lfs20mar.html>.
But when you look at the main page of unix.org you will see that the
Single Unix Specification <http://www.unix.org/version3/> is the most
recent standard they are pushing. And there are no stat64() fstat64()
functions defined there. I guess this just goes to prove that there are so
many standards, you can take your pick.
The cyclic timer is a high-resolution timer allows timeouts at nanosecond
intervals where hardware support is available. Typically on i386 there
is no HPET (high performance event timer) like the one Intel started
specifying some time in 2004, so the best that tye cyclic timer subsystem
can do is run at Hz.
The cyclic timer code itself is ported from OpenSolaris and is covered
by the CDDL, so it is only loaded as a module. This function type definition
is used in machine-dependent code to provide a hook for the module to
register it's callback function.
if _SOLARIS_C_SOURCE is defined.
Add two function prototypes which are required to feed high-resolution
times to DTrace. DTrace requires it's own functions with the dtrace_
prefix so that it knows not to try and trace them. This is a rule that
code executed from the DTrace probe context must obey.
The two functions are only be compiled if the KDTRACE option is defined
to compile in kernel support for loading the DTrace modules.
These are only defined if _SOLARIS_C_SOURCE is defined, so they don't
polute the FreeBSD compile environment.
They are used all over the OpenSolaris source, so defining them here
removes the need to continually resolve differences in FreeBSD system
haeder files from Solaris header files.
were unused or already in if_var.h so add if_name() to if_var.h and
remove net_osdep.h along with all references to it.
Longer term we may want to kill off if_name() entierly since all modern
BSDs have if_xname variables rendering it unnecessicary.
the notify structs. Fix messages in isp_got_msg_fc to print out the
loop id of the sender- not the wwpn which will be synthesized later,
if possible, in the outer layers. Put in debug printouts to pair
a notify ack to a notify so one can see the start/close of an
immediate notify event. Put in spsace for TASK MANAGEMENT response
flags (which we don't do yet).
on output frames.
Many people were confused with not working CARP, ng_bridge(4)
and other subsystems, because ng_ether(4) overwritten source
MAC address.
We have to adjust curthread's state enough so that it appears to be
in a poll(2) or select(2) call so that selrecord() will work and then
teardown that state after calling sopoll().
- Fix some minor nits in nearby ncp_sock_rselect() and in the identical
nbssn_rselect() function in the netsmb code:
- Don't call nb_poll()/ncp_poll() now that ncp_poll() already fakes up
poll(2) state since the rselect() functions already do that. Just
invoke sopoll() directly.
- To make things slightly more intuitive, store the results of sopoll()
in a new 'revents' variable rather than 'error' since that's what
sopoll() actually returns.
- If the requested timeout time has been exceeded by the time we get
ready to block, then return EWOULDBLOCK rather than 0 to signal a
timeout as this is what the calling code expects.

interface, do not just assign -1 to tag because it breaks the logic of
the code to follow. The better way is to handle this case as an unsupported
protocol and return unless INVARIANTS is in effect and we can panic.
Panic is good there because the scenario can happen only because of a
coding error elsewhere.
We also should show the interface name in the panic message for easier
debugging of the problem, should it ever emerge.

as it tried to solve:
- it smuggled hidden 802.1q details into otherwise protocol-neutral code;
- it put an important code consistency check under DEBUG, which was never
defined by anyone but a developer hacking this file for the moment;
- lastly, the former bcopy() call had been correct as long as the "dead"
code was there.
(A new version of the fix for tag of -1 to come in the next commit.)

- if_em.c. Merged manually, viewing diff between new vendor
driver and previous one. This was an easy task, because
most changes between 5.1.5 and 6.0.5 are bugfixes taken
from FreeBSD.
- if_em_hw.h. Dropped in from vendor, and then restored
revisions 1.16, 1.17, 1.18.
- if_em_hw.c. Dropped in from vendor, and then restored
revision 1.15.
- if_em_osdep.h. Added new required macros from vendor file
and add a hack against define namespace mangling in
if_em_hw.h. Intel made another hack, but I prefer mine.

Another file called systrace_args.c is generated. This will be compiled
into systrace and is used to map the syscall arguments into the 64-bit

alloc'ing mbufs so that there is less error handling required.
- Go ahead and account for the data space in the first mbuf before entering
the loop to alloc more mbuf's. This simplifies the loop logic and avoids
confusing Coverity.

tcp_twstart(), but not to the other, tcp_detach(), as the socket is
already being torn down and therefore there are no listeners. This avoids
a panic if kqueue state is registered on the socket at close(), and
eliminates to XXX comments. There is one case remaining in which
tcp_discardcb() reaches up to the socket layer as part of the TCP host
cache, which would be good to avoid.

vfs_rel() on the mountpoint if the MAC checks fail in kern_statfs() and
kern_fstatfs(). Similarly, don't perform an extra vfs_rel() if we get
a doomed vnode in kern_fstatfs(), and handle the case of mp being NULL
(for some doomed vnodes) by conditionalizing the vfs_rel() in
kern_fstatfs() on mp != NULL.
