Extend fixes made in r278103 and r38754 by copying the complete packet
header and not only partial flags and fields. Firewalls can attach
classification tags to the outgoing mbufs which should be copied to
all the new fragments. Else only the first fragment will be let
through by the firewall. This can easily be tested by sending a large
ping packet through a firewall. It was also discovered that VLAN
related flags and fields should be copied for packets traversing
through VLANs. This is all handled by "m_dup_pkthdr()".
Regarding the MAC policy check in ip_fragment(), the tag provided by
the originating mbuf is copied instead of using the default one
provided by m_gethdr().

Update this driver to not save copies of registers that are no longer
used after r281874. While here, also update it to always write the
parent's PCI bus number to the primary bus register.
Simplify hang detection by stealing the techniques used in ixl(4) and
applying them to em(4).
Rely on iterations through the local timer, and the tx queue state to
determine if an actual hang has occurred. Any time a descriptor is used
(packet sent), the tx queue is flagged as busy. Then when txeof runs, it
either clears the flag when all is clean, or resets it to 1 if ANY are
cleaned, if nothing is cleaned it increments the flag.
Local timer simply checks to see if busy ever reaches MAX (10, which
is compile time configurable), and then sets it as HUNG, at that point
there is one more timer cycle in which to have any cleans, if not a
watchdog reset will occur.
In case of an output error, continue with the next net, don't try to
continue sending on the same net.
This fixes a bug where an invalid mbuf chain was constructed, if a
full size frame of control chunks should be sent and there is a
output error.
Based on a discussion with rrs@, change move to the next net. This fixes
the bug and improves the behaviour.
Thanks to Irene Ruengeler for spending a lot of time in narrowing this
problem down.

Add support for reading MAM attributes to camcontrol(8) and libcam(3).
MAM is Medium Auxiliary Memory and is most commonly found as flash
chips on tapes.
This includes support for reading attributes and decoding most
known attributes, but does not yet include support for writing
attributes or reporting attributes in XML format.
libsbuf/Makefile:
Add subr_prf.c for the new sbuf_hexdump() function. This
function is essentially the same function.
libsbuf/Symbol.map:
Add a new shared library minor version, and include the
sbuf_hexdump() function.
libsbuf/Version.def:
Add version 1.4 of the libsbuf library.
libutil/hexdump.3:
Document sbuf_hexdump() alongside hexdump(3), since it is
essentially the same function.
camcontrol/Makefile:
Add attrib.c.
camcontrol/attrib.c:
Implementation of READ ATTRIBUTE support for camcontrol(8).
camcontrol/camcontrol.8:
Document the new 'camcontrol attrib' subcommand.
camcontrol/camcontrol.c:
Add the new 'camcontrol attrib' subcommand.
camcontrol/camcontrol.h:
Add a function prototype for scsiattrib().
share/man/man9/sbuf.9:
Document the existence of sbuf_hexdump() and point users to
the hexdump(3) man page for more details.
sys/cam/scsi/scsi_all.c:
Add a table of known attributes, text descriptions and
handler functions.
Add a new scsi_attrib_sbuf() function along with a number
of other related functions that help decode attributes.
scsi_attrib_ascii_sbuf() decodes ASCII format attributes.
scsi_attrib_int_sbuf() decodes binary format attributes, and
will pass them off to scsi_attrib_hexdump_sbuf() if they're
bigger than 8 bytes.
scsi_attrib_vendser_sbuf() decodes the vendor and drive
serial number attribute.
scsi_attrib_volcoh_sbuf() decodes the Volume Coherency
Information attribute that LTFS writes out.
sys/cam/scsi/scsi_all.h:
Add a number of attribute-related structure definitions and
other defines.
Add function prototypes for all of the functions added in
scsi_all.c.
sys/kern/subr_prf.c:
Add a new function, sbuf_hexdump(). This is the same as
the existing hexdump(9) function, except that it puts the
result in an sbuf.
This also changes subr_prf.c so that it can be compiled in
userland for includsion in libsbuf.
We should work to change this so that the kernel hexdump
implementation is a wrapper around sbuf_hexdump() with a
statically allocated sbuf with a drain. That will require
a drain function that goes to the kernel printf() buffer
that can take a non-NUL terminated string as input.
That is because an sbuf isn't NUL-terminated until it is
finished, and we don't want to finish it while we're still
using it.
We should also work to consolidate the userland hexdump and
kernel hexdump implemenatations, which are currently
separate. This would also mean making applications that
currently link in libutil link in libsbuf.
sys/sys/sbuf.h:
Add the prototype for sbuf_hexdump(), and add another copy
of the hexdump flag values if they aren't already defined.
Ideally the flags should be defined in one place but the
implemenation makes it difficult to do properly. (See
above.)

Clear p_stops when doing PT_DETACH and PROCFS_CTL_DETACH.
Without this, if a process was being traced by truss(1), which
uses different p_stops bits than gdb(1), the latter would
misbehave because of the unexpected bits.

Rework vtblk dump handling of in flight requests
Previously, the driver resets the device and abandon the requests that
are caught in flight when the dump was initiated. This was problematic
if the system is resumed after the dump is completed.
While that is probably not the typical action, it is simple to rework
the driver to very likely have the device usable after the dump without
making it more likely for the dump to fail. The in flight requests are
simply queued for completion once the dump is finished.
r282533 : Corrected indentation on conflicted source files.
r282532 : Configured the mrsas(4) driver to support UNMAPPED I/O and updated driver version.
r282531 :
1. All LSI namings are converted to AVAGO Tech.
2. Fix in AEN path(suggested by John Baldwin).
3. Fix IOCTL path w.r.t Sense key handling
r282530 :
Bug fixes found internally as detailed below:
1. While disabling interrupt the FW disables interrupts for only 16 vectors.
In case of Invader which supports 96 MSI-x vectors, some spurious interrupts
may come on other vectors even after interrupt disable. So, driver uses a flag
and ignores the spurious interrupts.
2. Reply queue depth is made double the number of commands supported by FW.
3. Misplaced interrupt enable code is now moved down in the OCR path.
4. Updated error handling code in OCR path.
5. Removed un-necessary print.
r282529 :
Driver calls mrsas_complete_cmd() to call mrsas_wakeup() for each MFI frame that was
issued through the ioctl() interface prior to the kill adapter. This ensures
userspace ioctl() system calls issued just before a kill adapter don't get stuck in
wait state and IOCTLs are returned to application.
r282528 :
In OCR(Online Controller Reset) path, driver sets adapter state to
MEGASAS_HBA_OPERATIONAL before getting new RAID map.
There will be a small window where IO will come from OS with old RAID map.
This patch will update adapter state to MEGASAS_HBA_OPERATIONAL,
only after driver has new RAID map to avoid any IOs getting build using old RAID map.
r282527 :
Current driver does fast path read load balancing between arm and mirror disk
for two Drive Raid-1 configuration only.
Now, Driver support fast path read load balancing for all (any number of disk) Raid-1 configuration.
r282526 :
Now Driver expose Secure Jbod Support via driver_operations in MFI INIT Frame.
FW expose Secure Jbod support via Controller properity.
Firmware expect IOs to be received from different IO path than
conventional fast path queue, in case of SED drives.
To have Secure jbod support user need driver and firmware support.
r282525 : This patch adds the feature to provide PCI information via IOCTL query.
Fix a callout race condition introduced in TCP timers callouts with r281599.
In TCP timer context, it is not enough to check callout_stop() return value
to decide if a callout is still running or not, previous callout_reset()
return values have also to be checked.
Make the size of the hash tables used by the NFSv4 server tunable.
No appreciable change in performance was observed after increasing
the sizes of these tables and then testing with a single client.
However, there was an email that indicated high CPU overheads for
a heavily loaded NFSv4 and it is hoped that increasing the sizes
of the hash tables via these tunables might help.
The tables remain the same size by default.
Prevent dounmount() from acting on the freed (although type-stable)
memory by changing the interface to require the mount point to be
referenced.
MFC r283629:
Add missed {}.
Perform SU cleanup in the AST handler. Do not sleep waiting for SU cleanup
while owning vnode lock.
On MFC, for KBI stability, td_su member was moved to the end of the
struct thread.
Properly null-terminate strings in a kernel dump header. A version string
longer than 192 bytes will cause the version field of a dump header to
overflow. strncpy doesn't null terminate it, so savecore will print a
corrupted info file. Using strlcpy fixes the bug.
Remove unneeded NULL checks in amd64's trap_fatal().
Since td_name is an array member of struct thread, it can never be NULL,
so the check can be removed. In addition, curproc can never be NULL,
so remove the if statement, and splice the two printfs() together.
While here, remove the u_long cast, and use the correct printf format
specifier curproc->p_pid.

The NFS client generated directory block(s) with d_fileno == 0
so that it would not return less data than requested.
Since returning less directory data than requested is not a problem
for FreeBSD and even UFS no longer returns directory structures
with d_fileno == 0, this patch stops the client from doing this.
Although entries with d_fileno == 0 should not be a problem,
the man pages no longer document that these entries should be
ignored, so there was a concern that these entries might be an
issue in the future.
Place VM objects on the object list when created and never remove them.
261811:
Fix function name in KASSERT().
282660:
Place VM objects on the object list when created and never remove them.
This is ok since objects come from a NOFREE zone and allows objects to
be locked while traversing the object list without triggering a LOR.
Ensure that objects on the list are marked DEAD while free or stillborn,
and that they have a refcount of zero. This required updating most of
the pagers to explicitly mark an object as dead when deallocating it.
(Only the vnode pager did this previously.)

Satisfy vm_object uma zone destructor requirements after r282660 when
vnode object creation raced.

Track the per-adapter activation of ULDs in a new "active_ulds" field.
This was done pretty arbitrarily before this change -- via TOM_INIT_DONE
in adapter->flags for TOM, and the (1 << MAX_NPORTS) bit in
adapter->offload_map for iWARP.
iWARP and hw-accelerated iSCSI rely on the TOE (supported by the TOM
ULD). The rules are:
a) If the iWARP and/or iSCSI ULDs are available when TOE is enabled then
iWARP and/or iSCSI are enabled too.
b) When the iWARP and iSCSI modules are loaded they go looking for
adapters with TOE enabled and enable themselves on that adapter.
c) You cannot deactivate or unload the TOM module from underneath iWARP
or iSCSI. Any such attempt will fail with EBUSY.
