Fix a segfault in ctfmerge(1) due to a bug in GCC.

The change was correct and the bug real, but upstream didn't adopt it
and we want to remain in sync. When/if upstream does something about it
we can bring their version.

The bug in question was fixed in GCC 4.9 which is now the default in
FreeBSD's ports. Our native gcc-4.2, which is still in use in some Tier-2
platforms also has a workaround so no end-user should be harmed by the
revert.

dd is currently a bootstrap tool. It really doesn't have any business
being a bootstrap tool. However, for reproducible build output,
FreeBSD added dd status=none because it was otherwise difficult to
suppress the status information, but retain any errors that might
happen. There's no real reason that dd has to be a build tool, other
than we use status=none unconditional. Remove dd from a bootstrap tool
entirely by only using status=none when available. This may also help
efforts to build the system on non-FreeBSD hosts as well.

Retire long-broken/unused static rtld support

rtld-elf has some vestigial support for building as a static executable.
r45501 introduced a partial implementation with a prescient note that it
"might never be enabled." r153515 introduced ELF symbol versioning
support, and removed part of the unused build infrastructure for static
rtld.

GNU ld populates rela relocation addends and GOT entries with the same
values, and rtld's run-time dynamic executable check relied on this.
Alternate toolchains may not populate the GOT entries, which caused
RTLD_IS_DYNAMIC to return false. Simplify rtld by just removing the
unused check.

If we want to restore static rtld support later on we ought to introduce
a build-time #ifdef flag.

Allow a user-overridable setting 'PKG_CMD' to control the command used

This would have been useful for a situation I found myself in where
pkg(8) had been upgraded to a version that wanted the FBSD_1.5 ABI
version but libc.so.7 had not been upgraded, and only provided
FBSD_1.4. I found I needed to update libc in order to run pkg, and I
also needed to use pkg to update libc... Which is why pkg-static
exists, but there's currently no way to tell the build system to use
pkg-static instead of pkg.

This creates a variable PKG_CMD, default value 'pkg', that can be

bhyve: stability and performance improvement for dbgport

The TCP server implementation in dbgport does not track clients, so it
may try to write to a disconected socket resulting in SIGPIPE.
Avoid that by setting SO_NOSIGPIPE socket option.

Because dbgport emulates an I/O port to guest, the communication is done
byte by byte. Reduce latency of the TCP/IP transfers by using
TCP_NODELAY option. In my tests that change improves performance of
kgdb commands with lots of output (e.g. info threads) by two orders of
magnitude.

A general note. Since we have a uart emulation in bhyve, that can be
used for the console and gdb access to guests. So, bvmconsole and bvmdebug
could be de-orbited now. But there are many existing deployments that
still dependend on those.

Problem statement:
MFI linked list in megaraid_sas driver is used for mfi-mpt pass-through commands.
This list can be corrupted due to many possible race conditions in driver and
eventually we may see kernel panic.

One example -
MFI frame is freed from calling process as driver send command via polling method and interrupt
for that command comes after driver free mfi frame (actually even after some other context reuse
the mfi frame). When driver receive MPT frame in ISR, driver will be using the index of MFI and
access that MFI frame and finally in-used MFI frames list will be corrupted.

High level description of new solution -
Free MFI and MPT command from same context.
Free both the command either from process (from where mfi-mpt pass-through was called) or from
ISR context. Do not split freeing of MFI and MPT, because it creates the race condition which
will do MFI/MPT list.

Fix interrupt clear in pl011 uart receive function

Clear the interrupt state before reading the input char from the
input FIFO. In the current code there is a window between the read
to the data register and the write to the the ICR, during which an
input char will not cause an interrupt.

This fixes the issue by which the serial port input on QEMU freezes

[ath] force wake the hardware if we see a missed beacon.

This adds a workaround to incorrectly behaving APs (ie, FreeBSD APs) which
don't beacon out exactly when they should (at TBTT multiples of beacon
intervals.)

It forces the hardware awake (but leaves it in network-sleep so self
generated frames still state that the hardware is asleep!) and will
remain awake until the next sleep transition driven by net80211.

That way if the beacons are just at the wrong interval, we get a much
better chance of hearing more consecutive beacons before we go to sleep,
thus not constantly disconnecting.

Tested:

* AR9485, STA mode, against a misbehaving FreeBSD AP.

So:

* fix the FreeBSD APs that are sending beacons at incorrect TBTTs (target
beacon transmit time); and
* yes indeed we will have to wake up out of network sleep until we sync
a beacon.

MFV r309249: 3821 Race in rollback, zil close, and zil flush

Note: there was a merge conflict resolved by me.

illumos/illumos-gate@43297f973a3543e7403ac27076490ab958a94b15
https://github.com/illumos/illumos-gate/commit/43297f973a3543e7403ac27076490ab958a94b15

https://www.illumos.org/issues/3821
We recently had nodes with some of the latest zfs bits panic on us in a
rollback-heavy environment. The following is from my preliminary analysis:
Let's look at where we died:
> $C
ffffff01ea6b9a10 taskq_dispatch+0x3a(0, fffffffff7d20450, ffffff5551dea920, 1)
ffffff01ea6b9a60 zil_clean+0xce(ffffff4b7106c080, 7e0f1)
ffffff01ea6b9aa0 dsl_pool_sync_done+0x47(ffffff4313065680, 7e0f1)
ffffff01ea6b9b70 spa_sync+0x55f(ffffff4310c1d040, 7e0f1)
ffffff01ea6b9c20 txg_sync_thread+0x20f(ffffff4313065680)
ffffff01ea6b9c30 thread_start+8()
If we dig in we can find that this dataset corresponds to a zone:
> ffffff4b7106c080::print zilog_t zl_os->os_dsl_dataset->ds_dir->dd_myname
zl_os->os_dsl_dataset->ds_dir->dd_myname = [ "8ffce16a-13c2-4efa-a233-
9e378e89877b" ]
Okay so we have a null taskq pointer. That only happens during the calls to
zil_open and zil_close. If we poke around we can see that we're actually in
midst of a rollback:
> ::pgrep zfs | ::printf "0x%x %s\\n" proc_t . p_user.u_psargs

[ath] wake up the hardware from power-save before doing transmit completion checking.

This was being done in the pre-AR9380 case, but not for AR9380 and later.
When powersave in STA mode is enabled, this may have lead to the transmit
completion code doing this:

* call the task, which doesn't wake up the hardware
* complete the frames, which doesn't touch the hardware
* schedule pending frames on the hardware queue, which DOES touch the
hardware, and this will be ignored

This would show up in the logs like this:

(with debugging enabled):
Nov 27 23:03:56 lovelace kernel: Q1[ 0] (nseg=1) (DS.V:0xfffffe011bd57300 DS.P:0x49b57300) I: 168cc117 L:00000000 F:0005

(in general, doesn't require debugging enabled):
Nov 27 23:03:56 lovelace kernel: ath_hal_reg_write: reg=0x00000804, val=0x49b57300, pm=2

That register is a EDMA TX FIFO register (queue 1), and the val is the descriptor
being written.

Whilst here, make sure the software queue gets kicked here.

[ath] fix target beacon interval programming for STA mode when in powersave.

This bug has been bugging me for quite some time. I finally sat down
with enough coffee to figure it out.

The short of it - rounding up to the next intval multiple of the TSF value
only works if the AP is transmitting all its beacons on an interval of
the TSF. If it isn't - for example, doing staggered beacons on a multi-VAP
setup with a single hardware TSF - then weird things occur.

The long of it -

When powersave is enabled, the MAC and PHY are partially powered off.
They can't receive any packets (or transmit, for that matter.)
The target beacon timer programming will wake up the MAC/PHY just before
the beacon is supposed to be received (well, strictly speaking, at DTIM
so it can see the TIM - traffic information map - telling the STA whether
any traffic is there for it) and it happens automatically.

However, this relies on the target beacon time being programmed correctly.
If it isn't then the hardware will wake up and not hear any beacons -
and then it'll be asleep for said beacons. After enough of this, net80211
will give up and assume the AP went away.

This should fix both TSFOOR interrupts and disconnects from APs with powersave
enabled.

The annoying bit is that it only happens if APs stagger things or start
on a non-zero TSF. So, this would sometimes be fine and sometimes not be
fine.

What:

* I don't know (yet) why the code rounds up to the next intval.
For now, just disable rounding it and trust the value we get.

TODO:

* If we do see a beacon miss in STA mode then we should transition
out of sleep for a while so we can hear beacons to resync against.
I'd love a patch from someone to enable that particular behaviour.
Note - that doesn't require that net80211 brings the chip out of
sleep state - only that we wake the chip up through to full-on and
then let it go to sleep again when we've seen a beacon. The wifi
stack and AP can still completely just stay believing we're in sleep
mode.

* AR9485, STA mode, powersave enabled

bhnd(4): Unify NVRAM/SPROM parsing, implement compact SPROM layout encoding.

- Defined an abstract NVRAM I/O API (bhnd_nvram_io), decoupling NVRAM/SPROM
parsing from the actual underlying NVRAM data provider (e.g. CFE firmware
devices).
- Defined an abstract NVRAM data API (bhnd_nvram_data), decoupling
higher-level NVRAM operations (indexed lookup, data conversion, etc) from
the underlying NVRAM file format parsing/serialization.
- Implemented a new high-level bhnd_nvram_store API, providing indexed
variable lookup, pending write tracking, etc on top of an arbitrary
bhnd_nvram_data instance.
- Migrated all bhnd(4) NVRAM device drivers to the common bhnd_nvram_store
API.
- Implemented a common bhnd_nvram_val API for parsing/encoding NVRAM
variable values, including applying format-specific behavior when
converting to/from the NVRAM string representations.
- Dropped the now unnecessary bhnd_nvram driver, and moved the
broadcom/mips-specific CFE NVRAM driver out into sys/mips/broadcom.
- Implemented a new nvram_map file format:
- Variable definitions are now defined separately from the SPROM
layout. This will also allow us to define CIS tuple NVRAM
mappings referencing the common NVRAM variable definitions.
- Variables can now be defined within arbitrary named groups.
- Textual descriptions and help information can be defined inline
for both variables and variable groups.
- Implemented a new, compact encoding of SPROM image layout
offsets.
- Source-level (but not build system) support for building the NVRAM file
format APIs (bhnd_nvram_io, bhnd_nvram_data, bhnd_nvram_store) as a
userspace library.

The new compact SPROM image layout encoding is loosely modeled on Apple
dyld compressed LINKEDIT symbol binding opcodes; it provides a compact
state-machine encoding of the mapping between NVRAM variables and the SPROM
image offset, mask, and shift instructions necessary to decode or encode
the SPROM variable data.

The compact encoding reduces the size of the generated SPROM layout data
from roughly 60KB to 3KB. The sequential nature SPROM layout opcode tables
also simplify iteration of the SPROM variables, as it's no longer
neccessary to iterate the full NVRAM variable definition table, but
instead simply scan the SPROM revision's layout opcode table.

Launder VPO_NOSYNC pages upon vnode deactivation.

As of r234483, vnode deactivation causes non-VPO_NOSYNC pages to be
laundered. This behaviour has two problems:

1. Dirty VPO_NOSYNC pages must be laundered before the vnode can be
reclaimed, and this work may be unfairly deferred to the vnlru process
or an unrelated application when the system is under vnode pressure.
2. Deactivation of a vnode with dirty VPO_NOSYNC pages requires a scan of
the corresponding VM object's memq for non-VPO_NOSYNC dirty pages; if
the laundry thread needs to launder pages from an unreferenced such
vnode, it will reactivate and deactivate the vnode with each laundering,
potentially resulting in a large number of expensive scans.

Therefore, ensure that all dirty pages are laundered upon deactivation,
i.e., when all maps of the vnode are removed and all references are
released.

If machine has ncpus >= 8 and non-FSB interrupt routing from HPET,

350. On the other hand, LAPIC default quality is 600 and it is reduced
by 200 if ARAT is not reported. We end up with HPET quality 350 <
LAPIC quality 400, despite ARAT is not set. Then, since deep Cx
states are active by default, eventtimer fail.

E.g., on Nehalem Core i7 CPU and X58 chipset, LAPIC only works in
C0/C1/C1E and HPET does not implement FSB mode, which otherwise
requires manual switch to HPET to get working system.

Set LAPIC eventtimer quality to 100 if no ARAT.
While there, do not ignore deadlint TSC mode for LAPIC timer if ARAT

Use explicit 0x200000 instead of MAXPAGESIZE for the amd64 kernel physaddr

MAXPAGESIZE is not well defined by the GNU ld documentation.
Different linkers, and different versions of the same linker, use
different MAXPAGESIZE values. Current versions of GNU gold and LLVM's
lld use 4K. When set to 4K the kernel panics at boot due to an issue
with x86bios.

Here we want the kernel physaddr to be the amd64 superpage size, so use
that value (2MB) explicitly. With this change GNU gold and LLVM lld can
link a working amd64 kernel.

Pull in r283060 from upstream llvm trunk (by Hal Finkel):

[PowerPC] Refactor soft-float support, and enable PPC64 soft float

This change enables soft-float for PowerPC64, and also makes
soft-float disable all vector instruction sets for both 32-bit and
64-bit modes. This latter part is necessary because the PPC backend
canonicalizes many Altivec vector types to floating-point types, and
so soft-float breaks scalarization support for many operations. Both
for embedded targets and for operating-system kernels desiring
soft-float support, it seems reasonable that disabling hardware
floating-point also disables vector instructions (embedded targets
without hardware floating point support are unlikely to have Altivec,
etc. and operating system kernels desiring not to use floating-point
registers to lower syscall cost are unlikely to want to use vector
registers either). If someone needs this to work, we'll need to
change the fact that we promote many Altivec operations to act on
v4f32. To make it possible to disable Altivec when soft-float is
enabled, hardware floating-point support needs to be expressed as a
positive feature, like the others, and not a negative feature,
because target features cannot have dependencies on the disabling of
some other feature. So +soft-float has now become -hard-float.

Fixes PR26970.

Pull in r283061 from upstream clang trunk (by Hal Finkel):

[PowerPC] Enable soft-float for PPC64, and +soft-float -> -hard-float

the target features accordingly.

Permit timed sleeps for threads other than thread0 before timers are working.

The callout subsystem already handles early callouts and schedules
the first clock interrupt appropriately based on the currently pending
callouts. The one nit to fix was that callouts scheduled via C_HARDCLOCK
during early boot could fire too early once timers were enabled as the
per-CPU base time is always zero until timers are initialized. The change
in callout_when() handles this case by using the current uptime as the
base time of the callout during bootup if the per-CPU base time is zero.

It allows one to trivially convert an absolute path to a relative path

These are sometimes known as the --relative and --absolute flags and
can force a symlink to be relative when you only have an absolue path.
Another place these are sometimes used is to add -a and -r args to 'realpath'.
Incredibly useful in Makefiles.

[net80211] flesh out more IBSS 11n support

* Pepper comments around which describe what state(s) we're in when faking
up 11n nodes.
* By default don't fake it up as 11n until we properly negotiate the 11n
capabilities using probe request/response frames.
* Send a probe request with our HT information, as the 802.11-2012 spec
suggests.
* Reassociate with the driver if we've been promoted.

This is done because although learning a peer via beacons can learn 11n
state, learning peers via hearing probe frames and broadcast frames
does not. Thus, sometimes you end up with an 11n peer in the peer
table and sometimes you don't.

Note that the probe request/response exchange may not actually succeed.
Ideally we'd put the peer into some blocking state until we've exchanged
probe request/reponse to learn capabilities, or we timeout and just
stay non-11n.

This is more an experiment to get 11n IBSS nodes actually discovering
each other and be able to transmit. There are other issues that creep
up which I'll attempt to address in future commits.

Fix error reporting from wcstof()

When wcstof() skipped initial space and then parsing failed, it set
endptr to the first non-space character. Fix it to correctly report
failure by setting endptr to the beginning of the input string.
The fix is from theraven@, who fixed this bug in wcstod() and
wcstold() in r227753.

While I'm here:

Move assignments out of declarations in wcstod() and wcstold().
This is against my personal preference, but it is our agreed style(9).

Set endptr correctly on malloc() failure in all three functions.

Remove an incorrect comment: This is pointer arithmetic,
so the code was not actually making that assumption.

wcstold() advanced the wcp pointer beyond leading whitespace
and then reset it back to the beginning of the string.
Do not reset it. This seems to have no functional effect,
since strtold_l() also skips leading whitespace. I'm making
the change to keep this function consistent with wcstof() and
wcstod(), and because the C11 spec prescribes the use of iswspace()
to skip leading space.

Fix buildworld for powerpc.

vmpage requires struct pmap to exist and contain a pm_stats field. As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs. Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct. This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.

Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.

Modify umount so that it does not do an Unmount RPC for NFSv4 mounts
and uses TCP for the Unmount RPC if the mount is over TCP.
Without this patch, umount does an Unmount RPC over UDP for all NFS mounts.

i386 turns out to not have __uint128_t. So confusingly use 64-bit math
instead. Since we're little endian, we can get away with it. Also,
since the counters in quesitons would require billions of iops for
tens of billions of seconds to overflow, and since such data rates are
unlikely for people using i386 for a while, that's OK. The fastest
cards today can't do even a million IOPs.

[dd] Revert the capsicum bits for now until it gets fixed.

dd is a bootstrap tool and that header isn't installed as part of the
bootstrap environment for previous releases (eg freebsd-10.)

We'll figure it out in post and then re-commit it.

Decode the Intel-specific Additional SMART data page (0xca) and print
it in human readable form. Include a pointer to the public spec that
was followed to implement this in the code. Samsung also implements
page 0xca on some of their drives, but the format is slighly
different, so the code skips printing zero keys. Samsung's log page
has additional, unknown data after the end of Intel defined data which
isn't displayed.
