error = dmu_sync(zio, lr->lr_common.lrc_txg,
zfs_get_done, zgd);
ASSERT(error || lr->lr_length <= zp->z_blksz);
It's possible, although extremely rare, that the zfs_get_done() callback is
executed before dmu_sync() returns.
In that case the znode's range lock is dropped and the znode is unreferenced.
Thus, the assertion can access some invalid or wrong data via the zp pointer.
size variable caches the correct value of z_blksz and can be safely used here.

In FreeBSD we only use mdoc(7) format. A template is available as mdoc.template
The usage of man(7) format is discouraged and this file was driving people into
the front direction as a template to use.
Since the translation to vt as terminal emulator, the keymaps files
path has changed and this change does not get followed in bsdconfig.
This implicates boot time warnings about a wrong keymap file, what
is very confusing for the new users and for me too, so initialize
the default keymaps search path depending on terminal type.

DELAY is a problematic routine called all over the kernel.
Armada38x using CA-9 CPUs are using mpcore timer to count events
and measure time but DELAY in the mpcore timer code is a weak
function reference and therefore will be replaced by the platform
implementation if the one is introduced. Since Armada38x uses
on-chip watchdog to which the driver is merged with the on-chip timer
driver there will be a platform DELAY implementation.
The latter however will not use any HW timers as it will not attempt
to configure any. Phony busy loop will be used instead.
To fix that we introduce a separate watchdog driver for Armada platforms,
(currently only A38X) and stop using Marvell timer driver. That
switches DELAY to the desired implementation.

- there has been a failure to allocate an mbuf for the packet and
the packet has to be dropped

In the deep past, when this code compiled as a binary module, ath_hal
built as a module. This allowed custom, smaller HAL modules to be built.
This was especially beneficial for small embedded platforms where you
didn't require /everything/ just to run.
However, sometime around the HAL opening fanfare, the HAL landed here
as one big driver+HAL thing, and a lot of the (dirty) infrastructure
(ie, #ifdef AH_SUPPORT_XXX) to build specific subsets of the HAL went away.
This was retained in sys/conf/files as "ath_hal_XXX" but it wasn't
really floated up to the modules themselves.
I'm now in a position where for the reaaaaaly embedded boards (both the
really old and the last couple generation of QCA MIPS boards) having a
cut down HAL module and driver loaded at runtime is /actually/ beneficial.
This reduces the kernel size down by quite a bit. The MIPS modules look
like this:
adrian@gertrude:~/work/freebsd/head-embedded/src % ls -l ../root/mips_ap/boot/kernel.CARAMBOLA2/ath*ko
-r-xr-xr-x 1 adrian adrian 5076 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_dfs.ko
-r-xr-xr-x 1 adrian adrian 100588 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_hal.ko

-r-xr-xr-x 1 adrian adrian 23472 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_rate.ko
And the x86 versions, like this:
root@gertrude:/home/adrian # ls -l /boot/kernel/ath*ko
-r-xr-xr-x 1 root wheel 36632 May 24 18:32 /boot/kernel/ath_dfs.ko

.. so you can see, not building the whole HAL can save quite a bit.
For example, if you don't need AR9300 support, you can actually avoid
wasting half a megabyte of RAM. On embedded routers this is quite a
big deal.
The AR9300 HAL can be later further shrunk because, hilariously,
it indeed supports AH_SUPPORT_<xxx> for optionally adding chipset support.
(I'll chase that down later as it's quite a big savings if you're only
building for a single embedded target.)
So:
* Create a very hackish way to load/unload HAL modules
* Create module metadata for each HAL subtype - ah_osdep_arXXXX.c
* Create module metadata for ath_rate and ath_dfs (bluetooth is
currently just built as part of it)
* .. yes, this means we could actually build multiple rate control
modules and pick one at load time, but I'd rather just glue this
into net80211's rate control code. Oh well, baby steps.
* Main driver is now "ath_main"
* Create an "if_ath" module that does what the ye olde one did -
load PCI glue, main driver, HAL and all child modules.
In this way, if you have "if_ath_load=YES" in /boot/modules.conf
it will load everything the old way and stuff should still work.
* For module autoloading purposes, I actually /did/ fix up
the name of the modules in if_ath_pci and if_ath_ahb.
If you want to selectively load things (eg on ye cheape ARM/MIPS platforms
where RAM is at a premium) you should:
* load ath_hal
* load the chip modules in question
* load ath_rate, ath_dfs
* load ath_main
* load if_ath_pci and/or if_ath_ahb depending upon your particular
bus bind type - this is where probe/attach is done.
TODO:
* AR5312 module and associated pieces - yes, we have the SoC side support
now so the wifi support would be good to "round things out";
* Just nuke AH_SUPPORT_AR5416 for now and always bloat the packet
structures; this'll simplify other things.
* Should add a simple refcnt thing to the HAL RF/chip modules so you
can't unload them whilst you're using them.
* Manpage updates, UPDATING if appropriate, etc.

lzc_create(), or more correctly, zfs_ioc_create() does not reject an attempt to
create a filesystem as a child of a volume, instead it proceeds to a crash.
A crash stack obtained on FreeBSD:
page fault while in kernel mode
zap_leaf_lookup()
fzap_lookup()
zap_lookup_norm()
zap_lookup()
zfs_get_zplprop()
zfs_fill_zplprops_impl()
zfs_ioc_create()
zfsdev_ioctl()
devfs_ioctl_f()
kern_ioctl()
sys_ioctl()
This crash happened with a kernel without debugging assertions.
The immediate cause of crash appears to an attempt to interpret a zvol object
as a zap object.
For filesystems:
#define MASTER_NODE_OBJ 1
For zvols:
#define ZVOL_OBJ 1ULL
#define ZVOL_ZAP_OBJ 2ULL
So, I see two problems here:
1. an attempt to create a filesystem under a zvol should be rejected as
early as possible, maybe in zfs_fill_zplprops()
2. maybe zap_lookup / zap_lockdir should reject objects that are not of one
of the zap object types
