The faulting instruction needs to be restarted when the exception handler
is done handling the fault. bhyve now does this correctly by setting
'vmexit[vcpu].inst_length' to zero so the %rip is not advanced.
A minor complication is that the fault injection APIs are used by instruction
emulation code that is shared by vmm.ko and bhyve. Thus the argument that
refers to 'struct vm *' in kernel or 'struct vmctx *' in userspace needs to
be loosely typed as a 'void *'.

a list of packages using the bsdconfig(8) API, providing dialog(8) based
user experience (versus plain console output were you to use pkg(8)
directly to install the same list of packages).
Remove example script `browse_packages_ftp.sh', made obsolete because
the digests.txz and packagesite.txz databases for pkg(8) are not
available via FTP (HTTP only to pkg.freebsd.org SRV hosts).
Update example script `browse_packages_http.sh', made to work with new
pkg(8) demonstrating how to generate a local package repository.
Fix a bug in `bsdconfig packages' where packages were listed twice. This
fix requires pkg(8) version 1.2.7_4 or higher.
NB: It is the introduction of pkg(8) 1.2.7_4 wherein I am also able to
drastically reduce the generation time of package dependencies prior to
the dialog display (by utilizing the new `-I' flag to pkg-rquery(8)).
While here, fix a positional argument nit for f_index_initialize() of
`packages/index.subr' include (the one and only argument is positional
argument 1 to state the by-ref handle, indicating the variable to set
in the caller's namespace; the nit I'm fixing here is that we were
querying positional argument 2 for this information incorrectly; caused
by a missing hunk back around SVN r257795).
Fix a bug in sysrc(8) described by PR bin/187458 "sysrc(8) silently and
unexpectedly bootstraps pkg". This was caused by an explicit entry in
`/usr/share/bsdconfig/common.subr' (used by sysrc(8)) that called pkg(8)
to populate the $PKG_ABI global (called in a way that allows implicit
bootstrap of pkg(8)). The solution to which was to find every place in
bsdconfig(8) that requires the $PKG_ABI global and add a layer of
protection by way of introducing the new API call f_musthavepkg_init()
(provided by new include, `/usr/share/bsdconfig/packages/musthavepkg.subr'
intented to mirror `/usr/share/bsdconfig/mustberoot.subr'). When the
$PKG_ABI global is required, you can use `f_musthavepkg_init' to cause
graceful premature termination in the event that pkg(8) has not yet been
bootstrapped, and thus cannot be used to populate $PKG_ABI.
NB: If running interactively ($nonInteractive is NULL or unset), the
f_musthavepkg_init() API call will attempt to bootstrap pkg(8), but only
if the user chooses "Yes" to a Yes/No dialog confirming it is ok to
bootstrap.
While here, simplify an if-conditional in `media/http.subr' include to
use sh(1) inline assignment-with-break.
Also, fix a bug in `media/http.subr' and `media/httpproxy.subr' wherein
the error messages for various HTTP failures were not finding their way
to the console (needed to pass stdout to pass-thru descriptor).
While here, remove the executable bit from `packages/categories.subr',
`packages/index.subr', and `packages/packages.subr' includes.
Fix issues where pkg(8) complains about PACKAGESITE being defined.
Previously, we would set $PACKAGESITE and export it. Now we only set
$PACKAGESITE for invocations of "pkg update" -- getting rid of all the
spurious warnings about PACKAGESITE being deprecated (it's still used
in the case of "pkg update" for simplicity versus having to configure
a config-file).
Remove the leading argument from invocations of f_index_initialize() in
`packages/packages.subr' include. The leading argument no longer means
what it used to, pre SVN r257995).

A nested exception condition arises when a second exception is triggered while
delivering the first exception. Most nested exceptions can be handled serially
but some are converted into a double fault. If an exception is generated during
delivery of a double fault then the virtual machine shuts down as a result of
a triple fault.
vm_exit_intinfo() is used to record that a VM-exit happened while an event was
being delivered through the IDT. If an exception is triggered while handling
the VM-exit it will be treated like a nested exception.
vm_entry_intinfo() is used by processor-specific code to get the event to be
injected into the guest on the next VM-entry. This function is responsible for
deciding the disposition of nested exceptions.

For LUNs without these IDs VMWare will use traditional copy operations.
Beware: the above LUN IDs explicitly set to values non-unique from the VM

Instead make ports provide wanted port and target IDs, and LUNs provide
wanted LUN IDs. After that core Device ID VPD code only had to link all
of them together and add relative port and port group numbers.
LUN ID for iSCSI LUNs no longer created by CTL, but by ctld, and passed
to CTL as "scsiname" LUN option. This makes LUNs to report the same set
of IDs, independently from the port through which it is accessed, as
required by SCSI specifications.
Having single port for all iSCSI connections makes problematic implementing
some more advanced SCSI functionality in CTL, that require proper ports
enumeration and identification.
This change extends CTL iSCSI API, making ctld daemon to control list of
iSCSI ports in CTL. When new target is defined in config fine, ctld will
create respective port in CTL. When target is removed -- port will be
also removed after all active commands through that port properly aborted.
This change require ctld to be rebuilt to match the kernel.
As a minor side effect, this allows to have iSCSI targets without LUNs.
While that may look odd and not very useful, that is not incorrect.

This changes the installer to use the correct names, which also breaks a

Previously the sizes were inferred indirectly based on the size of the mappings
at 0 and 4GB respectively. This works fine as long as size of the allocation is
identical to the size of the mapping in the guest's address space. However, if
the mapping is disjoint then this assumption falls apart (e.g., due to the
legacy BIOS hole between 640KB and 1MB).
