Rework the way we enable CTL iSCSI port. Previously conf_apply()
needed it to be already enabled, because listening in proxy mode
requires it; however, it's conf_apply() that opens pidfiles,
so it resulted in port being enabled before pidfile was opened.
This was not so bad, but it was also disabled when pidfile couldn't
be opened due to ctld already running; this means that starting
second ctld instance screwed up the first.
Make it possible for the iSCSI target side to operate in both normal
and ICL_KERNEL_PROXY mode, and fix some bit rot so the latter actually
works again.
Backout r257223,r257224,r257225,r257246,r257710. The changes caused
some regressions in ICMP handling, and right now me and Baptiste
are out of time on analyzing them.
Vlan did not set the value of if_hw_tsomax, so when vlan
was stacked on top of a network interface that set if_hw_tsomax,
tcp_output() would see the default value instead of the value
set by the network interface. This patch modifies vlan so that
it sets if_hw_tsomax to the value of the parent interface.
Don't spindown the BSP if it executes hlt with the APIC disabled. A
guest that doesn't use the APIC at all can trigger this, plus the BSP
always needs to execute as it should trigger a reset, etc.
Local APIC access via 32-bit naturally-aligned loads is merely
suggested in the SDM. Since some OSes have implemented otherwise
don't be too rigorous in enforcing it.
Make sure not to do I/O for more than MAXPHYS bytes. Doing so can cause
problems in our providers, such as a KASSERT in md(4). We can initiate
I/O for more than MAXPHYS bytes if we've been given a BIO for MAXPHYS
bytes, the blocks from which we're reading couldn't be compressed and
we had compression in preceeding blocks resulting in misalignment of
the blocks we're trying to read relative to the sector. We're forced to
round up the I/O length to make it an multiple of the sector size.
When we detect the condition, we'll reduce the block count and perform
a "short" read. In g_uzip_done() we need to consider the original I/O
length and stop early if we're about to deflate a block that we didn't
read. By using bio_completed in the cloned BIO and not bio_length to
check for this, we automatically and gracefully handle short reads that
our providers may be doing on top of the short reads we may initiate
ourselves.
Use SMB_QUERY_FS_SIZE_INFO request to populate statfs structure.
When server doesn't support this request, try to use SMB_INFO_ALLOCATION.
And use SMB_COM_QUERY_INFORMATION_DISK request as fallback.
When merging docsinstall and zfsboot updates to stable/9 it was discovered
that the slightly older dialog(1) requires --separate-output when using the
--checklist widget to force response to produce unquoted values (whereas in
stable/10 --checklist widget without --separate-output will only quote the
checklist labels in the response if the label is multi-word (contains any
whitespace).
Since these enhancements (see revisions 263956 and 264437) were developed
originally on 10, the --separate-output option was omitted. When merged to
stable/9, we (Allan Jude) and I found during testing that the "always-
quoting" of the response was causing things like struct interpolation to
fail (`f_struct device_$dev' would produce `f_struct device_\"da0\"' for
example -- literal quotes inherited from dialog(1) --checklist response).
To see the behavior, execute the following on stable/9 versus stable/10:
dialog --checklist disks: 0 0 0 da0 "" off da1 "" off
Check both items and hit enter. On stable/10, the response is:
da0 da1
On stable/9 the response is:
"da0" "da1"
If you use the --separate-output option, the response is the same for both:
da0
da1
So applying --separate-output on every platform until either one of two
things occurs 1) dialog(1,3) gets synchronized between stable/9, higher or
2) we drop support for stable/9.
mergemaster: Avoid "/var/tmp/temproot disappeared" if there is nothing to
compare.
Because of the change to find in SVN r253886, the entire temproot would be
deleted if it became empty, leading to a confusing message "*** FATAL ERROR:
The temproot directory ${TEMPROOT} has disappeared!"
Note that mergemaster does not do anything useful in this situation anyway
(e.g. put IGNORE_FILES="/etc/group /etc/master.passwd" in
/etc/mergemaster.rc and run mergemaster -p).
As noted in that commit, add -mindepth 1.

For increased compatibility with GNU units: support a -v option which
produces more verbose output when spitting out the answer.
GNU -v does additional work in the version, information, and check output which
we do not (yet?) replicate.
Lagg did not set the value of if_hw_tsomax, so when lagg
was stacked on top of network interfaces that set if_hw_tsomax,
tcp_output() would see the default value instead of the value
set by the network interface(s). This patch modifies lagg so that
it sets if_hw_tsomax to the minimum of the value(s) for the
underlying network interfaces.

Fix some off-by-one errors. The kve_end and rdl_eaddr fields contain the
first address after the end of the map entry and should therefore be
excluded.
Ensure that all eight syscall arguments are available to dtrace_probe(),
rather than just the first five. This is done by calling dtrace_probe()
through a function pointer, as in illumos.
DTrace's pid provider works by inserting breakpoint instructions at probe
sites and installing a hook at the kernel's trap handler. The fasttrap code
will emulate the overwritten instruction in some common cases, but otherwise
copies it out into some scratch space in the traced process' address space
and ensures that it's executed after returning from the trap.
In Solaris and illumos, this (per-thread) scratch space comes from some
reserved space in TLS, accessible via the fs segment register. This
approach is somewhat unappealing on FreeBSD since it would require some
modifications to rtld and jemalloc (for static TLS) to ensure that TLS is
executable, and would thus introduce dependencies on their implementation
details. I think it would also be impossible to safely trace static binaries
compiled without these modifications.
This change implements the functionality in a different way, by having
fasttrap map pages into the target process' address space on demand. Each
page is divided into 64-byte chunks for use by individual threads, and
fasttrap's process descriptor struct has been extended to keep track of
any scratch space allocated for the corresponding process.
With this change it's possible to trace all libc functions in a program,
e.g. with
Always install pkg.conf. Don't depend on MK_PKGBOOTSTRAP.
This file is used by pkg(8) from ports as well. Someone may
choose to not install pkg(7) but still want to consume
official packages by building or installing pkg(8) manually.

realpath(): Properly fail "." or ".." components after non-directories.
If realpath() is called on pathnames like "/dev/null/." or "/dev/null/..",
it should fail with [ENOTDIR]. Pathnames like "/dev/null/" already failed as
they should.
Also, put the check for non-directories after lstatting the previous
component instead of when the empty component (consecutive or trailing
slashes) is detected, saving an lstat() call and some lines of code.
Apparently some of the i386 boot blocks are so close to full that adding
single lines to ufsread.c spills them over. Duplicate a whole bunch of
code to get file sizes into boot1.efi/boot1.c rather than modifying
ufsread.c.
As part of this, install the tests(7) manual page unconditionally (not only
when WITH_TESTS=yes) so that users that have not yet enabled the build of
the test suite can read details on how to do so.
Add my copyright here. Most of this is unmodified from the original sparc64

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead

Don't apply ctf conversions in POSIX mode. These can't happen there
because they pollute the POSIX environment, which doens't allow
for these extentions. ctf conversions are really only relevant when
used in coordination with the rest of the bsd*.mk system anyway.
Leave them in place for the normal, non-posix enviornment since
they are quite useful there.
We no longer support upgrading from FreeBSD 4, so we don't need the
NOMAN and NOSHARED defines here. They have been obsolete for almost a
decade anyway.
Up the minimum system to build FreeBSD current to 8.0-RELEASE. The
issues with vendors that needed 7.x support have been resolved. Many
vendors are still using 8.x build platforms, however, so bumping this
up to 9.0 will have to wait until that is resolved. Actual support for
building from 8.x still relies on those vendors fixing bugs that are
present as most developers have moved onto 9.x or newer platforms.
Determine whether to build clang and its bootstrap tools the same
way. This allows a clang bootstrap to happen, even when WITHOUT_CLANG
is defined. This is a minimal version of a more extensive change which
can be MFC'd more easily. However, we have to also test to see if
we're building clang as not cc, since the bootstrap for that needs
these cross tools and it is easier to build them in just one place.
Fix a panic in zfs_rename().
this is due to a wrong dereference of a vnode when it's not locked and
can be (potentially) recycled. 'sdvp' cannot be locked on zfs_rename()
entry point because the VFS can't be sure that this scenario is
LOR-free (it might violate the parent->child lock acquisition rule).
Dereference 'tdvp' instead, which is already locked on entry, and access
'sdvp' fields only when it's safe, i.e. under ZFS_ENTER scope.
While at it, remove the usage of VOP_REALVP, as long as this is a NOP
on FreeBSD.
Add a simple EFI stub loader. This is a quick and dirty of boot1.chrp from
the PowerPC port with all the Open Firmware bits removed and replaced by
their EFI counterparts. On the whole, I think I prefer Open Firmware.
This code is supposed to be an immutable shim that sits on the EFI system
partition, loads /boot/loader.efi from UFS and tells the real loader what
disk/partition to look at. It finds the UFS root partition by the somewhat
braindead approach of picking the first UFS partition it can find. Better
approaches are called for, but this works for now. This shim loader will
also be useful for secure boot in the future, which will require some
rearchitecture.
Hide internal details of sbintime_t implementation wrapping INT64_MAX into
SBT_MAX, to make it more robust in case internal type representation will
change in the future. All the consumers were migrated to SBT_MAX and
every new consumer (if any) should from now use this interface.
As per POSIX, the -exec ... {} + primary always returns true, but a non-zero
exit status causes find to return a non-zero exit status itself. GNU does
the same, and also for -execdir ... {} +.
It does not make much sense to return false from the primary only when the
child process happens to be run.
The behaviour for -exec/-execdir ... ; remains unchanged: the primary
returns true or false depending on the exit status, and find's exit status
is unaffected.
Align and round the partitionable disk space to 4K by default.
Since this would also apply when recovering, make sure not to
align or round when that would have a partition fall outside
the partitionable area.
