Fix releasing the lock in the parent atrun process after the queue
directory has been processed. Otherwise, a long-running child process
caused other atrun invocations to stall unnecessarily.
Based on xlp_machdep.c and completed the list of options based on
boot/mips/beri/loader/metadata.c allow FDT configuration to set
command line options.
This leads to an interesting quesiton of future interactions with loader.
However for configurations without loader this allows bootverbose or boot
single user to be set by compiling a new kernel, which is good enough for
testing and debugging.
when watchdogd is asked to exit nicely (via SIGTERM) it will
stop timer. since watchdogd rc.d script is marked as 'shutdown'
it will exit (on shutdown) and stop timer. if system happens to
hung after watchdogd exited, manual reset is required. when one
operates in "lights-out" type of environments and without
readily available "remote hands" it could create a problem.
this provides ability to override "stop signal" for watchdogd.
default behavior is preserved, i.e. watchdogd will still be killed
via SIGTERM and timer will be stopped. in order to activate new
feature, one needs to put
watchdogd_sig_stop="KILL"
into /etc/rc.conf and also make sure watchdogd timeout is set
to long enough value allowing system to come back online before
timeout fires.
Fix VIRTUAL and PROF interval timers for short intervals, broken at r247903.
Due to the way those timers are implemented, we can't handle very short
intervals. In addition to that mentioned patch caused math overflows
for short intervals. To avoid that round those intervals to 1 tick.
Make it possible for the initiator side to operate in both proxy
and normal mode; this makes it possible to compile with the former
by default, but use it only when neccessary. That's especially
important for the userland part.
When switching variables to flags in r243185 a few cases were missed.
After r263152 this leaves unused variables if route(8) is compiled
without INET support.
Switch the remaining variable accesses to flags and remove now obsolete
variables.
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.
