03947063d0 Maintain two trees instead of one (old_chunks --> old_chunks_{ad,szad}) in
order to support re-use of multi-chunk unused regions within the DSS for
huge allocations.  This generalization is important to correct function
when mmap-based allocation is disabled.

Avoid zeroing re-used memory in the DSS unless it really needs to be
zeroed.

ebc87e7e0b Add the 'D' and 'M' run time options, and use them to control whether
memory is acquired from the system via sbrk(2) and/or mmap(2).  By default,
use sbrk(2) only, in order to support traditional use of resource limits.
Additionally, when both options are enabled, prefer the data segment to
anonymous mappings, in order to coexist better with large file mappings
in applications on 32-bit platforms.  This change has the potential to
increase memory fragmentation due to the linear nature of the data
segment, but from a performance perspective this is mitigated by the use
of madvise(2). [1]

Add the ability to interpret integer prefixes in MALLOC_OPTIONS
processing.  For example, MALLOC_OPTIONS=lllllllll can now be specified as
MALLOC_OPTIONS=9l.

- Use PTY* for all pty(4) related constants.
- Use PTMX* for all pts(4) related constants.
- Consistently use _PATH_DEV PTMX rather than "/dev/ptmx".
- Revert 1.7 and properly fix it by using the correct prefix string for

7cd4a83267 Since nan() is supposed to work the same as strtod("nan(...)", NULL),
my original implementation made both use the same code. Unfortunately,
this meant libm depended on a vendor header at compile time and previously-
unexposed vendor bits in libc at runtime.

Hence, I just wrote my own version of the relevant vendor routine. As it
turns out, mine has a factor of 8 fewer of lines of code, and is a bit more
readable anyway. The strtod() and *scanf() routines still use vendor code.

056c1a0528 Fix logical bug in the bzip2 reading code, which results in bogus EIO
returned on a perfectly valid bzip2 stream whose decompressed size
is multiple of read-ahead buffer size. Reproduce the problem is easy:
create some power-of-two sized file (truncate -s 1m file will do),
bzip2 it and try to load it as md_image from loader. See how it fails.

The bug doesn't affect gzip code (which most of bzip2-reading code was
copied from) probably due to the fact that libgzip doesn't report
Z_STREAM_END with the last block, but requires extra call to inflate()
to retrieve it and has some extra data in the input stream at that time.
However, apply similar fix to gzipfs.c just in the case the API will
change in the future to do what bzip2 code does.

Add some ifdef'ed code to enable testing bzipfs.c from witin normal
FreeBSD environment as opposed to the restricted loader one, so that
one can use gdb and whatnot.

3fe21f77bc Hide the building and installation of libgssapi behind the
WITHOUT_KERBEROS knob. While GSS can be used for other things
some third party software (most notably ports/x11/kdelibs3)
takes the presence of libgssapi as an indication that kerberos
is available, and attempts to link with the kerberos libs. If
they are not available, the build will fail.

Because you might want to use GSS but not kerberos, add a knob
to re-enable it if WITHOUT_KERBEROS is present.

Document the new knob, and the new behavior of WITHOUT_KERBEROS.

5ea8413d0a Implement dynamic load balancing of thread-->arena mapping, based on lock
contention.  The intent is to dynamically adjust to load imbalances, which
can cause severe contention.

Use pthread mutexes where possible instead of libc "spinlocks" (they aren't
actually spin locks).  Conceptually, this change is meant only to support
the dynamic load balancing code by enabling the use of spin locks, but it
has the added apparent benefit of substantially improving performance due to
reduced context switches when there is moderate arena lock contention.

Proper tuning parameter configuration for this change is a finicky business,
and it is very much machine-dependent.  One seemingly promising solution
would be to run a tuning program during operating system installation that
computes appropriate settings for load balancing.  (The pthreads adaptive
spin locks should probably be similarly tuned.)

doing the hard work of locking the arena and deallocating, try several times
to randomly insert the object into the vector using atomic operations.

This approach is particularly effective at reducing contention for
multi-threaded applications that use the producer-consumer model, wherein
one producer thread allocates objects, then multiple consumer threads
deallocate those objects.

7416cdabcd Add my recent work of adaptive spin mutex code. Use two environments variable
to tune pthread mutex performance:
1. LIBPTHREAD_SPINLOOPS
	If a pthread mutex is being locked by another thread, this environment
	variable sets total number of spin loops before the current thread
	sleeps in kernel, this saves a syscall overhead if the mutex will be
	unlocked very soon (well written application code).
2. LIBPTHREAD_YIELDLOOPS
	If a pthread mutex is being locked by other threads, this environment
	variable sets total number of sched_yield() loops before the currrent
	thread sleeps in kernel. if a pthread mutex is locked, the current thread
	gives up cpu, but will not sleep in kernel, this means, current thread
	does not set contention bit in mutex, but let lock owner to run again
	if the owner is on kernel's run queue, and when lock owner unlocks the
	mutex, it does not need to enter kernel and do lots of work to resume
	mutex waiters, in some cases, this saves lots of syscall overheads for
	mutex owner.

In my practice, sometimes LIBPTHREAD_YIELDLOOPS can massively improve performance
than LIBPTHREAD_SPINLOOPS, this depends on application. These two environments
are global to all pthread mutex, there is no interface to set them for each
pthread mutex, the default values are zero, this means spinning is turned off
by default.

2017a7cdfe Add a new "non-portable" mutex type, PTHREAD_MUTEX_ADAPTIVE_NP. This
is also implemented in glibc and is used by a number of existing
applications (mysql, firefox, etc).

This mutex type is a default mutex with the additional property that
it spins briefly when attempting to acquire a contested lock, doing
trylock operations in userland before entering the kernel to block if
eventually unsuccessful.

The expectation is that applications requesting this mutex type know
that the mutex is likely to be only held for very brief periods, so it
is faster to spin in userland and probably succeed in acquiring the
mutex, than to enter the kernel and sleep, only to be woken up almost
immediately.  This can help significantly in certain cases when
pthread mutexes are heavily contended and held for brief durations
(such as mysql).

Spin up to 200 times before entering the kernel, which represents only
a few us on modern CPUs.  No performance degradation was observed with
this value and it is sufficient to avoid a large performance drop in
mysql performance in the heavily contended pthread mutex case.

The libkse implementation is a NOP.

c383d82e4d When skipping input data, don't overflow a 32-bit size_t.
This can only happen on 32-bit systems when you're reading
an uncompressed archive and the skip request is an exact
multiple of 4G (e.g., skipping a tar entry with an 8G body).

The symptom is that the read_ahead() ends up returning zero
bytes, and the extraction stops with a premature end-of-file.

Using '1' here is more correct anyway, as it allows read_ahead()
to function opportunistically and minimize copying.

7ab24ea3b9 Introduce a way to make pure kernal threads.
kthread_add() takes the same parameters as the old kthread_create()
plus a pointer to a process structure, and adds a kernel thread
to that process.

kproc_kthread_add() takes the parameters for kthread_add,
plus a process name and a pointer to a pointer to a process instead of just
a pointer, and if the proc * is NULL, it creates the process to the
specifications required, before adding the thread to it.

All other old kthread_xxx() calls return, but act on (struct thread *)
instead of (struct proc *). One reason to change the name is so that
any old kernel modules that are lying around and expect kthread_create()
to make a process will not just accidentally link.

fix top to show  kernel threads by their thread name in -SH mode
add a tdnam formatting option to ps to show thread names.

make all idle threads actual kthreads and put them into their own idled process.
make all interrupt threads kthreads and put them in an interd process
(mainly for aesthetic and accounting reasons)
rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper'

f352a0d45f First cut at support for booting a GPT labeled disk via the BIOS bootstrap
on i386 and amd64 machines.  The overall process is that /boot/pmbr lives
in the PMBR (similar to /boot/mbr for MBR disks) and is responsible for
locating and loading /boot/gptboot.  /boot/gptboot is similar to /boot/boot
except that it groks GPT rather than MBR + bsdlabel.  Unlike /boot/boot,
/boot/gptboot lives in its own dedicated GPT partition with a new
"FreeBSD boot" type.  This partition does not have a fixed size in that
/boot/pmbr will load the entire partition into the lower 640k.  However,
it is limited in that it can only be 545k.  That's still a lot better than
the current 7.5k limit for boot2 on MBR.  gptboot mostly acts just like
boot2 in that it reads /boot.config and loads up /boot/loader.  Some more
details:
- Include uuid_equal() and uuid_is_nil() in libstand.
- Add a new 'boot' command to gpt(8) which makes a GPT disk bootable using
  /boot/pmbr and /boot/gptboot.  Note that the disk must have some free
  space for the boot partition.
  - This required exposing the backend of the 'add' function as a
    gpt_add_part() function to the rest of gpt(8).  'boot' uses this to
    create a boot partition if needed.
- Don't cripple cgbase() in the UFS boot code for /boot/gptboot so that
  it can handle a filesystem > 1.5 TB.
- /boot/gptboot has a simple loader (gptldr) that doesn't do any I/O
  unlike boot1 since /boot/pmbr loads all of gptboot up front.  The
  C portion of gptboot (gptboot.c) has been repocopied from boot2.c.
  The primary changes are to parse the GPT to find a root filesystem
  and to use 64-bit disk addresses.  Currently gptboot assumes that the
  first UFS partition on the disk is the / filesystem, but this algorithm
  will likely be improved in the future.
- Teach the biosdisk driver in /boot/loader to understand GPT tables.
  GPT partitions are identified as 'disk0pX:' (e.g. disk0p2:) which is
  similar to the /dev names the kernel uses (e.g. /dev/ad0p2).
- Add a new "freebsd-boot" alias to g_part() for the new boot UUID.

da65d6fe83 - Given that we tell the compiler that struct ip is packed and 32-bit
aligned, GCC 4.2.1 also generates code for sendudp() that assumes
  this alignment. GCC 4.2.1 however doesn't 32-bit align wbuf, causing
  the loader to crash due to an unaligned access of wbuf in sendudp()
  when netbooting sparc64. Solve this by specifying wbuf as packed and
  32-bit aligned, too. As for lastdata and readudp() this currently is
  no issue when compiled with GCC 4.2.1, though give lastdata the same
  treatment as wbuf for consistency and possibility of being affected

99f6b270e3 Import OpenBSD's sysctl hardware sensors framework.
This commit includes the following core components:

 * sample configuration file for sensorsd
 * rc(8) script and glue code for sensorsd(8)
 * sysctl(3) doc fixes for CTL_HW tree
 * sysctl(3) documentation for hardware sensors
 * sysctl(8) documentation for hardware sensors
 * support for the sensor structure for sysctl(8)
 * rc.conf(5) documentation for starting sensorsd(8)
 * sensor_attach(9) et al documentation
 * /sys/kern/kern_sensors.c
   o sensor_attach(9) API for drivers to register ksensors
   o sensor_task_register(9) API for the update task
   o sysctl(3) glue code
   o hw.sensors shadow tree for sysctl(8) internal magic
 * <sys/sensors.h>
 * HW_SENSORS definition for <sys/sysctl.h>
 * sensors display for systat(1), including documentation
 * sensorsd(8) and all applicable documentation

The userland part of the framework is entirely source-code
compatible with OpenBSD 4.1, 4.2 and  -current as of today.

All sensor readings can be viewed with `sysctl hw.sensors`,
monitored in semi-realtime with `systat -sensors` and also
logged with `sensorsd`.

367ed4e13d The problem is: currently our single byte ctype(3) functions are broken
for wide characters locales in the argument range >= 0x80 - they may
return false positives.

Example 1: for UTF-8 locale we currently have:
iswspace(0xA0)==1 and isspace(0xA0)==1
(because iswspace() and isspace() are the same code)
but must have
iswspace(0xA0)==1 and isspace(0xA0)==0
(because there is no such character and all others in the range
0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte
range because our internal wchar_t representation for UTF-8 is UCS-4).

Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may
return false positives (must be 0).
(because iswalpha() and isalpha() are the same code)

This change address this issue separating single byte and wide ctype
and also fix iswascii() (currently iswascii() is broken for
arguments > 0xFF).
This change is 100% binary compatible with old binaries.

mount(8) does the kill(mountpid, SIGHUP). If mountd pidfile is truncated,
that would result in the SIGHUP delivered to the mount' process group

b61ce5b0e6 - Move all of the PS_ flags into either p_flag or td_flags.
- p_sflag was mostly protected by PROC_LOCK rather than the PROC_SLOCK or
   previously the sched_lock.  These bugs have existed for some time.
 - Allow swapout to try each thread in a process individually and then
   swapin the whole process if any of these fail.  This allows us to move
   most scheduler related swap flags into td_flags.
 - Keep ki_sflag for backwards compat but change all in source tools to

68f0154dcf This commit updates libarchive to be compatible with
GNU tar 1.17's implementation of --posix --sparse,
at the cost of losing compatibility with GNU tar 1.16.
Fortunately, the 1.17 implementation actually makes sense,
so the libarchive code is now a bit more straightforward
than before.

Background:  GNU tar 1.16 defined a new way to store
sparse files in --posix archives.  Unfortunately,
the implementation incorrectly inserted several
blocks of null padding after each such entry.
As a result, non-GNU tar implementations saw the
archive as truncated after any sparse entry.
This was fixed in GNU tar 1.17 at the cost of
losing compatibility with GNU tar 1.16 for this
new format (which is not the default, so hopefully
rarely used).  Libarchive recently gained support
for reading the GNU tar 1.16 formats; this commit
updates it to read the GNU tar 1.17 variant instead.

9136384dc2 Make suid/sgid restore be "opportunistic" if
owner restore is not requested.  If you ask
for permissions to be restored but not owner,
you will now get no error if suid/sgid bits
cannot be set.  (It's a security hole to restore
suid/sgid bits if the owner/group aren't restored.)

This fixes an obscure problem where a simple
"tar -xf" with no other options will sometimes
fail gratuitously because of suid/sgid bits.
This is causing occasional problems for people
using bsdtar as a drop-in replacement for
"that other tar program." ;-)

Note: If you do ask for owner restore, then suid/sgid
restore failures still issue an error.  This
only suppresses the error in the case where an
suid/sgid bit restore fails because of an owner
mismatch and owner restore was not requested.

f6d19aee04 Update the tests for reading the various GNU tar sparse formats.
In particular:
  * Include a second entry in all of the test archives (to catch errors
    with intermediate padding)
  * Test the GNU tar 1.17 version of "posix sparse format 1.0"
    instead of the GNU tar 1.16 version (the latter is no longer
    supported by GNU tar).

Right now, libarchive fails this test because I originally
implemented the GNU tar 1.16 version of "posix sparse format 1.0".
I'll fix libarchive shortly.

8a4974cb5a Improve error handling in libdisk while parsing the kern.geom.conftxt sysctl.
Previously, any parse error will result in the calling program exiting with an
unpleasant message. This change will cause libdisk to issue a warning and
ignore lines it cannot parse instead of bluntly terminating the unfortunate
enough program.

This change will allow you to use sysinstall if you have a NTFS parition with
a space in the name (such as 'Win Xp'). In such a case, a line like the
following will appear in the kern.geom.conftxt output:

2 LABEL ntfs/Win Xp 209818635264 512 i 0 o 0

As the fields are space-separated, libdisk would go beserk and exit the program.
This would happen if using FreeBSD 7.0 snapshot images (as GEOM_LABEL is in
the installation kernel as well), thus making it impossible to install FreeBSD
without renaming your NTFS paritions.

   o Rename some functions for clarity:
     - sctp_add/del_local_addr_assoc to xxx_local_addr_restricted()
     - asconf related iterator functions to sctp_asconf_iterator_xxx()

   o Fix bug when the same address is deleted and added (and removed from
     the asconf queue) where the ifa is "freed" twice refcount wise,
     possibly freeing it completely.

   o Fix bug in output where the first ASCONF would not go out after the
     last address is changed (e.g. only goes out when retransmitted).

   o Fix bug where multiple ASCONFs can be bundled in the same packet with
     the and with the same serial numbers.

   o Fix asconf stcb iterator to not send ASCONF until after all work
     queue entries have been processed.

   o Change behavior so that when the last address is deleted (auto asconf
     on a bound all endpoint) no action is taken until an address is
     added; at that time, an ASCONF add+delete is sent (if the assoc
     is still up).

   o Fix local address counting so that address scoping is taken into
     account.

   o #ifdef SCTP_TIMER_BASED_ASCONF the old timer triggered sending
     of ASCONF (after an RTO).  The default now is to send
     ASCONF immediately (except for the case of changing/deleting the
     last usable address).

9bab236702 Added environ-replacement detection. For programs that "clean" (i.e., su)
or replace (i.e., zdump) the environment after a call to setenv(), putenv()
or unsetenv() has been made, a few changes were made.
  - getenv() will return the value from the new environ array.
  - setenv() was split into two functions:  __setenv() which is most of the
    previous setenv() without checks on the name and setenv() which
    contains the checks before calling __setenv().
  - setenv(), putenv() and unsetenv() will unset all previous values and
    call __setenv() on all entries in the new environ array which in turn
    adds them to the end of the envVars array.  Calling __setenv() instead
    of setenv() is done to avoid the temporary replacement of the '=' in a
    string with a NUL byte.  Some strings may be read-only data.

Added more regression checks for clearing the environment array.

Replaced gettimeofday() with getrusage() in timing regression check for
better accuracy.

Fixed an off-by-one bug in __remove_putenv() in the use of memmove().  This
went unnoticed due to the allocation of double the number of environ
entries when building envVars.

Fixed a few spelling mistakes in the comments.

d3bb697513 archive_string_ensure() used to call exit(3) if it
couldn't allocate more memory for a string.  Change
this so it returns NULL in that case, and update
all of its callers to handle the error.  Some of
those callers can now return errors back to the
client instead of calling exit(3).

2b851aeb63 Disconnect netatm from the build as it is not MPSAFE and relies on
NET_NEEDS_GIANT, which will shortly be removed.  This is done in a
away that it may be easily reattached to the build before 7.1 if
appropriate locking is added.  Specifics:

- Don't install netatm include files
- Disconnect netatm command line management tools
- Don't build libatm
- Don't include ATM parts in rescue or sysinstall
- Don't install sample configuration files and documents
- Don't build kernel support as a module or in NOTES
- Don't build netgraph wrapper nodes for netatm

This removes the last remaining consumer of NET_NEEDS_GIANT.

b54d3a6c48 - Modular congestion control, with RFC2581 being the default.
- CMT_PF states added (w/sysctl to turn the PF version on)
- sctp_input.c had a missing incr of cookie case when the
  auth was bad. This meant a free was called without an
  increment to refcnt, added increment like rest of code.
- There was a case, unlikely, when the scope of the destination
  changed (this is a TSNH case). In that case, it would not free
  the alloc'ed asoc (in sctp_input.c).
- When listed addresses found a colliding cookie/Init, then
  the collided upon tcb was not unlocked in sctp_pcb.c
- Add error checking on arguments of sctp_sendx(3) to prevent it from
  referencing a NULL pointer.
- Fix an error return of sctp_sendx(3), it was returing
  ENOMEM not -1.
- Get assoc id was changed to use the sanctified socket api
  method for getting a assoc id (PEER_ADDR_INFO instead of
  PEER_ADDR_PARAMS).
- Fix it so a peeled off socket will get a proper error return
  if it trys to send to a different address then it is connected to.
- Fix so that select_a_stream can avoid an endless loop that
  could hang a caller.
- time_entered (state set time) was not being set in all cases
  to the time we went established.

anyone interested should just checkout and use this version

4dd719bd7f Change the C wrappers for mmap/lseek/pread/pwrite/truncate/ftruncate to
call the pad-less versions of the corresponding syscalls if the running
kernel supports it.  Check kern.osreldate once per program and cache the
result to select the appropriate syscall.  This maintains userland
compatability with kernel.old's from quite a while back.

65a6d893ba Classify mmap, lseek, pread, pwrite, truncate, ftruncate as pseudo
syscalls, unless WITHOUT_SYSCALL_COMPAT is defined.  The default case
will have the .c wrappers still.  If you define WITHOUT_SYSCALL_COMPAT,
the .c wrappers will go away and libc will make direct syscalls.

After 7-stable starts, the direct syscall method will be default.
