86b360ada3 Instead of defining LLVM_MULTITHREADED as 0 or 1, define or undefine it,
and test appropriately.  Otherwise it might erroneously pick up some

ad30f8e79b Add the BSD-licensed Citrus iconv to the base system with default off
setting. It can be built by setting the WITH_ICONV knob. While this
knob is unset, the library part, the binaries, the header file and
the metadata files will not be built or installed so it makes no impact
on the system if left turned off.

This work is based on the iconv implementation in NetBSD but a great
number of improvements and feature additions have been included:

- Some utilities have been added. There is a conversion table generator,
  which can compare conversion tables to reference data generated by
  GNU libiconv. This helps ensuring conversion compatibility.
- UTF-16 surrogate support and some endianness issues have been fixed.
- The rather chaotic Makefiles to build metadata have been refactored
  and cleaned up, now it is easy to read and it is also easier to add
  support for new encodings.
- A bunch of new encodings and encoding aliases have been added.
- Support for 1->2, 1->3 and 1->4 mappings, which is needed for
  transliterating with flying accents as GNU does, like "u.
- Lots of warnings have been fixed, the major part of the code is
  now WARNS=6 clean.
- New section 1 and section 5 manual pages have been added.
- Some GNU-specific calls have been implemented:
  iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into()
- Support for GNU's //IGNORE suffix has been added.
- The "-" argument for stdin is now recognized in iconv(1) as per POSIX.
- The Big5 conversion module has been fixed.
- The iconv.h header files is supposed to be compatible with the
  GNU version, i.e. sources should build with base iconv.h and
  GNU libiconv. It also includes a macro magic to deal with the
  char ** and const char ** incompatibility.
- GNU compatibility: "" or "char" means the current local
  encoding in use
- Various cleanups and style(9) fixes.

7ec9c8d170 Remove sysctl vm.max_proc_mmap used to protect from KVA space exhaustion.
As it was pointed out by Alan Cox, that no longer serves its purpose with
the modern UMA allocator compared to the old one used in 4.x days.

The removal of sysctl eliminates max_proc_mmap type overflow leading to
the broken mmap(2) seen with large amount of physical memory on arches
with factually unbound KVA space (such as amd64).  It was found that
slightly less than 256GB of physmem was enough to trigger the overflow.

ceed9a6cf9 Fix the 32-bit build stage on amd64 when WITH_CTF is enabled. It seems
ctfconvert will corrupt object files that are compiled with -g, if it is
not run with -g itself.

To fix it, remove -g from CFLAGS in lib/librt/Makefile.  If you need to
compile this library with debug info, use DEBUG_FLAGS=-g instead, which
will work correctly, even when using WITH_CTF.

while signal names with a lower case 'i' are no longer accepted, and the

of a dotted capital 'I'.

de788839e2 libkvm: fix process runtime calculation on crashdumps
Fix a long standing bug, where the procs ticks where assumed to be in
us. Instead, read cpu_tick_frequency from the kernel and use the same
logic to convert runtime. This is still too optimistic in that it
assumes cpu_tick_frequency is available and fixed. Since this function
is only called on crashdumps, I think we can live with that. Testing has
shown the values to be correct for different kern.hz inside Virtualbox.

9ef4e3afcb Apply a workaround for a binutils issue with the .note.ABI-tag section
generated from lib/csu/common/crtbrand.c (which ultimately ends up in
executables and shared libraries, via crt1.o, gcrt1.o or Scrt1.o).

For all arches except sparc, gcc emits the section directive for the
abitag struct in crtbrand.c with a PROGBITS type.  However, newer
versions of binutils (after 2.16.90) require the section to be of NOTE
type, to guarantee that the .note.ABI-tag section correctly ends up in
the first page of the final executable.

Unfortunately, there is no clean way to tell gcc to use another section
type, so crtbrand.c (or the C files that include it) must be compiled in
multiple steps:

- Compile the .c file to a .s file.
- Edit the .s file to change the 'progbits' type to 'note', for the section
  directive that defines the .note.ABI-tag section.
- Compile the .s file to an object file.

These steps are done in the invididual Makefiles for each applicable arch.

_rtld_get_stack_prot() may return PROT_READ | PROT_WRITE, but thread

- Add sub-function UMTX_OP_NWAKE_PRIVATE to wake up N channels in single
  system call. Create userland sleep queue for condition variable, in most
  cases, thread will wait in the queue, the pthread_cond_signal will defer
  thread wakeup until the mutex is unlocked, it tries to avoid an extra
  system call and a extra context switch in time window of pthread_cond_signal
  and pthread_mutex_unlock.

The changes are part of process-shared mutex project.

e7780530fa Add a "kernel" log function, based on e_log.c, which is useful for
implementing accurate logarithms in different bases.  This is based
on an approach bde coded up years ago.

This function should always be inlined; it will be used in only a few
places, and rudimentary tests show a 40% performance improvement in
implementations of log2() and log10() on amd64.

The kernel takes a reduced argument x and returns the same polynomial
approximation as e_log.c, but omitting the low-order term. The low-order
term is much larger than the rest of the approximation, so the caller of
the kernel function can scale it to the appropriate base in extra precision
and obtain a much more accurate answer than by using log(x)/log(b).

06e794928b Add Serial Management Protocol (SMP) passthrough support to CAM.
This includes support in the kernel, camcontrol(8), libcam and the mps(4)
driver for SMP passthrough.

The CAM SCSI probe code has been modified to fetch Inquiry VPD page 0x00
to determine supported pages, and will now fetch page 0x83 in addition to
page 0x80 if supported.

Add two new CAM CCBs, XPT_SMP_IO, and XPT_GDEV_ADVINFO.  The SMP CCB is
intended for SMP requests and responses.  The ADVINFO is currently used to
fetch cached VPD page 0x83 data from the transport layer, but is intended
to be extensible to fetch other types of device-specific data.

SMP-only devices are not currently represented in the CAM topology, and so
the current semantics are that the SIM will route SMP CCBs to either the
addressed device, if it contains an SMP target, or its parent, if it
contains an SMP target.  (This is noted in cam_ccb.h, since it will change
later once we have the ability to have SMP-only devices in CAM's topology.)

smp_all.c,
smp_all.h:		New helper routines for SMP.  This includes
			SMP request building routines, response parsing
			routines, error decoding routines, and structure
			definitions for a number of SMP commands.

libcam/Makefile:	Add smp_all.c to libcam, so that SMP functionality
			is available to userland applications.

camcontrol.8,
camcontrol.c:		Add smp passthrough support to camcontrol.  Several
			new subcommands are now available:

			'smpcmd' functions much like 'cmd', except that it
			allows the user to send generic SMP commands.

			'smprg' sends the SMP report general command, and
			displays the decoded output.  It will automatically
			fetch extended output if it is available.

			'smppc' sends the SMP phy control command, with any
			number of potential options.  Among other things,
			this allows the user to reset a phy on a SAS
			expander, or disable a phy on an expander.

			'smpmaninfo' sends the SMP report manufacturer
			information and displays the decoded output.

			'smpphylist' displays a list of phys on an
			expander, and the CAM devices attached to those
			phys, if any.

cam.h,
cam.c:			Add a status value for SMP errors
			(CAM_SMP_STATUS_ERROR).

			Add a missing description for CAM_SCSI_IT_NEXUS_LOST.

			Add support for SMP commands to cam_error_string().

cam_ccb.h:		Rename the CAM_DIR_RESV flag to CAM_DIR_BOTH.  SMP
			commands are by nature bi-directional, and we may
			need to support bi-directional SCSI commands later.

			Add the XPT_SMP_IO CCB.  Since SMP commands are
			bi-directional, there are pointers for both the
			request and response.

			Add a fill routine for SMP CCBs.

			Add the XPT_GDEV_ADVINFO CCB.  This is currently
			used to fetch cached page 0x83 data from the
			transport later, but is extensible to fetch many
			other types of data.

cam_periph.c:		Add support in cam_periph_mapmem() for XPT_SMP_IO
			and XPT_GDEV_ADVINFO CCBs.

cam_xpt.c:		Add support for executing XPT_SMP_IO CCBs.

cam_xpt_internal.h:	Add fields for VPD pages 0x00 and 0x83 in struct
			cam_ed.

scsi_all.c:		Add scsi_get_sas_addr(), a function that parses
			VPD page 0x83 data and pulls out a SAS address.

scsi_all.h:		Add VPD page 0x00 and 0x83 structures, and a
			prototype for scsi_get_sas_addr().

scsi_pass.c:		Add support for mapping buffers in XPT_SMP_IO and
			XPT_GDEV_ADVINFO CCBs.

scsi_xpt.c:		In the SCSI probe code, first ask the device for
			VPD page 0x00.  If any VPD pages are supported,
			that page is required to be implemented.  Based on
			the response, we may probe for the serial number
			(page 0x80) or device id (page 0x83).

			Add support for the XPT_GDEV_ADVINFO CCB.

sys/conf/files:		Add smp_all.c.

mps.c:			Add support for passing in a uio in mps_map_command(),
			so we can map a S/G list at once.

			Add support for SMP passthrough commands in
			mps_data_cb().  SMP is a special case, because the
			first buffer in the S/G list is outbound and the
			second buffer is inbound.

			Add support for warning the user if the busdma code
			comes back with more buffers than will work for the
			command.  This will, for example, help the user
			determine why an SMP command failed if busdma comes
			back with three buffers.

mps_pci.c:		Add sys/uio.h.

mps_sas.c:		Add the SAS address and the parent handle to the
			list of fields we pull from device page 0 and cache
			in struct mpssas_target.  These are needed for SMP
			passthrough.

			Add support for the XPT_SMP_IO CCB.  For now, this
			CCB is routed to the addressed device if it supports
			SMP, or to its parent if it does not and the parent
			does.  This is necessary because CAM does not
			currently support SMP-only nodes in the topology.

			Make SMP passthrough support conditional on
			__FreeBSD_version >= 900026.  This will make it
			easier to MFC this change to the driver without
			MFCing the CAM changes as well.

mps_user.c:		Un-staticize mpi_init_sge() so we can use it for
			the SMP passthrough code.

mpsvar.h:		Add a uio and iovecs into struct mps_command for
			SMP passthrough commands.

			Add a cm_max_segs field to struct mps_command so
			that we can warn the user if busdma comes back with
			too many segments.

			Clear the cm_reply when a command gets freed.  If
			it is not cleared, reply frames will eventually get
			freed into the pool multiple times and corrupt the
			pool.  (This fix is from scottl.)

			Add a prototype for mpi_init_sge().

sys/param.h:		Bump __FreeBSD_version to 900026 for the for the
			inclusion of the XPT_GDEV_ADVINFO and XPT_SMP_IO
			CAM CCBs.

e61ffaea2a Fix bug in jn(3) and jnf(3) that led to -inf results
Explanation by Steve:
jn[f](n,x) for certain ranges of x uses downward recursion to compute
the value of the function.  The recursion sequence that is generated is
proportional to the actual desired value, so a normalization step is
taken.  This normalization is j0[f](x) divided by the zeroth sequence
member.  As Bruce notes, near the zeros of j0[f](x) the computed value
can have giga-ULP inaccuracy. I found for the 1st zero of j0f(x) only
the leading decimal digit is correct.  The solution to the issue is
fairly straight forward.  The zeros of j0(x) and j1(x) never coincide,
so as j0(x) approaches a zero, the normalization constant switches to
j1[f](x) divided by the 2nd sequence member.  The expectation is that
j1[f](x) is a more accurately computed value.

5c9d0a9ad3 This commit implements the SO_USER_COOKIE socket option, which lets
you tag a socket with an uint32_t value. The cookie can then be
used by the kernel for various purposes, e.g. setting the skipto
rule or pipe number in ipfw (this is the reason SO_USER_COOKIE has
been implemented; however there is nothing ipfw-specific in its
implementation).

The ipfw-related code that uses the optopn will be committed separately.

This change adds a field to 'struct socket', but the struct is not
part of any driver or userland-visible ABI so the change should be
harmless.

290e14f881 amd64: introduce minidump version 2
After KVA space was increased to 512GB on amd64 it became impractical
to use PTEs as entries in the minidump map of dumped pages, because size
of that map alone would already be 1GB.
Instead, we now use PDEs as page map entries and employ two stage lookup
in libkvm: virtual address -> PDE -> PTE -> physical address.  PTEs are
now dumped as regular pages.  Fixed page map size now is 2MB.

libkvm keeps support for accessing amd64 minidumps of version 1.
Support for 1GB pages is added.

Many thanks to Alan Cox for his guidance, numerous reviews, suggestions,
enhancments and corrections.

e7032b4cdd Change libvgl's set4pixels() and set2lines() functions from plain
'inline' to 'static inline'.  Otherwise, a C99 compiler (such as clang)
will output an undefined symbol for those functions in the resulting
object file.  (Even gcc will do this, when you use "-std=c99".)

This should fix the "undefined reference to `set4pixels'" errors that
some people were seeing during ports building, when their world was

220856f376 libc: Remove the i386 assembler version of strlen(3).
On anything modern, the C version, which processes a word at a time, is much
faster. The Intel optimization manual explicitly warns against using REP
prefixes with SCAS or CMPS, which is exactly what the assembler version
does.

A simple test on a Phenom II showed the C version, compiled with -O2, to be
about twice as fast determining the length of 100000 strings between 0 and
255 bytes long.

mark temp2 volatile (only in case of compilation with clang) to force
clang to pop it correctly.  No binary change when compiled with gcc.

This fixes ldexp() when compiled with clang on amd64, which makes
drand48() and friends work correctly again, and this in turn fixes
perl's tempfile().

8f7f5a7f26 Fix exec_imgact_shell()'s handling of two error cases: (1) Previously, if
the first line of a script exceeded MAXSHELLCMDLEN characters, then
exec_imgact_shell() silently truncated the line and passed on the truncated
interpreter name or argument.  Now, exec_imgact_shell() will fail and return
ENOEXEC, which is the commonly used errno among Unix variants for this type
of error. (2) Previously, exec_imgact_shell()'s check on the length of the
interpreter's name was ineffective.  In other words, exec_imgact_shell()
could not possibly fail and return ENAMETOOLONG.  The reason being that the
length of the interpreter name had to exceed MAXSHELLCMDLEN characters in
order that ENAMETOOLONG be returned.  But, the search for the end of the
interpreter name stops after at most MAXSHELLCMDLEN - 2 characters are
scanned.  (In the end, this particular error is eventually discovered
outside of exec_imgact_shell() and ENAMETOOLONG is returned.  So, the real
effect of this second change is that the error is detected earlier, in
exec_imgact_shell().)

Update the definition of MAXINTERP to the actual limit on the size of
the interpreter name that has been in effect since r142453 (from
2005).

10f3ae5899 Merge from tbemd, with a small amount of rework:
For all libthr contexts, use ${MACHINE_CPUARCH}
for all libc contexts, use ${MACHINE_ARCH} if it exists, otherwise use
${MACHINE_CPUARCH}
Move some common code up a layer (the .PATH statement was the same in
all the arch submakefiles).

83c9e0893f Because POSIX does not allow EINTR to be returned from sigwait(),
add a wrapper for it in libc and rework the code in libthr, the
system call still can return EINTR, we keep this feature.

ea22f625a7 libelf is overly strict about the type and alignment of Elf_Data
objects inside one ELF section, which prevents the creation of a ELF
section with mixed data types. For example, gcc LTO use libelf to
create a .gnu_lto_XXX section that contains integers and a string
table, which doesn't work with our libelf implementation.

The changes made in this commit include:
* Allow Elf_Data type to be different than section type.
* Relax Elf_Data alignment check.
* Align each Elf_Data by their own alignment instead of section alignment.

b3c63ff614 libedit: Try to map <Delete> to ed-delete-next-char.
This adds a new "arrow" key "delete" corresponding to the kD termcap value.
It only works if that is a sequence such as "\033[3~"; if it is "\177", the
em-delete-prev-char or ed-delete-prev-char from the single-character
mappings remains. It turns out that most terminals (xterm and alikes,
syscons in xterm mode) produce "\033[3~" by default so <Delete> has the
expected effect.

This also means that things need to be considerably misconfigured for
<Backspace> to perform a <Delete> action.

96e75396e1 libedit: Do not move the cursor for ed-delete-next-char in emacs mode.
This makes ed-delete-next-char suitable for mapping to the <Delete> key.

de5f647070 Modify lib/libstand/nfs.c to use NFSv3 instead of NFSv2.
This allows the nfs_getrootfh() function to return the
correct file handle size to pxe.c for pxeboot. It also
results in NFSv2 no longer being used by default anywhere
in FreeBSD. If built with OLD_NFSV2 defined, the old
code that predated this patch will be built and NFSv2
will be used.
