a7afea4382 Do not force to run atexit handlers, which text comes from a dso
owning the handle passed to __cxa_finalize() but which are registered
by other dso, when the process is inside exit(3).

Running them makes the destruction order wrong, and there is hope that
such destructors would not call dlclose(3), since it is pointless at
this stage of the process existence.

The change effectively disables the r211706 after the exit(3) is
called.

7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

08e3ff329a Add HPET device emulation to bhyve.
bhyve supports a single timer block with 8 timers. The timers are all 32-bit
and capable of being operated in periodic mode. All timers support interrupt
delivery using MSI. Timers 0 and 1 also support legacy interrupt routing.

At the moment the timers are not connected to any ioapic pins but that will
be addressed in a subsequent commit.

This change is based on a patch from Tycho Nightingale (tycho.nightingale@pluribusnetworks.com).

7c5b23111c Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns EILSEQ
when there is an invalid character in the output codeset while it is
valid in the input.  However, POSIX requires iconv() to perform an
implementation-defined conversion on the character.  So, Citrus iconv converts
such a character to a special character which means it is invalid in the
output codeset.

This is not a problem in most cases but some software like libxml2 depends
on GNU's behavior to determine if a character is output as-is or another form
such as a character entity (&#NNN;).

0a9655a082 If check_deferred_signal() execution needs binding of PLT symbol,
unlocking the rtld bind lock results in the processing of ast and
recursing into the check_deferred_signal().  Nested execution of
check_deferred_signal() delivers the signal to user code and clears
si_signo.  On return, top-level check_deferred_signal() frame
continues delivering the same signal one more time, but now with zero
si_signo.

Fix this by adding a flag to indicate that deferred delivery is
running, so check_deferred_signal() should avoid doing anything. Since
user signal handler is allowed to modify the passed machine context to
make return from the signal handler to cause arbitrary jump, or do
longjmp(). For this case, also clear the flag in thr_sighandler(),
since kernel signal delivery means that nested delivery code should
not run right now.

204957ef5e Bug fixes in iconv(3) UTF-7 support.
- Add ' to the list of directly encoded characters and * to the list of
  optionally directly encoded characters as per RFC 2152.

- In _citrus_UTF7_mbtoutf16 on end of input when the next output character
  has only been partially decoded, save a copy of the buffer of input
  characters (not just its length).  On the next call with more input
  characters this buffer is reprocessed together with the new input to
  form a fully decoded output character.

- At the end of a base64 encoded sequence fully discard '-' (BASE64_OUT)
  by decrementing psenc->chlen and i.  This is needed to make room in
  psenc->ch (input buffer) in case the next input character starts a new
  base64 encoded sequence.  And also, if this is the end of input and no
  output character can be returned, this brings the encoder in the initial
  state as indicated by _citrus_UTF7_stdenc_get_state_desc_generic which
  is used by the caller to distinguish between no output and partial
  output.

- In _citrus_UTF7_mbrtowc_priv pass the s parameter (input pointer)
  directly to _citrus_UTF7_mbtoutf16 instead of a copy (s0).  This way s
  is updated correctly in case of errors.

- In _citrus_UTF7_mbrtowc_priv when called with psenc->surrogate set
  (previous call did not have enough input), retrieve the previously
  decoded UTF-16 character from (psenc->cache >> psenc->bits) instead of
  (psenc->cache >> 2).

When building various programs from a single Makefile, program-specific

obvious typo to fix the build when WITH_TESTS=yes.

I am not sure how this ever worked before given that manual inspection

two components is a dot and not an underscore... but I suspect the

091b8336ae Attempt to move the POSIX iconv* symbols out of runtime linker space.
FreeBSD systems usually implemented this as a third party module and
our implementation hasn't played as nicely with the old way as it could
have.

To that end:
* Rename the iconv* symbols in libc.so.7 to have a __bsd_ prefix.
* Provide .symver compatability with existing 10.x+ binaries that
  referenced the iconv symbols. All existing binaries should work.
* Like on Linux/glibc systems, add a libc_nonshared.a to the ldscript
  at /usr/lib/libc.so.
* Move the "iconv*" wrapper symbols to libc_nonshared.a

This should solve the runtime ambiguity about which symbols resolve
to where.  If you compile against the iconv in libc, your runtime
dependencies will be unambiguous.

Old 9.x libraries and binaries will always resolve against their
libiconv.so.3 like they did on 9.x.  They won't resolve against libc.

Old 10.x binaries will be satisified by the .symver helpers.

This should allow ports to selectively compile against the libiconv
port if needed and it should behave without ambiguity now.

Move the installation of /usr/tests/lib/Kyuafile from src/tests/lib/
to src/lib/.  This is to keep the src/tests/ hierarchy unaware of the
rest of the tree, which makes things clearer in general.  In particular:

1) Everything related to the construction of /usr/tests/lib/ is kept
   in src/lib/.  There is no need to think about different directories
   and how they relate to each other.  (The same applies for libexec,
   usr.bin, etc. but these are not yet handled.)

2) src/tests becomes the place to keep cross-functional test programs

d4a14c8563 Clearly split the logic to build ATF and plain tests apart.
This change introduces a new plain.test.mk file that provides the build
infrastructure to build test programs that don't use any framework.
Most of the code previously in bsd.test.mk moves to plain.test.mk and
atf.test.mk is extended with the missing pieces.

In doing so, this change pushes all test program building logic to the
various *.test.mk files instead of trying to reuse some tiny bits.
In fact, this attempt to reuse some definitions makes the code harder
to read and harder to extend.

The clear benefit of this is that the interface of bsd.test.mk is now
clearly delimited.

318224bbe6 Merge projects/bhyve_npt_pmap into head.
Make the amd64/pmap code aware of nested page table mappings used by bhyve
guests. This allows bhyve to associate each guest with its own vmspace and
deal with nested page faults in the context of that vmspace. This also
enables features like accessed/dirty bit tracking, swapping to disk and
transparent superpage promotions of guest memory.

Guest vmspace:
Each bhyve guest has a unique vmspace to represent the physical memory
allocated to the guest. Each memory segment allocated by the guest is
mapped into the guest's address space via the 'vmspace->vm_map' and is
backed by an object of type OBJT_DEFAULT.

pmap types:
The amd64/pmap now understands two types of pmaps: PT_X86 and PT_EPT.

The PT_X86 pmap type is used by the vmspace associated with the host kernel
as well as user processes executing on the host. The PT_EPT pmap is used by
the vmspace associated with a bhyve guest.

Page Table Entries:
The EPT page table entries as mostly similar in functionality to regular
page table entries although there are some differences in terms of what
bits are used to express that functionality. For e.g. the dirty bit is
represented by bit 9 in the nested PTE as opposed to bit 6 in the regular
x86 PTE. Therefore the bitmask representing the dirty bit is now computed
at runtime based on the type of the pmap. Thus PG_M that was previously a
macro now becomes a local variable that is initialized at runtime using
'pmap_modified_bit(pmap)'.

An additional wrinkle associated with EPT mappings is that older Intel
processors don't have hardware support for tracking accessed/dirty bits in
the PTE. This means that the amd64/pmap code needs to emulate these bits to
provide proper accounting to the VM subsystem. This is achieved by using
the following mapping for EPT entries that need emulation of A/D bits:
               Bit Position           Interpreted By
PG_V               52                 software (accessed bit emulation handler)
PG_RW              53                 software (dirty bit emulation handler)
PG_A               0                  hardware (aka EPT_PG_RD)
PG_M               1                  hardware (aka EPT_PG_WR)

The idea to use the mapping listed above for A/D bit emulation came from
Alan Cox (alc@).

The final difference with respect to x86 PTEs is that some EPT implementations
do not support superpage mappings. This is recorded in the 'pm_flags' field
of the pmap.

TLB invalidation:
The amd64/pmap code has a number of ways to do invalidation of mappings
that may be cached in the TLB: single page, multiple pages in a range or the
entire TLB. All of these funnel into a single EPT invalidation routine called
'pmap_invalidate_ept()'. This routine bumps up the EPT generation number and
sends an IPI to the host cpus that are executing the guest's vcpus. On a
subsequent entry into the guest it will detect that the EPT has changed and
invalidate the mappings from the TLB.

Guest memory access:
Since the guest memory is no longer wired we need to hold the host physical
page that backs the guest physical page before we can access it. The helper
functions 'vm_gpa_hold()/vm_gpa_release()' are available for this purpose.

PCI passthru:
Guest's with PCI passthru devices will wire the entire guest physical address
space. The MMIO BAR associated with the passthru device is backed by a
vm_object of type OBJT_SG. An IOMMU domain is created only for guest's that
have one or more PCI passthru devices attached to them.

Limitations:
There isn't a way to map a guest physical page without execute permissions.
This is because the amd64/pmap code interprets the guest physical mappings as
user mappings since they are numerically below VM_MAXUSER_ADDRESS. Since PG_U
shares the same bit position as EPT_PG_EXECUTE all guest mappings become
automatically executable.

Thanks to Alan Cox and Konstantin Belousov for their rigorous code reviews
as well as their support and encouragement.

Thanks for John Baldwin for reviewing the use of OBJT_SG as the backing
object for pci passthru mmio regions.

Special thanks to Peter Holm for testing the patch on short notice.

7008be5bd7 Change the cap_rights_t type from uint64_t to a structure that we can extend
in the future in a backward compatible (API and ABI) way.

The cap_rights_t represents capability rights. We used to use one bit to
represent one right, but we are running out of spare bits. Currently the new
structure provides place for 114 rights (so 50 more than the previous
cap_rights_t), but it is possible to grow the structure to hold at least 285
rights, although we can make it even larger if 285 rights won't be enough.

The structure definition looks like this:

	struct cap_rights {
		uint64_t	cr_rights[CAP_RIGHTS_VERSION + 2];
	};

The initial CAP_RIGHTS_VERSION is 0.

The top two bits in the first element of the cr_rights[] array contain total
number of elements in the array - 2. This means if those two bits are equal to
0, we have 2 array elements.

The top two bits in all remaining array elements should be 0.
The next five bits in all array elements contain array index. Only one bit is
used and bit position in this five-bits range defines array index. This means
there can be at most five array elements in the future.

To define new right the CAPRIGHT() macro must be used. The macro takes two
arguments - an array index and a bit to set, eg.

	#define	CAP_PDKILL	CAPRIGHT(1, 0x0000000000000800ULL)

We still support aliases that combine few rights, but the rights have to belong
to the same array element, eg:

	#define	CAP_LOOKUP	CAPRIGHT(0, 0x0000000000000400ULL)
	#define	CAP_FCHMOD	CAPRIGHT(0, 0x0000000000002000ULL)

	#define	CAP_FCHMODAT	(CAP_FCHMOD | CAP_LOOKUP)

There is new API to manage the new cap_rights_t structure:

	cap_rights_t *cap_rights_init(cap_rights_t *rights, ...);
	void cap_rights_set(cap_rights_t *rights, ...);
	void cap_rights_clear(cap_rights_t *rights, ...);
	bool cap_rights_is_set(const cap_rights_t *rights, ...);

	bool cap_rights_is_valid(const cap_rights_t *rights);
	void cap_rights_merge(cap_rights_t *dst, const cap_rights_t *src);
	void cap_rights_remove(cap_rights_t *dst, const cap_rights_t *src);
	bool cap_rights_contains(const cap_rights_t *big, const cap_rights_t *little);

Capability rights to the cap_rights_init(), cap_rights_set(),
cap_rights_clear() and cap_rights_is_set() functions are provided by
separating them with commas, eg:

	cap_rights_t rights;

	cap_rights_init(&rights, CAP_READ, CAP_WRITE, CAP_FSTAT);

There is no need to terminate the list of rights, as those functions are
actually macros that take care of the termination, eg:

	#define	cap_rights_set(rights, ...)				\
		__cap_rights_set((rights), __VA_ARGS__, 0ULL)
	void __cap_rights_set(cap_rights_t *rights, ...);

Thanks to using one bit as an array index we can assert in those functions that
there are no two rights belonging to different array elements provided
together. For example this is illegal and will be detected, because CAP_LOOKUP
belongs to element 0 and CAP_PDKILL to element 1:

	cap_rights_init(&rights, CAP_LOOKUP | CAP_PDKILL);

Providing several rights that belongs to the same array's element this way is
correct, but is not advised. It should only be used for aliases definition.

This commit also breaks compatibility with some existing Capsicum system calls,
but I see no other way to do that. This should be fine as Capsicum is still
experimental and this change is not going to 9.x.

865ca149dc system(): Restore behaviour for SIGINT and SIGQUIT.
As mentioned in r16117 and the book "Advanced Programming in the Unix
Environment" by W. Richard Stevens, we should ignore SIGINT and SIGQUIT
before forking, since it is not guaranteed that the parent process starts
running soon enough.

To avoid calling sigaction() in the vforked child, instead block SIGINT and
SIGQUIT before vfork() and keep the sigaction() to ignore after vfork(). The
FreeBSD kernel discards ignored signals, even if they are blocked;
therefore, it is not necessary to unblock SIGINT and SIGQUIT earlier.

e73151eb82 libc: Always use our own copy of sys_errlist and sys_nerr (.so only).
This ensures strerror() and friends continue to work correctly even if a
(non-PIE) executable linked against an older libc imports sys_errlist (which
causes sys_errlist to refer to the executable's copy with a size fixed when
that executable was linked).

The executable's use of sys_errlist remains broken because it uses the
current value of sys_nerr and may access past the bounds of the array.

Different from the message "Using sys_errlist from executables is not
ABI-stable" on freebsd-arch, this change does not affect the static library.
There seems no reason to prevent overriding the error messages in the static
library.

7da1a731c6 Expand the use of stat(2) flags to allow storing some Windows/DOS
and CIFS file attributes as BSD stat(2) flags.

This work is intended to be compatible with ZFS, the Solaris CIFS
server's interaction with ZFS, somewhat compatible with MacOS X,
and of course compatible with Windows.

The Windows attributes that are implemented were chosen based on
the attributes that ZFS already supports.

The summary of the flags is as follows:

UF_SYSTEM:	Command line name: "system" or "usystem"
		ZFS name: XAT_SYSTEM, ZFS_SYSTEM
		Windows: FILE_ATTRIBUTE_SYSTEM

		This flag means that the file is used by the
		operating system.  FreeBSD does not enforce any
		special handling when this flag is set.

UF_SPARSE:	Command line name: "sparse" or "usparse"
		ZFS name: XAT_SPARSE, ZFS_SPARSE
		Windows: FILE_ATTRIBUTE_SPARSE_FILE

		This flag means that the file is sparse.  Although
		ZFS may modify this in some situations, there is
		not generally any special handling for this flag.

UF_OFFLINE:	Command line name: "offline" or "uoffline"
		ZFS name: XAT_OFFLINE, ZFS_OFFLINE
		Windows: FILE_ATTRIBUTE_OFFLINE

		This flag means that the file has been moved to
		offline storage.  FreeBSD does not have any special
		handling for this flag.

UF_REPARSE:	Command line name: "reparse" or "ureparse"
		ZFS name: XAT_REPARSE, ZFS_REPARSE
		Windows: FILE_ATTRIBUTE_REPARSE_POINT

		This flag means that the file is a Windows reparse
		point.  ZFS has special handling code for reparse
		points, but we don't currently have the other
		supporting infrastructure for them.

UF_HIDDEN:	Command line name: "hidden" or "uhidden"
		ZFS name: XAT_HIDDEN, ZFS_HIDDEN
		Windows: FILE_ATTRIBUTE_HIDDEN

		This flag means that the file may be excluded from
		a directory listing if the application honors it.
		FreeBSD has no special handling for this flag.

		The name and bit definition for UF_HIDDEN are
		identical to the definition in MacOS X.

UF_READONLY:	Command line name: "urdonly", "rdonly", "readonly"
		ZFS name: XAT_READONLY, ZFS_READONLY
		Windows: FILE_ATTRIBUTE_READONLY

		This flag means that the file may not written or
		appended, but its attributes may be changed.

		ZFS currently enforces this flag, but Illumos
		developers have discussed disabling enforcement.

		The behavior of this flag is different than MacOS X.
		MacOS X uses UF_IMMUTABLE to represent the DOS
		readonly permission, but that flag has a stronger
		meaning than the semantics of DOS readonly permissions.

UF_ARCHIVE:	Command line name: "uarch", "uarchive"
		ZFS_NAME: XAT_ARCHIVE, ZFS_ARCHIVE
		Windows name: FILE_ATTRIBUTE_ARCHIVE

		The UF_ARCHIVED flag means that the file has changed and
		needs to be archived.  The meaning is same as
		the Windows FILE_ATTRIBUTE_ARCHIVE attribute, and
		the ZFS XAT_ARCHIVE and ZFS_ARCHIVE attribute.

		msdosfs and ZFS have special handling for this flag.
		i.e. they will set it when the file changes.

sys/param.h:		Bump __FreeBSD_version to 1000047 for the
			addition of new stat(2) flags.

chflags.1:		Document the new command line flag names
			(e.g. "system", "hidden") available to the
			user.

ls.1:			Reference chflags(1) for a list of file flags
			and their meanings.

strtofflags.c:		Implement the mapping between the new
			command line flag names and new stat(2)
			flags.

chflags.2:		Document all of the new stat(2) flags, and
			explain the intended behavior in a little
			more detail.  Explain how they map to
			Windows file attributes.

			Different filesystems behave differently
			with respect to flags, so warn the
			application developer to take care when
			using them.

zfs_vnops.c:		Add support for getting and setting the
			UF_ARCHIVE, UF_READONLY, UF_SYSTEM, UF_HIDDEN,
			UF_REPARSE, UF_OFFLINE, and UF_SPARSE flags.

			All of these flags are implemented using
			attributes that ZFS already supports, so
			the on-disk format has not changed.

			ZFS currently doesn't allow setting the
			UF_REPARSE flag, and we don't really have
			the other infrastructure to support reparse
			points.

msdosfs_denode.c,
msdosfs_vnops.c:	Add support for getting and setting
			UF_HIDDEN, UF_SYSTEM and UF_READONLY
			in MSDOSFS.

			It supported SF_ARCHIVED, but this has been
			changed to be UF_ARCHIVE, which has the same
			semantics as the DOS archive attribute instead
			of inverse semantics like SF_ARCHIVED.

			After discussion with Bruce Evans, change
			several things in the msdosfs behavior:

			Use UF_READONLY to indicate whether a file
			is writeable instead of file permissions, but
			don't actually enforce it.

			Refuse to change attributes on the root
			directory, because it is special in FAT
			filesystems, but allow most other attribute
			changes on directories.

			Don't set the archive attribute on a directory
			when its modification time is updated.
			Windows and DOS don't set the archive attribute
			in that scenario, so we are now bug-for-bug
			compatible.

smbfs_node.c,
smbfs_vnops.c:		Add support for UF_HIDDEN, UF_SYSTEM,
			UF_READONLY and UF_ARCHIVE in SMBFS.

			This is similar to changes that Apple has
			made in their version of SMBFS (as of
			smb-583.8, posted on opensource.apple.com),
			but not quite the same.

			We map SMB_FA_READONLY to UF_READONLY,
			because UF_READONLY is intended to match
			the semantics of the DOS readonly flag.
			The MacOS X code maps both UF_IMMUTABLE
			and SF_IMMUTABLE to SMB_FA_READONLY, but
			the immutable flags have stronger meaning
			than the DOS readonly bit.

stat.h:			Add definitions for UF_SYSTEM, UF_SPARSE,
			UF_OFFLINE, UF_REPARSE, UF_ARCHIVE, UF_READONLY
			and UF_HIDDEN.

			The definition of UF_HIDDEN is the same as
			the MacOS X definition.

			Add commented-out definitions of
			UF_COMPRESSED and UF_TRACKED.  They are
			defined in MacOS X (as of 10.8.2), but we
			do not implement them (yet).

ufs_vnops.c:		Add support for getting and setting
			UF_ARCHIVE, UF_HIDDEN, UF_OFFLINE, UF_READONLY,
			UF_REPARSE, UF_SPARSE, and UF_SYSTEM in UFS.
			Alphabetize the flags that are supported.

			These new flags are only stored, UFS does
			not take any action if the flag is set.

5aa60b6f21 Add new mmap(2) flags to permit applications to request specific virtual
address alignment of mappings.
- MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n).
  Requests for n >= number of bits in a pointer or less than the size of
  a page fail with EINVAL.  This matches the API provided by NetBSD.
- MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED.  It can be used
  to optimize the chances of using large pages.  By default it will align
  the mapping on a large page boundary (the system is free to choose any
  large page size to align to that seems best for the mapping request).
  However, if the object being mapped is already using large pages, then
  it will align the virtual mapping to match the existing large pages in
  the object instead.
- Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and
  VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment.
  MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while
  MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE.
- mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than
  explicitly using VMFS_SUPER_SPACE.  All device objects are forced to
  use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively
  equivalent.

88d961f32e libc: Use O_CLOEXEC when writing gmon files (cc -pg). 2013-08-13 21:45:48 +00:00
Peter Wemm
7d1ffcb72a vfork(2) was listed as deprecated in 1994 (r1573) and was the false
reports of its impending demise were removed in 2009 (r199257).

However, in 1996 (r16117) system(3) was switched from vfork(2) to
fork(2) based partly on this.  Switch back to vfork(2).  This has a
dramatic effect in cases of extreme mmap use - such as excessive
abuse (500+) of shared libraries.

popen(3) has used vfork(2) for a while.  vfork(2) isn't going anywhere.

0ff204bbd1 The iconv in libc did two things - implement the standard APIs, the GNU
extensions and also tried to be link time compatible with ports libiconv.
This splits that functionality and enables the parts that shouldn't
interfere with the port by default.

WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.

I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can.  I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc.  If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.

This is an extension of behavior on other system.  iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.

Bumped osreldate.

f9562c1748 Our libc iconv (unlike gnu iconv and the citrus code in NetBSD) has a
bypass mode when src == dst.  Unfortunately, there are tools in ports
that pass byte streams through iconv to determine if the encodings
are valid.  eg: gettext-0.18.3+.

Disable the optimization and behave like the other implementations.

a273027f92 Update Bind to 9.8.5-P2
New Features

   Adds a new configuration option, "check-spf"; valid values are
   "warn" (default) and "ignore".  When set to "warn", checks SPF
   and TXT records in spf format, warning if either resource record
   type occurs without a corresponding record of the other resource
   record type.  [RT #33355]

   Adds support for Uniform Resource Identifier (URI) resource
   records. [RT #23386]

   Adds support for the EUI48 and EUI64 RR types. [RT #33082]

   Adds support for the RFC 6742 ILNP record types (NID, LP, L32,
   and L64). [RT #31836]

Feature Changes

   Changes timing of when slave zones send NOTIFY messages after
   loading a new copy of the zone.  They now send the NOTIFY before
   writing the zone data to disk.  This will result in quicker
   propagation of updates in multi-level server structures. [RT #27242]
   "named -V" can now report a source ID string.  (This is will be
   of most interest to developers and troubleshooters).  The source

   ID for ISC's production versions of BIND is defined in the "srcid"
   file in the build tree and is normally set to the most recent
   git hash. [RT #31494]

   Response Policy Zone performance enhancements.  New "response-policy"
   option "min-ns-dots".  "nsip" and "nsdname" now enabled by default
   with RPZ. [RT #32251]

but ACM formula we use have internal state (and return value) in the
[1, 0x7ffffffe] range, so our RAND_MAX (0x7fffffff) is never reached
because it is off by one, zero is not reached too.

Correct both RAND_MAX and rand(3) return value, shifting last one
to the 0 by 1 subtracted, resulting POSIXed [0, 0x7ffffffd(=new RAND_MAX)]
range.

fc03d22b17 Refine UMA bucket allocation to reduce space consumption and improve
performance.

 - Always free to the alloc bucket if there is space.  This gives LIFO
   allocation order to improve hot-cache performance.  This also allows
   for zones with a single bucket per-cpu rather than a pair if the entire
   working set fits in one bucket.
 - Enable per-cpu caches of buckets.  To prevent recursive bucket
   allocation one bucket zone still has per-cpu caches disabled.
 - Pick the initial bucket size based on a table driven maximum size
   per-bucket rather than the number of items per-page.  This gives
   more sane initial sizes.
 - Only grow the bucket size when we face contention on the zone lock, this
   causes bucket sizes to grow more slowly.
 - Adjust the number of items per-bucket to account for the header space.
   This packs the buckets more efficiently per-page while making them
   not quite powers of two.
 - Eliminate the per-zone free bucket list.  Always return buckets back
   to the bucket zone.  This ensures that as zones grow into larger
   bucket sizes they eventually discard the smaller sizes.  It persists
   fewer buckets in the system.  The locking is slightly trickier.
 - Only switch buckets in zalloc, not zfree, this eliminates pathological
   cases where we ping-pong between two buckets.
 - Ensure that the thread that fills a new bucket gets to allocate from
   it to give a better upper bound on allocation time.
