83804ea074 The fallback flag in nsdispatch prevents the fallback implementation of
getgroupmembership() from invoking the correct backend in the compat case.
Replace it with a nesting depth counter so it only blocks one level (the
first is the group -> group_compat translation, the second is the actual
backend).  This is one of two bugs that break getgrouplist() in the compat
case, the second being that the backend's own getgroupmembership() method
is ignored.  Unfortunately, that is not easily fixable without a redesign
of our nss implementation (which is also needed to implement the +@group
syntax in /etc/passwd).

f53b045631 Eliminate conf_lock and instead rely on the NSS write lock to protect
NSS configuration state.

As a side effect, this fixes a race condition which can occur if multiple
threads call nsdispatch(3) concurrently before nsswitch.conf has been
parsed. Previously, the thread holding conf_lock could cause other threads
to return from nss_configure() before nsswitch.conf had been parsed, forcing
them to fall back to the default sources for their NSS methods.

53e1ffbbce The current POSIX semaphore implementation stores the _has_waiters flag
in a separate word from the _count.  This does not permit both items to
be updated atomically in a portable manner.  As a result, sem_post()
must always perform a system call to safely clear _has_waiters.

This change removes the _has_waiters field and instead uses the high bit
of _count as the _has_waiters flag.  A new umtx object type (_usem2) and
two new umtx operations are added (SEM_WAIT2 and SEM_WAKE2) to implement
these semantics.  The older operations are still supported under the
COMPAT_FREEBSD9/10 options.  The POSIX semaphore API in libc has
been updated to use the new implementation.  Note that the new
implementation is not compatible with the previous implementation.
However, this only affects static binaries (which cannot be helped by
symbol versioning).  Binaries using a dynamic libc will continue to work
fine.  SEM_MAGIC has been bumped so that mismatched binaries will error
rather than corrupting a shared semaphore.  In addition, a padding field
has been added to sem_t so that it remains the same size.

can be compiled with libnetbsd without having to invent ad hoc #define's, or
having to convert things over to FreeBSD idioms

b55e8e6e0d My previous commit exposed an issue as it fixed a different
issue. lib/atf isn't a prereq_lib, since it isn't required for other
libraries to build. Remove it. The old kludge of always building it
had effectively been retired. Since we don't want to build the
libraries with the tests when we're bootstrapping, invent
MK_TESTS_SUPPORT which normally defaults to the current MK_TESTS
value, except when explicitly defined. Make lib/atf depend on it being
yes. When building the libraries set MK_TESTS to no, and
MK_TESTS_SUPPORT to the current value of MK_TESTS so that later stages
of the build work correctly. This should fix (and does for me)
people's issues with parallel builds racing between lib/atf and
libexec/atf. Since lib/atf is built during the libraries phase, the
race disappears.

58c47a70a3 Allow libkvm to get the kernel va to pa delta without the need for
physaddr. This should allow for a kernel where PHYSADDR and KERNPHYSADDR
are both undefined.

For now libkvm will use the old method of reading physaddr and kernaddr
to allow it to work with old kernels. This could be removed in the future
when enough time has passed.

a4e4b355f4 The value small=2**-(p+3), where p is the precision, can be determine from
lgamma(x) = -log(x) - log(1+x) + x*(1-g) + x**2*P(x) with g = 0.57...
being the Euler constant and P(x) a polynomial.  Substitution of small
into the RHS shows that the last 3 terms are negligible in comparison to
the leading term.  The choice of 3 may be conservative.

The value large=2**(p+3) is detemined from Stirling's approximation
lgamma(x) = x*(log(x)-1) - log(x)/2 + log(2*pi)/2 + P(1/x)/x
Again, substitution of large into the RHS reveals the last 3 terms
are negligible in comparison to the leading term.

Move the x=+-0 special case into the |x|<small block.

In the ld80 and ld128 implementaion, use fdlibm compatible comparisons
involving ix, lx, and llx.  This replaces several floating point
comparisons (some involving fabsl()) and also fixes the special cases
x=1 and x=2.

41da933c87 Hook up support for userland CTF support in DTrace. This required some
modifications to libproc to support fetching the CTF info for a given file.

With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.

The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.

Add support for the missing POSIX-2001 %U and %W features: the

Initial support for the feature was written by Paul Green.

Major credit goes to Andrey Chernov for detecting much of the
brokenness, and rewriting/cleaning most of the code, making it
much more robust.

c3d1e48a6b Always seek back to the beginning of a regular directory, even if the
previous seek location was 0.  Without this, readdir() would see
dd_loc of zero and call getdirentries() which would start reading
entries at the current seek location of the directory ignoring the
first batch of entries.  Also, rewinddir() should always seek so that
it reads the directory from the beginning to get updated entries.

This change extends all of the functions present in the <pthread.h> and

- Locking a function twice,
- Unlocking a function without a mutex being locked,
- Forgetting to unlock a mutex before returning,
- Destroying or reinitializing a mutex that is currenty locked,
- Using an unlocked mutex in combination with a condition variable.

5608fd23c2 Revert r267233 for now. PIE support needs to be reworked.
1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
   build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
   where it never would work anyhow, such as csu or loader. This suggests
   there may be better ways of adding support to the tree. Many of these
   cases can be fixed such that -fPIE will work but there is really no
   reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
   really building libraries but have been using bsd.prog.mk because the code
   is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
   been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

e9759f8bd3 Add pkgfs, a file system implementation for reading files out of a
compressed tarball, aka package. The file system assumes that the
files are layed-out in the same order as needed to allow for the
package to be streamed. As such, it does not read an entire package
into memory first.

Some properties of the file system:
o   Files that start with '+' are silently skipped. These are found
    in FreeBSD package files.
o   Files smaller than or equal to 4KB will be cached in memory and
    as such allow for some flexibility in accessing files out of
    order.
o   Files with the .tgz suffix are assumed to be (sub-)packages and
    signal the end for a directory scan.

f2fb1d4531 Provide a means for loaders to control which file system to use. This
to counteract the default behaviour of always trying each and every
file system until one succeeds, or the open fails. The problem with the
loader is that we've implemented features based on this behavior. The
handling of compressed files is a good example of this. However, it is
in general highly undesirable to not have a one-time probe (or taste
in the geom lingo), followed by something similar to a mount whenever
we (first) read from a device. Everytime we go to the same device, we
can reasonably assume it (still) has the same file system. For file
systems that need to do far more that a trivial read of a super block,
not having something similar to a mount operation is disastrous from
a performance (and thus usability) perspective.

But, again, since we've implemented features based on this stateless
approach, things can get complicated quickly if and when we want to
change this. And yet, we sometimes do need stateful behaviour.

For this reason, this change simply introduces exclusive_file_system.
When set to the fsops of the file system to use, the open call will
only try this file system. Setting it to NULL restores the default
behaviour. It's a low-cost (low-brow?) approach to provide enough
control without re-implementing the guts of the loader.

A good example of when this is useful is when we're trying to load
files out of a container (say, a software packaga) that itself lives
on a file system or is fetched over the network. While opening the
container can be done in the normal stateless manner, once it is
opened, subsequent opens should only consider the container.

02b6306fb0 In r232153, libarchive 3.0.3 was imported, replacing the archive_hash.h
header with archive_crypto_private.h, and its ARCHIVE_HASH_xxx macros
were renamed to ARCHIVE_CRYPTO_xxx.

Rename these macros in lib/libarchive/config_freebsd.h, to re-enable the
hashes for libarchive again.  This affects the mtree format writer, and
the xar format reader and writer modules.

This also requires changes in the library order for statically linking
rescue, otherwise ld would complain about redefined symbols.  Thanks to
jkim for pointing out the solution.

5f48d8fc26 libstand's qdivrem.c assumes that sizeof(int) == sizeof(long), this is not
true on amd64 I'm not quite positive this is the "correct" solution for
this but it does seem to compile and shut up the spew of warnings when
compiling libstand for userboot.

Add two _Static_asserts() so that in the future somebody will get a compile
failure if an architecture develops that violates the assumptions of this
code. (strongly suggested by jmg)

Change commetns to indicate int types instead of long.  (noted by ian in

d37f2adb38 Fix fault injection in bhyve.
The faulting instruction needs to be restarted when the exception handler
is done handling the fault. bhyve now does this correctly by setting
'vmexit[vcpu].inst_length' to zero so the %rip is not advanced.

A minor complication is that the fault injection APIs are used by instruction
emulation code that is shared by vmm.ko and bhyve. Thus the argument that
refers to 'struct vm *' in kernel or 'struct vmctx *' in userspace needs to
be loosely typed as a 'void *'.

-no escape character means no escaped characters

modify the previous fix so that no pointless realloc()s are done in

to make the logics obvious

fparseln is now part of libc in NetBSD so this changes the previous

e19f362e28 Fix hdestroy() compliance issue.
The hcreate(3) implementation and related functions we inherited
from NetBSD used to free() the key value, something that is not
supported by the standard implementation.

This would cause a segmentation fault when attempting to run
the examples from the opengroup and linux manpages.  NetBSD
has added non-standard calls to provide the previous
behaviour but hdestroy is not very commonly used so at this
time it seems excessive to bring those to FreeBSD.

Bump the __FreeBSD_version as this is an ABI change.

677a88cec2 Add dl_unwind_find_exidx() for ARM EABI, required for C++ exception
handling.  For statically linked apps this uses the __exidx_start/end
symbols set up by the linker.  For dynamically linked apps it finds the
shared object that contains the given address and returns the location and
size of the exidx section in that shared object.

The dl_unwind_find_exidx() name is used by other BSD projects and Android,
and is mentioned in clang 3.5 comments as "the BSD interface" for finding
exidx data.  GCC (in libgcc_s) expects the exact same API and functionality
to be provided by a function named __gnu_Unwind_Find_exidx(), so we provide
that with an alias ("strong reference").

091d453222 Handle nested exceptions in bhyve.
A nested exception condition arises when a second exception is triggered while
delivering the first exception. Most nested exceptions can be handled serially
but some are converted into a double fault. If an exception is generated during
delivery of a double fault then the virtual machine shuts down as a result of
a triple fault.

vm_exit_intinfo() is used to record that a VM-exit happened while an event was
being delivered through the IDT. If an exception is triggered while handling
the VM-exit it will be treated like a nested exception.

vm_entry_intinfo() is used by processor-specific code to get the event to be
injected into the guest on the next VM-entry. This function is responsible for
deciding the disposition of nested exceptions.
