a59d6a8724 Implementing 'fallback' nsswitch source. 'fallback' source is used
when particular function can't be found in nsswitch-module. For
example, getgrouplist(3) will use module-supplied 'getgroupmembership'
function (which can work in an optimal way for such source as LDAP) and
will fall back to the stanard iterate-through-all-groups implementation
otherwise.

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.

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.

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.

in include/machine/.

2966d28c32 Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

772ad651bf Update the dump program to save extended attributes. Update
the restore program to restore all dumped extended attributes.

If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.

The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.

This resolves PR 93085 which will be closed once the code
has been MFC'ed.

Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

9e1ea8f2fe Attempt to improve application portability by marking `struct ar_hdr'
as `packed'.

The C standard leaves the alignment of individual members of a C
struct upto the implementation, so pedantically speaking portable
code cannot assume that the layout of a `struct ar_hdr' in memory
will match its layout in a file.  Using a __packed attribute
declaration forces file and memory layouts for this structure to
match.

04c7da702f A GEOM cache can speed up read performance by sending fixed size
read requests to its consumer.  It has been developed to address
the problem of a horrible read performance of a 64k blocksize FS
residing on a RAID3 array with 8 data components, where a single
disk component would only get 8k read requests, thus effectively
killing disk performance under high load.  Documentation will be
provided later.  I'd like to thank Vsevolod Lobko for his bright
ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug.
