59fac1825f On 4.X it was possible for an application to initialise a local FILE
structure and call stdio functions. In 5.X this was broken when FILE
locking was introduced into libc.

This change makes most (relevant) stdio functions work again when the
_extra file in FILE isn't initialised (and can't be without a libc
function to do it since the __sFILEX structure is private to libc).

16fc3635f7 Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

33dee81933 Make the resolver(3) and many associated interfaces much more reentrant.
The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now
with what should be totally reentrant, and h_errno values will now
be preserved correctly, but this does not affect interfaces such as
gethostbyname(3) which are still mostly non-reentrant.

In all of these relevant functions, the thread-safety has been pushed
down as far as it seems possible right now.  This means that operations
that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected
still under global locks that getaddrinfo(3) defines, but where possible
the locking is greatly reduced.  The most noticeable improvement is
that multiple DNS lookups can now be run at the same time, and this
shows major improvement in performance of DNS-lookup threaded programs,
and solves the "Mozilla tab serialization" problem.

No single-threaded applications need to be recompiled.  Multi-threaded
applications that reference "_res" to change resolver(3) options will
need to be recompiled, and ones which reference "h_errno" will also
if they desire the correct h_errno values.  If the applications already
understood that _res and h_errno were not thread-safe and had their own
locking, they will see no performance improvement but will not
actually break in any way.

Please note that when NSS modules are used, or when nsdispatch(3)
defaults to adding any lookups of its own to the individual libc
_nsdispatch() calls, those MUST be reentrant as well.

5c70dac879 Modify the implementation of libc semaphores so that they can be

The libc version of semaphores always uses kernel semaphores
regardless of whether pshared is set or not.  When threads are
not present, it is difficult to get sem_wait() or sem_timedwait()
to do the right thing (since pthread_cond_timedwait() and
pthread_cond_wait() are stubs in libc and just return immediately).

ccfddc1cce Clarify the behavior of ptrace(2) a little bit: the tracing process
must first attach to the traced process.  If the tracing process
exits without detaching, the traced process will be killed rather
than continued.  For the duration of the tracing session, the traced
process is reparented to the tracing process (with resulting expected
behaviors).  It is permissible to trace more than one other process

c849849d06 It was reported that when using nss_ldap, getgrent(3) would behave
incorrectly when encountering `large' groups (many members and/or many
long member names).  The reporter tracked this down to the glibc NSS
module compatibility code (nss_compat.c): it would prematurely record
that a NSS module was finished iterating through its database in some
cases.

Two aspects are corrected:

1. nss_compat.c recorded that a NSS module was finished iterating
   whenever the module reported something other than SUCCESS.  The
   correct logic is to continue iteration when the module reports
   either SUCCESS or RETURN.  The __nss_compat_getgrent_r and
   __nss_compat_getpwent_r routines are updated to reflect this.

2. An internal helper macro __nss_compat_result is used to map glibc
   NSS status codes to BSD NSS status codes (e.g. NSS_STATUS_SUCCESS ->
   NS_SUCCESS).  It provided the obvious mapping.

   When a NSS routine is called with a too-small buffer, the
   convention in the BSD NSS code is to report RETURN.  (This is used
   to implement reentrant APIs such as getpwnam_r(3).)  However, the
   convention in glibc for this case is to set errno = ERANGE and
   overload TRYAGAIN.  __nss_compat_result is updated to handle this
   case.

04cb6b3aa6 "Fix" makecontext() so that the C code begins execution with its
ABI-required stack alignment.  C code expects that the push of the
return address disturbed the 16 byte alignment and it will take corrective
measures to fix it before making another call.  Of course, if its wrong
to start with, then all hell breaks loose.  Essentially we "fix" this
by making the stack alignment odd to start with.

This was one of the things that broke on libkse with apps that use
floating point/varargs/etc.

fd7707aa50 Do not adjust to the pagesize at runtime. Besides for the one-time
initialization overhead, there's a problem in that we never call
imalloc() and thus malloc_init() for zero-sized allocations. As a
result, malloc(0) returns NULL when it's the first or only malloc in
the program. Any non-zero allocation will initialize the malloc code
with the side-effect that subsequent zero-sized allocations return a
non-NULL pointer. This is because the pointer we return for zero-
sized allocations is calculated from malloc_pageshift, which needs
to be initialized at runtime on ia64.

The result of the inconsistent behaviour described above is that
configure scripts failed the test for a GNU compatible malloc. This
resulted in a lot of broken ports.

Other, even simpler, solutions were possible as well:
1.  initialize malloc_pageshift with some non-zero value (say 13 for
    8KB pages) and keep the runtime adjustment.
2.  Stop using malloc_pageshift to calculate ZEROSIZEPTR.

Removal of the runtime adjustment was chosen because then ia64 is the
same as any other platform. It is not to say that using a page size
obtained at runtime is bad per se. It's that there's currently a high
level of gratuity for its existence and the moment it causes problems
is the moment you need to get rid of it. Hence, it's not unthinkable
that this commit is (partially) reverted some time in the future when
we do have a good reason for it and a good way to achieve it.

encodings, we will pass in a pointer to the file's mbstate_t object, and
only zero it at the time the file gets opened.

d4f6cd06dd Allow mbrtowc() and wcrtomb() to be implemented directly, instead of
as wrappers around the deprecated 4.4BSD rune functions. This paves the
way for state-dependent encodings, which the rune API does not support.
- Add __emulated_sgetrune() and __emulated_sputrune(), which are
  implementations of sgetrune() and sputrune() in terms of
  mbrtowc() and wcrtomb().
- Rename the old rune-wrapper mbrtowc() and wcrtomb() functions to
  __emulated_mbrtowc() and __emulated_wcrtomb().
- Add __mbrtowc and __wcrtomb function pointers, which point to the
  current locale's conversion functions, or the __emulated versions.
- Implement mbrtowc() and wcrtomb() as calls to these function pointers.
- Make the "NONE" encoding implement mbrtowc() and wcrtomb() directly.

All of this emulation mess will be removed, together with rune support,
in FreeBSD 6.

b32428bbc5 The FP status register allows for 6 traps to be masked. One of them,
the denormal/unnormal trap, is not a standard IEEE trap. We did
not exclude it from being returned by fpgetmask(), nor did we make
sure that fpsetmask() didn't clobber it. Since the non-IEEE trap
is not part of fp_except_t, users of ifpgetmask()/fpsetmask() would
be confronted with unexpected behaviour, one of which is a SIGFPE
for denormal/unnormal FP results.

This commit makes sure that we don't leak the denormal/unnormal mask

6046bc37e8 Make getcontext(2) work on i386. It needs a small wrapper in libc
otherwise the return from the syscall stub for getcontext will pop off
the return value for the caller to the getcontext stub and it will appear
as though the setcontext() syscall returned instead of the getcontext().
The same bug exists on amd64, a fix is coming there too.

The bug can be demonstrated with this test code fragment:
main()
{
        ucontext_t top;

        if (getcontext(&top) == 0) {
                write(2, "PING!\n", 6);

738824ad6c As new objects begin to support new labels, start to generalize
the default label support in /etc/mac.conf.  Rather than maintain
each default label type in an explicit global variable in mac.c,
keep a list of defaults loaded from the configuration file.
Generalize the parsing so that we support both the older:

        default_file_labels foo
        default_ifnet_labels foo
        default_process_labels foo

And also a new:

        default_labels file foo
        default_labels ifnet foo
        default_labels process foo

We now accept arbitrary object classes in the first argument.  If
the same object is specified more than once, we discard the
earlier definition in favor of the later one.

Add a new API, mac_prepare_type(), which accepts a mac_t to
prepare, as well as an object name in the second argument, which
will pull a default label set for the object out of the
configuration loaded by mac_init_internal().  This permits the libc
to adapt to new objects known about by applications but not by libc
at compile-time.

Also liberalize the error handling a bit: if we're using implicit
initialization (i.e., the application didn't explicitly initialize
the MAC code), ignore syntax errors and only use valid lines.  In
the future, we may want to add explicit warnings and do this a
bit more consistently.

While here, add support for a MAC_CONFFILE environmental variable,
which may be used to specify an alternative mac.conf configuration
file if the application isn't running with modified privilege
(issetugid()).

argument were already broken, since the same type conversion was done
by the old implementation.  Add a note in the Makefile so that whoever

effcb5eca3 Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEM
when the buffer is not long enough to hold the current host name.
POSIX does not standardize error returns for gethostname(), so it
doesn't matter which one we use, but ENAMETOOLONG is at least a little
more intuitive, and mi suggests the existence of prior art.  I've been
running with this change for a while on my home machine with no
effect.  At the same time, I've updated the prototype for
gethostname() to use the correct standard type (size_t) for the
namelen argument.

All of the in-tree callers fall into one of the following categories:
1) Call perror() or equivalent when gethostname() fails.
2) Ignore gethostname()'s return value entirely, potentially resulting
in data corruption if the buffer is too small.
3) Fall back to a (possibly sensible) default value if gethostname()
fails.

Many of the callers I examined shows signs of confusion about the
correct sizing of the host name buffer.  gethostname(3) now has more
information about this, as well as updated standards information.

- All those diffs to syscalls.master for each architecture *are*
   necessary. This needed clarification; the stub code generation for
   mlockall() was disabled, which would prevent applications from
   linking to this API (suggested by mux)
 - Giant has been quoshed. It is no longer held by the code, as
   the required locking has been pushed down within vm_map.c.
 - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES
   to express their intention explicitly.
 - Inspected at the vmstat, top and vm pager sysctl stats level.
   Paging-in activity is occurring correctly, using a test harness.
 - The RES size for a process may appear to be greater than its SIZE.
   This is believed to be due to mappings of the same shared library
   page being wired twice. Further exploration is needed.

03bab8d60f o There are 6 trap disable bits in ar.fpsr, not five. Even though we
didn't provide a constant for one of them (non-IEEE denormal trap),
  in an attempt to not support it probably, it's not we are left with
  the lower 5 bits.
o Properly mask the passed or returned fp_except_t. Not doing so
  causes instant core dumps by trying to write an invalid value to
  ar.fpsr. Now that we're masking, stop using exclusive-or to invert
  bits.

This fixes the illegal instruction fault encountered when building
mozilla.

o  uuid_compare(3) is specified to return -1, 0 or 1, depending on

8955f59879 Override the default stubs for getcontext(2) and swapcontext(2) so
that we can flush the register stack prior to entering the kernel.
This avoids having dirty registers and saves us from having to
manually write them to the backing store from within the kernel.
In that respect, flushing the RSE is both functionally required as
well as performance optimal.

On average we had 18 dirty registers when getcontext(2) was called
from libthr. Since libthr does not switch back to a context created
by getcontext(2), not having dealt with the dirty registers was
harmless.

55e24f6e77 Document an additional error return value. The connect(2) call can also
return EACCES on non-Unix domain sockets as demonstrated by the
following program:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int
main(int argc, char *argv[])
{
	struct sockaddr_in rem_addr;
	int sock;

	if ((sock = socket(AF_INET, SOCK_STREAM, 0)) < 0) {
		perror("socket");
		exit(1);
	}

	bzero((char *)&rem_addr, sizeof(rem_addr));
	rem_addr.sin_family = AF_INET;
	rem_addr.sin_addr.s_addr = INADDR_NONE;
	rem_addr.sin_port = htons(10000);

	if (connect(sock, (struct sockaddr *)&rem_addr,
sizeof(rem_addr)) < 0) {
		perror("connect");
		exit(1);
	}
}

The call chain returning this value is probably:

kern/uipc_syscalls.c:connect
kern/uipc_socket.c:soconnect
netinet/tcp_usrreq.c:tcp_usr_connect
netinet/tcp_output.c:tcp_output
netinet/ip_output.c:ip_output

0287aa1cee Revert to using yp_order() to probe for master.paswd.by* maps and
don't probe the server at all for passwd.by* maps. This fixes
interoperability with the Services For UNIX NIS server (which is
really a front end to Captive^WActiveDirectory). This server
incorrectly returns success for all YPPROC_MASTER requests,
even for maps that don't exist, which makes it impossible to
(ab)use it to probe for the existence of the master.passwd.by*
maps.

This is a little kludgey, but basically restores the original
behavior of getpwent.c as it is in -stable, and works around both
the lack of YPPROC_ORDER on NIS+ servers as well as the broken
YPPROC_MASTER on Services For UNIX servers.
