8074e24dce The previous commit changed the behavior of nsdispatch() in the
case where an /etc/nsswitch.conf file was present, but could not
be opened (e.g. due to permissions).  Previously, the open failure
condition was suppressed, and the built-in defaults were used.  In
revision 1.11, however, propagated the open failure causing all
nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs
including getpwnam and gethostbyname unconditionally failed.

This commit restores the previous behavior.

3726033348 Fix Yet Another 16 byte stack alignment bug. Thankfully, this one is
solved by a simple 'make world'.  The signalcontext function was going
to the trouble of generating an even 16 byte alignment, but in fact it
needed to be odd aligned to simulate the 8-byte return address having
been pushed by the caller.  This fixes yet another group of crashes in
applications using libpthread.  And yet again, it was my fault all along.

While here, rename the duplicate internal ctx_wrapper() functions to
makectx_wrapper() and sigctx_wrapper() so that traces aren't ambiguous.

a03fd3b656 When a dynamic NSS module is built and linked against a thread
library, it may pull in that thread library at run time.  If the
process started out single-threaded, this could cause attempts to
release locks that do not exist.  Guard against this possibility by
checking __isthreaded before invoking thread primitives.

A similar problem remains if the process is linked against one thread
library, but the NSS module is linked against another.  This can only
be avoided by careful design of the NSS module.

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

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
overridden by the threads library to provide a userland version
of non-pshared semaphores and cancellation points.  Also add
a sem_timedwait().

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
at a time.  When using waitpid() to monitor the behavior of the traced
process, signals are intercepted: they may optionally then be
forwarded using ptrace().  Signals are generated normally by and for
the process, but also by the tracing facility (SIGTRAP).

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

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.

was rejected as a range error, while any values less than LONG_MIN
were silently substituted with LONG_MIN.  Furthermore, on some
platforms `time_t' has less range than `long' (e.g. alpha), which may
give incorrect results when parsing some strings.

920325ee1d Implement mac_get_peer(3) using getsockopt() with SOL_SOCKET and
SO_PEERLABEL.  This provides an interface to query the label of a
socket peer without embedding implementation details of mac_t in
the application.  Previously, sizeof(*mac_t) had to be specified
by an application when performing getsockopt().

Document mac_get_peer(3), and expand documentation of the other
mac_get(3) functions.  Note that it's possible to get EINVAL back
from mac_get_fd(3) when pointing it at an inappropriate object.

NOTE: mac_get_fd() and mac_set_fd() support for sockets will
follow shortly, so the documentation is slightly ahead of the
code.

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.
