The call is technically in a loop, and under certain circumstances
(which are quite difficult to reproduce in a test case), alloca
can be invoked repeatedly during a single call to clntudp_call.
As a result, the available stack space can be exhausted (even
though individual alloca sizes are bounded implicitly by what
can fit into a UDP packet, as a side effect of the earlier
successful send operation).
This avoids aliasing issues with GCC 6 in -fno-strict-aliasing
mode. (With implicit padding, not all data is copied.)
This change makes it explicit that struct sockaddr_storage is
only 126 bytes large on m68k (unlike elsewhere, where we end up
with the requested 128 bytes). The new test case makes sure that
this does not happen on other architectures.
The conform/ test of limits.h namespace for XPG3 was failing because
of NL_* and NZERO defines. Those symbols are EX-shaded, not
UX-shaded, so it's correct for them to be defined for XPG3; this patch
corrects the expectations accordingly. (Actually it looks like they
should not be listed as optional for these standards, but that's
another matter.)

This patch updates sysdeps/unix/sysv/linux/bits/socket.h for new
constants added in Linux 4.6. AF_KCM / PF_KCM are added. SOL_KCM is
new, and I added a lot of SOL_* values postdating the last one present
in the header, since I saw no apparent reason for the set in glibc to
stop at SOL_IRDA. MSG_BATCH is added; Linux also has
MSG_SENDPAGE_NOTLAST which is not in glibc, but given the comment
starts "sendpage() internal" I presume it's correct for it not to be
in glibc.
(Note that this is a case where the Linux kernel header with userspace
relevant values is *not* a uapi header but include/linux/socket.h - I
don't know why, but at least this header, as well as uapi headers,
needs reviewing for glibc-relevant changes each release.)

ldbl-128ibm had an implementation of fmal that just did (x * y) + z in
most cases, with no attempt at actually being a fused operation.
This patch replaces it with a genuine fused operation. It is not
necessarily correctly rounding, but should produce a result at least
as accurate as the long double arithmetic operations in libgcc, which
I think is all that can reasonably be expected for such a non-IEEE
format where arithmetic is approximate rather than rounded according
to any particular rule for determining the exact result. Like the
libgcc arithmetic, it may produce spurious overflow and underflow
results, and it falls back to the libgcc multiplication in the case of
(finite, finite, zero).
This concludes the fixes for bug 13304; any subsequently found fma
issues should go in separate Bugzilla bugs. Various other pieces of
bug 13304 were fixed in past releases over the past several years.

The testcase tst-cancel[x]17 ends sometimes with a segmentation fault.
This happens in one of 10000 cases. Then the real testcase has already
exited with success and returned from do_test(). The segmentation fault
occurs after returning from main in _dl_fini().
In those cases, the aio_read(&a) was not canceled because the read
request was already in progress. In the meanwhile aio_write(ap) wrote
something to the pipe and the read request is able to read the
requested byte.
The read request hasn't finished before returning from do_test().
After it finishes, it writes the return value and error code from the
read syscall to the struct aiocb a, which lies on the stack of do_test.
The stack of the subsequent function call of _dl_fini or _dl_sort_fini,
which is inlined in _dl_fini is corrupted.
In case of S390, it reads a zero and decrements it by 1:
unsigned int k = nmaps - 1;
struct link_map **runp = maps[k]->l_initfini;
The load from unmapped memory leads to the segmentation fault.
The stack corruption also happens on other architectures.
I saw them e.g. on x86 and ppc, too.
This patch adds an aio_suspend call to ensure, that the read request
is finished before returning from do_test().
ChangeLog:
* nptl/tst-cancel17.c (do_test): Wait for finishing aio_read(&a).
The first SIGUSR1 signal could arrive when sigusr1_sender_pid
was still 0. As a result, kill would send SIGSTOP to the
entire process group. This would cause the test to hang before
printing any output.
This commit also adds a sched_yield to the signal source, so that
it does not flood the parent process with signals it has never a
chance to handle.
Even with these changes, tst-mallocfork2 still fails reliably
after the fix in commit commit 56290d6e76
(Increase fork signal safety for single-threaded processes) is
backed out.

This will allow us to change many aspects of the malloc implementation
while preserving compatibility with existing Emacs binaries.
As a result, existing Emacs binaries will have a larger RSS, and Emacs
needs a few more milliseconds to start. This overhead is specific
to Emacs (and will go away once Emacs switches to its internal malloc).
The new checks to make free and realloc compatible with the dumped heap
are confined to the mmap paths, which are already quite slow due to the
munmap overhead.
This commit weakens some security checks, but only for heap pointers
in the dumped main arena. By default, this area is empty, so those
checks are as effective as before.

The conform/ tests for fcntl.h are failing for XPG3 and XPG4 because
of missing S_IFSOCK.
This is a case of a bogus test. The relevant wording requiring such
constants is, in current POSIX (and this requirement dates back as far
as XPG4), "The <fcntl.h> header shall define the symbolic constants
for file modes for use as values of mode_t as described in
<sys/stat.h>.". Note that this is *file modes* not *file types*.
That makes sense, since the point is presumably for use with functions
such as open that are declared in fcntl.h, where file modes are
relevant but file types aren't. So this patch removes all those
spurious S_IF* expectations for fcntl.h (the macros are generally
still *allowed* through the permission to make everything from
sys/stat.h visible).

This provides a band-aid and addresses the scenario where fork is
called from a signal handler while the process is in the malloc
subsystem (or has acquired the libio list lock). It does not
address the general issue of async-signal-safety of fork;
multi-threaded processes are not covered, and some glibc
subsystems have fork handlers which are not async-signal-safe.
