 [patch] hppa: make __sigrtmin 32 (abi break).

In the Linux kernel version 3.17 the signal numbers were rearranged in
order to make hppa like every other arch. Previously we started
__SIGRTMIN at 37, and that meant several pieces of important software,
including systemd, would fail to build. To support systemd we removed
SIGEMT and SIGLOST, and rearranged the others according to expected
values. This is technically an ABI incompatible change, but because
zero applications use SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS nothing
broke.  Nothing uses SIGEMT and SIGLOST, and they were present for
HPUX compatibility which is no longer supported. Thus because nothing
breaks we don't do any compatibility work here.

Upstream kernel commit is 1f25df2eff5b25f52c139d3ff31bc883eee9a0ab.

 [patch] the critical section lock _can_ be held in these place.

At least since hurd_thread_cancel can be called by another thread and lock our
critical lock.

http://bugs.debian.org/46859


Thomas suggested that there is no need to take the critical section
lock.  I believe that taking the critical section lock is necessary to
prevent the target thread from entering a signal handler.  Roland will
look into the problem.


Taking the critical section lock makes these assertions bogus.

It happens that hurd_thread_cancel is only called from libports and inside
/hurd/term so this is rare in practice.

A reproducer can be found here:

 [patch] global signal dispositions.

Although they should not change the
default behaviors of signals for cthread programs, these patches add
new functions which can be used by libpthread to enable
POSIX-conforming behavior of signals on a per-thread basis.

YYYY-MM-DD  Jeremie Koenig  <jk@jk.fr.eu.org>

    e407ae3 Hurd signals: implement global signal dispositions
    38eb4b3 Hurd signals: provide a sigstate destructor
    344dfd6 Hurd signals: fix sigwait() for global signals
    fb055f2 Hurd signals: fix global untraced signals.

YYYY-MM-DD  Thomas Schwinge  <thomas@codesourcery.com>

	* sysdeps/mach/hurd/fork.c (__fork): In the child, reinitialize
	the global sigstate's lock.

This is work in progress.

This cures an issue that would very rarely cause a deadlock in the child
in fork, tries to unlock ss' critical section lock at the end of fork.
This will typically (always?) be observed in /bin/sh, which is not
surprising as that is the foremost caller of fork.

To reproduce an intermediate state, add an endless loop if
_hurd_global_sigstate is locked after __proc_dostop (cast through
volatile); that is, while still being in the fork's parent process.

When that triggers (use the libtool testsuite), the signal thread has
already locked ss (which is _hurd_global_sigstate), and is stuck at
hurdsig.c:685 in post_signal, trying to lock _hurd_siglock (which the
main thread already has locked and keeps locked until after
__task_create).  This is the case that ss->thread == MACH_PORT_NULL, that
is, a global signal.  In the main thread, between __proc_dostop and
__task_create is the __thread_abort call on the signal thread which would
abort any current kernel operation (but leave ss locked).  Later in fork,
in the parent, when _hurd_siglock is unlocked in fork, the parent's
signal thread can proceed and will unlock eventually the global sigstate.
In the client, _hurd_siglock will likewise be unlocked, but the global
sigstate never will be, as the client's signal thread has been configured
to restart execution from _hurd_msgport_receive.  Thus, when the child
tries to unlock ss' critical section lock at the end of fork, it will
first lock the global sigstate, will spin trying to lock it, which can
never be successful, and we get our deadlock.

Options seem to be:

  * Move the locking of _hurd_siglock earlier in post_signal -- but that
    may generally impact performance, if this locking isn't generally
    needed anyway?

    On the other hand, would it actually make sense to wait here until we
    are not any longer in a critical section (which is meant to disable
    signal delivery anway (but not for preempted signals?))?

  * Clear the global sigstate in the fork's child with the rationale that
    we're anyway restarting the signal thread from a clean state.  This
    has now been implemented.

Why has this problem not been observed before Jrmie's patches?  (Or has
it?  Perhaps even more rarely?)  In _S_msg_sig_post, the signal is now
posted to a *global receiver thread*, whereas previously it was posted to
the *designated signal-receiving thread*.  The latter one was in a
critical section in fork, so didn't try to handle the signal until after
leaving the critical section?  (Not completely analyzed and verified.)

Another question is what the signal is that is being received
during/around the time __proc_dostop executes.

 [patch] fix f?chflags prototypes, declare them and their flags.

Although they are defined on GNU/Hurd, f?chflags were never declared. It
seems the BSD prototype actually uses an unsigned long, so we can take
the opportunity to fix the prototype, while adding an actual
declaration.

* misc/chflags.c (chflags): Set flags parameter type to unsigned long instead of
int.
* misc/fchflags.c (fchflags): Likewise.
* sysdeps/mach/hurd/chflags.c (chflags): Likewise.
* sysdeps/mach/hurd/fchflags.c (fchflags): Likewise.
* sysdeps/mach/hurd/bits/stat.h (UF_SETTABLE, UF_NODUMP, UF_IMMUTABLE,
UF_APPEND, UF_OPAQUE, UF_NOUNLINK, SF_SETTABLE, SF_ARCHIVED, SF_IMMUTABLE,
