git-NO_HIDDEN

commit 3d1870fa3301c5cd00d5fdab0014c4e22b71fef2
Author: Samuel Thibault <samuel.thibault@ens-lyon.org>
Date:   Tue Oct 3 01:26:58 2017 +0200

    Introduce NO_RTLD_HIDDEN, make hurd use it instead of NO_HIDDEN

    On the Hurd, the rtld needs to see its own dumb versions of a few functions
    (defined in sysdeps/mach/hurd/dl-sysdep.c) overridden by libc's versions once
    loaded. rtld should thus not have hidden attribute for these.  To achieve this,
    the Hurd port used to just define NO_HIDDEN, which disables it completely. For
    now, this changes that to disabling it for all rtld functions, for simplicity.

    See Roland's comment on https://sourceware.org/bugzilla/show_bug.cgi?id=15605#c5

    The ld.so numbers remain at

      8 .rel.plt      000000c8  00000c24  00000c24  00000c24  2**2
                      CONTENTS, ALLOC, LOAD, READONLY, DATA
      9 .plt          000001a0  00000cf0  00000cf0  00000cf0  2**4
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
     10 .plt.got      00000010  00000e90  00000e90  00000e90  2**3
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
     18 .got.plt      00000070  0002d000  0002d000  0002c000  2**2
                      CONTENTS, ALLOC, LOAD, DATA

    which is about 3 times as much as on Linux.

    When linked statically, TLS initialization is not achieved before
    mach_init and alike, so ssp accesses to tcbhead's stack_guard would

    TLS is set up.

XXX: make libc_rwlock recursive

That's very unfortunate: libfakeroot gets initialized from a section
where __libc_setlocale_lock is already locked, and thus the dlerror()
call hangs inside __dcigettext. It happens that Linux doesn't have
the problem probably because pthread_rwlock_wrlock returns a EDEADLK
error instead of hanging, and then the first unlock unlocks, and the
second unlock probably returns an EINVAL. This is all very unsafe, but
that's fakeroot-tcp's matter (see http://bugs.debian.org/845930 for the
follow-up)...

We only use it when constructing the debian installer for -s -r options
anyway.

hurd: Fix O_DIRECTORY | O_NOFOLLOW

Appending / to the path to be looked up makes us always follow a final
symlink, even with O_NOTRANS (since the final resolution is after the
'/'). In the O_DIRECTORY | O_NOFOLLOW case, we thus have to really open
the node and stat it, which we already do anyway, and check for
directory type.

Hurd: fix port leak in TLS

Depending on whether the thread is the main thread or not, the threading
library can have trouble determining whether the thread reference in the
TCB is valid. The simple solution is to let the threading library
initialize the TCB, and use a temporary reference when initializing TLS.

* sysdeps/mach/hurd/i386/tls.h (_hurd_tls_init): Use a temporary thread
reference.

Hurd: make sigstates hold a reference on thread ports

This change is required in order to correctly release per-thread
resources. Directly reusing the threading library reference isn't
possible since the sigstate is also used early in the main thread,
before threading is initialized.

* hurd/hurd/signal.h (_hurd_self_sigstate): Drop thread reference after
calling _hurd_thread_sigstate.
(_hurd_critical_section_lock): Likewise.
* hurd/hurdsig.c (_hurd_thread_sigstate): Add a reference on the thread.

Subject: [PATCH 2/2] Define _PATH_MOUNTED as "/etc/mtab"
Date: Thu, 15 Aug 2013 10:43:35 +0200

Change the definition of _PATH_MOUNTED to "/etc/mtab". This is the
value used on Linux.

The change is motivated by the fact that on Debian /etc/mtab is a
symbolic link to /proc/mounts. This patch adjusts the macro for
non-linux systems such as Hurd. Changing this using
sysdeps/mach/hurd/paths.h causes build problems because
/usr/include/hurd/paths.h is shadowed by this file. This change is
proposed in the hope that aligning the non-linux targets with the
glibc for Linux is perceived as a good thing while fixing this problem
on Debian/Hurd along the way.

* sysdeps/generic/paths.h (_PATH_MOUNTED): Change value to "/etc/mtab".

Fix poll and select POSIX compliancy details about errors

This fixes the following:

- On error, poll must not return without polling, including EBADF, and instead
report POLLHUP/POLLERR/POLLNVAL
- Select must report EBADF if some set contains an invalid FD.

The idea is to move error management to after all select calls, in the
poll/select final treatment. The error is instead recorded in a new `error'
field, and a new SELECT_ERROR bit set.

Thanks Svante Signell for the initial version of the patch.

* hurd/hurdselect.c (SELECT_ERROR): New macro.
(_hurd_select):
- Add `error' field to `d' structures array.
- If a poll descriptor is bogus, set EBADF, but continue with a zero timeout.
- Go through the whole fd_set, not only until _hurd_dtablesize. Return EBADF
there is any bit set above _hurd_dtablesize.
- Do not request io_select on bogus descriptors (SELECT_ERROR).
- On io_select request error, record the error.
- On io_select bogus reply, use EIO error code.
- On io_select bogus or error reply, record the error.
- Do not destroy reply port for bogus FDs.
- On error, make poll set POLLHUP in the EPIPE case, POLLNVAL in the EBADF
case, or else POLLERR.
- On error, make select simulated readiness.

Fix timeout handling in _hurd_select

Rely on servers to implement timeouts, so that very short values (including
0) don't make mach_msg return before valid replies can be received. The
purpose of this scheme is to guarantee a full client-server round-trip,
whatever the timeout value.

This change depends on the new io_select_timeout RPC being implemented by
servers.

* hurd/Makefile (user-interfaces): Add io_reply and io_request.
* hurd/hurdselect.c: Include <sys/time.h>, <hurd/io_request.h> and <limits.h>.
(_hurd_select): Replace the call to __io_select with either __io_select_request
or __io_select_timeout_request, depending on the timeout. Count the number of
ready descriptors (replies for which at least one type bit is set). Implement
the timeout locally when there is no file descriptor.

* 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 Jérémie'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.
