»No more PTYs« message

Hi!

We've been seeing this on darnassus several times: try to allocate a PTY
(log in via SSH, or start screen, etc.), and get a »No more PTYs«
message.  Now the same happend on flubber: I could log in via SSH, but
starting screen failed.  I did a »ls -l /dev/tty* /dev/pty*« (which will
start all translators due to »stat«ing the nodes) -- and then I was able
to start screen.  Strange?

Grüße,
 Thomas

[PATCH,HURD] sendto: do not crash when addr is NULL

Hi,

currently, sendto() crashes when the specified addr is NULL; the 
attached patch fixes it making sendto() with NULL addr behave as it 
would be a plain send().

Thanks,

Hurd: sendto: do not crash when addr is NULL

Work also when the specified addr is NULL; simplify also the usage of err.

restartable netdde

Hello,

One nifty feature of userland drivers is that you can easily restart
them by just making the translator away. However, that makes pfinet
away, as well as all current network connexions and listening servers.

But pfinet doesn't really need to exit: it could just reopen the network
device after e.g. 1s delay, reconfigure it, and continue as if nothing
happened.

Could somebody have a look?

kernel panic on network activity

Hi,

I attach a screenshot on how my kernel panics when I just "ping" 
localhost. I provide a "screenshot" since I had to uninstall any ssh, 
telnet or login daemon to be able to boot.
This happens after the last debian update I was doing.

dpkg -l | grep hurd
reports: 20120408-3

Any hints?

cthreads to pthreads conversion

So, I have gotten this patch back to where Barry had it in 2008:
It needs testing. Specific changes that I have made are to remove the need for
condition_implies from console-client, pfinet, term, and trans. I, mostly,
followed the pattern set by Vicente in libpipe. (Which was in a strange state
in Barry's patch.) I also audited uses of trylock due to the return values
changing from cthreads to pthreads. The only questionable piece of code is
marked "BDD - Is this sane?" in ufs/sizes.c. I think Barry's replacement is
correct.

Compiling notes:
The patch should apply cleanly to HEAD as of May 14, 2012.

You need an implementation of hurd_condition_wait in libpthread: I will attach
Vicente's, which he put in sysdeps/hurd.

I had to comment out the declaration of hurd_condition_wait in
/usr/include/cthreads.h for the new one to compile.

I had to give the absolute path to libpthread2.a in libpthread.a to get the
linker to link to it. Without doing so, the linker would use the
libpthread2.a somewhere in /lib/, and I would get undefined references to
hurd_condition_wait.

Finally, I had to apply the have_kernel_resources branch to libpthreads. A
broken patch is better than no patch. It is personally frustrating to me to be
changing the source from a working threading library to one which does not
work. At all. Given the code, programs should always fail at the first
pthread_create.

Anyway... this is for testing. Most of the code changes were done by Barry

[PATCH,HURD] Add TLS support

This adds TLS support to GNU/HURD. Using it to replace threadvar will be
part of another patch.  I had to separate the thread state with segments
from the thread state without segments: each thread has its own gs
segment, which needs to be inherited across fork, etc.  I also had to
fix some initialization order.

2009-07-30  Samuel Thibault  <samuel.thibault <at> gnu.org>

	* sysdeps/mach/hurd/bits/libc-lock.h [_LIBC - 0]: Include <tls.h>
	* sysdeps/mach/hurd/tls.h: Include <stdint.h> and <sysdep.h>
	* include/errno.h (__GNU__): Do not define TLS errno for now.

	* sysdeps/generic/thread_state.h (MACHINE_NEW_THREAD_STATE_FLAVOR): New
	macro.
	* sysdeps/mach/thread_state.h (MACHINE_THREAD_STATE_FIX_NEW): New macro.
	* sysdeps/mach/i386/thread_state.h (MACHINE_NEW_THREAD_STATE_FLAVOR):

	New macro, defined to PPC_THREAD_STATE.

	* sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler): Use

	* sysdeps/mach/hurd/i386/tls.h (_hurd_tls_init): Use kern_return_t
	error type. Use first GDT slot, 0x48.
	(_hurd_tls_fork): Use kern_return_t error type.  Duplicate existing LDT
	descriptor instead of creating a new one.

Having regression cases in the libc test suite is always a good idea.
