[User-mode-linux-user] report on 2.3.99-pre8 problems

[<ua...@al...>]

Hi Jeff!!!

after exec'ng the uml kernel, the only two process that start (and stay in a
busy loop) are:

root       304   298  0 12:53 pts/1    00:00:00 ./linux [(input thread)]
root       305   304 80 12:53 pts/1    00:00:49 ./linux [(tracing thread)]

as I said in the previous mail input thread is on select.

linux tracing thread is in a infinite loop executing:

wait4(-1, 0x50001fe4, WUNTRACED, NULL)  = -1 ECHILD (No child processes)

tha's in trap_user.c:int signals(void *arg)

debugging from the input thread

(gdb) print "%s", log_buf

Program received signal SIGSEGV, Segmentation fault.
<function called from gdb>
The program being debugged stopped while in a function called from GDB.
When the function (malloc) is done executing, GDB will silently
stop (instead of continuing to evaluate the expression containing
the function call).


debugging from the "child":

(gdb) print "%s", log_buf
No memory available to program: call to malloc failed

I have repeated 2 times these tests with the same sympthoms


Of course there is enough mem:

# free
             total       used       free     shared    buffers     cached
Mem:         63688      60560       3128      22720      32400       9712
-/+ buffers/cache:      18448      45240
Swap:        72256       6264      65992


I also executed the kernel with mem=8M

with the same results...


The following precompiled images does work:

Linux version 2.3.36-1um (jd...@cc...)
Linux version 2.3.99-pre6-1um (jd...@cc...)


I'm totally lost... I hope I can investigage on it next days

Thanks for your support && Best wishes
