Hello,
I hope you guys can help, I cannot use any kernel 2.4 >23 without
the here described problem.
[1.] One line summary of the problem:
strange error messages concerning memory allocation
searching teh web for solutions to my problem I have already found
a thread in a mailing list but no solution was mentioned, also the
guys who talked about the error didn't answer to my direct mail.
[2.] Full description of the problem/report:
The machine is a database server without any other service except sshd
running. I do some tests on the ICP-Vortex GDT controller every 2 minutes.
by using
# cat /proc/scsi/gdt/2
but the output of cat stops without beeing completed.
This is what I see in the syslog file every time when I use the cat
command (the messages beginn after 3 days uptime):
--> /var/log/messages
kernel: __alloc_pages: 0-order allocation failed (gfp=0x21/0)
What do you propose to do for I can get the information I need for
longer than three days without reboot? This is a highly used database
server in production environment.
[3.] Keywords (i.e., modules, networking, kernel):
kernel, memory
[4.] Kernel version (from /proc/version):
Linux version 2.4.27 (root@widbrz01) (gcc version 3.3.1
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
none
[6.] A small shell script or example program which triggers the
problem (if possible)
see 2.
[7.] Environment

Ingo,
I've seen another report like this one - I'm convinced there
is something odd with the gdth proc handling code.
Can you "echo 1 > /proc/sys/vm/vm_gfp_debug" and
rerun the "cat /proc/scsi/gdt/2" please?
Achim,
This is not the first person I see complaining about
exact same bug (memory allocation failure while reading
/proc/scsi/gdt/xxx
Do you have a card around so we can test?
Thanks

Hi Marcelo,
there are a lot of sprintf() in gdth_get_info(). There are a few overflow
checks, but they're being done *after* the problem happens, so it may
be possible that people experiencing problems get some data overwritten
which prevents something else from been released later.
Moreover, when some of those checks decide that the buffer is full, they
jump to stop_output without calling gdth_ioctl_free(). So it may also be
possible that this user who regularly reads /proc has his output truncated
and some memory never freed.
Regards,
Willy
