Subject: gpm: oops() invoked from gpn.c(293).

Date: Mon, 16 Aug 1999 11:56:27 +1000 (EST)

Package: gpm
Version: 1.17.8-6

Hi.

I did :
#tail -f /var/logs/syslog > /dev/tty8&

then took a big swipe of the output on tty8 with the mouse
and dumped it on that console.

gpm suddenly died. When I tried to restart gpm I got this
message in syslog:

Aug 10 21:37:41 sparky /usr/sbin/gpm[29894]: oops() invoked from gpn.c(293)
Aug 10 21:37:41 sparky /usr/sbin/gpm[29894]: gpm already running as pid 175: File exists

Deleting /var/run/gpm.pid then allowed gpm to be restarted successfully.

I'm unable to reproduce this, can you readily reproduce this?

Hi,

At Joey's request I reproduced this tonight with rather horrifying results..

open a vc that does not read input:
eg.
tail -f /var/log/syslog > /dev/tty8&
(where tty8 was previously unused and does not have a getty running on it)

select a large block of text with the mouse and paste it repeatedly to
tty8 until it no longer will accept further input.


gpm then hangs doing paste_selection (according to ps) and the nightmare
begins...

I first attempted to kill gpm with init.d/gpm stop -- that fails leaving
gpm running in a tight loop eating all the cpu cycles it can get.

from there gpm became almost totally unkillable..  even kill -9 would not
make it stop!  It stayed that way until the pasted input was read when
I did 'openvc -c8 -s -f ae' after which the selection was pasted and gpm
finally died.


I suspect this is as much caused by overflowing the input buffer as it
is by gpm (or selection) as such, but paste_selection should probably
handle this (rare and self inflicted ;) condition a little more gracefully.

That the process refused to die when sent SIGKILL is certainly inviting a
closer look..

the machine I tried this on is running gpm 1.17.8-3 and kernel 2.2.10-ac2

best,
Ron.

I have tried to replicate the August 1999 testing as described in this
bug and cannot repeat the error.

Either I'm missing something or this bug is no longer present
