Summary: lots of kernel oopses caused by using inotify syscalls
Product: Ubuntu
Version: unspecified
Platform: i386
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: linux
AssignedTo: fabbione at ubuntu.com
ReportedBy: desrt at desrt.ca
QAContact: kernel-bugs at lists.ubuntu.com
I was just playing around with inotify on my breezy system. I wrote a little
program:
#include <sys/syscall.h>
# define __NR_inotify_init 291
# define __NR_inotify_add_watch 292
# define __NR_inotify_rm_watch 293
static inline int inotify_init (void)
{
return syscall (__NR_inotify_init);
}
static inline int inotify_add_watch (int fd, const char *name, int mask)
{
return syscall (__NR_inotify_add_watch, fd, name, mask);
}
static inline int inotify_rm_watch (int fd, int wd)
{
return syscall (__NR_inotify_rm_watch, fd, wd);
}
int main( void )
{
int fd = inotify_init();
inotify_add_watch( fd, "/home/desrt/Desktop", -1 );
}
Pretty simple stuff... not even vaguely complete. Anyway, it compiled so I
figured "eh.. why not run it", so I did.
At this point, gnome-terminal locked solid. So I hit the close button and
clicked on "force quit" when it came up (thus closing all of my terms). All
attempts to restart gnome-terminal are met with failure. All attempts to start
an xterm result in an xterm-sized window popping up for a split-second then
disappearing. SSHing to the box fails. Basically, anything that attempts to
open a pseudoterminal is screwed at this point.
I am, however, able to SSH to the machine and issue commands (since this just
redirects the output of the command via pipes.. not pseudoterminals.)
I was able to discover that the inotify test program I wrote is locked in
uninteruptable sleep.

I was also able to get a kernel log of lots of oopses. None of them seem
related to inotify, though. Very strange. 'eventd' is a program that I run
from inside a screen session (ie: outputs to a pty). It appears that anything
running at the time connected to a pty and anything I try to start that wants to
use a pty dies.
