Re: kqueue(2) problems - CUPS does not work

[Frank Kardel <kardel%netbsd.org@localhost>]

Hello Matthias !

See kern/41593: descriptor handling broken.

Symptoms
   close(0)-> -1, EBADF
   dup(16) -> 23 (why? - 0 should be available)

In the cupy case fd 0 reacts with EBADF on the read from perl when 
reading the file to be printed from stdin.

The problem start to appear with the fd optimization around 2006-05-24.

Additional information the fd_getfile() in sys_close() and sys_read() 
return NULL (via breakpoints in kernel debugger).

So far I had now responses to my emails about this to source-changes-d@.

Best regards,
 Frank
