Just another kernel memory DoS, whoopeee. Its also prehistoric. Chris Woods
reported it in 1995 and there are older BSD reports/bugs.
Its a subset of the far funkier problem
fd = nil
for(;;) {
open AF_UNIX fd3
if(fd != nil)
stuff AF_UNIX fd down fd3
fd = fd3
while(!full(fd))
{
open AF_UNIX fd2
stuff AF_UNIX fd2 down fd
close fd2
}
}
Queue data as well for better party trick.
Please don't pass on the improved version to the reporter. I'm having fun
seeing if they are bright enough to work it out themselves

Not sure what to do about this one. I suppose Greg knows :) It's not an issue at all, so I'm closing it. |
