Ack...

First, I'm glad I wasn't hallucinating, and that the mail did indeed get
seen by someone.

Second, instead of reverting, can't we simply move those two lines up a
bit:
case IPC_RMID:
if (current->euid == shp->u.shm_perm.uid ||
current->euid == shp->u.shm_perm.cuid ||
capable(CAP_SYS_ADMIN)) {
shp->u.shm_perm.mode |= SHM_DEST;
+ /* Do not find it any more */
+ shp->shm_perm.key = IPC_PRIVATE;
if (shp->u.shm_nattch <= 0)
killseg (id);
break;

This way, we're not violating specs, programs work, *and* we're not
touching freshly kfree()d storage?

Ah, but it does matter ! We break compatibility with other systems (and
our manpages, and possibly standards) if we don't mark the segment
IPC_PRIVATE upon removal -

Marking the segment IPC_PRIVATE allows its continued use by those alread
connected to the segment (until the count drops to zero, and its
deleted), but *prevents* new users from attaching to the segment.

I started down this road because we weren't marking the segment, was
delighted to see it done in pre3 - but it seemed like the setting
wasn't always done ;-{

This being so midbogglingly critical a bug that nobody noticed until 2.2.18
and the bug existed since 1.2 or earlier. I think I can wait for 2.2.20

No, I do not think that it's minor. We had to bring down running
application servers to be able to start another one, because the new
one couldn't create or attach the systemwide os-monitoring
segment and thus refused to start. That's very bad behaviour.

Yes, I understand that. But I never got any note that my fix is broken
and I still do not understand what's the concern.

We are holding the BKL while doing this. And if shm_close does not get
called with it we should probably acquire it.

Unless Im misreading the code the segment you poke at has potentially been
freed before it is written too.

Oh yes I was blind, shame on me. Here comes a fixed version.
