14 years agogenirq: temporary fix for level-triggered IRQ resend
Thomas Gleixner [Wed, 1 Aug 2007 15:13:19 +0000 (17:13 +0200)]
genirq: temporary fix for level-triggered IRQ resend

Marcin Slusarz reported a ne2k-pci "hung network interface" regression.

delayed disable relies on the ability to re-trigger the interrupt in the
case that a real interrupt happens after the software disable was set.
In this case we actually disable the interrupt on the hardware level
_after_ it occurred.

On enable_irq, we need to re-trigger the interrupt. On i386 this relies
on a hardware resend mechanism (send_IPI_self()).

Actually we only need the resend for edge type interrupts. Level type
interrupts come back once enable_irq() re-enables the interrupt line.

I assume that the interrupt in question is level triggered because it is
shared and above the legacy irqs 0-15:

17:         12   IO-APIC-fasteoi   eth1, eth0

Looking into the IO_APIC code, the resend via send_IPI_self() happens
unconditionally. So the resend is done for level and edge interrupts.
This makes the problem more mysterious.

The code in question lib8390.c does

disable_irq();
fiddle_with_the_network_card_hardware()
enable_irq();

The fiddle_with_the_network_card_hardware() might cause interrupts,
which are cleared in the same code path again,

Marcin found that when he disables the irq line on the hardware level
(removing the delayed disable) the card is kept alive.

So the difference is that we can get a resend on enable_irq, when an
interrupt happens during the time, where we are in the disabled region.

14 years agoFix WARN_ON() on bitfield ops
Linus Torvalds [Wed, 1 Aug 2007 04:12:07 +0000 (21:12 -0700)]
Fix WARN_ON() on bitfield ops

Alexey Dobriyan noticed that the new WARN_ON() semantics that were
introduced by commit 684f978347deb42d180373ac4c427f82ef963171 (to also
return the value to be warned on) didn't compile when given a bitfield,
because the typeof doesn't work for bitfields.

So instead of the typeof trick, use an "int" variable together with a
"!!(x)" expression, as suggested by Al Viro.

To make matters more interesting, Paul Mackerras points out that that is
sub-optimal on Power, but the old asm-coded comparison seems to be buggy
anyway on 32-bit Power if the conditional was 64-bit, so I think there
are more problems there.

Regardless, the new WARN_ON() semantics may have been a bad idea.  But
this at least avoids the more serious complications.

Jesper Juhl [Tue, 31 Jul 2007 07:39:18 +0000 (00:39 -0700)]
Fix a use after free bug in kernel->userspace relay file support

Coverity spotted what looks like a real possible case of using a variable
after it has been freed.  The problem is in
kernel/relay.c::relay_open_buf()

If the code hits "goto free_buf;" it ends up in this code :

  free_buf:
     relay_destroy_buf(buf); <--- calls kfree() on 'buf'.
  free_name:
    kfree(tmpname);
  end:
   return buf; <-- use after free of 'buf'.

I read through the callers and they all handle a NULL return from this
function as an error (and hitting the 'free_buf' label only happens on
failure to chan->cb->create_buf_file(), so that looks like a clear error to
me).

The patch simply sets 'buf' to NULL after the call to
relay_destroy_buf(buf); - as far as I can see that should take care of the
problem.

The patch also corrects a reference to a documentation file while
I was at it.

Note from Mathieu: the documentation reference change should have been
done in a separate patch, but I guess no one will really care.

isofs: mounting to regular file may succeed

It turned out that mounting a corrupted ISO image to a regular file may
succeed, e.g.  if an image was prepared as follows:

$ dd if=correct.iso of=bad.iso bs=4k count=8

We then can mount it to a regular file:

# mount -o loop -t iso9660 bad.iso /tmp/file

But mounting it to a directory fails with -ENOTDIR, simply because
the root directory inode doesn't have S_IFDIR set and the condition
in graft_tree() is met:

if (S_ISDIR(nd->dentry->d_inode->i_mode) !=
      S_ISDIR(mnt->mnt_root->d_inode->i_mode))
return -ENOTDIR

This is because the root directory inode was read from an incorrect
block. It's supposed to be read from sbi->s_firstdatazone, which is
an absolute value and gets messed up in the case of an incorrect image.

In order to somehow circumvent this we have to check that the root
directory inode is actually a directory after all.

The fourth argument of sys_futex is ignored when op == FUTEX_WAKE_OP,
but futex_wake_op expects it as its nr_wake2 parameter.

The only user of this operation in glibc is always passing 1, so this
bug had no consequences so far.

 (*) Start the lock manager thread under a mutex to avoid a race.

 (*) Made the locking non-fair: New readlocks will jump pending writelocks if

14 years agoFix user struct leakage with locked IPC shem segment
Pavel Emelianov [Tue, 31 Jul 2007 07:38:48 +0000 (00:38 -0700)]
Fix user struct leakage with locked IPC shem segment

When user locks an ipc shmem segmant with SHM_LOCK ctl and the segment is
already locked the shmem_lock() function returns 0.  After this the
subsequent code leaks the existing user struct:

== ipc/shm.c: sys_shmctl() ==
     ...
     err = shmem_lock(shp->shm_file, 1, user);
     if (!err) {
          shp->shm_perm.mode |= SHM_LOCKED;
          shp->mlock_user = user;
     }
     ...
==

Other results of this are:
1. the new shp->mlock_user is not get-ed and will point to freed
   memory when the task dies.
2. the RLIMIT_MEMLOCK is screwed on both user structs.

The exploit looks like this:

==
    id = shmget(...);
    setresuid(uid, 0, 0);
    shmctl(id, SHM_LOCK, NULL);
    setresuid(uid + 1, 0, 0);
    shmctl(id, SHM_LOCK, NULL);
==

My solution is to return 0 to the userspace and do not change the
segment's user.
