12 years ago[PATCH] audit: watching subtrees
Al Viro [Sun, 22 Jul 2007 12:04:18 +0000]
[PATCH] audit: watching subtrees

New kind of audit rule predicates: "object is visible in given subtree".
The part that can be sanely implemented, that is.  Limitations:
* if you have hardlink from outside of tree, you'd better watch
it too (or just watch the object itself, obviously)
* if you mount something under a watched tree, tell audit
that new chunk should be added to watched subtrees
* if you umount something in a watched tree and it's still mounted
elsewhere, you will get matches on events happening there.  New command
tells audit to recalculate the trees, trimming such sources of false
positives.

Note that it's _not_ about path - if something mounted in several places
(multiple mount, bindings, different namespaces, etc.), the match does
_not_ depend on which one we are using for access.

Linus Torvalds [Sat, 20 Oct 2007 04:25:45 +0000]
Revert "kconfig: tristate choices with mixed tristate and boolean values"

This reverts commit a5bf3d891a6a0fb5aa122792d965e3774108b923.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:

  "That Kconfig hasn't changed (other than adding new drivers), and it's
   worked that way for several years now ...  so the issue seems to be
   changes in menuconfig/kconfig/etc semantics.

   The issue is that when USB_GADGET=m, it's no longer possible to
   configure peripheral controller drivers as modules ...  the
   controller drivers can now only be configured for static linkage.

   It should be making a choice of one of the controller drivers which
   could work on the target system, and allow that driver to be linked
   either as a module (ok iff USB_GADGET=m) or statically."

Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

pg_init completed with a check condition we just assume we can retry the
pg_init command.  We make this assumption because of incomplete data on
specific check condition code of the HP hardware, and because testing
has shown the HP path initialization command to be idempotent.

Dave Wysochanski [Fri, 19 Oct 2007 21:47:53 +0000]
dm mpath: add retry pg init

This patch allows a failed path group initialisation command to be retried.

It adds a generic MP_RETRY flag and a "pg_init_retries" feature to
device-mapper multipath which limits the number of retries.

1. A hw handler sends a path initialization command to the storage and
the command completes with an error code indicating the command
should be retried.

2. The hardware handler calls dm_pg_init_complete() with MP_RETRY
set in err_flags to ask the dm multipath core to retry.

3. If the retry limit has not been exceeded, pg_init() is retried.
Otherwise fail_path() is called.

If you are using the userspace multipath-tools or device-mapper-multipath
package, you can set pg_init_retries in the 'device' section of your
/etc/multipath.conf file. For example:

features                "2 pg_init_retries 7"

The number of PG retries attempted is reported in the 'dmsetup status' output.

12 years agodm: fix thaw_bdev
Jun'ichi Nomura [Fri, 19 Oct 2007 21:38:43 +0000]
dm: fix thaw_bdev

This patch fixes a bd_mount_sem counter corruption bug in device-mapper.

thaw_bdev() should be called only when freeze_bdev() was called for the
device.
Otherwise, thaw_bdev() will up bd_mount_sem and corrupt the semaphore counter.
struct block_device with the corrupted semaphore may remain in slab cache
and be reused later.

Attached patch will fix it by calling unlock_fs() instead.
unlock_fs() will determine whether it should call thaw_bdev()
by checking the device is frozen or not.

Easy reproducer is:
  #!/bin/sh
  while [ 1 ]; do
     dmsetup --notable create a
     dmsetup --nolockfs suspend a
     dmsetup remove a
  done

It's not easy to see the effect of corrupted semaphore.
So I have tested with putting printk below in bdev_alloc_inode():
        if (atomic_read(&ei->bdev.bd_mount_sem.count) != 1)
                printk(KERN_DEBUG "Incorrect semaphore count = %d (%p)\n",
                        atomic_read(&ei->bdev.bd_mount_sem.count),
                        &ei->bdev);

Without the patch, I saw something like:
 Incorrect semaphore count = 17 (f2ab91c0)

With the patch, the message didn't appear.

The bug was introduced in 2.6.16 with this bug fix:

commit d9dde59ba03095e526640988c0fedd75e93bc8b7
Date:   Fri Feb 24 13:04:24 2006 -0800

    [PATCH] dm: missing bdput/thaw_bdev at removal

    Need to unfreeze and release bdev otherwise the bdev inode with
    inconsistent state is reused later and cause problem.

and backported to 2.6.15.5.

It occurs only in free_dev(), which is called only when the dm device is
removed.  The buggy code is executed only if md->suspended_bdev is
non-NULL and that can happen only when the device was suspended without
noflush.

12 years agodm io:ctl use constant struct size
Milan Broz [Fri, 19 Oct 2007 21:38:36 +0000]
dm io:ctl use constant struct size

Make size of dm_ioctl struct always 312 bytes on all supported
architectures.

This change retains compatibility with already-compiled code because
it uses an embedded offset to locate the payload that follows the
structure.

On 64-bit architectures there is no change at all; on 32-bit
we are increasing the size of dm-ioctl from 308 to 312 bytes.

Currently with 32-bit userspace / 64-bit kernel on x86_64
some ioctls (including rename, message) are incorrectly rejected
by the comparison against 'param + 1'.  This breaks userspace
lvrename and multipath 'fail_if_no_path' changes, for example.

(BTW Device-mapper uses its own versioning and ignores the ioctl
size bits.  Only the generic ioctl compat code on mixed arches
checks them, and that will continue to accept both sizes for now,
but we intend to list 308 as deprecated and eventually remove it.)
