[PATCH] root mount failure: emit filesystems attempted

When we fail to mount from a valid root device list out the filesystems we
have tried to mount it with.  This gives the user vital diagnostics as to
what is missing from their kernel.

For example in the fragment below the kernel does not have CRAMFS compiled
into the kernel and yet appears to recognise it at the RAMDISK detect
stage.  Later the mount fails as we don't have the filesystem.

  RAMDISK: cramfs filesystem found at block 0
  RAMDISK: Loading 1604KiB [1 disk] into ram disk... done.
  XFS: bad magic number
  XFS: SB validate failed
  No filesystem could mount root, tried: reiserfs ext3 ext2 msdos vfat
    iso9660 jfs xfs
  Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)

Hua Zhong [Mon, 15 May 2006 16:44:22 +0000]
[PATCH] fix can_share_swap_page() when !CONFIG_SWAP

can_share_swap_page() is used to check if the page has the last reference.
This avoids allocating a new page for COW if it's the last page.

However, if CONFIG_SWAP is not set, can_share_swap_page() is defined as 0,
thus always causes a copy for the last COW page.  The below simple patch
fixes it.

[PATCH] v9fs: signal handling fixes

Multiple races can happen when v9fs is interrupted by a signal and Tflush
message is sent to the server.  After v9fs sends Tflush it doesn't wait
until it receives Rflush, and possibly the response of the original

13 years ago[PATCH] smbfs: Fix slab corruption in samba error path
Jan Niehusmann [Mon, 15 May 2006 16:44:12 +0000]
[PATCH] smbfs: Fix slab corruption in samba error path

Yesterday, I got the following error with 2.6.16.13 during a file copy from
a smb filesystem over a wireless link.  I guess there was some error on the
wireless link, which in turn caused an error condition for the smb
filesystem.

In the log, smb_file_read reports error=4294966784 (0xfffffe00), which also
shows up in the slab dumps, and also is -ERESTARTSYS.  Error code 27499
corresponds to 0x6b6b, so the rq_errno field seems to be the only one being
set after freeing the slab.

In smb_add_request (which is the only place in smbfs where I found
ERESTARTSYS), I found the following:

        if (!timeleft || signal_pending(current)) {
                /*
                 * On timeout or on interrupt we want to try and remove the
                 * request from the recvq/xmitq.
                 */
                smb_lock_server(server);
                if (!(req->rq_flags & SMB_REQ_RECEIVED)) {
                        list_del_init(&req->rq_queue);
                        smb_rput(req);
                }
                smb_unlock_server(server);
        }
[...]
        if (signal_pending(current))
                req->rq_errno = -ERESTARTSYS;

I guess that some codepath like smbiod_flush() caused the request to be
removed from the queue, and smb_rput(req) be called, without
SMB_REQ_RECEIVED being set.  This violates an asumption made by the quoted
code.

Then, the above code calls smb_rput(req) again, the req gets freed, and
req->rq_errno = -ERESTARTSYS writes into the already freed slab.  As
list_del_init doesn't cause an error if called multiple times, that does
cause the observed behaviour (freed slab with rq_errno=-ERESTARTSYS).

If this observation is correct, the following patch should fix it.

I wonder why the smb code uses list_del_init everywhere - using list_del
instead would catch such situations by poisoning the next and prev
pointers.

Sun, 27 Jun 2004 17:55:19 +0000 (17:55 +0000)
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=92b3db26d31cf21b70e3c1eadc56c179506d8fbe

The function symbol_put_addr() will deadlock the kernel.

symbol_put_addr() would acquire modlist_lock, then while holding the lock call
two functions kernel_text_address() and module_text_address() which also try
to acquire the same lock.  This deadlocks the kernel of course.

This patch changes symbol_put_addr() to not acquire the modlist_lock, it
doesn't need it since it never looks at the module list directly.  Also, it
now uses core_kernel_text() instead of kernel_text_address().  The latter has
an additional check for addr inside a module, but we don't need to do that
since we call module_text_address() (the same function kernel_text_address
uses) ourselves.

[PATCH] VIA quirk fixup, additional PCI IDs

An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an
overly-zealous PCI quirk to only poke those VIA devices that need it.
However, some PCI devices were not included in what I hope is now the full
list.  Consequently we're failing to run the quirk on all machines which need
it, causing IRQ routing failures.

This should I hope correct this.

[PATCH] autofs4: NFY_NONE wait race fix

This patch fixes two problems.

First, the comparison of entries in the waitq.c was incorrect.

Second, the NFY_NONE check was incorrect. The test of whether the dentry
is mounted if ineffective, for example, if an expire fails then we could
wait forever on a non existant expire. The bug was identified by Jeff
Moyer.

The patch changes autofs4 to wait on expires only as this is all that's
needed.  If there is no existing wait when autofs4_wait is call with a type
of NFY_NONE it delays until either a wait appears or the the expire flag is
cleared.

Alternative fix for MMC oops on unmount after removal

Make sure to clear the driverfs_dev pointer when we do del_gendisk() (on
disk removal), so that other users that may still have a ref to the disk
won't try to use the stale pointer.

Also move the KOBJ_REMOVE uevent handler up, so that the uevent still
has access to the driverfs_dev data.

This all should hopefully fix the problems with MMC umounts after device
removals that caused commit 56cf6504fc1c0c221b82cebc16a444b684140fb7 and

13 years ago[NEIGH]: Fix IP-over-ATM and ARP interaction.
Simon Kelley [Fri, 12 May 2006 21:56:08 +0000]
[NEIGH]: Fix IP-over-ATM and ARP interaction.

The classical IP over ATM code maintains its own IPv4 <-> <ATM stuff>
ARP table, using the standard neighbour-table code. The
neigh_table_init function adds this neighbour table to a linked list
of all neighbor tables which is used by the functions neigh_delete()
neigh_add() and neightbl_set(), all called by the netlink code.

Once the ATM neighbour table is added to the list, there are two
tables with family == AF_INET there, and ARP entries sent via netlink
go into the first table with matching family. This is indeterminate
and often wrong.

To see the bug, on a kernel with CLIP enabled, create a standard IPv4
ARP entry by pinging an unused address on a local subnet. Then attempt
to complete that entry by doing

ip neigh replace <ip address> lladdr <some mac address> nud reachable

Looking at the ARP tables by using

ip neigh show

will reveal two ARP entries for the same address. One of these can be
found in /proc/net/arp, and the other in /proc/net/atm/arp.

This patch adds a new function, neigh_table_init_no_netlink() which
does everything the neigh_table_init() does, except add the table to
the netlink all-arp-tables chain. In addition neigh_table_init() has a
check that all tables on the chain have a distinct address family.
The init call in clip.c is changed to call
neigh_table_init_no_netlink().

Since ATM ARP tables are rather more complicated than can currently be
handled by the available rtattrs in the netlink protocol, no
functionality is lost by this patch, and non-ATM ARP manipulation via
netlink is rescued. A more complete solution would involve a rtattr
for ATM ARP entries and some way for the netlink code to give
neigh_add and friends more information than just address family with
which to find the correct ARP table.

[ I've changed the assertion checking in neigh_table_init() to not
  use BUG_ON() while holding neigh_tbl_lock.  Instead we remember that
  we found an existing tbl with the same family, and after dropping
  the lock we'll give a diagnostic kernel log message and a stack dump.

This reverts commit 56cf6504fc1c0c221b82cebc16a444b684140fb7.

Both Erik Mouw and Andrew Vasquez independently pinpointed this commit
as causing problems, where the slab cache for a driver is never released
(most obviously causing problems when immediately re-loading that
driver, resulting in a "kmem_cache_create: duplicate cache <xyz>"
message, but it can also cause other trouble).

James Bottomley dug into it, and reports:

  "OK, here's the scoop.  The problem patch adds a get of driverfs_dev in
   add_disk(), but doesn't put it again until disk_release() (which occurs
   on final put_disk() of the gendisk).

   However, in SCSI, the driverfs_dev is the sdev_gendev.  That means
   there's a reference held on sdev_gendev  until final disk put.
   Unfortunately, we use the driver model driver_remove to trigger
   del_gendisk (which removes the gendisk from visibility and decrements
   the refcount), so we've introduced an unbreakable deadlock in the
   reference counting with this.

   I suggest simply reversing this patch at the moment.  If Russell and
   Jens can tell me what they're trying to do I'll see if there's another
   way to do it."

so hereby the patch gets reverted, waiting for a better fix.

[PATCH] USB: fix omninet driver bug

I introduced this way back in 2.6.13 when adding the port lock logic.
This device talks out through different "ports" all at the same time, so
the lock logic was wrong, preventing any data from ever being sent
properly.

It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race.  a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the

error = -110

The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued.  This affects only device startup.

[BLOCK] limit request_fn recursion

Don't recurse back into the driver even if the unplug threshold is met,
when the driver asks for a requeue. This is both silly from a logical
point of view (requeues typically happen due to driver/hardware
shortage), and also dangerous since we could hit an endless request_fn
-> requeue -> unplug -> request_fn loop and crash on stack overrun.

Also limit blk_run_queue() to one level of recursion, similar to how
blk_start_queue() works.

This patch fixed a real problem with SLES10 and lpfc, and it could hit
any SCSI lld that returns non-zero from it's ->queuecommand() handler.

ptrace_attach: fix possible deadlock schenario with irqs

Eric Biederman points out that we can't take the task_lock while holding
tasklist_lock for writing, because another CPU that holds the task lock
might take an interrupt that then tries to take tasklist_lock for writing.

Which would be a nasty deadlock, with one CPU spinning forever in an
interrupt handler (although admittedly you need to really work at
triggering it ;)

Since the ptrace_attach() code is special and very unusual, just make it
be extra careful, and use trylock+repeat to avoid the possible deadlock.

661FX7MI-S motherboard which uses the SiS 661FX chipset.  The patch adds
an entry to mii_chip_info for the transceiver.

The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.

Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits.  There were fifth second pauses in refresh of large xterms,
and it made Netrek suck.  I can provide further test data.

Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.

I wasn't able to identify the actual transceiver, so the description
field is a guess.

This patch is similar to Artur Skawina's patch:
http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2

I'm not sure, but I wonder if it means the default behaviour should be
changed, so as to better handle future transceivers.

Diff is against 2.6.16.13.

[SCSI] mptfc: race between mptfc_register_dev and mptfc_target_alloc

A race condition exists in mptfc between the thread registering a device
with the fc transport and the scan work generated by the transport.
This race existed prior to the application of the mptfc bug fix patch.

mptfc_register_dev() calls fc_remote_port_add() with the FC_RPORT_ROLE_TARGET
bit set in the rport ids passed to the function.  Having this bit set causes
fc_remote_port_add() to schedule a scan of the device.

This scan can execute before mptfc_register_dev() can fill in the dd_data
in the rport structure.  When this happens, mptfc_target_alloc() will fail
because dd_data is null.

Attached is a patch which fixes the problem.  The patch changes the rport ids
passed to fc_remote_port_add() to not have the TARGET bit set.  This prevents
the scan from being scheduled.  After mptfc_register_dev() fills in the rport
dd_data field, fc_remote_port_rolechg() is called, changing the role of the
rport to TARGET.  Thus, the scan is scheduled after dd_data is filled
in which prevents the failure in mptfc_target_alloc().

[NET] linkwatch: Handle jiffies wrap-around

The test used in the linkwatch does not handle wrap-arounds correctly.
Since the intention of the code is to eliminate bursts of messages we
can afford to delay things up to a second.  Using that fact we can
easily handle wrap-arounds by making sure that we don't delay things
by more than one second.

This is based on diagnosis and a patch by Stefan Rompf.

[PATCH] scx200_acb: Fix for the CS5535 errata

This is a fix for the CS5535 errata 111:

When the SMBus controller tries to access a non-existing device, it sets
the NEGACK bit, SMBus I/O offset 01h[4], to 1 after it detects no
acknowledge at the ninth clock.  The specification states that the bit
can be cleared by writing a 1 to it, but under certain circumstances it
is possible for this bit to not clear.

Writing a 0 to the bit resets the internal state machine and clears the
issue.

Since all writable bits in ACBST are W1C bits (write-one-to-clear) the
second write doesn't affect any other logic except the buggy NEGACK
state machine. The second write clears an internal register which is
responsible for "overwriting" the NEGACK bit in ACBST.

Roland Dreier [Tue, 9 May 2006 17:50:29 +0000]
IB/mthca: Fix race in reference counting

Fix races in in destroying various objects.  If a destroy routine
waits for an object to become free by doing

wait_event(&obj->wait, !atomic_read(&obj->refcount));
/* now clean up and destroy the object */

and another place drops a reference to the object by doing

if (atomic_dec_and_test(&obj->refcount))
wake_up(&obj->wait);

then this is susceptible to a race where the wait_event() and final
freeing of the object occur between the atomic_dec_and_test() and the
wake_up().  And this is a use-after-free, since wake_up() will be
called on part of the already-freed object.

Fix this in mthca by replacing the atomic_t refcounts with plain old
integers protected by a spinlock.  This makes it possible to do the
decrement of the reference count and the wake_up() so that it appears
as a single atomic operation to the code waiting on the wait queue.

While touching this code, also simplify mthca_cq_clean(): the CQ being
cleaned cannot go away, because it still has a QP attached to it.  So
there's no reason to be paranoid and look up the CQ by number; it's
perfectly safe to use the pointer that the callers already have.

[PATCH] USB: ub oops in block_uevent

In kernel 2.6.16, if a mounted storage device is removed, an oops happens
because ub supplies an interface device (and kobject) to the block layer,

to pin device structures.

The code in ub was broken this way for years. But the bug was exposed only
by 2.6.16 when it started to call block_uevent on close, which traverses
device structures (kobjects actually).
