We did not correctly decode session with preceding extension

headers, skb->nh.raw + 40 + 1 - skb->data was minus, and

Herbert Xu [Tue, 18 Apr 2006 20:24:14 +0000]
[TCP]: Fix truesize underflow

There is a problem with the TSO packet trimming code.  The cause of
this lies in the tcp_fragment() function.

When we allocate a fragment for a completely non-linear packet the
truesize is calculated for a payload length of zero.  This means that
truesize could in fact be less than the real payload length.

When that happens the TSO packet trimming can cause truesize to become
negative.  This in turn can cause sk_forward_alloc to be -n * PAGE_SIZE
which would trigger the warning.

I've copied the code DaveM used in tso_fragment which should work here.

Also, add a comment, so that people who read the code understand why we
do what looks like a no-op.

(Again, this won't actually matter to any sane user, since libc will
save and restore the register gcc stomps on, but it's still wrong to
stomp on it)

x86: don't allow tail-calls in sys_ftruncate[64]()

Gcc thinks it owns the incoming argument stack, but that's not true for
"asmlinkage" functions, and it corrupts the caller-set-up argument stack
when it pushes the third argument onto the stack.  Which can result in
%ebx getting corrupted in user space.

Now, normally nobody sane would ever notice, since libc will save and
restore %ebx anyway over the system call, but it's still wrong.

I'd much rather have "asmlinkage" tell gcc directly that it doesn't own
the stack, but no such attribute exists, so we're stuck with our hacky
manual "prevent_tail_call()" macro once more (we've had the same issue
before with sys_waitpid() and sys_wait4()).

In current code, we are re-reading cic->key after dead cic->key check.
So, in theory, it may really re-read *after* cfq_exit_queue() seted NULL.

To avoid race, we copy it to stack, then use it. With this change, I
guess gcc will assign cic->key to a register or stack, and it wouldn't
be re-readed.

13 years agopowerpc: Use correct sequence for putting CPU into nap mode
Paul Mackerras [Tue, 18 Apr 2006 11:49:11 +0000]
powerpc: Use correct sequence for putting CPU into nap mode

We weren't using the recommended sequence for putting the CPU into
nap mode.  When I changed the idle loop, for some reason 7447A cpus
started hanging when we put them into nap mode.  Changing to the
recommended sequence fixes that.

The complexity here is that the recommended sequence is a loop that
keeps putting the cpu back into nap mode.  Clearly we need some way
to break out of the loop when an interrupt (external interrupt,
decrementer, performance monitor) occurs.  Here we use a bit in
the thread_info struct to indicate that we need this, and the exception
entry code notices this and arranges for the exception to return
to the value in the link register, thus breaking out of the loop.
We use a new `local_flags' field in the thread_info which we can
alter without needing to use an atomic update sequence.

The PPC970 has the same recommended sequence, so we do the same thing
there too.

This also fixes a bug in the kernel stack overflow handling code on
32-bit, since it was causing a value that we needed in a register to
get trashed.

13 years ago[PATCH] shmat: stop mprotect from giving write permission to a readonly attachment...
Hugh Dickins [Wed, 12 Apr 2006 21:34:27 +0000]
[PATCH] shmat: stop mprotect from giving write permission to a readonly attachment (CVE-2006-1524)

I found that all of 2.4 and 2.6 have been letting mprotect give write
permission to a readonly attachment of shared memory, whether or not IPC
would give the caller that permission.

SUS says "The behaviour of this function [mprotect] is unspecified if the
mapping was not established by a call to mmap", but I don't think we can
interpret that as allowing it to subvert IPC permissions.

I haven't tried 2.2, but the 2.2.26 source looks like it gets it right; and
the patch below reproduces that behaviour - mprotect cannot be used to add
write permission to a shared memory segment attached readonly.

This patch is simple, and I'm sure it's what we should have done in 2.4.0:
if you want to go on to switch write permission on and off with mprotect,
just don't attach the segment readonly in the first place.

However, we could have accumulated apps which attach readonly (even though
they would be permitted to attach read/write), and which subsequently use
mprotect to switch write permission on and off: it's not unreasonable.

I was going to add a second ipcperms check in do_shmat, to check for
writable when readonly, and if not writable find_vma and clear VM_MAYWRITE.
 But security_ipc_permission might do auditing, and it seems wrong to
report an attempt for write permission when there has been none.  Or we
could flag the vma as SHM, note the shmid or shp in vm_private_data, and
then get mprotect to check.

But the patch below is a lot simpler: I'd rather stick with it, if we can
convince ourselves somehow that it'll be safe.

      This patch forces the user to specify what type of adapter is present when
      loading i2c-parport or i2c-parport-light.  If none is specified, the driver
      init simply fails - instead of assuming adapter type 0.

      This alleviates the sometimes lengthy boot time delays which can be caused
      by accidentally building one of these into a kernel along with several i2c
      slave drivers that have lengthy probe routines (e.g. hwmon drivers).

David Brownell [Sat, 1 Apr 2006 18:21:52 +0000]
[PATCH] dma doc updates

This updates the DMA API documentation to address a few issues:

 - The dma_map_sg() call results are used like pci_map_sg() results:
   using sg_dma_address() and sg_dma_len().  That's not wholly obvious
   to folk reading _only_ the "new" DMA-API.txt writeup.

 - Buffers allocated by dma_alloc_coherent() may not be completely
   free of coherency concerns ... some CPUs also have write buffers
   that may need to be flushed.

 - Cacheline coherence issues are now mentioned as being among issues
   which affect dma buffers, and complicate/prevent using of static and
   (especially) stack based buffers with the DMA calls.

I don't think many drivers currently need to worry about flushing write
buffers, but I did hit it with one SOC using external SDRAM for DMA
descriptors:  without explicit writebuffer flushing, the on-chip DMA
controller accessed descriptors before the CPU completed the writes.

Grzegorz Janoszka [Tue, 21 Mar 2006 10:57:19 +0000]
[PATCH] arch/i386/pci/irq.c - new VIA chipsets (fwd)

I use 2.6.15.6 Linux kernel and found some problems. I have about 100
Linux boxes (all with the same (binary the same) kernel). Last time I have
upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2,
.4 and .6) and I have found some problems on VIA based PC's. Probably the
reason of this is that some VIA chipsets are unrecognized by IRQ router.

In line 586 there is: /* FIXME: add new ones for 8233/5 */

There were only a few of chipsets ID's there, some of my VIA chipsets were
not present and kernel used default IRQ router.

I have added three entries, so that the code looks like:

        case PCI_DEVICE_ID_VIA_82C596:
        case PCI_DEVICE_ID_VIA_82C686:
        case PCI_DEVICE_ID_VIA_8231:
        case PCI_DEVICE_ID_VIA_8233A:
        case PCI_DEVICE_ID_VIA_8235:
        case PCI_DEVICE_ID_VIA_8237:
        case PCI_DEVICE_ID_VIA_8237_SATA:
                /* FIXME: add new ones for 8233/5 */
                r->name = "VIA";
                r->get = pirq_via_get;
                r->set = pirq_via_set;
                return 1;
        }

The kernel goes fine but I haven't testes it for weeks, I'm just a moment
after reboot :)
One thing is different (better?):
Using previus kernel I had:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0
now I have:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11

Maybe it is good idea to add there some more VIA chipsets?
The ones I have added seem to be OK.

The init function for the RPA PCI Hotplug driver returns -ENODEV in the

bad, since hot-capable slots can be added after boot to a purely virtual

on the rpaphp module.

Ryan Wilson [Wed, 22 Mar 2006 21:26:25 +0000]
[PATCH] driver core: driver_bind attribute returns incorrect value

The manual driver <-> device binding attribute in sysfs doesn't return
the correct value on failure or success of driver_probe_device.
driver_probe_device returns 1 on success (the driver accepted the
device) or 0 on probe failure (when the driver didn't accept the
device but no real error occured). However, the attribute can't just
return 0 or 1, it must return the number of bytes consumed from buf
or an error value. Returning 0 indicates to userspace that nothing
was written (even though the kernel has tried to do the bind/probe and
failed). Returning 1 indicates that only one character was accepted in
which case userspace will re-try the write with a partial string.

A more correct version of driver_bind would return count (to indicate
the entire string was consumed) when driver_probe_device returns 1
and -ENODEV when driver_probe_device returns 0. This patch makes that
change.

[PATCH] BLOCK: delay all uevents until partition table is scanned

[BLOCK] delay all uevents until partition table is scanned

Here we delay the annoucement of all block device events until the
disk's partition table is scanned and all partition devices are already
created and sysfs is populated.

We have a bunch of old bugs for removable storage handling where we
probe successfully for a filesystem on the raw disk, but at the
same time the kernel recognizes a partition table and creates partition
devices.
Currently there is no sane way to tell if partitions will show up or not
at the time the disk device is announced to userspace. With the delayed
events we can simply skip any probe for a filesystem on the raw disk when
we find already present partitions.

NeilBrown [Mon, 20 Mar 2006 06:53:53 +0000]
[PATCH] sysfs: Allow sysfs attribute files to be pollable

It works like this:
  Open the file
  Read all the contents.
  Call poll requesting POLLERR or POLLPRI (so select/exceptfds works)
  When poll returns,
     close the file and go to top of loop.
   or lseek to start of file and go back to the 'read'.

Events are signaled by an object manager calling
   sysfs_notify(kobj, dir, attr);

If the dir is non-NULL, it is used to find a subdirectory which
contains the attribute (presumably created by sysfs_create_group).

This has a cost of one int  per attribute, one wait_queuehead per kobject,
one int per open file.

The name "sysfs_notify" may be confused with the inotify
functionality.  Maybe it would be nice to support inotify for sysfs
attributes as well?

This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action
to be pollable

David Brownell [Sun, 2 Apr 2006 18:20:15 +0000]
[PATCH] USB: usbtest: scatterlist OUT data pattern testing

Previously, scatterlist tests didn't write patterned data.  Given how many
corner cases are addresed by them, this was a significant gap in Linux-USB
test coverage.  Moreover, when peripherals checked for correct data patterns,
false error reports would drown out the true ones.

This adds the pattern on the way OUT from the host, so scatterlist tests can
now be used to uncover bugs like host TX or peripheral RX paths failing for
back-to-back short packets.  It's easy enough to get an error there with at
least one of the {DMA,PIO}{RX,TX} code paths, or run into hardware races
that need to be defended against.

Note this patch doesn't add checking for correct data patterns on the way
IN from peripherals, just a FIXME for later.
