V4L/DVB (5074): Some fixes at stream waitqueue on vivi

There are several potential troubles on vivi waitqueue code:
- Watchdog timer should be reset at every received frame;
- Watchdog timer should be reset at the beginning of vivi_thread();
- Checks for errors when creating a newer thread with kernel_thread();
- Wake up vivi_thread() after creating it.

David Brownell [Tue, 20 Feb 2007 21:58:16 +0000]
[PATCH] remove modpost false warnings on ARM

This patch stops "modpost" from issuing erroneous modpost warnings on ARM
builds, which it's been doing since since maybe last summer.  A canonical
example would be driver method table entries:

  WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove
from .data after '$d' (at offset 0x4)

That "$d" symbol is generated by tools conformant with ARM ABI specs; in
this case it's a symbol **in the middle of** a "<name>_driver" struct.

The erroneous warnings appear to be issued because "modpost" whitelists
references from "<name>_driver" data into init and exit sections ...  but
doesn't know should also include those "$d" mapping symbols, which are not
otherwise associated with "<name>_driver" symbols.

This patch prevents the modpost symbol lookup code from ever returning
those mapping symbols, so it will return a whitelisted symbol instead.
Then things work as expected.

Now to revert various code-bloating "fixes" that got merged because of this
modpost bug....

  - fixes comment and includes in gpio.h
  - replaces the gpio_set/get_value macros with inline

[PATCH] at91_rtc updates

Various bug fixes to the at91rm9200 RTC:

 - alarm:  setalarm() should pay attention to the "enabled" flag

 - init:  cleaner handling of the wakeup flags, which cpu init should
   really have set up.  Doing it here is just a workaround.

 - linkage:  since the at91_rtc driver probe() routine is in the init
   section, it should use platform_driver_probe() instead of leaving
   that pointer around in the driver struct after init section removal.

 - linkage:  likewise, remove() belongs in the exit section.

Among other things, the init and alarm changes ensure that this driver
handles the new sysfs "wakealarm" attribute properly.

[PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixes

Some rtc-sa1100 bugfixes:

 - The read_alarm() method reports the rtc_wkalrm.enabled field properly.
   This patch is already in the handhelds.org tree.

 - And the set_alarm() method now handles that flag correctly, rather than
   making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
   warning messages.  (Those calls are best made in suspend/resume methods.)

Note that while this SA1100/PXA RTC is fully capable of waking those ARM
processors from sleep states, that mechanism isn't properly supported on
either processor family, or in this driver.  Some boards have board-specific
PM glue providing partial workarounds for the weak generic PM support.

This problem was identified and fixed some time ago by Jeff Moyer but it fell
through the cracks somehow.

It is possible that a user space application could remove and re-create a
directory during a request.  To avoid returning a failure from lookup
incorrectly when our current dentry is unhashed we need to check if another
positive, hashed dentry matching this one exists and if so return it instead
of a fail.

Ian Kent [Tue, 20 Feb 2007 21:58:10 +0000]
[PATCH] autofs4: fix another race between mount and expire

Jeff Moyer has identified a race between mount and expire.

What happens is that during an expire the situation can arise that a directory
is removed and another lookup is done before the expire issues a completion
status to the kernel module.  In this case, since the the lookup gets a new
dentry, it doesn't know that there is an expire in progress and when it posts
its mount request, matches the existing expire request and waits for its
completion.  ENOENT is then returned to user space from lookup (as the dentry
passed in is now unhashed) without having performed the mount request.

The solution used here is to keep track of dentrys in this unhashed state and
reuse them, if possible, in order to preserve the flags.  Additionally, this
infrastructure will provide the framework for the reintroduction of caching of
mount fails removed earlier in development.

[PATCH] fs: fix nobh data leak

nobh_prepare_write leaks data similarly to how simple_prepare_write did. Fix
by not marking the page uptodate until nobh_commit_write time. Again, this
could break weird use-cases, but none appear to exist in the tree.

We can safely remove the set_page_dirty, because as the comment says,
nobh_commit_write does set_page_dirty. If a filesystem wants to allocate
backing store for a page dirtied via mmap, page_mkwrite is the suggested
approach.

Nick Piggin [Tue, 20 Feb 2007 21:58:08 +0000]
[PATCH] fs: fix libfs data leak

simple_prepare_write leaks uninitialised kernel data.  This happens because
the it leaves an uninitialised "hole" over the part of the page that the
write is expected to go to.  This is fine, but it then marks the page
uptodate, which means a concurrent read can come in and copy the
uninitialised memory into userspace before it written to.

Fix it by simply marking it uptodate in simple_commit_write instead, after
the hole has been filled in.  This could theoretically break an fs that
uses simple_prepare_write and not simple_commit_write, and that relies on
the incorrect simple_prepare_write behaviour.  Luckily, none of those
exists in the tree.

The problem comes when ks0108/cfag12864b are built-in and no parallel port is
present.  ks0108_init() is called first, as it should be, but fails to load
(as there is no parallel port to use).

After that, cfag12864b_init() gets called, without knowing anything about
ks0108 failed, and calls ks0108_writecontrol(), which dereferences an
uninitialized pointer.

Init order is OK, I think.  The problem is how to stop cfag12864b_init() being
called if ks0108 failed to load.  modprobe does it for us, but, how when
built-in?

[PATCH] fault injection: split up stacktrace filter Kconfig option

There is no prompt for CONFIG_STACKTRACE, so FAULT_INJECTION cannot be
selected without LOCKDEP enabled.  (found by Paolo 'Blaisorblade'
Giarrusso)

In order to fix such broken Kconfig dependency, this patch splits up the
stacktrace filter support for fault injection by new Kconfig option, which
enables to use fault injection on the architecture which doesn't have
general stacktrace support.

It also lists address of the instruction,its symbolic name(function name +
offset) and the module name.  One can access this file through
/sys/kernel/debug/kprobes/list.

messing around with the page buffers, and they subsequently get freed.

12 years ago[PATCH] shm: make sysv ipc shared memory use stacked files
Eric W. Biederman [Tue, 20 Feb 2007 21:57:53 +0000]
[PATCH] shm: make sysv ipc shared memory use stacked files

The current ipc shared memory code runs into several problems because it
does not quite use files like the rest of the kernel.  With the option of
backing ipc shared memory with either hugetlbfs or ordinary shared memory
the problems got worse.  With the added support for ipc namespaces things
behaved so unexpected that we now have several bad namespace reference
counting bugs when using what appears at first glance to be a reasonable
idiom.

So to attack these problems and hopefully make the code more maintainable
this patch simply uses the files provided by other parts of the kernel and
builds it's own files out of them.  The shm files are allocated in do_shmat
and freed when their reference count drops to zero with their last unmap.
The file and vm operations that we don't want to implement or we don't
implement completely we just delegate to the operations of our backing
file.

This means that we now get an accurate shm_nattch count for we have a
hugetlbfs inode for backing store, and the shm accounting of last attach
and last detach time work as well.

This means that getting a reference to the ipc namespace when we create the
file and dropping the referenece in the release method is now safe and
correct.

This means we no longer need a special case for clearing VM_MAYWRITE
as our file descriptor now only has write permissions when we have
requested write access when calling shmat.  Although VM_SHARED is now
cleared as well which I believe is harmless and is mostly likely a
minor bug fix.

By using the same set of operations for both the hugetlb case and regular
shared memory case shmdt is not simplified and made slightly more correct
as now the test "vma->vm_ops == &shm_vm_ops" is 100% accurate in spotting
all shared memory regions generated from sysvipc shared memory.

12 years ago[PATCH] slab: reduce size of alien cache to cover only possible nodes
Christoph Lameter [Tue, 20 Feb 2007 21:57:52 +0000]
[PATCH] slab: reduce size of alien cache to cover only possible nodes

The alien cache is a per cpu per node array allocated for every slab on the
system.  Currently we size this array for all nodes that the kernel does
support.  For IA64 this is 1024 nodes.  So we allocate an array with 1024
objects even if we only boot a system with 4 nodes.

This patch uses "nr_node_ids" to determine the number of possible nodes
supported by a hardware configuration and only allocates an alien cache
sized for possible nodes.

The initialization of nr_node_ids occurred too late relative to the bootstrap
of the slab allocator and so I moved the setup_nr_node_ids() into
free_area_init_nodes().

Christoph Lameter [Tue, 20 Feb 2007 21:57:51 +0000]
[PATCH] Convert highest_possible_processor_id to nr_cpu_ids

We frequently need the maximum number of possible processors in order to
allocate arrays for all processors.  So far this was done using
highest_possible_processor_id().  However, we do need the number of
processors not the highest id.  Moreover the number was so far dynamically
calculated on each invokation.  The number of possible processors does not
change when the system is running.  We can therefore calculate that number
once.

12 years ago[PATCH] Replace highest_possible_node_id() with nr_node_ids
Christoph Lameter [Tue, 20 Feb 2007 21:57:51 +0000]
[PATCH] Replace highest_possible_node_id() with nr_node_ids

highest_possible_node_id() is currently used to calculate the last possible
node idso that the network subsystem can figure out how to size per node
arrays.

I think having the ability to determine the maximum amount of nodes in a
system at runtime is useful but then we should name this entry
correspondingly, it should return the number of node_ids, and the the value
needs to be setup only once on bootup.  The node_possible_map does not
change after bootup.

This patch introduces nr_node_ids and replaces the use of
highest_possible_node_id().  nr_node_ids is calculated on bootup when the
page allocators pagesets are initialized.

Aculab E1/T1 PMXc cPCI carrier card cards present a natsemi on the cPCI
bus with an oversized EEPROM using a direct MII<->MII connection with no
PHY.  This patch adds a new device table entry supporting these cards.

12 years agonatsemi: Add support for using MII port with no PHY
Mark Brown [Mon, 19 Feb 2007 20:15:39 +0000]
natsemi: Add support for using MII port with no PHY

This patch provides code paths which allow the natsemi driver to use the
external MII port on the chip but ignore any PHYs that may be attached to it.
The link state will be left as it was when the driver started and can be
configured via ethtool.  Any PHYs that are present can be accessed via the MII
ioctl()s.

This is useful for systems where the device is connected without a PHY
or where either information or actions outside the scope of the driver
are required in order to use the PHYs.

skge: race with workq and RTNL

If a workqueue function that needs RTNL is running when skge_down
is called then a deadlock is possible. Fix by only clearing the timer,
and handling the flush_scheduled_work on removal. This work queue is only
ever used for the old fiber based boards.
