2010-02-10powerpc: Fix address masking bug in hpte_need_flush()David Gibson
Commit f71dc176aa06359681c30ba6877ffccab6fba3a6 'Make hpte_need_flush() correctly mask for multiple page sizes' introduced bug, which is triggered when a kernel with a 64k base page size is run on a system whose hardware does not 64k hash PTEs. In this case, we emulate 64k pages with multiple 4k hash PTEs, however in hpte_need_flush() we incorrectly only mask the hardware page size from the address, instead of the logical page size. This causes things to go wrong when we later attempt to iterate through the hardware subpages of the logical page. This patch corrects the error. It has been tested on pSeries bare metal by Michael Neuling. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2010-02-10md: fix some lockdep issues between md and sysfs.NeilBrown
====== This fix is related to http://bugzilla.kernel.org/show_bug.cgi?id=15142 but does not address that exact issue. ====== sysfs does like attributes being removed while they are being accessed (i.e. read or written) and waits for the access to complete. As accessing some md attributes takes the same lock that is held while removing those attributes a deadlock can occur. This patch addresses 3 issues in md that could lead to this deadlock. Two relate to calling flush_scheduled_work while the lock is held. This is probably a bad idea in general and as we use schedule_work to delete various sysfs objects it is particularly bad. In one case flush_scheduled_work is called from md_alloc (called by md_probe) called from do_md_run which holds the lock. This call is only present to ensure that ->gendisk is set. However we can be sure that gendisk is always set (though possibly we couldn't when that code was originally written. This is because do_md_run is called in three different contexts: 1/ from md_ioctl. This requires that md_open has succeeded, and it fails if ->gendisk is not set. 2/ from writing a sysfs attribute. This can only happen if the mddev has been registered in sysfs which happens in md_alloc after ->gendisk has been set. 3/ from autorun_array which is only called by autorun_devices, which checks for ->gendisk to be set before calling autorun_array. So the call to md_probe in do_md_run can be removed, and the check on ->gendisk can also go. In the other case flush_scheduled_work is being called in do_md_stop, purportedly to wait for all md_delayed_delete calls (which delete the component rdevs) to complete. However there really isn't any need to wait for them - they have already been disconnected in all important ways. The third issue is that raid5->stop() removes some attribute names while the lock is held. There is already some infrastructure in place to delay attribute removal until after the lock is released (using schedule_work). So extend that infrastructure to remove the raid5_attrs_group. This does not address all lockdep issues related to the sysfs "s_active" lock. The rest can be address by splitting that lockdep context between symlinks and non-symlinks which hopefully will happen.

2010-02-09md: fix 'degraded' calculation when starting a reshape.NeilBrown
This code was written long ago when it was not possible to reshape a degraded array. Now it is so the current level of degraded-ness needs to be taken in to account. Also newly addded devices should only reduce degradedness if they are deemed to be in-sync. In particular, if you convert a RAID5 to a RAID6, and increase the number of devices at the same time, then the 5->6 conversion will make the array degraded so the current code will produce a wrong value for 'degraded' - "-1" to be precise. If the reshape runs to completion end_reshape will calculate a correct new value for 'degraded', but if a device fails during the reshape an incorrect decision might be made based on the incorrect value of "degraded". This patch is suitable for 2.6.32-stable and if they are still open, 2.6.31-stable and 2.6.30-stable as well.

2010-02-08Revert "nfsd4: fix error return when pseudoroot missing"J. Bruce Fields
Commit f39bde24b275ddc45d fixed the error return from PUTROOTFH in the case where there is no pseudofilesystem. This is really a case we shouldn't hit on a correctly configured server: in the absence of a root filehandle, there's no point accepting version 4 NFS rpc calls at all. But the shared responsibility between kernel and userspace here means the kernel on its own can't eliminate the possiblity of this happening. And we have indeed gotten this wrong in distro's, so new client-side mount code that attempts to negotiate v4 by default first has to work around this case. Therefore when commit f39bde24b275ddc45d arrived at roughly the same time as the new v4-default mount code, which explicitly checked only for the previous error, the result was previously fine mounts suddenly failing. We'll fix both sides for now: revert the error change, and make the client-side mount workaround more robust. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

2010-02-08netfilter: nf_conntrack: fix hash resizing with namespacesPatrick McHardy
As noticed by Jon Masters <jonathan@jonmasters.org>, the conntrack hash size is global and not per namespace, but modifiable at runtime through /sys/module/nf_conntrack/hashsize. Changing the hash size will only resize the hash in the current namespace however, so other namespaces will use an invalid hash size. This can cause crashes when enlarging the hashsize, or false negative lookups when shrinking it. Move the hash size into the per-namespace data and only use the global hash size to initialize the per-namespace value when instanciating a new namespace. Additionally restrict hash resizing to init_net for now as other namespaces are not handled currently. Cc: stable@kernel.org Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2010-02-08netfilter: nf_conntrack: per netns nf_conntrack_cachepEric Dumazet
nf_conntrack_cachep is currently shared by all netns instances, but because of SLAB_DESTROY_BY_RCU special semantics, this is wrong. If we use a shared slab cache, one object can instantly flight between one hash table (netns ONE) to another one (netns TWO), and concurrent reader (doing a lookup in netns ONE, 'finding' an object of netns TWO) can be fooled without notice, because no RCU grace period has to be observed between object freeing and its reuse. We dont have this problem with UDP/TCP slab caches because TCP/UDP hashtables are global to the machine (and each object has a pointer to its netns). If we use per netns conntrack hash tables, we also *must* use per netns conntrack slab caches, to guarantee an object can not escape from one namespace to another one.

2010-02-08netfilter: nf_conntrack: fix memory corruption with multiple namespacesPatrick McHardy
As discovered by Jon Masters <jonathan@jonmasters.org>, the "untracked" conntrack, which is located in the data section, might be accidentally freed when a new namespace is instantiated while the untracked conntrack is attached to a skb because the reference count it re-initialized. The best fix would be to use a seperate untracked conntrack per namespace since it includes a namespace pointer. Unfortunately this is not possible without larger changes since the namespace is not easily available everywhere we need it. For now move the untracked conntrack initialization to the init_net setup function to make sure the reference count is not re-initialized and handle cleanup in the init_net cleanup function to make sure namespaces can exit properly while the untracked conntrack is in use in other namespaces.

2010-02-08cifs: fix dentry hash calculation for case-insensitive mountsJeff Layton
case-insensitive mounts shouldn't use full_name_hash(). Make sure we use the parent dentry's d_hash routine when one is set. Reported-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com> Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2010-02-08V4L/DVB: dvb-core: fix initialization of feeds list in demux filterFrancesco Lavra
A DVB demultiplexer device can be used to set up either a PES filter or a section filter. In the former case, the ts field of the feed union of struct dmxdev_filter is used, in the latter case the sec field of the same union is used. The ts field is a struct list_head, and is currently initialized in the open() method of the demux device. When for a given demuxer a section filter is set up, the sec field is played with, thus if a PES filter needs to be set up after that the ts field will be corrupted, causing a kernel oops. This fix moves the list head initialization to dvb_dmxdev_pes_filter_set(), so that the ts field is properly initialized every time a PES filter is set up.
