2012-01-17net: WARN if skb_checksum_help() is called on skb requiring segmentationBen Hutchings
skb_checksum_help() has never done anything useful with skbs that require segmentation. Setting skb->ip_summed = CHECKSUM_NONE makes them invalid and provokes a later WARNing in skb_gso_segment(). Passing such an skb to skb_checksum_help() indicates a bug, so we should warn about it immediately. Move the warning from skb_gso_segment() into a shared function, and add gso_type and gso_size to it. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* 'for-linus' of git://git.kernel.dk/linux-block: cfq-iosched: fix use-after-free of cfqq
2012-01-17cfq-iosched: fix use-after-free of cfqqJens Axboe
With the changes in life time management between the cfq IO contexts and the cfq queues, we now risk having cfqd->active_queue being freed when cfq_slice_expired() is being called. cfq_preempt_queue() caches this queue and uses it after calling said function, causing a use-after-free condition. This triggers the following oops, when cfqq_type() attempts to dereference it: BUG: unable to handle kernel paging request at ffff8800746c4f0c IP: [<ffffffff81266d59>] cfqq_type+0xb/0x20 PGD 18d4063 PUD 1fe15067 PMD 1ffb9067 PTE 80000000746c4160 Oops: 0000 [#1] SMP DEBUG_PAGEALLOC CPU 3 Modules linked in: Pid: 1, comm: init Not tainted 3.2.0-josef+ #367 Bochs Bochs RIP: 0010:[<ffffffff81266d59>] [<ffffffff81266d59>] cfqq_type+0xb/0x20 RSP: 0018:ffff880079c11778 EFLAGS: 00010046 RAX: 0000000000000000 RBX: ffff880076f3df08 RCX: 0000000000000000 RDX: 0000000000000006 RSI: ffff880074271888 RDI: ffff8800746c4f08 RBP: ffff880079c11778 R08: 0000000000000078 R09: 0000000000000001 R10: 09f911029d74e35b R11: 09f911029d74e35b R12: ffff880076f337f0 R13: ffff8800746c4f08 R14: ffff8800746c4f08 R15: 0000000000000002 FS: 00007f62fd44f700(0000) GS:ffff88007cd80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffff8800746c4f0c CR3: 0000000076c21000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process init (pid: 1, threadinfo ffff880079c10000, task ffff880079c0a040) Stack: ffff880079c117c8 ffffffff812683d8 ffff880079c117a8 ffffffff8125de43 ffff8800744fcf48 ffff880074b43e98 ffff8800770c8828 ffff880074b43e98 0000000000000003 0000000000000000 ffff880079c117f8 ffffffff81254149 Call Trace: [<ffffffff812683d8>] cfq_insert_request+0x3f5/0x47c [<ffffffff8125de43>] ? blk_recount_segments+0x20/0x31 [<ffffffff81254149>] __elv_add_request+0x1ca/0x200 [<ffffffff8125aa99>] blk_queue_bio+0x2ef/0x312 [<ffffffff81258f7b>] generic_make_request+0x9f/0xe0 [<ffffffff8125907b>] submit_bio+0xbf/0xca [<ffffffff81136ec7>] submit_bh+0xdf/0xfe [<ffffffff81176d04>] ext3_bread+0x50/0x99 [<ffffffff811785b3>] dx_probe+0x38/0x291 [<ffffffff81178864>] ext3_dx_find_entry+0x58/0x219 [<ffffffff81178ad5>] ext3_find_entry+0xb0/0x406 [<ffffffff8110c4d5>] ? cache_alloc_debugcheck_after.isra.46+0x14d/0x1a0 [<ffffffff8110cfbd>] ? kmem_cache_alloc+0xef/0x191 [<ffffffff8117a330>] ext3_lookup+0x39/0xe1 [<ffffffff81119461>] d_alloc_and_lookup+0x45/0x6c [<ffffffff8111ac41>] do_lookup+0x1e4/0x2f5 [<ffffffff8111aef6>] link_path_walk+0x1a4/0x6ef [<ffffffff8111b557>] path_lookupat+0x59/0x5ea [<ffffffff8127406c>] ? __strncpy_from_user+0x30/0x5a [<ffffffff8111bce0>] do_path_lookup+0x23/0x59 [<ffffffff8111cfd6>] user_path_at_empty+0x53/0x99 [<ffffffff8107b37b>] ? remove_wait_queue+0x51/0x56 [<ffffffff8111d02d>] user_path_at+0x11/0x13 [<ffffffff811141f5>] vfs_fstatat+0x3a/0x64 [<ffffffff8111425a>] vfs_stat+0x1b/0x1d [<ffffffff81114359>] sys_newstat+0x1a/0x33 [<ffffffff81060e12>] ? task_stopped_code+0x42/0x42 [<ffffffff815d6712>] system_call_fastpath+0x16/0x1b Code: 89 e6 48 89 c7 e8 fa ca fe ff 85 c0 74 06 4c 89 2b 41 b6 01 5b 44 89 f0 41 5c 41 5d 41 5e 5d c3 55 48 89 e5 66 66 66 66 90 31 c0 <8b> 57 04 f6 c6 01 74 0b 83 e2 20 83 fa 01 19 c0 83 c0 02 5d c3 RIP [<ffffffff81266d59>] cfqq_type+0xb/0x20 RSP <ffff880079c11778> CR2: ffff8800746c4f0c Get rid of the caching of cfqd->active_queue, and reorder the check so that it happens before we expire the active queue.

2012-01-17intel idle: Make idle driver more robustThomas Renninger
kvm -cpu host passes the original cpuid info to the guest. Latest kvm version seem to return true for mwait_leaf cpuid function on recent Intel CPUs. But it does not return mwait C-states (mwait_substates), instead zero is returned. While real CPUs seem to always return non-zero values, the intel idle driver should not get active in kvm (mwait_substates == 0) case and bail out. Otherwise a Null pointer exception will happen later when the cpuidle subsystem tries to get active: [0.984807] BUG: unable to handle kernel NULL pointer dereference at (null) [0.984807] IP: [<(null)>] (null) ...

2012-01-17intel_idle: remove redundant local_irq_disable() callYanmin Zhang
irq disabling happens earlier in process_32.c:cpu_idle. Basically, cpuidle_state->enter is called, cpu irq is disabled. cpuidle_state->enter would turn on irq when exiting. intel_idle doesn't follow this assumption. Although it doesn't cause real issue, it misleads developers. Remove the call to local_irq_disable() at entry.

2012-01-17[media] dvb_frontend: Don't call get_frontend() if idleMauro Carvalho Chehab
If the frontend is in idle state, don't call get_frontend. Calling get_frontend() when the device is not tuned may result in wrong parameters to be returned to the userspace. I was tempted to not call get_frontend() at all, except inside the dvb frontend thread, but this won't work for all cases. The ISDB-T specs (ABNT NBR 15601 and ARIB STD-B31) allow the broadcaster to dynamically change the channel specs at runtime. That means that an ISDB-T optimized application may want/need to monitor the TMCC tables, decoded at the frontends via get_frontend call. So, let's do the simpler change here. Eventually, the logic could be changed to work only if the device is tuned and has lock, but, even so, the lock is also standard-dependent. For ISDB-T, the right lock to wait is that the demod has TMCC lock. So, drivers may need to implement some logic to detect if the get_frontend info was retrieved or not.

2012-01-17Revert "capabitlies: ns_capable can use the cap helpers rather than lsm call"Linus Torvalds
This reverts commit d2a7009f0bb03fa22ad08dd25472efa0568126b9. J. R. Okajima explains: "After this commit, I am afraid access(2) on NFS may not work correctly. The scenario based upon my guess. - access(2) overrides the credentials. - calls inode_permission() -- ... -- generic_permission() -- ns_capable(). - while the old ns_capable() calls security_capable(current_cred()), the new ns_capable() calls has_ns_capability(current) -- security_capable(__task_cred(t)). current_cred() returns current->cred which is effective (overridden) credentials, but __task_cred(current) returns current->real_cred (the NFSD's credential).

2012-01-17[media] DocBook/dvbproperty.xml: Remove DTV_MODULATION from ISDB-TMauro Carvalho Chehab
On ISDB-T, each layer can have its own independent modulation, applied to the carriers that belong to the segments associated with them. So, there's no sense to define a global modulation parameter. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-01-17[media] DocBook/dvbproperty.xml: Fix ISDB-T delivery system parametersMauro Carvalho Chehab
The ISDB-T differs on its way to implement the hierarchical transmissions: instead of using a low-priority/high-priority FEC codes, it does that by using different layers, each layer with their groups of segments. So, those parameters don't make sense for ISDB-T. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-01-17ACPI: processor: fix acpi_get_cpuid for UP processorLin Ming
For UP processor, it is likely that no _MAT method or MADT table defined. So currently acpi_get_cpuid(...) always return -1 for UP processor. This is wrong. It should return valid value for CPU0. In the other hand, BIOS may define multiple CPU handles even for UP processor, for example Scope (_PR) { Processor (CPU0, 0x00, 0x00000410, 0x06) {} Processor (CPU1, 0x01, 0x00000410, 0x06) {} Processor (CPU2, 0x02, 0x00000410, 0x06) {} Processor (CPU3, 0x03, 0x00000410, 0x06) {} } We should only return valid value for CPU0's acpi handle. And return invalid value for others. http://marc.info/?t=132329819900003&r=1&w=2 Cc: stable@vger.kernel.org Reported-and-tested-by: wallak@free.fr Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2012-01-17intel_idle: fix API misuseShaohua Li
smp_call_function() only lets all other CPUs execute a specific function, while we expect all CPUs do in intel_idle. Without the fix, we could have one cpu which has auto_demotion enabled or has no broadcast timer setup. Usually we don't see impact because auto demotion just harms power and the intel_idle init is called in CPU 0, where boradcast timer delivers interrupt, but this still could be a problem.

2012-01-17netfilter: ipset: dumping error triggered removing references twiceJozsef Kadlecsik
If there was a dumping error in the middle, the set-specific variable was not zeroed out and thus the 'done' function of the dumping wrongly tried to release the already released reference of the set. The already released reference was caught by __ip_set_put and triggered a kernel BUG message. Reported by Jean-Philippe Menil.
