2012-02-03usb: ch9.h: usb_endpoint_maxp() uses __le16_to_cpu()Kuninori Morimoto1-1/+1
The usb/ch9.h will be installed to /usr/include/linux, and be used from user space. But le16_to_cpu() is only defined for kernel code. Without this patch, user space compile will be broken.

2012-02-03perf: Remove deprecated WARN_ON_ONCE()Stephane Eranian3-6/+0
With the new throttling/unthrottling code introduced with commit: e050e3f0a71b ("perf: Fix broken interrupt rate throttling") we occasionally hit two WARN_ON_ONCE() checks in: - intel_pmu_pebs_enable() - intel_pmu_lbr_enable() - x86_pmu_start() The assertions are no longer problematic. There is a valid path where they can trigger but it is harmless. The assertion can be triggered with: $ perf record -e instructions:pp .... Leading to paths: intel_pmu_pebs_enable intel_pmu_enable_event x86_perf_event_set_period x86_pmu_start perf_adjust_freq_unthr_context perf_event_task_tick scheduler_tick And: intel_pmu_lbr_enable intel_pmu_enable_event x86_perf_event_set_period x86_pmu_start perf_adjust_freq_unthr_context. perf_event_task_tick scheduler_tick cpuc->enabled is always on because when we get to perf_adjust_freq_unthr_context() the PMU is not totally disabled. Furthermore when we need to adjust a period, we only stop the event we need to change and not the entire PMU. Thus, when we re-enable, cpuc->enabled is already set. Note that when we stop the event, both pebs and lbr are stopped if necessary (and possible).

2012-02-02drivers/tty/vt/vt_ioctl.c: fix KDFONTOP 32bit compatibility layerSamuel Thibault1-1/+0
KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland with a 64bit kernel if the font width is not 8. This is because the compatibility layer introduced by e9216651 ("tty: handle VT specific compat ioctls in vt driver") forces the addition of the KD_FONT_FLAG_OLD flag, which makes con_font_get return EIO in such case. This flag should *not* be set for KDFONTOP, since it's actually the whole point of this flag (see comment in con_font_set for instance).

2012-02-02rbd: fix safety of rbd_put_client()Alex Elder1-2/+4
The rbd_client structure uses a kref to arrange for cleaning up and freeing an instance when its last reference is dropped. The cleanup routine is rbd_client_release(), and one of the things it does is delete the rbd_client from rbd_client_list. It acquires node_lock to do so, but the way it is done is still not safe. The problem is that when attempting to reuse an existing rbd_client, the structure found might already be in the process of getting destroyed and cleaned up. Here's the scenario, with "CLIENT" representing an existing rbd_client that's involved in the race: Thread on CPU A | Thread on CPU B --------------- | --------------- rbd_put_client(CLIENT) | rbd_get_client() kref_put() | (acquires node_lock) kref->refcount becomes 0 | __rbd_client_find() returns CLIENT calls rbd_client_release() | kref_get(&CLIENT->kref); | (releases node_lock) (acquires node_lock) | deletes CLIENT from list | ...and starts using CLIENT... (releases node_lock) | and frees CLIENT | <-- but CLIENT gets freed here Fix this by having rbd_put_client() acquire node_lock. The result could still be improved, but at least it avoids this problem. Signed-off-by: Alex Elder <[email protected]> Signed-off-by: Sage Weil <[email protected]>

2012-02-02ceph: create a new session lock to avoid lock inversionAlex Elder4-9/+14
Lockdep was reporting a possible circular lock dependency in dentry_lease_is_valid(). That function needs to sample the session's s_cap_gen and and s_cap_ttl fields coherently, but needs to do so while holding a dentry lock. The s_cap_lock field was being used to protect the two fields, but that can't be taken while holding a lock on a dentry within the session. In most cases, the s_cap_gen and s_cap_ttl fields only get operated on separately. But in three cases they need to be updated together. Implement a new lock to protect the spots updating both fields atomically is required. Signed-off-by: Alex Elder <[email protected]> Reviewed-by: Sage Weil <[email protected]>

2012-02-02ceph: initialize client debugfs outside of monc->mutexSage Weil2-3/+12
Initializing debufs under monc->mutex introduces a lock dependency for sb->s_type->i_mutex_key, which (combined with several other dependencies) leads to an annoying lockdep warning. There's no particular reason to do the debugfs setup under this lock, so move it out. It used to be the case that our first monmap could come from the OSD; that is no longer the case with recent servers, so we will reliably set up the client entry during the initial authentication. We don't have to worry about racing with debugfs teardown by ceph_debugfs_client_cleanup() because ceph_destroy_client() calls ceph_msgr_flush() first, which will wait for the message dispatch work to complete (and the debugfs init to complete).

The Netlogic XLP SoC's on-chip USB controller appears as a PCI USB device, but does not need the EHCI/OHCI handoff done in usb/host/pci-quirks.c. The pci-quirks.c is enabled for all vendors and devices, and is enabled if USB and PCI are configured. If we do not skip the qurik handling on XLP, the readb() call in ehci_bios_handoff() will cause a crash since byte access is not supported for EHCI registers in XLP.

2012-02-02caif: Bugfix list_del_rcu race in cfmuxl_ctrlcmd.[email protected]1-9/+3
Always use cfmuxl_remove_uplayer when removing a up-layer. cfmuxl_ctrlcmd() can be called independently and in parallel with cfmuxl_remove_uplayer(). The race between them could cause list_del_rcu to be called on a node which has been already taken out from the list. That lead to a (rare) crash on accessing poisoned node->prev inside list_del_rcu. This fix ensures that deletion are done holding the same lock. Reported-by: Dmitry Tarnyagin <[email protected]> Signed-off-by: Sjur Brændeland <[email protected]> Signed-off-by: David S.

2012-02-02net/hyperv: fix the issue that large packets be dropped under bridgeWei Yongjun1-0/+19
The packets with size larger than 1452 will be dropped by bridge which with two hyperv netdevice ports. This cause by hyperv netvsc driver always copy the trailer padding to the data packet, and then the skb received from netdevice may include wrong skb->len (20 bytes larger than the real size normally). The captured packet may like this: Ethernet II, Src: Microsof_00:00:07 (00:15:5d:00:00:07), Dst: HewlettP_00:00:4e (00:1f:29:00:00:4e) Destination: HewlettP_e6:00:4e (00:1f:29:00:00:4e) Source: Microsof_f6:6d:07 (00:15:5d:f6:6d:07) Type: IP (0x0800) Trailer: 1415161718191A1B1C1D1E1F20212223 Frame check sequence: 0x24252627 [incorrect, should be 0x7c2e5a5e] The following command help to reproduction it, and the ping ICMP packets will be dropped by bridge. $ ping ip -s 1453 This patch fixed it by removing the trailer padding from the data packet.

2012-02-02driver core: cpu: remove kernel warning when removing a cpuGreg Kroah-Hartman1-0/+20
With the movement of the cpu sysdev code to be real stuct devices, now when we remove a cpu from the system, the driver core rightfully complains that there is not a release method for this device. For now, paper over this issue by quieting the driver core, but comment this in detail. This will be resolved in future kernels to be solved properly.

2012-02-02ARM: 7302/1: Add TLB flushing for both entries in a PMDCatalin Marinas1-1/+9
Linux uses two PMD entries for a PTE with the classic page table format, covering 2MB range. However, the __pte_free_tlb() function only adds a single TLB flush corresponding to 1MB range covering 'addr'. On Cortex-A15, level 1 entries can be cached by the TLB independently of the level 2 entries and without additional flushing a PMD entry would be left pointing at the wrong PTE. The patch limits the TLB flushing range to two 4KB pages around the 1MB boundary within PMD. Signed-off-by: Catalin Marinas <[email protected]> Signed-off-by: Russell King <[email protected]>

Commit 89d6c0b5 ("perf, arch: Add generic NODE cache events") added empty NODE event definitions for the ARM PMU implementations. This was merged along with Cortex-A5 and Cortex-A15 PMU support, so they missed out on the original patch. This patch adds the empty definitions to Cortex-A5 and Cortex-A15.

2012-02-02ARM: 7308/1: vfp: flush thread hwstate before copying ptrace registersWill Deacon1-1/+1
If we are context switched whilst copying into a thread's vfp_hard_struct then the partial copy may be corrupted by the VFP context switching code (see "ARM: vfp: flush thread hwstate before restoring context from sigframe"). This patch updates the ptrace VFP set code so that the thread state is flushed before the copy, therefore disabling VFP and preventing corruption from occurring.
