2012-06-14staging: gdm72xx: Release netlink socket properlyBen Chan
This patch modifies the gdm72xx driver to properly release a netlink socket using netlink_kernel_release. It fixes the following kernel crash, which occurs after repeatedly suspending and resuming a system. kernel BUG at /home/benchan/trunk/src/third_party/kernel/files/mm/slub.c:3471! invalid opcode: 0000 [#1] SMP CPU 2 Modules linked in: asix usbnet snd_hda_codec_hdmi snd_hda_codec_cirrus i2c_dev uinput snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_timer bluetooth snd_page_alloc fuse aesni_intel cryptd isl29018(C) aes_x86_64 industrialio(C) memconsole nm10_gpio rtc_cmos nf_conntrack_ipv6 nf_defrag_ipv6 r8169 ath9k mac80211 ip6table_filter ath9k_common ath9k_hw ath cfg80211 xt_mark ip6_tables uvcvideo videobuf2_core videodev videobuf2_vmalloc videobuf2_memops gdmwm(C) joydev Pid: 3125, comm: kworker/u:30 Tainted: G WC 3.4.0 #1 RIP: 0010:[<ffffffff810cda19>] [<ffffffff810cda19>] kfree+0x67/0xca RSP: 0018:ffff880134977d60 EFLAGS: 00010246 RAX: 4000000000000400 RBX: ffffffff818832a0 RCX: 0000000000000000 RDX: 4000000000000000 RSI: 0000000000000000 RDI: ffffffff818832a0 RBP: ffff880134977d80 R08: 00000000ffffffff R09: ffffea00000620c0 R10: ffffffff8111b729 R11: ffff880149fb3840 R12: ffffffff81a08840 R13: ffffffff813f5bc3 R14: ffffffff8138ed84 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff88014fb00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007f7cad963110 CR3: 000000000180b000 CR4: 00000000000407e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kworker/u:30 (pid: 3125, threadinfo ffff880134976000, task ffff8801330647e0) Stack: 0000000000000002 ffffffff818832a0 ffffffff81a08840 ffff880134977df0 ffff880134977da0 ffffffff813f5bc3 ffff880134977df0 ffffffff81883250 ffff880134977dd0 ffffffff8138e64c 0000000180150010 ffffffff81883250 Call Trace: [<ffffffff813f5bc3>] ipv4_sysctl_exit_net+0x23/0x27 [<ffffffff8138e64c>] ops_exit_list+0x27/0x50 [<ffffffff8138ee72>] cleanup_net+0xee/0x17c [<ffffffff81040c64>] process_one_work+0x199/0x2b8 [<ffffffff810416e4>] worker_thread+0x13c/0x222 [<ffffffff810415a8>] ? manage_workers.isra.26+0x171/0x171 [<ffffffff8104506d>] kthread+0x8b/0x93 [<ffffffff8145b414>] kernel_thread_helper+0x4/0x10 [<ffffffff81044fe2>] ? __init_kthread_worker+0x39/0x39 [<ffffffff8145b410>] ? gs_change+0xb/0xb Code: 83 c4 10 49 83 3c 24 00 eb e4 48 83 fb 10 76 76 48 89 df e8 17 e1 ff ff 49 89 c1 48 8b 00 a8 80 75 15 49 f7 01 00 c0 00 00 75 02 <0f> 0b 4c 89 cf e8 b8 b4 fd ff eb 4f 4c 8b 55 08 49 8b 79 30 48 RIP [<ffffffff810cda19>] kfree+0x67/0xca RSP <ffff880134977d60> Signed-off-by: Ben Chan <benchan@chromium.org> Cc: Sage Ahn <syahn@gctsemi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-06-14USB: fix gathering of interface associationsDaniel Mack
TEAC's UD-H01 (and probably other devices) have a gap in the interface number allocation of their descriptors: Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 220 bNumInterfaces 3 [...] Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 [...] Interface Association: bLength 8 bDescriptorType 11 bFirstInterface 2 bInterfaceCount 2 bFunctionClass 1 Audio bFunctionSubClass 0 bFunctionProtocol 32 iFunction 4 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 2 bAlternateSetting 0 [...] Once a configuration is selected, usb_set_configuration() walks the known interfaces of a given configuration and calls find_iad() on each of them to set the interface association pointer the interface is included in. The problem here is that the loop variable is taken for the interface number in the comparison logic that gathers the association. Which is fine as long as the descriptors are sane. In the case above, however, the logic gets out of sync and the interface association fields of all interfaces beyond the interface number gap are wrong. Fix this by passing the interface's bInterfaceNumber to find_iad() instead.

2012-06-14usb: ehci-sh: fix illegal phy_init() running when platform_data is NULLShimoda, Yoshihiro

2012-06-14xen: mark local pages as FOREIGN in the m2p_overrideStefano Stabellini
When the frontend and the backend reside on the same domain, even if we add pages to the m2p_override, these pages will never be returned by mfn_to_pfn because the check "get_phys_to_machine(pfn) != mfn" will always fail, so the pfn of the frontend will be returned instead (resulting in a deadlock because the frontend pages are already locked).

A simplified call graph looks like this: pygrub QEMU ----------------------------------------------- do_read_cache_page io_submit | | lock_page ext3_direct_IO | bio_add_page | lock_page Internally the xen-blkback uses m2p_add_override to swizzle (temporarily) a 'struct page' to have a different MFN (so that it can point to another guest). It also can easily find out whether another pfn corresponding to the mfn exists in the m2p, and can set the FOREIGN bit in the p2m, making sure that mfn_to_pfn returns the pfn of the backend. This allows the backend to perform direct_IO on these pages, but as a side effect prevents the frontend from using get_user_pages_fast on them while they are being shared with the backend.

2012-06-14Btrfs: fix race in tree mod log additionJan Schmidt
When adding to the tree modification log, we grab two locks at different stages. We must not drop the outer lock until we're done with section protected by the inner lock. This moves the unlock call for the outer lock to the appropriate position. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
2012-06-14Btrfs: add btrfs_next_old_leafJan Schmidt
To make sense of the tree mod log, the backref walker not only needs btrfs_search_old_slot, but it also called btrfs_next_leaf, which in turn was calling btrfs_search_slot. This obviously didn't give the correct result. This commit adds btrfs_next_old_leaf, a drop-in replacement for btrfs_next_leaf with a time_seq parameter. If it is zero, it behaves exactly like btrfs_next_leaf. If it is non-zero, it will use btrfs_search_old_slot with this time_seq parameter. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
2012-06-14Btrfs: fix return value for __tree_mod_log_oldest_rootJan Schmidt
In __tree_mod_log_oldest_root() we must return the found operation even if it's not a ROOT_REPLACE operation. Otherwise, the caller assumes that there are no operations to be rewinded and returns immediately. The code in the caller is modified to improve readability.

2012-06-14Btrfs: use btrfs_read_lock_root_node in get_old_rootJan Schmidt
get_old_root could race with root node updates because we weren't locking the node early enough. Use btrfs_read_lock_root_node to grab the root locked in the very beginning and release the lock as soon as possible (just like btrfs_search_slot does). Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
2012-06-14Btrfs: remove obsolete btrfs_next_leaf call from __resolve_indirect_refJan Schmidt
When resolving indirect refs, we used to call btrfs_next_leaf in case we didn't find an exact match. While we should find exact matches most of the time, in case we don't, we must continue searching. Treating those matches differently depending on the level we're searching doesn't make sense. Even worse, we might end up searching for a key larger than the largest, in which case there is no next_leaf and subsequent jobs would fail. This commit drops the bogous lines.

2012-06-14Bluetooth: Fix sending HCI_Disconnect only when connectedVishal Agarwal
HCI_Disconnect should only be sent after connection is established. If connection is not yet established and HCI_Disconnect is called then disconnection complete will be received with a handle which does not exist and hence this event will be ignored. But as mgmt.c will not receive this event, its variable for pending command is not cleared.This will result in future Disconnect commands for that BD Address to be blocked with error busy.

2012-06-14ARM: 7422/1: mmc: mmci: Allocate platform memory during Device Tree bootLee Jones
When booting with Device Tree enabled, platform specific information is gathered by parsing the DT binary. Platform data is subsequently populated with the result. The memory required for this is not automatically allocated during Device Tree boot, so we'll do it here instead.

2012-06-14watchdog: Quiet down the boot messagesDon Zickus
A bunch of bugzillas have complained how noisy the nmi_watchdog is during boot-up especially with its expected failure cases (like virt and bios resource contention). This is my attempt to quiet them down and keep it less confusing for the end user. What I did is print the message for cpu0 and save it for future comparisons. If future cpus have an identical message as cpu0, then don't print the redundant info. However, if a future cpu has a different message, happily print that loudly. Before the change, you would see something like: ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 CPU0: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz stepping 0a Performance Events: PEBS fmt0+, Core2 events, Intel PMU driver. ... version: 2 ... bit width: 40 ... generic registers: 2 ... value mask: 000000ffffffffff ... max period: 000000007fffffff ... fixed-purpose events: 3 ... event mask: 0000000700000003 NMI watchdog enabled, takes one hw-pmu counter. Booting Node 0, Processors #1 NMI watchdog enabled, takes one hw-pmu counter. #2 NMI watchdog enabled, takes one hw-pmu counter. #3 Ok. NMI watchdog enabled, takes one hw-pmu counter. Brought up 4 CPUs Total of 4 processors activated (22607.24 BogoMIPS). After the change, it is simplified to: ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 CPU0: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz stepping 0a Performance Events: PEBS fmt0+, Core2 events, Intel PMU driver. ... version: 2 ... bit width: 40 ... generic registers: 2 ... value mask: 000000ffffffffff ... max period: 000000007fffffff ... fixed-purpose events: 3 ... event mask: 0000000700000003 NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.

2012-06-14DMA: PL330: Fix racy mutex unlockJavi Merino
pl330_update() stores a pointer to the thrd->req that finished, which contains a pointer to the corresponding pl330_req. This is done with the pl330_lock held. Then, it iterates through the req_done list, calling the callback for each of the requests that are done. The problem is that the driver releases the lock before calling the callback for each of the callbacks. pl330_submit_req() running in another processor can then acquire the lock and insert another request in one of the thrd->req that hasn't been processed yet, replacing the pointer to pl330_req there. When the callback returns in pl330_update() and the next rqdone is popped from the list, it dereferences the pl330_req pointer to the just scheduled pl330_req, instead of the one that has finished, calling pl330 with the wrong r. This patch fixes this by storing the pointer to pl330_req directly in the list.

2012-06-13Fix OMAP EHCI suspend/resume failure (i693)Anand Gadiyar
Its observed with some PHY, the 60Mhz clock gets cut too soon for OMAP EHCI, leaving OMAP-EHCI in a bad state. So on starting port suspend, make sure the 60Mhz clock to EHCI is kept alive using an internal clock, so that EHCi can cleanly transition its hw state machine on a port suspend. Its not proven if this is the issue hit on USB3333, but the symptoms look very similar.
