2011-06-07USB: dummy-hcd needs the has_tt flagAlan Stern1-0/+1
Like with other host controllers capable of operating at both high speed and full speed, we need to indicate that the emulated controller presented by dummy-hcd has this ability. Otherwise usbcore will not accept full-speed gadgets under dummy-hcd. This patch (as1469) sets the appropriate has_tt flag.

2011-06-07usb-storage: redo incorrect readsAlan Stern6-2/+67
Some USB mass-storage devices have bugs that cause them not to handle the first READ(10) command they receive correctly. The Corsair Padlock v2 returns completely bogus data for its first read (possibly it returns the data in encrypted form even though the device is supposed to be unlocked). The Feiya SD/SDHC card reader fails to complete the first READ(10) command after it is plugged in or after a new card is inserted, returning a status code that indicates it thinks the command was invalid, which prevents the kernel from retrying the read. Since the first read of a new device or a new medium is for the partition sector, the kernel is unable to retrieve the device's partition table. Users have to manually issue an "hdparm -z" or "blockdev --rereadpt" command before they can access the device. This patch (as1470) works around the problem. It adds a new quirk flag, US_FL_INVALID_READ10, indicating that the first READ(10) should always be retried immediately, as should any failing READ(10) commands (provided the preceding READ(10) command succeeded, to avoid getting stuck in a loop). The patch also adds appropriate unusual_devs entries containing the new flag.

If user space attempts to remove a non-existent file or directory, and the file system is mounted read-only, return ENOENT instead of EROFS.

The main lock_is_held() user is lockdep_assert_held(), avoid false assertions in lockdep_off() sections by unconditionally reporting the lock is taken. [ the reason this is important is a lockdep_assert_held() in ttwu() which triggers a warning under lockdep_off() as in printk() which can trigger another wakeup and lock up due to spinlock recursion, as reported and heroically debugged by Arne Jansen ] Reported-and-tested-by: Arne Jansen <[email protected]> Signed-off-by: Peter Zijlstra <[email protected]> Cc: Linus Torvalds <[email protected]> Cc: <[email protected]> Link: http://lkml.kernel.org/r/1307398759.2497.966.camel@laptop Signed-off-by: Ingo Molnar <[email protected]>
2011-06-07x86/amd-iommu: Fix boot crash with hidden PCI devicesJoerg Roedel1-1/+21
Some PCIe cards ship with a PCI-PCIe bridge which is not visible as a PCI device in Linux. But the device-id of the bridge is present in the IOMMU tables which causes a boot crash in the IOMMU driver. This patch fixes by removing these cards from the IOMMU handling. This is a pure -stable fix, a real fix to handle this situation appriatly will follow for the next merge window. Cc: [email protected] # > 2.6.32 Signed-off-by: Joerg Roedel <[email protected]>
2011-06-07cifs: silence printk when establishing first session on socketJeff Layton1-1/+1
When signing is enabled, the first session that's established on a socket will cause a printk like this to pop: CIFS VFS: Unexpected SMB signature This is because the key exchange hasn't happened yet, so the signature field is bogus. Don't try to check the signature on the socket until the first session has been established. Also, eliminate the specific check for SMB_COM_NEGOTIATE since this check covers that case too.

The funtion option_send_status times out when sending USB messages to the interfaces 0, 1, and 2 of this UMTS stick. This results in a 5s timeout in the function causing other tty operations to feel very sluggish. This patch adds a blacklist entry for these 3 interfaces on the ZTE K3765-Z device.

This modem really wants sendsetup blacklisted for interfaces 0 and 1, otherwise the kernel hardlocks for about 10 seconds while waiting for the modem's firmware to respond, which it of course doesn't do. A slight complication here is that TCT (who owns the Alcatel brand) used the same USB IDs for the X200 as the X060s despite the devices having completely different firmware and AT command sets, so we end up adding the X060s to the blacklist at the same time.

By default the io_tlb_nslabs is set to zero, and gets set to whatever value is passed in via swiotlb_init_with_tbl function. The default value passed in is 64MB. However, if the user provides the 'swiotlb=<nslabs>' the default value is ignored and the value provided by the user is used... Except when the SWIOTLB is used under Xen - there the default value of 64MB is used and the Xen-SWIOTLB has no mechanism to get the 'io_tlb_nslabs' filled out by setup_io_tlb_npages functions.

2011-06-06[S390] kvm-s390: fix stfle facilities numbers >=64Christian Borntraeger1-0/+1
Currently KVM masks out the known good facilities only for the first double word, but passed the 2nd double word without filtering. This breaks some code on newer systems: [ 0.593966] ------------[ cut here ]------------ [ 0.594086] WARNING: at arch/s390/oprofile/hwsampler.c:696 [ 0.594213] Modules linked in: [ 0.594321] Modules linked in: [ 0.594439] CPU: 0 Not tainted 3.0.0-rc1 #46 [ 0.594564] Process swapper (pid: 1, task: 00000001effa8038, ksp: 00000001effafab8) [ 0.594735] Krnl PSW : 0704100180000000 00000000004ab89a (hwsampler_setup+0x75a/0x7b8) [ 0.594910] R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:0 CC:1 PM:0 EA:3 [ 0.595120] Krnl GPRS: ffffffff00000000 00000000ffffffea ffffffffffffffea 00000000004a98f8 [ 0.595351] 00000000004aa002 0000000000000001 000000000080e720 000000000088b9f8 [ 0.595522] 000000000080d3e8 0000000000000000 0000000000000000 000000000080e464 [ 0.595725] 0000000000000000 00000000005db198 00000000004ab3a2 00000001effafd98 [ 0.595901] Krnl Code: 00000000004ab88c: c0e5000673ca brasl %r14,57a020 [ 0.596071] 00000000004ab892: a7f4fc77 brc 15,4ab180 [ 0.596276] 00000000004ab896: a7f40001 brc 15,4ab898 [ 0.596454] >00000000004ab89a: a7c8ffa1 lhi %r12,-95 [ 0.596657] 00000000004ab89e: a7f4fc71 brc 15,4ab180 [ 0.596854] 00000000004ab8a2: a7f40001 brc 15,4ab8a4 [ 0.597029] 00000000004ab8a6: a7f4ff22 brc 15,4ab6ea [ 0.597230] 00000000004ab8aa: c0200011009a larl %r2,6cb9de [ 0.597441] Call Trace: [ 0.597511] ([<00000000004ab3a2>] hwsampler_setup+0x262/0x7b8) [ 0.597676] [<0000000000875812>] oprofile_arch_init+0x32/0xd0 [ 0.597834] [<0000000000875788>] oprofile_init+0x28/0x74 [ 0.597991] [<00000000001001be>] do_one_initcall+0x3a/0x170 [ 0.598151] [<000000000084fa22>] kernel_init+0x142/0x1ec [ 0.598314] [<000000000057db16>] kernel_thread_starter+0x6/0xc [ 0.598468] [<000000000057db10>] kernel_thread_starter+0x0/0xc [ 0.598606] Last Breaking-Event-Address: [ 0.598707] [<00000000004ab896>] hwsampler_setup+0x756/0x7b8 [ 0.598863] ---[ end trace ce3179037f4e3e5b ]--- So lets also mask the 2nd double word.

2011-06-06[S390] kvm-s390: Fix host crash on misbehaving guestsChristian Borntraeger1-0/+2
commit 9ff4cfb3fcfd48b49fdd9be7381b3be340853aa4 ([S390] kvm-390: Let kernel exit SIE instruction on work) fixed a problem of commit commit cd3b70f5d4d82f85d1e1d6e822f38ae098cf7c72 ([S390] virtualization aware cpu measurement) but uncovered another one. If a kvm guest accesses guest real memory that doesnt exist, the page fault handler calls the sie hook, which then rewrites the return psw from sie_inst to either sie_exit or sie_reenter. On return, the page fault handler will then detect the wrong access as a kernel fault causing a kernel oops in sie_reenter or sie_exit. We have to add these two addresses to the exception table to allow graceful exits. Signed-off-by: Christian Borntraeger <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>
2011-06-06video: Fix use-after-free by vga16fb on rmmodBruno Prémont1-0/+2
Since fb_info is now refcounted and thus may get freed at any time it gets unregistered module unloading will try to unregister framebuffer as stored in platform data on probe though this pointer may be stale. Cleanup platform data on framebuffer release. CC: [email protected] Signed-off-by: Bruno Prémont <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

Al Viro observes that in the hugetlb case, handle_mm_fault() may return a value of the kind ENOSPC when its caller is expecting a value of the kind VM_FAULT_SIGBUS: fix alloc_huge_page()'s failure returns.
