2009-02-06ACPICA: Allow multiple backslash prefix in namepathsLin Ming
commit d037c5fd7367548191eab2b376a1d08c4ffaf7ff upstream. In a fully qualified namepath, allow multiple backslash prefixes. This can happen because of the use of a double-backslash in strings (since backslash is the escape character) causing confusion.

2009-02-06sata_mv: Fix chip type for Hightpoint RocketRaid 1740/1742Mark Lord
commit 4462254ac6be9150aae87d54d388fc348d6fcead upstream. Fix chip type for the Highpoint RocketRAID 1740 and 1742 PCI cards. These really do have Marvell 6042 chips on them, rather than the 5081 chip. Confirmed by multiple (two) users (for the 1740), and by examining the product photographs from Highpoint's web site.

2009-02-06dlm: initialize file_lock struct in GETLK before copying conflicting lockJeff Layton
commit 20d5a39929232a715f29e6cb7e3f0d0c790f41eb upstream. dlm_posix_get fills out the relevant fields in the file_lock before returning when there is a lock conflict, but doesn't clean out any of the other fields in the file_lock. When nfsd does a NFSv4 lockt call, it sets the fl_lmops to nfsd_posix_mng_ops before calling the lower fs. When the lock comes back after testing a lock on GFS2, it still has that field set. This confuses nfsd into thinking that the file_lock is a nfsd4 lock. Fix this by making DLM reinitialize the file_lock before copying the fields from the conflicting lock.

2009-02-06ACPI: Do not modify SCI_EN directlyRafael J. Wysocki
commit 11e93130c7ce5228d484fd5e86f3984835d4256b upstream. According to the ACPI specification the SCI_EN flag is controlled by the hardware, which sets this flag to inform the kernel that ACPI is enabled. For this reason, we shouldn't try to modify SCI_EN directly. Also, we don't need to do it in irqrouter_resume(), since lower-level resume code takes care of enabling ACPI in case it hasn't been enabled by the BIOS before passing control to the kernel (which by the way is against the ACPI specification).

2009-02-06x86: fix page attribute corruption with cpa()Suresh Siddha
commit a1e46212a410793d575718818e81ddc442a65283 upstream. Impact: fix sporadic slowdowns and warning messages This patch fixes a performance issue reported by Linus on his Nehalem system. While Linus reverted the PAT patch (commit 58dab916dfb57328d50deb0aa9b3fc92efa248ff) which exposed the issue, existing cpa() code can potentially still cause wrong(page attribute corruption) behavior. This patch also fixes the "WARNING: at arch/x86/mm/pageattr.c:560" that various people reported. In 64bit kernel, kernel identity mapping might have holes depending on the available memory and how e820 reports the address range covering the RAM, ACPI, PCI reserved regions. If there is a 2MB/1GB hole in the address range that is not listed by e820 entries, kernel identity mapping will have a corresponding hole in its 1-1 identity mapping. If cpa() happens on the kernel identity mapping which falls into these holes, existing code fails like this: __change_page_attr_set_clr() __change_page_attr() returns 0 because of if (!kpte). But doesn't set cpa->numpages and cpa->pfn. cpa_process_alias() uses uninitialized cpa->pfn (random value) which can potentially lead to changing the page attribute of kernel text/data, kernel identity mapping of RAM pages etc. oops! This bug was easily exposed by another PAT patch which was doing cpa() more often on kernel identity mapping holes (physical range between max_low_pfn_mapped and 4GB), where in here it was setting the cache disable attribute(PCD) for kernel identity mappings aswell. Fix cpa() to handle the kernel identity mapping holes.

2009-02-06nfsd: only set file_lock.fl_lmops in nfsd4_lockt if a stateowner is foundJeff Layton
commit fa82a491275a613b15489aab4b99acecb00958d3 upstream. nfsd4_lockt does a search for a lockstateowner when building the lock struct to test. If one is found, it'll set fl_owner to it. Regardless of whether that happens, it'll also set fl_lmops. Given that this lock is basically a "lightweight" lock that's just used for checking conflicts, setting fl_lmops is probably not appropriate for it. This behavior exposed a bug in DLM's GETLK implementation where it wasn't clearing out the fields in the file_lock before filling in conflicting lock info. While we were able to fix this in DLM, it still seems pointless and dangerous to set the fl_lmops this way when we may have a NULL lockstateowner.

2009-02-06nfsd: Ensure nfsv4 calls the underlying filesystem on LOCKTJ. Bruce Fields
commit 55ef1274dddd4de387c54d110e354ffbb6cdc706 upstream. Since nfsv4 allows LOCKT without an open, but the ->lock() method is a file method, we fake up a struct file in the nfsv4 code with just the fields we need initialized. But we forgot to initialize the file operations, with the result that LOCKT never results in a call to the filesystem's ->lock() method (if it exists). We could just add that one more initialization. But this hack of faking up a struct file with only some fields initialized seems the kind of thing that might cause more problems in the future. We should either do an open and get a real struct file, or make lock-testing an inode (not a file) method. This patch does the former.

commit 878b8619f711280fd05845e21956434b5e588cc4 upstream. Fix an off-by-two memory error in console selection. The loop below goes from sel_start to sel_end (inclusive), so it writes one more character. This one more character was added to the allocated size (+1), but it was not multiplied by an UTF-8 multiplier. This patch fixes a memory corruption when UTF-8 console is used and the user selects a few characters, all of them 3-byte in UTF-8 (for example a frame line). When memory redzones are enabled, a redzone corruption is reported. When they are not enabled, trashing of random memory occurs.

2009-02-06fbdev/atyfb: Fix DSP config on some PowerMacs & PowerBooksRisto Suominen
commit 7fbb7cadd062baf299fd8b26a80ea99da0c3fe01 upstream. Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500 and PowerMac G3 Beige rev A) with ATI Mach64 chip have suffered from unstable columns in their framebuffer image. This seems to depend on a value (4) read from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to be written to the chip. This patch uses a value calculated by aty_init_pll_ct instead, as a starting point. There are questions as to whether this should be extended to other platforms or maybe made dependent on specific chip types, but in the meantime, this has been tested on various powermacs and works for them so let's commit it.

2009-02-06x86: use early clobbers in usercopy*.cAndi Kleen
commit e0a96129db574d6365e3439d16d88517c437ab33 upstream. Impact: fix rare (but currently harmless) miscompile with certain configs and gcc versions Hugh Dickins noticed that strncpy_from_user() was miscompiled in some circumstances with gcc 4.3. Thanks to Hugh's excellent analysis it was easy to track down. Hugh writes: > Try building an x86_64 defconfig 2.6.29-rc1 kernel tree, > except not quite defconfig, switch CONFIG_PREEMPT_NONE=y > and CONFIG_PREEMPT_VOLUNTARY off (because it expands a > might_fault() there, which hides the issue): using a > gcc 4.3.2 (I've checked both openSUSE 11.1 and Fedora 10). > > It generates the following: > > 0000000000000000 <__strncpy_from_user>: > 0: 48 89 d1 mov %rdx,%rcx > 3: 48 85 c9 test %rcx,%rcx > 6: 74 0e je 16 <__strncpy_from_user+0x16> > 8: ac lods %ds:(%rsi),%al > 9: aa stos %al,%es:(%rdi) > a: 84 c0 test %al,%al > c: 74 05 je 13 <__strncpy_from_user+0x13> > e: 48 ff c9 dec %rcx > 11: 75 f5 jne 8 <__strncpy_from_user+0x8> > 13: 48 29 c9 sub %rcx,%rcx > 16: 48 89 c8 mov %rcx,%rax > 19: c3 retq > > Observe that "sub %rcx,%rcx; mov %rcx,%rax", whereas gcc 4.2.1 > (and many other configs) say "sub %rcx,%rdx; mov %rdx,%rax". > Isn't it returning 0 when it ought to be returning strlen? The asm constraints for the strncpy_from_user() result were missing an early clobber, which tells gcc that the last output arguments are written before all input arguments are read. Also add more early clobbers in the rest of the file and fix 32-bit usercopy.c in the same way. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com> [ since this API is rarely used and no in-kernel user relies on a 'len' return value (they only rely on negative return values) this miscompile was never noticed in the field.

commit 23e55a32ca1ffdbe7a492ef99f0e0ac48e504a13 upstream. It was pointed out by Breno Leitao <leitao@linux.vnet.ibm.com> that ixgb would crash on PPC when an IOMMU was in use, if change_mtu was called. It appears to be a pretty simple issue in the driver that wasn't discovered because most systems don't run with an IOMMU. The driver needs to only unmap buffers that are mapped (duh).

commit eb83bbf57429ab80f49b413e3e44d3b19c3fdc5a upstream. After reports of poor performance, a review of the latest vendor driver (rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken. A difference was found in the code used to index the OFDM power tables. When the Linux driver was changed, my unit works at a much greater range than before. I think this fixes Bugzilla #12380 and has been tested by at least two other users.

2009-02-02sound: virtuoso: do not overwrite EEPROM on Xonar D2/D2XClemens Ladisch
commit 7e86c0e6850504ec9516b953f316a47277825e33 upstream. On the Asus Xonar D2 and D2X models, the SPI chip select signal for the fourth DAC shares its pin with the serial clock for the EEPROM that contains the PCI subdevice ID values. It appears that when DAC registers are written and some other unknown conditions occur (probably noise on the EEPROM's chip select line), the EEPROM gets overwritten with garbage, which makes it impossible to properly detect the card later. Therefore, we better avoid DAC register writes and make sure that the driver works with the DAC's registers' default values. Consequently, the sample format is now I2S instead of left-justified (no user-visible change), and the DAC's volume/mute registers cannot be used anymore (volume changes are now done by the software volume plugin).

commit a229fc61ef0ee3c30fd193beee0eeb87410227f1 upstream. bsg.h in current form is perfectly suitable for user-mode consumption. It is needed together with scsi/sg.h for applications that want to interface with the bsg driver. Currently the few projects that use it would copy it over into the projects. But that is not acceptable for projects that need to provide source and devel packages for distros. This should also be submitted to stable 2.6.28 and 2.6.27 since bsg had a stable API since these Kernels and distro users will need the header for these kernels a swell Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Acked-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
