Rather than adding the two files individually, take the opportunity and add $(VMLINUX_OBJS) to "targets" instead, thus allowing the assignment at the top of the file to be shrunk quite a bit. At the same time, remove a pointless flags override line - the variable assigned to was misspelled anyway, and the options added are meaningless for assembly sources.

124dff0 Patrick McHardy 05 April 2013, 18:42:05 UTC netfilter: don't reset nf_trace in nf_reset() Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code to reset nf_trace in nf_reset(). This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

b2c87ca Bob Peterson 22 March 2013, 14:07:24 UTC GFS2: Issue discards in 512b sectors This patch changes GFS2's discard issuing code so that it calls function sb_issue_discard rather than blkdev_issue_discard. The code was calling blkdev_issue_discard and specifying the correct sector offset and sector size, but blkdev_issue_discard expects these values to be in terms of 512 byte sectors, even if the native sector size for the device is different. Calling sb_issue_discard with the BLOCK size instead ensures the correct block-to-512b-sector translation. I verified that "minlen" is specified in blocks, so comparing it to a number of blocks is correct.

19b0092 Mike Snitzer 05 April 2013, 14:36:34 UTC dm cache: reduce bio front_pad size in writeback mode A recent patch to fix the dm cache target's writethrough mode extended the bio's front_pad to include a 1056-byte struct dm_bio_details. Writeback mode doesn't need this, so this patch reduces the per_bio_data_size to 16 bytes in this case instead of 1096. The dm_bio_details structure was added in "dm cache: fix writes to cache device in writethrough mode" which fixed commit e2e74d617e ("dm cache: fix race in writethrough implementation"). In writeback mode we avoid allocating the writethrough-specific members of the per_bio_data structure (the dm_bio_details structure included).

b844fe6 Darrick J. Wong 05 April 2013, 14:36:32 UTC dm cache: fix writes to cache device in writethrough mode The dm-cache writethrough strategy introduced by commit e2e74d617eadc15 ("dm cache: fix race in writethrough implementation") issues a bio to the origin device, remaps and then issues the bio to the cache device. This more conservative in-series approach was selected to favor correctness over performance (of the previous parallel writethrough). However, this in-series implementation that reuses the same bio to write both the origin and cache device didn't take into account that the block layer's req_bio_endio() modifies a completing bio's bi_sector and bi_size. So the new writethrough strategy needs to preserve these bio fields, and restore them before submission to the cache device, otherwise nothing gets written to the cache (because bi_size is 0). This patch adds a struct dm_bio_details field to struct per_bio_data, and uses dm_bio_record() and dm_bio_restore() to ensure the bio is restored before reissuing to the cache device. Adding such a large structure to the per_bio_data is not ideal but we can improve this later, for now correctness is the important thing. This problem initially went unnoticed because the dm-cache test-suite uses a linear DM device for the dm-cache device's origin device. Writethrough worked as expected because DM submits a *clone* of the original bio, so the original bio which was reused for the cache was never touched. Signed-off-by: Darrick J.

80fa818 Ralf Baechle 25 March 2013, 12:43:14 UTC MIPS: Delete definition of SA_RESTORER. SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever supported its use and no libc was using it, so the entire sa-restorer functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.] for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid accidental reuse of the mask bit. Upstream cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear sa_restorer on execve] adds code that assumes sa_sigaction has an sa_restorer field, if SA_RESTORER is defined which would break MIPS.

0e82e7f Eric W. Biederman 03 April 2013, 16:14:47 UTC af_unix: If we don't care about credentials coallesce all messages It was reported that the following LSB test case failed https://lsbbugs.linuxfoundation.org/attachment.cgi?id=2144 because we were not coallescing unix stream messages when the application was expecting us to. The problem was that the first send was before the socket was accepted and thus sock->sk_socket was NULL in maybe_add_creds, and the second send after the socket was accepted had a non-NULL value for sk->socket and thus we could tell the credentials were not needed so we did not bother. The unnecessary credentials on the first message cause unix_stream_recvmsg to start verifying that all messages had the same credentials before coallescing and then the coallescing failed because the second message had no credentials. Ignoring credentials when we don't care in unix_stream_recvmsg fixes a long standing pessimization which would fail to coallesce messages when reading from a unix stream socket if the senders were different even if we did not care about their credentials. I have tested this and verified that the in the LSB test case mentioned above that the messages do coallesce now, while the were failing to coallesce without this change.

The problem that the above patch was meant to address is that af_unix messages are not being coallesced because we are sending unnecesarry credentials. Not sending credentials in maybe_add_creds totally breaks unconnected unix domain sockets that wish to send credentails to other sockets. In practice this break some versions of udev because they receive a message and the sending uid is bogus so they drop the message. Reported-by: Sven Joachim <svenjoac@gmx.de> Signed-off-by: "Eric W.

In bonding_exit() we first remove the devices (through rtnl_link_unregister() ) and only after that we remove the sysfs. If we manage to add a device through sysfs after that the devices were removed - we'll end up with that device/sysfs structure and with the module unloaded.

A few drivers use dev_uc_sync/unsync to synchronize the address lists from master down to slave/lower devices. In some cases (bond/team) a single address list is synched down to multiple devices. At the time of unsync, we have a leak in these lower devices, because "synced" is treated as a boolean and the address will not be unsynced for anything after the first device/call.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option override DCAPS] changed the behavior of power_save_controller so that it can override the driver capability. This assumed that this option is rarely changed dynamically unlike power_save option. Too naive. It turned out that the user-space power-management tool tries to set power_save_controller option to 1 together with power_save option without knowing what's actually doing. This enabled forcibly the runtime PM of the controller, which is known to be broken om many chips thus disabled as default. So, the only sane fix is to revert this commit again. It was intended to ease debugging/testing for runtime PM enablement, but obviously we need another way for it.

For this reason, avoid enabling runtime PM for PCIe ports by keeping their runtime PM reference counters always above 0 for the time being. When a PCIe port is suspended, it can no longer report events like hotplug, so hotplug below the port may not work, as in the bug report below.

24ad0ef Rafael J. Wysocki 28 March 2013, 11:07:29 UTC PCI/ACPI: Always resume devices on ACPI wakeup notifications It turns out that the _Lxx control methods provided by some BIOSes clear the PME Status bit of PCI devices they handle, which means that pci_acpi_wake_dev() cannot really use that bit to check whether or not the device has signalled wakeup. One symptom of the problem is, for example, that when an affected PCI USB controller is runtime-suspended, then plugging in a new USB device into one of the controller's ports will not wake up the controller, which should happen. For this reason, make pci_acpi_wake_dev() always attempt to resume the device it is called for regardless of the device's PME Status bit value (that bit still has to be cleared if set at this point, though).

This patch fixes the problem in a more elegant way by keeping a private ticks_per_jiffy field in the delay ops, independent of loops_per_jiffy and therefore not subject to scaling. The loop-based delay continues to use loops_per_jiffy directly, as it should.

Commit 6248d06 (ARM: 7545/1: cache-l2x0: make outer_cache_fns a field of l2x0_of_data) changed how .set_debug is initialized. Both commits break commit 74ddcdb (ARM: 7608/1: l2x0: Only set .set_debug on PL310 r3p0 and earlier) which uses the RTL version to conditionally set .set_debug function pointer. Commit b8db6b8 also caused the printed cache ID to be missing the version information. Fix this by reverting how the part number is masked so the RTL version info is maintained. The cache-id-part DT property does not set the RTL bits so masking them should have no effect. Also, re-arrange the order of the function pointer init so the .set_debug function can be overridden.

The same behavior is observed in other UAC2 hardware like the VIA VT1731. Reset the interface after setting the sampling frequency on sample rate changes, to ensure that the sample rate set by snd_usb_init_sample_rate() is used. Otherwise, the device will try to use the sample rate of the previous stream, causing distorted sound on sample rate changes. The reset is performed for all UAC2 devices, as it should not affect a standards compliant device, but it is only necessary for C-Media CM6631, VIA VT1731 and possibly others. Failure to read sample rate from the device is not handled as an error in set_sample_rate_v2(), as (permanent or intermittent) failure to read sample rate isn't essential for a successful sample rate set.

b8178f1 Bjorn Helgaas 01 April 2013, 21:47:39 UTC Revert "PCI/ACPI: Request _OSC control before scanning PCI root bus" This reverts commit 8c33f51df406e1a1f7fa4e9b244845b7ebd61fa6. Conflicts: drivers/acpi/pci_root.c This commit broke some pre-1.1 PCIe devices by leaving them with ASPM enabled. Previously, we had disabled ASPM on these devices because many of them don't implement it correctly (per 149e1637). Requesting _OSC control early means that aspm_disabled may be set before we scan the PCI bus and configure link ASPM state. But the ASPM configuration currently skips the check for pre-PCIe 1.1 devices when aspm_disabled is set, like this: acpi_pci_root_add acpi_pci_osc_support if (flags != base_flags) pcie_no_aspm aspm_disabled = 1 pci_acpi_scan_root ... pcie_aspm_init_link_state pcie_aspm_sanity_check if (!aspm_disabled) /* check for pre-PCIe 1.1 device */ Therefore, setting aspm_disabled early means that we leave ASPM enabled on these pre-PCIe 1.1 devices, which is a regression for some devices. The best fix would be to clean up the ASPM init so we can evaluate _OSC before scanning the bug (that way boot-time and hot-add discovery will work the same), but that requires significant rework. For now, we'll just revert the _OSC change as the lowest-risk fix. Reference: https://bugzilla.kernel.org/show_bug.cgi?id=55211 Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rafael J.

8b4b9f2 Paul Moore 15 February 2013, 17:21:43 UTC x86: remove the x32 syscall bitmask from syscall_get_nr() Commit fca460f95e928bae373daa8295877b6905bc62b8 simplified the x32 implementation by creating a syscall bitmask, equal to 0x40000000, that could be applied to x32 syscalls such that the masked syscall number would be the same as a x86_64 syscall. While that patch was a nice way to simplify the code, it went a bit too far by adding the mask to syscall_get_nr(); returning the masked syscall numbers can cause confusion with callers that expect syscall numbers matching the x32 ABI, e.g. unmasked syscall numbers. This patch fixes this by simply removing the mask from syscall_get_nr() while preserving the other changes from the original commit. While there are several syscall_get_nr() callers in the kernel, most simply check that the syscall number is greater than zero, in this case this patch will have no effect. Of those remaining callers, they appear to be few, seccomp and ftrace, and from my testing of seccomp without this patch the original commit definitely breaks things; the seccomp filter does not correctly filter the syscalls due to the difference in syscall numbers in the BPF filter and the value from syscall_get_nr(). Applying this patch restores the seccomp BPF filter functionality on x32. I've tested this patch with the seccomp BPF filters as well as ftrace and everything looks reasonable to me; needless to say general usage seemed fine as well.

After down-up, routes of other interface's IPv6 addresses through 'lo' are lost. IPv6 addresses assigned to all interfaces are routed through 'lo' for internal communication. Once 'lo' is down, those routing entries are removed from routing table. But those removed entries are not being re-created properly when 'lo' is brought up. So IPv6 addresses of other interfaces becomes unreachable from the same machine. Also this breaks communication with other machines because of NDISC packet processing failure. This patch fixes this issue by reading all interface's IPv6 addresses and adding them to IPv6 routing table while bringing up 'lo'. ==Testing== Before applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ After applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ Signed-off-by: Balakumaran Kannan <Balakumaran.Kannan@ap.sony.com> Signed-off-by: Maruthi Thotad <Maruthi.Thotad@ap.sony.com> Signed-off-by: David S.

A unique acpi_processor_cx is not sifficient by far. This patch is just a quick fix re-introducing the percpu cstates. If someone really wants to unify the ACPI cstates, please make sure that the whole software infrastructure is changed and take hardware as well as many different kinds of BIOS settings into account.

b34bb1e Rafael J. Wysocki 01 April 2013, 00:25:03 UTC ACPI / I2C: Use parent's ACPI_HANDLE() in acpi_i2c_register_devices() The ACPI handle of struct i2c_adapter's dev member should not be set, because this causes that struct i2c_adapter to be associated with the ACPI device node corresponding to its parent as the second "physical_device", which is incorrect (this happens during the registration of struct i2c_adapter). Consequently, acpi_i2c_register_devices() should use the ACPI handle of the parent of the struct i2c_adapter it is called for rather than the struct i2c_adapter's ACPI handle (which should be NULL). Make that happen and modify the i2c-designware-platdrv driver, which currently is the only driver for ACPI-enumerated I2C controller chips, not to set the ACPI handle for the struct i2c_adapter it creates.

'eld->monitor_present' should not be used here because 'eld' is a temp structure now and so its "monitor_present" is not set.

Otherwise it will be returned uninitialized as non-zero after ELD info is got successfully. Thus hdmi_present_sense() will always assume ELD info is invalid by mistake, and /proc file system cannot show the proper ELD info.
