Debian toolcahin defaults to PIE, and I guess that will also be the case of most distributions.

Updates to the bitfields in struct packet_sock are not atomic. Serialize these read-modify-write cycles. Move po->running into a separate variable. Its writes are protected by po->bind_lock (except for one startup case at packet_create). Also replace a textual precondition warning with lockdep annotation.

2018-04-24drm/i915/breadcrumbs: Keep the fake irq armed across resetChris Wilson
Instead of synchronously cancelling the timer and re-enabling it inside the reset callbacks, keep the timer enabled and let it die on its next wakeup if no longer required. This allows intel_engine_reset_breadcrumbs() to be used from an atomic (timer/softirq) context such as required for resetting an engine. It also allows us to react better to the user poking around debugfs for testing missed irqs. v2: Tighten the order of del_timer_sync as the fake_irq timer may trigger the hangcheck timer, and so we should cancel it first and then cancel the hangcheck (Mika) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180424142945.6787-1-chris@chris-wilson.co.uk

2018-04-24igb: Fix the transmission mode of queue 0 for Qav modeVinicius Costa Gomes
When Qav mode is enabled, queue 0 should be kept on Stream Reservation mode. From the i210 datasheet, section 8.12.19: "Note: Queue0 QueueMode must be set to 1b when TransmitMode is set to Qav." ("QueueMode 1b" represents the Stream Reservation mode) The solution is to give queue 0 the all the credits it might need, so it has priority over queue 1. A situation where this can happen is when cbs is "installed" only on queue 1, leaving queue 0 alone. For example: $ tc qdisc replace dev enp2s0 handle 100: parent root mqprio num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 0 $ tc qdisc replace dev enp2s0 parent 100:2 cbs locredit -1470 \ hicredit 30 sendslope -980000 idleslope 20000 offload 1 Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2018-04-24ext4: fix bitmap position validationLukas Czerner
Currently in ext4_valid_block_bitmap() we expect the bitmap to be positioned anywhere between 0 and s_blocksize clusters, but that's wrong because the bitmap can be placed anywhere in the block group. This causes false positives when validating bitmaps on perfectly valid file system layouts. Fix it by checking whether the bitmap is within the group boundary.

2018-04-24drm/i915/fbdev: Enable late fbdev initial configurationJosé Roberto de Souza
If the initial fbdev configuration (intel_fbdev_initial_config()) runs and there still no sink connected it will cause drm_fb_helper_initial_config() to return 0 as no error happened (but internally the return is -EAGAIN). Because no framebuffer was allocated, when a sink is connected intel_fbdev_output_poll_changed() will not execute drm_fb_helper_hotplug_event() that would trigger another try to do the initial fbdev configuration. So here allowing drm_fb_helper_hotplug_event() to be executed when there is no framebuffer allocated and fbdev was not set up yet. This issue also happens when a MST DP sink is connected since boot, as the MST topology is discovered in parallel if intel_fbdev_initial_config() is executed before the first sink MST is discovered it will cause this same issue. This is a follow-up patch of https://patchwork.freedesktop.org/patch/196089/ Changes from v1: - not creating a dump framebuffer anymore, instead just allowing drm_fb_helper_hotplug_event() to execute when fbdev is not setup yet.

The Dell Dock USB-audio device with 0bda:4014 is behaving notoriously bad, and we have already applied some workaround to avoid the firmware hiccup. Yet we still need to skip one thing, the Extension Unit at ID 4, which doesn't react correctly to the mixer ctl access.

2018-04-24ACPI / button: make module loadable when booted in non-ACPI modeArd Biesheuvel
Modules such as nouveau.ko and i915.ko have a link time dependency on acpi_lid_open(), and due to its use of acpi_bus_register_driver(), the button.ko module that provides it is only loadable when booted in ACPI mode. However, the ACPI button driver can be built into the core kernel as well, in which case the dependency can always be satisfied, and the dependent modules can be loaded regardless of whether the system was booted in ACPI mode or not. So let's fix this asymmetry by making the ACPI button driver loadable as a module even if not booted in ACPI mode, so it can provide the acpi_lid_open() symbol in the same way as when built into the kernel.

2018-04-24ACPI / watchdog: Prefer iTCO_wdt on Lenovo Z50-70Mika Westerberg
WDAT table on Lenovo Z50-70 is using RTC SRAM (ports 0x70 and 0x71) to store state of the timer. This conflicts with Linux RTC driver (rtc-cmos.c) who fails to reserve those ports for itself preventing RTC from functioning. In addition the WDAT table seems not to be fully functional because it does not reset the system when the watchdog times out. On this system iTCO_wdt works just fine so we simply prefer to use it instead of WDAT. This makes RTC working again and also results working watchdog via iTCO_wdt.

2018-04-24libceph: reschedule a tick in finish_hunting()Ilya Dryomov
If we go without an established session for a while, backoff delay will climb to 30 seconds. The keepalive timeout is also 30 seconds, so it's pretty easily hit after a prolonged hunting for a monitor: we don't get a chance to send out a keepalive in time, which means we never get back a keepalive ack in time, cutting an established session and attempting to connect to a different monitor every 30 seconds: [Sun Apr 1 23:37:05 2018] libceph: mon0 10.80.20.99:6789 session established [Sun Apr 1 23:37:36 2018] libceph: mon0 10.80.20.99:6789 session lost, hunting for new mon [Sun Apr 1 23:37:36 2018] libceph: mon2 10.80.20.103:6789 session established [Sun Apr 1 23:38:07 2018] libceph: mon2 10.80.20.103:6789 session lost, hunting for new mon [Sun Apr 1 23:38:07 2018] libceph: mon1 10.80.20.100:6789 session established [Sun Apr 1 23:38:37 2018] libceph: mon1 10.80.20.100:6789 session lost, hunting for new mon [Sun Apr 1 23:38:37 2018] libceph: mon2 10.80.20.103:6789 session established [Sun Apr 1 23:39:08 2018] libceph: mon2 10.80.20.103:6789 session lost, hunting for new mon The regular keepalive interval is 10 seconds.
