2019-11-02HID: i2c-hid: Send power-on command after resetHans de Goede1-0/+4
Before commit 67b18dfb8cfc ("HID: i2c-hid: Remove runtime power management"), any i2c-hid touchscreens would typically be runtime-suspended between the driver loading and Xorg or a Wayland compositor opening it, causing it to be resumed again. This means that before this change, we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the graphical session would start listening to the touchscreen. It turns out that at least some SIS touchscreens, such as the one found on the Asus T100HA, need a power-on command after reset, otherwise they will not send any events.

As reported in [0] at least one RTL8168dp version has problems establishing a link. This chip version has an integrated RTL8211b PHY, however the chip seems to report a wrong PHY ID, resulting in a wrong PHY driver (for Generic Realtek PHY) being loaded. Work around this issue by adding a hook to r8168dp_2_mdio_read() for returning the correct PHY ID.

2019-11-01net: dsa: bcm_sf2: Fix IMP setup for port different than 8Florian Fainelli1-15/+21
Since it became possible for the DSA core to use a CPU port different than 8, our bcm_sf2_imp_setup() function was broken because it assumes that registers are applicable to port 8. In particular, the port's MAC is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS bits if we are not configured for port 8.

2019-11-01inet: stop leaking jiffies on the wireEric Dumazet1-1/+1
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-11-01 This series contains updates to e1000, igb, igc, ixgbe, i40e and driver documentation. Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation. Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear it twice. v2: Fixed alignment issue in patch 3 of the series based on community feedback. ==================== Signed-off-by: David S.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier1-1/+2
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.

An interesting observation made with our parallel selftests was that on our small/single cpu systems we would call kthread_stop() before the kthreads were spawned. If this happens, the kthread is never run at all; completely bypassing the test. A simple yield() from the parent will ensure that all children have the opportunity to start before we reap them.

Currently configurations can be generated where IOMMU_SUPPORT is disabled but IOMMU_IOVA is built as a module and DRM_TEGRA as built-in. In such a case, the symbols guarded by IOMMU_IOVA will not be available when linking the Tegra DRM driver and cause a linking failure. Simplify this by unconditionally selecting IOMMU_IOVA, which makes sure that it will be forced to =y if DRM_TEGRA=y. Technically we can now get IOMMU_IOVA code built-in even if we don't use it (Tegra DRM only uses it when IOMMU_SUPPORT is also enabled), but such configuration are of a mostly academic nature.

Don't just look at the very last request in a queue when deciding if we need to evict the context from the GPU, as that request may still be in the submission queue while the rest of the context is running! Instead, walk back along the queued requests looking for the active request and checking that.

2019-10-31igb/igc: Don't warn on fatal read failures when the device is removedLyude Paul2-2/+4
Fatal read errors are worth warning about, unless of course the device was just unplugged from the machine - something that's a rather normal occurrence when the igb/igc adapter is located on a Thunderbolt dock. So, let's only WARN() if there's a fatal read error while the device is still present. This fixes the following WARN splat that's been appearing whenever I unplug my Caldigit TS3 Thunderbolt dock from my laptop: igb 0000:09:00.0 enp9s0: PCIe link lost ------------[ cut here ]------------ igb: Failed to read reg 0x18!

2019-10-31drm/i915/lmem: add the fake lmem regionMatthew Auld9-0/+140
Intended for upstream testing so that we can still exercise the LMEM plumbing and !i915_ggtt_has_aperture paths. Smoke tested on Skull Canyon device. This works by allocating an intel_memory_region for a reserved portion of system memory, which we treat like LMEM. For the LMEMBAR we steal the aperture and 1:1 it map to the stolen region. To enable simply set the i915 modparam fake_lmem_start= on the kernel cmdline with the start of reserved region(see memmap=). The size of the region we can use is determined by the size of the mappable aperture, so the size of reserved region should be >= mappable_end. For now we only enable for the selftests. Depends on CONFIG_DRM_I915_UNSTABLE being enabled. eg. memmap=2G$16G i915.fake_lmem_start=0x400000000 v2: make fake_lmem_start an i915 modparam Signed-off-by: Matthew Auld <[email protected]> Cc: Joonas Lahtinen <[email protected]> Cc: Abdiel Janulgue <[email protected]> Cc: Arkadiusz Hiler <[email protected]> Cc: Chris Wilson <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Signed-off-by: Chris Wilson <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2019-10-31netdevsim: Fix use-after-free during device dismantleIdo Schimmel1-0/+5
Commit da58f90f11f5 ("netdevsim: Add devlink-trap support") added delayed work to netdevsim that periodically iterates over the registered netdevsim ports and reports various packet traps via devlink. While the delayed work takes the 'port_list_lock' mutex to protect against concurrent addition / deletion of ports, during device creation / dismantle ports are added / deleted without this lock, which can result in a use-after-free [1]. Fix this by making sure that the ports list is always modified under the lock.

2019-10-31drm/i915: Split detaching and removing the vmaChris Wilson1-20/+17
In order to keep the assert_bind_count() valid, we need to hold the vma page reference until after we drop the bind count. However, we must also keep the drm_mm_remove_node() as the last action of i915_vma_unbind() so that it serialises with the unlocked check inside i915_vma_destroy(). So we need to split up i915_vma_remove() so that we order the detach, drop pages and remove as required during unbind.
