2017-10-10device property: Track owner device of device propertyJarkko Nikula
Deletion of subdevice will remove device properties associated to parent when they share the same firmware node after commit 478573c93abd (driver core: Don't leak secondary fwnode on device removal). This was observed with a driver adding subdevice that driver wasn't able to read device properties after rmmod/modprobe cycle. Consider the lifecycle of it: parent device registration ACPI_COMPANION_SET() device_add_properties() pset_copy_set() set_secondary_fwnode(dev, &p->fwnode) device_add() parent probe read device properties ACPI_COMPANION_SET(subdevice, ACPI_COMPANION(parent)) device_add(subdevice) parent remove device_del(subdevice) device_remove_properties() set_secondary_fwnode(dev, NULL); pset_free() Parent device will have its primary firmware node pointing to an ACPI node and secondary firmware node point to device properties. ACPI_COMPANION_SET() call in parent probe will set the subdevice's firmware node to point to the same 'struct fwnode_handle' and the associated secondary firmware node, i.e. the device properties as the parent. When subdevice is deleted in parent remove that will remove those device properties and attempt to read device properties in next parent probe call will fail. Fix this by tracking the owner device of device properties and delete them only when owner device is being deleted.

2017-10-09cdc_ether: flag the u-blox TOBY-L2 and SARA-U2 as wwanAleksander Morgado
The u-blox TOBY-L2 is a LTE Cat 4 module with HSPA+ and 2G fallback. This module allows switching to different USB profiles with the 'AT+UUSBCONF' command, and provides a ECM network interface when the 'AT+UUSBCONF=2' profile is selected. The u-blox SARA-U2 is a HSPA module with 2G fallback. The default USB configuration includes a ECM network interface. Both these modules are controlled via AT commands through one of the TTYs exposed. Connecting these modules may be done just by activating the desired PDP context with 'AT+CGACT=1,<cid>' and then running DHCP on the ECM interface.

2017-10-09nbd: don't set the device size until we're connectedJosef Bacik
A user reported a regression with using the normal ioctl interface on newer kernels. This happens because I was setting the device size before the device was actually connected, which caused us to error out and close everything down. This didn't happen on netlink because we hold the device lock the whole time we're setting things up, but we don't do that for the ioctl path. This fixes the problem.

2017-10-09drm/i915: Read timings from the correct transcoder in intel_crtc_mode_get()Ville Syrjälä
intel_crtc->config->cpu_transcoder isn't yet filled out when intel_crtc_mode_get() gets called during output probing, so we should not use it there. Instead intel_crtc_mode_get() figures out the correct transcoder on its own, and that's what we should use. If the BIOS boots LVDS on pipe B, intel_crtc_mode_get() would actually end up reading the timings from pipe A instead (since PIPE_A==0), which clearly isn't what we want. It looks to me like this may have been broken by commit eccb140bca67 ("drm/i915: hw state readout&check support for cpu_transcoder") as that one removed the early initialization of cpu_transcoder from intel_crtc_init().

2017-10-09drm/i915/edp: Get the Panel Power Off timestamp after panel is offManasi Navare
Kernel stores the time in jiffies at which the eDP panel is turned off. This should be obtained after the panel is off (after the wait_panel_off). When we next attempt to turn the panel on, we use the difference between the timestamp at which we want to turn the panel on and timestamp at which panel was turned off to ensure that this is equal to panel power cycle delay and if not we wait for the remaining time. Not waiting for the panel power cycle delay can cause the panel to not turn on giving rise to AUX timeouts for the attempted AUX transactions. v2: * Separate lines for bugzilla (Jani Nikula) * Suggested by tag (Daniel Vetter) Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: stable@vger.kernel.org Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101518 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101144 Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Jani Nikula <jani.nikula@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1507135706-17147-1-git-send-email-manasi.d.navare@intel.com (cherry picked from commit cbacf02e7796fea02e5c6e46c90ed7cbe9e6f2c0) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2017-10-08mlxsw: spectrum_router: Avoid expensive lookup during route removalIdo Schimmel
In commit fc922bb0dd94 ("mlxsw: spectrum_router: Use one LPM tree for all virtual routers") I increased the scale of supported VRFs by having all of them share the same LPM tree. In order to avoid look-ups for prefix lengths that don't exist, each route removal would trigger an aggregation across all the active virtual routers to see which prefix lengths are in use and which aren't and structure the tree accordingly. With the way the data structures are currently laid out, this is a very expensive operation. When preformed repeatedly - due to the invocation of the abort mechanism - and with enough VRFs, this can result in a hung task. For now, avoid this optimization until it can be properly re-added in net-next.

2017-10-08pinctrl: cherryview: fix issues caused by dynamic gpio irqs mappingGrygorii Strashko
New GPIO IRQs are allocated and mapped dynamically by default when GPIO IRQ infrastructure is used by cherryview-pinctrl driver. This causes issues on some Intel platforms [1][2] with broken BIOS which hardcodes Linux IRQ numbers in their ACPI tables. On such platforms cherryview-pinctrl driver should allocate and map all GPIO IRQs at probe time. Side effect - "Cannot allocate irq_descs @ IRQ%d, assuming pre-allocated\n" can be seen at boot log. NOTE. It still may fail if boot sequence will changed and some interrupt controller will be probed before cherryview-pinctrl which will shift Linux IRQ numbering (expected with CONFIG_SPARCE_IRQ enabled).

Now acking of edge irqs happens the following way: - omap_gpio_irq_handler - "isr" = read irq status - omap_clear_gpio_irqbank(bank, isr_saved & ~level_mask); ^ clear edge status, so irq can be accepted - loop while "isr" generic_handle_irq() - handle_edge_irq() - desc->irq_data.chip->irq_ack(&desc->irq_data); - omap_gpio_ack_irq() it might be that at this moment edge IRQ was triggered again and it will be cleared and IRQ will be lost. Use handle_simple_irq and clear edge interrupts early without disabling them in omap_gpio_irq_handler to avoid loosing interrupts.

2017-10-07crypto: stm32 - Try to fix hash paddingArnd Bergmann
gcc warns that the length for the extra unaligned data in the hash function may be used unaligned. In theory this could happen if we pass a zero-length sg_list, or if sg_is_last() was never true: In file included from drivers/crypto/stm32/stm32-hash.c:23: drivers/crypto/stm32/stm32-hash.c: In function 'stm32_hash_one_request': include/uapi/linux/kernel.h:12:49: error: 'ncp' may be used uninitialized in this function [-Werror=maybe-uninitialized] #define __KERNEL_DIV_ROUND_UP(n, d) (((n) + (d) - 1) / (d)) Neither of these can happen in practice, so the warning is harmless. However while trying to suppress the warning, I noticed multiple problems with that code: - On big-endian kernels, we byte-swap the data like we do for register accesses, however this is a data stream and almost certainly needs to use a single writesl() instead of series of writel() to give the correct hash. - If the length is not a multiple of four bytes, we skip the last word entirely, since we write the truncated length using stm32_hash_set_nblw(). - If we change the code to round the length up rather than down, the last bytes contain stale data, so it needs some form of padding. This tries to address all four problems, by correctly initializing the length to zero, using endian-safe copy functions, adding zero-padding and passing the padded length. I have done no testing on this patch, so please review carefully and if possible test with an unaligned length and big-endian kernel builds.

2017-10-06ppp: fix race in ppp device destructionGuillaume Nault
ppp_release() tries to ensure that netdevices are unregistered before decrementing the unit refcount and running ppp_destroy_interface(). This is all fine as long as the the device is unregistered by ppp_release(): the unregister_netdevice() call, followed by rtnl_unlock(), guarantee that the unregistration process completes before rtnl_unlock() returns. However, the device may be unregistered by other means (like ppp_nl_dellink()). If this happens right before ppp_release() calling rtnl_lock(), then ppp_release() has to wait for the concurrent unregistration code to release the lock. But rtnl_unlock() releases the lock before completing the device unregistration process. This allows ppp_release() to proceed and eventually call ppp_destroy_interface() before the unregistration process completes. Calling free_netdev() on this partially unregistered device will BUG(): ------------[ cut here ]------------ kernel BUG at net/core/dev.c:8141! invalid opcode: 0000 [#1] SMP CPU: 1 PID: 1557 Comm: pppd Not tainted 4.14.0-rc2+ #4 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1.fc26 04/01/2014 Call Trace: ppp_destroy_interface+0xd8/0xe0 [ppp_generic] ppp_disconnect_channel+0xda/0x110 [ppp_generic] ppp_unregister_channel+0x5e/0x110 [ppp_generic] pppox_unbind_sock+0x23/0x30 [pppox] pppoe_connect+0x130/0x440 [pppoe] SYSC_connect+0x98/0x110 ? do_fcntl+0x2c0/0x5d0 SyS_connect+0xe/0x10 entry_SYSCALL_64_fastpath+0x1a/0xa5 RIP: free_netdev+0x107/0x110 RSP: ffffc28a40573d88 ---[ end trace ed294ff0cc40eeff ]--- We could set the ->needs_free_netdev flag on PPP devices and move the ppp_destroy_interface() logic in the ->priv_destructor() callback.

2017-10-05dm raid: fix incorrect status output at the end of a "recover" processJonathan Brassow
There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress().
