2022-06-29net: bonding: fix use-after-free after 802.3ad slave unbindYevhen Orlov1-1/+2
commit 0622cab0341c ("bonding: fix 802.3ad aggregator reselection"), resolve case, when there is several aggregation groups in the same bond. bond_3ad_unbind_slave will invalidate (clear) aggregator when __agg_active_ports return zero. So, ad_clear_agg can be executed even, when num_of_ports!=0. Than bond_3ad_unbind_slave can be executed again for, previously cleared aggregator. NOTE: at this time bond_3ad_unbind_slave will not update slave ports list, because lag_ports==NULL. So, here we got slave ports, pointing to freed aggregator memory. Fix with checking actual number of ports in group (as was before commit 0622cab0341c ("bonding: fix 802.3ad aggregator reselection") ), before ad_clear_agg().

2022-06-29net: phy: Don't trigger state machine while in suspendLukas Wunner2-0/+46
Upon system sleep, mdio_bus_phy_suspend() stops the phy_state_machine(), but subsequent interrupts may retrigger it: They may have been left enabled to facilitate wakeup and are not quiesced until the ->suspend_noirq() phase. Unwanted interrupts may hence occur between mdio_bus_phy_suspend() and dpm_suspend_noirq(), as well as between dpm_resume_noirq() and mdio_bus_phy_resume(). Retriggering the phy_state_machine() through an interrupt is not only undesirable for the reason given in mdio_bus_phy_suspend() (freezing it midway with phydev->lock held), but also because the PHY may be inaccessible after it's suspended: Accesses to USB-attached PHYs are blocked once usb_suspend_both() clears the can_submit flag and PHYs on PCI network cards may become inaccessible upon suspend as well. Amend phy_interrupt() to avoid triggering the state machine if the PHY is suspended. Signal wakeup instead if the attached net_device or its parent has been configured as a wakeup source. (Those conditions are identical to mdio_bus_phy_may_suspend().) Postpone handling of the interrupt until the PHY has resumed. Before stopping the phy_state_machine() in mdio_bus_phy_suspend(), wait for a concurrent phy_interrupt() to run to completion. That is necessary because phy_interrupt() may have checked the PHY's suspend status before the system sleep transition commenced and it may thus retrigger the state machine after it was stopped. Likewise, after re-enabling interrupt handling in mdio_bus_phy_resume(), wait for a concurrent phy_interrupt() to complete to ensure that interrupts which it postponed are properly rerun. The issue was exposed by commit 1ce8b37241ed ("usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling"), but has existed since forever.

2022-06-29Input: i8042 - add TUXEDO devices to i8042 quirk tablesWerner Sembach1-0/+129
A lot of modern Clevo barebones have touchpad and/or keyboard issues after suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use. No negative effects could be observed when setting all four. The list is quite massive as neither the TUXEDO nor the Clevo dmi strings have been very consistent historically. I tried to keep the list as short as possible without risking on missing an affected device. This is revision 3. The Clevo N150CU barebone is still removed as it might have problems with the fix and needs further investigations. The SchenkerTechnologiesGmbH System-/Board-Vendor string variations are added. This is now based in the quirk table refactor. This now also includes the additional noaux flag for the NS7xMU.

2022-06-29Input: i8042 - merge quirk tablesWerner Sembach1-500/+590
Merge i8042 quirk tables to reduce code duplication for devices that need more than one quirk. Before every quirk had its own table with devices needing that quirk. If a new quirk needed to be added a new table had to be created. When a device needed multiple quirks, it appeared in multiple tables. Now only one table called i8042_dmi_quirk_table exists. In it every device has one entry and required quirks are coded in the .driver_data field of the struct dmi_system_id used by this table. Multiple quirks for one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines. Also align quirkable options with command line parameters and make vendor wide quirks per device overwriteable on a per device basis. The first match is honored while following matches are ignored. So when a vendor wide quirk is defined in the table, a device can inserted before and therefore ignoring the vendor wide define.

2022-06-29drm/i915/guc/slpc: Add a new SLPC selftestVinay Belgaumkar1-167/+154
This test will validate we can achieve actual frequency of RP0. Pcode grants frequencies based on what GuC is requesting. However, thermal throttling can limit what is being granted. Add a test to request for max, but don't fail the test if RP0 is not granted due to throttle reasons. Also optimize the selftest by using a common run_test function to avoid code duplication. Rename the "clamp" tests to vary_max_freq and vary_min_freq. v2: Fix compile warning v3: Review comments (Ashutosh).

2022-06-30PM / devfreq: Rework freq_table to be local to devfreq structChristian Marangi2-44/+41
On a devfreq PROBE_DEFER, the freq_table in the driver profile struct, is never reset and may be leaved in an undefined state. This comes from the fact that we store the freq_table in the driver profile struct that is commonly defined as static and not reset on PROBE_DEFER. We currently skip the reinit of the freq_table if we found it's already defined since a driver may declare his own freq_table. This logic is flawed in the case devfreq core generate a freq_table, set it in the profile struct and then PROBE_DEFER, freeing the freq_table. In this case devfreq will found a NOT NULL freq_table that has been freed, skip the freq_table generation and probe the driver based on the wrong table. To fix this and correctly handle PROBE_DEFER, use a local freq_table and max_state in the devfreq struct and never modify the freq_table present in the profile struct if it does provide it.

2022-06-30PM / devfreq: Fix cpufreq passive unregister erroring on PROBE_DEFERChristian 'Ansuel' Marangi1-22/+17
With the passive governor, the cpu based scaling can PROBE_DEFER due to the fact that CPU policy are not ready. The cpufreq passive unregister notifier is called both from the GOV_START errors and for the GOV_STOP and assume the notifier is successfully registred every time. With GOV_START failing it's wrong to loop over each possible CPU since the register path has failed for some CPU policy not ready. Change the logic and unregister the notifer based on the current allocated parent_cpu_data list to correctly handle errors and the governor unregister path.
