2023-09-14power: supply: rk817: Add missing module aliasNicolas Frattaroli
Similar to the rk817 codec alias that was missing, the rk817 charger driver is missing a module alias as well. This absence prevents the driver from autoprobing on OF systems when it is built as a module. Add the right MODULE_ALIAS to fix this.

2023-09-14dm: fix a race condition in retrieve_depsMikulas Patocka
There's a race condition in the multipath target when retrieve_deps races with multipath_message calling dm_get_device and dm_put_device. retrieve_deps walks the list of open devices without holding any lock but multipath may add or remove devices to the list while it is running. The end result may be memory corruption or use-after-free memory access. See this description of a UAF with multipath_message(): https://listman.redhat.com/archives/dm-devel/2022-October/052373.html Fix this bug by introducing a new rw semaphore "devices_lock". We grab devices_lock for read in retrieve_deps and we grab it for write in dm_get_device and dm_put_device.

2023-09-13scsi: lpfc: Prevent use-after-free during rmmod with mapped NVMe rportsJustin Tee
During rmmod, when dev_loss_tmo callback is called, an ndlp kref count is decremented twice. Once for SCSI transport registration and second to remove the initial node allocation kref. If there is also an NVMe transport registration, another reference count decrement is expected in lpfc_nvme_unregister_port(). Race conditions between the NVMe transport remoteport_delete and dev_loss_tmo callbacks sometimes results in premature ndlp object release resulting in use-after-free issues. Fix by not dropping the ndlp object in dev_loss_tmo callback with an outstanding NVMe transport registration. Inversely, mark the final NLP_DROPPED flag in lpfc_nvme_unregister_port when rmmod flag is set.

2023-09-13scsi: lpfc: Early return after marking final NLP_DROPPED flag in dev_loss_tmoJustin Tee
When a dev_loss_tmo event occurs, an ndlp lock is taken before checking nlp_flag for NLP_DROPPED. There is an attempt to restore the ndlp lock when exiting the if statement, but the nlp_put kref could be the final decrement causing a use-after-free memory access on a released ndlp object. Instead of trying to reacquire the ndlp lock after checking nlp_flag, just return after calling nlp_put.

Change the logging of each algorithm from info level to debug level. On the original devices supported by this code there were typically only one or two algorithms in a firmware and one or two DSPs so this logging only used a small number of log lines. However, for the latest devices there could be 30-40 algorithms in a firmware and 8 DSPs being loaded in parallel, so using 300+ lines of log for information that isn't particularly important to have logged.

So the cleanup didn't take place, and the incorrect VF setup in the igb_adapter structure fooled the igb driver into assuming that VFs have been set up where no VF actually existed. Fix this problem by cleaning up again if pci_enable_sriov() fails.

2023-09-13ixgbe: fix timestamp configuration codeVadim Fedorenko
The commit in fixes introduced flags to control the status of hardware configuration while processing packets. At the same time another structure is used to provide configuration of timestamper to user-space applications. The way it was coded makes this structures go out of sync easily. The repro is easy for 82599 chips: [root@hostname ~]# hwstamp_ctl -i eth0 -r 12 -t 1 current settings: tx_type 0 rx_filter 0 new settings: tx_type 1 rx_filter 12 The eth0 device is properly configured to timestamp any PTPv2 events. [root@hostname ~]# hwstamp_ctl -i eth0 -r 1 -t 1 current settings: tx_type 1 rx_filter 12 SIOCSHWTSTAMP failed: Numerical result out of range The requested time stamping mode is not supported by the hardware. The error is properly returned because HW doesn't support all packets timestamping. But the adapter->flags is cleared of timestamp flags even though no HW configuration was done. From that point no RX timestamps are received by user-space application. But configuration shows good values: [root@hostname ~]# hwstamp_ctl -i eth0 current settings: tx_type 1 rx_filter 12 Fix the issue by applying new flags only when the HW was actually configured.

2023-09-13pmdomain: Rename the genpd subsystem to pmdomainUlf Hansson
It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. In a way to improve the situation, let's rename the subsystem to pmdomain, which ideally should indicate that this is about so called Power Domains or "PM domains" as we often also use within the Linux Kernel terminology.

2023-09-13i2c: I2C_MLXCPLD on ARM64 should depend on ACPIGeert Uytterhoeven
The "i2c_mlxcpld" platform device is only instantiated on X86 systems (through drivers/platform/x86/mlx-platform.c), or on ARM64 systems with ACPI (through drivers/platform/mellanox/nvsw-sn2201.c). Hence further restrict the dependency on ARM64 to ACPI, to prevent asking the user about this driver when configuring an ARM64 kernel without ACPI support. While at it, document in the Kconfig help text that the driver supports ARM64/ACPI based systems, too.

2023-09-13bus: ti-sysc: Fix SYSC_QUIRK_SWSUP_SIDLE_ACT handling for uart wake-upTony Lindgren
The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of SYSC_QUIRK_SWSUP_SIDLE_ACT. The difference is that SYSC_QUIRK_SWSUP_SIDLE is used to force idle target modules rather than block idle during usage. The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when a target module is active, and configure autoidle and wake-up when a target module is inactive. We are missing configuring the target module on sysc_disable_module(), and missing toggling of the wake-up bit. Let's fix the issue to allow uart wake-up to work.

This seems safe as rx and tx are both disabled anyway at this point. It is however not entirely clear what the spinlock shall protect. It could be the read-modify-write access to the NCFGR register, but this is accessed in macb_set_rx_mode() and macb_set_rxcsum_feature() as well without holding the spinlock. It could also be the register accesses done in mog_init_rings() or macb_init_buffers(), but again these functions are called without holding the spinlock in macb_hresp_error_task(). The locking seems fishy in this driver and it might deserve another look before this patch is applied.

2023-09-12drm/i915: Only check eDP HPD when AUX CH is sharedVille Syrjälä
Apparently Acer Chromebook C740 (BDW-ULT) doesn't have the eDP HPD line properly connected, and thus fails the new HPD check during eDP probe. The result is that we lose the eDP output. I suspect all such machines would be Chromebooks or other Linux exclusive systems as the Windows driver likely wouldn't work either. I did check a few other BDW machines here and those do have eDP HPD connected, one of them even is a different Chromebook (Samus). To account for these funky machines let's skip the HPD check when it looks like the eDP port is the only one using that specific AUX channel. In case of multiple ports sharing the same AUX CH (eg. on Asrock B250M-HDV) we still do the check and thus should correctly ignore the eDP port in favor of the other DP port (usually a DP->VGA converter). v2: Don't oops during list iteration Cc: stable@vger.kernel.org Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9264 Fixes: cfe5bdfb27fa ("drm/i915: Check HPD live state during eDP probe") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230908052527.685-1-ville.syrjala@linux.intel.com Reviewed-by: Luca Coelho <luciano.coelho@intel.com> (cherry picked from commit 70052100fabec5d8c1b09c9959817a2f4517e6b5) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
