nonstatic_find_mem_region() In nonstatic_find_mem_region(), pcmcia_make_resource() is assigned to res and used in pci_bus_alloc_resource(). There a dereference of res in pci_bus_alloc_resource(), which could lead to a NULL pointer dereference on failure of pcmcia_make_resource(). Fix this bug by adding a check of res. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_PCCARD_NONSTATIC=y show no new warnings, and our static analyzer no longer warns about this code.

2022-01-02rndis_host: support Hytera digital radiosThomas Toye
Hytera makes a range of digital (DMR) radios. These radios can be programmed to a allow a computer to control them over Ethernet over USB, either using NCM or RNDIS. This commit adds support for RNDIS for Hytera radios. I tested with a Hytera PD785 and a Hytera MD785G. When these radios are programmed to set up a Radio to PC Network using RNDIS, an USB interface will be added with class 2 (Communications), subclass 2 (Abstract Modem Control) and an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT RNDIS?"). This patch is similar to the solution of this StackOverflow user, but that only works for the Hytera MD785: https://stackoverflow.com/a/53550858 To use the "Radio to PC Network" functionality of Hytera DMR radios, the radios need to be programmed correctly in CPS (Hytera's Customer Programming Software). "Forward to PC" should be checked in "Network" (under "General Setting" in "Conventional") and the "USB Network Communication Protocol" should be set to RNDIS.

2022-01-02net: ena: Fix error handling when calculating max IO queues numberArthur Kiyanovski
The role of ena_calc_max_io_queue_num() is to return the number of queues supported by the device, which means the return value should be >=0. The function that calls ena_calc_max_io_queue_num(), checks the return value. If it is 0, it means the device reported it supports 0 IO queues. This case is considered an error and is handled by the calling function accordingly. However the current implementation of ena_calc_max_io_queue_num() is wrong, since when it detects the device supports 0 IO queues, it returns -EFAULT. In such a case the calling function doesn't detect the error, and therefore doesn't handle it. This commit changes ena_calc_max_io_queue_num() to return 0 in case the device reported it supports 0 queues, allowing the calling function to properly handle the error case.

2022-01-02net: ena: Fix undefined state when tx request id is out of boundsArthur Kiyanovski
ena_com_tx_comp_req_id_get() checks the req_id of a received completion, and if it is out of bounds returns -EINVAL. This is a sign that something is wrong with the device and it needs to be reset. The current code does not reset the device in this case, which leaves the driver in an undefined state, where this completion is not properly handled. This commit adds a call to handle_invalid_req_id() in ena_clean_tx_irq() and ena_clean_xdp_irq() which resets the device to fix the issue. This commit also removes unnecessary request id checks from validate_tx_req_id() and validate_xdp_req_id(). This check is unneeded because it was already performed in ena_com_tx_comp_req_id_get(), which is called right before these functions.

2021-12-31net: hns3: refactor hns3 makefile to support hns3_common moduleJie Wang
Currently we plan to refactor PF and VF cmdq module. A new file folder hns3_common will be created to store new common APIs used by PF and VF cmdq module. Thus the PF and VF compilation process will both depends on the hns3_common. This may cause parallel building problems if we add a new makefile building unit. So this patch combined the PF and VF makefile scripts to the top level makefile to support the new hns3_common which will be created in the next patch.

2021-12-31drm/amdgpu: disable runpm if we are the primary adapterAlex Deucher
If we are the primary adapter (i.e., the one used by the firwmare framebuffer), disable runtime pm. This fixes a regression caused by commit 55285e21f045 which results in the displays waking up shortly after they go to sleep due to the device coming out of runtime suspend and sending a hotplug uevent. v2: squash in reworked fix from Evan Fixes: 55285e21f045 ("fbdev/efifb: Release PCI device's runtime PM ref during FB destroy") Bug: https://bugzilla.kernel.org/show_bug.cgi?id=215203 Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1840 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2021-12-31fbdev: fbmem: add a helper to determine if an aperture is used by a fw fbAlex Deucher
Add a function for drivers to check if the a firmware initialized fb is corresponds to their aperture. This allows drivers to check if the device corresponds to what the firmware set up as the display device.

2021-12-31i2c: validate user data in compat ioctlPavel Skripkin
Wrong user data may cause warning in i2c_transfer(), ex: zero msgs. Userspace should not be able to trigger warnings, so this patch adds validation checks for user data in compact ioctl to prevent reported warnings Reported-and-tested-by: syzbot+e417648b303855b91d8a@syzkaller.appspotmail.com Fixes: 7d5cb45655f2 ("i2c compat ioctls: move to ->compat_ioctl()") Signed-off-by: Pavel Skripkin <paskripkin@gmail.com> Signed-off-by: Wolfram Sang <wsa@kernel.org>

SPI NOR core changes: - Add Pratyush as SPI NOR co-maintainer. - Flash parameters initialization was done in a spaghetti way. Clean flash parameters initialization. - Rework the flash_info flags and clarify where one should be used. - Initialize all flash parameters based on JESD216 SFDP where possible. Flash parameters and settings that are SFDP discoverable should not be duplicated via flash_info flags at flash declaration. - Remove debugfs entries that duplicate sysfs entries. SPI NOR manufacturer drivers changes: - Use late_init() hook in various drivers to make it clear that those flash parameters are either not declared in the JESD216 SFDP standard, or the SFDP tables which define those flash parameters are not defined by the flash. - Fix mtd size for s3an flashes. - Write 2 bytes when disabling Octal DTR mode: 1 byte long transactions are not allowed in 8D-8D-8D mode.
