CLK_TO_US macro is used to calculate potential transfer time for various timeout handling. However it overflows on transfer bigger than 512 bytes because it first did (len * 8 * 1000000). This controller typically operates at 45MHz. This patch did 2 things: 1. calculate clock / 1000000 first 2. add a 4M transfer size cap so that the final timeout in DMA reading doesn't overflow Fixes: 881d1ee9fe81f ("spi: add support for mediatek spi-nor controller") Cc: <stable@vger.kernel.org> Signed-off-by: Chuanhong Guo <gch981213@gmail.com> Link: https://lore.kernel.org/r/20200922114905.2942859-1-gch981213@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>

2020-09-25usbcore/driver: Accommodate usbipM. Vefa Bicakci
Commit 88b7381a939d ("USB: Select better matching USB drivers when available") inadvertently broke usbip functionality. The commit in question allows USB device drivers to be explicitly matched with USB devices via the use of driver-provided identifier tables and match functions, which is useful for a specialised device driver to be chosen for a device that can also be handled by another, more generic, device driver. Prior, the USB device section of usb_device_match() had an unconditional "return 1" statement, which allowed user-space to bind USB devices to the usbip_host device driver, if desired. However, the aforementioned commit changed the default/fallback return value to zero. This breaks device drivers such as usbip_host, so this commit restores the legacy behaviour, but only if a device driver does not have an id_table and a match() function. In addition, if usb_device_match is called for a device driver and device pair where the device does not match the id_table of the device driver in question, then the device driver will be disqualified for the device. This allows avoiding the default case of "return 1", which prevents undesirable probe() calls to a driver even though its id_table did not match the device. Finally, this commit changes the specialised-driver-to-generic-driver transition code so that when a device driver returns -ENODEV, a more generic device driver is only considered if the current device driver does not have an id_table and a match() function. This ensures that "generic" drivers such as usbip_host will not be considered specialised device drivers and will not cause the device to be locked in to the generic device driver, when a more specialised device driver could be tried. All of these changes restore usbip functionality without regressions, ensure that the specialised/generic device driver selection logic works as expected with the usb and apple-mfi-fastcharge drivers, and do not negatively affect the use of devices provided by dummy_hcd.

2020-09-25usbcore/driver: Fix incorrect downcastM. Vefa Bicakci
This commit resolves a minor bug in the selection/discovery of more specific USB device drivers for devices that are currently bound to generic USB device drivers. The bug is related to the way a candidate USB device driver is compared against the generic USB device driver. The code in is_dev_usb_generic_driver() assumes that the device driver in question is a USB device driver by calling to_usb_device_driver(dev->driver) to downcast; however I have observed that this assumption is not always true, through code instrumentation. This commit avoids the incorrect downcast altogether by comparing the USB device's driver (i.e., dev->driver) to the generic USB device driver directly. This method was suggested by Alan Stern. This bug was found while investigating Andrey Konovalov's report indicating usbip device driver misbehaviour with the recently merged generic USB device driver selection feature. The report is linked below.

2020-09-25usbcore/driver: Fix specific driver selectionM. Vefa Bicakci
This commit resolves a bug in the selection/discovery of more specific USB device drivers for devices that are currently bound to generic USB device drivers. The bug is in the logic that determines whether a device currently bound to a generic USB device driver should be re-probed by a more specific USB device driver or not. The code in __usb_bus_reprobe_drivers() used to have the following lines: if (usb_device_match_id(udev, new_udriver->id_table) == NULL && (!new_udriver->match || new_udriver->match(udev) != 0)) return 0; ret = device_reprobe(dev); As the reader will notice, the code checks whether the USB device in consideration matches the identifier table (id_table) of a specific USB device_driver (new_udriver), followed by a similar check, but this time with the USB device driver's match function. However, the match function's return value is not checked correctly. When match() returns zero, it means that the specific USB device driver is *not* applicable to the USB device in question, but the code then goes on to reprobe the device with the new USB device driver under consideration. All this to say, the logic is inverted. This bug was found by code inspection and instrumentation while investigating the root cause of the issue reported by Andrey Konovalov, where usbip took over syzkaller's virtual USB devices in an undesired manner. The report is linked below.

2020-09-25Revert "usbip: Implement a match function to fix usbip"M. Vefa Bicakci
This commit reverts commit 7a2f2974f265 ("usbip: Implement a match function to fix usbip"). In summary, commit d5643d2249b2 ("USB: Fix device driver race") inadvertently broke usbip functionality, which I resolved in an incorrect manner by introducing a match function to usbip, usbip_match(), that unconditionally returns true. However, the usbip_match function, as is, causes usbip to take over virtual devices used by syzkaller for USB fuzzing, which is a regression reported by Andrey Konovalov. Furthermore, in conjunction with the fix of another bug, handled by another patch titled "usbcore/driver: Fix specific driver selection" in this patch set, the usbip_match function causes unexpected USB subsystem behaviour when the usbip_host driver is loaded. The unexpected behaviour can be qualified as follows: - If commit 41160802ab8e ("USB: Simplify USB ID table match") is included in the kernel, then all USB devices are bound to the usbip_host driver, which appears to the user as if all USB devices were disconnected. - If the same commit (41160802ab8e) is not in the kernel (as is the case with v5.8.10) then all USB devices are re-probed and re-bound to their original device drivers, which appears to the user as a disconnection and re-connection of USB devices. Please note that this commit will make usbip non-operational again, until yet another patch in this patch set is merged, titled "usbcore/driver: Accommodate usbip".

2020-09-25ice: fix memory leak in ice_vsi_setupJacob Keller
During ice_vsi_setup, if ice_cfg_vsi_lan fails, it does not properly release memory associated with the VSI rings. If we had used devres allocations for the rings, this would be ok. However, we use kzalloc and kfree_rcu for these ring structures. Using the correct label to cleanup the rings during ice_vsi_setup highlights an issue in the ice_vsi_clear_rings function: it can leave behind stale ring pointers in the q_vectors structure. When releasing rings, we must also ensure that no q_vector associated with the VSI will point to this ring again. To resolve this, loop over all q_vectors and release their ring mapping. Because we are about to free all rings, no q_vector should remain pointing to any of the rings in this VSI.

The ice_setup_pf_sw function can cause a memory leak if register_netdev fails, due to accidentally failing to free the VSI rings. Fix the memory leak by using ice_vsi_release, ensuring we actually go through the full teardown process. This should be safe even if the netdevice is not registered because we will have set the netdev pointer to NULL, ensuring ice_vsi_release won't call unregister_netdev. An alternative fix would be moving management of the PF VSI netdev into the main VSI setup code.

2020-09-25mmc: renesas_sdhi: drop local flag for tuningWolfram Sang
The MMC core has now a generic check if some tuning is in progress. Its protected area is a bit larger than the custom one in this driver but we concluded that this works equally well for the intended case. So, drop the local flag and switch to the generic one.

2020-09-25fbcon: Fix global-out-of-bounds read in fbcon_get_font()Peilin Ye
fbcon_get_font() is reading out-of-bounds. A malicious user may resize `vc->vc_font.height` to a large value, causing fbcon_get_font() to read out of `fontdata`. fbcon_get_font() handles both built-in and user-provided fonts. Fortunately, recently we have added FONT_EXTRA_WORDS support for built-in fonts, so fix it by adding range checks using FNTSIZE(). This patch depends on patch "fbdev, newport_con: Move FONT_EXTRA_WORDS macros into linux/font.h", and patch "Fonts: Support FONT_EXTRA_WORDS macros for built-in fonts".

drivers/video/console/newport_con.c is borrowing FONT_EXTRA_WORDS macros from drivers/video/fbdev/core/fbcon.h. To keep things simple, move all definitions into <linux/font.h>. Since newport_con now uses four extra words, initialize the fourth word in newport_set_font() properly.
