2024-05-14Bluetooth: btqcomsmd: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2024-05-14net: micrel: Fix receiving the timestamp in the frame for lan8841Horatiu Vultur
The blamed commit started to use the ptp workqueue to get the second part of the timestamp. And when the port was set down, then this workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING is not enabled, then the ptp_clock is not initialized so then it would crash when it would try to access the delayed work. So then basically by setting up and then down the port, it would crash. The fix consists in checking if the ptp_clock is initialized and only then cancel the delayed work.

Pull DSA and IAA accelerator mis-alignment fix from Arjan van de Ven: "The DSA (memory copy/zero/etc) and IAA (compression) accelerators in the Sapphire Rapids and Emerald Rapids SOCs turn out to have a bug that has security implications. Both of these accelerators work by the application submitting a 64 byte command to the device; this command contains an opcode as well as the virtual address of the return value that the device will update on completion... and a set of opcode specific values. In a typical scenario a ring 3 application mmaps the device file and uses the ENQCMD or MOVDIR64 instructions (which are variations of a 64 byte atomic write) on this mmap'd memory region to directly submit commands to a device hardware. The return value as specified in the command, is supposed to be 32 (or 64) bytes aligned in memory, and generally the hardware checks and enforces this alignment. However in testing it has been found that there are conditions (controlled by the submitter) where this enforcement does not happen... which makes it possible for the return value to span a page boundary. And this is where it goes wrong - the accelerators will perform the virtual to physical address lookup on the first of the two pages, but end up continue writing to the next consecutive physical (host) page rather than the consecutive virtual page. In addition, the device will end up in a hung state on such unaligned write of the return value. This patch series has the proposed software side solution consisting of three parts: - Don't allow these two PCI devices to be assigned to VM guests (we cannot trust a VM guest to behave correctly and not cause this condition) - Don't allow ring 3 applications to set up the mmap unless they have CAP_SYS_RAWIO permissions. This makes it no longer possible for non-root applications to directly submit commands to the accelerator - Add a write() method to the device so that an application can submit its commands to the kernel driver, which performs the needed sanity checks before submitting it to the hardware. This switch from mmap to write is an incompatible interface change to non-root userspace, but we have not found a way to avoid this. All software we know of uses a small set of accessor libraries for these accelerators, for which libqpl and libdml (on github) are the most common. As part of the security release, updated versions of these libraries will be released that transparently fall back to write().

2024-05-13net: prestera: Add flex arrays to some structsErick Archer
The "struct prestera_msg_vtcam_rule_add_req" uses a dynamically sized set of trailing elements. Specifically, it uses an array of structures of type "prestera_msg_acl_action actions_msg". The "struct prestera_msg_flood_domain_ports_set_req" also uses a dynamically sized set of trailing elements. Specifically, it uses an array of structures of type "prestera_msg_acl_action actions_msg". So, use the preferred way in the kernel declaring flexible arrays [1]. At the same time, prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). In this case, it is important to note that the attribute used is specifically __counted_by_le since the counters are of type __le32. The logic does not need to change since the counters for the flexible arrays are asigned before any access to the arrays. The order in which the structure prestera_msg_vtcam_rule_add_req and the structure prestera_msg_flood_domain_ports_set_req are defined must be changed to avoid incomplete type errors. Also, avoid the open-coded arithmetic in memory allocator functions [2] using the "struct_size" macro. Moreover, the new structure members also allow us to avoid the open- coded arithmetic on pointers. So, take advantage of this refactoring accordingly. This code was detected with the help of Coccinelle, and audited and modified manually.

2024-05-13net: fec: remove .ndo_poll_controller to avoid deadlocksWei Fang
There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so fec_poll_controller() can be safely removed.

2024-05-13net: stmmac: Make stmmac_xpcs_setup() generic to all PCS devicesSerge Semin
A pcs_init() callback will be introduced to stmmac in a future patch. This new function will be called during the hardware initialization phase. Instead of separately initializing XPCS and PCS components, let's group all PCS-related hardware initialization logic in the current stmmac_xpcs_setup() function. Rename stmmac_xpcs_setup() to stmmac_pcs_setup() and move the conditional call to stmmac_xpcs_setup() inside the function itself.

2024-05-13net: stmmac: Add dedicated XPCS cleanup methodSerge Semin
Currently the XPCS handler destruction is performed in the stmmac_mdio_unregister() method. It doesn't look good because the handler isn't originally created in the corresponding protagonist stmmac_mdio_unregister(), but in the stmmac_xpcs_setup() function. In order to have more coherent MDIO and XPCS setup/cleanup procedures, let's move the DW XPCS destruction to the dedicated stmmac_pcs_clean() method. This method will also be used to cleanup PCS hardware using the pcs_exit() callback that will be introduced to stmmac in a subsequent patch.

2024-05-13net/mlx5: Enable 8 ports LAGShay Drory
This patch adds to mlx5 drivers support for 8 ports HCAs. Starting with ConnectX-8 HCAs with 8 ports are possible. As most driver parts aren't affected by such configuration most driver code is unchanged. Specially the only affected areas are: - Lag - Multiport E-Switch - Single FDB E-Switch All of the above are already factored in generic way, and LAG and VF LAG are tested, so all that left is to change a #define and remove checks which are no longer needed. However, Multiport E-Switch is not tested yet, so it is left untouched. This patch will allow to create hardware LAG/VF LAG when all 8 ports are added to the same bond device. for example, In order to activate the hardware lag a user can execute the following: ip link add bond0 type bond ip link set bond0 type bond miimon 100 mode 2 ip link set eth2 master bond0 ip link set eth3 master bond0 ip link set eth4 master bond0 ip link set eth5 master bond0 ip link set eth6 master bond0 ip link set eth7 master bond0 ip link set eth8 master bond0 ip link set eth9 master bond0 Where eth2, eth3, eth4, eth5, eth6, eth7, eth8 and eth9 are the PFs of the same HCA.

2024-05-13net: usb: ax88179_178a: fix link status when link is set to down/upJose Ignacio Tornos Martinez
The idea was to keep only one reset at initialization stage in order to reduce the total delay, or the reset from usbnet_probe or the reset from usbnet_open. I have seen that restarting from usbnet_probe is necessary to avoid doing too complex things. But when the link is set to down/up (for example to configure a different mac address) the link is not correctly recovered unless a reset is commanded from usbnet_open. So, detect the initialization stage (first call) to not reset from usbnet_open after the reset from usbnet_probe and after this stage, always reset from usbnet_open too (when the link needs to be rechecked). Apply to all the possible devices, the behavior now is going to be the same. cc: stable@vger.kernel.org # 6.6+ Fixes: 56f78615bcb1 ("net: usb: ax88179_178a: avoid writing the mac address before first reading") Reported-by: Isaac Ganoung <inventor500@vivaldi.net> Reported-by: Yongqin Liu <yongqin.liu@linaro.org> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://lore.kernel.org/r/20240510090846.328201-1-jtornosm@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
