2024-10-28net/mlx5: unique names for per device cachesSebastian Ott
Add the device name to the per device kmem_cache names to ensure their uniqueness. This fixes warnings like this: "kmem_cache of name 'mlx5_fs_fgs' already exists".

2024-10-28clk: sophgo: avoid integer overflow in sg2042_pll_recalc_rate()Zichen Xie
This was found by a static analyzer. There may be a potential integer overflow issue in sg2042_pll_recalc_rate(). numerator is defined as u64 while parent_rate is defined as unsigned long and ctrl_table.fbdiv is defined as unsigned int. On 32-bit machine, the result of the calculation will be limited to "u32" without correct casting. Integer overflow may occur on high-performance systems.

2024-10-28macsec: Fix use-after-free while sending the offloading packetJianbo Liu
KASAN reports the following UAF. The metadata_dst, which is used to store the SCI value for macsec offload, is already freed by metadata_dst_free() in macsec_free_netdev(), while driver still use it for sending the packet. To fix this issue, dst_release() is used instead to release metadata_dst. So it is not freed instantly in macsec_free_netdev() if still referenced by skb.

2024-10-28clk: eyeq: add driverThéo Lebrun
Add Mobileye EyeQ5, EyeQ6L and EyeQ6H clock controller driver. It is both a platform driver and a hook onto of_clk_init() used for clocks required early (GIC timer, UARTs). For some compatible, it is both at the same time. eqc_early_init() initialises early PLLs and exposes its own clock provider. It marks other clocks as deferred. eqc_probe() adds all remaining clocks using another clock provider. It exposes read-only PLLs derived from the main crystal on board. It also exposes another type of clocks: divider clocks. They always have even divisors and have one PLL as parent. This driver also bears the responsability for optional reset and pinctrl auxiliary devices. The match data attached to the devicetree node compatible indicate if such devices should be created. They all get passed a pointer to the start of the OLB region.

2024-10-28watchdog: Add HAS_IOPORT dependency for SBC8360 and SBC7240Niklas Schnelle
Both drivers use I/O port accesses without declaring a dependency on CONFIG_HAS_IOPORT. For sbc8360_wdt this causes a compile error on UML once inb()/outb() helpers become conditional. For sbc7240_wdt this causes no such errors with UML because this driver depends on both x86_32 and !UML. Nevertheless add HAS_IOPORT as a dependency for both drivers to be explicit and drop the !UML dependency for sbc7240_wdt as it is now redundant since UML implies no HAS_IOPORT.

Root cause appears that when GPU metrics tables for v2_4 parts were added it was not considered to enlarge the table to fit. The fix in this patch is rather "brute force" and perhaps later should be done in a smarter way, by extracting and consolidating the part version to size logic to a common helper, instead of brute forcing the largest possible allocation.

Root cause appears that when GPU metrics tables for v2_4 parts were added it was not considered to enlarge the table to fit. The fix in this patch is rather "brute force" and perhaps later should be done in a smarter way, by extracting and consolidating the part version to size logic to a common helper, instead of brute forcing the largest possible allocation. Nevertheless, for now this works and fixes the out of bounds write. v2: * Drop impossible v3_0 case.

2024-10-28drm/amd/display: store sharpness 1dlut table in dscl_prog_dataSamson Tam
[Why] Previously dscl_prog_data stored pointer to sharpness 1dlut table. SPL had four pre-generated tables, one for each setup. This allowed us to minimize number of times we had to recalculate table when switching between setups. However, with dual display, this becomes an issue because for a given setup, we could have a different per app sharpness value than the global sharpness value. So the pre-generated table will change but both displays may point to the same table and one of them will have the wrong sharpness setting. [How] Store the sharpness 1dlut table in dscl_prog_data. This ensures that each display can have its own sharpness setting.
