[PATCH net 2/3] net: libwx: fix the using of Rx buffer DMA

by Jiawen Wu

The wx_rx_buffer structure contained two DMA address fields: 'dma' and 'page_dma'. However, only 'page_dma' was actually initialized and used to program the Rx descriptor. But 'dma' was uninitialized and used in some paths. This could lead to undefined behavior, including DMA errors or use-after-free, if the uninitialized 'dma' was used. Althrough such error has not yet occurred, it is worth fixing in the code.

[BACKPORT][PATCH 6.12.y 1/2] firmware: arm_ffa: Move memory allocation outside the mutex locking

by Sudeep Holla

[ Upstream commit 27e850c88df0e25474a8caeb2903e2e90b62c1dc ] The notifier callback node allocation is currently done while holding the notify_lock mutex. While this is safe even if memory allocation may sleep, we need to move the allocation outside the locked region in preparation to move from using muxtes to rwlocks. Move the memory allocation to avoid potential sleeping in atomic context once the locks are moved from mutex to rwlocks.

[PATCH 6.12,6.15] crypto: s390/sha - Fix uninitialized variable in SHA-1 and SHA-2

by Eric Biggers

commit 68279380266a5fa70e664de754503338e2ec3f43 upstream. Commit 88c02b3f79a6 ("s390/sha3: Support sha3 performance enhancements") added the field s390_sha_ctx::first_message_part and made it be used by s390_sha_update() (now s390_sha_update_blocks()). At the time, s390_sha_update() was used by all the s390 SHA-1, SHA-2, and SHA-3 algorithms. However, only the initialization functions for SHA-3 were updated, leaving SHA-1 and SHA-2 using first_message_part uninitialized. This could cause e.g. the function code CPACF_KIMD_SHA_512 | CPACF_KIMD_NIP to be used instead of just CPACF_KIMD_SHA_512. This apparently was harmless, as the SHA-1 and SHA-2 function codes ignore CPACF_KIMD_NIP; it is recognized only by the SHA-3 function codes (https://lore.kernel.org/r/73477fe9-a1dc-4e38-98a6-eba9921e8afa@linux.ibm.co…). Therefore, this bug was found only when first_message_part was later converted to a boolean and UBSAN detected its uninitialized use. Regardless, let's fix this by just initializing to zero. Note: in 6.16, we need to patch SHA-1, SHA-384, and SHA-512. In 6.15 and earlier, we'll also need to patch SHA-224 and SHA-256, as they hadn't yet been librarified (which incidentally fixed this bug).

[PATCH] arm64: dts: ti: k3-j722s-evm: Fix USB gpio-hog level for Type-C

by Siddharth Vadapalli

According to the "GPIO Expander Map / Table" section of the J722S EVM Schematic within the Evaluation Module Design Files package [0], the GPIO Pin P05 located on the GPIO Expander 1 (I2C0/0x23) has to be pulled down to select the Type-C interface. Since commit under Fixes claims to enable the Type-C interface, update the property within "p05-hog" from "output-high" to "output-low", thereby switching from the Type-A interface to the Type-C interface.

[PATCH] drm/panfrost: Fix scheduler workqueue bug

by Philipp Stanner

When the GPU scheduler was ported to using a struct for its initialization parameters, it was overlooked that panfrost creates a distinct workqueue for timeout handling. The pointer to this new workqueue is not initialized to the struct, resulting in NULL being passed to the scheduler, which then uses the system_wq for timeout handling. Set the correct workqueue to the init args struct.

Frames that fail this check are discarded early, preventing them from reaching the MLME layer and triggering WARN_ON(). This filtering logic is similar with that used in the ieee80211_rx_mgmt_disassoc() function in mac80211, which drops disassoc frames that don't match the current BSSID (!ether_addr_equal(mgmt->bssid, sdata->vif.cfg.ap_addr)), ensuring only relevant frames are processed.

[PATCH v4 2/2] PCI: imx6: Align EP link start behavior with documentation

by Richard Zhu

According to PCI/endpoint/pci-endpoint-cfs.rst, the endpoint (EP) should only link up after `echo 1 > start` is executed. To match the documented behavior, do not start the link automatically when adding the EP controller.

[PATCH v4 1/2] PCI: imx6: Remove apps_reset toggle in _core_reset functions

by Richard Zhu

apps_reset is LTSSM_EN on i.MX7, i.MX8MQ, i.MX8MM and i.MX8MP platforms. Since the assertion/de-assertion of apps_reset(LTSSM_EN bit) had been wrappered in imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable(); Remove apps_reset toggle in imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset() functions. Use imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable() to configure apps_reset directly. Fix fail to enumerate reliably PI7C9X2G608GP (hotplug) at i.MX8MM, which reported By Tim. Only i.MX7D, i.MX8MQ, i.MX8MM, and i.MX8MP have the apps_reset. With this change, the assertion/deassertion of LTSSM_EN bit are unified into imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable() functions, and aligned with other i.MX platforms.
