[PATCH v3] mips: Add -std= flag specified in KBUILD_CFLAGS to vdso CFLAGS

by Khem Raj

GCC 15 changed the default C standard dialect from gnu17 to gnu23, which should not have impacted the kernel because it explicitly requests the gnu11 standard in the main Makefile. However, mips/vdso code uses its own CFLAGS without a '-std=' value, which break with this dialect change because of the kernel's own definitions of bool, false, and true conflicting with the C23 reserved keywords. include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant 11 | false = 0, | ^~~~~ include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards include/linux/types.h:35:33: error: 'bool' cannot be defined via 'typedef' 35 | typedef _Bool bool; | ^~~~ include/linux/types.h:35:33: note: 'bool' is a keyword with '-std=c23' onwards Add -std as specified in KBUILD_CFLAGS to the decompressor and purgatory CFLAGS to eliminate these errors and make the C standard version of these areas match the rest of the kernel.

[PATCH v2] usb: dwc3: Abort suspend on soft disconnect failure

by Kuen-Han Tsai

When dwc3_gadget_soft_disconnect() fails, dwc3_suspend_common() keeps going with the suspend, resulting in a period where the power domain is off, but the gadget driver remains connected. Within this time frame, invoking vbus_event_work() will cause an error as it attempts to access DWC3 registers for endpoint disabling after the power domain has been completely shut down. Abort the suspend sequence when dwc3_gadget_suspend() cannot halt the controller and proceeds with a soft connect.

[PATCH v2] media: ov2740: Move pm-runtime cleanup on probe-errors to proper place

by Hans de Goede

When v4l2_subdev_init_finalize() fails no changes have been made to the runtime-pm device state yet, so the probe_error_media_entity_cleanup rollback path should not touch the runtime-pm device state. Instead this should be done from the probe_error_v4l2_subdev_cleanup rollback path. Note the pm_runtime_xxx() calls are put above the v4l2_subdev_cleanup() call to have the reverse call order of probe().

[PATCH v1] HID: usbhid: Eliminate recurrent out-of-bounds bug in usbhid_parse()

by Terry Junge

Update struct hid_descriptor to better reflect the mandatory and optional parts of the HID Descriptor as per USB HID 1.11 specification. Note: the kernel currently does not parse any optional HID class descriptors, only the mandatory report descriptor. Update all references to member element desc[0] to rpt_desc. Add test to verify bLength and bNumDescriptors values are valid. Replace the for loop with direct access to the mandatory HID class descriptor member for the report descriptor. This eliminates the possibility of getting an out-of-bounds fault. Add a warning message if the HID descriptor contains any unsupported optional HID class descriptors.

[PATCH v4 5/6] media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval

by Mathis Foerst

Getting / Setting the frame interval using the V4L2 subdev pad ops get_frame_interval/set_frame_interval causes a deadlock, as the subdev state is locked in the [1] but also in the driver itself. In [2] it's described that the caller is responsible to acquire and release the lock in this case. Therefore, acquiring the lock in the driver is wrong. Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval() and mt9m114_ifp_set_frame_interval().

[PATCH 6.1&6.6 V3 0/3] sign-file,extract-cert: switch to PROVIDER API for OpenSSL >= 3.0

by Huacai Chen

Backport this series to 6.1&6.6 because we get build errors with GCC14 and OpenSSL3 (or later): certs/extract-cert.c: In function 'main': certs/extract-cert.c:124:17: error: implicit declaration of function 'ENGINE_load_builtin_engines' [-Wimplicit-function-declaration] 124 | ENGINE_load_builtin_engines(); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ certs/extract-cert.c:126:21: error: implicit declaration of function 'ENGINE_by_id' [-Wimplicit-function-declaration] 126 | e = ENGINE_by_id("pkcs11"); | ^~~~~~~~~~~~ certs/extract-cert.c:126:19: error: assignment to 'ENGINE *' {aka 'struct engine_st *'} from 'int' makes pointer from integer without a cast [-Wint-conversion] 126 | e = ENGINE_by_id("pkcs11"); | ^ certs/extract-cert.c:128:21: error: implicit declaration of function 'ENGINE_init' [-Wimplicit-function-declaration] 128 | if (ENGINE_init(e)) | ^~~~~~~~~~~ certs/extract-cert.c:133:30: error: implicit declaration of function 'ENGINE_ctrl_cmd_string' [-Wimplicit-function-declaration] 133 | ERR(!ENGINE_ctrl_cmd_string(e, "PIN", key_pass, 0), "Set PKCS#11 PIN"); | ^~~~~~~~~~~~~~~~~~~~~~ certs/extract-cert.c:64:32: note: in definition of macro 'ERR' 64 | bool __cond = (cond); \ | ^~~~ certs/extract-cert.c:134:17: error: implicit declaration of function 'ENGINE_ctrl_cmd' [-Wimplicit-function-declaration] 134 | ENGINE_ctrl_cmd(e, "LOAD_CERT_CTRL", 0, &parms, NULL, 1); | ^~~~~~~~~~~~~~~ In theory 5.4&5.10&5.15 also need this, but they need more efforts because file paths are different. The ENGINE interface has its limitations and it has been superseded by the PROVIDER API, it is deprecated in OpenSSL version 3.0. Some distros have started removing it from header files. Update sign-file and extract-cert to use PROVIDER API for OpenSSL Major >= 3. Tested on F39 with openssl-3.1.1, pkcs11-provider-0.5-2, openssl-pkcs11-0.4.12-4 and softhsm-2.6.1-5 by using same key/cert as PEM and PKCS11 and comparing that the result is identical. V1 -> V2: Add upstream commit id. V2 -> V3: Add correct version id. Jan Stancek (3): sign-file,extract-cert: move common SSL helper functions to a header sign-file,extract-cert: avoid using deprecated ERR_get_error_line() sign-file,extract-cert: use pkcs11 provider for OPENSSL MAJOR >= 3 Signed-off-by: Jan Stancek <jstancek(a)redhat.com> Signed-off-by: Huacai Chen <chenhuacai(a)loongson.cn> --- MAINTAINERS | 1 + certs/Makefile | 2 +- certs/extract-cert.c | 138 +++++++++++++++++++++++-------------------- scripts/sign-file.c | 134 +++++++++++++++++++++-------------------- scripts/ssl-common.h | 32 ++++++++++ 5 files changed, 178 insertions(+), 129 deletions(-) create mode 100644 scripts/ssl-common.h --- 2.27.0
