[PATCH V3] init: Handle bootloader identifier in kernel parameters

by Huacai Chen

BootLoader (Grub, LILO, etc) may pass an identifier such as "BOOT_IMAGE= /boot/vmlinuz-x.y.z" to kernel parameters. But these identifiers are not recognized by the kernel itself so will be passed to user space. However user space init program also doesn't recognized it. KEXEC/KDUMP (kexec-tools) may also pass an identifier such as "kexec" on some architectures. We cannot change BootLoader's behavior, because this behavior exists for many years, and there are already user space programs search BOOT_IMAGE= in /proc/cmdline to obtain the kernel image locations: https://github.com/linuxdeepin/deepin-ab-recovery/blob/master/util.go (search getBootOptions) https://github.com/linuxdeepin/deepin-ab-recovery/blob/master/main.go (search getKernelReleaseWithBootOption) So the the best way is handle (ignore) it by the kernel itself, which can avoid such boot warnings (if we use something like init=/bin/bash, bootloader identifier can even cause a crash): Kernel command line: BOOT_IMAGE=(hd0,1)/vmlinuz-6.x root=/dev/sda3 ro console=tty Unknown kernel command line parameters "BOOT_IMAGE=(hd0,1)/vmlinuz-6.x", will be passed to user space.

[PATCH v3] wifi: mwifiex: Initialize the chan_stats array to zero

by Qianfeng Rong

The adapter->chan_stats[] array is initialized in mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out memory. The array is filled in mwifiex_update_chan_statistics() and then the user can query the data in mwifiex_cfg80211_dump_survey(). There are two potential issues here. What if the user calls mwifiex_cfg80211_dump_survey() before the data has been filled in. Also the mwifiex_update_chan_statistics() function doesn't necessarily initialize the whole array. Since the array was not initialized at the start that could result in an information leak. Also this array is pretty small. It's a maximum of 900 bytes so it's more appropriate to use kcalloc() instead vmalloc().

[PATCH] xen/events: Fix Global and Domain VIRQ tracking

by Jason Andryuk

VIRQs come in 3 flavors, per-VPU, per-domain, and global. The existing tracking of VIRQs is handled by per-cpu variables virq_to_irq. The issue is that bind_virq_to_irq() sets the per_cpu virq_to_irq at registration time - typically CPU 0. Later, the interrupt can migrate, and info->cpu is updated. When calling unbind_from_irq(), the per-cpu virq_to_irq is cleared for a different cpu. If bind_virq_to_irq() is called again with CPU 0, the stale irq is returned. Change the virq_to_irq tracking to use CPU 0 for per-domain and global VIRQs. As there can be at most one of each, there is no need for per-vcpu tracking. Also, per-domain and global VIRQs need to be registered on CPU 0 and can later move, so this matches the expectation. Fixes: e46cdb66c8fc ("xen: event channels") Cc: stable(a)vger.kernel.org Signed-off-by: Jason Andryuk <jason.andryuk(a)amd.com> --- Fixes is the introduction of the virq_to_irq per-cpu array. This was found with the out-of-tree argo driver during suspend/resume. On suspend, the per-domain VIRQ_ARGO is unbound. On resume, the driver attempts to bind VIRQ_ARGO. The stale irq is returned, but the WARN_ON(info == NULL || info->type != IRQT_VIRQ) in bind_virq_to_irq() triggers for NULL info. The bind fails and execution continues with the driver trying to clean up by unbinding. This eventually faults over the NULL info. --- drivers/xen/events/events_base.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/drivers/xen/events/events_base.c b/drivers/xen/events/events_base.c index 41309d38f78c..a27e4d7f061e 100644 --- a/drivers/xen/events/events_base.c +++ b/drivers/xen/events/events_base.c @@ -159,7 +159,19 @@ static DEFINE_MUTEX(irq_mapping_update_lock); static LIST_HEAD(xen_irq_list_head); -/* IRQ <-> VIRQ mapping. */ +static bool is_per_vcpu_virq(int virq) { + switch (virq) { + case VIRQ_TIMER: + case VIRQ_DEBUG: + case VIRQ_XENOPROF: + case VIRQ_XENPMU: + return true; + default: + return false; + } +} + +/* IRQ <-> VIRQ mapping.

[PATCH 2/5] HID: apple: validate feature-report field count to prevent NULL pointer dereference

by malepudileep.111＠gmail.com

From: Qasim Ijaz <qasdev00(a)gmail.com> commit 1bb3363da862e0464ec050eea2fb5472a36ad86b upstream. A malicious HID device with quirk APPLE_MAGIC_BACKLIGHT can trigger a NULL pointer dereference whilst the power feature-report is toggled and sent to the device in apple_magic_backlight_report_set(). The power feature-report is expected to have two data fields, but if the descriptor declares one field then accessing field[1] and dereferencing it in apple_magic_backlight_report_set() becomes invalid since field[1] will be NULL. An example of a minimal descriptor which can cause the crash is something like the following where the report with ID 3 (power report) only references a single 1-byte field. When hid core parses the descriptor it will encounter the final feature tag, allocate a hid_report (all members of field[] will be zeroed out), create field structure and populate it, increasing the maxfield to 1. The subsequent field[1] access and dereference causes the crash.

[PATCH v3 1/4] LoongArch: KVM: Fix stack protector issue in send_ipi_data()

by Bibo Mao

Function kvm_io_bus_read() is called in function send_ipi_data(), buffer size of parameter *val should be at least 8 bytes. Some emulation functions like loongarch_ipi_readl() and kvm_eiointc_read() will write buffer *val with 8 bytes signed extension regardless parameter len. Otherwise there will be buffer overflow issue when CONFIG_STACKPROTECTOR is enabled.

[PATCH 6.15] wifi: ath12k: install pairwise key first

by Baochen Qiang

[ Upstream commit 66e865f9dc78d00e6d1c8c6624cb0c9004e5aafb ] As station, WCN7850 firmware requires pairwise key to be installed before group key. Currently host does not care about this, so it is up to kernel or userspace to decide which one will be installed first. In case above requirement is not met, WCN7850 firmware's EAPOL station machine is messed up, and finally connection fails [1]. Reorder key install for station interface in that case: this is done by caching group key first; Later when pairwise key arrives, both can be installed in required order.

[PATCH v3] usb: dwc3: Remove WARN_ON for device endpoint command timeouts

by Selvarasu Ganesan

This commit addresses a rarely observed endpoint command timeout which causes kernel panic due to warn when 'panic_on_warn' is enabled and unnecessary call trace prints when 'panic_on_warn' is disabled. It is seen during fast software-controlled connect/disconnect testcases. The following is one such endpoint command timeout that we observed: 1. Connect ======= ->dwc3_thread_interrupt ->dwc3_ep0_interrupt ->configfs_composite_setup ->composite_setup ->usb_ep_queue ->dwc3_gadget_ep0_queue ->__dwc3_gadget_ep0_queue ->__dwc3_ep0_do_control_data ->dwc3_send_gadget_ep_cmd 2. Disconnect ========== ->dwc3_thread_interrupt ->dwc3_gadget_disconnect_interrupt ->dwc3_ep0_reset_state ->dwc3_ep0_end_control_data ->dwc3_send_gadget_ep_cmd In the issue scenario, in Exynos platforms, we observed that control transfers for the previous connect have not yet been completed and end transfer command sent as a part of the disconnect sequence and processing of USB_ENDPOINT_HALT feature request from the host timeout. This maybe an expected scenario since the controller is processing EP commands sent as a part of the previous connect. It maybe better to remove WARN_ON in all places where device endpoint commands are sent to avoid unnecessary kernel panic due to warn.
