[PATCH 1/3] perf/x86: Fix low freq setting issue

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> Perf doesn't work with a low freq. perf record -e cpu_core/instructions/ppp -F 120 Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_core/instructions/ppp). "dmesg | grep -i perf" may provide additional information. The limit_period() check avoids a low sampling period on a counter. It doesn't intend to limit the frequency. The check in the x86_pmu_hw_config() should be limited to non-freq mode. The … [View More]

[PATCH] perf: Add RCU read lock protection to perf_iterate_ctx()

The perf_iterate_ctx() function performs RCU list traversal but currently lacks RCU read lock protection.

[PATCH AUTOSEL 6.10 01/27] wifi: nl80211: disallow setting special AP channel widths

by Sasha Levin

From: Johannes Berg <johannes.berg(a)intel.com> [ Upstream commit 23daf1b4c91db9b26f8425cc7039cf96d22ccbfe ] Setting the AP channel width is meant for use with the normal 20/40/... MHz channel width progression, and switching around in S1G or narrow channels isn't supported. Disallow that.

[PATCH 0/2] A couple of build fixes for x86 when using GCC 15

by Nathan Chancellor

Hi all, GCC 15 changed the default C standard version from gnu17 to gnu23, which reveals a few places in the kernel where a C standard version was not set, resulting in build failures because bool, true, and false are reserved keywords in C23 [1][2]. Update these places to use the same C standard version as the rest of the kernel, gnu11.

[PATCH] PCI: endpoint: Fix a double free in __pci_epc_create()

by Ma Ke

The put_device(&epc->dev) call will trigger pci_epc_release() which frees "epc" so the kfree(epc) on the next line is a double free. Found by code review.

[PATCH 4/4] char: misc: deallocate static minor in error path

by Thadeu Lima de Souza Cascardo

When creating sysfs files fail, the allocated minor must be freed such that it can be later reused. That is specially harmful for static minor numbers, since those would always fail to register later on.

This can lead to endless list iterations and a subsequent crash. The queue_lock is supposed to be used only for queue lists belonging to dasd_block. For dasd_device related queue lists the ccwdev lock must be used. Fix the mentioned issues by correctly using the ccwdev lock instead of the queue lock.
