But membarrier() uses an IPI and sets the PREEMPT bit in the event mask from the IPI, which leaves that RMW operation unprotected. Use guard(irq) if CONFIG_MEMBARRIER is enabled to fix that.

[PATCH net 01/10] can: gs_usb: increase max interface to U8_MAX

by Marc Kleine-Budde

From: Celeste Liu <uwu(a)coelacanthus.name> This issue was found by Runcheng Lu when develop HSCanT USB to CAN FD converter[1]. The original developers may have only 3 interfaces device to test so they write 3 here and wait for future change. During the HSCanT development, we actually used 4 interfaces, so the limitation of 3 is not enough now. But just increase one is not future-proofed. Since the channel index type in gs_host_frame is u8, just make canch[] become a flexible array with a u8 index, so it naturally constraint by U8_MAX and avoid statically allocate 256 pointer for every gs_usb device.

[PATCH] clk: rockchip: rk3588: Don't change PLL rates when setting dclk_vop2_src

by Heiko Stuebner

dclk_vop2_src currently has CLK_SET_RATE_PARENT | CLK_SET_RATE_NO_REPARENT flags set, which is vastly different than dclk_vop0_src or dclk_vop1_src, which have none of those. With these flags in dclk_vop2_src, actually setting the clock then results in a lot of other peripherals breaking, because setting the rate results in the PLL source getting changed: [ 14.898718] clk_core_set_rate_nolock: setting rate for dclk_vop2 to 152840000 [ 15.155017] clk_change_rate: setting rate for pll_gpll to 1680000000 [ clk adjusting every gpll user ] This includes possibly the other vops, i2s, spdif and even the uarts. Among other possible things, this breaks the uart console on a board I use. Sometimes it recovers later on, but there will be a big block of garbled output for a while at least. Shared PLLs should not be changed by individual users, so drop these flags from dclk_vop2_src and make the flags the same as on dclk_vop0 and dclk_vop1.

However, when the listener is removed, while transport goes away, rpcbind still has the entry for that port/type. When deleting the transport, unregister with rpcbind when appropriate. ---v2 created a new xpt_flag XPT_RPCB_UNREG to mark TCP and UDP transport and at xprt destroy send rpcbind unregister if flag set.

El feedback efectivo empieza con datos claros

by Daniel Rodríguez

Fortalece la evaluación del desempeño Fortalece la evaluación del desempeño con Vorecol 360 Feedback. Hola, , La retroalimentación es una de las herramientas más poderosas para el desarrollo de las personas, pero muchas veces se limita a la opinión de un solo líder. Con una visión más amplia, las decisiones se vuelven más justas y efectivas. Vorecol 360 Feedback te permite evaluar el desempeño desde múltiples perspectivas, obteniendo una imagen completa y objetiva. Con Vorecol 360 Feedback puedes: • Recibir evaluaciones desde diferentes fuentes: líderes, pares, colaboradores y autoevaluación. • Personalizar competencias y criterios según el rol y las metas de la organización. • Generar reportes claros y accionables, con áreas de mejora y fortalezas destacadas. Esto ayuda a crear una cultura de retroalimentación continua y mejora constante en todos los niveles. Si estás buscando fortalecer la evaluación del desempeño, esta puede ser una muy buena opción. Si quieres conocer más puedes responder este correo o simplemente contactarme, mis datos están abajo o da clic aquí Saludos, -------------- Atte.: Daniel Rodríguez Ciudad de México: (55) 5018 0565 WhatsApp: +52 33 1607 2089 Si no deseas recibir más correos, haz clic aquí para darte de baja.

[merged mm-hotfixes-stable] mm-prevent-poison-consumption-when-splitting-thp.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: prevent poison consumption when splitting THP has been removed from the -mm tree. Its filename was mm-prevent-poison-consumption-when-splitting-thp.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Qiuxu Zhuo <qiuxu.zhuo(a)intel.com> Subject: mm: prevent poison consumption when splitting THP Date: Sat, 11 Oct 2025 15:55:19 +0800 When performing memory error injection on a THP (Transparent Huge Page) mapped to userspace on an x86 server, the kernel panics with the following trace. The expected behavior is to terminate the affected process instead of panicking the kernel, as the x86 Machine Check code can recover from an in-userspace #MC. mce: [Hardware Error]: CPU 0: Machine Check Exception: f Bank 3: bd80000000070134 mce: [Hardware Error]: RIP 10:<ffffffff8372f8bc> {memchr_inv+0x4c/0xf0} mce: [Hardware Error]: TSC afff7bbff88a ADDR 1d301b000 MISC 80 PPIN 1e741e77539027db mce: [Hardware Error]: PROCESSOR 0:d06d0 TIME 1758093249 SOCKET 0 APIC 0 microcode 80000320 mce: [Hardware Error]: Run the above through 'mcelog --ascii' mce: [Hardware Error]: Machine check: Data load in unrecoverable area of kernel Kernel panic - not syncing: Fatal local machine check The root cause of this panic is that handling a memory failure triggered by an in-userspace #MC necessitates splitting the THP. The splitting process employs a mechanism, implemented in try_to_map_unused_to_zeropage(), which reads the pages in the THP to identify zero-filled pages. However, reading the pages in the THP results in a second in-kernel #MC, occurring before the initial memory_failure() completes, ultimately leading to a kernel panic. See the kernel panic call trace on the two #MCs. First Machine Check occurs // [1] memory_failure() // [2] try_to_split_thp_page() split_huge_page() split_huge_page_to_list_to_order() __folio_split() // [3] remap_page() remove_migration_ptes() remove_migration_pte() try_to_map_unused_to_zeropage() // [4] memchr_inv() // [5] Second Machine Check occurs // [6] Kernel panic [1] Triggered by accessing a hardware-poisoned THP in userspace, which is typically recoverable by terminating the affected process. [2] Call folio_set_has_hwpoisoned() before try_to_split_thp_page(). [3] Pass the RMP_USE_SHARED_ZEROPAGE remap flag to remap_page(). [4] Try to map the unused THP to zeropage. [5] Re-access pages in the hw-poisoned THP in the kernel. [6] Triggered in-kernel, leading to a panic kernel. In Step[2], memory_failure() sets the poisoned flag on the page in the THP by TestSetPageHWPoison() before calling try_to_split_thp_page(). As suggested by David Hildenbrand, fix this panic by not accessing to the poisoned page in the THP during zeropage identification, while continuing to scan unaffected pages in the THP for possible zeropage mapping. This prevents a second in-kernel #MC that would cause kernel panic in Step[4]. Thanks to Andrew Zaborowski for his initial work on fixing this issue.
