[PATCH v1 OLK-6.6 0/3] kworker: Fix the problem of ipsan performance degradation on ARM architecture
by jiangdongxu 29 Feb '24

29 Feb '24

From: shaodenghui <shaodenghui(a)huawei.com> When the current downstream FS tests IPSAN, it is found that the performance on ARM is much worse than that on X86, and the test data of IPSAN fluctuates greatly. After analysis, the reason is that when iscsi issues IO, the task is sent to kworker for processing by iscsi_xmitworker. The workqueue created by iscsi can automatically identify the CPU of the soft interrupt currently processed by iscsi, and automatically schedule the workqueue to the corresponding NUMA node. shaodenghui (3): iscsi: add member for NUMA aware order workqueue workqueue: implement NUMA affinity for single thread workqueue iscsi: use dynamic single thread workqueue to improve performance drivers/scsi/iscsi_tcp.c | 9 +++++++++ drivers/scsi/libiscsi.c | 17 ++++++++++++----- include/linux/workqueue.h | 1 + include/scsi/libiscsi.h | 1 + kernel/workqueue.c | 15 ++++++++++----- 5 files changed, 33 insertions(+), 10 deletions(-) -- 2.33.0

[PATCH OLK-5.10] serial: imx: fix tx statemachine deadlock

From: Paul Geurts <paul_geurts(a)live.nl> stable inclusion from stable-v5.10.209 commit 6e04a9d30509fb53ba6df5d655ed61d607a7cfda category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I93EEE CVE: CVE-2023-52456 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 78d60dae9a0c9f09aa3d6477c94047df2fe6f7b0 ] When using the serial port as RS485 port, the tx statemachine is used to control the RTS pin to drive the RS485 transceiver TX_EN pin. When the TTY port is closed in the middle of a transmission (for instance during userland application crash), imx_uart_shutdown disables the interface and disables the Transmission Complete interrupt. afer that, imx_uart_stop_tx bails on an incomplete transmission, to be retriggered by the TC interrupt. This interrupt is disabled and therefore the tx statemachine never transitions out of SEND. The statemachine is in deadlock now, and the TX_EN remains low, making the interface useless. imx_uart_stop_tx now checks for incomplete transmission AND whether TC interrupts are enabled before bailing to be retriggered. This makes sure the state machine handling is reached, and is properly set to WAIT_AFTER_SEND.
