[PATCH OLK-5.10] serial: imx: fix tx statemachine deadlock
by felix 29 Feb '24

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.

[PATCH openEuler-22.03-LTS-SP2 v2] gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump
by Baokun Li 28 Feb '24

28 Feb '24

From: Osama Muhammad <osmtendev(a)gmail.com> stable inclusion from stable-v5.10.209 commit 5c28478af371a1c3fdb570ca67f110e1ae60fc37 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I932W3 CVE: CVE-2023-52448 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 8877243beafa7c6bfc42022cbfdf9e39b25bd4fa ] Syzkaller has reported a NULL pointer dereference when accessing rgd->rd_rgl in gfs2_rgrp_dump(). This can happen when creating rgd->rd_gl fails in read_rindex_entry(). Add a NULL pointer check in gfs2_rgrp_dump() to prevent that.
