[PATCH OLK-6.6 0/1] sched: migtate user interface from smart grid to sched bpf
by Liao Chen 07 Feb '24

Migtating user interface from smart grid to sched bpf, which allows users to set SCHED_GRID_QOS_TASK_LEVEL through: /proc/${pid}/task/${pid}/tag interface. Although arbitrary integer value could be assigned to <tag>, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL to 0-7, which maintains consistency.

Migtating user interface from smart grid to sched bpf, which allows users to set SCHED_GRID_QOS_TASK_LEVEL through: /proc/${pid}/task/${pid}/tag interface. Although arbitrary integer value could be assigned to <tag>, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL to 0-7, which maintains consistency.

[PATCH openEuler-1.0-LTS] xen-netback: don't produce zero-size SKB frags
by Ziyang Xuan 06 Feb '24

06 Feb '24

From: Jan Beulich <jbeulich(a)suse.com> stable inclusion from stable-v5.10.209 commit 5bb8270789c88c0e4ad78c0de2f274f2275c7f6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YCSC CVE: CVE-2023-46838 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c7ec4f2d684e17d69bbdd7c4324db0ef5daac26a upstream. While frontends may submit zero-size requests (wasting a precious slot), core networking code as of at least 3ece782693c4b ("sock: skb_copy_ubufs support for compound pages") can't deal with SKBs when they have all zero-size fragments. Respond to empty requests right when populating fragments; all further processing is fragment based and hence won't encounter these empty requests anymore. In a way this should have been that way from the beginning: When no data is to be transferred for a particular request, there's not even a point in validating the respective grant ref. That's no different from e.g. passing NULL into memcpy() when at the same time the size is 0. This is XSA-448 / CVE-2023-46838.

Migtating user interface from smart grid to sched bpf, which allows users to set SCHED_GRID_QOS_TASK_LEVEL through: /proc/${pid}/task/${pid}/tag interface. Although arbitrary integer value could be assigned to <tag>, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL to 0-7, which maintains consistency.
