[PATCH OLK-6.6 0/2] kabi: restrict the KABI fix to a specific architecture and dist
by Xie XiuQi 13 Dec '24

13 Dec '24

Some distributions need to maintain and fix KABI compatibility so that drivers do not need to be recompiled during kernel upgrades. Fixing KABI compatibility is a dangerous and hacking job. Developers need to know clearly what they are doing and the risks they may face. KABI fix actions are closely related to the processor architecture. Fixes may not be appropriate for all architectures. Improper fix may cause kernel panic or unexpected error. Only for expert users, and select N by default.

[PATCH openEuler-22.03-LTS-SP1] dmaengine: idxd: Let probe fail when workqueue cannot be enabled
by Qi Xi 13 Dec '24

From: Reinette Chatre <reinette.chatre(a)intel.com> mainline inclusion from mainline-v6.2-rc5 commit b51b75f0604f17c0f6f3b6f68f1a521a5cc6b04f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IALL6O CVE: CVE-2022-48868 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The workqueue is enabled when the appropriate driver is loaded and disabled when the driver is removed. When the driver is removed it assumes that the workqueue was enabled successfully and proceeds to free allocations made during workqueue enabling. Failure during workqueue enabling does not prevent the driver from being loaded. This is because the error path within drv_enable_wq() returns success unless a second failure is encountered during the error path. By returning success it is possible to load the driver even if the workqueue cannot be enabled and allocations that do not exist are attempted to be freed during driver remove. Some examples of problematic flows: (a) idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq(): In above flow, if idxd_wq_request_irq() fails then idxd_wq_unmap_portal() is called on error exit path, but drv_enable_wq() returns 0 because idxd_wq_disable() succeeds. The driver is thus loaded successfully. idxd_dmaengine_drv_remove()->drv_disable_wq()->idxd_wq_unmap_portal() Above flow on driver unload triggers the WARN in devm_iounmap() because the device resource has already been removed during error path of drv_enable_wq(). (b) idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq(): In above flow, if idxd_wq_request_irq() fails then idxd_wq_init_percpu_ref() is never called to initialize the percpu counter, yet the driver loads successfully because drv_enable_wq() returns 0. idxd_dmaengine_drv_remove()->__idxd_wq_quiesce()->percpu_ref_kill(): Above flow on driver unload triggers a BUG when attempting to drop the initial ref of the uninitialized percpu ref: BUG: kernel NULL pointer dereference, address: 0000000000000010 Fix the drv_enable_wq() error path by returning the original error that indicates failure of workqueue enabling. This ensures that the probe fails when an error is encountered and the driver remove paths are only attempted when the workqueue was enabled successfully.

[PATCH OLK-5.10] dmaengine: idxd: Let probe fail when workqueue cannot be enabled
by Qi Xi 13 Dec '24

13 Dec '24

From: Reinette Chatre <reinette.chatre(a)intel.com> mainline inclusion from mainline-v6.2-rc5 commit b51b75f0604f17c0f6f3b6f68f1a521a5cc6b04f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IALL6O CVE: CVE-2022-48868 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The workqueue is enabled when the appropriate driver is loaded and disabled when the driver is removed. When the driver is removed it assumes that the workqueue was enabled successfully and proceeds to free allocations made during workqueue enabling. Failure during workqueue enabling does not prevent the driver from being loaded. This is because the error path within drv_enable_wq() returns success unless a second failure is encountered during the error path. By returning success it is possible to load the driver even if the workqueue cannot be enabled and allocations that do not exist are attempted to be freed during driver remove. Some examples of problematic flows: (a) idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq(): In above flow, if idxd_wq_request_irq() fails then idxd_wq_unmap_portal() is called on error exit path, but drv_enable_wq() returns 0 because idxd_wq_disable() succeeds. The driver is thus loaded successfully. idxd_dmaengine_drv_remove()->drv_disable_wq()->idxd_wq_unmap_portal() Above flow on driver unload triggers the WARN in devm_iounmap() because the device resource has already been removed during error path of drv_enable_wq(). (b) idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq(): In above flow, if idxd_wq_request_irq() fails then idxd_wq_init_percpu_ref() is never called to initialize the percpu counter, yet the driver loads successfully because drv_enable_wq() returns 0. idxd_dmaengine_drv_remove()->__idxd_wq_quiesce()->percpu_ref_kill(): Above flow on driver unload triggers a BUG when attempting to drop the initial ref of the uninitialized percpu ref: BUG: kernel NULL pointer dereference, address: 0000000000000010 Fix the drv_enable_wq() error path by returning the original error that indicates failure of workqueue enabling.

[PATCH OLK-6.6 0/2] kabi: restrict the KABI fix to a specific architecture and dist
by Xie XiuQi 13 Dec '24

13 Dec '24

Some distributions need to maintain and fix KABI compatibility so that drivers do not need to be recompiled during kernel upgrades. Fixing KABI compatibility is a dangerous and hacking job. Developers need to know clearly what they are doing and the risks they may face. KABI fix actions are closely related to the processor architecture. Fixes may not be appropriate for all architectures. Improper fix may cause kernel panic or unexpected error. Only for expert users, and select N by default.
