[PATCH v2 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-1.0-LTS] padata: make padata_do_parallel find alternate callback CPU
by Yi Yang 13 Dec '24

13 Dec '24

From: Daniel Jordan <daniel.m.jordan(a)oracle.com> mainline inclusion from mainline-v5.4-rc1 commit e6ce0e0807e90d38a2cefa524ac253d7a85c3f2f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7RZMT CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- padata_do_parallel currently returns -EINVAL if the callback CPU isn't in the callback cpumask. pcrypt tries to prevent this situation by keeping its own callback cpumask in sync with padata's and checks that the callback CPU it passes to padata is valid. Make padata handle this instead. padata_do_parallel now takes a pointer to the callback CPU and updates it for the caller if an alternate CPU is used. Overall behavior in terms of which callback CPUs are chosen stays the same. Prepares for removal of the padata cpumask notifier in pcrypt, which will fix a lockdep complaint about nested acquisition of the CPU hotplug lock later in the series.

[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.

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.
