Public bug reported: SRU Justification:
[Impact] Exclusion is being handled around arm_smccc_smc() only in the store functions. It should be implemented in the show functions also as this call might not be thread-safe. [Fix] Add mutex_lock/unlock around arm_smccc_smc calls in the show functions. [Test Case] Multiple simultaneous accesses to a sysfs entry exposed by the driver are successful. [Regression Potential] Can be considered minimum ** Affects: linux-bluefield (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933642 Title: mlx-bootctl: Fix exclusion issues around arm_smccc_smc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-bluefield/+bug/1933642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
