Public bug reported: This is a request to include the following two commits in 16.04 and 18.04 linux-azure:
fc96df16a1ce ("Drivers: hv: vmbus: Return -EINVAL for the sys files for unopened channels") ba50bf1ce9a5 ("Drivers: hv: vmbus: Check for ring when getting debug info") Both commits are fixes to prior commits and have been cc'd to upstream stable. Commit fc96df16a1ce is in mainline as of v4.20 Commit ba50bf1ce9a5 is in mainline as of v5.0-rc4 The problem these commits fix is that some of the code for displaying values for entries in /sys/bus/vmbus don't have appropriate locking to prevent reading an entry while it is being created or being freed. The result is accessing a bogus memory address. ** Affects: linux-azure (Ubuntu) Importance: Undecided Status: New ** Tags: kernel-hyper-v ** Tags added: kernel-hyper-v -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821378 Title: [linux-azure] Include mainline commits fc96df16a1ce and ba50bf1ce9a5 in Azure kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1821378/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
