The interrupt_mask must not be used to determine whether to signal on the host->guest ring buffer 2. The ring buffer write_index must be read (via hv_get_bytes_to_write) *after* pending_send_sz is read in order to avoid a race condition 3. Comparisons with pending_send_sz must treat the "equals" case as not-enough-space 4. Don't signal if the pending_send_sz feature is not present. Older versions of Hyper-V that don't implement this feature will poll. Fixes: 03bad714a161 ("vmbus: more host signalling avoidance") This patch is on its way upstream but has not yet been accepted into char-misc. It should apply to 4.4+ kernels that have taken 03bad714a161 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1748662/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp
