description |
This is a request to inclue a patch, submitted to the upstream linux-hyperv mailing list, in the linux-azure kernels.
Microsoft would like to request this patch in the 16.04 (4.15) and newer azure kernels. This patch fixes a prior commit, hence the SRU request:
Fixes: 415719160de3 ("Drivers: hv: vmbus: avoid scheduling in interrupt context in vmbus_initiate_unload()")
The patch specfically performs the following:
"vmbus_wait_for_unload() looks for a CHANNELMSG_UNLOAD_RESPONSE message coming from Hyper-V. But if the message isn't found for some reason, the panic path gets hung forever. Add a timeout of 10 seconds to prevent this."
The requested patch can be found at:
https://lkml.org/lkml/2020/9/13/196 |
[Impact]
This is a request to inclue a patch, submitted to the upstream linux-hyperv mailing list, in the linux-azure kernels.

https://lkml.org/lkml/2020/9/13/196
[Test Case]
Since the problem depends on a communication failure with the host. I recommend testing for regressions. The change affects when the module is removed or the system is suspended.
[Regression Potential]
The change affects the panic path and suspend so any regressions shouldn't be critical. |
