Hi,
Sunil Muthuswamy <sunilmut@xxxxxxxxxxxxx> made some important fixes for
hv_sock recently. I and Sunil think it would be great to backport the
fixes to the longterm stable kernels.
Since hv_sock was firstly introduced in v4.14, we only care about
v4.14, v4.19 and v5.2.
For linux-5.2.y (currently it's v5.2.4), only one patch is missing.
The mainline commit ID is:
d5afa82c977e ("vsock: correct removal of socket from the list")
It can be cleanly cherry-picked from the mainline.
For linux-4.19.y (currently it's v4.19.62), 3 patches are missing.
The mainline commit IDs are:
cb359b604167 ("hvsock: fix epollout hang from race condition")
a9eeb998c28d ("hv_sock: Add support for delayed close")
d5afa82c977e ("vsock: correct removal of socket from the list")
They can be cleanly cherry-picked from the mainline, in the listed order here.
Note: it looks the first commit (cb359b604167) has been queued.
For linux-4.14.y (currently it's v4.14.134), 4 patches are missing.
The mainline commit IDs are:
cb359b604167 ("hvsock: fix epollout hang from race condition")
3b4477d2dcf2 ("VSOCK: use TCP state constants for sk_state")
a9eeb998c28d ("hv_sock: Add support for delayed close")
d5afa82c977e ("vsock: correct removal of socket from the list")
The third patch (a9eeb998c28d) needs small manual adjustments, and please
use the attached backported patch for it; the other 3 patches can be cleanly
cherry-picked from the mainline, in the listed order here.
Note: it looks the first commit (cb359b604167) has been queued.
Please let me know, if any clarification is needed.
Thanks!
