[SRU Bionic/HWE-5.8 0/1] CVE-2021-38199

[Thadeu Lima de Souza Cascardo]

[Impact]

"Operators of remote NFSv4 can servers to cause a denial of service
(hanging of mounts) by arranging for those servers to be unreachable during
trunking detection."

[Backport]

There was an extra line from a different commit absent from bionic, which
required a conflict fix because of the extra line in the context.

[Test case]

No specific test case for the vulnerability was tested. However, it was
tested that an NFSv4 mount could still work on both 4.15 and 5.8 versions.

[Potential regression]

NFS mount or access could cause a hang or crash.
