Title:
[SRU][Bionic] fix false positives in W+X checking
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
on ARM64 servers we observe call trace "arm64/mm: Found insecure W+X mapping
at address 0000000000a99000/0xa99000" while booting. These messages are a false
positive and triggered at random.
[Test]
There is no reliable way to reproduce these warnings, they are triggered at
random. But these messages can appear on any ARM64 server Cavium, Qualcomm etc.
[Fix]
Upstream fix is available in linux-next
65d313ee1a7d init: fix false positives in W+X checking
[Regression Potential]
potential for any regression is low.
