Hi, Suren,
I read the previous discussion about fixing CVE-2020-29374 in stable 4.14 and 4.19 in https://lore.kernel.org/linux-mm/20210401181741.168763-1-surenb@google.com/
https://lore.kernel.org/linux-mm/20210401181741.168763-1-surenb@google.com/
And the results of the discussion is that you backports of 17839856fd58 for 4.14 and
4.19 kernels.
But the bug about dax and strace in the discussion has not been solved, right? I don't
find a conclusion on this issue, am I missing something? Does this problem still exist in
the stable 4.14 and 4.19 kernel?
That is my understanding after discussions with Andrea but I did not verify that myself. As Greg pointed out, the best way would be to try it out. Thanks, Suren.
As the code is all there for you, can you just test them and see for yourself?
thanks,

Thank you both for replies. I have tested it in stable 4.19 kernel and the bug is existed as expected.
Thanks, Liu Shixin
