** Description changed:
[Impact]
* linux v4.15.x fails to build on newer host machine kernels (i.e. hwe /
v4.18+ )
[Fix]
* Instead of relying on a potentially incompatible host system/kernel
definitions of PF_MAX, use the one from the source tree.
* Upstream commit in v5.1-rc1-2-gdfbd199a7cfe:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=master&id=dfbd199a7cfe3e3cd8531e1353cdbd7175bfbc5e
which was cherrypicked to stable as:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.19.y&id=145f6a70bb9b422a6df5fb8b9408046151f3e4f9
+
+ Submitted to the kernel team mailing list (whilst spamming too many people in
CC) at
+ https://lists.ubuntu.com/archives/kernel-team/2019-June/101190.html
[Test Case]
* Install linux-hwe kernel, reboot, try to rebuild linux GA kernel.
[Regression Potential]
* This is a FTBFS fix only, to use matching definitions from the target
kernel at build time.
[Other Info]
* Original bug report, autopkgtest regression rebuild test case of the
bionic's linux-oracle kernel on newer host kernels:
