[PATCH] dhcpcd: fix for unexpected syscall 135 for 10.1.0 version

[PATCH] dhcpcd: fix for unexpected syscall 135 for 10.1.0 version

[Balaji Pothunoori]

Current dhcpcd (version 10.1.0) service crashes on the WiFi (wlan0)
interface with the following error:

"ps_seccomp_violation: unexpected syscall 135"

This update pulls in fix #421 for dhcpcd 10.1.0 to address this issue.

There are newer releases, which already have this patch. Any reason for
not upgrading? For example there was an AUH message from March 1st.

This doesn't follow the established standard. I doubt that it will not
trigger QA error.

Few patches are applied as OE Specific in https://git.openembedded.org/openembedded-core/tree/meta/recipes-connectivity/dhcpcd/files 
Hence, I can't perform end to end testing for upgrade, So proceeded with patch BACKPORT for 10.1.0 version.

I don't follow this. Surely you can. Upgrade the dhcpcd, refresh the
patches (or just apply the patch from AUH, I hope you've seen it),
verify the end-result, post the upgrade patch.
