Inconsistent handling of CONFIG_SYN_COOKIES breaks procps

Bug #361687 reported by Loïc Minier on 2009-04-15
Affects Status Importance Assigned to Milestone
linux (Ubuntu)
Amit Kucheria

Bug Description

SRU justification:

Impact: iop32x and versatile get an error on bot when network setup tries to enable syncookies because this is not defined on those kernels. All other kernels have this option set.

Fix: Enable CONFIG_SYN_COOKIES on those kernels.

Testcase: Network start



procps tries to set some sysctl vars on boot notably:

But it causes an error on the versatile flavor and presumably other flavors since this isn't supported.

debian/config/armel/config.iop32x:# CONFIG_SYN_COOKIES is not set
debian/config/armel/config.versatile:# CONFIG_SYN_COOKIES is not set

These configs should be set consistenly for all Ubuntu kernels.

I did not touch iop32x because of its sensitivity to kernel size.

And I didn't have the bandwidth to test on ixp4xx before release.

But I can enable it if QA can test the change.

iop32x has room for a larger kernel still. ixp4xx is correct already.
