According to the comment in the iputils code: --- /* Sigh, IP_RECVERR for raw socket * was broken until 2.4.9. So, we ignore * the first error and warn on the second. */ if (once++ == 1) fprintf(stderr, "\rWARNING: kernel is not very fresh, upgrade is recommended.\n"); ---- When I first saw the error I wondered how fresh my kernel had to be to pass iputils' tests, since I'm running on: Ishtar:packages/build/iputils-s20121221> uname -a Linux Ishtar 4.1.0-Isht-Van #2 SMP PREEMPT Tue Jun 23 07:52:09 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux So I looked at code Um... why is iputils thinking that 4.1.0 < 2.4.9 -- or that 4.1.0 is older than 2.4.9? I humbly submit that 4.1.0, released in 2015 is unquestionably 'fresher' than the date on iputils of 2012. Does this mean the check in iputils is faulty w/r/t new kernels, or do new kernels have a *SERIOUS* regression? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
