Hi Daniel,

FYI, we noticed the below changes on

commit b58537a1f5629bdc98a8b9dc2051ce0e952f6b4b ("net: sctp: fix permissions for rto_alpha and rto_beta knobs")

There's no way this is legitimate, that commit cannot possibly affect the performance of netperf. I wouldn't bother to spend any time investigating this.

One assumption could be that netperf was setting this knob internally and ignoring the result of it (error/success), but that we might need to look up in netperf source to confirm.

Cheers,

Daniel

Confirmed netperf-2.4.5 doesn't do this.

Ok, thanks for checking, then I fully agree with you.
