Red Hat Bugzilla – Bug 555708
kABI whitelist request for Fujitsu modules
Last modified: 2011-01-13 15:59:48 EST
Description of problem:
missing symbols in white list:
Fujitsu are requesting that these symbols also be added to the 5.6 whitelist please:
Requesting BLOCKER or reason these won;t be in 5.6.
Can you please let me know which modules these are for? I suspect the answer to adding NAPI to the whitelist is "no", but I will check.
napi_gro_flush() is required by most current OEM LAN drivers (igb, ixgbe, bnx2). Without it, no fully-deatured LAN driver can be provided via DUP. Drives need to define a dummy replacement function instead, which makes me feel very uncomfortable.
Note that napi_gro_receive() is already part of the 5.5 KABI (bug #526342), so why not napi_gro_flush()?
Without these, no DUP-provided driver can offer SR-IOV functionality. That is going to be a significant restriction as soon as customers start using SR-IOV. When a bug fix requires a DUP driver (from Red Hat or a partner, doesn't matter), SR-IOV functionality is not available any more.
Thanks for the reply Martin. I'll include it in the processing of this request.
Have a devel ACK. Can I get a QA ACK please. Fujitsu will test this.
