[PATCH net-next 3/3] idpf: fix undefined reference to tcp_gro_complete() when !CONFIG_INET

[PATCH net-next 3/3] idpf: fix undefined reference to tcp_gro_complete() when !CONFIG_INET
Posted by Alexander Lobakin 2 years, 4 months ago 
When CONFIG_INET is not set, tcp_gro_complete is not compiled, although
the drivers using it may still be compiled (spotted by Randy):

aarch64-linux-ld: drivers/net/ethernet/intel/idpf/idpf_txrx.o:
in function `idpf_rx_rsc.isra.0':
drivers/net/ethernet/intel/idpf/idpf_txrx.c:2909:(.text+0x40cc):
undefined reference to `tcp_gro_complete'

The drivers need to guard the calls to it manually.
Return early from the RSC completion function if !CONFIG_INET, it won't
work properly either way. This effectively makes it be compiled-out
almost entirely on such builds.

Fixes: 3a8845af66ed ("idpf: add RX splitq napi poll support")

That builds for me.  Thanks.

Tested-by: Randy Dunlap <rdunlap@infradead.org>

I hope that these patches can be merged into the v6.6 instead of
v6.7 kernel at some point (i.e., [PATCH net] instead of net-next).

Did any of the offending code make it into 6.6? I thought all of this
was from recent merges after 6.6 closed.

Even if this is just > v6.6 kernels (i.e., linux-next),
it would be very good to get a fix merged for these build errors.
I keep getting build errors in linux-next....

A standalone version for the idpf driver fix was posted at [1], and another alternative fix was posted at [2]

Fixes for the ice driver have already merged.

[1]: https://lore.kernel.org/netdev/20230921125936.1621191-1-aleksander.lobakin@intel.com/
[2]: https://lore.kernel.org/netdev/20230925155858.651425-1-arnd@kernel.org/

The fix from Arnd got approval from Olek, but it seems like it stalled out after asking about stubs. I'm fine with either approach but would  also like to see a fix merge soon.

Thanks,
Jake

The suggestion of making NET == INET is quite tempting but requires
extra consideration. Since nobody seems to have the cycles, let's
go with the stubs?

Yea. I think NET == INET would cause a bit more challenge in the
immediate term. Its possibly worth exploring but it would be nice to get
the build bots happy first.

I can take the time this morning to work on a version that implements
the stub, and post it.

I don't know what happened, Tony dropped this commit from his tree due
to that we agreed yours (which optimizes out IPv6 code if it's not
enabled) is better, then Tony asked the netdev maintainers whether it
can be taken directly, but no updates since then.
I also asked Tony why he took my patch into his tree while I wrote under
the commit message that it should've been taken directly, also no replies :D
And all that for the bug that breaks linux-next build, meh.
