[Kernel Patch] Remove `unreachable()` in nf_nat_fullcone fix patch. #67
Closed
Locietta closed 2 months ago
Previously, I use
unreachable()
to mark unreachable branches, so clang will not complain about variables uninitialized on unreachable branches.It turns out that clang compilers will somehow emit empty basic blocks with
unreachable()
involved, which confuses objtool during the ThinLTO phase. It's very similar to https://lore.kernel.org/all/5913cdf4-9c8e-38f8-8914-d3b8a3565d73@kernel.orgobjtool gives following warning👇
So, it's better to avoid
unreachable()
and just initialize unreachable branch anyway. This fixes boot regression on my machine.Resolve #65
