Bug 409573 – sys-kernel/openvz-sources-2.6.32.49.6 with CONFIG_SLUB - proc.c:(.text+0x43e53): undefined reference to `slab_walk_ub'

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Alexander Zubkov 2012-03-24 18:13:57 UTC]

Compiling of sys-kernel/openvz-sources-2.6.32.49.6 with SLUB enabled fails with error:
proc.c:(.text+0x43e53): undefined reference to `slab_walk_ub'
net/built-in.o: In function `ip_rt_dump_dsts':
(.text+0x40737): undefined reference to `slab_obj_walk'
net/built-in.o: In function `_ip6_rt_dump_dsts':
route.c:(.text+0xa5a61): undefined reference to `slab_obj_walk'
make: *** [.tmp_vmlinux1] Error 1

I think it fails because of unconditional call to slab_obj_walk in file net/ipv4/route.c in function ip_rt_dump_dsts.

Reproducible: Always

I can confirm this on amd64

.config? Also if it's different from upstream provided then this is unsupported configuration (take a look at einfo at the end).

Also use gcc-4.4 or hardened gcc.

Oh, and hardened gcc works here, but is not supported upstream...
