commit: 3908fcddc65d04e069b03be49b33fae90e424631 [11295/12552] bpf: fix lsm_cgroup build errors on esoteric configs
config: x86_64-randconfig-a016-20220718 (https://download.01.org/0day-ci/archive/20220724/202207242322.9ymWznA0-lkp@intel.com/config)
compiler: gcc-11 (Debian 11.3.0-3) 11.3.0
reproduce (this is a W=1 build):
# https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=3908fcddc65d04e069b03be49b33fae90e424631
git remote add linux-next https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
git fetch --no-tags linux-next master
git checkout 3908fcddc65d04e069b03be49b33fae90e424631
# save the config file
mkdir build_dir && cp config build_dir/.config
make W=1 O=build_dir ARCH=x86_64 SHELL=/bin/bash
If you fix the issue, kindly add following tag where applicable
Reported-by: kernel test robot <lkp@intel.com>
Note: the linux-next/master HEAD 18c107a1f120d095404d141dfad8f594bdc44020 builds fine.
It may have been fixed somewhere.
All errors (new ones prefixed by >>):

Hm, looks like [1] is not enough? I'll take another look..

With the config above:
$ git checkout 3908fcddc65d04e069b03be49b33fae90e424631
$ make
ld: vmlinux.o: in function `cgroup_bpf_release':
cgroup.c:(.text+0x22e8bf): undefined reference to
`bpf_trampoline_unlink_cgroup_shim'
ld: cgroup.c:(.text+0x22e90e): undefined reference to
`bpf_trampoline_unlink_cgroup_shim'
ld: vmlinux.o: in function `__cgroup_bpf_attach':
cgroup.c:(.text+0x22f164): undefined reference to
`bpf_trampoline_link_cgroup_shim'
ld: cgroup.c:(.text+0x22f1a5): undefined reference to
`bpf_trampoline_unlink_cgroup_shim'
ld: cgroup.c:(.text+0x22f1d9): undefined reference to
`bpf_trampoline_unlink_cgroup_shim'
ld: vmlinux.o: in function `__cgroup_bpf_detach':
cgroup.c:(.text+0x22f734): undefined reference to
`bpf_trampoline_unlink_cgroup_shim'
ld: vmlinux.o: in function `bpf_cgroup_link_release':
cgroup.c:(.text+0x22f81f): undefined reference to
`bpf_trampoline_unlink_cgroup_shim'
make: *** [Makefile:1164: vmlinux] Error 1
$ git checkout bpf-next
$ make olddefconfig
$ make
$
So seems fine? I'm assuming this failure is from the old next-20220722
and the latest linux-next is ok.
