[libbpf] dd4436bb83: kernel_selftests.bpf.test_section_names.fail
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: dd4436bb838338cfda253d7f012610a73e4078fd ("libbpf: Teach bpf_object__open to guess program types")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: kernel_selftests
with following parameters:

Welcome to fdisk (util-linux 2.29.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x95f46372.
Command (m for help): Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): Partition number (1-4, default 1): First sector (2048-536870911, default 2048): Last sector, +sectors or +size{K,M,G,T,P} (2048-536870911, default 536870911):
Created a new partition 1 of type 'Linux' and of size 5 GiB.
Command (m for help): The partition table has been altered.
Calling ioctl() to re-read partition table.
