*	selftests: bpf: centre kernel bpf objects under new subdir "progs"	Jiong Wang	2019-02-11	1	-60/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	At the moment, all kernel bpf objects are listed under BPF_OBJ_FILES. Listing them manually sometimes causing patch conflict when people are adding new testcases simultaneously. It is better to centre all the related source files under a subdir "progs", then auto-generate the object file list.

*	selftests/bpf: add a test for device cgroup controller	Roman Gushchin	2017-11-05	1	-0/+60
	Add a test for device cgroup controller. The test loads a simple bpf program which logs all device access attempts using trace_printk() and forbids all operations except operations with /dev/zero and /dev/urandom. Then the test creates and joins a test cgroup, and attaches the bpf program to it. Then it tries to perform some simple device operations and checks the result: create /dev/null (should fail) create /dev/zero (should pass) copy data from /dev/urandom to /dev/zero (should pass) copy data from /dev/urandom to /dev/full (should fail) copy data from /dev/random to /dev/zero (should fail) Signed-off-by: Roman Gushchin <guro@fb.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Tejun Heo <tj@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: David S.
