2019-04-24selftests/bpf: expand test_tc_tunnel with SIT encapWillem de Bruijn3-5/+80
So far, all BPF tc tunnel testcases encapsulate in the same network protocol. Add an encap testcase that requires updating skb->protocol. The 6in4 tunnel encapsulates an IPv6 packet inside an IPv4 tunnel. Verify that bpf_skb_net_grow correctly updates skb->protocol to select the right protocol handler in __netif_receive_skb_core.

2019-04-22selftests: build and run gpio when output directory is the src dirShuah Khan1-0/+9
Build and run gpio when output directory is the src dir. gpio has dependency on tools/gpio and builds tools/gpio objects in the src directory in all cases making the src repo dirty even when object relocation is specified.

2019-04-22media: selftests: media_dev_allocator api testShuah Khan1-0/+85
Add a new test for Media Device Allocator API. Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. This test does a series of unbind/bind tests to make sure media device is released correctly when it is no longer is use and when the last driver releases the reference.

2019-04-19selftests: fix headers_install circular dependencyShuah Khan2-10/+80
"make kselftest" fails with "Circular Makefile.o <- prepare dependency dropped." error, when lib.mk invokes "make headers_install". Make level 0: Main make calls selftests run_tests target ... Make level n: selftests lib.mk invokes main make's headers_install The secondary level make inherits builtin-rules which will use the rule to generate Makefile.o and runs into "Circular Makefile.o <- prepare dependency dropped." error, and kselftest compile fails. Invoke headers_install target with --no-builtin-rules to avoid circular error.

ktest fails if meta characters are in GRUB_MENU, for example GRUB_MENU = 'Fedora (test)' The failure happens because the meta characters are not escaped, so the menu doesn't match in any entries in GRUB_FILE. Use quotemeta() to escape the meta characters.

2019-04-17selftests/kexec: update get_secureboot_modeMimi Zohar1-20/+66
The get_secureboot_mode() function unnecessarily requires both CONFIG_EFIVAR_FS and CONFIG_EFI_VARS to be enabled to determine if the system is booted in secure boot mode. On some systems the old EFI variable support is not enabled or, possibly, even implemented. This patch first checks the efivars filesystem for the SecureBoot and SetupMode flags, but falls back to using the old EFI variable support. The "secure_boot_file" and "setup_mode_file" couldn't be quoted due to globbing. This patch also removes the globbing.

2019-04-16libbpf: optimize barrier for XDP socket ringsMagnus Karlsson2-1/+6
The full memory barrier in the XDP socket rings on the consumer side between the load of the data and the store of the consumer ring is there to protect the store from being executed before the load of the data. If this was allowed to happen, the producer might overwrite the data field with a new entry before the consumer got the chance to read it. On x86, stores are guaranteed not to be reordered with older loads, so it does not need a full memory barrier here. A compile time barrier would be enough. This patch introdcues a new primitive in libbpf_util.h that implements a new barrier type (libbpf_smp_rwmb) hindering stores to be reordered with older loads. It is then used in the XDP socket ring access code in libbpf to improve performance. Signed-off-by: Magnus Karlsson <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]>
2019-04-16libbpf: remove dependency on barrier.h in xsk.hMagnus Karlsson2-3/+29
The use of smp_rmb() and smp_wmb() creates a Linux header dependency on barrier.h that is unnecessary in most parts. This patch implements the two small defines that are needed from barrier.h. As a bonus, the new implementations are faster than the default ones as they default to sfence and lfence for x86, while we only need a compiler barrier in our case. Just as it is when the same ring access code is compiled in the kernel.
