2018-11-30selftests: mlxsw: Add a test for VxLAN configuration with a VLAN-aware bridgeIdo Schimmel1-1/+203

2018-11-25selftests/powerpc: Skip test instead of failingBreno Leitao1-4/+1
Current core-pkey selftest fails if the test runs without privileges to write into the core pattern file (/proc/sys/kernel/core_pattern). This causes the test to fail and give the impression that the subsystem being tested is broken, when, in fact, the test is being executed without the proper privileges. This is the current error: test: core_pkey tags: git_version:v4.19-3-g9e3363be9bce-dirty Error writing to core_pattern file: Permission denied failure: core_pkey This patch simply skips this test if it runs without the proper privileges, avoiding this undesired failure.

2018-11-25selftests/powerpc: Allocate base registersBreno Leitao7-10/+8
Some ptrace selftests are passing input operands using a constraint that can allocate any register for the operand, and using these registers on load/store operations. If the register allocated by the compiler happens to be zero (r0), it might cause an invalid memory address access, since load and store operations consider the content of 0x0 address if the base register is r0, instead of the content of the r0 register. For example: r1 := 0xdeadbeef r0 := 0xdeadbeef ld r2, 0(1) /* will load into r2 the content of r1 address */ ld r2, 0(0) /* will load into r2 the content of 0x0 */ In order to avoid this possible problem, the inline assembly constraint should be aware that these registers will be used as a base register, thus, r0 should not be allocated. Other than that, this patch removes inline assembly operands that are not used by the tests.

2018-11-24selftests/net: add txring_overwriteWillem de Bruijn4-1/+191
Packet sockets with PACKET_TX_RING send skbs with user data in frags. Before commit 5cd8d46ea156 ("packet: copy user buffers before orphan or clone") ring slots could be released prematurely, possibly allowing a process to overwrite data still in flight. This test opens two packet sockets, one to send and one to read. The sender has a tx ring of one slot. It sends two packets with different payload, then reads both and verifies their payload. Before the above commit, both receive calls return the same data as the send calls use the same buffer. From the commit, the clone needed for looping onto a packet socket triggers an skb_copy_ubufs to create a private copy. The separate sends each arrive correctly.
