2018-06-04perf probe: Use return of map__get() to make code more compactArnaldo Carvalho de Melo1-2/+1
The __get() idiom returns a reference count for the object passed, i.e. all functions of this type return the object passed, so take advantage of that to make the code more compact.

Currently 10us delay is too low for many tests to succeed. It needs to be increased. Also, many corked tests are expected to hit rx timeout irrespective of timeout value. - This patch sets 1000usec timeout value for corked tests because less than that causes broken-pipe error in tx thread. Also sets 1 second timeout for all other tests because less than that results in RX timeout - tests with apply=1 and higher number of iterations were taking lot of time.

2018-06-01bpf: fix uapi hole for 32 bit compat applicationsDaniel Borkmann1-0/+2
In 64 bit, we have a 4 byte hole between ifindex and netns_dev in the case of struct bpf_map_info but also struct bpf_prog_info. In net-next commit b85fab0e67b ("bpf: Add gpl_compatible flag to struct bpf_prog_info") added a bitfield into it to expose some flags related to programs. Thus, add an unnamed __u32 bitfield for both so that alignment keeps the same in both 32 and 64 bit cases, and can be naturally extended from there as in b85fab0e67b.

2018-06-01tools/power turbostat: Calculate additional node information for a packagePrarit Bhargava1-4/+61
The code currently assumes each package has exactly one node. This is not the case for AMD systems and Intel systems with COD. AMD systems also may re-enumerate each node's core IDs starting at 0 (for example, an AMD processor may have two nodes, each with core IDs from 0 to 7). In order to properly enumerate the cores we need to track both the physical and logical node IDs. Add physical_node_id to track the node ID assigned by the kernel, and logical_node_id used by turbostat to track the nodes per package ie) a 0-based count within the package.

2018-06-01tools/power turbostat: Fix node and siblings lookup dataLen Brown1-35/+82
The turbostat code only looks at thread_siblings_list to determine if processing units/threads are on the same the core. This works well on Intel systems which have a shared L1 instruction and data cache. This does not work on AMD systems which have shared L1 instruction cache but separate L1 data caches. Other utilities also check sibling's core ID to determine if the processing unit shares the same core. Additionally, the cpu_topology *cpus list used in topology_probe() can be used elsewhere in the code to simplify things. Export *cpus to the entire turbostat code, and add Processing Unit/Thread IDs information to each cpu_topology struct. Confirm that the thread is on the same core as indicated by thread_siblings_list. [v2]: Fixup CPU_* usage that caused gcc malloc error.

2018-06-01tools/power turbostat: set max_num_cpus equal to the cpumask lengthPrarit Bhargava1-5/+16
Future fixes will use sysfs files that contain cpumask output. The code needs to know the length of the cpumask in order to determine which cpus are set in a cpumask. Currently topo.max_cpu_num is the maximum cpu number. It can be increased the the maximum value of cpus represented in cpumasks. Set max_num_cpus to the length of a cpumask.

2018-06-01perf trace beauty prctl: Default header_dir to cwd to work without parmsArnaldo Carvalho de Melo1-1/+1
Useful when checking the effects of header synchs for the files it uses as a input to generate string tables, in retrospect this is how it should've been done from day 1, not requiring the header_dir to be set on the Makefile, will change everything later, so that the only parm, common to all generators will be $(srctree) and $(beauty_outdir). So, to see what it generates, just call it without any parameters: $ tools/perf/trace/beauty/prctl_option.sh static const char *prctl_options[] = { [1] = "SET_PDEATHSIG", [2] = "GET_PDEATHSIG", [3] = "GET_DUMPABLE", [4] = "SET_DUMPABLE", [5] = "GET_UNALIGN", [6] = "SET_UNALIGN", [7] = "GET_KEEPCAPS", [8] = "SET_KEEPCAPS", [9] = "GET_FPEMU", [10] = "SET_FPEMU", [11] = "GET_FPEXC", [12] = "SET_FPEXC", [13] = "GET_TIMING", [14] = "SET_TIMING", [15] = "SET_NAME", [16] = "GET_NAME", [19] = "GET_ENDIAN", [20] = "SET_ENDIAN", [21] = "GET_SECCOMP", [22] = "SET_SECCOMP", [25] = "GET_TSC", [26] = "SET_TSC", [27] = "GET_SECUREBITS", [28] = "SET_SECUREBITS", [29] = "SET_TIMERSLACK", [30] = "GET_TIMERSLACK", [35] = "SET_MM", [36] = "SET_CHILD_SUBREAPER", [37] = "GET_CHILD_SUBREAPER", [38] = "SET_NO_NEW_PRIVS", [39] = "GET_NO_NEW_PRIVS", [40] = "GET_TID_ADDRESS", [41] = "SET_THP_DISABLE", [42] = "GET_THP_DISABLE", [45] = "SET_FP_MODE", [46] = "GET_FP_MODE", }; static const char *prctl_set_mm_options[] = { [1] = "START_CODE", [2] = "END_CODE", [3] = "START_DATA", [4] = "END_DATA", [5] = "START_STACK", [6] = "START_BRK", [7] = "BRK", [8] = "ARG_START", [9] = "ARG_END", [10] = "ENV_START", [11] = "ENV_END", [12] = "AUXV", [13] = "EXE_FILE", [14] = "MAP", [15] = "MAP_SIZE", }; $ Cc: Adrian Hunter <[email protected]> Cc: David Ahern <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Wang Nan <[email protected]> Link: https://lkml.kernel.org/n/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2018-06-01selftests: forwarding: mirror_gre_bridge_1d_vlan: Add STP testPetr Machata1-0/+12
To test offloading of mirror-to-gretap in mlxsw for cases that a VLAN-unaware bridge is in underlay packet path, test that the STP status of bridge egress port is reflected. Signed-off-by: Petr Machata <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-06-01selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more testsPetr Machata1-0/+129
Offloading of mirror-to-gretap in mlxsw is tricky especially in cases when the gretap underlay involves bridges. Add more tests that exercise the bridge handling code: - forbidden_egress tests that check vlan removal on bridge port in the underlay packet path - untagged_egress tests that similarly check "egress untagged" - fdb_roaming tests that check whether learning FDB on a different port is reflected - stp tests for handling port STP status of bridge egress port Signed-off-by: Petr Machata <[email protected]> Signed-off-by: David S.
