2019-08-26perf augmented_raw_syscalls: Introduce helper to get the scratch spaceArnaldo Carvalho de Melo1-16/+16
We need more than the BPF stack can give us to format the raw_syscalls:sys_enter augmented tracepoint, so we use a PERCPU_ARRAY map for that, use a helper to shorten the sequence to access that area. Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2019-08-26perf augmented_raw_syscalls: Postpone tmp map lookup to after pid_filterArnaldo Carvalho de Melo1-3/+3
No sense in doing that lookup before figuring out if it will be used, i.e. if the pid is being filtered that tmp space lookup will be useless.

2019-08-26perf trace beauty ioctl: Fix off-by-one error in cmd->string tableBenjamin Peterson1-1/+1
While tracing a program that calls isatty(3), I noticed that strace reported TCGETS for the request argument of the underlying ioctl(2) syscall while perf trace reported TCSETS. strace is corrrect. The bug in perf was due to the tty ioctl beauty table starting at 0x5400 rather than 0x5401. Committer testing: Using augmented_raw_syscalls.o and settings to make 'perf trace' use strace formatting, i.e. with this in ~/.perfconfig # cat ~/.perfconfig [trace] add_events = /home/acme/git/linux/tools/perf/examples/bpf/augmented_raw_syscalls.c show_zeros = yes show_duration = no no_inherit = yes show_timestamp = no show_arg_names = no args_alignment = 40 show_prefix = yes # strace -e ioctl stty > /dev/null ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TIOCGWINSZ, 0x7fff8a9b0860) = -1 ENOTTY (Inappropriate ioctl for device) ioctl(1, TCGETS, 0x7fff8a9b0540) = -1 ENOTTY (Inappropriate ioctl for device) +++ exited with 0 +++ # Before: # perf trace -e ioctl stty > /dev/null ioctl(0, TCSETS, 0x7fff2cf79f20) = 0 ioctl(1, TIOCSWINSZ, 0x7fff2cf79f40) = -1 ENOTTY (Inappropriate ioctl for device) ioctl(1, TCSETS, 0x7fff2cf79c20) = -1 ENOTTY (Inappropriate ioctl for device) # After: # perf trace -e ioctl stty > /dev/null ioctl(0, TCGETS, 0x7ffed0763920) = 0 ioctl(1, TIOCGWINSZ, 0x7ffed0763940) = -1 ENOTTY (Inappropriate ioctl for device) ioctl(1, TCGETS, 0x7ffed0763620) = -1 ENOTTY (Inappropriate ioctl for device) # Signed-off-by: Benjamin Peterson <[email protected]> Tested-by: Arnaldo Carvalho de Melo <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Peter Zijlstra <[email protected]> Fixes: 1cc47f2d46206d67285aea0ca7e8450af571da13 ("perf trace beauty ioctl: Improve 'cmd' beautifier") Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2019-08-26selftests/powerpc: Fix and enhance TM signal context testsGustavo Romero4-84/+228
Currently TM signal context tests for GPR, FPR, VMX, and VSX registers print wrong register numbers (wrongly starting from register 0 instead of the first register in the non-volatile subset). Besides it the output when a mismatch happens is poor giving not much information about which context and which register mismatches, because it prints both contexts at the same time and not a comparison between the value that mismatches and the value expected and, moreover, it stops printing on the first mismatch, but it's important to know if there are other mismatches happening beyond the first one. For instance, this is the current output when a mismatch happens: test: tm_signal_context_chk_gpr tags: git_version:v5.2-8249-g02e970fae465-dirty Failed on 0 GPR 1 or 18446744073709551615 failure: tm_signal_context_chk_gpr test: tm_signal_context_chk_fpu tags: git_version:v5.2-8248-g09c289e3ef80 Failed on 0 FP -1 or -1 failure: tm_signal_context_chk_fpu test: tm_signal_context_chk_vmx tags: git_version:v5.2-8248-g09c289e3ef80 Failed on 0 vmx 0xfffffffffffffffefffffffdfffffffc vs 0xfffffffffffffffefffffffdfffffffc failure: tm_signal_context_chk_vmx test: tm_signal_context_chk_vsx tags: git_version:v5.2-8248-g09c289e3ef80 Failed on 0 vsx 0xfffffffffefffffffdfffffffcffffff vs 0xfffffffffefffffffdfffffffcffffff failure: tm_signal_context_chk_vsx This commit fixes the register numbers printed and enhances the error output by providing a full list of mismatching registers separated by the context (non-speculative or speculative context), for example: test: tm_signal_context_chk_gpr tags: git_version:v5.2-8249-g02e970fae465-dirty GPR14 (1st context) == 1 instead of -1 (expected) GPR15 (1st context) == 2 instead of -2 (expected) GPR14 (2nd context) == 0 instead of 18446744073709551615 (expected) GPR15 (2nd context) == 0 instead of 18446744073709551614 (expected) failure: tm_signal_context_chk_gpr test: tm_signal_context_chk_fpu tags: git_version:v5.2-8249-g02e970fae465-dirty FPR14 (1st context) == -1 instead of 1 (expected) FPR15 (1st context) == -2 instead of 2 (expected) failure: tm_signal_context_chk_fpu test: tm_signal_context_chk_vmx tags: git_version:v5.2-8249-g02e970fae465-dirty VMX20 (1st context) == 0xfffffffffffffffefffffffdfffffffc instead of 0x00000001000000020000000300000004 (expected) VMX21 (1st context) == 0xfffffffbfffffffafffffff9fffffff8 instead of 0x00000005000000060000000700000008 (expected) failure: tm_signal_context_chk_vmx test: tm_signal_context_chk_vsx tags: git_version:v5.2-8249-g02e970fae465-dirty VSX20 (1st context) == 0xfffffffffefffffffdfffffffcffffff instead of 0x00000001000000020000000300000004 (expected) VSX21 (1st context) == 0xfbfffffffafffffff9fffffff8ffffff instead of 0x00000005000000060000000700000008 (expected) failure: tm_signal_context_chk_vsx Finally, this commit adds comments to the tests in the hope that it will help people not so familiar with TM understand the tests.

Following the patch 'perf stat: Fix --no-scale', an alignment trap happens in process_counter_values() on ARMv7 platforms due to the attempt to copy non 64 bits aligned double words (pointed by 'count') via a NEON vectored instruction ('vld1' with 64 bits alignment constraint). This patch sets a 64 bits alignment constraint on 'contents[]' field in 'struct xyarray' since the 'count' pointer used above points to such a structure.

2019-08-22perf tools: Use perf_cpu_map__nr instead of cpu_map__nrJiri Olsa5-14/+9
Switch the rest of the perf code to use libperf's perf_cpu_map__nr(), which is the same as current cpu_map__nr() and remove the cpu_map__nr() function.

2019-08-22selftests/powerpc: Ignore generated filesGustavo Romero4-5/+12
Currently some binary files which are generated when tests are compiled are not ignored by git, so 'git status' catch them. For copyloops test, fix wrong binary names already in .gitignore. For ptrace, security, and stringloops tests add missing binary names to the .gitignore file.

2019-08-21Merge branch 'odp_fixes' into hmm.gitJason Gunthorpe75-185/+1048
From rdma.git Jason Gunthorpe says: ==================== This is a collection of general cleanups for ODP to clarify some of the flows around umem creation and use of the interval tree. ==================== The branch is based on v5.3-rc5 due to dependencies, and is being taken into hmm.git due to dependencies in the next patches. * odp_fixes: RDMA/mlx5: Use odp instead of mr->umem in pagefault_mr RDMA/mlx5: Use ib_umem_start instead of umem.address RDMA/core: Make invalidate_range a device operation RDMA/odp: Use kvcalloc for the dma_list and page_list RDMA/odp: Check for overflow when computing the umem_odp end RDMA/odp: Provide ib_umem_odp_release() to undo the allocs RDMA/odp: Split creating a umem_odp from ib_umem_get RDMA/odp: Make the three ways to create a umem_odp clear RMDA/odp: Consolidate umem_odp initialization RDMA/odp: Make it clearer when a umem is an implicit ODP umem RDMA/odp: Iterate over the whole rbtree directly RDMA/odp: Use the common interval tree library instead of generic RDMA/mlx5: Fix MR npages calculation for IB_ACCESS_HUGETLB Signed-off-by: Jason Gunthorpe <[email protected]>
2019-08-21selftests: mlxsw: Add a test case for devlink-trapIdo Schimmel1-0/+129
Test generic devlink-trap functionality over mlxsw. These tests are not specific to a single trap, but do not check the devlink-trap common infrastructure either. Currently, the only test case is device deletion (by reloading the driver) while packets are being trapped. Signed-off-by: Ido Schimmel <[email protected]> Signed-off-by: David S.

2019-08-21selftests: mlxsw: Add test cases for devlink-trap L2 dropsIdo Schimmel1-0/+484
Test that each supported packet trap is triggered under the right conditions and that packets are indeed dropped and not forwarded. Signed-off-by: Ido Schimmel <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2019-08-21tools: bpftool: show frozen status for mapsQuentin Monnet1-3/+27
When listing maps, read their "frozen" status from procfs, and tell if maps are frozen. As commit log for map freezing command mentions that the feature might be extended with flags (e.g. for write-only instead of read-only) in the future, use an integer and not a boolean for JSON output.
