2018-05-30selftests/x86: Detect -no-pie availabilityFlorian Weimer
Some toolchains need -no-pie to build all tests, others do not support the -no-pie flag at all. Therefore, add another test for the availability of the flag. This amends commit 3346a6a4e5ba8c040360f753b26938cec31a4bdc ("selftests: x86: sysret_ss_attrs doesn't build on a PIE build").

2018-05-29ftrace/selftest: Fix reset_trigger() to handle triggers with filtersSteven Rostedt (VMware)
The reset_trigger() function breaks up the command by a space ' '. This is useful to ignore the '[active]' word for triggers when removing them. But if the trigger has a filter (ie. "if prio < 10") then the filter needs to be attached to the line that is written into the trigger file to remove it. But the truncation removes the filter and the triggers are not cleared properly. Before, reset_trigger() did this: # echo 'hist:keys=common_pid if prev_prio < 10' > events/sched/sched_switch/trigger # echo 'hist:keys=common_pid if next_prio < 10' >> events/sched/sched_switch/trigger # cat events/sched/sched_switch/trigger hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if prev_prio < 10 [active] hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if next_prio < 10 [active] reset_trigger() { echo '!hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048' >> events/sched/sched_switch/trigger } # cat events/sched/sched_switch/trigger hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if prev_prio < 10 [active] hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if next_prio < 10 [active] After, where it includes the filter: reset_trigger() { echo '!hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if prev_prio < 10' >> events/sched/sched_switch/trigger } # cat events/sched/sched_switch/trigger hist:keys=common_pid:vals=hitcount:sort=hitcount:size=2048 if next_prio < 10 [active] Fixes: cfa0963dc474f ("kselftests/ftrace : Add event trigger testcases") Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Reviewed-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2018-05-29ftrace/selftest: Have the reset_trigger code be a bit more carefulSteven Rostedt (VMware)
The trigger code is picky in how it can be disabled as there may be dependencies between different events and synthetic events. Change the order on how triggers are reset. 1) Reset triggers of all synthetic events first 2) Remove triggers with actions attached to them 3) Remove all other triggers If this order isn't followed, then some triggers will not be reset, and an error may happen because a trigger is busy.

test_sock_addr was not easy to extend since it was focused on sys_bind and sys_connect quite a bit.

Recent discussions around uevent filtering (cf. net-next commit [1], [2], and [3] and discussions in [4], [5], and [6]) have shown that the semantics around uevent filtering where not well understood. Now that we have settled - at least for the moment - how uevent filtering should look like let's add some selftests to ensure we don't regress anything in the future. Note, the semantics of uevent filtering are described in detail in my commit message to [2] so I won't repeat them here.

2018-05-23selftests/bpf: Makefile fix "missing" headers on build with -idirafterSirio Balmelli
Selftests fail to build on several distros/architectures because of missing headers files. On a Ubuntu/x86_64 some missing headers are: asm/byteorder.h, asm/socket.h, asm/sockios.h On a Debian/arm32 build already fails at sys/cdefs.h In both cases, these already exist in /usr/include/<arch-specific-dir>, but Clang does not include these when using '-target bpf' flag, since it is no longer compiling against the host architecture. The solution is to: - run Clang without '-target bpf' and extract the include chain for the current system - add these to the bpf build with '-idirafter' The choice of -idirafter is to catch this error without injecting unexpected include behavior: if an arch-specific tree is built for bpf in the future, this will be correctly found by Clang.

2018-05-22selftests: fib_tests: Add option to pause after each testDavid Ahern
Add option to pause after each test before cleanup is done. Allows user to do manual inspection or more ad-hoc testing after each test with the setup in tact. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Add command line options for controlling pause on fail, controlling specific tests to run and verbose mode rather than relying on environment variables. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

S390 bpf_jit.S is removed in net-next and had changes in 'net', since that code isn't used any more take the removal. TLS data structures split the TX and RX components in 'net-next', put the new struct members from the bug fix in 'net' into the RX part. The 'net-next' tree had some reworking of how the ERSPAN code works in the GRE tunneling code, overlapping with a one-line headroom calculation fix in 'net'. Overlapping changes in __sock_map_ctx_update_elem(), keep the bits that read the prog members via READ_ONCE() into local variables before using them. Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Merge speculative store buffer bypass fixes from Thomas Gleixner: - rework of the SPEC_CTRL MSR management to accomodate the new fancy SSBD (Speculative Store Bypass Disable) bit handling. - the CPU bug and sysfs infrastructure for the exciting new Speculative Store Bypass 'feature'. - support for disabling SSB via LS_CFG MSR on AMD CPUs including Hyperthread synchronization on ZEN. - PRCTL support for dynamic runtime control of SSB - SECCOMP integration to automatically disable SSB for sandboxed processes with a filter flag for opt-out. - KVM integration to allow guests fiddling with SSBD including the new software MSR VIRT_SPEC_CTRL to handle the LS_CFG based oddities on AMD. - BPF protection against SSB .. this is just the core and x86 side, other architecture support will come separately. * 'speck-v20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (49 commits) bpf: Prevent memory disambiguation attack x86/bugs: Rename SSBD_NO to SSB_NO KVM: SVM: Implement VIRT_SPEC_CTRL support for SSBD x86/speculation, KVM: Implement support for VIRT_SPEC_CTRL/LS_CFG x86/bugs: Rework spec_ctrl base and mask logic x86/bugs: Remove x86_spec_ctrl_set() x86/bugs: Expose x86_spec_ctrl_base directly x86/bugs: Unify x86_spec_ctrl_{set_guest,restore_host} x86/speculation: Rework speculative_store_bypass_update() x86/speculation: Add virtualized speculative store bypass disable support x86/bugs, KVM: Extend speculation control for VIRT_SPEC_CTRL x86/speculation: Handle HT correctly on AMD x86/cpufeatures: Add FEATURE_ZEN x86/cpufeatures: Disentangle SSBD enumeration x86/cpufeatures: Disentangle MSR_SPEC_CTRL enumeration from IBRS x86/speculation: Use synthetic bits for IBRS/IBPB/STIBP KVM: SVM: Move spec control call after restore of GS x86/cpu: Make alternative_msr_write work for 32-bit code x86/bugs: Fix the parameters alignment and missing void x86/bugs: Make cpu_show_common() static ...
