2015-04-21perf hists browser: Change print format from %lu to %PRIu64Tom Huynh
The nr_events variable in tools/perf/ui/browsers/hists.c is of type u64, so the print format (%lu) causes 'perf report' to show 0 event count when running with 32-bit userspace without redirection. This patch fixes that problem by printing nr_events as PRIu64.

PMCs on PowerPC increases towards 0x80000000 and triggers an overflow interrupt when the msb is set to collect a sample. Therefore, to setup for the next sample collection, pmu_start should set the pmc value to 0x80000000 - left instead of left which incorrectly delays the next overflow interrupt.

This patch adds support for MACsec in DPAA. The feature is implemented as a separate driver and hooks into the DPAA Ethernet driver using the hooks exported by the latter. The MACsec driver exposes a set of APIs allowing the user to configure the hardware in MACsec mode and to change configuration at runtime (add/ remove secure channels, secure associations, change secure association keys, etc.). The following capabilities are supported by the current implementation: - MACsec enabled on multiple interfaces - one SecY per interface (MAC) - one TX Secure Channel per SecY - up to 16 RX Secure Channels per SecY - debugfs statistics (TX counters only) per CPU per interface Signed-off-by: Camelia Groza <camelia.groza@freescale.com> Signed-off-by: Andrei Vasiliu <andrei.vasiliu@freescale.com> Signed-off-by: Iulia Manda <manda.iulia@freescale.com> Signed-off-by: Cristian Sovaiala <cristian.sovaiala@freescale.com> Change-Id: I8fe2883a716bf82dc14aae467f3e0eab140d236d Reviewed-on: http://git.am.freescale.net:8181/33832 Reviewed-by: Madalin-Cristian Bucur <madalin.bucur@freescale.com> Tested-by: Madalin-Cristian Bucur <madalin.bucur@freescale.com>

2015-03-30powerpc: Don't force ENOSYS as error on syscall failBogdan Purcareata
In certain scenarios - e.g. seccomp filtering with ERRNO as default action - the system call fails for other reasons than the syscall not being available. The seccomp filter can be configured to store a user-defined error code on return from a blacklisted syscall. Don't always set ENOSYS on do_syscall_trace_enter failure. Delegate setting ENOSYS in case of failure, where appropriate, to do_syscall_trace_enter. v4: - update syscall_exit to be local label on 64bit, after rebasing on top of 3.19 v3: - keep setting ENOSYS in the syscall entry assembly for scenarios without syscall tracing v2: - move setting ENOSYS as errno from the syscall entry assembly to do_syscall_trace_enter, only in the specific case Upstream-Status: Pending [https://lkml.org/lkml/2015/2/18/50] Signed-off-by: Bogdan Purcareata <bogdan.purcareata@freescale.com> Change-Id: I938a8754407a60c79fe9485cc76a6ec891e08e82 Reviewed-on: http://git.am.freescale.net:8181/33030 Reviewed-by: Scott Wood <scottwood@freescale.com> Tested-by: Honghua Yin <Hong-Hua.Yin@freescale.com> Reviewed-by: Honghua Yin <Hong-Hua.Yin@freescale.com>

2015-03-30seccomp,x86,arm,mips,s390: Remove nr parameter from secure_computingBogdan Purcareata
The secure_computing function took a syscall number parameter, but it only paid any attention to that parameter if seccomp mode 1 was enabled. Rather than coming up with a kludge to get the parameter to work in mode 2, just remove the parameter. To avoid churn in arches that don't have seccomp filters (and may not even support syscall_get_nr right now), this leaves the parameter in secure_computing_strict, which is now a real function. For ARM, this is a bit ugly due to the fact that ARM conditionally supports seccomp filters. Fixing that would probably only be a couple of lines of code, but it should be coordinated with the audit maintainers. This will be a slight slowdown on some arches. The right fix is to pass in all of seccomp_data instead of trying to make just the syscall nr part be fast. This is a prerequisite for making two-phase seccomp work cleanly.

2015-03-30powerpc/kernel: Make syscall_exit a local labelBogdan Purcareata
Currently when we back trace something that is in a syscall we see something like this: [c000000000000000] [c000000000000000] SyS_read+0x6c/0x110 [c000000000000000] [c000000000000000] syscall_exit+0x0/0x98 Although it's entirely correct, seeing syscall_exit at the bottom can be confusing - we were exiting from a syscall and then called SyS_read() ? If we instead change syscall_exit to be a local label we get something more intuitive: [c0000001fa46fde0] [c00000000026719c] SyS_read+0x6c/0x110 [c0000001fa46fe30] [c000000000009264] system_call+0x38/0xd0 ie. we were handling a system call, and it was SyS_read().

2015-03-30powerpc: Fix sys_call_table declaration to enable syscall tracingRomeo Cane
Declaring sys_call_table as a pointer causes the compiler to generate the wrong lookup code in arch_syscall_addr(). <arch_syscall_addr>: lis r9,-16384 rlwinm r3,r3,2,0,29 - lwz r11,30640(r9) - lwzx r3,r11,r3 + addi r9,r9,30640 + lwzx r3,r9,r3 blr The actual sys_call_table symbol, declared in assembler, is an array. If we lie about that to the compiler we get the wrong code generated, as above. This definition seems only to be used by the syscall tracing code in kernel/trace/trace_syscalls.c. With this patch I can successfully use the syscall tracepoints: bash-3815 [002] .... 333.239082: sys_write -> 0x2 bash-3815 [002] .... 333.239087: sys_dup2(oldfd: a, newfd: 1) bash-3815 [002] .... 333.239088: sys_dup2 -> 0x1 bash-3815 [002] .... 333.239092: sys_fcntl(fd: a, cmd: 1, arg: 0) bash-3815 [002] .... 333.239093: sys_fcntl -> 0x1 bash-3815 [002] .... 333.239094: sys_close(fd: a) bash-3815 [002] .... 333.239094: sys_close -> 0x0 Signed-off-by: Romeo Cane <romeo.cane.ext@coriant.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> (cherry picked from commit 1028ccf560b97adbf272381a61a67e17d44d1054) Signed-off-by: Bogdan Purcareata <bogdan.purcareata@freescale.com> Change-Id: I1754c0e1ca6c77cc56566bf50019c153ea405cbf Reviewed-on: http://git.am.freescale.net:8181/33026 Reviewed-by: Scott Wood <scottwood@freescale.com> Tested-by: Honghua Yin <Hong-Hua.Yin@freescale.com> Reviewed-by: Honghua Yin <Hong-Hua.Yin@freescale.com>
