2019-05-24tools/kvm_stat: fix fields filter for child eventsStefan Raspl2-4/+14
The fields filter would not work with child fields, as the respective parents would not be included. No parents displayed == no childs displayed. To reproduce, run on s390 (would work on other platforms, too, but would require a different filter name): - Run 'kvm_stat -d' - Press 'f' - Enter 'instruct' Notice that events like instruction_diag_44 or instruction_diag_500 are not displayed - the output remains empty. With this patch, we will filter by matching events and their parents. However, consider the following example where we filter by instruction_diag_44: kvm statistics - summary regex filter: instruction_diag_44 Event Total %Total CurAvg/s exit_instruction 276 100.0 12 instruction_diag_44 256 92.8 11 Total 276 12 Note that the parent ('exit_instruction') displays the total events, but the childs listed do not match its total (256 instead of 276). This is intended (since we're filtering all but one child), but might be confusing on first sight. Signed-off-by: Stefan Raspl <raspl@linux.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-05-24kvm: selftests: aarch64: dirty_log_test: fix unaligned memslot sizeAndrew Jones1-1/+1
The memory slot size must be aligned to the host's page size. When testing a guest with a 4k page size on a host with a 64k page size, then 3 guest pages are not host page size aligned. Since we just need a nearly arbitrary number of extra pages to ensure the memslot is not aligned to a 64 host-page boundary for this test, then we can use 16, as that's 64k aligned, but not 64 * 64k aligned.

2019-05-24KVM: selftests: do not blindly clobber registers in guest asmPaolo Bonzini1-24/+30
The guest_code of sync_regs_test is assuming that the compiler will not touch %r11 outside the asm that increments it, which is a bit brittle. Instead, we can increment a variable and use a dummy asm to ensure the increment is not optimized away. However, we also need to use a callee-save register or the compiler will insert a save/restore around the vmexit, breaking the whole idea behind the test. (Yes, "if it ain't broken...", but I would like the test to be clean before it is copied into the upcoming s390 selftests). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-05-24KVM: selftests: Fix a condition in test_hv_cpuid()Dan Carpenter1-3/+2
The code is trying to check that all the padding is zeroed out and it does this: entry->padding[0] == entry->padding[1] == entry->padding[2] == 0 Assume everything is zeroed correctly, then the first comparison is true, the next comparison is false and false is equal to zero so the overall condition is true. This bug doesn't affect run time very badly, but the code should instead just check that all three paddings are zero individually. Also the error message was copy and pasted from an earlier error and it wasn't correct.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull SPDX update from Greg KH: "Here is a series of patches that add SPDX tags to different kernel files, based on two different things: - SPDX entries are added to a bunch of files that we missed a year ago that do not have any license information at all. These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up.

2019-05-21selftests/x86: Support Atom for syscall_arg_fault testTong Bo1-2/+8
Atom-based CPUs trigger stack fault when invoke 32-bit SYSENTER instruction with invalid register values. So we also need SIGBUS handling in this case. Following is assembly when the fault exception happens. (gdb) disassemble $eip Dump of assembler code for function __kernel_vsyscall: 0xf7fd8fe0 <+0>: push %ecx 0xf7fd8fe1 <+1>: push %edx 0xf7fd8fe2 <+2>: push %ebp 0xf7fd8fe3 <+3>: mov %esp,%ebp 0xf7fd8fe5 <+5>: sysenter 0xf7fd8fe7 <+7>: int $0x80 => 0xf7fd8fe9 <+9>: pop %ebp 0xf7fd8fea <+10>: pop %edx 0xf7fd8feb <+11>: pop %ecx 0xf7fd8fec <+12>: ret End of assembler dump. According to Intel SDM, this could also be a Stack Segment Fault(#SS, 12), except a normal Page Fault(#PF, 14). Especially, in section 6.9 of Vol.3A, both stack and page faults are within the 10th(lowest priority) class, and as it said, "exceptions within each class are implementation-dependent and may vary from processor to processor". It's expected for processors like Intel Atom to trigger stack fault(SIGBUS), while we get page fault(SIGSEGV) from common Core processors.

2019-05-20ptp: Fix example program to match kernel.Richard Cochran1-84/+1
Ever since commit 3a06c7ac24f9 ("posix-clocks: Remove interval timer facility and mmap/fasync callbacks") the possibility of PHC based posix timers has been removed. In addition it will probably never make sense to implement this functionality. This patch removes the misleading example code which seems to suggest that posix timers for PHC devices will ever be a thing.

For a host which has a lower rlimit for max locked memory (e.g., 64KB), the following error occurs in one of our production systems: # /usr/sbin/bpftool prog load /paragon/pods/52877437/home/mark.o \ /sys/fs/bpf/paragon_mark_21 type cgroup/skb \ map idx 0 pinned /sys/fs/bpf/paragon_map_21 libbpf: Error in bpf_object__probe_name():Operation not permitted(1). Couldn't load basic 'r0 = 0' BPF program. Error: failed to open object file The reason is due to low locked memory during bpf_object__probe_name() which probes whether program name is supported in kernel or not during __bpf_object__open_xattr(). bpftool program load already tries to relax mlock rlimit before bpf_object__load(). Let us move set_max_rlimit() before __bpf_object__open_xattr(), which fixed the issue here.
