commit 854e55ad289ef8888e7991f0ada85d5846f5afb9 upstream.
Starting with recent GCC 8 builds, objtool and perf fail to build with
the following error:../str_error_r.c: In function ‘str_error_r’:
../str_error_r.c:25:3: error: passing argument 1 to restrict-qualified parameter aliases with argument 5 [-Werror=restrict]
snprintf(buf, buflen, "INTERNAL ERROR: strerror_r(%d, %p, %zd)=%d", errnum, buf, buflen, err);The code seems harmless, but there's probably no benefit in printing the
'buf' pointer in this situation anyway, so just remove it to make GCC
happy.Reported-by: Laura Abbott

[ Upstream commit e3d91b0ca523d53158f435a3e13df7f0cb360ea2 ]
V3: More generic skipping of relo-section (suggested by Daniel)
If clang >= 4.0.1 is missing the option '-target bpf', it will cause
llc/llvm to create two ELF sections for "Exception Frames", with
section names '.eh_frame' and '.rel.eh_frame'.The BPF ELF loader library libbpf fails when loading files with these
sections. The other in-kernel BPF ELF loader in samples/bpf/bpf_load.c,
handle this gracefully. And iproute2 loader also seems to work with these
"eh" sections.The issue in libbpf is caused by bpf_object__elf_collect() skipping
some sections, and later when performing relocation it will be
pointing to a skipped section, as these sections cannot be found by
bpf_object__find_prog_by_idx() in bpf_object__collect_reloc().This is a general issue that also occurs for other sections, like
debug sections which are also skipped and can have relo section.As suggested by Daniel. To avoid keeping state about all skipped
sections, instead perform a direct qlookup in the ELF object. Lookup
the section that the relo-section points to and check if it contains
executable machine instructions (denoted by the sh_flags
SHF_EXECINSTR). Use this check to also skip irrelevant relo-sections.Note, for samples/bpf/ the '-target bpf' parameter to clang cannot be used
due to incompatibility with asm embedded headers, that some of the samples
include. This is explained in more details by Yonghong Song in bpf_devel_QA.Signed-off-by: Jesper Dangaard Brouer

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

In the initial sockmap API we provided strparser and verdict programs
using a single attach command by extending the attach API with a the
attach_bpf_fd2 field.However, if we add other programs in the future we will be adding a
field for every new possible type, attach_bpf_fd(3,4,..). This
seems a bit clumsy for an API. So lets push the programs using two
new type fields.BPF_SK_SKB_STREAM_PARSER
BPF_SK_SKB_STREAM_VERDICTThis has the advantage of having a readable name and can easily be
extended in the future.Updates to samples and sockmap included here also generalize tests
slightly to support upcoming patch for multiple map support.Signed-off-by: John Fastabend

…nux/kernel/git/acme/linux into perf/core
Pull perf/core improvements from Arnaldo Carvalho de Melo:
User visible changes:
- Beautifiers for the 'cmd' arg of several ioctl types, including:
sound, DRM, KVM, vhost virtio and perf_events.This was done by using scripts that extract the information from
the UAPI headers, generating string tables that are then used in
the 'perf trace' syscall argument ioctl beautifier.More work needed to further use it, for instance, to use the
_IOC_DIR value where it is used sanely to suppress the third
argument, to set formatters for non-pointer values and ultimately
for using eBPF + pahole-like code to collect + beautify structs in
the third arg.Using the current scheme of having tools/ copies of kernel headers
we'll make sure tooling stays working when changes are made to the
kernel ABI headers and will be notified when they get changed,
reducing the time for 'perf trace' to support new ABIs and allowing
the tools/perf/ codebase to have the definitions it needs to
build in dozens of distros/versions, as routinely tested using
containers for, at this time, 47 environments. (Arnaldo Carvalho de Melo)Infrastructure changes:
- Clarify header version warning message (Ingo Molnar)
- Sync kernel ABI headers with tooling headers (Ingo Molnar, Arnaldo Carvalho de Melo)

tools/perf/util/intel-pt-decoder/Build: || echo "Warning: Intel PT: x86 instruction decoder differs from kernel" >&2 )) || true

The buffer passed to bpf_obj_get_info_by_fd() should be initialized
to zeros. Kernel will enforce that to guarantee we can safely extend
info structures in the future.Making the bpf_obj_get_info_by_fd() call in libbpf perform the zeroing
is problematic, however, since some members of the info structures
may need to be initialized by the callers (for instance pointers
to buffers to which kernel is to dump translated and jited images).Remove the zeroing and fix up the in-tree callers before any kernel
has been released with this code.As Daniel points out this seems to be the intended operation anyway,
since commit 95b9afd3987f ("bpf: Test for bpf ID") is itself setting
the buffer pointers before calling bpf_obj_get_info_by_fd().Signed-off-by: Jakub Kicinski

Add sysfs__write_int() to ease up writing int to sysfs. New interface
is:int sysfs__write_int(const char *entry, int value);
Also, introducing filename__write_int() which is useful for new helpers
to write sysctl values.Signed-off-by: Kan Liang
