Some hardware can operate in either "host" or "endpoint" mode, which means
there can be both a host bridge driver and an endpoint driver for the same
device. Those drivers share a lot of code, so sometimes they live in the
same source file.
The host bridge driver requires CONFIG_PCI=y because it enumerates PCI
devices below the bridge using the PCI core. The endpoint driver does not
require CONFIG_PCI=y because it runs in an embedded kernel on the other
side of the device, e.g., on an adapter card.
pci-dra7xx.c contains both host and endpoint drivers. If we select only
the endpoint driver (CONFIG_PCI=n and CONFIG_PCI_DRA7XX_EP=y), the unneeded
host driver is still compiled. It references pci_irqd_intx_xlate(), which
is not present when CONFIG_PCI=n, which causes this error:
drivers/pci/dwc/pci-dra7xx.c:229:11: error: 'pci_irqd_intx_xlate' undeclared here (not in a function)
Add a dummy pci_irqd_intx_xlate() for the CONFIG_PCI=n case.

e7fd37ba1217 ("cgroup: avoid copying strings longer than the buffers")
converted possibly unsafe strncpy() usages in cgroup to strscpy().
However, although the callsites are completely fine with truncated
copied, because strscpy() is marked __must_check, it led to the
following warnings.
kernel/cgroup/cgroup.c: In function ‘cgroup_file_name’:
kernel/cgroup/cgroup.c:1400:10: warning: ignoring return value of ‘strscpy’, declared with attribute warn_unused_result [-Wunused-result]
strscpy(buf, cft->name, CGROUP_FILE_NAME_MAX);
^
To avoid the warnings, 50034ed49645 ("cgroup: use strlcpy() instead of
strscpy() to avoid spurious warning") switched them to strlcpy().
strlcpy() is worse than strlcpy() because it unconditionally runs
strlen() on the source string, and the only reason we switched to
strlcpy() here was because it was lacking __must_check, which doesn't
reflect any material differences between the two function. It's just
that someone added __must_check to strscpy() and not to strlcpy().
These basic string copy operations are used in variety of ways, and
one of not-so-uncommon use cases is safely handling truncated copies,
where the caller naturally doesn't care about the return value. The
__must_check doesn't match the actual use cases and forces users to
opt for inferior variants which lack __must_check by happenstance or
spread ugly (void) casts.
Remove __must_check from strscpy() and restore strscpy() usages in
cgroup.

Adds a new page to mlx5 core containing clock info data that allows
user level applications to translate between cqe timestamp to
nanoseconds. The information stored into this page is represented
through mlx5_ib_clock_info.
In order to synchronize between kernel and user space a sequence
number is incremented at the beginning and end of each update.
An odd number means the data is being updated while an even means
the access was already done. To guarantee that the data structure
was accessed atomically user will:
repeat:
seq1 = <read sequence>
goto <repeate> while odd
<read data structure>
seq2 = <read sequence>
if seq1 != seq2 goto repeat

For host JIT, there are "jited_len"/"bpf_func" fields in struct bpf_prog
used by all host JIT targets to get jited image and it's length. While for
offload, targets are likely to have different offload mechanisms that these
info are kept in device private data fields.
Therefore, BPF_OBJ_GET_INFO_BY_FD syscall needs an unified way to get JIT
length and contents info for offload targets.
One way is to introduce new callback to parse device private data then fill
those fields in bpf_prog_info. This might be a little heavy, the other way
is to add generic fields which will be initialized by all offload targets.
This patch follow the second approach to introduce two new fields in
struct bpf_dev_offload and teach bpf_prog_get_info_by_fd about them to fill
correct jited_prog_len and jited_prog_insns in bpf_prog_info.

while working on this series, I contributed one as well.
The first two patches add support to CAN device infrastructure to limit
the bitrate of a CAN adapter if the used CAN-transceiver has a certain
maximum bitrate.
The remaining patches improve the m_can driver. They add support for
bitrate limiting to the driver, clean up the driver and add support for

Add a marker for retpoline to the module VERMAGIC. This catches the case
when a non RETPOLINE compiled module gets loaded into a retpoline kernel,
making it insecure.
It doesn't handle the case when retpoline has been runtime disabled. Even
in this case the match of the retcompile status will be enforced. This
implies that even with retpoline run time disabled all modules loaded need
to be recompiled.

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-01-17
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add initial BPF map offloading for nfp driver. Currently only
programs were supported so far w/o being able to access maps.
Offloaded programs are right now only allowed to perform map
lookups, and control path is responsible for populating the
maps. BPF core infrastructure along with nfp implementation is
provided, from Jakub.
2) Various follow-ups to Josef's BPF error injections. More
specifically that includes: properly check whether the error
injectable event is on function entry or not, remove the percpu
bpf_kprobe_override and rather compare instruction pointer
with original one, separate error-injection from kprobes since
it's not limited to it, add injectable error types in order to
specify what is the expected type of failure, and last but not
least also support the kernel's fault injection framework, all
from Masami.
3) Various misc improvements and cleanups to the libbpf Makefile.
That is, fix permissions when installing BPF header files, remove
unused variables and functions, and also install the libbpf.h
header, from Jesper.
4) When offloading to nfp JIT and the BPF insn is unsupported in the
JIT, then reject right at verification time. Also fix libbpf with
regards to ELF section name matching by properly treating the
program type as prefix. Both from Quentin.
5) Add -DPACKAGE to bpftool when including bfd.h for the disassembler.
This is needed, for example, when building libfd from source as
bpftool doesn't supply a config.h for bfd.h. Fix from Jiong.
6) xdp_convert_ctx_access() is simplified since it doesn't need to
set target size during verification, from Jesper.
7) Let bpftool properly recognize BPF_PROG_TYPE_CGROUP_DEVICE
program types, from Roman.
8) Various functions in BPF cpumap were not declared static, from Wei.
9) Fix a double semicolon in BPF samples, from Luis.

Clean up: Over time, the industry has adopted the term "frwr"
instead of "frmr". The term "frwr" is now more widely recognized.
For the past couple of years I've attempted to add new code using
"frwr" , but there still remains plenty of older code that still
uses "frmr". Replace all usage of "frmr" to avoid confusion.
While we're churning code, rename variables unhelpfully called "f"
to "frwr", to improve code clarity.

No more print_symbol()/__print_symbol() users left, remove these
symbols.
It was a very old API that encouraged people use continuous lines.
It had been obsoleted by %pS format specifier in a normal printk()
call.

Some older compilers (gcc-4.4 through 4.6 in particular) struggle
with the way that blkg_rwstat_read() returns a structure, leading
to excessive stack usage and rather inefficient code:
block/blk-cgroup.c: In function 'blkg_destroy':
block/blk-cgroup.c:354:1: error: the frame size of 1296 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
block/cfq-iosched.c: In function 'cfqg_stats_add_aux':
block/cfq-iosched.c:753:1: error: the frame size of 1928 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
block/bfq-cgroup.c: In function 'bfqg_stats_add_aux':
block/bfq-cgroup.c:299:1: error: the frame size of 1928 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
I also notice that there is no point in using atomic accesses
for the local variables, so storing the temporaries in simple 'u64'
variables not only avoids the stack usage on older compilers but
also improves the object code on modern versions.

This patch brings basic support for the Linux Driver Model to the
NuBus subsystem.
For flexibility, the matching of boards with drivers is left up to the
drivers. This is also the approach taken by NetBSD. A board may have
many functions, and drivers may have to consider many functional
resources and board resources in order to match a device.
This implementation does not bind drivers to resources (nor does it bind
many drivers to the same board). Apple's NuBus declaration ROM design
is flexible enough to allow that, but I don't see a need to support it
as we don't use the "slot zero" resources (in the main logic board ROM).
Eliminate the global nubus_boards linked list by rewriting the procfs
board iterator around bus_for_each_dev(). Hence the nubus device refcount
can be used to determine the lifespan of board objects.

It is misleading to call a functional resource a "device". In adopting
the Linux Driver Model, the struct device will be embedded in struct
nubus_board. That will compound the terminlogy problem because drivers
will bind with boards, not with functional resources. Avoid this by
renaming struct nubus_dev as struct nubus_rsrc. "Functional resource"
is the vendor's terminology so this helps avoid confusion.
