this is a pull request for net-next/master consisting of 41 patches.
The first two patches are for the kvaser_pciefd driver: Christer Beskow
removes unnecessary code in the kvaser_pciefd_pwm_stop() function,
YueHaibing removes the unused including of <linux/version.h>.
In the next patch YueHaibing also removes the unused including of
<linux/version.h> in the f81601 driver.
In the ti_hecc driver the next 6 patches are by me and fix checkpatch

ti_hecc_mailbox_read() function.
The next 6 patches all target the xilinx_can driver. Anssi Hannula's
patch fixes a chip start failure with an invalid bus. The patch by
Venkatesh Yadav Abbarapu skips an error message in case of a deferred
probe. The 3 patches by Appana Durga Kedareswara rao fix the RX and TX
path for CAN-FD frames. Srinivas Neeli's patch fixes the bit timing
calculations for CAN-FD.
The next 12 patches are by me and several checkpatch warnings in the
af_can, raw and bcm components.
Thomas Gleixner provides a patch for the bcm, which switches the timer
to HRTIMER_MODE_SOFT and removes the hrtimer_tasklet.
Then 6 more patches by me for the gw component, which fix checkpatch

The vcan driver gets 3 patches by me, fixing checkpatch warnings.
And finally a patch by Andre Hartmann to fix typos in CAN's netlink

Conflict is between the two commits
1d4126c4e119 ("libbpf: sanitize VAR to
conservative 1-byte INT") and
b03bc6853c0e ("libbpf: convert libbpf code to

use the new btf_is_datasec() helper and the whitespace cleanup. Looks like
the following:
[...]
if (!has_datasec && btf_is_var(t)) {
/* replace VAR with INT */
t->info = BTF_INFO_ENC(BTF_KIND_INT, 0, 0);

*(int *)(t + 1) = BTF_INT_ENC(0, 0, 8);
} else if (!has_datasec && btf_is_datasec(t)) {
/* replace DATASEC with STRUCT */
[...]
The main changes are:
1) Addition of core parts of compile once - run everywhere (co-re) effort,
that is, relocation of fields offsets in libbpf as well as exposure of
kernel's own BTF via sysfs and loading through libbpf, from Andrii.
More info on co-re: http://vger.kernel.org/bpfconf2019.html#session-2
and http://vger.kernel.org/lpc-bpf2018.html#session-2
2) Enable passing input flags to the BPF flow dissector to customize parsing
and allowing it to stop early similar to the C based one, from Stanislav.
3) Add a BPF helper function that allows generating SYN cookies from XDP and
tc BPF, from Petar.
4) Add devmap hash-based map type for more flexibility in device lookup for
redirects, from Toke.
5) Improvements to XDP forwarding sample code now utilizing recently enabled

6) Add support for reporting the effective cgroup progs in bpftool, from Jakub

7) Fix reading kernel config from bpftool via /proc/config.gz, from Peter.
8) Fix AF_XDP umem pages mapping for 32 bit architectures, from Ivan.
9) Follow-up to add two more BPF loop tests for the selftest suite, from Alexei.
10) Add perf event output helper also for other skb-based program types, from Allan.
11) Fix a co-re related compilation error in selftests, from Yonghong.

can: xilinx_can: xcan_chip_start(): fix failure with invalid bus
Currently the xilinx_can xcan_chip_start() function, called from
.ndo_open() and via CAN_MODE_START (bus-off restart), waits for the SR
register to show the wanted operating state, with a 1 sec timeout.
However, that register bit will only be set once the HW has observed 11
consecutive recessive bits (BusIdle) on the bus.
If the bus will not see the 11 bits (e.g. it is stuck dominant), the
function will timeout and return an error. If this was done as part of a
scheduled restart from bus-off, the interface will stay in bus-off state
forever even if the bus recovers later.
According to M_CAN and FLEXCAN documentation they also wait for 11
consecutive recessive bits, but their drivers do not seem to wait for
that.
To make the behavior consistent, modify xilinx_can to also not wait for
the synchronization to complete.
The only way for users to know for sure that the bus has been joined
successfully is to see successfully received or transmitted frames. That
does not seem optimal, but it is consistent with other drivers and we
should have a properly working restart-ms with xilinx_can.

selftests/bpf: fix race in flow dissector tests
Since the "last_dissection" map holds only the flow keys for the most
recent packet, there is a small race in the skb-less flow dissector
tests if a new packet comes between transmitting the test packet, and
reading its keys from the map. If this happens, the test packet keys
will be overwritten and the test will fail.
Changing the "last_dissection" map to a hash map, keyed on the
source/dest port pair resolves this issue. Additionally, let's clear the
last test results from the map between tests to prevent previous test
cases from interfering with the following test cases.

btf: expose BTF info through sysfs
Make .BTF section allocated and expose its contents through sysfs.
/sys/kernel/btf directory is created to contain all the BTFs present
inside kernel. Currently there is only kernel's main BTF, represented as
/sys/kernel/btf/kernel file. Once kernel modules' BTFs are supported,
each module will expose its BTF as /sys/kernel/btf/<module-name> file.
Current approach relies on a few pieces coming together:
1. pahole is used to take almost final vmlinux image (modulo .BTF and
kallsyms) and generate .BTF section by converting DWARF info into
BTF. This section is not allocated and not mapped to any segment,
though, so is not yet accessible from inside kernel at runtime.
2. objcopy dumps .BTF contents into binary file and subsequently
convert binary file into linkable object file with automatically
generated symbols _binary__btf_kernel_bin_start and
_binary__btf_kernel_bin_end, pointing to start and end, respectively,
of BTF raw data.
3. final vmlinux image is generated by linking this object file (and
kallsyms, if necessary). sysfs_btf.c then creates
/sys/kernel/btf/kernel file and exposes embedded BTF contents through
it. This allows, e.g., libbpf and bpftool access BTF info at
well-known location, without resorting to searching for vmlinux image
on disk (location of which is not standardized and vmlinux image
might not be even available in some scenarios, e.g., inside qemu
during testing).
Alternative approach using .incbin assembler directive to embed BTF
contents directly was attempted but didn't work, because sysfs_proc.o is
not re-compiled during link-vmlinux.sh stage. This is required, though,
to update embedded BTF data (initially empty data is embedded, then
pahole generates BTF info and we need to regenerate sysfs_btf.o with
updated contents, but it's too late at that point).
If BTF couldn't be generated due to missing or too old pahole,
sysfs_btf.c handles that gracefully by detecting that
_binary__btf_kernel_bin_start (weak symbol) is 0 and not creating
/sys/kernel/btf at all.
v2->v3:
- added Documentation/ABI/testing/sysfs-kernel-btf (Greg K-H);
- created proper kobject (btf_kobj) for btf directory (Greg K-H);
- undo v2 change of reusing vmlinux, as it causes extra kallsyms pass
due to initially missing __binary__btf_kernel_bin_{start/end} symbols;
v1->v2:
- allow kallsyms stage to re-use vmlinux generated by gen_btf();
