Similar to IPv4, when the carrier of a netdev changes we should toggle
the 'linkdown' flag on all the nexthops using it as their nexthop
device.
This will later allow us to test for the presence of this flag during
route lookup and dump.
Up until commit 4832c30d5458 ("net: ipv6: put host and anycast routes on
device with address") host and anycast routes used the loopback netdev
as their nexthop device and thus were not marked with the 'linkdown'
flag. The patch preserves this behavior and allows one to ping the local
address even when the nexthop device does not have a carrier and the
'ignore_routes_with_linkdown' sysctl is set.

To make IPv6 more in line with IPv4 we need to be able to respond
differently to different netdev events. For example, when a netdev is
unregistered all the routes using it as their nexthop device should be
flushed, whereas when the netdev's carrier changes only the 'linkdown'
flag should be toggled.
Currently, this is not possible, as the function that traverses the
routing tables is not aware of the triggering event.
Propagate the triggering event down, so that it could be used in later
patches.

====================
pull-request: bpf-next 2018-01-07
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add a start of a framework for extending struct xdp_buff without
having the overhead of populating every data at runtime. Idea
is to have a new per-queue struct xdp_rxq_info that holds read
mostly data (currently that is, queue number and a pointer to
the corresponding netdev) which is set up during rxqueue config
time. When a XDP program is invoked, struct xdp_buff holds a
pointer to struct xdp_rxq_info that the BPF program can then
walk. The user facing BPF program that uses struct xdp_md for
context can use these members directly, and the verifier rewrites
context access transparently by walking the xdp_rxq_info and
net_device pointers to load the data, from Jesper.
2) Redo the reporting of offload device information to user space
such that it works in combination with network namespaces. The
latter is reported through a device/inode tuple as similarly
done in other subsystems as well (e.g. perf) in order to identify
the namespace. For this to work, ns_get_path() has been generalized
such that the namespace can be retrieved not only from a specific
task (perf case), but also from a callback where we deduce the
netns (ns_common) from a netdevice. bpftool support using the new
uapi info and extensive test cases for test_offload.py in BPF
selftests have been added as well, from Jakub.
3) Add two bpftool improvements: i) properly report the bpftool
version such that it corresponds to the version from the kernel
source tree. So pick the right linux/version.h from the source
tree instead of the installed one. ii) fix bpftool and also
bpf_jit_disasm build with bintutils >= 2.9. The reason for the
build breakage is that binutils library changed the function
signature to select the disassembler. Given this is needed in
multiple tools, add a proper feature detection to the
tools/build/features infrastructure, from Roman.
4) Implement the BPF syscall command BPF_MAP_GET_NEXT_KEY for the
stacktrace map. It is currently unimplemented, but there are
use cases where user space needs to walk all stacktrace map
entries e.g. for dumping or deleting map entries w/o having to
close and recreate the map. Add BPF selftests along with it,
from Yonghong.
5) Few follow-up cleanups for the bpftool cgroup code: i) rename
the cgroup 'list' command into 'show' as we have it for other
subcommands as well, ii) then alias the 'show' command such that
'list' is accepted which is also common practice in iproute2,
and iii) remove couple of newlines from error messages using
p_err(), from Jakub.
6) Two follow-up cleanups to sockmap code: i) remove the unused
bpf_compute_data_end_sk_skb() function and ii) only build the
sockmap infrastructure when CONFIG_INET is enabled since it's
only aware of TCP sockets at this time, from John.

Many kernel drivers contain code that allocates and frees both a
scatterlist and the pages that populate that scatterlist.
Introduce functions in lib/scatterlist.c that perform these tasks
instead of duplicating this functionality in multiple drivers.
Only include these functions in the build if CONFIG_SGL_ALLOC=y
to avoid that the kernel size increases if this functionality is
not used.

The driver code qede_free_fp_array() depend on kfree() can be called
with a NULL pointer. This stems from the qede_alloc_fp_array()
function which either (kz)alloc memory for fp->txq or fp->rxq.
This also simplifies error handling code in case of memory allocation
failures, but xdp_rxq_info_unreg need to know the difference.
Introduce xdp_rxq_info_is_reg() to handle if a memory allocation fails
and detect this is the failure path by seeing that xdp_rxq_info was
not registred yet, which first happens after successful alloaction in
qede_init_fp().
Driver hook points for xdp_rxq_info:
* reg : qede_init_fp
* unreg: qede_free_fp_array
Tested on actual hardware with samples/bpf program.
V2: Driver have no proper error path for failed XDP RX-queue info reg, as
qede_init_fp() is a void function.

This patch only introduce the core data structures and API functions.
All XDP enabled drivers must use the API before this info can used.
There is a need for XDP to know more about the RX-queue a given XDP
frames have arrived on. For both the XDP bpf-prog and kernel side.
Instead of extending xdp_buff each time new info is needed, the patch
creates a separate read-mostly struct xdp_rxq_info, that contains this
info. We stress this data/cache-line is for read-only info. This is
NOT for dynamic per packet info, use the data_meta for such use-cases.
The performance advantage is this info can be setup at RX-ring init
time, instead of updating N-members in xdp_buff. A possible (driver
level) micro optimization is that xdp_buff->rxq assignment could be
done once per XDP/NAPI loop. The extra pointer deref only happens for
program needing access to this info (thus, no slowdown to existing
use-cases).

Renesas SH7757 has 2 Fast and 2 Gigabit Ether controllers, while the
'sh_eth' driver can only reset and initialize TSU of the first controller
pair. Shimoda-san tried to solve that adding the 'needs_init' member to the
'struct sh_eth_plat_data', however the platform code still never sets this
flag. I think that we can infer this information from the 'devno' variable
(set to 'platform_device::id') and reset/init the Ether controller pair
only for an even 'devno'; therefore 'sh_eth_plat_data::needs_init' can be
removed...

Components relying only on the request_queue structure for accessing
block devices (e.g. I/O schedulers) have a limited knowledged of the
device characteristics. In particular, the device capacity cannot be
easily discovered, which for a zoned block device also result in the
inability to easily know the number of zones of the device (the zone
size is indicated by the chunk_sectors field of the queue limits).
Introduce the nr_zones field to the request_queue structure to simplify
access to this information. Also, add the bitmap seq_zone_bitmap which
indicates which zones of the device are sequential zones (write
preferred or write required) and the bitmap seq_zones_wlock which
indicates if a zone is write locked, that is, if a write request
targeting a zone was dispatched to the device. These fields are
initialized by the low level block device driver (sd.c for ZBC/ZAC
disks). They are not initialized by stacking drivers (device mappers)
handling zoned block devices (e.g. dm-linear).
Using this, I/O schedulers can introduce zone write locking to control
request dispatching to a zoned block device and avoid write request
reordering by limiting to at most a single write request per zone
outside of the scheduler at any time.

This patch adds a "can_" prefix to the "struct dev_rcv_lists" to better
reflect the meaning and improbe code readability.
The conversion is done with:
sed -i \
-e "s/struct dev_rcv_lists/struct can_dev_rcv_lists/g" \
net/can/*.[ch] include/net/netns/can.h

Reference counters should use refcount_t rather than atomic_t, since the
refcount_t implementation can prevent overflows, reducing the
exploitability of reference leak bugs. crypto_alg.cra_refcount is a
reference counter with the usual semantics, so switch it over to
refcount_t.
