ipv6: per netns FIB6 walkers and garbage collector
Commit 2ac3ac8f86 ("ipv6: prevent fib6_run_gc() contention") reduced
the risk of contention on FIB6 garbage collector lock on systems with
many CPUs. However, one of our customers can still observe heavy
contention on fib6_gc_lock which can even trigger the soft lockup
detector.
This is caused by garbage collector running in forced mode from a timer.
While there is one timer per network namespace, the instances of
fib6_run_gc() running from them are protected by one global spinlock so
that only one garbage collector can run at any moment and other
namespaces have to wait. As most relevant data structures are separated
per netns, there is little reason for garbage collectors blocking each
other.
Similar problem exists for walkers: changes in one tree do not need to
adjust (and block) walkers traversing FIB trees in other namespaces.
This series separates both the walkers infrastructure and garbage
collector so that they work independently in network namespaces.
v2: get rid of ifdef in ipv6_route_seq_setup_walk(), pass net from
callers instead
====================

One of our customers observed issues with FIB6 garbage collectors
running in different network namespaces blocking each other, resulting
in soft lockups (fib6_run_gc() initiated from timer runs always in
forced mode).
Now that FIB6 walkers are separated per namespace, there is no more need
for instances of fib6_run_gc() in different namespaces blocking each
other. There is still a call to icmp6_dst_gc() which operates on shared
data but this function is protected by its own shared lock.

Dmitry reported that sctp_add_bind_addr may read more bytes than
expected in case the parameter is a IPv4 addr supplied by the user
through calls such as sctp_bindx_add(), because it always copies
sizeof(union sctp_addr) while the buffer may be just a struct
sockaddr_in, which is smaller.
This patch then fixes it by limiting the memcpy to the min between the
union size and a (new parameter) provided addr size. Where possible this
parameter still is the size of that union, except for reading from
user-provided buffers, which then it accounts for protocol type.

The assumptions from commit 0c1d70af92 ("net: use dst_cache for vxlan

("net/ipv4: add dst cache support for gre lwtunnels") on dst_cache usage
when ip_tunnel_info is used is unfortunately not always valid as assumed.
While it seems correct for ip_tunnel_info front-ends such as OVS, eBPF
however can fill in ip_tunnel_info for consumers like vxlan, geneve or gre
with different remote dsts, tos, etc, therefore they cannot be assumed as
packet independent.
Right now vxlan, geneve, gre would cache the dst for eBPF and every packet
would reuse the same entry that was first created on the initial route
lookup. eBPF doesn't store/cache the ip_tunnel_info, so each skb may have
a different one.
Fix it by adding a flag that checks the ip_tunnel_info. Also the !tos test
in vxlan needs to be handeled differently in this context as it is currently
inferred from ip_tunnel_info as well if present. ip_tunnel_dst_cache_usable()
helper is added for the three tunnel cases, which checks if we can use dst
cache.

After eBPF being able to programmatically access/manage tunnel key meta
data via commit d3aa45ce6b ("bpf: add helpers to access tunnel metadata")
and more recently also for IPv6 through c6c3345407 ("bpf: support ipv6
for bpf_skb_{set,get}_tunnel_key"), this work adds two complementary
helpers to generically access their auxiliary tunnel options.
Geneve and vxlan support this facility. For geneve, TLVs can be pushed,
and for the vxlan case its GBP extension. I.e. setting tunnel key for geneve
case only makes sense, if we can also read/write TLVs into it. In the GBP
case, it provides the flexibility to easily map the group policy ID in
combination with other helpers or maps.
I chose to model this as two separate helpers, bpf_skb_{set,get}_tunnel_opt(),
for a couple of reasons. bpf_skb_{set,get}_tunnel_key() is already rather
complex by itself, and there may be cases for tunnel key backends where
tunnel options are not always needed. If we would have integrated this
into bpf_skb_{set,get}_tunnel_key() nevertheless, we are very limited with
remaining helper arguments, so keeping compatibility on structs in case of
passing in a flat buffer gets more cumbersome. Separating both also allows
for more flexibility and future extensibility, f.e. options could be fed
directly from a map, etc.
Moreover, change geneve's xmit path to test only for info->options_len
instead of TUNNEL_GENEVE_OPT flag. This makes it more consistent with vxlan's
xmit path and allows for avoiding to specify a protocol flag in the API on
xmit, so it can be protocol agnostic. Having info->options_len is enough
information that is needed. Tested with vxlan and geneve.

Commit 7d672345ed ("bpf: add generic bpf_csum_diff helper") added a
generic checksum diff helper that can feed bpf_l4_csum_replace() with
a target __wsum diff that is to be applied to the L4 checksum. This
facility is very flexible, can be cascaded, allows for adding, removing,
or diffing data, or for calculating the pseudo header checksum from
scratch, but it can also be reused for working with the IPv4 header
checksum.
Thus, analogous to bpf_l4_csum_replace(), add a case for header field
value of 0 to change the checksum at a given offset through a new helper
csum_replace_by_diff(). Also, in addition to that, this provides an
easy to use interface for feeding precalculated diffs f.e. coming from
a map. It nicely complements bpf_l3_csum_replace() that currently allows
only for csum updates of 2 and 4 byte diffs.

IORESOURCE_ROM_SHADOW means there is a copy of a device's option ROM in
RAM. The existence of such a copy and its location are arch-specific.
Previously the IORESOURCE_ROM_SHADOW flag was set in arch code, but the
0xC0000-0xDFFFF location was hard-coded into the PCI core.
If we're using a shadow copy in RAM, disable the ROM BAR and release the
address space it was consuming. Move the location information from the PCI
core to the arch code that sets IORESOURCE_ROM_SHADOW. Save the location
of the RAM copy in the struct resource for PCI_ROM_RESOURCE.
After this change, pci_map_rom() will call pci_assign_resource() and
pci_enable_rom() for these IORESOURCE_ROM_SHADOW resources, which we did
not do before. This is safe because:
- pci_assign_resource() will do nothing because the resource is marked
IORESOURCE_PCI_FIXED, which means we can't move it, and
- pci_enable_rom() will not turn on the ROM BAR's enable bit because the
resource is marked IORESOURCE_ROM_SHADOW, which means it is in RAM
rather than in PCI memory space.
Storing the location in the struct resource means "lspci" will show the
shadow location, not the value from the ROM BAR.

In anyway, this is a collection of lots of small fixes that slipped

All fixes are about ASoC, and the majority of changes are corrections
of the wrong access types in ALSA ctl enum items. They are mostly

Among them, only two changes have been done to ASoC core, and both of

harmless on 32bit architectures, but actually buggy on 64bit. So we
addressed all these now in a shot. The rest are various small ASoC
driver fixes.
Among them, only two changes have been done to ASoC core, and both of
them are trivial. The rest are all device-specific. So overall, they
should be safe to apply"

Merge tag 'edac_fix_for_4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp
Pull EDAC fix from Borislav Petkov:
"Last minute fix for sb_edac which fixes DIMM detection on certain Xeon
Phi configurations:
A single fix to the Xeon Phi section of sb_edac. The issue was
introduced during this merge window"
* tag 'edac_fix_for_4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp:
EDAC, sb_edac: Fix logic when computing DIMM sizes on Xeon Phi
Make use of the EXTABLE_FAULT exception table entries to write
a kernel copy routine that doesn't crash the system if it
encounters a machine check. Prime use case for this is to copy
from large arrays of non-volatile memory used as storage.
We have to use an unrolled copy loop for now because current
hardware implementations treat a machine check in "rep mov"
as fatal. When that is fixed we can simplify.
Return type is a "bool". True means that we copied OK, false means
that it didn't.
