3fce12568a kernel: modules: fix kmod-regmap redux
Jonas Gorski commented on the previous patch:
|This is actually the wrong fix and papers over an issue in one of our
|local patches.
|
|We intentionally allow regmap to be built as a module, see
|
|/target/linux/generic/hack-4.14/259-regmap_dynamic.patch
|[...]
|[The regulator code] optionally supports regmap thanks to the stubs
|provided if regmap is disabled - which breaks if you compile regmap
|as a module.

In order to mitigate this issue, this patch reverts the previous patch
and replaces the existing IS_ENABLED(CONFIG_REGMAP) with
IS_REACHABLE(CONFIG_REGMAP). This solves this particular issue as the
regulator code will now automatically fallback to the regmap stubs in
case the kmod-regmap module is enabled, but nothing else sets
CONFIG_REGMAP=y.

Note: There's still a potential issue that this patch doesn't solve:
If someone ever wants to make a OpenWrt kernel package for a
regulator module that requires the REGMAP feature for a target that
doesn't set CONFIG_REGMAP=y but has CONFIG_REGULATOR=y, the resulting
kmod-regulator-xyz package will not work on the target.
Luckily, there aren't any in-tree OpenWrt kernel module packages for
regulators at the moment. On the bright side: regmap is a critical
part nowadays and all new and upcoming architectures require it by
default. This will likely only ever be a problem for legacy targets
and devices that cannot afford to enable REGMAP.

2a598bbaa3 kernel: backport mtd support for subpartitions in DT
This is a new & warm feature that allows nesting partiitons in DT and
mixing their types (e.g. static vs. dynamic). It's very useful for
boards that have most partitions static but some of them require extra
parsing (e.g. a "firmware" partition).

It's required to successfully backport support for new devices using
that new syntax in their DT files.

Since brcm63xx has a custom alternative patch the upstream one is being
reverted for it. The plan is to make brcm63xx use the upstream
implementation.

With a10a204aab ("kernel: make ubi auto-attach check for a tar file

fdf6760cda kernel: improve ubi auto attach code readability
Move the put_mtd_device() called on multiple error conditions to a goto
label to use it later for more error conditions.

The early return on failed open of the mtd device and mismatching mtd
type allows to get rid of one level of indentation. By jumping to the
cleanup code, a refcount bug is fixed for the wrong flash type condition.

While at it, make clear that we only check for the UBI magic if the read
from flash was successful.

cf7154db07 kernel: only optimized for size if small_flash
Add a new config option to allow to select the default compile

Select the optimization for size by default if the small_flash feature is

Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.

Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.

Exceptions to the above are:

  - lantiq, where the optimization for size is only required for the
    xway_legacy subtarget but was set for the whole target
  - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
    plenty of space and an optimization for size doesn't make much sense

3698b34a00 kernel: gen_stats: Fix netlink stats dumping in the presence of padding
Backport hot off the press upstream netlink patch.  Fixes stats display
from CAKE qdisc on MIPS allowing us to bump CAKE to latest version.

The gen_stats facility will add a header for the toplevel nlattr of type
TCA_STATS2 that contains all stats added by qdisc callbacks. A reference
to this header is stored in the gnet_dump struct, and when all the
per-qdisc callbacks have finished adding their stats, the length of the
containing header will be adjusted to the right value.

However, on architectures that need padding (i.e., that don't set
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added
before the stats, which means that the stored pointer will point to the
padding, and so when the header is fixed up, the result is just a very
big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS
struct, this problem has been mostly invisible, but we exposed it with
the netlink attribute-based statistics in CAKE.

Fix the issue by fixing up the stored pointer if it points to a padding
nlattr.

65c05301c2 Re-enable arbitrary IPv6 addresses as outer ip4-in-ip6 tunnel source address
The 666-Add-support-for-MAP-E-FMRs-mesh-mode.patch kernel patches
break the possibility for using an ip4ip6 tunnel interface as a fall
back interface accepting ip4-in-ip6 tunneled packets from any remote
address. This works out of the box with any normal (non-666-patched)
kernel and can be configured by setting up an 'ip -6 tunnel' with type
'any' or 'ip4ip6' and a remote address of '::'.

The misbehavior comes with line 290 the patch which discards all packets
that do not show the expected saddr, even if no single fmr rule was
defined and despite the validity of the saddr was already approved earlier.

076d2ea682 mips: fix dynamic ftrace
The kernel patch *-mips_module_reloc.patch breaks dynamic ftrace as
dynamic ftrace depends on -mlong-calls.
See http://patchwork.linux-mips.org/patch/675/
Thus we always set -mlong-calls if the kernel is being
compiled with dynamic ftrace support.

d600de3ddd kernel: atm: pppoatm fix vc-mux connection failures
Backport a hot off the press upstream kernel ATM fix:

Preserve value of skb->truesize when accounting to vcc

"There's a hack in pskb_expand_head() to avoid adjusting skb->truesize
for certain skbs. Ideally it would cover ATM too. It doesn't. Just
stashing the accounted value and using it in atm_raw_pop() is probably
the easiest way to cope."

The issue was exposed by upstream with:

commit 14afee4b6092fde451ee17604e5f5c89da33e71e
Author: Reshetova, Elena <elena.reshetova@intel.com>
Date:   Fri Jun 30 13:08:00 2017 +0300

    net: convert sock.sk_wmem_alloc from atomic_t to refcount_t

But an earlier commit left the ticking timebomb:

158f323b9868 ("net: adjust skb->truesize in pskb_expand_head()

Sincerest thanks to Mathias Kresin <dev@kresin.me> for debugging
assistance and to David Woodhouse <dwmw2@infradead.org> for further
guidance, cajoling & patience in interpreting the debug I was giving him
and producing a fix!
