-Subject: [PATCH] net: gro: parse ipv6 ext headers without frag0 invalidation
-
-The existing code always pulls the IPv6 header and sets the transport
-offset initially. Then optionally again pulls any extension headers in
-ipv6_gso_pull_exthdrs and sets the transport offset again on return from
-that call. skb->data is set at the start of the first extension header
-before calling ipv6_gso_pull_exthdrs, and must disable the frag0
-optimization because that function uses pskb_may_pull/pskb_pull instead of
-skb_gro_ helpers. It sets the GRO offset to the TCP header with
-skb_gro_pull and sets the transport header. Then returns skb->data to its
-position before this block.
-
-This commit introduces a new helper function - ipv6_gro_pull_exthdrs -
-which is used in ipv6_gro_receive to pull ipv6 ext headers instead of
-ipv6_gso_pull_exthdrs. Thus, there is no modification of skb->data, all
-operations use skb_gro_* helpers, and the frag0 fast path can be taken for
-IPv6 packets with ext headers.

-Subject: [PATCH] net: gro: fix udp bad offset in socket lookup by adding
- {inner_}network_offset to napi_gro_cb
-
-Commits a602456 ("udp: Add GRO functions to UDP socket") and 57c67ff ("udp:
-additional GRO support") introduce incorrect usage of {ip,ipv6}_hdr in the
-complete phase of gro. The functions always return skb->network_header,
-which in the case of encapsulated packets at the gro complete phase, is
-always set to the innermost L3 of the packet. That means that calling
-{ip,ipv6}_hdr for skbs which completed the GRO receive phase (both in
-gro_list and *_gro_complete) when parsing an encapsulated packet's _outer_
-L3/L4 may return an unexpected value.
-
-This incorrect usage leads to a bug in GRO's UDP socket lookup.
-udp{4,6}_lib_lookup_skb functions use ip_hdr/ipv6_hdr respectively. These
-*_hdr functions return network_header which will point to the innermost L3,
-resulting in the wrong offset being used in __udp{4,6}_lib_lookup with
-encapsulated packets.
-
-This patch adds network_offset and inner_network_offset to napi_gro_cb, and
-makes sure both are set correctly.
-
-To fix the issue, network_offsets union is used inside napi_gro_cb, in
-which both the outer and the inner network offsets are saved.
-
-Reproduction example:
-
-Endpoint configuration example (fou + local address bind)
-
- # ip fou add port 6666 ipproto 4
- # ip link add name tun1 type ipip remote 2.2.2.1 local 2.2.2.2 encap fou encap-dport 5555 encap-sport 6666 mode ipip
- # ip link set tun1 up
- # ip a add 1.1.1.2/24 dev tun1

-Subject: [PATCH] nvmem: add explicit config option to read old syntax fixed OF
- cells
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Binding for fixed NVMEM cells defined directly as NVMEM device subnodes
-has been deprecated. It has been replaced by the "fixed-layout" NVMEM
-layout binding.
-
-New syntax is meant to be clearer and should help avoiding imprecise
-bindings.
-
-NVMEM subsystem already supports the new binding. It should be a good
-idea to limit support for old syntax to existing drivers that actually
-support & use it (we can't break backward compatibility!). That way we
-additionally encourage new bindings & drivers to ignore deprecated
-binding.
-
-It wasn't clear (to me) if rtc and w1 code actually uses old syntax
-fixed cells. I enabled them to don't risk any breakage.

-Subject: [PATCH] mtd: don't look for OTP legacy NVMEM cells if proper node
- doesn't exist
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If node with "user-otp" / "factory-otp" compatible doesn't exist it's
-important to prevent NVMEM core from looking for legacy NVMEM cells.
-Otherwise it would look for them in the device node.
-
-This fixes treating NAND controller attached chips as NVMEM cell.
-Problem example:
-[ 0.410107] nand: device found, Manufacturer ID: 0xc2, Chip ID: 0xdc
-[ 0.416531] nand: Macronix MX30LF4G18AC
-[ 0.420409] nand: 512 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64
-[ 0.428022] iproc_nand 18028000.nand-controller: detected 512MiB total, 128KiB blocks, 2KiB pages, 16B OOB, 8-bit, BCH-8
-[ 0.438991] Scanning device for bad blocks
-(...)
-[ 2.848418] nvmem user-otp1: nvmem: invalid reg on /nand-controller@18028000/nand@0
-[ 2.856126] iproc_nand 18028000.nand-controller: error -EINVAL: Failed to register OTP NVMEM device
-
-This long standing issue was exposed by the support for Macronix OTP.
-
-Reported-by: Christian Marangi <ansuelsmth@gmail.com>
-Fixes: 4b361cfa8624 ("mtd: core: add OTP nvmem provider support")
-Fixes: e87161321a40 ("mtd: rawnand: macronix: OTP access for MX30LFxG18AC")

-
-Drop the flow-hash of the skb when forwarding to the L2TP netdev.
-
-This avoids the L2TP qdisc from using the flow-hash from the outer
-packet, which is identical for every flow within the tunnel.
-
-This does not affect every platform but is specific for the ethernet
-driver. It depends on the platform including L4 information in the
-flow-hash.
