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

|
||||
|
||||
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.

Calling skb_copy on a SKB_GSO_FRAGLIST skb is not valid, since it returns
|
||||
an invalid linearized skb. This code only needs to change the ethernet
|
||||
header, so pskb_copy is the right function to call here.

|

|

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.
