2022-07-14Merge branch 'seg6-fix-skb-checksum-for-srh-encapsulation-insertion'Paolo Abeni
Andrea Mayer says: ==================== seg6: fix skb checksum for SRH encapsulation/insertion The Linux kernel supports Segment Routing Header (SRH) encapsulation/insertion operations by providing the capability to: i) encapsulate a packet in an outer IPv6 header with a specified SRH; ii) insert a specified SRH directly after the IPv6 header of the packet. Note that the insertion operation is also referred to as 'injection'. The two operations are respectively supported by seg6_do_srh_encap() and seg6_do_srh_inline(), which operate on the skb associated to the packet as needed (e.g. adding the necessary headers and initializing them, while taking care to recalculate the skb checksum). seg6_do_srh_encap() and seg6_do_srh_inline() do not initialize the payload length of the IPv6 header, which is carried out by the caller functions. However, this approach causes the corruption of the skb checksum which needs to be updated only after initialization of headers is completed (thanks to Paolo Abeni for detecting this issue). The patchset fixes the skb checksum corruption by moving the IPv6 header payload length initialization from the callers of seg6_do_srh_encap() and seg6_do_srh_inline() directly into these functions. This patchset is organized as follows: - patch 1/3, seg6: fix skb checksum evaluation in SRH encapsulation/insertion; (* SRH encapsulation/insertion available since v4.10) - patch 2/3, seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps behaviors; (* SRv6 End.B6 and End.B6.Encaps behaviors available since v4.14) - patch 3/3, seg6: bpf: fix skb checksum in bpf_push_seg6_encap(); (* bpf IPv6 Segment Routing helpers available since v4.18) ==================== Link: https://lore.kernel.org/r/20220712175837.16267-1-andrea.mayer@uniroma2.it Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2022-07-14seg6: bpf: fix skb checksum in bpf_push_seg6_encap()Andrea Mayer
Both helper functions bpf_lwt_seg6_action() and bpf_lwt_push_encap() use the bpf_push_seg6_encap() to encapsulate the packet in an IPv6 with Segment Routing Header (SRH) or insert an SRH between the IPv6 header and the payload. To achieve this result, such helper functions rely on bpf_push_seg6_encap() which, in turn, leverages seg6_do_srh_{encap,inline}() to perform the required operation (i.e. encap/inline). This patch removes the initialization of the IPv6 header payload length from bpf_push_seg6_encap(), as it is now handled properly by seg6_do_srh_{encap,inline}() to prevent corruption of the skb checksum.

2022-07-14seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps behaviorsAndrea Mayer
The SRv6 End.B6 and End.B6.Encaps behaviors rely on functions seg6_do_srh_{encap,inline}() to, respectively: i) encapsulate the packet within an outer IPv6 header with the specified Segment Routing Header (SRH); ii) insert the specified SRH directly after the IPv6 header of the packet. This patch removes the initialization of the IPv6 header payload length from the input_action_end_b6{_encap}() functions, as it is now handled properly by seg6_do_srh_{encap,inline}() to avoid corruption of the skb checksum.

2022-07-14seg6: fix skb checksum evaluation in SRH encapsulation/insertionAndrea Mayer
Support for SRH encapsulation and insertion was introduced with commit 6c8702c60b88 ("ipv6: sr: add support for SRH encapsulation and injection with lwtunnels"), through the seg6_do_srh_encap() and seg6_do_srh_inline() functions, respectively. The former encapsulates the packet in an outer IPv6 header along with the SRH, while the latter inserts the SRH between the IPv6 header and the payload. Then, the headers are initialized/updated according to the operating mode (i.e., encap/inline). Finally, the skb checksum is calculated to reflect the changes applied to the headers. The IPv6 payload length ('payload_len') is not initialized within seg6_do_srh_{inline,encap}() but is deferred in seg6_do_srh(), i.e. the caller of seg6_do_srh_{inline,encap}(). However, this operation invalidates the skb checksum, since the 'payload_len' is updated only after the checksum is evaluated. To solve this issue, the initialization of the IPv6 payload length is moved from seg6_do_srh() directly into the seg6_do_srh_{inline,encap}() functions and before the skb checksum update takes place.

In this patch the only allowed dynamic VLAN protocol value is ETH_P_8021Q. - Save current VLAN protocol in per-bridge instance variable. Use the dynamic variable instead of hardcoded values in mlx5 bridge code.

2022-07-13net: phy: mxl-gpy: print firmware in human readable formMichael Walle
Now having a major and a minor number, also print the firmware in human readable form "major.minor". Still keep the 4-digit hexadecimal representation because that form is used in the firmware changelog documents. Also, drop the "release" string assuming that most common case, but make it clearer that the user is running a test version.
