Re: [PATCH] mptcp: correct MPTCP_SUBFLOW_ATTR_SSN_OFFSET reserved size

Hi Eugene,

ssn_offset field is u32 and is placed into the netlink response with
nla_put_u32(), but only 2 bytes are reserved for the attribute payload
in subflow_get_info_size() (even though it makes no difference in the end,
as it is aligned up to 4 bytes).  Supply the correct argument to the relevant
nla_total_size() call to make it less confusing.

Good catch, thank you for sharing this patch!

The modification in the code and the description look good to me!


Please note that when you submit a patch to the Netdev mailing list, the
subject should have the 'PATCH net' prefix (or net-next) as mentioned in
the Netdev doc:

  https://docs.kernel.org/process/maintainer-netdev.html

Fixes: 5147dfb5083204d6 ("mptcp: allow dumping subflow context to userspace")

Checkpatch is complaining about this line, because the commit ID should
have 12 chars:


https://docs.kernel.org/process/submitting-patches.html#describe-your-changes

Note that checkpatch.pl also points out the fact that the lines in the
commit description should have max 75 chars -- ideally 72 -- which is
not the case above with the line ending with 'relevant'.

Do you mind sending a v2 with these small fixes, so your patch can be
directly applied in the net tree, please?

(Do not forget to wait 24h between two versions as mentioned in the doc)

Cheers,
Matt
