Xin Long 44f2e360e7 sctp: move the active_key update after sh_keys is added 
[ Upstream commit ae954bbc45 ]

In commit 58acd10092 ("sctp: update active_key for asoc when old key is
being replaced"), sctp_auth_asoc_init_active_key() is called to update
the active_key right after the old key is deleted and before the new key
is added, and it caused that the active_key could be found with the key_id.

In Ying Xu's testing, the BUG_ON in sctp_auth_asoc_init_active_key() was
triggered:

  [ ] kernel BUG at net/sctp/auth.c:416!
  [ ] RIP: 0010:sctp_auth_asoc_init_active_key.part.8+0xe7/0xf0 [sctp]
  [ ] Call Trace:
  [ ]  sctp_auth_set_key+0x16d/0x1b0 [sctp]
  [ ]  sctp_setsockopt.part.33+0x1ba9/0x2bd0 [sctp]
  [ ]  __sys_setsockopt+0xd6/0x1d0
  [ ]  __x64_sys_setsockopt+0x20/0x30
  [ ]  do_syscall_64+0x5b/0x1a0

So fix it by moving the active_key update after sh_keys is added.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
