[PATCH net 0/3] Some sockopt optlen fixes

From: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com>

Also in: linux-sctp

Hangbin Liu reported that some SCTP sockopt are allowing the user to get
the kernel to allocate really large buffers by not having a ceiling on
optlen.

This patchset address this issue (in patch 2), replace an GFP_ATOMIC
that isn't needed and avoid calculating the option size multiple times
in some setsockopt.

Marcelo Ricardo Leitner (3):
  sctp: GFP_ATOMIC is not needed in sctp_setsockopt_events
  sctp: add a ceiling to optlen in some sockopts
  sctp: make use of pre-calculated len
