[PATCH 0/4] Small, assorted "hardening" fixes

[Stefano Brivio <sbrivio@redhat.com>]

All harmless issues as far as I can tell, but nice to fix.

Stefano Brivio (4):
  conf: Copy up to MAXDNSRCH - 1 bytes, not MAXDNSRCH
  tcp_splice: Check return value of setsockopt() for SO_RCVLOWAT
  util, lineread, tap: Overflow checks on long signed sums and
    subtractions
  tap: Drop frames from guest whose length is more than remaining buffer

 conf.c       |  2 +-
 lineread.c   |  5 +++--
 tap.c        | 24 ++++++++++++++++++------
 tcp_splice.c | 15 ++++++++++-----
 util.c       |  7 +++++--
 util.h       | 46 +++++++++++++++++++++++++++++++++++++++++++++-
