Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  accept() system call is inconsistent with bind(), connect()

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Under kernel 3.2.0-54 and 3.9.3 (at least), the accept() system call
  in a PF_LOCAL, AF_LOCAL, SOCK_STREAM context returns an addrlen for
  the sockaddr_un structure that is too large by one.

  As the SUN_LEN macro of the sys/un.h header shows, the "length" of the
  structure is expected to be the strlen() of the sun_path member, plus
  that member's offset.  This is the length used by bind() and
  connect(), in particular.  But accept() consistently returns a
  "length" which includes the trailing null, and is thus too large by
  one.
