Subject: [PATCH 0/5] selinux: minor cleanup suggestions

A few random things I stumbled on.

While I'm pretty sure of the change in 1/5, I'm also confused, because
the doc for the reverse security_sid_to_context state that
@scontext_len is set to "the length of the string", which one would
normally interpret as being what strlen() would give (i.e., without
the \0). However, security_sid_to_context_core clearly includes the \0
in the return value, and I think callers rely on that.

Rasmus Villemoes (5):
  selinux: introduce security_context_str_to_sid
  selinux: remove pointless cast in selinux_inode_setsecurity()
  selinux: use kmemdup in security_sid_to_context_core()
  selinux: use kstrdup() in security_get_bools()
  selinux: use sprintf return value
