# Add targeted selinux policy
Patch0: cjdns.selinux.patch
# Allow python2.6 for build.  Python is not used during the build
# process.  The python tools allegedly depend on python2.7, but that can
# be in Requires for the subpackage.
Patch1: cjdns.el6.patch
# Fix RLIMIT_NPROC - setuid() bug.   In its low priv process, cjdroute calls 
#
#   setrlimit(RLIMIT_NPROC, &(struct rlimit){ 0, 0 })
#
# which on recent kernels prevents fork() or exec() after the following
# setuid().  This is due to changes discussed here:
#
# https://lwn.net/Articles/451985/
# 
# On the 2.6.32 kernel used by EL6, the above causes setuid() to fail.
# This patch sets RLIMIT_NPROC to { 1, 1 } instead, which prevents
# fork(), but not exec, and calls setgroups() before setuid().
Patch2:  cjdns.nprocs.patch
# Change defaults generated by cjdroute --genconf
Patch4:  cjdns.genconf.patch
# Patch contributed init scripts to put cjdroute in /usr/sbin and
# add additional service options.
Patch5:  cjdns.sbin.patch
# Patch make.js to use dynamic nacl library
Patch6:  cjdns.dyn.patch
# Patch to use _LINUX_CAPABILITY_3

%description
Cjdns implements an encrypted IPv6 network using public-key cryptography for
address allocation and a distributed hash table for routing. This provides
near-zero-configuration networking, and prevents many of the security and
scalability issues that plague existing networks.
