Subject: [PATCH 0/3] sunrpc: Fix reserved port range calculation and possible panic
Date: Fri, 8 Jul 2016 16:35:22 -0500 [thread overview]
Message-ID: <1468013725-22835-1-git-send-email-sorenson@redhat.com> (raw)
The range calculation for choosing the random reserved port will panic
with divide-by-zero when min_resvport == max_resvport, a range of one
port, not zero.
In addition, the sysctl and kernel module parameters only limit the
min_resvport and max_resvport values to the entire range of allowed
ports, so the min and max may become inverted, with max_resvport
set to a value lower than min_resvport.
These patches address both issues by correcting the port range
calculation and setting the min_resvport/max_resvport limits
to be dependent on each other.
