Bug ID: 192544
Summary: [kern] values returned from some sysctls broken on
CURRENT
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: yaneurab...@gmail.com
hiren@/jmg@ noted that the output from certain sysctls appears to be broken in
recent versions of CURRENT. In particular, it seems to be returning a single
nul terminated string instead of a full string for net.inet.tcp.cc.algorithm
(and friends):
$ uname -o -r
FreeBSD 9.2-RELEASE-p10
$ sysctl net.inet.tcp.cc.algorithm
net.inet.tcp.cc.algorithm: newreno
# uname -a
FreeBSD isilon-fuji-current.local 11.0-CURRENT FreeBSD 11.0-CURRENT #16
r268804+343692e(isilon-atf): Mon Jul 14 12:17:25 PDT 2014
root@isilon-fuji-current.local:/usr/obj/usr/src/sys/FUJI i386
# sysctl net.inet.tcp.cc.algorithm
net.inet.tcp.cc.algorithm: n
Is some of the new code after recent sysctl(9) refactoring not properly
dereferencing memory?
