The solution was either to add a Q+A to the FAQ or fix the port. This introduce a new variable, FreeBSD5, that is set to "yes" if we're running FreeBSD 5 or higher. This variable is used to fix the tests of the following binaries, so they would DTRT on FreeBSD 5: chfn chsh date ls ps I also fixed a bug in the cheking of vdir, but it's irrelevant for FreeBSD. >How-To-Repeat: Install the port and run on FreeBSD 5 and higher. You'll also need to remove the IGNORE from the Makefile. >Fix: --- chkrootkit-5fix begins here --- diff -urN chkrootkit.orig/Makefile chkrootkit/Makefile --- chkrootkit.orig/Makefile Sun Aug 24 11:25:09 2003 +++ chkrootkit/Makefile Sun Aug 24 12:11:46 2003 @@ -23,10 +23,6 @@ .include <bsd.port.pre.mk> -.if ${OSVERSION} >= 500000 -IGNORE= "Reports false positives on 5.x" -.endif - pre-patch: ${REINPLACE_CMD} -e "s/^CC/#CC/; s/^CFLAGS/#CFLAGS/" ${WRKSRC}/Makefile ${REINPLACE_CMD} -e \ diff -urN chkrootkit.orig/files/patch-chkrootkit chkrootkit/files/patch-chkrootkit --- chkrootkit.orig/files/patch-chkrootkit Thu Jan 1 00:00:00 1970 +++ chkrootkit/files/patch-chkrootkit Sun Aug 24 12:08:51 2003 @@ -0,0 +1,84 @@ +--- chkrootkit.orig Sun Aug 24 12:04:58 2003 ++++ chkrootkit Sun Aug 24 12:08:26 2003 +@@ -1020,8 +1020,10 @@ + STATUS=${INFECTED} + fi;; + FreeBSD) ++ TMP="2" ++ if [ "${FreeBSD5}" = "yes" ]; then TMP="1"; fi + if [ `${strings} -a ${CMD} | \ +- ${egrep} -c "${GENERIC_ROOTKIT_LABEL}"` -ne 2 ] ++ ${egrep} -c "${GENERIC_ROOTKIT_LABEL}"` -ne "${TMP}" ] + then + STATUS=${INFECTED} + fi;; +@@ -1053,7 +1055,9 @@ + fi + fi;; + FreeBSD) +- if [ `${strings} -a ${CMD} | ${egrep} -c "${GENERIC_ROOTKIT_LABEL}"` -ne 2 ] ++ TMP="2" ++ if [ "${FreeBSD5}" = "yes" ] ; then TMP="1"; fi ++ if [ `${strings} -a ${CMD} | ${egrep} -c "${GENERIC_ROOTKIT_LABEL}"` -ne "${TMP}" ] + then + STATUS=${INFECTED} + fi;; +@@ -1264,7 +1268,10 @@ + return 5 + fi + +- if ${strings} -a ${CMD} | ${egrep} "${LS_INFECTED_LABEL}" >/dev/null 2>&1 ++ TMP="0" ++ if [ "${FreeBSD5}" = "yes" ] ; then TMP="1"; fi ++ if [ `${strings} -a ${CMD} | \ ++ ${egrep} -c "${LS_INFECTED_LABEL}"` -ne "${TMP}" ] + then + STATUS=${INFECTED} + fi +@@ -1342,7 +1349,10 @@ + return 5 + fi + +- if ${strings} -a ${CMD} | ${egrep} "${PS_I_L}" >/dev/null 2>&1 ++ TMP="0" ++ if [ "${FreeBSD5}" = "yes" ] ; then TMP="1"; fi ++ if [ `${strings} -a ${CMD} | \ ++ ${egrep} -c "${PS_I_L}"` -ne "${TMP}" ] + then + STATUS=${INFECTED} + fi +@@ -1560,7 +1570,10 @@ + return 5 + fi + +- if ${strings} -a ${CMD} | ${egrep} "${GENERIC_ROOTKIT_LABEL}" > /dev/null 2>&1 ++ TMP="0" ++ if [ "${FreeBSD5}" = "yes" ] ; then TMP="2"; fi ++ if [ `${strings} -a ${CMD} | \ ++ ${egrep} -c "${GENERIC_ROOTKIT_LABEL}"` -ne "${TMP}" ] + then + STATUS=${INFECTED} + fi +@@ -1750,7 +1763,7 @@ + STATUS=${NOT_INFECTED} + CMD=`loc vdir vdir $pth` + VDIR_INFECTED_LABEL="/lib/volc" +- if [ -r ${CMD} ]; then ++ if [ ! -r ${CMD} ]; then + return ${NOT_FOUND} + fi + +@@ -2323,6 +2336,13 @@ + + SYSTEM=`${uname} -s` + VERSION=`${uname} -r` ++ ++if [ "${SYSTEM}" = "FreeBSD" ] ; then ++ if [ -n '`uname -r | grep "^5"`' ] ; then ++ FreeBSD5="yes" ++ fi ++fi ++ + if [ "${SYSTEM}" != "FreeBSD" -a ${SYSTEM} != "OpenBSD" ] ; then + V=44 + else --- chkrootkit-5fix ends here --- >Release-Note: >Audit-Trail: >Unformatted:
