Wed, 24 Feb 2010 17:39:21 +0100 Hello, I encountered a (big) problem because the namespace cleanup functionality doesn't work always well. Test case : Start a Vserver named "webmail", vdir located under the mount point "/vservers/webmail" The start another VServer "web", vdir mounted under "/vservers/web" (same beginning ...) The first mount point is not umounted in the namespace of the second VServer. (vnamespace -e <xid of web> cat /proc/mounts) From what I understand, the problem is located at the namespaceCleanup function, the test for not umounting a sub-mount is not correct. One solution, verify the path with a trailing "/" --- util-vserver/vserver.functions.orig 2010-02-24 17:29:29.000000000 +0100 +++ util-vserver/vserver.functions 2010-02-24 17:34:13.000000000 +0100 @@ -1378,7 +1378,8 @@ while read -r dev path opts; do test -n "$path" || continue for i in "$root" /dev /proc; do - test "${path#$i}" != "$path" && continue 2 + path dir="${path}/" + test "${path dir#${i}/}" != "${path dir}" && continue 2 done for i in "${list[@]}" /; do test "$path" = "$i" && continue 2 -- Xavier Montagutelli Tel : +33 (0)5 55 45 77 20 Service Commun Informatique Fax : +33 (0)5 55 45 75 95 Universite de Limoges 123, avenue Albert Thomas 87060 Limoges cedex
