Hello, the sys-kernel/vserver-sources-2.1.1_rc21-r3 package is no more in the portage tree. In fact, i'm not sure if i'm at the right place for asking help. Anyway, here is my problem ;) First, vserver was working well on my computer until i decided to change for gcc 4.1.1 in place of gcc 4.2 ... and remerge the whole world again. I tried different vserver and kernel versions, i generated new vserver client in case there was some incompatibilites between versions, but i get always the same exec-ulimit error complaining about a bad address exec-ulimit: execv(): Bad address The last version of the kernel that has worked perfectly was linux-2.6.16-vserver-2.1.1-rc21-r3. Currently, i'm using kernel 2.6.17.1 vanilla + patch-2.6.17-vs2.1.1-rc24.diff but without much success. Of course i tried gentoo 2.7.17 kernel version + vserver patch as well ! Here is my configuration: Portage 2.1.1_pre1-r5 (default-linux/amd64/2006.0, gcc-4.1.1, glibc-2.4-r3, 2.6.17.1-vs2.1.1-rc24 x86_64)================================================================= System uname: 2.6.17.1-vs2.1.1-rc24 x86_64 AMD Athlon(tm) 64 Processor 3200+ Gentoo Base System version 1.12.1 distcc 2.18.3 x86_64-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.3 [enabled] dev-lang/python: 2.4.2 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.3 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.17.50.0.2 sys-devel/gcc-config: 1.3.13-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.16 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O3 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/lib/mozilla-thunderbird/components/myspell /usr/share/X11/xkb /var/qmail/alias /var/qmail/control /var/vpopmail/domains /var/vpopmail/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/splash /etc/terminfo" CXXFLAGS="-march=k8 -O3 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks metadata-transfer sandbox sfperms strict userpriv" GENTOO_MIRRORS="http://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo/ ..."

Not the same but always about bad address ;) vserver start gentoo-template returns, Failed to create new namespace: Bad address An error occured while trying to setup the context for 'gentoo-template'

okay!!!! i have found the culprit lol dev-libs/dietlibc it works great with 0.28 release... Flags i changed, CFLAGS="`echo $CFLAGS | /usr/bin/sed -e s/-O3/-O2/`" CFLAGS="`echo $CFLAGS | /usr/bin/sed -e s/-fno-stack-protector-all//`" without the above one it doesn't compile and CXXFLAGS="`echo $CXXFLAGS | /usr/bin/sed -e s/-O3/-O2/`" for sys-cluster/util-vserver, i changed CFLAGS="`echo ${CFLAGS} | /usr/bin/sed -e s/-O3/-O2/`" CXXFLAGS="`echo $CXXFLAGS | /usr/bin/sed -e s/-O3/-O2/`" i don't think all the modified flags are necessary I will investigate further and let you know :)
summery ------- Sure, i never compiled dietlibc 0.28 with gcc 4.1.1 and above before. Certainly because it didn't compile at all. Certainly i had upgraded dietlibc with the 0.30 version which doesn't work correctly with the util-vserver package. Here begins all my vserver issues. What i have found, it is not necessary to lower CFLAGS optimization flag, sys-cluster/util-vserver works well with -O3 same for dev-libs/dietlibc but -fno-stack-protector-all needs to be discarded.That flag is uncompatible with gcc 4.1.1 release And definitely don't use the last dev-libs/dietlibc-0.30 Hope that helps someone.

To compile dietlibc-0.28 with gcc 4.1.1 you need to take "no-stack-protector-all" off from the package. Otherwise it doesn't compile as you can see below: >>> Compiling source in /var/tmp/portage/dietlibc-0.28/work/dietlibc-0.28 ... mkdir bin-x86_64 gcc -I. -isystem include -march=k8 -O2 -pipe -D__dietlibc__ -fno-stack-protector-all -fno-stack-protector -c x86_64/start.S -o bin-x86_64/start.o gcc -I. -isystem include -march=k8 -O2 -pipe -D__dietlibc__ -fno-stack-protector-all -fno-stack-protector -c dyn_start.c -o bin-x86_64/dyn_start.o cc1: erreur: option "-fno-stack-protector-all" de la ligne de commande non reconnue gcc -I. -isystem include -march=k8 -O2 -pipe -D__dietlibc__ -fno-stack-protector-all -fno-stack-protector -c dyn_stop.c -o bin-x86_64/dyn_stop.o gcc -I. -isystem include -march=k8 -O2 -pipe -D__dietlibc__ -fno-stack-protector-all -fno-stack-protector -c x86_64/unified.S -o bin-x86_64/unified.o make: *** [bin-x86_64/start.o] Erreur 1 make: *** Attente des t

after having investigated this a bit more, we have found out that the environ pointer to execve gets corrupted with gcc 4.1.1 but not with gcc 3.4.6 (no other versions tested) see the attached gdb outputs, you will notice that %rdx is corrupted in the gcc411 register dump... unfortunately we haven't found a fix yet, since all other execve (in util-vserver) work great..
Created attachment 94035 [details] gcc 3.4.6 gdb
Created attachment 94036 [details] gcc 4.1.1 gdb
this should be fixed in 0.30-r1, please test
