Analyser l’impact d’une mise à jour ESXi

Posted on 17 avril 2017Leave a comment

Lorsqu’on met à jour à la main un ESXi, il est possible d’analyser les paquets qui vont être installés, ceux qui vont être mis à jour, et ceux qui ne vont pas être touchés. On a alors une sortie qui ressemble à ça.

~ # esxcli software profile update --dry-run -p ESXi-5.1.0-20160504001-standard \
> -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

Comme on peut le voir, il est difficile d’avoir une vue claire permettant de savoir quel paquet va être mis à jour et en quelle version. J’ai à ces fins écris un petit script en PowerShell permettant d’améliorer la lisibilité de la sortie.

$result | ft PackageName, OldVersion, NewVersion, SkipVersion

Il suffit de remplacer le contenu de $in par ta sortie et $result contiendra désormais la liste des packages impactés avec la version d’origine et la version de destination. Il est de même rapide de voir les paquets définitivement supprimés, les nouveaux et ceux qui ne seront pas impactés par la mise à jour.

Description de l’authentification via NTLM en HTTP

Petit article que j’ai déniché expliquant comment fonctionne une authentification avec un site web utilisant le fournisseur NTLM. Note: je ne dis pas si c’est bien ou pas d’utiliser NTLM, juste de savoir comment ça marche.

Cela explique toutefois pourquoi je n’arrive pas à reverse-proxifier un site web qui utilise NTLM pour authentifier le client avec nginx.

NTLM Authentication Scheme for HTTP

rc-status ne voit pas crond

Posted on 9 avril 2017Leave a comment

J’ai observé sur mon routeur Alpine que le daemon crond affichait tout le temps crashed.

apu:~# rc-status
Runlevel: default
[...]
 crond                                               [  crashed  ]
[...]

Alors même qu’il était vivant vu que pidof crond me renvoyait bien un PID.

Une analyse du script init.d revèle que le pid devrait se trouver dans le fichier /var/run/crond.pid . Que nenni mon ami, ce fichier contient un PID inexistant, voilà pourquoi rc-status affiche n’importe quoi !

C’est courant lorsque le script init.d récupère le PID du process qu’il lance, alors que ce dernier se fork encore une fois afin de pouvoir fonctionner en background.

On va résoudre ça vite fait. Examinons s’il est possible que crond crée le pid file, ou alors qu’il ne passe pas en arrière plan lui-même mais laisse faire start-stop-daemon.

apu:~# crond -h
dillon's cron daemon 4.5
crond [-s dir] [-c dir] [-t dir] [-m user@host] [-M mailer] [-S|-L [file]] [-l level] [-b|-f|-d]
-s            directory of system crontabs (defaults to /etc/periodic)
-c            directory of per-user crontabs (defaults to /etc/crontabs)
-t            directory of timestamps (defaults to /var/spool/cron/cronstamps)
-m user@host  where should cron output be directed? (defaults to local user)
-M mailer     (defaults to /usr/sbin/sendmail)
-S            log to syslog using identity 'crond' (default)
-L file       log to specified file instead of syslog
-l loglevel   log events <= this level (defaults to notice (level 5))
-b            run in background (default)
-f            run in foreground
-d            run in debugging mode

Au vu des paramètres possibles, je dirais qu’on va tester crond en foreground. On édite donc /etc/conf.d/crond pour préciser à crond de rester en background.

# enter the cron options
CRON_OPTS="-c /etc/crontabs -f"

Et on relance le service avec rc-service crond restart . Et voilà c’est terminé ! … et là on remarque qu’il n’y a plus de crond du tout ! Et pas de messages d’erreur non plus.

Aux grand maux les grands remèdes, je sors l’artillerie lourde afin de comprendre ce qu’il s’est passé pour de vrai. Le passage intéressant est à la fin; il n’est pas nécessaire de lire toutes ces horreurs.

Je ne sais pas pourquoi j’ai autant de EBADF, mais ce n’est pas ce flood qui est responsable du problème. On observe que crond a bien été lancé, puis il tente un appel à setpgid qui se solde par un échec, suivi presque immédiatement d’une mort du process.

Il se trouve justement qu’un ticket a été ouvert concernant ce problème avec setpgid. Pour ma part, ne voyant absolument pas à quoi ce truc sert, le man étant particulièrement inutile à fournir une explication claire, j’ai fait au plus simple en modifiant l’init.d plutôt que le code source de dcron.

C’est très clairement dégueulasse mais ça marche. Tu veux voir le résultat 😀 :

#!/sbin/openrc-run

name="busybox $SVCNAME"
command="/usr/sbin/$SVCNAME"
pidfile="/var/run/$SVCNAME.pid"
command_args="$CRON_OPTS"
#command_background=yes
#start_stop_daemon_args="-b -m"

depend() {
        need localmount
        need logger
}

start_post() {
        local pids pid ppid

        pids=`pidof $SVCNAME`
        pid=0

        for pid in $pids; do
                ppid=`grep '^PPid:' /proc/$pid/status | grep -o '[0-9]*'`

                if [ "$ppid" = '1' ]; then
                        echo "$pid" > $pidfile
                        return 0;
                fi
        done
}

J’avais prévenu… En attendant une éventuelle résolution du ticket, c’est une solution raisonnable.

Mise à jour du firmware de mon SSD, the hard way

Posted on 9 avril 2017Leave a comment

J’ai un SSD pour lequel le constructeur a sorti une mise à jour du firmware. Il s’agit du modèle M550 de chez Crucial qui passe de la version M01 à la version M02. Ce SSD est au format mSata, dans mon routeur qui est un APU1 de PCEngines. Ce routeur n’a pas de sortie vidéo, ne fonctionne pas sous Windows mais sous Linux, et n’a pas de lecteur CD. Quelque chose me dit que cela ne va pas me prendre 5 minutes…

Pour mettre à niveau le firmware, je dispose de deux possibilités :

connecter le SSD sur une autre machine plus « standard » et faire la mise à jour depuis cette machine. J’aurais bien opté pour cette solution si j’avais eu un adaptateur SATA > mSATA, et puis cela aurait été moins fun, non ?
mettre à jour directement le SSD sans utiliser le tournevis

Crucial met à disposition le package de mise à niveau sous la forme d’une image CD. Je pourrais éventuellement brancher un lecteur CD en USB au routeur, voire même modifier le bootloader pour booter directement sur l’iso mais il est fort à parier que le CD n’a pas été prévu pour un contrôle depuis le port série, voie sans issue donc.

CD, dis-moi qui tu es

Explorons un peu le contenu de cette image.

On commence à avoir des choses intéressantes. Le CD contient un noyau linux (vmlinuz) et le bootloader est isolinux, un standard pour booter du linux depuis un CD ou une clé USB. Je serais tombé sur une mise à jour basée sur DOS (Caldera DOS, FreeDOS…), j’aurais été bon pour acheter l’adaptateur.

Examinons le fichier de configuration du bootloader:

DEFAULT sd

LABEL sd
KERNEL /boot/vmlinuz
INITRD /boot/core.gz
APPEND quiet base loglevel=3 waitusb=10 superuser rssd-fw-update rssd-fwdir=/opt/firmware rssd-model=M550

On remarque un certain nombre de paramètres non standard, ainsi que le initrd.

Hacking the kernel

Pour continuer l’analyse de l’iso, je redémarre redémarre le routeur sur la sdcard (système de secours si le ssd lache) afin de laisser totalement inutilisé le SSD, puis copier le contenu de l’iso dans disons /tmp/crucial/iso . Qui dit initrd dit cpio. Je décompresse donc core.gz puis extrayons le contenu de l’archive cpio dans /tmp/crucial/root .

Le point d’entrée par défaut est le script /init , vu qu’il n’a pas été redéfini dans les paramètres envoyés au kernel.
Il est d’une extrême simplicité et se résume à :

monter /proc
lancer /sbin/init

init , s’il s’agit du bon vieux process racine servant à faire fonctionner Linux, va se servir de /etc/init.d afin d’initialiser les différentes partie du système. Certains de ces scripts sont reconnaissable (rc.shutdown) voir inutile à vue (dhcp.sh, settime.sh…). Il y en a un toutefois qui retient mon attention : msd-config.sh car son nom ne m’est absolument pas familier.

Bingo ! Ce script, simple également, récupère les paramètres envoyés au kernel, via le fichier /proc/cmdline , et lancer le processus msecli avec les paramètres adéquat. Il va notamment utiliser le paramètre kernel rssd-model=M550 , ce qui me conforte que je suis bien sur la bonne piste, le M550 étant pour rappel le modèle de mon SSD.

Au final, le script exécutera la commande suivante : /sbin/msecli -U -i /opt/firmware -m M550 -y .

Allons-y :

apu:/tmp/boot/root# ./sbin/msecli --help
-ash: ./sbin/msecli: not found
apu:/tmp/boot/root# ll ./sbin/msecli
-rwxr-xr-x    1 root     root      635.5K Apr  9 14:22 ./sbin/msecli
apu:/tmp/boot/root# ldd ./sbin/msecli
ldd: ./sbin/msecli: Not a valid dynamic program

Le fichier est bien présent, pourtant il n’est pas possible de l’exécuter. C’est plutôt bizarre…

Go down the rabbit hole

Une analyse sauvage du fichier (sous vim) m’apprend qu’il s’agit d’un exécutable non statique, c’est à dire qu’il utilise des librairies chargées dynamiquement. Sachant que le Linux hôte est Alpine Linux, la libc en vigueur n’est pas l’immonde glibc mais musl. Comme indiqué ci-dessous, la présence de /lib/ld-linux.so.2 trahit le caractère dynamique de l’exécutable. Cela explique également pourquoi le ldd sur l’hôte n’est pas parvenu à parser correctement l’exécutable.

Done ! La mise à jour est passé sans soucis. Je reboot sur le SSD pour le réinitialiser et repasser sur le système principal pour confirmer que tout s’est bien passer.

Parce qu’Un script vaut mille mots

Ci-dessous un résumé scripté des étapes que j’ai du suivre pour mettre à jour le SSD depuis Linux et sans booter sur l’iso :

#!/bin/sh

ROOT_CRUCIAL_ISO=/tmp/crucial/iso
ROOT_CRUCIAL=/tmp/crucial/root

mkdir -p "$ROOT_CRUCIAL"
gunzip "${ROOT_CRUCIAL_ISO}/boot/core.gz
pushd "$ROOT_CRUCIAL"
cpio -F "${ROOT_CRUCIAL_ISO}/boot/core" -i
popd

# mounting /proc is mandatory for the cli to properly work
mount -t proc none "${ROOT_CRUCIAL}/proc/"
mount --rbind /sys "${ROOT_CRUCIAL}/sys/"

# in case where the kernel has grsecurity enabled, we need to allow CAPS in the chroot
echo 0 > /proc/sys/kernel/grsecurity/chroot_caps 2> /dev/null

chroot "$ROOT_CRUCIAL" sh
msecli -U -i /opt/firmware -m M550

Unbrick Synology

J’ai trouvé un article décrivant comment il peut être possible d’installer un OS, en l’occurrence NetBSD, sur du matériel Synology. Je doute d’en arriver là, mais pour avoir déjà brické mon NAS deux fois, cela peut toujours être utile. En effet, la procédure détaille comment accéder à l’interface série et donc permettre d’avoir des informations lors du boot.

Le tuto est là : Synology Diskstation Installation

Et pour démonter son NAS, plusieurs tuto/vidéos existent. Pour upgrader mon DS412+ à 2Go de RAM, j’avais notamment regardé cette vidéo: Synology DS412+ RAM Upgrade – Disassembly Tuto
