Supportdata2[edit]

Introduction[edit]

supportdata is intended for the AVM support and already is a valuable source of information.
The biggest advantage of supportdata is that it can be created by everyone on unmodified firmware.
And that is very important to have correct scan results about plain FRITZ!OS for this Wiki.

But BoxMatrix is hungry for more than what is extractable from Supportdata-Probes.
Stuff which is of no interest to the AVM support but will help to fill some empty sections:

So far these lists are extracted from Supportdata2 probes, each entry with a per model reference:

59 Benchmark-Results 34 4.07 - 7.90 CPUinfo-Properties Box-Models
2196 objects collected in 8 sections

Usage[edit]

The script sd2 is provided collecting all the wanted additional info.
It could be run in a telnet or ssh session on original or modified firmware with access to the internet.
If a box is offline you can put sd2 on an USB-Stick. Maybe you need to copy it to /var/tmp to execute it.

Since the wget command of busybox (no HTTPS) is present on every box sd2 is hosted accessible by HTTP.
The usage is simple for the helper, one single command line, and you can always peek the source code: 

cd /var/tmp       # only on original firmware - freetz cd is /var/mod/root

rm -f sd2 && wget boxmatrix.info/sd2 && chmod +x sd2 && ./sd2

Add -t <server> to TFTP, -m to Mail, -l to List and / or -d to Delete the created file at the end of the bold line above.
Alternatively send the created file as an Email attachment to hippie2000@webnmail.de.
If the -r option is passed sd2 is refetched before it's executed, either from BoxMatrix or from a specified TFTP server. 

tftp -g -r sd2 192.168.178.20 && chmod +x sd2 && ./sd2 -r -t 192.168.178.20

Output[edit]

The filename of the sd2 generated output identifies a model, its firmware and its branding, easy to parse by my scanner.

>&2 echo "Creating BocMatrix Supportdata2"

echo "##### BEGIN SD2 ${version} '${file}'"

Normally sd2 will log stdout (echo) to filenames like the following, output to stderr (>&2 echo) will be printed: 

sd2-02-FRITZ!Box 6490 Cable-213-0-141-07.29-0-avm-Kabel-049-en-1653475087.txt
sd2-02-FRITZ!Box 7520-247-2-175-07.29-0-avm-B-049-de-1653475087.txt

If the -s option is passed (stdout mode) no file is created and stderr is muted.

Listings[edit]

Here step by step listings created by sd2 and how they are gathered will be added.

Modding[edit]

To analyze how the firmware was modified some details about freetz or possible other mods are collected, if present.
This must remain the first section so the scanner can detect sections which do not represent FRITZ!OS in a single pass: 

if [ -e /etc/freetz_info.cfg ] ; then

    >&2 echo "Listing freetz info"
    echo "##### SECTION freetz_info"
    echo

    cat /etc/freetz_info.cfg
    echo

fi

if [ -e /etc/packages.lst ] ; then

    >&2 echo "Listing freetz packages"
    echo "##### SECTION freetz_packages"
    echo

    cat /etc/packages.lst
    echo

fi

if [ -e /etc/.config ] ; then

    >&2 echo "Listing freetz build config"
    echo "##### SECTION freetz_config"
    echo

    cat /etc/.config        
    echo

fi

if [ -e /var/flash/freetz ] ; then

    >&2 echo "Listing freetz tffs config"
    echo "##### SECTION freetz_tffs"
    echo

    cat /var/flash/freetz | tar tvf - 2>/dev/null
    echo

fi

if [ -d /var/mod ] ; then

    >&2 echo "Listing freetz temp files"
    echo "##### SECTION freetz_temp"
    echo

    ls -lRa /var/mod
    echo

fi

Versions[edit]

There are several places in FRITZ!OS to gather version info.
This must remain the second section so the scanner can use this info for all subsequent data in a single pass: 

>&2 echo "Listing local versions"
echo "##### SECTION versions_local"
echo

echo "# version:"
cat /proc/version
echo

echo "# uname:"
uname -a
echo

echo "# tainted:"
cat /proc/sys/kernel/tainted 2>/dev/null
echo

echo "# gcc:"
grep GCC /bin/allcfgconv 2>/dev/null
echo

echo "# uptime:"
cat /proc/uptime
echo

echo "# developers:"
cat /proc/avalanche/developers 2>/dev/null
echo

echo "# boardinfo:"
cat /proc/boardinfo 2>/dev/null
echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote versions"
    echo "##### SECTION versions_remote"
    echo
 
    echo "# version:"
    rpc cat /proc/version
    echo

    echo "# uname:"
    rpc uname -a
    echo

    echo "# tainted:"
    rpc cat /proc/sys/kernel/tainted
    echo

    echo "# gcc:"
    rpc grep GCC /bin/allcfgconv 2>/dev/null
    echo

    echo "# uptime:"
    rpc cat /proc/uptime
    echo

    echo "# developers:"
    rpc cat /proc/avalanche/developers
    echo

 fi

The uptime may be useful to detect if a boot was finished.

CPUinfo[edit]

cpuinfo is an important helper to gather runtime information about the builtin CPUs to be collected in the Codenames section.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote cpuinfo. 

>&2 echo "Listing local cpuinfo"
echo "##### SECTION cpuinfo_local"
echo

echo "# cpuinfo:"
cat /proc/cpuinfo
echo

echo "# clocks:"
cat /proc/clocks 2>/dev/null
echo

echo "# smtc:"
cat /proc/smtc 2>/dev/null
echo

echo "# psp_version:"
cat /proc/avalanche/psp_version 2>/dev/null
cat /proc/avalanche/base_psp_version 2>/dev/null
echo
 
if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote cpuinfo"
    echo "##### SECTION cpuinfo_remote"
    echo

    echo "# cpuinfo:"
    rpc cat /proc/cpuinfo
    echo

    echo "# psp_version:"
    rpc cat /proc/avalanche/base_psp_version
    echo

fi

Benchmarks[edit]

Benchmarks are also a topic on BoxMatrix to compare models. They are collected in the new Benchmark-Results section.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote Benchmarks.
The MemBench code is ugly, but it's at differing locations. 

if [ "${benchmark}" != "" ] ; then

    >&2 echo "Listing local benchmarks"
    echo "##### SECTION benchmarks_local"
    echo

Meminfo[edit]

Interrupts[edit]

Interrupts are not covered in supportdata at all, so this will fill the gaps.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote interrupts.

Symlinks[edit]

Symlinks are already scanned from Firmware-Probes but it may be helpful for debugging modified firmware to list them.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote symlinks
This section must be grabbed before the BusyBox section to avoid the need of a 2-path sd2 listing parser. 

if [ -x /usr/bin/find ] ; then

    >&2 echo "Listing local symlinks"
    echo "##### SECTION symlinks_local"

        rpc find /bin /sbin /usr/bin /usr/sbin -type l | sort 2>/dev/null
        echo
 
    fi

fi

BusyBox[edit]

BusyBox-Commands are already scanned from Firmware-Probes but it may be helpful for debugging modified fw to list them.
Since the --list option is not present in older busybox we have to call busybox without arguments for compatibility.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote busybox. 

>&2 echo "Listing local busybox applets"
echo "##### SECTION busybox_local"
echo

busybox 2>&1
echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote busybox applets"
    echo "##### SECTION busybox_remote"
    echo

    rpc busybox 2>&1
    echo

Processes[edit]

Linux-Processes are already present in supportdata but to map them to Netlink data they need to be grabbed at the same time.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote processes.
This section must be grabbed before the Netlink section to avoid the need of a 2-path sd2 listing parser. 

>&2 echo "Listing local processes"
echo "##### SECTION processes_local"
echo

ps -l 2>/dev/null
if [ $? -ne 0 ] ; then
    ps -w 2>/dev/null
fi
echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote processes"
    echo "##### SECTION processes_remote"
    echo

    rpc ps -l
    echo

fi

The -T option was removed since older ps fails on it. Option -l also fails on older systems in which case -w is used.

Netperf[edit]

Network-Performance comparison is still a missing feature on BoxMatrix.
Step by step tesing methods will be added here 

if [ "${benchmark}" != "" ] ; then

    >&2 echo "Listing local net performance"
    echo "##### SECTION netperf_local"
    echo

fi

Sockets[edit]

Linux-Sockets are already present in supportdata but to map them to AVMIPC data they need to be grabbed at the same time.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote sockets.
This section must be grabbed before the AVMIPC section to avoid the need of a 2-path sd2 listing parser. 

>&2 echo "Listing local sockets"
echo "##### SECTION sockets_local"
echo

netstat -xlpen 2>/dev/null
if [ $? -ne 0 ] ; then
    netstat -xlen 2>/dev/null
fi
echo

netstat -xpen 2>/dev/null
if [ $? -ne 0 ] ; then
    netstat -xen 2>/dev/null
fi
echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote sockets"
    echo "##### SECTION sockets_remote"
    echo

    rpc netstat -xlpen
    echo

    rpc netstat -xpen
    echo

fi

Option netstat -p is missing on older models, in which case it retries without.

Genetlink[edit]

Genetlink sockets are the NETLINK_GENERIC family of Netlink-Sockets, maintained by libewnwlinux.so in FRITZ!OS.
They could be listed from aicmd listeners which call the genetlink_ functions in libewnwlinux.so.
So far these are only l2tpv3d, nltest and active users of libavmpcp.so and no remote daemon so far.
For maximum independency of the mode a box is using we query ctlmgr, dsld, multid, l2tpv3d.
This section must be grabbed before the Netlink section to avoid the need of a 2-path sd2 listing parser. 

if [ -x /bin/aicmd ] ; then

    >&2 echo "Listing local genetlink sockets"
    echo "##### SECTION genetlink_local"
    echo

    for daemon in ctlmgr dsld multid l2tpv3d; do

        aicmd $daemon ewnwlinux show genetlink 2>/dev/null

    done
    echo

fi

Netlink[edit]

Netlink-Sockets are similar to Linux-Sockets just they are not files in the filesystem so they don't appear in supportdata.
We list them from the procfs. If rpc exists we are on a Puma6 or Puma7 model and also list the remote netlink sockets. 

>&2 echo "Listing local netlink sockets"
echo "##### SECTION netlink_local"
echo

cat /proc/net/netlink
echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote netlink sockets"
    echo "##### SECTION netlink_remote"
    echo

    rpc cat /proc/net/netlink
    echo

fi

AVMIPC[edit]

The AVMIPC-Datastore is pretty new, the aicmd command to show it even newer (6.54), we must check if it exists.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote datastore.
Older avmipcd has a differing syntax to list the datastore, and aicmd does not set an error rerturn code on failure.
So we run new and old syntax silently after each others, one will (hopefully) succeed. Tested with fw 7.01 - 7.39.
In fw 6.88 aicmd exists but could not list the datastore since avmipcd was no aicmd listener yet. This also fails silently. 

if [ -x /bin/aicmd ] ; then

    >&2 echo "Listing local avmipcd datastore"

Filesystems[edit]

The Linux-Filesystems only cover filesystems which are reported by mount, so they are listed here to fill the gaps.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote filesystems. 

>&2 echo "Listing local filesystems"
echo "##### SECTION filesystems_local"
echo

echo "filesystems:"
cat /proc/filesystems
echo

echo "mounts:"

echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote filesystems"
    echo "##### SECTION filesystems_remote"
    echo

    echo "filesystems:"
    rpc cat /proc/filesystems
    echo

    echo "mounts:"
    cat /proc/mounts
    echo

fi

Partitions[edit]

The Linux-Partitions are rarely listed in Supportdata-Probes, so they are listed here to fill the gaps.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote partitions. 

>&2 echo "Listing local partitions"

echo "##### SECTION partitions_local"
echo

echo "# mtd:"
cat /proc/mtd 2>/dev/null && echo

echo "# partitions:"
cat /proc/partitions

    echo

    echo "# avm_partitions:"
    rpc cat /proc/avm_partitions
    echo

fi

UBInfo[edit]

The Linux-Partitions never cover UBI volumes in Supportdata-Probes, so they are listed here to fill the gaps. 

if [ -x /usr/sbin/ubinfo ] ; then

    >&2 echo "Listing local UBI info"

    echo "##### SECTION ubinfo_local"
    echo

    ubinfo --all
    echo

fi

Devices[edit]

The Linux-Devices currently only list devices which are hardcoded in the firmware, which is not used in recent firmware.
It always lacked the numerous devices which are dynamically created at runtime (today all). This listing will fill these gaps.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote devices. 

>&2 echo "Listing local devices"

echo "##### SECTION devices_local"
echo

echo "# devices:"
cat /proc/devices
echo

echo "# misc:"
cat /proc/misc
echo

ls -lRa /dev
echo

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote devices"

    echo "##### SECTION devices_remote"
    echo

    echo "# devices:"
    rpc cat /proc/devices
    echo

    echo "# misc:"
    rpc cat /proc/misc
    echo

    rpc ls -lRa /dev
    echo

fi

Procfs[edit]

The procfs is huge, especially its numerical directories with the pid of each process.
Besides this the processes come and go so a ls -lR would just be bloat for redundant useeless info.
Thats why it has to be listed step by step. First we list all non directories in /proc main directory : 

>&2 echo "Listing procfs"

echo "##### SECTION procfs_local"
echo

echo "/proc:"
ls -la /proc | grep -v '^d'

To have a sample we list the pid 1 process which should not disappear 

echo
${nice} ls -lRa /proc/1 2>/dev/null

Then we list all non numerical subdirectories of /proc recursively 

for obj in /proc/*
do

    [ -d "$obj" ] || continue

    dir=$(basename "$obj")
    [ "$dir" -eq "$dir" ] 2> /dev/null
    [ $? -ne 0 ] || continue 

    echo
    ${nice} ls -lRa "$obj"

done
echo

The first continue filters out all non directories, the second continue filters out all numerical dirs.
If rpc exists we are on a Puma6 or Puma7 model and also list the remote procfs. 

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote procfs"

    echo "##### SECTION procfs_remote"
    echo

    echo "/proc:"
    rpc ls -la /proc | grep -v '^d'
    echo
    rpc ls -la /proc | grep '^d'
    echo

    rpc ${nice} ls -lRa /proc/1 2>/dev/null
    echo

    dirs="P-UNIT avalanche avm bus capi cppi cpu docint driver fs irq sys sysvipc tty"
    for dir in  ${dirs} ; do

        rpc ${nice} ls -lRa "/proc/${dir}"
        echo

    done

fi

Sysfs[edit]

The sysfs is also huge, but unlike the procfs it does not need to be filtered but can be listed recursively 

if [ -e /sys ] ; then

    >&2 echo "Listing local sysfs"

    echo "##### SECTION sysfs_local"
    echo

    ${nice} ls -lRa /sys
    echo

fi

If rpc exists we are on a Puma6 or Puma7 model and also list the remote sysfs. 

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote sysfs"

    echo "##### SECTION sysfs_remote"
    echo

    rpc ${nice} ls -lRa /sys
    echo

fi

Tempfiles[edit]

The Temp-Files just cover stuff AVM lists, they lack locks, pidfiles etc. 

>&2 echo "Listing local tempfiles"

echo "##### SECTION tempfiles_local"
echo

${nice} ls -lRa /var
echo

If rpc exists we are on a Puma6 or Puma7 model and also list the remote tempfiles. 

if [ -x /usr/bin/rpc ] ; then

    >&2 echo "Listing remote tempfiles"

    echo "##### SECTION tempfiles_remote"
    echo

    rpc ${nice} ls -lRa /var
    echo

fi

Urlader[edit]

If the -u option is passed the Urlader is dumped. It is very valuable for research.
If rpc exists we are on a Puma6 or Puma7 model and also dump the remote urlader. 

if [ "${urlader}" != "" -a -x /bin/sed -a -x /bin/dd ] ; then

    dev=$(grep -e bootloader -e '"urlader"' /proc/mtd | sed 's/:.*//' | sed 's/^mtd//')
    if [ "${dev}" != "" -a -e "/dev/mtdblock${dev}" ] ; then

        >&2 echo "Dumping local urlader"

        echo "##### SECTION urlader_local"
        echo

        echo "# urlader"
        blob1="${blob}"
        dd if="/dev/mtdblock${dev}" of="${blob1}" bs=256 2>/dev/null
        echo

        ls -l "${blob1}"
        echo

    fi

    if [ -x /usr/bin/rpc ] ; then

        dev=$(rpc grep -e bootloader -e '"urlader"' /proc/mtd | sed 's/:.*//' | sed 's/^mtd//')
        if [ "${dev}" != "" -a $(rpc ls "/dev/mtdblock${dev}")  != "" ] ; then

            >&2 echo "Dumping remote urlader"

            echo "##### SECTION urlader_remote"
            echo

            echo "# urlader"
            blob2="${blob}2"
            rpc dd if="/dev/mtdblock${dev}" bs=256 >"${blob2}"
            echo

            ls -l "${blob2}"
            echo

        fi

    fi

fi

EOF[edit]

The end marker is important to detect truncated files: 

echo "##### END SD2"

if [ "${stdout}" != "" ] ; then
    exit 0
fi

>&2 echo "Created '${file}'"

If the -s option was passed (stdout mode) sd2 will terminate here since there's no file to process further.

Options[edit]

List[edit]

sd2 can optionally list the created file (using less) if it's passed the -l option.
This is especially useful during development to not have to copy paste the unpredictable filename. 

if [ "${list}" != "" ] ; then

    >&2  echo "Listing created file..."

    if [ -x /usr/bin/less ] ; then
        1>&2 less "${file}"
    else
        1>&2 more "${file}"
    fi

fi

Gzip[edit]

sd2 will automatically compress the created file if gzip could be found, unless the -n option (no gzip) is passed.
A sd2 file is approx. 1 MB, with remote listings 2 MB (6490). Compressed these are both ~100 kB! 

if [ "${nogzip}" = "" -a -x /bin/gzip ] ; then

    >&2 echo "Compressing files with gzip..."

    gzip "${file}"
    if [ $? -eq 0 ] ; then
        >&2 echo "  Gzipped ${file}" 
        file="${file}.gz"
    else
        >&2 echo "  *** FAILED to gzip ${file} ***" 
    fi

    if [ "${blob1}" != "" ] ; then

        gzip "${blob1}"
        if [ $? -eq 0 ] ; then
            >&2 echo "  Gzipped ${blob1}" 
            blob1="${blob1}.gz"
        else
            >&2 echo "  *** FAILED to gzip ${blob1} ***" 
        fi
 
    fi

    if [ "${blob2}" != "" ] ; then
 
        gzip "${blob2}"
        if [ $? -eq 0 ] ; then
            >&2 echo "  Gzipped ${blob2}" 
            blob2="${blob2}.gz"
        else
            >&2 echo "  *** FAILED to gzip ${blob2} ***" 
        fi

    fi

fi

TFTP[edit]

sd2 can optionally send the created file to a tftp server if it is passed the -t <server> option.
Every box has the tftp command installed, a slow and old protocol but the only way to upload a file from original firmware.
This is especially useful to grab Supportdata2 from models without USB-Host like repeaters. sd2 supports tftp upload. 

if [ "${tftpserver}" != "" ] ; then

    >&2  echo "Sending files to tftp server '${tftpserver}'..."
 
    for item in "${file}" "${blob1}" "${blob2}"; do
        [ "${item}" = "" ] && continue

        tftp -p -l "${item}" -r "${item}" "${tftpserver}"

        if [ $? -eq 0 ] ; then
            >&2 echo "  Uploaded ${item}" 
        else
            >&2 echo "  *** FAILED to tftp ${item} ***" 
        fi

    done

fi

A tftpd server must be running on the passed <server>. This fails with the tftp server of dnsmasq since it is read only.
You need to adapt your freetz build to enable the Busybox applets >> Networking Utilities >> tftpd applet.
And finaly you just need to put this line in Inetd >> User defined in the freetz webinterface: 

69 dgram udp nowait root /bin/busybox tftpd -l -c /var/media/ftp/tftp

Make sure dnsmarq tftp server is swiched off and the target directory exists. For me this is the Internal-Storage of my 6490.

Mail[edit]

sd2 can optionally Email the created file to me if it is passed the -m option.
This only works if your box knows the Email credentials you entered for using Push-Mail. 

if [ "${mail}" != "" ] ; then

    >&2  echo "Mailing files to hippie2000..."

    for item in "${file}" "${blob1}" "${blob2}"; do
        [ "${item}" = "" ] && continue

        mailer -t "${hippie}" -s "${item}" -d "${item}"

        if [ $? -eq 0 ] ; then
            >&2 echo "  Mailed ${item}" 
        else
            >&2 echo "  *** FAILED to mail ${item} ***" 
        fi

    done

fi

Delete[edit]

sd2 can optionally delete the created file after uploading / mailing / listing if it's passed the -d option.
This prevents from filling the RAM during development. 

if [ "${delete}" != "" ] ; then

    >&2  echo "Deleting created files..."

    rm -f "${file}" "${blob1}" "${blob2}"

fi
