When eciadsl-synch from eciadsl-0.10 end on timeout, the semaphore is not
removed and and a new one is created at the next synch attempt.
I saw this three days ago by adding some debug info to my synch script:
I do like this
while [ $CNT -le 5 -a $RET -ne 0 ]; do
msg "$MODEM Synch attempt #$CNT"
cat /proc/sysvipc/sem > /tmp/synch-$CNT.log
/usr/$BPATH/eciadsl-synch -v 0x$VID2 0x$PID2 /var/ipcop/eciadsl/synch.bin
>> /tmp/synch-$CNT.log
RET=$?
CNT=$(expr $CNT + 1)
/bin/sleep 2
done
Result from the cat /proc/sysvipc/sem look like this
key semid perms nsems uid gid cuid cgid otime

All semaphores but the first one were created and not removed by
eciadsl-synch-0.10 (I have removed one or two more of them playing with
ipcrm at the middle of the list).
Next I try to understand and add some debug info on the code to see what
happen.
By mistake, I copy the eciadsl-synch binary from
eciadsl-usermode-0.10-nortek-alpha. So I did not saw my debug message, but I
discover 0.10-nortek-alpha eciadsl-synch work with standard version modem,
the synch process is not the same because it never fail on timeout , so
synch is quicker because there is no time loose before retrying to synch
again.
Because it did not fall on timout as standard 0.10 version, I am not capable
to reproduce the problem but the same leak with semaphore creation should
exist if a timeout occur.
