Hello Hoernchen, Jenkins Builder, laforge, osmith,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/docker-playground/+/36836?usp=email
to look at the new patch set (#2).
Change subject: ttcn3-docker-run.sh: Fix dumpcap failing to access /data inside
docker
......................................................................
ttcn3-docker-run.sh: Fix dumpcap failing to access /data inside docker
In docker, the /data dir is mapped to $VOL_BASE_DIR, which is created by
docker-playground.git jenkins-common.sh, hence as the user running
jenkins.sh in the host system.
As a result, when the dir is mapped to /data, inside the container it
will have the UID:GID of the outter user, not the one inside docker.
Before this patch, if a ttcn3 container was started in jenkins.sh with
--cap-add=NET_ADMIN, then osmo-ttcn3-hacks.git/ttcn3-tcpdump-start.sh
would select dumpcap instead of tcpdump, to attempt to record a pcap
file to /data/$testcase.pcap.
Due to some unknown way of dropping privileges done by dumpcap though,
it was unable to open the /data/$testcase.pcap due to /data being owned
to another user (tcpdump doesn't have this problem).
This patch fixes the above scenario by making sure /data is chowned to
the user running stuff inside docker. This is already kinda expected
since there's a fix_perms() script in jenkins-common.sh reverting files
created during the test so that they can be accessible by outter user
once everything is finished.
