rlenferink opened a new issue, #658: URL: https://github.com/apache/celix/issues/658
The pubsub_zmq tests fail (SEGV) when running within a container. This is due to the user in the container possibly being the root user (`uid` = 0), which makes this check succeed: https://github.com/apache/celix/blob/e7aee1259a4c61463be8fcfa5dd4612a3a756192/bundles/pubsub/pubsub_admin_zmq/src/pubsub_zmq_topic_receiver.c#L643-L649 The `gotPermission` is later on used to determine whether the scheduling priority can be set: https://github.com/apache/celix/blob/e7aee1259a4c61463be8fcfa5dd4612a3a756192/bundles/pubsub/pubsub_admin_zmq/src/pubsub_zmq_topic_receiver.c#L655 When this is called with the user `root` within a container (`uid` 0), but the user outside the container being a rootless user, the tests segfault (unable to call `pthread_setschedparam`). This is the line where libzmq in the end crashes: https://github.com/zeromq/libzmq/blob/4097855ddaaa65ed7b5e8cb86d143842a594eebd/src/thread.cpp#L345 libzmq doesn't handle this too nicely and I am not sure whether this can be solved. I tried with the suggest `libcap` and after that simply falling back to using the `capsh` command, but there the `cap_sys_nice` can be set: ```bash root@fedora:/home/rlenferink/workspace/asf/celix/celix-container# capsh --print Current: =ep Bounding set =cap_chown,cap_dac_override,cap_dac_read_search,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_linux_immutable,cap_net_bind_service,cap_net_broadcast,cap_net_admin,cap_net_raw,cap_ipc_lock,cap_ipc_owner,cap_sys_module,cap_sys_rawio,cap_sys_chroot,cap_sys_ptrace,cap_sys_pacct,cap_sys_admin,cap_sys_boot,cap_sys_nice,cap_sys_resource,cap_sys_time,cap_sys_tty_config,cap_mknod,cap_lease,cap_audit_write,cap_audit_control,cap_setfcap,cap_mac_override,cap_mac_admin,cap_syslog,cap_wake_alarm,cap_block_suspend,cap_audit_read,cap_perfmon,cap_bpf,cap_checkpoint_restore ``` Any suggestions to solve this? -- This is an automated message from the Apache Git Service.
