Setting process capabilities in Petalinux



I have written an application in C++, compiled with SDK tools, in which I use function mlockall() in order to prevent all the memory used by the process from being paged to disk. To lock any amount of memory, the process must be privileged or have the capability CAP_IPC_LOCK set.


I want to start the process from a non-root user's shell. Thus, I have to set the CAP_IPC_LOCK capability. In other Linux, e.g. Ubuntu, capabilities can be set from the shell with command "setcap", but I have not found this command in Petalinux.


Do you have any idea of how to set capability CAP_IPC_LOCK in Petalinux?


Best regards,

Juan Ángel
