I am writing software that will execute on a customized Debian Linux and also on an embedded POSIX system. On the embedded system, I execute the code as root. On the Debian system, I execute the code as my non-root user account. This is the normal usage of the application.
I am using ftok(), shmget(), shmat() to obtain a small quantity of shared memory for the application. As root, the shmat() function succeeds on the embedded system. However, on the Debian system the shmat() function returns -1 with an error code of EACCES, indicating permission denied. The embedded system does not have shm_open(), otherwise I would use that. /proc/config.gz reveals that SYSVIPC is indeed compiled into the Linux kernel of the Debian system. How can I diagnose the program on the Debian system? I read on the Internet that this may have something to do with Linux Capabilities settings? -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
