syscall - "comm" field truncated

Hello, Sometimes audit of "execve" syscall generates events with truncated "comm" values, for example: type=SYSCALL msg=audit(1459950426.152:1097081): arch=c000003e syscall=59 success=yes exit=0 a0=35bae3e a1=1bc0cf0 a2=2b09280 a3=58c items=2 ppid=2183 pid=26566 auid=4294967295 uid=1001 gid=1001 euid=1001 suid=1001 fsuid=1001 egid=1001 sgid=1001 fsgid=1001 tty=(none) ses=4294967295 comm="gnome-calculato" exe="/usr/bin/gnome-calculator" Why "comm" is "gnome-calculato" and not "/usr/bin/gnome-calculator" ? Same for Firefiox: type=SYSCALL msg=audit(1459950158.667:1092149): arch=c000003e syscall=59 success=yes exit=0 a0=7f913ed1ddf0 a1=7f9144819be0 a2=7f9173f14400 a3=786f666572696600 items=2 ppid=26165 pid=26247 auid=4294967295 uid=1001 gid=1001 euid=1001 suid=1001 fsuid=1001 egid=1001 sgid=1001 fsgid=1001 tty=(none) ses=4294967295 comm="plugin-containe" exe="/usr/lib/firefox/plugin-container" comm is "plugin-containe" and not "plugin-container". Audit version is 2.4.2-1ubuntu1. -Lev
