seccomp: add kill() to the syscall whitelist
|
|
|
0a122b |
|
|
|
0a122b |
The kill() syscall is triggered with the following command:
|
|
|
0a122b |
|
|
|
0a122b |
# qemu -sandbox on -monitor stdio \
|
|
|
0a122b |
-device intel-hda -device hda-duplex -vnc :0
|
|
|
0a122b |
|
|
|
0a122b |
The resulting syslog/audit message:
|
|
|
0a122b |
|
|
|
0a122b |
# ausearch -m SECCOMP
|
|
