Subject: [PATCH] seccomp: add kill() to the syscall whitelist
|
|
|
c40251 |
|
|
|
c40251 |
The kill() syscall is triggered with the following command:
|
|
|
c40251 |
|
|
|
c40251 |
# qemu -sandbox on -monitor stdio \
|
|
|
c40251 |
-device intel-hda -device hda-duplex -vnc :0
|
|
|
c40251 |
|
|
|
c40251 |
The resulting syslog/audit message:
|
|
|
c40251 |
|
|
|
c40251 |
# ausearch -m SECCOMP
|
|
|
