Hi again,

I would like to ask you the possible ways of logging information from the

kernel, without

the messages being intercepted from dmesg. Also please note that my

implementation uses the kprobes API, so in my probes I am atomic and
uninterrupted.

printk sends the logs to the kernel ring buffer, so dmesg will always see

them. Hence, printk-ing is not a solution.

Logging to a unix socket (i.e. /dev/log) didn't work (check "Crash when

sending a lot of messages through a unix socket" thread).

proc filesystem, I am not sure, but I believe that is not suitable for

logging information. It is more for kernel information exposing.

Any other ideas? My problem is that I log sensitive data and any

unprivileged user can run dmesg and see the sensitive logs.

Thank you in advance for your time,
Panos
