Subject: Re: IRQF_SAMPLE_RANDOM question...
Date: Tue, 7 Apr 2009 14:39:05 -0700 [thread overview]
Message-ID: <a24804730904071439g4cc1779bi1ebaf814d370708c@mail.gmail.com> (raw)

1. Are there any new add_*_randomness() functions that could be added?
Some userspace daemons like EGD (running as root) feed random system
info (e.g. vmstat) into /dev/random. But how many Linux distros
actually run entropy-gathering daemons by default? Would /dev/random
be more secure if entropy-gathering daemons were replaced with new
kernel functions like add_vmstat_randomness() or add_ps_randomness()?
2. Are there any other functions that could be calling the existing
add_*_randomness() functions? Currently:
* add_input_randomness() is called from input_event().
* add_interrupt_randomess() is called from handle_IRQ_event() if
IRQF_SAMPLE_RANDOM is set.
* add_disk_randomness() is called from blk_end_io() and __blk_end_request().
