...he problems I am seeing. If your are interested my chan_sebi 1.4 to 1.6 patch is at http://www.mycrofters.com/sites/default/files/chan_sebi.diff . The USB modem is a Huawei E169G.

In the example decoder it writes data in varying lengths to stdout, is it possible to alter the decoder to write the same length data to stdout every time? Rather, how would you alter the decoder to do that. It seems to be writing everything from 512 to 4096 bytes each time and i cant really see why this is and how to change it. <p><p>--- >8 ---- List archives:

Hello, This series introduces a way to allow devices to contribute to initial system randomness after a certain delay. Specifically, the virtio-rng device can contribute initial randomness only after a successful probe(). A delayed workqueue item is queued in the system queue to fetch this randomness if the device indicates it's capable of contributing only after a delay, via the new

v3: - Kees Cook pointed out a weird side-effect: devices which have ->init() registered get their randomness added to the system each time they're switched in, but devices that don't have the init callback don't contribute to system randomness more than once. The weirdness is resolved here by using the randomness each time hwrng_init() is attempted, irrespective of
