I provided this backport patch to #openwrt on freenode last week. I am glad it was included in trunk. Two important clarifications: 1. The original poster applies his patch to kernel 3.3.8 (it seems) yet the interface that makes use of get_cycles() in seeding the random pool wasn't introduced until 3.6. The patch on pre-3.6 kernels effectively does nothing entropy-wise. Without more comprehensive backports, there is no similar simple solution for Attitude. 2. You aren't going to see /proc/sys/kernel/random/entropy_avail affected by this patch because the machine/boot specific seeding does not credit the entropy count. --mancha _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
