The patch titled ansi_cprng: zero out key data on exit has been removed from the -mm tree. Its filename was ansi_cprng-zero-out-key-data-on-exit.patch This patch was dropped because it is obsolete The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: ansi_cprng: zero out key data on exit From: Neil Horman <nhorman@xxxxxxxxxxxxx> Its been mentioned to me a few times that the ansi_cprng doesn't zero out its data when a context is freed. Given that we store key, and other seed data in that structure, I think its probably a good idea that we zero it out. This patch does that.
