In tomoyo_flush(), head->r.w[0] holds pointer to string data to be printed. But head->r.w[0] was updated only when the string data was partially printed (because head->r.w[0] will be updated by head->r.w[1] later if completely printed). However, regarding /sys/kernel/security/tomoyo/query , an additional '\0' is printed after the string data was completely printed. But if free space for read buffer became 0 before printing the additional '\0', tomoyo_flush() was returning without updating head->r.w[0]. As a result, tomoyo_flush() forever reprints already printed string data. Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Signed-off-by: James Morris <jmorris@namei.org> |
