[PATCH] net/appletalk: Fix kernel memory disclosure

ipddp_route structs contain alignment padding so kernel heap memory is leaked when they are copied to user space in ipddp_ioctl(SIOCFINDIPDDPRT). Change kmalloc() to kzalloc() to clear that memory. Signed-off-by: Vlad Tsyrklevich --- drivers/net/appletalk/ipddp.c | 2 +- 1 file changed, 1

[PATCH] drivers/ptp: Fix kernel memory disclosure

The reserved field precise_offset->rsv is not cleared before being copied to user space, leaking kernel stack memory. Clear the struct before it's copied. Signed-off-by: Vlad Tsyrklevich --- drivers/ptp/ptp_chardev.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/ptp/ptp_c
