The patch titled Subject: sysctl: fix null checking in bin_dn_node_address() has been removed from the -mm tree. Its filename was sysctl-fix-null-checking-in-bin_dn_node_address.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Xi Wang <xi.wang@xxxxxxxxx> Subject: sysctl: fix null checking in bin_dn_node_address() The null check of `strchr() + 1' is broken, which is always non-null, leading to OOB read. Instead, check the result of strchr(). Signed-off-by: Xi Wang <xi.wang@xxxxxxxxx> Cc: "Eric W.
