From 7fc5180d0f4af5260c67ed6d82ff1cba8fb9113c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 3 Sep 2015 08:41:33 +1000 Subject: [PATCH] libxfs: verifier should set buffer error when da block has a bad magic number If xfs_da3_node_read_verify() doesn't recognize the magic number of a buffer it's just read, set the buffer error to -EFSCORRUPTED so that the error can be sent up to userspace. Without this patch we'll notice the bad magic eventually while trying to traverse or change the block, but we really ought to fail early in the verifier. Signed-off-by: Darrick J.
