+Subject: libext2fs: fix potential buffer overflow in closefs()
+
+The bug fix in f66e6ce4446: "libext2fs: avoid buffer overflow if
+s_first_meta_bg is too big" had a typo in the fix for
+ext2fs_closefs(). In practice most of the security exposure was from
+the openfs path, since this meant if there was a carefully crafted
+file system, buffer overrun would be triggered when the file system was
+opened.
+
+However, if corrupted file system didn't trip over some corruption
+check, and then the file system was modified via tune2fs or debugfs,
+such that the superblock was marked dirty and then written out via the
+closefs() path, it's possible that the buffer overrun could be
+triggered when the file system is closed.
+
+Also clear up a signed vs unsigned warning while we're at it.
+
+Thanks to Nick Kralevich <nnk@google.com> for asking me to look at
+compiler warning in the code in question, which led me to notice the
+bug in f66e6ce4446.
