+Subject: [PATCH 001/104] file_util.c: fix possible bad memory access in
+ file_read_line_alloc()
+
+In the case of a zero length string being returned by fgets(), the condition
+checking for a trailing new line would perform a bad memory access outside
+of `buf`. This might happen when line with a leading null byte is read.
+
+Avoid this case by checking that the string has a length of at least one
+byte. Also change the unsigned int types to size_t to store length values
+while we're at it.
+
+Upstream-Status: Backport [https://github.com/ndmsystems/opkg/commit/8b45a3c4cab95382beea1ecdddeb2e4a9ed14aba]
