-Subject: xtables-restore: fix for --noflush and empty lines
-
-Lookahead buffer used for cache requirements estimate in restore
---noflush separates individual lines with nul-chars. Two consecutive
-nul-chars are interpreted as end of buffer and remaining buffer content
-is skipped.
-
-Sadly, reading an empty line (i.e., one containing a newline character
-only) caused double nul-chars to appear in buffer as well, leading to
-premature stop when reading cached lines from buffer.
-
-To fix that, make use of xtables_restore_parse_line() skipping empty
-lines without calling strtok() and just leave the newline character in
-place. A more intuitive approach, namely skipping empty lines while
-buffering, is deliberately not chosen as that would cause wrong values
-in 'line' variable.
-
-Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1400
-Fixes: 09cb517949e69 ("xtables-restore: Improve performance of --noflush operation")
