back to article Linus Torvalds lauds fuzzing for improving Linux security

Linus Torvalds release notification for Linux 4.14's fifth release candidate contains an interesting aside: the Linux Lord says fuzzing is making a big difference to the open source operating system. Torvalds' announcement says Linux kernel 4.14 is coming along nicely, with this week's release candidate pleasingly small and “ …

    Nice.

    I can remember being a teen/school kid and wondering why they did not test those bugged games this way before poor teen/school kid me had to buy them to find it bugged and broken. ;)

    But of cause, the search space can be massive, so not always successful. Though it should find simple bugs that are often overlooked, such as illegal characters in the text fields (or in this case API calls?).

    Any extra tools for getting jobs done are nice.

      I remember Match Day (on the Comodore 64) - used to see the top half of the goalie halfway down the pitch rather often - hard to overlook that bug.

    "A new word for what in the 1960s we called "testing"."

    Rather a new tool called fuzzing to use in something still called testing, according to the Wiki anyway.

    "Fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program.".

      Is fuzzing really new?

      We used to use the librarian and scripts to attack anything in libraries with bucket load of made up data to see what things fell over.

      Alas GUIs caused problems for a few years until things stabilised enough to attack them sensibly.

      So the only really new thing is...

      the marketing/name?

      Like "cloud" but for testing. ;)

      A new trendy name does not mean a new technique.

      “The fuzzing of programs with random inputs dates back to the 1950s”

    By the way

    Asking Dimitry Yukov if he believes in fairies and Santa Claus is not being mean about Unicorns. A bit sceptic perhaps. Then again searching for "sceptic" I get this:

    "a person inclined to question or doubt accepted opinions."

    "an ancient or modern philosopher who denies the possibility of knowledge, or even rational belief, in some sphere."

    And searching for "skeptic" I get this:

    "a person who questions the validity or authenticity of something purporting to be factual. 2. a person who maintains a doubting attitude, as toward values, plans, statements, or the character of others. 3. a person who doubts the truth of a religion, especially Christianity, or of important elements of it.".

    (Wow, especially Christianity).

    This would all make me very sceptical was it not for my spellchecker who demands me to be skeptical.

    Quite frankly I think Linus should have gone with some nice swear word for less confusion and not risking being considered mean and breaking hearts.

    (And once again I realize I am retired).

    Unicorns

    "At least you didn't say anything mean about Unicorns."

    I suspect that his views on Unicorns may be similar to Father Jack's views on tea cups.

    Well if he doesn't like it why doesn't he write it himself?

      Sometimes he does

      When he didn't like his choices of software management he took a few weeks off and wrote his own. It is called GIT and is very popular.

    @AC

    I don't think you got what he was writing about, in other words, you did not read it.
