Hi,
This is probably a classic example, but I'm struggling and was hoping the
wisdom of the fine folks here could help.
I'm trying to add any missing NULL checks to a few function calls, namely:
malloc
calloc
strdup
At present, I have the following rule:
@@
expression T;
@@
T = strdup(...);
+ if (T == NULL)
+ pkg_emit_errno("strdup", __func__);
... when != (T == NULL)
when != (T != NULL)
This is the same for calloc() and malloc(). And it works OK. The problem I
have is that it's not capturing all the cases. So for example, the following
is matched:
char *foo;
char *bar = "hello";
foo = strdup(foo);
But if I have something more complicated, such as this:
struct *foo;
foo->member = strdup("hello");
Then the Cocci rule I have doesn't match -- and I can only assume at this
point that struct members aren't covered by using an "expression"
metavariable?
You might also ask why I'm using "strdup(...)" -- this is because in some
cases calls inside strup could be other function calls, such as:
strdup(say_hello("Thomas"));
... and I wasn't sure how best to handle that either, so I just went with
"..." which seems to work.
How can I better ensure that my rule covers more of my code?
TIA!

This is strange. Because struct members are quite definitely covered by
the expression metavariable. Perhaps the function that contains this code
incurs a parse error? One way to see this is to say spatch --type-c
file.c. If you don't see any type annotations in a function then there is
a problem. You can also use --parse-c instead of --type-c to get some
information about the precise problem. But the output can be verbose.
Look for the lines containing BAD.

Hi Julia,
Thank you for your reply. Attached with this email is two files:
* type-c.out -- contains the output from running with --type-c. Just for an
example, there's a function in that output: pkg_vset() which has a few
calls to strdup() which aren't being matched.
* parse-c.out -- I don't see anything in there which explains the output from
type-c.out
What should I be looking for?
Indeed -- even with the "--debug" flag, although there are lines marked as
"bad:" none of them relate to the functions I'm matching with strdup().
Thanks, Julia. Anything you can suggest is much appreciated, and if you
require any further information, do not hesitate to ask.
Kindly,
Thomas

Could you send me the original .c file, preferably cut down to show only
the error?
For --parse-c, most of the interestingoutput is on stderr.

Hi Julia,
Yes -- stderr was redirected to those files anyway.
Please see the attached .c file which just contains a sample function which
isn't being matched.
Kindly,
Thomas

For me, the attached file seems to work fine. But the function is quite
big and contains many strdups. If there is one that is not getting
matched, perhaps you could make a smaller example that illustrates the
problem.
>From the type-c output, I have the impression that it is pkg_adddep that

functions seem to have annotations on some variables. When Coccinelle
doesn't know the type, it will put /**/. But that means that it processed
the code but doesn't know the type, not that it did not process the code
at all.

There's others, but it's the same variation on the theme.

Odd. I am invoking spatch with -I repeatedly to ensure that it includes the
relevant headers.
What would you suggest I do next to try and understand why pkg_adddep() isn't
being processed? When I use --debug, I see the entire thing is marked as
"bad:" -- and although there's a hint in there about "set verbose_parsing",
I'm unsure what that means, or whether it would help.
Thanks again for your time and help, Julia.

Interesting. The .c file example I sent you was just that -- completely cut
down to just pkg_adddep() which does not work for me with the rules I
outlined.
At this point, I'm wondering if I am doing something really dumb here.

So I did this, and no matter what I do this file just isn't being parsed at
all. The smallest test-case is what I've already sent through, but that
implies there's something else going on.
I've got some bad/BAD lines you might want to look at. But at this point, the
problem is something with the environment.
Thanks again, Julia.

Sorry, I meant pkg_vset() -- there's too many moving parts! I'm sending the
entire .c file so that you might better place it in context with the debug
file I attached in my previous email. Needless to say, despite my
chopping/changing this file, it's still not working.
Thanks for your continued help, Julia.

For me they are all transformed. What is your version of spatch? What is
your command line? What is your semantic patch (you sent it before, but I
no longer have it)?

I'm invoking spatch like this:

init_defs_builtins: /usr/local/lib/coccinelle/standard.h
HANDLING: libpkg/pkg.c
Note: processing took 16.3s: libpkg/pkg.c
libpkg/pkg.c contains no transformations.
This is running atop of FreeBSD, should that somehow make any difference.
Thanks again!
Thomas

The problem for the vset function is that a pattern like
A
...
requires that there be no A along all paths leaving from the matched A.
Your code matching the first pattern is in a loop, so obviously there is
at least one path that reaches A again. So the rule doesn't match. If
you want to consider the region until A optionally occurs again, then you
can write:
A
...
?A
The ? makes it optional.

Ah. I think I understand that, Julia. If I blindly modify the strdup rule to
this:
T = strdup(...);
+ if (T == NULL)
+ pkg_emit_errno("strdup", __func__);
?... when != (T == NULL)
? when != (T != NULL)
And then run:
spatch --in-place --sp-file ~/unchecked_malloc.cocci libpkg/pkg.c
This now captures the other remaining strdup() calls which were going
undetected. However, as a side-effect of this, the matching rule is adding in
the same NULL checks for function calls which already has them; hence a
doubling-up.
I appreciate I've just blindly followed your advice; could you perhaps
elaborate (and educate me) as to the correct way to ammend this rule?
Thanks.

The ? doesn't go on the ... line. I'm rather surprised that that would
parse, even. Your line in the A position is T = strdup(...);. So you
need to put another copy of that at the end of the rule with ? in front
of it. So that it stops when it comes to that again.

spatch certainly didn't mind, and went on to apply the rule. If I've
uncovered a bug, great! :)

And now it's working just fine. Thanks ever so much for all of your help,
Julia, and your continued efforts on Coccinelle; it's a fantastic piece of
software.

I became also curious on how the discussed source code transformation can
really work. I imagine that there are still some software development challenges
left over for further considerations.
* A filter criterium like ?T = strdup(...);? was specified.
How do you think about to use a SmPL disjunction (or an advanced SmPL constraint
on a metavariable with the type ?identifier? instead)?
* Can the function call ?pkg_emit_errno? become a bit more generic by passing
a string from previously matched data?
* Would you like to check any more cases so that the technology ?data flow analysis?
will be also needed here?
Regards,
Markus

You're right. The next step I'm looking at is making my checks automatable so
that they can truly patch code properly. Right now, what I have is merely a
"best guess" placeholder which is inserted, leaving the programmer having to
go in and correct the compilation.
Consider the following rule:
T = strdup(...);
+ if (T == NULL) {
+ pkg_errno("strdup", __func__);
+ return (EPKG_FATAL);
+ }
... when != (T == NULL)
when != (T != NULL)
? T = strdup(...);
The problem is that if this rule matches, the inserted code will always be:
pkg_errno("stdup", __func__);
return (EPKG_FATAL);
That return should *not* be there if the return type of the function the code is
being inserted to is anything other than "int". Likewise, if the function
returns void, it should be "return;", or a pointer should be "NULL".
Is there a clever way of conditionally making this change?
Kindly,
Thomas

Doing something based on the type would be possible. For example, you can
have a pattern like (simplified version):
void f(...) { <...
x = foo();
+ if (!foo) return;
...> }
Choosing real error handling code that would free the previously allocated
resources is probably beyond the abilities of Coccinelle.

The answer depends on your desire how ?clever? (or sophisticated) an other approach
should become.
You could try to work with more disjunctions and rules in the semantic patch language.
This transformation might trigger a few target conflicts and further software
development challenges as you might become also aware of special needs and
corresponding advancements in technology.
How many software developers and source code reviewers care really about unused
(or ignored) return values from various function calls?

Markus
