[PATCH] selftest: Fix UB of getline due to missing var init

[Chris Gellermann]

Clone3_set_tid uses getline(&line, &len, f) in a loop to read the
child's process status. The code expects that getline allocates the
buffer for the line on the first loop iteration. For this, glibc[1]
requires char *line to be set to NULL:

> ssize_t getline(char **restrict lineptr, ...)
> If *lineptr is set to NULL before the call, then getline() will
> allocate a buffer for storing the line.

However, char *line is only declared, leading to an undefined
initialization value. Fix this by properly initializing it to NULL.

Same issue fixed in mlock-random-test.

You'll need separate commits for each I think? That'd at least make life
easier. You can send them as a series.

Strange this didn't result in noticeable bugs but maybe perceived as flakes

Does the test crash?  If not, how come?  Luck?

The two affected files are testing significantly different parts of the

And these were separated by three years.

So can you please split this into a two-patch series?  And I suggest
you add "Cc: <stable@vger.kernel.org>" to each one.  Please retain David's
ack on both.

Thanks.

[PATCH v2 1/2] selftests/clone3: Fix wild pointer access of getline due to missing init

[Chris Gellermann]

Clone3_set_tid uses getline(&line, ...) in a loop to read the child's
process status. The code expects that getline allocates the buffer for
the line on the first loop iteration. According to the Open Group
Spec[1], char *line has to be null pointer for this:

> ssize_t getline(char **restrict lineptr, ...);
> If *lineptr is a null pointer or if the object pointed to by *lineptr
> is of insufficient size, an object shall be allocated as if by
malloc()
> or the object shall be reallocated as if by realloc()[...].

However, char *line is only declared, leading to an undefined value
that is potentially non-null. In an example run with Musl v1.2.6, the
realloc call[2] of getdelim, which implements getline, triggers a
segfault:

./run_kselftest.sh --test clone3:clone3_set_tid
[ 1366.165898] kselftest: Running tests in clone3

[ 1367.805314]  t0 : 0x0000003fbf63d000
...

Looking at the realloc implementation, Musl mallocs for a null pointer
memory. But for a non-null pointer, it assumes it's passed a valid
pointer to the heap and tries to access its meta-data. This leads to the
segfault we see:

void *realloc(void *p, size_t n)
{
        if (!p) return malloc(n);
        if (size_overflows(n)) return 0;

        struct meta *g = get_meta(p);
        ...
}

Fix this by properly initializing the line pointer to NULL.

[PATCH v2 2/2] selftests/mm: Fix potential wild pointer access of getline due to missing init

[Chris Gellermann]

This is another occurrence of using getline where the code assumes that
getline allocates memory to store the line, but the pointer passed to
it is uninitialized and potentially a non-null pointer. This
violates the Open Group Spec[1] and caused a segfault in a similar
situation in selftest/clone3/clone3_set_tid. Fix it by initializing the
line pointer to NULL.

The issue has been found by simply grepping through the selftest code
after running into the issue in clone3_set_tid. Whether it segfaults in
its current state is unknown to me. But it's good to be addressed due to
defensive reasons.

[PATCH v2 2/2] selftests/mm: Fix potential wild pointer access of getline due to missing init

[Chris Gellermann]

This is another occurrence of using getline where the code assumes that
getline allocates memory to store the line, but the pointer passed to
it is uninitialized and potentially a non-null pointer. This
violates the Open Group Spec[1] and caused a segfault in a similar
situation in selftest/clone3/clone3_set_tid. Fix it by initializing the
line pointer to NULL.

The issue has been found by simply grepping through the selftest code
after running into the issue in clone3_set_tid. Whether it segfaults in
its current state is unknown to me. But it's good to be addressed due to
defensive reasons.

Have these been picked up in the meantime?

For future reference: don't send v2 in reply to v1, as new revisions might just
get buried in other discussions that way.

Yup, I added the v2 series to mm-hotfixes-unstable on Jul 22.
