Function Documentation

int df_rand_continue ( const int fuzz_on_str_len )

Tells callee whether to continue testing according to current size of generated strings not to exceed df_buf_size length.

Parameters

fuzz_on_str_len If 1, fuzzing will be controlled by generated random strings lengths

Returns: 1 when callee should continue, 0 otherwise

int df_rand_dbus_objpath_string ( gchar ** buf )

Allocates memory for pseudo-random object path string of size counted by adding 1 to size variable on every call of function to maximum size of MAXLEN. On every call pseudo-random object path string is generated into buf buffer. Warning: buf should be freed outside this module by callee of this function.

Parameters

buf	Address of pointer on buffer where generated object path string will be stored

Returns: 0 on success, -1 on error

int df_rand_dbus_signature_string ( gchar ** buf )

Allocates memory for pseudo-random signature string of size counted by adding 1 to size variable on every call of function to maximum size of MAXSIG. On every call pseudo-random signature string is generated by random access into global variable df_sig_def which contains all D-Bus signatures and copying signature into buf buffer. Warning: buf should be freed outside this module by callee of this function.

Parameters

buf	Address of pointer on buffer where generated signature string will be stored

Returns: 0 on success, -1 on error

gboolean df_rand_gboolean ( void )

Returns: Generated pseudo-random boolean value

gdouble df_rand_gdouble ( void )

Returns: Generated pseudo-random double precision floating point number

gint16 df_rand_gint16 ( void )

Returns: Generated pseudo-random 16-bit integer value

gint32 df_rand_gint32 ( void )

Returns: Generated pseudo-random 32-bit integer value

gint64 df_rand_gint64 ( void )

Returns: Generated pseudo-random 64-bit (long) integer value

guint16 df_rand_guint16 ( void )

Returns: Generated pseudo-random 16-bit unsigned integer value

guint32 df_rand_guint32 ( void )

Returns: Generated pseudo-random 32-bit unsigned integer value

guint64 df_rand_guint64 ( void )

Returns: Generated pseudo-random 64-bit (long) unsigned integer value

guint8 df_rand_guint8 ( void )

Returns: Generated pseudo-random 8-bit unsigned integer value

int df_rand_GVariant ( GVariant ** var )

Creates Gvariant containing pseudo-random string. At the beginning strings from global array df_str_def are used.

Parameters

var	Address of pointer on GVariant where new Gvariant value will be stored

Returns: 0 on success, -1 on error

void df_rand_init ( const long buf_size )

Initializes global flag variables and seeds pseudo-random numbers generators.

Parameters

buf_size Maximum buffer size for generated strings (in Bytes)

static void df_rand_random_string	(	char *	buf,
		const long	size
	)

static

Generates pseudo-random string of size size.

Parameters

buf	Pointer on buffer where generated string will be stored
size	Size of buffer

int df_rand_string ( gchar ** buf )

Allocates memory for pseudo-random string of size counted by adding generated pseudo-random number from interval <0, CHAR_MAX> to df_str_len (this mechanism is responsible for generating bigger strings by every call of df_rand_string()). Then pseudo-random string is generated and stored in buf. At the beginning strings from global array df_str_def are used. Warning: buf should be freed outside this module by callee of this function.

Parameters

buf	Address of pointer on buffer where generated string will be stored

Returns: 0 on success, -1 on error

int df_rand_unixFD ( void )

Returns: Generated pseudo-random FD number from interval <-1, INT_MAX)

double drand ( void )

inline

Returns: Generated pseudo-random double precision floating point number from interval <0, 1>

Variable Documentation

static

Maximum buffer size for generated strings (in Bytes)

unsigned df_index_str

static

Index into df_str_def array for function df_rand_string()

unsigned df_index_var

static

Index into df_str_def array for function df_rand_GVariant()

unsigned int df_num_fuzz_counter

static

static

Array of signature definitions, which will be send to tested process if it has any signature parameters.

const char* df_str_def[]

static

Initial value:

= {
    "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA",
    
    NULL
}

Array of strings, which will be send to tested process if it has any string parameters. Feel free to include any strings here (only valid UTF-8). Array must be terminated by NULL string.
