If I understand correctly you want to store an "int" value internally to
a custom BIO.

Custom BIOs can associate an arbitrary data structure with the BIO
object and store whatever they like in it using the BIO_get_data() and
BIO_set_data() functions.

For example:

typedef struct {
int num;
} XYZ_PRIVATE_DATA;

static int XYZ_mem_new(BIO *bio)
{
XYZ_PRIVATE_DATA *data = OPENSSL_zalloc(sizeof(*data));

if (data == NULL)
return 0;

/* Store whatever you like in num */
data->num = 5;
BIO_set_data(bio, data);
}

static int XYZ_mem_free(BIO *bio)
{
XYZ_PRIVATE_DATA *data = BIO_get_data(bio);

OPENSSL_free(data);
BIO_set_data(bio, NULL);
}

static int XYZ_mem_read(BIO *bio, char *out, int outl)
{
XYZ_PRIVATE_DATA *data = BIO_get_data(bio);

/* Do the read operation and use data->num as required */
}

Re: set/get utilities are not available to access variable 'num' of structure bio_st (Matt Caswell)

2020-11-23 Thread Narayana, Sunil Kumar 
Hi Matt,
   We are using  MEM type BIO. similar to the openssl library 
‘BIO_TYPE_MEM ‘ we have an internal type defined like ex:- ‘BIO_TYPE_XYZ_MEM’  
and all other mem utilities are internally defined.
Like XYZ_mem_new/XYZ_mem_read … etc  these utilities are accessing the bio_st 
variable ‘num’.
please suggest set/get utilities to handle this scenario.

Regards,
Sunil

Hi ,
We are porting our Application from openssl 1.0.1 to openssl 3.0. In related to 
this activity we require to access the variable 'num' of structure bio_st.
In older versions the variable was accessed to set and get value using pointer 
operator (bi->num ).
Since this is not allowed in 3.0 we are looking for the Get/Set utilities 
similar to other member (BIO_set_flags/ BIO_get_flags)

Is this not supported in 3.0 ? If yes, Please guide the proper alternatives.

Regards,
Sunil

What kind of BIO are you using? Different BIOs may provide different
mechanisms to get hold of this value. For example a number of file
descriptor based BIOs provide BIO_get_fd().

set/get utilities are not available to access variable 'num' of structure bio_st

2020-11-20 Thread Narayana, Sunil Kumar 
Hi ,
We are porting our Application from  openssl 1.0.1 to openssl 
3.0. In related to this activity we require to access the variable 'num' of 
structure bio_st.
In older versions the variable was accessed to set and get value using pointer 
operator (bi->num ).
Since this is not allowed in 3.0 we are looking for the Get/Set utilities 
similar to other member (BIO_set_flags/ BIO_get_flags)

Is this not supported in 3.0 ? If yes, Please guide the proper alternatives.

Sunil
