Hi, All:
   When i use the cryptsetup command to set the aes-xts-plain
encryption, the system will entry the crypt() routine which defined in
the xts.c file. I find the routine will call two important routines:
tw and fn. I think the fn will point to the aes_encrypt/decrypt
routine. But i want to know which routine the tw will point to for
aes-xts-plain encryption? and where i can find its source code? I put
the segment where the tw routine will be called in the bellow.

        wsrc = w->src.virt.addr;
        wdst = w->dst.virt.addr;

        /* calculate first value of T */
        tw(crypto_cipher_tfm(ctx->tweak), w->iv, w->iv);

        goto first;

        for (;;) {
                do {


Thanks all!

Best Regards
