Vakul Garg 52ea992cfa net/tls: Set count of SG entries if sk_alloc_sg returns -ENOSPC ... tls_sw_sendmsg() allocates plaintext and encrypted SG entries using function sk_alloc_sg(). In case the number of SG entries hit MAX_SKB_FRAGS, sk_alloc_sg() returns -ENOSPC and sets the variable for current SG index to '0'. This leads to calling of function tls_push_record() with 'sg_encrypted_num_elem = 0' and later causes kernel crash. To fix this, set the number of SG elements to the number of elements in plaintext/encrypted SG arrays in case sk_alloc_sg() returns -ENOSPC.
