Author: jhb Date: Wed Apr 1 17:09:21 2020 New Revision: 359524 URL: https://svnweb.freebsd.org/changeset/base/359524 Log: Set crp_ilen for crypto requests. Assertions in crypto_dispatch() depend on this value being set to verify that payload and AAD regions are in bounds. Also, requests that use a single kernel buffer rely on this to know how long the buffer is for bus_dma, etc. Reported by: kp Modified: head/sys/kgssapi/krb5/kcrypto_aes.c Modified: head/sys/kgssapi/krb5/kcrypto_aes.c ============================================================================== --- head/sys/kgssapi/krb5/kcrypto_aes.c Wed Apr 1 17:08:55 2020 (r359523) +++ head/sys/kgssapi/krb5/kcrypto_aes.c Wed Apr 1 17:09:21 2020 (r359524) @@ -158,6 +158,7 @@ aes_encrypt_1(const struct krb5_key_state *ks, int buf crp->crp_buf_type = buftype; crp->crp_buf = buf; + crp->crp_ilen = skip + len; crp->crp_opaque = as; crp->crp_callback = aes_crypto_cb; @@ -329,6 +330,7 @@ aes_checksum(const struct krb5_key_state *ks, int usag crp->crp_flags = CRYPTO_F_CBIFSYNC; crp->crp_buf_type = CRYPTO_BUF_MBUF; crp->crp_mbuf = inout; + crp->crp_ilen = skip + inlen + 12; crp->crp_opaque = as; crp->crp_callback = aes_crypto_cb;
