Hi Kevin & Bruce, When running sparse on the sunrpc code, I'm seeing the following error message: "net/sunrpc/auth_gss/gss_krb5_crypto.c:603:52: error: bad constant expression" This boils down to the line: u8 data[crypto_blkcipher_blocksize(cipher) * 2]; which is using a GNU Cc-ism in order to do dynamic allocation on the stack. This is not acceptable in kernel code, and really needs to be changed. How should we move forward with this? Is there an upper limit on the value of crypto_blkcipher_blocksize(cipher) that we can use?
