This series fixes all the information leaks in crypto_user reporting, removes some redundant reporting functions, and makes some changes to reduce the chance of similar information leaks in the future. Patch 2 is based on a patch already sent by Corentin Labbe, but it was incomplete so I fixed it. Corentin Labbe (1): crypto: crypto_user_stat - Zeroize whole structure given to user space Eric Biggers (3): crypto: crypto_user - fix leaking uninitialized memory to userspace crypto: crypto_user - remove redundant reporting functions crypto: crypto_user - clean up report structure copying crypto/ablkcipher.c | 32 ++++------ crypto/acompress.c | 10 +--- crypto/aead.c | 14 ++--- crypto/ahash.c | 12 ++-- crypto/akcipher.c | 11 ++-- crypto/blkcipher.c | 16 ++--- crypto/crypto_user_base.c | 95 +++++------------------------ crypto/crypto_user_stat.c | 123 ++++++++++++++------------------------ crypto/kpp.c | 10 +--- crypto/rng.c | 12 ++-- crypto/scompress.c | 11 ++-- crypto/shash.c | 12 ++-- crypto/skcipher.c | 15 ++--- 13 files changed, 116 insertions(+), 257 deletions(-) -- 2.19.1
