From b51bce942023325e727ca4225252d06c49d8f2b7 Mon Sep 17 00:00:00 2001 From: Rich Salz Date: Tue, 25 Aug 2015 13:25:58 -0400 Subject: Add and use OPENSSL_zalloc There are many places (nearly 50) where we malloc and then memset. Add an OPENSSL_zalloc routine to encapsulate that. (Missed one conversion; thanks Richard) Also fixes GH328 Reviewed-by: Richard Levitte --- crypto/asn1/ameth_lib.c | 5 ++--- crypto/asn1/tasn_new.c | 6 ++---- crypto/asn1/x_pkey.c | 3 +-- crypto/bio/bss_acpt.c | 4 +--- crypto/bio/bss_conn.c | 9 +-------- crypto/bio/bss_dgram.c | 19 ++++++------------- crypto/bn/bn_blind.c | 3 +-- crypto/comp/c_zlib.c | 4 +--- crypto/comp/comp_lib.c | 3 +-- crypto/dso/dso_lib.c | 3 +-- crypto/dso/dso_win32.c | 3 +-- crypto/ec/ecp_nistp224.c | 11 ++++------- crypto/ec/ecp_nistp521.c | 9 +++------ crypto/engine/eng_cryptodev.c | 3 +-- crypto/engine/eng_dyn.c | 3 +-- crypto/engine/eng_lib.c | 3 +-- crypto/evp/evp_enc.c | 3 +-- crypto/evp/pmeth_lib.c | 5 +---- crypto/mem.c | 15 +++++++++++---- crypto/pqueue/pqueue.c | 5 +---- crypto/rsa/rsa_lib.c | 2 +- crypto/rsa/rsa_pk1.c | 3 +-- crypto/sec_mem.c | 9 +++------ crypto/store/str_lib.c | 4 +--- crypto/store/str_mem.c | 3 +-- crypto/store/str_meth.c | 6 ++---- crypto/ts/ts_rsp_sign.c | 3 +-- crypto/ts/ts_verify_ctx.c | 6 ++---- crypto/ui/ui_lib.c | 6 ++---- crypto/x509/x509_vfy.c | 3 +-- crypto/x509/x509_vpm.c | 14 ++------------ crypto/x509v3/pcy_tree.c | 17 +++++------------ 32 files changed, 64 insertions(+), 131 deletions(-) (limited to 'crypto') diff --git a/crypto/asn1/ameth_lib.c b/crypto/asn1/ameth_lib.c index 8060c18b19..155de83aaa 100644 --- a/crypto/asn1/ameth_lib.c +++ b/crypto/asn1/ameth_lib.c @@ -283,12 +283,11 @@ const EVP_PKEY_ASN1_METHOD *EVP_PKEY_get0_asn1(EVP_PKEY *pkey) EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_new(int id, int flags, const char *pem_str, const char *info) { - EVP_PKEY_ASN1_METHOD *ameth;
