For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause Signed-off-by: Kees Cook --- crypto/algapi.c | 4 ++-- crypto/authenc.c | 1 + crypto/authencesn.c | 1 + crypto/cbc.c | 1 + crypto/chainiv.c | 1 + crypto/cmac.c | 1 + crypto/cts.c | 1 + crypto/ecb.c | 1 + crypto/eseqiv.c | 1 + crypto/hmac.c | 1 + crypto/lrw.c | 1 + crypto/pcbc.c | 1 + crypto/seqiv.c | 1 + crypto/vmac.c | 1 + crypto/xcbc.c | 1 + crypto/xts.c | 1 + 16 files changed, 17 insertions(+), 2 deletions(-) diff --git a/crypto/algapi.c b/crypto/algapi.c index e8d3a7dca8c4..71a8143e23b1 100644 --- a/crypto/algapi.c +++ b/crypto/algapi.c @@ -509,8 +509,8 @@ static struct crypto_template *__crypto_lookup_template(const char *name) struct crypto_template *crypto_lookup_template(const char *name) { - return try_then_request_module(__crypto_lookup_template(name), "%s", - name);
