From 6b1f16ba730d4c0cda1247568c3a1bf4fa3a2f2f Mon Sep 17 00:00:00 2001 From: Harald Freudenberger Date: Fri, 12 Apr 2019 11:04:50 +0200 Subject: [PATCH] s390/pkey: add one more argument space for debug feature entry The debug feature entries have been used with up to 5 arguents (including the pointer to the format string) but there was only space reserved for 4 arguemnts. So now the registration does reserve space for 5 times a long value. This fixes a sometime appearing weired value as the last value of an debug feature entry like this: ... pkey_sec2protkey zcrypt_send_cprb (cardnr=10 domain=12) failed with errno -2143346254 Signed-off-by: Harald Freudenberger Reported-by: Christian Rund Signed-off-by: Martin Schwidefsky --- drivers/s390/crypto/pkey_api.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/s390/crypto/pkey_api.c b/drivers/s390/crypto/pkey_api.c index 3e85d665c572..45eb0c14b880 100644 --- a/drivers/s390/crypto/pkey_api.c +++ b/drivers/s390/crypto/pkey_api.c @@ -51,7 +51,8 @@ static debug_info_t *debug_info; static void __init pkey_debug_init(void) { - debug_info = debug_register("pkey", 1, 1, 4 * sizeof(long)); + /* 5 arguments per dbf entry (including the format string ptr) */ + debug_info = debug_register("pkey", 1, 1, 5 * sizeof(long)); debug_register_view(debug_info, &debug_sprintf_view); debug_set_level(debug_info, 3); }
