[PATCH v2] net: rxrpc: Replace time_t with time64_t

by Ksenija Stanojevic

Replace all instances of time_t with time64_t i.e. change the type used for representing time from 32-bit to 64-bit. All 32-bit kernels to date use a signed 32-bit time_t type, which can only represent time until January 2038. The patch also changes the function get_seconds() that returns a 32-bit integer to ktime_get_seconds() that returns seconds as 64-bit integer and it uses monotonic instead of real time clock. Field expiry is changed to u64 in struct rxrpc_key_data_v1 and struct rxkad_key and to time64_t in key_preparsed_payload. This change is safe since field expiry is used only in this driver. Signed-off-by: Ksenija Stanojevic <ksenija.stanojevic(a)gmail.com> --- Changes in v2: - change the type of field expiry. - modify the assignement of field put_time. - modify the assignement of variable issue. include/keys/rxrpc-type.h | 4 ++-- include/linux/key-type.h | 2 +- net/rxrpc/ar-connection.c | 4 ++-- net/rxrpc/ar-internal.h | 6 +++--- net/rxrpc/ar-key.c | 10 +++++----- net/rxrpc/ar-transport.c | 4 ++-- net/rxrpc/rxkad.c | 15 ++++++++------- 7 files changed, 23 insertions(+), 22 deletions(-) diff --git a/include/keys/rxrpc-type.h b/include/keys/rxrpc-type.h index fc48754..f13b2cb 100644 --- a/include/keys/rxrpc-type.h +++ b/include/keys/rxrpc-type.h @@ -27,7 +27,7 @@ extern struct key *rxrpc_get_null_key(const char *);
