From 43dcc86a137b5c1192eca67c345b73a9ccc4dccb Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 15 Jun 2016 22:41:56 +0200 Subject: [PATCH] sd-bus: make sure bus_map_all_properties() handle booleans right sd-bus generally exposes bools as "int" instead of "bool" in the public API. This is relevant when unmarshaling booleans, as the relevant functions expect an int* pointer and no bool* pointer. Since sizeof(bool) is not necessarily the same as sizeof(int) this is problematic and might result in memory corruption. Let's fix this, and make sure bus_map_all_properties() handles booleans as ints, as the rest of sd-bus, and make all users of it expect the right thing. --- src/login/loginctl.c | 4 ++-- src/shared/bus-util.c | 2 +- src/timedate/timedatectl.c | 8 ++++---- 3 files changed, 7 insertions(+), 7 deletions(-) diff --git a/src/login/loginctl.c b/src/login/loginctl.c index 0fc2720..0fc33cf 100644 --- a/src/login/loginctl.c +++ b/src/login/loginctl.c @@ -290,7 +290,7 @@ typedef struct SessionStatusInfo { char *seat; char *tty; char *display; - bool remote; + int remote; char *remote_host; char *remote_user; char *service; @@ -304,7 +304,7 @@ typedef struct SessionStatusInfo { typedef struct UserStatusInfo { uid_t uid; - bool linger; + int linger; char *name; struct dual_timestamp timestamp; char *state; diff --git a/src/shared/bus-util.c b/src/shared/bus-util.c index 8e3307d..5241099 100644 --- a/src/shared/bus-util.c +++ b/src/shared/bus-util.c @@ -1048,7 +1048,7 @@ static int map_basic(sd_bus *bus, const char *member, sd_bus_message *m, sd_bus_ case SD_BUS_TYPE_BOOLEAN: { unsigned b; - bool *p = userdata; + int *p = userdata; r = sd_bus_message_read_basic(m, type, &b); if (r < 0) diff --git a/src/timedate/timedatectl.c b/src/timedate/timedatectl.c index 7f61cf0..553ef67 100644 --- a/src/timedate/timedatectl.c +++ b/src/timedate/timedatectl.c @@ -57,11 +57,11 @@ typedef struct StatusInfo { char *timezone; usec_t rtc_time; - bool rtc_local; + int rtc_local; - bool ntp_enabled; - bool ntp_capable; - bool ntp_synced; + int ntp_enabled; + int ntp_capable; + int ntp_synced; } StatusInfo; static void status_info_clear(StatusInfo *info) { -- 2.7.4
