From 606303a93ea52a70ebba55bb3152820e630f2164 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Mon, 2 Mar 2015 11:36:35 +0100 Subject: sd-bus: sync kdbus.h (ABI break) After some reconsideration, we decided to move the binary protocol back to 64-bit wide UIDs and GIDs. After all, it should be possible to redefine [gu]id_t to uint64_t and things should continue to work. As we want to avoid such data types in kdbus.h, let's move back to 64-bit values and be safe. In sd-bus, we have to do a translation between uint64_t and gid_t now for supplementary gids. Some inline comments have also been updated in kdbus upstream. --- src/libsystemd/sd-bus/kdbus.h | 29 +++++++++++++++++------------ 1 file changed, 17 insertions(+), 12 deletions(-) (limited to 'src/libsystemd/sd-bus/kdbus.h') diff --git a/src/libsystemd/sd-bus/kdbus.h b/src/libsystemd/sd-bus/kdbus.h index 6cbd01c503..fc1d77dd7c 100644 --- a/src/libsystemd/sd-bus/kdbus.h +++ b/src/libsystemd/sd-bus/kdbus.h @@ -70,14 +70,14 @@ struct kdbus_notify_name_change { * KDBUS_ITEM_CREDS */ struct kdbus_creds { - __u32 uid; - __u32 euid; - __u32 suid; - __u32 fsuid; - __u32 gid; - __u32 egid; - __u32 sgid; - __u32 fsgid; + __u64 uid; + __u64 euid; + __u64 suid; + __u64 fsuid; + __u64 gid; + __u64 egid; + __u64 sgid; + __u64 fsgid; } __attribute__((__aligned__(8))); /** @@ -463,8 +463,10 @@ struct kdbus_item { * cookie identifies the message and the * respective reply carries the cookie * in cookie_reply - * @KDBUS_MSG_NO_AUTO_START: Do not start a service, if the addressed - * name is not currently active + * @KDBUS_MSG_NO_AUTO_START: Do not start a service if the addressed + * name is not currently active.
