From f38857914ab5c9cc55aac05795e1886963a5fd04 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 18 Aug 2014 17:44:17 +0200 Subject: bus-util: simplify bus_verify_polkit_async() a bit First, let's drop the "bus" argument, we can determine it from the message anyway. Secondly, determine the right callback/userdata pair automatically from what is currently is being dispatched. This should simplify things a lot for us, since it makes it unnecessary to pass pointers through the original handlers through all functions when we process messages, which might require authentication. --- src/login/logind-dbus.c | 64 ++++++++++++++++++++++--------------------------- 1 file changed, 29 insertions(+), 35 deletions(-) (limited to 'src/login') diff --git a/src/login/logind-dbus.c b/src/login/logind-dbus.c index bcfcba2d07..acef5119b1 100644 --- a/src/login/logind-dbus.c +++ b/src/login/logind-dbus.c @@ -1029,14 +1029,13 @@ static int method_set_user_linger(sd_bus *bus, sd_bus_message *message, void *us if (!pw) return errno ? -errno : -ENOENT; - r = bus_verify_polkit_async(bus, - &m->polkit_registry, - message, - CAP_SYS_ADMIN, - "org.freedesktop.login1.set-user-linger", - interactive, - error, - method_set_user_linger, m); + r = bus_verify_polkit_async( + message, + CAP_SYS_ADMIN, + "org.freedesktop.login1.set-user-linger", + interactive, + &m->polkit_registry, + error); if (r < 0) return r; if (r == 0) @@ -1202,14 +1201,13 @@ static int method_attach_device(sd_bus *bus, sd_bus_message *message, void *user if (!seat_name_is_valid(seat)) return sd_bus_error_setf(error, SD_BUS_ERROR_INVALID_ARGS, "Seat %s is not valid", seat); - r = bus_verify_polkit_async(bus, - &m->polkit_registry, - message, - CAP_SYS_ADMIN, - "org.freedesktop.login1.attach-device", - interactive, - error, - method_attach_device, m); + r = bus_verify_polkit_async( + message, + CAP_SYS_ADMIN, + "org.freedesktop.login1.attach-device", + interactive, + &m->polkit_registry, + error); if (r < 0) return r; if (r == 0) @@ -1234,14 +1232,13 @@ static int method_flush_devices(sd_bus *bus, sd_bus_message *message, void *user if (r < 0) return r; - r = bus_verify_polkit_async(bus, - &m->polkit_registry, - message, - CAP_SYS_ADMIN, - "org.freedesktop.login1.flush-devices", - interactive, - error, - method_flush_devices, m); + r = bus_verify_polkit_async( + message, + CAP_SYS_ADMIN, + "org.freedesktop.login1.flush-devices", + interactive, + &m->polkit_registry, + error); if (r < 0) return r; if (r == 0) @@ -1535,8 +1532,7 @@ static int method_do_shutdown_or_sleep( blocked = manager_is_inhibited(m, w, INHIBIT_BLOCK, NULL, false, true, uid, NULL); if (multiple_sessions) { - r = bus_verify_polkit_async(m->bus, &m->polkit_registry, message, CAP_SYS_BOOT, - action_multiple_sessions, interactive, error, method, m); + r = bus_verify_polkit_async(message, CAP_SYS_BOOT, action_multiple_sessions, interactive, &m->polkit_registry, error); if (r < 0) return r; if (r == 0) @@ -1544,8 +1540,7 @@ static int method_do_shutdown_or_sleep( } if (blocked) { - r = bus_verify_polkit_async(m->bus, &m->polkit_registry, message, CAP_SYS_BOOT, - action_ignore_inhibit, interactive, error, method, m); + r = bus_verify_polkit_async(message, CAP_SYS_BOOT, action_ignore_inhibit, interactive, &m->polkit_registry, error); if (r < 0) return r; if (r == 0) @@ -1553,8 +1548,7 @@ static int method_do_shutdown_or_sleep( } if (!multiple_sessions && !blocked) { - r = bus_verify_polkit_async(m->bus, &m->polkit_registry, message, CAP_SYS_BOOT, - action, interactive, error, method, m); + r = bus_verify_polkit_async(message, CAP_SYS_BOOT, action, interactive, &m->polkit_registry, error); if (r < 0) return r; if (r == 0) @@ -1691,7 +1685,7 @@ static int method_can_shutdown_or_sleep( blocked = manager_is_inhibited(m, w, INHIBIT_BLOCK, NULL, false, true, uid, NULL); if (multiple_sessions) { - r = bus_verify_polkit(m->bus, message, CAP_SYS_BOOT, action_multiple_sessions, false, &challenge, error); + r = bus_verify_polkit(message, CAP_SYS_BOOT, action_multiple_sessions, false, &challenge, error); if (r < 0) return r; @@ -1704,7 +1698,7 @@ static int method_can_shutdown_or_sleep( } if (blocked) { - r = bus_verify_polkit(m->bus, message, CAP_SYS_BOOT, action_ignore_inhibit, false, &challenge, error); + r = bus_verify_polkit(message, CAP_SYS_BOOT, action_ignore_inhibit, false, &challenge, error); if (r < 0) return r; @@ -1720,7 +1714,7 @@ static int method_can_shutdown_or_sleep( /* If neither inhibit nor multiple sessions * apply then just check the normal policy */ - r = bus_verify_polkit(m->bus, message, CAP_SYS_BOOT, action, false, &challenge, error); + r = bus_verify_polkit(message, CAP_SYS_BOOT, action, false, &challenge, error); if (r < 0) return r; @@ -1840,7 +1834,7 @@ static int method_inhibit(sd_bus *bus, sd_bus_message *message, void *userdata, if (m->action_what & w) return sd_bus_error_setf(error, BUS_ERROR_OPERATION_IN_PROGRESS, "The operation inhibition has been requested for is already running"); - r = bus_verify_polkit_async(bus, &m->polkit_registry, message, CAP_SYS_BOOT, + r = bus_verify_polkit_async(message, CAP_SYS_BOOT, w == INHIBIT_SHUTDOWN ?
