From: "howardchung@xxxxxxxxxx" <howardchung@xxxxxxxxxx> When kernel find out that the incoming Just-Works pairing is initiated by a paired device, it is user space's responsibility to decide the next action. This patch includes the following: - add JustWorksRepairing policy as an option in main.conf - handle the confirmation request from kernel --- The Just-Works repairing policy could be one of the following: - never: default; reject the repairing immediately. - confirm: prompt a confirmation dialog to user. - always: always accept the repairing. Changes in v2: - let RequestAuthorization handle the situation - remove the changes in client/ src/agent.c | 16 ++++++++++++++++ src/hcid.h | 8 ++++++++ src/main.c | 27 +++++++++++++++++++++++++++ src/main.conf | 5 +++++ 4 files changed, 56 insertions(+) diff --git a/src/agent.c b/src/agent.c index e0ffcd22f..e013ec85f 100644 --- a/src/agent.c +++ b/src/agent.c @@ -773,12 +773,28 @@ int agent_request_authorization(struct agent *agent, struct btd_device *device, GDestroyNotify destroy) { struct agent_request *req; + DBusError dbus_err; int err; err = agent_has_request(agent, device, AGENT_REQUEST_AUTHORIZATION); if (err) return err; + /* Just-Works repairing policy */ + if (device_is_paired(device, BDADDR_BREDR) || + device_is_paired(device, BDADDR_LE_PUBLIC)) { + if (main_opts.jw_repairing == JW_REPAIRING_NEVER) { + dbus_error_init(&dbus_err); + dbus_set_error_const(&dbus_err, + ERROR_INTERFACE ".Rejected", NULL); + cb(agent, &dbus_err, user_data); + return 0; + } else if (main_opts.jw_repairing == JW_REPAIRING_ALWAYS) { + cb(agent, NULL, user_data); + return 0; + } + } + DBG("Calling Agent.RequestAuthorization: name=%s, path=%s", agent->owner, agent->path); diff --git a/src/hcid.h b/src/hcid.h index adea85ce2..bcd2b9fa1 100644 --- a/src/hcid.h +++ b/src/hcid.h @@ -35,6 +35,12 @@ typedef enum { BT_GATT_CACHE_NO, } bt_gatt_cache_t; +enum { + JW_REPAIRING_NEVER, + JW_REPAIRING_CONFIRM, + JW_REPAIRING_ALWAYS, +} jw_repairing_t; + struct main_opts { char *name; uint32_t class; @@ -58,6 +64,8 @@ struct main_opts { uint16_t gatt_mtu; uint8_t key_size; + + jw_repairing_t jw_repairing; }; extern struct main_opts main_opts; diff --git a/src/main.c b/src/main.c index 1a6ab36a3..d67f469f1 100644 --- a/src/main.c +++ b/src/main.c @@ -93,6 +93,7 @@ static const char *supported_options[] = { "MultiProfile", "FastConnectable", "Privacy", + "JustWorksRepairing", NULL }; @@ -193,6 +194,20 @@ static bt_gatt_cache_t parse_gatt_cache(const char *cache) } } +static jw_repairing_t parse_jw_repairing(const char *jw_repairing) +{ + if (!strcmp(jw_repairing, "never")) { + return JW_REPAIRING_NEVER; + } else if (!strcmp(jw_repairing, "confirm")) { + return JW_REPAIRING_CONFIRM; + } else if (!strcmp(jw_repairing, "always")) { + return JW_REPAIRING_ALWAYS; + } else { + return JW_REPAIRING_NEVER; + } +} + + static void check_options(GKeyFile *config, const char *group, const char **options) { @@ -331,6 +346,18 @@ static void parse_config(GKeyFile *config) g_free(str); } + str = g_key_file_get_string(config, "General", + "JustWorksRepairing", &err); + if (err) { + DBG("%s", err->message); + g_clear_error(&err); + main_opts.jw_repairing = JW_REPAIRING_NEVER; + } else { + DBG("just_works_repairing=%s", str); + main_opts.jw_repairing = parse_jw_repairing(str); + g_free(str); + } + str = g_key_file_get_string(config, "General", "Name", &err); if (err) { DBG("%s", err->message); diff --git a/src/main.conf b/src/main.conf index 40687a755..bb5ff5b15 100644 --- a/src/main.conf +++ b/src/main.conf @@ -72,6 +72,11 @@ # Defaults to "off" # Privacy = off +# Specify the policy to the JUST-WORKS repairing initiated by peer +# Possible values: "never", "confirm", "always" +# Defaults to "never" +#JustWorksRepairing = never + [GATT] # GATT attribute cache. # Possible values: -- 2.25.0.225.g125e21ebc7-goog
