From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Jakub Tyszkowski To: linux-bluetooth@vger.kernel.org Cc: Jakub Tyszkowski Subject: [PATCHv4 06/13] android/tester: Add generic hook to handle pdu exchange Date: Thu, 2 Oct 2014 10:10:54 +0200 Message-Id: <1412237461-20373-7-git-send-email-jakub.tyszkowski@tieto.com> In-Reply-To: <1412237461-20373-1-git-send-email-jakub.tyszkowski@tieto.com> References: <1412237461-20373-1-git-send-email-jakub.tyszkowski@tieto.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This allows tester-main to register hooks for certain CID to automatically perform pdu exchange by registering array of pdu pairs (request_pdu, response_pdu). When end_pdu is used instead of request_pdu, response is sent immediately without incoming pdu verification. A pair with end_pdus set as request and response is considered as the end of pdu pairs array. This callback can also handle sdp request<->response while transaction ID for the response is swaped to match the one from SDP request. 'emu_l2cap_cid_data' is used to pass tha appropriate data to the hook mechanism. It is similar to 'emu_cid_data" used in other testers and eventually will replace those. --- android/tester-main.c | 61 +++++++++++++++++++++++++++++++++++++++++++++++++++ android/tester-main.h | 10 +++++++++ 2 files changed, 71 insertions(+) diff --git a/android/tester-main.c b/android/tester-main.c index 5bf9096..5ef0401 100644 --- a/android/tester-main.c +++ b/android/tester-main.c @@ -16,6 +16,7 @@ */ #include +#include "src/shared/util.h" #include "emulator/bthost.h" #include "tester-main.h" @@ -2127,6 +2128,66 @@ void emu_add_l2cap_server_action(void) schedule_action_verification(step); } +static void print_data(const char *str, void *user_data) +{ + tester_debug("tester: %s", str); +} + +static void emu_generic_cid_hook_cb(const void *data, uint16_t len, + void *user_data) +{ + struct test_data *t_data = tester_get_data(); + struct emu_l2cap_cid_data *cid_data = user_data; + const struct pdu_set *pdus = cid_data->pdu; + struct bthost *bthost = hciemu_client_get_host(t_data->hciemu); + int i; + + for (i = 0; pdus[i].rsp.iov_base; i++) { + if (pdus[i].req.iov_base) { + if (pdus[i].req.iov_len != len) + continue; + + if (memcmp(pdus[i].req.iov_base, data, len)) + continue; + } + + if (pdus[i].rsp.iov_base) { + util_hexdump('>', pdus[i].rsp.iov_base, + pdus[i].rsp.iov_len, print_data, NULL); + + /* if its sdp pdu use transaction ID from request */ + if (cid_data->is_sdp) { + struct iovec rsp[3]; + + rsp[0].iov_base = pdus[i].rsp.iov_base; + rsp[0].iov_len = 1; + + rsp[1].iov_base = ((uint8_t *) data) + 1; + rsp[1].iov_len = 2; + + rsp[2].iov_base = pdus[i].rsp.iov_base + 3; + rsp[2].iov_len = pdus[i].rsp.iov_len - 3; + + bthost_send_cid_v(bthost, cid_data->handle, + cid_data->cid, rsp, 3); + } else { + bthost_send_cid_v(bthost, cid_data->handle, + cid_data->cid, &pdus[i].rsp, 1); + } + + } + } +} + +void tester_handle_l2cap_data_exchange(struct emu_l2cap_cid_data *cid_data) +{ + struct test_data *t_data = tester_get_data(); + struct bthost *bthost = hciemu_client_get_host(t_data->hciemu); + + bthost_add_cid_hook(bthost, cid_data->handle, cid_data->cid, + emu_generic_cid_hook_cb, cid_data); +} + static void rfcomm_connect_cb(uint16_t handle, uint16_t cid, void *user_data, bool status) { diff --git a/android/tester-main.h b/android/tester-main.h index 3ebad2b..aa56cd2 100644 --- a/android/tester-main.h +++ b/android/tester-main.h @@ -439,6 +439,14 @@ struct emu_set_l2cap_data { void *user_data; }; +struct emu_l2cap_cid_data { + const struct pdu_set *pdu; + + uint16_t handle; + uint16_t cid; + bool is_sdp; +}; + /* * Callback data structure should be enhanced with data * returned by callbacks.
