Date: Mon, 13 May 2013 10:07:11 +0800 From: Chen Gang <gang.chen@...anux.com> To: Jiri Kosina <jkosina@...e.cz> CC: Gustavo Padovan <gustavo@...ovan.org>, David Herrmann <dh.herrmann@...il.com>, Marcel Holtmann <marcel@...tmann.org>, Johan Hedberg <johan.hedberg@...il.com>, David Miller <davem@...emloft.net>, andrei.emeltchenko@...el.com, "linux-bluetooth@...r.kernel.org" <linux-bluetooth@...r.kernel.org>, netdev <netdev@...r.kernel.org> Subject: [PATCH v3] Bluetooth: hidp: using strlcpy instead of strncpy, also beautify code. For NUL terminated string, need always let it ended by zero. Since have already called memcpy() to initialize 'ci', so need not redundant initialization. Better use ''if(session->hid) {} else if(session->input) {}"" instead of ''if(session->hid) {}; if(session->input) {};'' Signed-off-by: Chen Gang <gang.chen@...anux.com> --- net/bluetooth/hidp/core.c | 14 ++++---------- 1 files changed, 4 insertions(+), 10 deletions(-) diff --git a/net/bluetooth/hidp/core.c b/net/bluetooth/hidp/core.c index 940f5ac..f13a8da 100644 --- a/net/bluetooth/hidp/core.c +++ b/net/bluetooth/hidp/core.c @@ -76,25 +76,19 @@ static void hidp_copy_session(struct hidp_session *session, struct hidp_conninfo ci->flags = session->flags; ci->state = BT_CONNECTED; - ci->vendor = 0x0000; - ci->product = 0x0000; - ci->version = 0x0000; - if (session->input) { ci->vendor = session->input->id.vendor; ci->product = session->input->id.product; ci->version = session->input->id.version; if (session->input->name) - strncpy(ci->name, session->input->name, 128); + strlcpy(ci->name, session->input->name, 128); else - strncpy(ci->name, "HID Boot Device", 128); - } - - if (session->hid) { + strlcpy(ci->name, "HID Boot Device", 128); + } else if (session->hid) { ci->vendor = session->hid->vendor; ci->product = session->hid->product; ci->version = session->hid->version; - strncpy(ci->name, session->hid->name, 128); + strlcpy(ci->name, session->hid->name, 128); } } -- 1.7.7.6 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
