From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Szymon Janc To: linux-bluetooth@vger.kernel.org Cc: Szymon Janc Subject: [PATCH v2] shared: Fix not calling destroy callback while clearing up handlers Date: Thu, 9 Jan 2014 17:56:13 +0100 Message-Id: <1389286573-8986-1-git-send-email-szymon.janc@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Szymon Janc read/write_watch_destroy is be called after io_set_read/write_handler exits. This was resulting in io destroy callback being NULLem before destroy was called resulting in io destroy not being called at all. Fix this by assigning destroy callback only if setting non-NULL callback. destroy_watch will clean it when called. Fix following valgrind report: 168 (120 direct, 48 indirect) bytes in 1 blocks are definitely lost in loss record 34 of 36 at 0x4C2C494: calloc (in /usr/lib/valgrind/ vgpreload_memcheck-amd64-linux.so) by 0x409BAE: mgmt_new (mgmt.c:372) by 0x409D05: mgmt_new_default (mgmt.c:469) by 0x40E100: test_pre_setup (android-tester.c:371) by 0x40AD84: start_tester (tester.c:586) by 0x4E7C3B5: g_main_context_dispatch (in /lib/x86_64-linux-gnu/ libglib-2.0.so.0.3800.1) by 0x4E7C707: ???
