HFP: Fix connection colision handling * When there is a connection collison, and remote device is trying to connect to HFP server channel while we try to connect to remote's server channel as a client. If the remote device succssfully connect to us, we should drop our connection request to remote device and accept remote device's connection request. As result, we will observe 1. Our connection request fails, this propagate up to Java layer and also clean up any states in these layers 2. Remote connection request succeeds, this propagate up to Java layer as well as a new incoming connection * Added BTA_AG_COLLISION_EVT to formally handle AG collision in state machine * Modified bta_ag_resume_open to re-send BTA_AG_API_OPEN_EVT instead of modifying the state machine state directly. State machine states should only be modified by state machine handler * Ignore RFCOMM open event if PORT_CheckConnection fails * Added StackRfcommTest.TestConnectionCollision to reproduce this scenario with 100% certainty * Add static checks to HFP BTA state machine to make sure action and event indices match enum sizes Bug: 77224743 Test: connect to multiple remote devices with HFP, MAP and PBAP StackRfcommTest.TestConnectionCollision btestplans/details/158641/3975 Change-Id: Ib3652784b123abe195e7bd30421ef5f4345b1d4d Merged-In: Ib3652784b123abe195e7bd30421ef5f4345b1d4d (cherry picked from commit 88cc85a086bf90e1e669fd689276c6e658286af2)
Just build AOSP - Fluoride is there by default.
Instructions for Ubuntu, tested on 14.04 with Clang 3.5.0 and 16.10 with Clang 3.8.0
mkdir ~/fluoride cd ~/fluoride git clone https://android.googlesource.com/platform/system/bt
Install dependencies (require sudo access):
cd ~/fluoride/bt build/install_deps.sh
Then fetch third party dependencies:
cd ~/fluoride/bt mkdir third_party cd third_party git clone https://github.com/google/googletest.git git clone https://android.googlesource.com/platform/external/aac git clone https://android.googlesource.com/platform/external/libchrome git clone https://android.googlesource.com/platform/external/libldac git clone https://android.googlesource.com/platform/external/modp_b64 git clone https://android.googlesource.com/platform/external/tinyxml2
And third party dependencies of third party dependencies:
cd fluoride/bt/third_party/libchrome/base/third_party mkdir valgrind cd valgrind curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h
NOTE: If system/bt is checked out under AOSP, then create symbolic links instead of downloading sources
cd system/bt mkdir third_party cd third_party ln -s ../../../external/aac aac ln -s ../../../external/libchrome libchrome ln -s ../../../external/libldac libldac ln -s ../../../external/modp_b64 modp_b64 ln -s ../../../external/tinyxml2 tinyxml2 ln -s ../../../external/googletest googletest
cd ~/fluoride/bt gn gen out/Default
cd ~/fluoride/bt ninja -C out/Default all
This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace "all" with the target of your choice, e.g. ninja -C out/Default net_test_osi
.
cd ~/fluoride/bt/out/Default LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride
Follows the Chromium project Eclipse Setup Instructions until "Optional: Building inside Eclipse" section (don't do that section, we will set it up differently)
Generate Eclipse settings:
cd system/bt gn gen --ide=eclipse out/Default
In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML location under system/bt/out/Default
Right click on the project. Go to Preferences->C/C++ Build->Builder Settings. Uncheck "Use default build command", but instead using "ninja -C out/Default"
Goto Behaviour tab, change clean command to "-t clean"
