Re-structures MGMT handling such that it is used to detect kernel support of the mesh MGMT opcodes and events before selecting between using MGMT or the legacy raw HCI socket method. 2. Re-structures main() to allow command line to prefer MGMT over HCI or visa versa, plus optionally pass an explicte controller. 3. Adds mesh-io-mgmt as a transport. --- Makefile.mesh | 9 +- mesh/main.c | 39 +- mesh/mesh-io-api.h | 11 +- mesh/mesh-io-generic.c | 47 +-- mesh/mesh-io-mgmt.c | 788 +++++++++++++++++++++++++++++++++++++++++ mesh/mesh-io-mgmt.h | 11 + mesh/mesh-io-unit.c | 13 +- mesh/mesh-io.c | 189 +++++++--- mesh/mesh-io.h | 4 +- mesh/mesh-mgmt.c | 164 +++++++-- mesh/mesh-mgmt.h | 12 +- mesh/mesh.c | 6 +- mesh/mesh.h | 2 +- 13 files changed, 1154 insertions(+), 141 deletions(-) create mode 100644 mesh/mesh-io-mgmt.c create mode 100644 mesh/mesh-io-mgmt.h diff --git a/Makefile.mesh b/Makefile.mesh index fc28b0557..3047f362b 100644 --- a/Makefile.mesh +++ b/Makefile.mesh @@ -13,12 +13,11 @@ endif mesh_sources = mesh/mesh.h mesh/mesh.c \ mesh/net-keys.h mesh/net-keys.c \ mesh/mesh-io.h mesh/mesh-io.c \ - mesh/mesh-mgmt.c mesh/mesh-mgmt.h \ + mesh/mesh-mgmt.h mesh/mesh-mgmt.c \ mesh/error.h mesh/mesh-io-api.h \ - mesh/mesh-io-generic.h \ - mesh/mesh-io-generic.c \ - mesh/mesh-io-unit.h \ - mesh/mesh-io-unit.c \ + mesh/mesh-io-unit.h mesh/mesh-io-unit.c \ + mesh/mesh-io-mgmt.h mesh/mesh-io-mgmt.c \ + mesh/mesh-io-generic.h mesh/mesh-io-generic.c \ mesh/net.h mesh/net.c \ mesh/crypto.h mesh/crypto.c \ mesh/friend.h mesh/friend.c \ diff --git a/mesh/main.c b/mesh/main.c index dd99c3085..619b17d88 100644 --- a/mesh/main.c +++ b/mesh/main.c @@ -123,6 +123,12 @@ static void disconnect_callback(void *user_data) l_main_quit();
