This patch defines the basics of a generic RPC protocol in XDR. This is wire ABI compatible with the original remote_protocol.x. It takes everything except for the RPC calls / events from that protocol - The basic header virNetMessageHeader (aka remote_message_header) - The error object virNetMessageError (aka remote_error) - Two dummy objects virNetMessageDomain & virNetMessageNetwork sadly needed to keep virNetMessageError ABI compatible with the old remote_error The RPC protocol supports method calls, async events and bidirectional data streams as before * src/Makefile.am: Add rules for generating RPC code from protocol & define a new libvirt-net-rpc.la helper library * src/rpc/virnetprotocol.x: New generic RPC protocol * src/rpc/virnetprotocol.c, src/rpc/virnetprotocol.h: Generated from virnetprotocol.x --- .x-sc_preprocessor_indentation | 1 + Makefile.am | 1 + src/Makefile.am | 34 ++++++- src/rpc/virnetprotocol.c | 206 ++++++++++++++++++++++++++++++++++++++ src/rpc/virnetprotocol.h | 136 +++++++++++++++++++++++++ src/rpc/virnetprotocol.x | 214 ++++++++++++++++++++++++++++++++++++++++ 6 files changed, 591 insertions(+), 1 deletions(-) create mode 100644 .x-sc_preprocessor_indentation create mode 100644 src/rpc/virnetprotocol.c create mode 100644 src/rpc/virnetprotocol.h create mode 100644 src/rpc/virnetprotocol.x diff --git a/.x-sc_preprocessor_indentation b/.x-sc_preprocessor_indentation new file mode 100644 index 0000000..30273f8 --- /dev/null +++ b/.x-sc_preprocessor_indentation @@ -0,0 +1 @@ +src/rpc/virnetprotocol.h \ No newline at end of file diff --git a/Makefile.am b/Makefile.am index c525e65..a400f59 100644 --- a/Makefile.am +++ b/Makefile.am @@ -21,6 +21,7 @@ syntax_check_exceptions = \ .x-sc_bindtextdomain \ .x-sc_m4_quote_check \ .x-sc_po_check \ + .x-sc_preprocessor_indentation \ .x-sc_prohibit_always_true_header_tests \ .x-sc_prohibit_asprintf \ .x-sc_prohibit_close \ diff --git a/src/Makefile.am b/src/Makefile.am index 196d8af..8837b43 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -531,6 +531,24 @@ else mv -f rp_qemu.c-t $(srcdir)/remote/qemu_protocol.c endif +rpcgen-net: + rm -f rp_net.c-t rp_net.h-t rp_net.c-t1 rp_net.c-t2 rp_net.h-t1 + $(RPCGEN) -h -o rp_net.h-t $(srcdir)/rpc/virnetprotocol.x + $(RPCGEN) -c -o rp_net.c-t $(srcdir)/rpc/virnetprotocol.x +if HAVE_GLIBC_RPCGEN + perl -w $(srcdir)/remote/rpcgen_fix.pl rp_net.h-t > rp_net.h-t1 + perl -w $(srcdir)/remote/rpcgen_fix.pl rp_net.c-t > rp_net.c-t1 + (echo '#include <config.h>';

Introduces a simple wrapper around the raw POSIX sockets APIs and name resolution APIs. Allows for easy creation of client and server sockets with correct usage of name resolution APIs for protocol agnostic socket setup. It can listen for UNIX and TCP stream sockets.

To facilitate creation of new clients using XDR RPC services, pull alot of the remote driver code into a set of reusable objects. - virNetClient: Encapsulates a socket connection to a remote RPC server. Handles all the network I/O for reading/writing RPC messages. Delegates RPC encoding and decoding to the registered programs - virNetClientProgram: Handles processing and dispatch of RPC messages for a single RPC (program,version). A program can register to receive async events from a client Each new client program now merely needs to define the list of RPC procedures & events it wants and their handlers. It does not need to deal with any of the network I/O functionality at all. --- po/POTFILES.in | 2 + src/Makefile.am | 13 +- src/rpc/virnetclient.c | 1090 +++++++++++++++++++++++++++++++++++++++++ src/rpc/virnetclient.h | 75 +++ src/rpc/virnetclientprogram.c | 301 ++++++++++++ src/rpc/virnetclientprogram.h | 82 +++ 6 files changed, 1562 insertions(+), 1 deletions(-) create mode 100644 src/rpc/virnetclient.c create mode 100644 src/rpc/virnetclient.h create mode 100644 src/rpc/virnetclientprogram.c create mode 100644 src/rpc/virnetclientprogram.h diff --git a/po/POTFILES.in b/po/POTFILES.in index bb84ea3..0595adf 100644 --- a/po/POTFILES.in +++ b/po/POTFILES.in @@ -58,6 +58,8 @@ src/qemu/qemu_monitor_json.c src/qemu/qemu_monitor_text.c src/qemu/qemu_security_dac.c src/remote/remote_driver.c +src/rpc/virnetclient.c +src/rpc/virnetclientprogram.c src/rpc/virnetmessage.c src/rpc/virnetsaslcontext.c src/rpc/virnetsocket.c diff --git a/src/Makefile.am b/src/Makefile.am index 15a70d6..9fbf210 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -1118,7 +1118,7 @@ libvirt_qemu_la_LIBADD = libvirt.la $(CYGWIN_EXTRA_LIBADD) EXTRA_DIST += $(LIBVIRT_QEMU_SYMBOL_FILE) -noinst_LTLIBRARIES += libvirt-net-rpc.la libvirt-net-rpc-server.la +noinst_LTLIBRARIES += libvirt-net-rpc.la libvirt-net-rpc-server.la libvirt-net-rpc-client.la libvirt_net_rpc_la_SOURCES = \ ../daemon/event.c \ @@ -1154,6 +1154,17 @@ libvirt_net_rpc_server_la_LDFLAGS = \ libvirt_net_rpc_server_la_LIBADD = \ $(CYGWIN_EXTRA_LIBADD) +libvirt_net_rpc_client_la_SOURCES = \ + rpc/virnetclientprogram.h rpc/virnetclientprogram.c \ + rpc/virnetclient.h rpc/virnetclient.c +libvirt_net_rpc_client_la_CFLAGS = \ + $(AM_CFLAGS) +libvirt_net_rpc_client_la_LDFLAGS = \ + $(AM_LDFLAGS) \ + $(CYGWIN_EXTRA_LDFLAGS) \ + $(MINGW_EXTRA_LDFLAGS)l +libvirt_net_rpc_client_la_LIBADD = \ + $(CYGWIN_EXTRA_LIBADD) libexec_PROGRAMS = diff --git a/src/rpc/virnetclient.c b/src/rpc/virnetclient.c new file mode 100644 index 0000000..27ee685 --- /dev/null +++ b/src/rpc/virnetclient.c @@ -0,0 +1,1090 @@ +/* + * virnetclient.c: generic network RPC client + * + * Copyright (C) 2006-2010 Red Hat, Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This guts the libvirtd daemon, removing all its networking and RPC handling code. Instead it calls out to the new virServerPtr APIs for all its RPC & networking work As a fallout all libvirtd daemon error reporting now takes place via the normal internal error reporting APIs. There is no need to call separate error reporting APIs in RPC code, nor should code use VIR_WARN/VIR_ERROR for reporting fatal problems anymore. NB, this mail has been edit to remove all the auto-generated code changes, to try & reduce the size somewhat.
