* Fix verbose packet dumping functions.Richard Jones2009-09-172-3/+11
| | | | | | | | | | Add the configure parameter --enable-packet-dump so that this code can be enabled without editing the source. This code is normally commented out, because it is too verbose unless you happen to be debugging the underlying protocol. Because it is normally commented out, I found it had bit-rotted slightly. This commit also fixes the obvious problems.
* 'len' should be an unsigned 32 bit int.Richard Jones2009-09-171-1/+1
| | | | | This only happened to work by accident before because 'unsigned len' happens to be 32 bit on all platforms we support.
* Add echo_daemon commandMatthew Booth2009-09-142-0/+74
| | | | | echo_daemon is a simple echo which can be used to test connectivity between the client and daemon.
* Ignore some more m4 files.Richard Jones2009-09-091-0/+1

* daemon: diagnose socket write failureJim Meyering2009-08-204-9/+19
| | | | | | | | | * daemon/proto.c (send_chunk): Don't ignore socket-write error. * daemon/proto.c (send_file_end): Return "int", not void, so we can propagate send_chunk failure to caller. * daemon/daemon.h (send_file_end): Update prototype. * daemon/tar.c (do_tar_out, do_tgz_out): Update uses of send_file_end. * daemon/upload.c (do_download): Likewise.
* mke2fs: Use e4fsprogs programs if available.Richard W.M. Jones2009-08-191-3/+46
| | | | | | | On RHEL 5, mke2fs is ancient, and there is a non-standard "mke4fs" binary which acts like the more recent mke2fs on Fedora. Since there are several annoyances and actual bugs in the ancient RHEL 5 mke2fs, use mke4fs instead if it's available.
* New 'modprobe' command.Matthew Booth2009-08-182-0/+41
| | | | Allow kernel modules to be loaded into the appliance.

| | | | | | | | | | * daemon/m4/gnulib-cache.m4: Add two modules: manywarnings, warnings. * daemon/configure.ac: Implement --enable-gcc-warnings, and selectively disable a few warning options that are either not useful or that provoke too many warnings for now. Define and AC_SUBST WARN_CFLAGS and WERROR_CFLAGS. * daemon/Makefile.am (guestfsd_CFLAGS): Use $(WARN_CFLAGS) and $(WERROR_CFLAGS), rather than just -Wall.

* do_umount: don't use RESOLVE_DEVICE anymoreJim Meyering2009-08-131-13/+9
| | | | | * daemon/mount.c (do_umount): Don't use RESOLVE_DEVICE here, now that the caller always invokes REQUIRE_ROOT_OR_RESOLVE_DEVICE.
* generator.ml: finish adding Dev_or_Path supportJim Meyering2009-08-132-4/+0
| | | | | | | | | | * src/generator.ml: Update all rules to handle Dev_or_Path. (the above changes to generator.ml are mostly mechanical) Emit a use of REQUIRE_ROOT_OR_RESOLVE_DEVICE. * daemon/upload.c (do_download): Remove use of REQUIRE_ROOT_OR_RESOLVE_DEVICE, now that it's automatically done in calling code. * daemon/file.c (do_file): Likewise.
