* 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.
* Implement 'debug ls' and 'debug ll' commands.Richard Jones2009-08-182-3/+64
| | | | These commands can be used to list files in the appliance.

* daemon: enable -Werror and many gcc warnings when --enable-gcc-warningsJim Meyering2009-08-173-2/+66
| | | | | | | | | | * 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.
* xattr.c: avoid warning about comparison between signed and unsignedJim Meyering2009-08-171-4/+6
| | | | * daemon/xattr.c (getxattrs): Use an unsigned index.

| | | | * daemon/daemon.h (main_loop): Use "noreturn" attribute.
* sfdisk.c, fallocate.c: use a string literal as formatJim Meyering2009-08-172-3/+3
| | | | | * daemon/fallocate.c (do_fallocate): Format was not a string literal. * daemon/sfdisk.c (sfdisk): Likewise.
* wc, blockdev: avoid warnings about discarding "const" qualifiersJim Meyering2009-08-172-2/+2
| | | | | * daemon/wc.c (wc): Make "flag" param const. * daemon/blockdev.c (call_blockdev): Likewise, for "switc".
* daemon/zero: don't ignore write and close errorsJim Meyering2009-08-171-4/+14
| | | | * daemon/zero.c (do_zero): Detect write and close errors.
* guestfsd.c: don't perform arithmetic on void pointersJim Meyering2009-08-171-2/+4
| | | | * daemon/guestfsd.c (xread, xwrite): Use char* pointers instead.
* command.c: avoid shadowing a global functionJim Meyering2009-08-171-4/+4
| | | | * daemon/command.c (do_sh_lines, do_sh): Do not shadow global "command".
* avoid warning about old-style no-param function definitionJim Meyering2009-08-172-3/+3
| | | | | * daemon/df.c (do_df, do_df_h): Add "void". * sync.c (do_sync): Likewise.
* adjust const "**" pointers to avoid warningsJim Meyering2009-08-178-35/+31

| | | | | | | | | | mkfs-b: Pass the -b (blocksize) parameter to mkfs. mke2journal and friends: Lets you create external ext2 journals on devices. mke2fs-J and friends: Lets you create ext2/3/4 filesystems with external journals.
* build: avoid "make sytnax-check" failureJim Meyering2009-08-141-1/+1
| | | | * daemon/configure.ac: Change a leading TAB to 8 spaces.
* appliance: Replace LANG=C with LC_ALL=CRichard Jones2009-08-131-1/+1

|
* selinux: Don't fail if libselinux is not found.Richard Jones2009-08-131-7/+3
|
* In rmmountpoint, have to explicitly check for ABS_PATH (*not* NEED_ROOT).Richard Jones2009-08-131-0/+3

|
* sfdisk: guard against buffer overflowJim Meyering2009-08-131-2/+15
| | | | | * daemon/sfdisk.c (sfdisk): Don't let outrageous "extra_flag" or "device" strings overflow a fixed-size buffer.
* 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.
* generator.ml: constify do_mkdtempJim Meyering2009-08-131-17/+8
| | | | | * daemon/dir.c (do_mkdtemp): Rewrite for a "const" parameter. * src/generator.ml (mkdtemp): Declare parameter to be of type Pathname.
* generator.ml: use new "Pathname" designationJim Meyering2009-08-1342-325/+175
| | | | | | | | | | Nearly every file-related function in daemons/*.c is affected: Remove this pair of statements from each affected do_* function: - NEED_ROOT (return -1); - ABS_PATH (dir, return -1); and change the type of the corresponding parameter to "const char *". * src/generator.ml: Emit NEED_ROOT just once, even when there are two or more Pathname args.
* fix daemon.h's use of NEED_ROOT-in-#defineJim Meyering2009-08-131-1/+1
|
* update all NEED_ROOT usesJim Meyering2009-08-1332-57/+57
| | | | | | run this command: git grep -l -w NEED_ROOT|xargs perl -pi -e \ 's/(NEED_ROOT) \((.*?)\)/$1 (return $2)/'
* * src/generator.ml: Change all `String "device"' to `Device "device"'.Jim Meyering2009-08-1313-53/+0
| | | | | | | | | | | | | | | | | | | | | Then update each affected function, removing each uses of RESOLVE_DEVICE, now that it's generated in caller from stub.c. * daemon/blockdev.c (call_blockdev): Remove use of RESOLVE_DEVICE. * daemon/devsparts.c (do_mkfs): Likewise. * daemon/ext2.c (do_e2fsck_f, do_get_e2label, do_get_e2uuid): Likewise.

* guestfsd.c: correct s/IS_DEVICE/RESOLVE_DEVICE/ in another commentJim Meyering2009-08-131-1/+1
|
* manually adjust ABS_PATH uses for new semanticsJim Meyering2009-08-131-1/+1
| | | | * daemon/file.c (do_cat): fix an ABS_PATH use
* update all uses of ABS_PATHJim Meyering2009-08-1329-55/+55
| | | | | | run this command: git grep -l -w ABS_PATH|xargs perl -pi -e \ 's/(?:ABS_PATH)( \(.*?,) (.*?)\)/ABS_PATH$1 return $2)/'
* propagate semantic changes to NEED_ROOT, NEED_ROOT_OR_IS_DEVICEJim Meyering2009-08-131-8/+8
| | | | | | changing IS_DEVICE semantics leads to changing semantics of NEED_ROOT_OR_IS_DEVICE and NEED_ROOT, too. * daemon/daemon.h: Update definitions.
* convert the last few, manuallyJim Meyering2009-08-132-2/+2
|
* change almost all uses: s/IS_DEVICE/RESOLVE_DEVICE/Jim Meyering2009-08-1315-32/+32
| | | | | | Use this command: git grep -l -w IS_DEVICE|xargs perl -pi -e \ 's/\b(?:IS_DEVICE)\b( \(.*?,) (.*?)\)/RESOLVE_DEVICE$1 return $2)/'
* * daemon/daemon.h (RESOLVE_DEVICE): Rename from IS_DEVICE.Jim Meyering2009-08-131-3/+3
| | | | | Change parameter from "errcode" (which would be returned) to "fail_stmt" so that a caller can specify e.g., "goto done" upon failure.
* Add 'setcon', 'getcon' commands to set and get the SELinux context.Richard Jones2009-08-133-0/+93
|
* Return error if allocations fail.Richard Jones2009-08-121-0/+12
|
* If using SELinux, mount /selinux in the appliance.Richard Jones2009-08-121-2/+8
| | | | | | If selinux=1 on the Linux kernel command line, then we mount /selinux in the appliance. We will also bind-mount this directory into guests when we run commands.
* daemon/ls: make do_ll require root, like all the restJim Meyering2009-08-111-7/+10
| | | | | * ls.c (do_ll): Do invoke "NEED_ROOT" here, and add a FIXME to provide a "debug ll" command with the semantics we're removing.
