guestfsd calls many different tools. Keeping track of all of them is
error prone. This patch introduces a new helper macro to put the command
string into its own ELF section:
GUESTFSD_EXT_CMD(C_variable, command_name);
This syntax makes it still possible to grep for used command names.
The actual usage of the collected list could be like this:
objcopy -j .guestfsd_ext_cmds -O binary daemon/guestfsd /dev/stdout |
tr '\0' '\n' | sort -u
The resulting output will be used to tell mkinitrd which programs to
copy into the initrd.

split_lines already sets reply_with_*, so calling it again would lose
protocol synchronization.

Previously a lot of daemon code used three variables (a string list,
'int size' and 'int alloc') to track growable strings buffers. This
commit implements a simple struct containing the same variables, but
using size_t instead of int:
struct stringsbuf {
char **argv;
size_t size;
size_t alloc;
};
Use it like this:
DECLARE_STRINGSBUF (ret);
//...
if (add_string (&ret, str) == -1)
return NULL;
//...
if (end_stringsbuf (&ret) == -1)
return NULL;
return ret.argv;

This is just a code clean-up with no functional change.
|
| |
|
|
|
|
| |
Fix the existing test to work correctly in this case.
Other cleanups.

RHEL5 shoult not support '-p', '-i' and '-o export' options.
But we just split it according to the '-p' option.

A NEW API blkid.
It can print the device attributes.
Use it after list-devices, we can list ower devices and the attributes
of each device.
Use it like:
blkid <device>
It's should be a usefull function.

On recent Debian, /etc/blkid.tab is now a symlink to /dev/.blkid.tab.
Rather than chasing the cache file around (it may move to /run in future)
use the -c /dev/null option to stop blkid from reading the cache.

If the blkid command returns 2, that means the value was not found.
Note that this changes the output of the vfs-type API when the
filesystem has no type (eg when it is empty). Previously this would
return an error. Now it returns empty string "".
We did not document this either way. Making it return empty string is
consistent with vfs-label and vfs-uuid.
This change broke list-filesystems, since that code was assuming that
vfs-type could only return a filesystem type or an error.

Remove both possible cache locations.
|
| |
|
|
|
|
|
|
|
|
|

These APIs generalize the existing 'get-e2label' and 'get-e2uuid'
calls, to provide calls which should be able to get the label
and UUID for most filesystem types. These use 'blkid' to do the
work.
I have tested that the blkid commands themselves work on RHEL 5.
(Suggested by Yufang Zhang).

By killing the cache file, we make blkid work in situations such
as a just-created filesystem.
|
| |
|
|
| |
Note that there is no change to the semantics of the code.

Change the appliance so PATH includes common directories. Thus
we don't need to hard-code paths to binaries (eg. "/sbin/fdisk")
everywhere.

The RPC stubs already prefix the command name to error messages.
The daemon doesn't have to do this. As a (small) benefit this also
makes the daemon slightly smaller.
Code in the daemon such as:
if (argv[0] == NULL) {
reply_with_error ("passed an empty list");
return NULL;
}
now results in error messages like this:
><fs> command ""
libguestfs: error: command: passed an empty list
(whereas previously you would have seen ..command: command:..)
