From a3a55a2edb7c0fd72bc62a8a4c719a1e1983e6ac Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Fri, 4 Dec 2009 15:24:09 -0200 Subject: monitor: Introduce 'block_passwd' command When using encrypted disk images, QEMU will prompt the user for passwords when started. This makes sense for the user protocol, but doesn't for QMP. The solution is to have Monitor command which allows the user or a Client to set passwords in advance, so that we avoid the prompt completely. This is what block_passwd does, for example: (QEMU) block_passwd ide0-hd0 foobar Signed-off-by: Luiz Capitulino Signed-off-by: Anthony Liguori --- monitor.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'monitor.c') diff --git a/monitor.c b/monitor.c index ba76f3416d..27c696b2d4 100644 --- a/monitor.c +++ b/monitor.c @@ -772,6 +772,22 @@ static void do_eject(Monitor *mon, const QDict *qdict, QObject **ret_data) eject_device(mon, bs, force); } +static void do_block_set_passwd(Monitor *mon, const QDict *qdict, + QObject **ret_data) +{ + BlockDriverState *bs; + + bs = bdrv_find(qdict_get_str(qdict, "device")); + if (!bs) { + qemu_error_new(QERR_DEVICE_NOT_FOUND, qdict_get_str(qdict, "device")); + return; + } + + if (bdrv_set_key(bs, qdict_get_str(qdict, "password")) < 0) { + qemu_error_new(QERR_INVALID_PASSWORD); + } +} + static void do_change_block(Monitor *mon, const char *device, const char *filename, const char *fmt) { -- cgit v1.2.1
