From 7cf6b6092697b682c7ef46e97a6b0db5e68cf57b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Fabian=20Gr=C3=BCnbichler?= Date: Wed, 17 Nov 2021 10:41:17 +0100 Subject: [PATCH] fix #3728: handle machine without type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit libguestfs starts their helper VMs with `-machine accel=..` without a machine type, and our pve version suffix handling would segfault in that case. there might be other scripted use cases that are affected as well. this regression was introduced with the rebase of our patch set on top of 6.1.0 Fixes: f376b2b9e2fc1f0c8f9c6275e96ede5f423c4126 Signed-off-by: Fabian Grünbichler --- ...E-Allow-version-code-in-machine-type.patch | 22 ++++++++++--------- 1 file changed, 12 insertions(+), 10 deletions(-) diff --git a/debian/patches/pve/0024-PVE-Allow-version-code-in-machine-type.patch b/debian/patches/pve/0024-PVE-Allow-version-code-in-machine-type.patch index c54a5f8..0eb9682 100644 --- a/debian/patches/pve/0024-PVE-Allow-version-code-in-machine-type.patch +++ b/debian/patches/pve/0024-PVE-Allow-version-code-in-machine-type.patch @@ -93,7 +93,7 @@ index d87cf6e103..e5010236f3 100644 g_slist_free(machines); if (local_err) { error_append_hint(&local_err, "Use -machine help to list supported machines\n"); -@@ -3312,12 +3318,29 @@ void qemu_init(int argc, char **argv, char **envp) +@@ -3312,12 +3318,31 @@ void qemu_init(int argc, char **argv, char **envp) case QEMU_OPTION_machine: { bool help; @@ -109,15 +109,17 @@ index d87cf6e103..e5010236f3 100644 + + // PVE version is specified with '+' as seperator, e.g. pc-i440fx+pvever + name = qdict_get_try_str(machine_opts_dict, "type"); -+ name_len = strlen(name); -+ pvever_index = strcspn(name, "+"); -+ if (pvever_index < name_len) { -+ name_clean = g_strndup(name, pvever_index); -+ pvever = g_strndup(name + pvever_index + 1, name_len - pvever_index - 1); -+ qdict_put_str(machine_opts_dict, "pvever", pvever); -+ qdict_put_str(machine_opts_dict, "type", name_clean); -+ g_free(name_clean); -+ g_free(pvever); ++ if (name != NULL) { ++ name_len = strlen(name); ++ pvever_index = strcspn(name, "+"); ++ if (pvever_index < name_len) { ++ name_clean = g_strndup(name, pvever_index); ++ pvever = g_strndup(name + pvever_index + 1, name_len - pvever_index - 1); ++ qdict_put_str(machine_opts_dict, "pvever", pvever); ++ qdict_put_str(machine_opts_dict, "type", name_clean); ++ g_free(name_clean); ++ g_free(pvever); ++ } + } + break;
