2014-10-03util: Emancipate id_wellformed() from QemuOptsMarkus Armbruster3-16/+30
IDs have long spread beyond QemuOpts: not everything with an ID necessarily goes through QemuOpts. Commit 9aebf3b is about such a case: block layer names are meant to be well-formed IDs, but some of them don't go through QemuOpts, and thus weren't checked. The commit fixed that the straightforward way: rename the internal QemuOpts helper id_wellformed() to qemu_opts_id_wellformed() and give it external linkage. Instead of using it directly in block.c, the commit adds wrapper bdrv_is_valid_name(), probably to hide the connection to QemuOpts. Go one logical step further: emancipate IDs from QemuOpts. Rename the function back to id_wellformed(), and put it in another file. While there, clean up its value to bool. Peel off the bdrv_is_valid_name() wrapper. [Replaced stray return 0 with return false to match bool returns used elsewhere in id_wellformed(). --Stefan] Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-09-25block: Validate node-nameKevin Wolf1-2/+2
The device_name of a BlockDriverState is currently checked because it is always used as a QemuOpts ID and qemu_opts_create() checks whether such IDs are wellformed. node-name is supposed to share the same namespace, but it isn't checked currently. This patch adds explicit checks both for device_name and node-name so that the same rules will still apply even if QemuOpts won't be used any more at some point. qemu-img used to use names with spaces in them, which isn't allowed any more. Replace them with underscores. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com>
2014-09-16util/qemu-sockets.c: Support specifying IPv4 or IPv6 in socket_dgram()Peter Maydell1-2/+1
Currently you can specify whether you want a UDP chardev backend to be IPv4 or IPv6 using the ipv4 or ipv6 options if you use the QemuOpts parsing code in inet_dgram_opts(). However the QMP struct parsing code in socket_dgram() doesn't provide this flexibility (which in turn prevents us from converting the UDP backend handling to the new style QAPI framework). Use the existing inet_addr_to_opts() function to convert the remote->inet address to option strings; this handles ipv4 and ipv6 flags as well as host and port. (It will also convert any 'to' specification, which is harmless as it is ignored in this context.)

In this file, we don't check the return value of malloc/strdup/realloc which may fail. Instead of using these routines, we use the GLib memory APIs g_malloc/g_strdup/g_realloc. They will exit on allocation failure, so there is no need to test for failure, which would be fine for setup.

2014-07-18module: Don't complain when a module is absentAndreas Färber1-3/+0
The current implementation depends on a configure-time generated list of block modules. When any of them is absent, module_load() emits a warning. This is suboptimal because extracting code to modules was mainly done to allow separate packaging of modules with intrusive dependencies. Absence of optional packages then leads to absence of modules and an error message, which users may recognize as new and report as error.

Well, if it gets called twice or more. On the first call, when @dst is NULL some initialization is done during which @dst->head list gets initialized. The list is initialized in a way, so that the list tail points at the list head. However, the next time qemu_opts_append() is called for new options to be added, g_realloc() may move @dst to a new address making the old list tail point at an invalid address. If that's the case, we must update the list pointers. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2014-06-16QemuOpts: cleanup tmp 'allocated' member from QemuOptsListChunyan Liu1-24/+3
Now only qemu_opts_append uses 'allocated' to indicate free memory. For this function only, we can also let result list's (const char *) members point to input list's members, only if the input list has longer lifetime than result list. In current code, that is true. So, we can remove the 'allocated' member from QemuOptsList definition to keep code clean. Signed-off-by: Chunyan Liu <cyliu@suse.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

Export qemu_opt_find for qcow2 driver using it. After replacing QEMUOptionParameter with QemuOpts, qcow2 driver will use qemu_opt_find to judge if an option is explicitly set, to replace the usage of .assigned in QEMUOptionParameter.

2014-06-16QemuOpts: add qemu_opt_get_*_del functions for replace workChunyan Liu1-13/+104
Add qemu_opt_get_del, qemu_opt_get_bool_del, qemu_opt_get_number_del and qemu_opt_get_size_del to replace the same handling of QEMUOptionParameter (get and delete). Several drivers are coded to parse a known subset of options, then remove them from the list before handing all remaining options to a second driver for further option processing. get_*_del makes it easier to retrieve a known option (or its default) and remove it from the list all in one action. Share common helper function: For qemu_opt_get_bool/size/number, they and their get_*_del counterpart could share most of the code except whether or not deleting the opt from option list, so generate common helper functions. For qemu_opt_get and qemu_opt_get_del, keep code duplication, since 1. qemu_opt_get_del returns malloc'd memory while qemu_opt_get returns in-place memory 2. qemu_opt_get_del returns (char *), qemu_opt_get returns (const char *), and could not change to (char *), since in one case, it will return desc->def_value_str, which is (const char *).

2014-06-16QemuOpts: change opt->name|str from (const char *) to (char *)Chunyan Liu1-2/+2
qemu_opt_del() already assumes that all QemuOpt instances contain malloc'd name and value; but it had to cast away const because opts_start_struct() was doing its own thing and using static storage instead. By using the correct type and malloced strings everywhere, the usage of this struct becomes clearer.
