2009-10-06Port -net dump to QemuOptsMark McLoughlin
Note, not incrementing nb_host_devs in net_init_dump() is intentional. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Port -net vde to QemuOptsMark McLoughlin
The net_vde_init() change is needed because we now pass NULL pointers instead of empty strings for group/sock if they're not set. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-06Port -net tap to QemuOptsMark McLoughlin
Some parameters are not valid with fd=. Rather than having a separate parameter description table for validating fd=, it's easir to just check for those invalid parameters later. Note, the need to possible lookup a file descriptor name from the monitor is the reason why all these init functions are passed a Monitor pointer.

2009-10-06Port -net user to QemuOptsMark McLoughlin
The handling of guestfwd and hostfwd requires the previous changes to allow multiple values for each parameter. The only way to access those multiple values is to use qemu_opt_foreach(). Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Port -net none and -net nic to QemuOptsMark McLoughlin
We use a table of network types to look up the initialization function and parameter descriptions in net_client_init(). For now, we use QemuOpts for the 'none' and 'nic' types. Subsequent patches port the other types too and the special casing is removed. We're not parsing the full -net option string here as the type has been stripped from the string, so we do not use qemu_opts_parse() 'firstname' facility. This will also be rectified in subsequent patches. No functional changes are introduced by this patch. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Add qemu_net_optsMark McLoughlin
The first step in porting -net to QemuOpts. We do not include parameter descriptions in the QemuOptsList because we use the first parameter to choose which descriptions validate against. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Never overwrite a QemuOptMark McLoughlin
Rather than overwriting a QemuOpt, just add a new one to the tail and always do a reverse search for parameters to preserve the same behaviour. We use this order so that foreach() iterates over the opts in their original order. This will allow us handle options where multiple values for the same parameter is allowed - e.g. -net user,hostfwd= Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Add qemu_opts_validate() for post parsing validationMark McLoughlin
Several qemu command line options have a parameter whose value affects what other parameters are accepted for the option. In these cases, we can have an empty description table in the QemuOptsList and once the option has been parsed we can use a suitable description table to validate the other parameters based on the value of that parameter.

2009-10-06Make qemu_opts_parse() handle empty stringsMark McLoughlin
Rather than making callers explicitly handle empty strings by using qemu_opts_create(), we can easily have qemu_opts_parse() handle empty parameter strings. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Remove double error message for -device option parsingMark McLoughlin
qemu_opts_parse() gives a suitable error message in all failure cases so we can remove the error message from the caller. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Remove double error message in qemu_option_set()Mark McLoughlin
qemu_opt_set() prints an error message in all failure cases, so qemu_set_option() doesn't need to print another error. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Remove bogus error message from qemu_opts_set()Mark McLoughlin
The only way qemu_opts_create() can fail is if a QemuOpts with that id already exists and fail_if_exists=1. In that case, we already print an error which makes more sense than the one in qemu_opts_set(). Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-06Drop config_error(), use qemu_error() insteadMarkus Armbruster
Diagnostic output goes to stderr, except when we're in a monitor command, when it goes to the monitor instead. config_error() implements this with a monitor argument: if it's non-null, report there, else to stderr. This obliges us to pass the monitor down various call chains, to make it available to config_error(). The recently created qemu_error() doesn't need a monitor argument to route output. Use it. There's one user-visible difference: config_error() prepended "qemu: " to a message bound for stderr. qemu_error() doesn't, which means the prefix goes away with this commit. If such a prefix is desired for stderr, then I figure it should be slapped on all error messages, not just the ones that used to go through config_error().

2009-10-06Don't exit() in config_error()Markus Armbruster
Propagating errors up the call chain is tedious. In startup code, we can take a shortcut: terminate the program. This is wrong elsewhere, the monitor in particular. config_error() tries to cater for both customers: it terminates the program unless its mon parameter tells it it's working for the monitor. Its users need to return status anyway (unless passing a null mon argument, which none do), which their users need to check. So this automatic exit buys us exactly nothing useful. Only the dangerous delusion that we can get away without returning status. Some of its users fell for that. Their callers continue executing after failure when working for the monitor. This bites monitor command host_net_add in two places: * net_slirp_init() continues after slirp_hostfwd(), slirp_guestfwd(), or slirp_smb() failed, and may end up reporting success. This happens for "host_net_add user guestfwd=foo": it complains about the invalid guest forwarding rule, then happily creates the user network without guest forwarding. * net_client_init() can't detect slirp_guestfwd() failure, and gets fooled by net_slirp_init() lying about success. Suppresses its "Could not initialize device" message. Add the missing error reporting, make sure errors are checked, and drop the exit() from config_error().

2009-10-06Make net_client_init() consume slirp_configs even on errorMarkus Armbruster
net_slirp_init() walks slirp_configs, and stops when it encounters one that doesn't work. Instead of consuming slirp_configs members there, consume them in the sole caller. This makes sure all are consumed. Before, the tail starting with the non-working one was left in place, where it made the next net_slirp_init() fail again.

2009-10-06Reorganize option rom (+linux kernel) loading.Gerd Hoffmann
This patch adds infrastructure to maintain memory regions which must be restored on reset. That includes roms (vga bios and option roms on pc), but is also used when loading linux kernels directly. Features: - loading files is supported. - passing blobs is supported. - target address range is supported (for optionrom area). - fixed target memory address is supported (linux kernel). New in v2: - writes to ROM are done only at initial boot. - also handle aout and uimage loaders. - drop unused fread_targphys() function. The final memory layout is created once all memory regions are registered. The option roms get addresses assigned and the registered regions are checked against overlaps. Finally all data is copyed to the guest memory. Advantages: (1) Filling memory on initial boot and on reset takes the same code path, making reset more robust. (2) The need to keep track of the option rom load address is gone. (3) Due to (2) option roms can be loaded outside pc_init(). This allows to move the pxe rom loading into the nic drivers for example. Additional bonus: There is a 'info roms' monitor command now. The patch also switches over pc.c and removes the option_rom_setup_reset() and load_option_rom() functions.

2009-10-05Fix pci_add nic not to exit on bad modelMarkus Armbruster
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to create the NIC. When MODEL is unknown or "?", this prints to stderr and terminates the program. Change pci_nic_init() not to treat "?" specially, and to return NULL on failure. Switch uses during startup to new convenience wrapper pci_nic_init_nofail(), which behaves just like pci_nic_init() used to do. Bonus bug fix: we now check for qdev_init() failing there.

2009-10-05Make it obvious that pci_nic_init() can't failMarkus Armbruster
Before this patch, pci_nic_init() returns NULL when it can't find the model in pci_nic_models[]. Except this can't happen, because qemu_check_nic_model_list() just searched for model in pci_nic_models[], and terminated the program on failure. Repeating the search here is pointless. Instead, change qemu_check_nic_model_list() to return the model's array index. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-05Fix pci_add storage not to exit on bad first argumentMarkus Armbruster
Monitor command "pci_add ADDR storage ..." does its work in qemu_pci_hot_add_nic(). It called pci_create(..., ADDR) to create the device. That's wrong, because pci_create() terminates the program when ADDR is invalid. Use pci_get_bus_devfn() and pci_create_noinit() instead.

2009-10-05Fix pci_vga_init() not to ignore bus argumentMarkus Armbruster
Commit a414c306 converted all VGA devices to qdev. It used pci_create_simple() for all devices, except for this one it used pci_create(). That's wrong, because it uses PCI bus#0 regardless of the bus argument. Fix by switching to pci_create_noinit().

2009-10-05vnc: Set invalid buffer pointers to NULLStefan Weil

2009-10-05eepro100: Don't allow guests to fail assertionsKevin Wolf
The idea of using assert() for input validation is rather questionable. Let's remove it from eepro100, so that guests need to find more interesting ways if they want to crash qemu. This patch replaces asserts that are directly dependent on guest-accessible data by other means of error handling.

2009-10-05qcow2: Increase maximum cluster size to 2 MBKevin Wolf
This patch increases the maximum qcow2 cluster size to 2 MB. Starting with 128k clusters, L2 tables span 2 GB or more of virtual disk space, causing 32 bit truncation and wraparound of signed integers. Therefore some variables need to use a larger data type. While being at reviewing data types, change some integers that are used for array indices to unsigned. In some places they were checked against some upper limit but not for negative values. This could avoid potential segfaults with corrupted qcow2 images. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
