2010-07-01QDict: Introduce new iteration APILuiz Capitulino
It's composed of functions qdict_first() and qdict_next(), plus functions to access QDictEntry values. This API was suggested by Markus Armbruster <armbru@redhat.com> and it offers full control over the iteration process. The usage is simple, the following example prints all keys in 'qdict' (it's hopefully better than any English description): QDict *qdict; const QDictEntry *ent; [...] for (ent = qdict_first(qdict); ent; ent = qdict_next(qdict, ent)) { printf("%s ", qdict_entry_key(ent)); } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-07-01QDict: Introduce functions to retrieve QDictEntry valuesLuiz Capitulino
Next commit will introduce a new QDict iteration API which returns QDictEntry entries, but we don't want users to directly access its members since QDictEntry should be private to QDict. In the near future this kind of data type will be turned into a forward reference. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-07-01QDict: Small terminology changeLuiz Capitulino
Let's call a 'hash' only what is returned by our hash function, anything else is a 'bucket'. This helps avoiding confusion with regard to how we traverse our table. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2010-07-01QError: Enhance QERR_DEVICE_NOT_ACTIVE's user descLuiz Capitulino
The 'by the guest' part is misleading, it could be disabled by the host too. We will likely need more surgery if we care for the distinction, just dropping the problematic part is good enough for now. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2010-07-01QMP: Fix error reporting in the async APILuiz Capitulino
The current asynchronous command API doesn't return a QMP response when the async command fails. This is easy to reproduce with the balloon command (the sole async command we have so far): run qemu w/o the '-balloon virtio' option and try to issue the balloon command via QMP: no response will be sent to the client. This commit fixes the problem by making qmp_async_cmd_handler() return the handler's error code and then calling monitor_protocol_emitter() if the handler has returned an error.

2010-07-01net: delete QemuOpts when net_client_init() fails.Yoshiaki Tamura
This fixes the following scenario using QMP. First, put a bogus argument "foo" to "type", which results in an error. {"execute": "netdev_add", "arguments": { "type": "foo", "id": "netdev1" } } Then, call it again with correct argument "user". {"execute": "netdev_add", "arguments": { "type": "user", "id": "netdev1" } } This results in "DuplicatedId" error. Because the first command was invalid, it should be able to reuse the same "id", and the second command should work.

2010-06-30qdev-properties: Fix (u)intXX parsersKevin Wolf
scanf calls must not use PRI constants, they have probably the wrong size and corrupt memory. We could replace them by SCN ones, but strtol is simpler than scanf here anyway. While at it, also fix the parsers to reject garbage after the number ("4096xyz" was accepted before).

2010-06-30net: Fix VM start with '-net none'Amit Shah
Commit 50e32ea8f31035877decc10f1075aa0e619e09cb changed the behaviour for the return type of net_client_init() when a nic type with no init method was specified. 'none' is one such nic type. Instead of returning 0, which gets interpreted as an index into the nd_table[] array, we switched to returning -1, which signifies an error as well. That broke VM start with '-net none'. Testing was only done with the monitor command 'pci_add', which doesn't fail. The correct fix would still be to return 0+ values from net_client_init() only when the return value can be used as an index to refer to an entry in nd_table[]. With the current code, callers can erroneously poke into nd_table[0] when -net nic is used, which can lead to badness. However, this commit just returns to the previous behaviour before the offending commit. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-06-30x86: svm: Always clear event_inj on vmexitJan Kiszka

2010-06-29lsi53c895a: fix Phase Mismatch JumpPaolo Bonzini
lsi_bad_phase has a bug in the choice of pmjad1/pmjad2. This does not matter with Linux guests because it uses just one routine for both, but it breaks Windows 64-bit guests. This is the text from the spec: "[The PMJCTL] bit controls which decision mechanism is used when jumping on phase mismatch. When this bit is cleared the LSI53C895A will use Phase Mismatch Jump Address 1 (PMJAD1) when the WSR bit is cleared and Phase Mismatch Jump Address 2 (PMJAD2) when the WSR bit is set. When this bit is set the LSI53C895A will use jump address one (PMJAD1) on data out (data out, command, message out) transfers and jump address two (PMJAD2) on data in (data in, status, message in) transfers." Which means: CCNTL0.PMJCTL 0 SCNTL2.WSR = 0 PMJAD1 0 SCNTL2.WSR = 1 PMJAD2 1 out PMJAD1 1 in PMJAD2 In qemu, what you get instead is: CCNTL0.PMJCTL 0 out PMJAD1 0 in PMJAD2 <<<<< 1 out PMJAD1 1 in PMJAD1 <<<<< Considering that qemu always has SCNTL2.WSR cleared, the two marked cases (corresponding to phase mismatch on input) are always jumping to the wrong PMJAD register. The patch implements the correct semantics. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
