2010-07-02blockdev: Clean up automatic drive deletionMarkus Armbruster7-7/+56
We automatically delete blockdev host parts on unplug of the guest device. Too much magic, but we can't change that now. The delete happens early in the guest device teardown, before the connection to the host part is severed. Thus, the guest part's pointer to the host part dangles for a brief time. No actual harm comes from this, but we'll catch such dangling pointers a few commits down the road. Clean up the dangling pointers by delaying the automatic deletion until the guest part's pointer is gone. Device usb-storage deliberately makes two qdev properties refer to the same drive, because it automatically creates a second device. Again, too much magic we can't change now. Multiple references worked okay before, but now free_drive() dies for the second one. Zap the extra reference.

2010-07-02Don't reset bs->is_temporary in bdrv_open_commonRyan Harper1-1/+0
To fix https://bugs.launchpad.net/qemu/+bug/597402 where qemu fails to call unlink() on temporary snapshots due to bs->is_temporary getting clobbered in bdrv_open_common() after being set in bdrv_open() which calls the former.

2010-07-02ide: Make it explicit that ide_create_drive() can't failMarkus Armbruster1-2/+1
All callers of ide_create_drive() ignore its value. Currently harmless, because it fails only when qdev_init() fails, which fails only when ide_drive_initfn() fails, which never fails. Brittle. Change it to die instead of silently ignoring failure. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-07-02block: allow filenames with colons again for host devicesChristoph Hellwig1-11/+18
Before the raw/file split we used to allow filenames with colons for host device only. While this was more by accident than by design people rely on it, so we need to bring it back.

2010-06-30net: Fix VM start with '-net none'Amit Shah1-1/+1
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>

2010-06-29lsi53c895a: fix Phase Mismatch JumpPaolo Bonzini1-3/+3
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>
