2014-11-14ahci: unify sglist preparationJohn Snow1-2/+2
The intent of this patch is to further unify the creation and deletion of the sglist used for all AHCI transfers, including emulated PIO, ATAPI R/W, and native DMA R/W. By replacing ahci_start_transfer's call to ahci_populate_sglist with ahci_dma_prepare_buf, we reduce the number of direct calls where we manipulate the scatter-gather list in the AHCI code. To make this switch, the constant "0" passed as an offset in ahci_dma_prepare_buf is adjusted to use io_buffer_offset. For DMA pathways, this has no effect: io_buffer_offset is always updated to 0 at the beginning of a DMA transfer loop regardless. DMA pathways through ide_dma_cb() update the io_buffer_offset accordingly, and for circumstances where we might make several trips through this loop, this may actually correct a design flaw. For PIO pathways, the newly updated ahci_dma_prepare_buf will now prepare the sglist at the correct offset. It will also set io_buffer_size, but this is not used in the cmd_read_pio or cmd_write_pio pathways.

2014-11-14ide: repair PIO transfers for cases where nsector > 1John Snow2-1/+5
Currently, for emulated PIO transfers through the AHCI device, any attempt made to request more than a single sector's worth of data will result in the same sector being transferred over and over. For example, if we request 8 sectors via PIO READ SECTORS, the AHCI device will give us the same sector eight times. This patch adds offset tracking into the PIO pathways so that we can fulfill these requests appropriately.

2014-11-14ahci: Fix byte count regression for ATAPI/PIOJohn Snow1-0/+1
This patch fixes a regression caused by commit 659142ecf71a0da240ab0ff7cf929ee25c32b9bc. The problem occurs when we wish to return early from the ahci_start_transfer function, but are now updating the transferred byte count in the AHCI command header via ahci_commit_buf. This will cause problems in the Windows 8 installer. Don't update the byte count in the command header for the transmission of ATAPI packets: These commands will distort the final byte count of the actual data payload. The call to ahci_commit_buf remains in the "out" portion of the call in order to clean up the sglist. The byte count is maintained by forcing size to be 0.

2014-11-13QMP/input-send-event: make console parameter optionalAmos Kong3-10/+13
The 'QemuConsole' is the input source for handler, we share some input handlers to process the input events from different QemuConsole. Normally we only have one set of keyboard, mouse, usbtablet, etc. The devices have different mask, it's fine to just checking mask to insure that the handler has the ability to process the event. I saw we try to bind console to handler in usb/dev-hid.c, but display always isn't available at that time. If we have multiseat setup (as Gerd said), we only have 'problem' in this case. Actually event from different devices have the same effect for system, it's fine to always use the first available handler without caring about the console. For send-key command, we just pass a NULL for console parameter in calling qemu_input_event_send_key(NULL, ..), but 'input-send-event' needs to care more devices. Conclusion: Generally assigning the special console is meanless, and we can't directly remove the QMP parameter for compatibility. So we can make the parameter optional. The parameter might be useful for some special condition: we have multiple devices without binding console and they all have the ability(mask) to process events, and we don't want to use the first one.

2014-11-11linux-user: Fix up timer id handlingAlexander Graf2-21/+38
When creating a timer handle, we give the timer id a special magic offset of 0xcafe0000. However, we never mask that offset out of the timer id before we start using it to dereference our timer array. So we always end up aborting timer operations because the timer id is out of bounds. This was not an issue before my patch e52a99f756e ("linux-user: Simplify timerid checks on g_posix_timers range") because before we would blindly mask anything above the first 16 bits. This patch simplifies the code around timer id creation by introducing a proper target_timer_id typedef that is s32, just like Linux has it. It also changes the magic offset to a value that makes all timer ids be positive.

2014-11-11slirp/smbd: modify/set several parameters in generated smbd.confPeter Wu1-1/+8
The file sharing module should not handle printers, so disable it. The options 'load printers' and 'printing' have been available since the beginning (May 1996, commit 0e8fd3398771da2f016d72830179507f3edda51b). Option 'disable spoolss' is available since Samba 2.0.4, commit de5f42c9d9172592779fa2504d44544e3b6b1c0d). Next, "socket address" was reported as deprecated, use a combination of "interfaces" and "bind interfaces only" instead (available since October 1997, commit 79f4fb52c1ed56fd843f81b4eb0cdd2991d4d0f4). Override cache directory to avoid writing to a global directory. Option available since Samba 3.4.0, Jan 2009, commit 19a05bf2f485023b11b41dfae3f6459847d55ef7. Set "usershare max shared=0" to prevent a global directory from being used. Option available since Samba 3.0.23, February 2006, commit 5831715049f2d460ce42299963a5defdc160891b. The last option was introduced with Samba 3.4.0, but previously "state directory" was already added which exists in Samba 3.4.0. As unknown parameters are ignored (while printing a warning), it should be safe to add another option.

2014-11-10target-xtensa: add missing window check for entryMax Filippov2-0/+12
Entry opcode needs to check if moving to new register frame would cause register window overflow. Entry used in function prologue never overflows because preceding windowed call* opcode writes return address to the target register window frame, causing overflow exceptions at the point of call. But when a sequence of entry opcodes is used for register window spilling there may not be a call or other opcode that would cause window check between entries and they would not raise overflow exception themselves resulting in data corruption.
