2019-01-14block: remove 'x' prefix from experimental bitmap APIsJohn Snow4-36/+36
The 'x' prefix was added because I was uncertain of the direction we'd take for the libvirt API. With the general approach solidified, I feel comfortable committing to this API for 4.0.

2019-01-14blockdev: n-ary bitmap mergeJohn Snow2-35/+62
Especially outside of transactions, it is helpful to provide all-or-nothing semantics for bitmap merges. This facilitates the coalescing of multiple bitmaps into a single target for the "checkpoint" interpretation when assembling bitmaps that represent arbitrary points in time from component bitmaps. This is an incompatible change from the preliminary version of the API.

2019-01-14block/dirty-bitmap: remove assertion from restoreJohn Snow1-1/+0
When making a backup of a dirty bitmap (for transactions), we want to restore that backup whether or not the bitmap is enabled. It is perfectly valid to write into bitmaps that are disabled. It is only illegitimate for the guest to have done so. Remove this assertion.

2019-01-14blockdev: abort transactions in reverse orderJohn Snow1-7/+7
Presently, we abort transactions in the same order they were processed in. Bitmap commands, though, attempt to restore backup data structures on abort. That's not valid, they need to be aborted in reverse chronological order. Replace the QSIMPLEQ data structure with a QTAILQ one, so we can iterate in reverse for the abort phase of the transaction.

2019-01-11qemu/queue.h: reimplement QTAILQ without pointer-to-pointersPaolo Bonzini3-106/+92
QTAILQ is a doubly linked list, with a pointer-to-pointer to the last element from the head, and the previous element from each node. But if you squint enough, QTAILQ becomes a combination of a singly-linked forwards list, and another singly-linked list which goes backwards and is circular. This is the idea that lets QTAILQ implement reverse iteration: only, because the backwards list points inside the node, accessing the previous element needs to go two steps back and one forwards. What this patch does is implement it in these terms, without actually changing the in-memory layout at all. The coexistence of the two lists is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in both directions; the union is needed so that the forwards pointer can have the correct type, as a sort of poor man's template. While there are other ways to get the same layout without a union, this one has the advantage of simpler operation in the debugger, because the fields tqh_first and tqe_next still exist as before the patch. Those fields are also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them. The advantage of the new representation is that the two-back-one-forward dance done by backwards accesses can be done all while operating on QTailQLinks. No casting to the head struct is needed anymore because, even though the QTailQLink's forward pointer is a void *, we can use typeof to recover the correct type. This patch only changes the implementation, not the interface. The next patch will remove the head struct name from the backwards visit macros. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-01-11qemu/queue.h: typedef QTAILQ headsPaolo Bonzini5-11/+16
This will be needed when we change the QTAILQ head and elem structs to unions. However, it is also consistent with the usage elsewhere in QEMU for other list head structs (see for example FsMountList). Note that most QTAILQs only need their name in order to do backwards walks. Those do not break with the struct->union change, and anyway the change will also remove the need to name heads when doing backwards walks, so those are not touched here.

Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct.

2019-01-11test: replace gtester with a TAP driverPaolo Bonzini7-52/+543
gtester is deprecated by upstream glib (see for example the announcement at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does not support tests that call g_test_skip in some glib stable releases. glib suggests instead using Automake's TAP support, which gtest itself supports since version 2.38 (QEMU's minimum requirement is 2.40). We do not support Automake, but we can use Automake's code to beautify the TAP output. I chose to use the Perl copy rather than the shell/awk one, with some changes so that it can accept TAP through stdin, in order to reuse Perl's TAP parsing package. This also avoids duplicating the parser between tap-driver.pl and tap-merge.pl.

2019-01-11scsi: esp: Defer command completion until previous interrupts have been handledGuenter Roeck4-9/+31
The guest OS reads RSTAT, RSEQ, and RINTR, and expects those registers to reflect a consistent state. However, it is possible that the registers can change after RSTAT was read, but before RINTR is read, when esp_command_complete() is called. Guest OS qemu -------- ---- [handle interrupt] Read RSTAT esp_command_complete() RSTAT = STAT_ST esp_dma_done() RSTAT |= STAT_TC RSEQ = 0 RINTR = INTR_BS Read RSEQ Read RINTR RINTR = 0 RSTAT &= ~STAT_TC RSEQ = SEQ_CD The guest OS would then try to handle INTR_BS combined with an old value of RSTAT. This sometimes resulted in lost events, spurious interrupts, guest OS confusion, and stalled SCSI operations. A typical guest error log (observed with various versions of Linux) looks as follows. scsi host1: Spurious irq, sreg=13. ... scsi host1: Aborting command [84531f10:2a] scsi host1: Current command [f882eea8:35] scsi host1: Queued command [84531f10:2a] scsi host1: Active command [f882eea8:35] scsi host1: Dumping command log scsi host1: ent[15] CMD val[44] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[00] event[0c] scsi host1: ent[16] CMD val[01] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[17] CMD val[43] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[18] EVENT val[0d] sreg[92] seqreg[04] sreg2[00] ireg[18] ss[00] event[0c] ...

2019-01-11esp-pci: Fix status register write erase controlGuenter Roeck1-3/+3
Per AM53C974 datasheet, definition of "SCSI Bus and Control (SBAC)" register: Bit 24 'STATUS' Write Erase Control This bit controls the Write Erase feature on bits 3:1 and bit 6 of the DMA Status Register ((B)+54h). When this bit is programmed to '1', the state of bits 3:1 are preserved when read. Bits 3:1 are only cleared when a '1' is written to the corresponding bit location. For example, to clear bit 1, the value of '0000_0010b' should be written to the register. When the DMA Status Preserve bit is '0', bits 3:1 are cleared when read. The status register is currently defined to bit 12, not bit 24. Also, its implementation is reversed: The status is auto-cleared if the bit is set to 1, and must be cleared explicitly when the bit is set to 0. This results in spurious interrupts reported by the Linux kernel, and in some cases even results in stalled SCSI operations. Set SBAC_STATUS to bit 24 and reverse the logic to fix the problem.

2019-01-11block/iscsi: cancel libiscsi task when ABORT TASK TMF completesStefan Hajnoczi1-2/+14
The libiscsi iscsi_task_mgmt_async() API documentation says: abort_task will also cancel the scsi task. The callback for the scsi task will be invoked with SCSI_STATUS_CANCELLED The libiscsi implementation does not fulfil this promise. The task's callback is not invoked and its struct iscsi_pdu remains in the internal list (effectively leaked). This patch invokes the libiscsi iscsi_scsi_cancel_task() API to force the task's callback to be invoked with SCSI_STATUS_CANCELLED when the ABORT TASK TMF completes and the task's callback hasn't been invoked yet.

iscsi_aio_cancel() does not increment the request's reference count, causing a use-after-free when ABORT TASK finishes after the request has already completed. There are some additional issues with iscsi_aio_cancel(): 1. Several ABORT TASKs may be sent for the same task if iscsi_aio_cancel() is invoked multiple times. It's better to avoid this just in case the command identifier is reused. 2. The iscsilun->mutex protection is missing in iscsi_aio_cancel().

2019-01-11memory: update coalesced_range on transaction_commitPaolo Bonzini1-4/+16
The e1000 driver calls memory_region_add_coalescing but kvm_coalesce_mmio_region is never called for those regions. The bug dates back to the introduction of the memory region API; to fix it, delete and re-add coalesced MMIO ranges when building the FlatViews. Because coalesced MMIO regions apply to all address spaces, the has_coalesced_range flag has to be changed into an int.

When compiling with "--disable-tcg", we currently still use "tcg" as default accelerator. "kvm" should be used in this case instead. Also, some downstream distros provide QEMU binaries which have "kvm" in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use KVM by default - and some users might want to do something similar with upstream binaries, too.
