2018-07-10block: Use uint64_t for BdrvTrackedRequest byte fieldsFam Zheng1-2/+2
This matches the types used for bytes in the rest parts of block layer. In the case of bdrv_co_truncate, new_bytes can be the image size which probably doesn't fit in a 32 bit int. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2018-07-10block: Use BdrvChild to discardFam Zheng1-2/+2
Other I/O functions are already using a BdrvChild pointer in the API, so make discard do the same. It makes it possible to initiate the same permission checks before doing I/O, and much easier to share the helper functions for this, which will be added and used by write, truncate and copy range paths.

2018-07-10block: add BDRV_REQ_SERIALISING flagVladimir Sementsov-Ogievskiy1-1/+13
Serialized writes should be used in copy-on-write of backup(sync=none) for image fleecing scheme. We need to change an assert in bdrv_aligned_pwritev, added in 28de2dcd88de. The assert may fail now, because call to wait_serialising_requests here may become first call to it for this request with serializing flag set. It occurs if the request is aligned (otherwise, we should already set serializing flag before calling bdrv_aligned_pwritev and correspondingly waited for all intersecting requests). However, for aligned requests, we should not care about outdating of previously read data, as there no such data. Therefore, let's just update an assert to not care about aligned requests.

2018-07-10block/io: fix copy_rangeVladimir Sementsov-Ogievskiy1-0/+12
Here two things are fixed: 1. Architecture On each recursion step, we go to the child of src or dst, only for one of them. So, it's wrong to create tracked requests for both on each step. It leads to tracked requests duplication. 2. Wait for serializing requests on write path independently of BDRV_REQ_NO_SERIALISING Before commit 9ded4a01149 "backup: Use copy offloading", BDRV_REQ_NO_SERIALISING was used for only one case: read in copy-on-write operation during backup. Also, the flag was handled only on read path (in bdrv_co_preadv and bdrv_aligned_preadv). After 9ded4a01149, flag is used for not waiting serializing operations on backup target (in same case of copy-on-write operation). This behavior change is unsubstantiated and potentially dangerous, let's drop it and add additional asserts and documentation.

2018-07-10block: Poll after drain on attaching a nodeKevin Wolf2-0/+11
Commit dcf94a23b1 ('block: Don't poll in parent drain callbacks') removed polling in bdrv_child_cb_drained_begin() on the grounds that the original bdrv_drain() already will poll and BdrvChildRole.drained_begin calls must not cause graph changes (and therefore must not call aio_poll() or the recursion through the graph will break. This reasoning is correct for calls through bdrv_do_drained_begin(). However, BdrvChildRole.drained_begin is also called when a node that is already in a drained section (i.e. bdrv_do_drained_begin() has already returned and therefore can't poll any more) is attached to a new parent. In this case, we must explicitly poll to have all requests completed before the drained new child can be attached to the parent. In bdrv_replace_child_noperm(), we know that we're not inside the recursion of bdrv_do_drained_begin() because graph changes are not allowed there, and bdrv_replace_child_noperm() is a graph change. The call of BdrvChildRole.drained_begin() must therefore be followed by a BDRV_POLL_WHILE() that waits for the completion of requests.

2018-07-09boards.h: Remove doc comment reference to nonexistent functionPeter Maydell1-2/+1
commit b08199c6fbea1 accidentally added a reference to a doc comment to a nonexistent memory_region_allocate_aux_memory(). This was a leftover from a previous version of the patchset which defined memory_region_allocate_aux_memory() for "allocate RAM MemoryRegion and register it for migration" and left "memory_region_init_ram()" with its original semantics of "allocate RAM MR but do not register for migration". In the end we decided on the approach of "memory_region_init_ram() registers the MR for migration, and memory_region_init_ram_nomigrate() is a new function which does not", but this comment change got left in by mistake.

handle_qmp_command() reports certain errors right away. This is wrong when OOB is enabled, because the errors can "jump the queue" then, as the previous commit demonstrates. To fix, we need to delay errors until dispatch. Do that for semantic errors, mostly by reverting ill-advised parts of commit cf869d53172 "qmp: support out-of-band (oob) execution". Bonus: doesn't run qmp_dispatch_check_obj() twice, once in handle_qmp_command(), and again in do_qmp_dispatch(). That's also due to commit cf869d53172.

Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS connections than using certificates. It requires only a simple secret key: $ mkdir -m 0700 /tmp/keys $ psktool -u rjones -p /tmp/keys/keys.psk $ cat /tmp/keys/keys.psk rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc The key can be secretly shared between clients and servers. Clients must specify the directory containing the "keys.psk" file and a username (defaults to "qemu"). Servers must specify only the directory. Example NBD client: $ qemu-img info \ --object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \ --image-opts \ file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/ Example NBD server using qemu-nbd: $ qemu-nbd -t -x / \ --object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \ --tls-creds tls0 \ image.qcow2 Example NBD server using nbdkit: $ nbdkit -n -e / -fv \ --tls=on --tls-psk=/tmp/keys/keys.psk \ file file=disk.img Signed-off-by: Richard W.M.

2018-07-03vga: disable global_vmstate for 3.0+ machine typesGerd Hoffmann1-0/+16
Move global_vmstate from vga_common_init() parameter to VGACommonState field. Set global_vmstate to true for isa vga devices, so nothing changes here. virtio-vga and secondary-vga already set global_vmstate to false so no change here either. All other pci vga devices get a new global-vmstate property, defaulting to false. A compat property flips it to true for older machine types. With this in place you don't get a vmstate section naming conflict any more when adding multiple pci vga devices to your vm.

2018-07-03ppc4xx_i2c: Rewrite to model hardware more closelyBALATON Zoltan1-1/+2
Rewrite to make it closer to how real device works so that guest OS drivers can access I2C devices. Previously this was only a hack to allow U-Boot to get past accessing SPD EEPROMs but to support other I2C devices and allow guests to access them we need to model real device more properly.

2018-07-02nbd/client: Add x-dirty-bitmap to query bitmap from serverEric Blake1-0/+1
In order to test that the NBD server is properly advertising dirty bitmaps, we need a bare minimum client that can request and read the context. Since feature freeze for 3.0 is imminent, this is the smallest workable patch, which replaces the qemu block status report with the results of the NBD server's dirty bitmap (making it very easy to use 'qemu-img map --output=json' to learn where the dirty portions are). Note that the NBD protocol defines a dirty section with the same bit but opposite sense that normal "base:allocation" uses to report an allocated section; so in qemu-img map output, "data":true corresponds to clean, "data":false corresponds to dirty. A more complete solution that allows dirty bitmaps to be queried at the same time as normal block status will be required before this addition can lose the x- prefix. Until then, the fact that this replaces normal status with dirty status means actions like 'qemu-img convert' will likely misbehave due to treating dirty regions of the file as if they are unallocated. The next patch adds an iotest to exercise this new code. Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20180702191458.28741-2-eblake@redhat.com>

2018-07-02tcg: Define and use new tlb_hit() and tlb_hit_page() functionsPeter Maydell2-2/+24
The condition to check whether an address has hit against a particular TLB entry is not completely trivial. We do this in various places, and in fact in one place (get_page_addr_code()) we have got the condition wrong. Abstract it out into new tlb_hit() and tlb_hit_page() inline functions (one for a known-page-aligned address and one for an arbitrary address), and use them in all the places where we had the condition correct. This is a no-behaviour-change patch; we leave fixing the buggy code in get_page_addr_code() to a subsequent patch.

2018-07-02tcg: simplify !CONFIG_TCG handling of tb_invalidate_*Paolo Bonzini1-5/+3
There is no need for a stub, since tb_invalidate_phys_addr can be excised altogether when TCG is disabled. This is a bit cleaner since it avoids using code that is clearly specific to user-mode emulation (it calls mmap_lock/unlock) for the !CONFIG_TCG case.
