2019-07-19configure: only link capstone to emulation targetsDaniel P. Berrangé
Only the emulators link to code that uses capstone, so adding it to the global LIBs places undesirable dependancies on other binaries, in particular the tools. There is no variable that covers both user emulation and machine emulation, so add a new "$libs_cpu" for this purpose. In particular this removes the 8 MB capstone dep from the things qemu-img links against, allowing for a more minimal installation in scenarios that don't want system emulators installed.

2019-07-19crypto: fix function signatures for nettle 2.7 vs 3Daniel P. Berrangé
Nettle version 2.7.x used 'unsigned int' instead of 'size_t' for length parameters in functions. Use a local typedef so that we can build with the correct signature depending on nettle version, as we already do in the cipher code.

2019-07-19linux-user: fix to handle variably sized SIOCGSTAMP with new kernelsDaniel P. Berrangé
The SIOCGSTAMP symbol was previously defined in the asm-generic/sockios.h header file. QEMU sees that header indirectly via sys/socket.h In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115 the asm-generic/sockios.h header no longer defines SIOCGSTAMP. Instead it provides only SIOCGSTAMP_OLD, which only uses a 32-bit time_t on 32-bit architectures. The linux/sockios.h header then defines SIOCGSTAMP using either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even on 32-bit architectures To cope with this we must now convert the old and new type from the target to the host one.

Structure ucontext for MIPS is defined in the following way in Linux kernel: (arch/mips/include/uapi/asm/ucontext.h, lines 54-64) struct ucontext { /* Historic fields matching asm-generic */ unsigned long uc_flags; struct ucontext *uc_link; stack_t uc_stack; struct sigcontext uc_mcontext; sigset_t uc_sigmask; /* Extended context structures may follow ucontext */ unsigned long long uc_extcontext[0]; }; Fix the structure target_ucontext for MIPS to reflect the definition above, except the correction for field uc_extcontext, which will follow at some later time.

Recently we found a behavior change after commit 6ade45f2ac93611 ('char-pty: Print "char device redirected" message to stdout'). When we redirect output to a file, the message "char device redirected to PTY_NAME (label LABEL)" would not be seen at the beginning of the file. Instead, the message is displayed after QEMU quit. This will block test automation. The reason is this message is printed after we set line buffer mode. So move this to the beginning.

Until recently, target install used to recurse into target directories in its recipe: it ran make install in a for-loop.

Commit 1338a4b "Makefile: Reuse all's recursion machinery for clean and install" moved the target recursion to dependencies. That's good (the commit message explains why), but I forgot to add dependencies to ensure make runs the sub-make install only after completing target all. Do that now.

2019-07-15iotests: Compare error messages in 030Max Reitz
Currently, 030 just compares the error class, which does not say anything. Before HEAD^ added throttling to test_overlapping_4, that test actually usually failed because node2 was already gone, not because it was the commit and stream job were not allowed to overlap. Prevent such problems in the future by comparing the error description instead.

2019-07-15iotests: Fix throttling in 030Max Reitz
Currently, TestParallelOps in 030 creates images that are too small for job throttling to be effective. This is reflected by the fact that it never undoes the throttling. Increase the image size and undo the throttling when the job should be completed. Also, add throttling in test_overlapping_4, or the jobs may not be so overlapping after all. In fact, the error usually emitted here is that node2 simply does not exist, not that overlapping jobs are not allowed -- the fact that this job ignores the exact error messages and just checks the error class is something that should be fixed in a follow-up patch.

2019-07-15block: Deep-clear inherits_fromMax Reitz
BDS.inherits_from does not always point to an immediate parent node. When launching a block job with a filter node, for example, the node directly below the filter will not point to the filter, but keep its old pointee (above the filter). If that pointee goes away while the job is still running, the node's inherits_from will not be updated and thus point to garbage. To fix this, bdrv_unref_child() has to check not only the parent node's immediate children for nodes whose inherits_from needs to be cleared, but its whole subtree.

2019-07-15nvme: Set number of queues later in nvme_init()Michal Privoznik
When creating the admin queue in nvme_init() the variable that holds the number of queues created is modified before actual queue creation. This is a problem because if creating the queue fails then the variable is left in inconsistent state. This was actually observed when I tried to hotplug a nvme disk. The control got to nvme_file_open() which called nvme_init() which failed and thus nvme_close() was called which in turn called nvme_free_queue_pair() with queue being NULL. This lead to an instant crash: #0 0x000055d9507ec211 in nvme_free_queue_pair (bs=0x55d952ddb880, q=0x0) at block/nvme.c:164 #1 0x000055d9507ee180 in nvme_close (bs=0x55d952ddb880) at block/nvme.c:729 #2 0x000055d9507ee3d5 in nvme_file_open (bs=0x55d952ddb880, options=0x55d952bb1410, flags=147456, errp=0x7ffd8e19e200) at block/nvme.c:781 #3 0x000055d9507629f3 in bdrv_open_driver (bs=0x55d952ddb880, drv=0x55d95109c1e0 <bdrv_nvme>, node_name=0x0, options=0x55d952bb1410, open_flags=147456, errp=0x7ffd8e19e310) at block.c:1291 #4 0x000055d9507633d6 in bdrv_open_common (bs=0x55d952ddb880, file=0x0, options=0x55d952bb1410, errp=0x7ffd8e19e310) at block.c:1551 #5 0x000055d950766881 in bdrv_open_inherit (filename=0x0, reference=0x0, options=0x55d952bb1410, flags=32768, parent=0x55d9538ce420, child_role=0x55d950eaade0 <child_file>, errp=0x7ffd8e19e510) at block.c:3063 #6 0x000055d950765ae4 in bdrv_open_child_bs (filename=0x0, options=0x55d9541cdff0, bdref_key=0x55d950af33aa "file", parent=0x55d9538ce420, child_role=0x55d950eaade0 <child_file>, allow_none=true, errp=0x7ffd8e19e510) at block.c:2712 #7 0x000055d950766633 in bdrv_open_inherit (filename=0x0, reference=0x0, options=0x55d9541cdff0, flags=0, parent=0x0, child_role=0x0, errp=0x7ffd8e19e908) at block.c:3011 #8 0x000055d950766dba in bdrv_open (filename=0x0, reference=0x0, options=0x55d953d00390, flags=0, errp=0x7ffd8e19e908) at block.c:3156 #9 0x000055d9507cb635 in blk_new_open (filename=0x0, reference=0x0, options=0x55d953d00390, flags=0, errp=0x7ffd8e19e908) at block/block-backend.c:389 #10 0x000055d950465ec5 in blockdev_init (file=0x0, bs_opts=0x55d953d00390, errp=0x7ffd8e19e908) at blockdev.c:602 Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Message-id: 927aae40b617ba7d4b6c7ffe74e6d7a2595f8e86.1562770546.git.mprivozn@redhat.com Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Maxim Levitsky <mlevitsk@redhat.com> Signed-off-by: Max Reitz <mreitz@redhat.com>

2019-07-15migration: allow private destination ram with x-ignore-sharedPeng Tao
By removing the share ram check, qemu is able to migrate to private destination ram when x-ignore-shared capability is on. Then we can create multiple destination VMs based on the same source VM. This changes the x-ignore-shared migration capability to work similar to Lai's original bypass-shared-memory work(https://lists.gnu.org/archive/html/qemu-devel/2018-04/msg00003.html) which enables kata containers (https://katacontainers.io) to implement the VM templating feature. An example usage in kata containers(https://katacontainers.io): 1. Start the source VM: qemu-system-x86 -m 2G \ -object memory-backend-file,id=mem0,size=2G,share=on,mem-path=/tmpfs/template-memory \ -numa node,memdev=mem0 2. Stop the template VM, set migration x-ignore-shared capability, migrate "exec:cat>/tmpfs/state", quit it 3. Start target VM: qemu-system-x86 -m 2G \ -object memory-backend-file,id=mem0,size=2G,share=off,mem-path=/tmpfs/template-memory \ -numa node,memdev=mem0 \ -incoming defer 4. connect to target VM qmp, set migration x-ignore-shared capability, migrate_incoming "exec:cat /tmpfs/state" 5. create more target VMs repeating 3 and 4 Cc: Dr. David Alan Gilbert <dgilbert@redhat.com> Cc: Yury Kotov <yury-kotov@yandex-team.ru> Cc: Jiangshan Lai <laijs@hyper.sh> Cc: Xu Wang <xu@hyper.sh> Signed-off-by: Peng Tao <tao.peng@linux.alibaba.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Message-Id: <1560494113-1141-1-git-send-email-tao.peng@linux.alibaba.com> Signed-off-by: Juan Quintela <quintela@redhat.com>
