2018-03-26vhdx: Check for 4 GB maximum log size on creationKevin Wolf1-0/+4
It's unclear what the real maximum is, but we use an uint32_t to store the log size in vhdx_co_create(), so we should check that the given value fits in 32 bits. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Jeff Cody <jcody@redhat.com>

error_setg_errno() is meant for cases where we got an errno from the OS that can add useful extra information to an error message.

2018-03-26qcow2: Reset free_cluster_index when allocating a new refcount blockAlberto Garcia4-3/+40
When we try to allocate new clusters we first look for available ones starting from s->free_cluster_index and once we find them we increase their reference counts. Before we get to call update_refcount() to do this last step s->free_cluster_index is already pointing to the next cluster after the ones we are trying to allocate. During update_refcount() it may happen however that we also need to allocate a new refcount block in order to store the refcounts of these new clusters (and to complicate things further that may also require us to grow the refcount table). After all this we don't know if the clusters that we originally tried to allocate are still available, so we return -EAGAIN to ask the caller to restart the search for free clusters. This is what can happen in a common scenario: 1) We want to allocate a new cluster and we see that cluster N is free. 2) We try to increase N's refcount but all refcount blocks are full, so we allocate a new one at N+1 (where s->free_cluster_index was pointing at). 3) Once we're done we return -EAGAIN to look again for a free cluster, but now s->free_cluster_index points at N+2, so that's the one we allocate. Cluster N remains unallocated and we have a hole in the qcow2 file. This can be reproduced easily: qemu-img create -f qcow2 -o cluster_size=512 hd.qcow2 1M qemu-io -c 'write 0 124k' hd.qcow2 After this the image has 132608 bytes (256 clusters), and the refcount block is full. If we write 512 more bytes it should allocate two new clusters: the data cluster itself and a new refcount block. qemu-io -c 'write 124k 512' hd.qcow2 However the image has now three new clusters (259 in total), and the first one of them is empty (and unallocated): dd if=hd.qcow2 bs=512c skip=256 count=1 | hexdump -C If we write larger amounts of data in the last step instead of the 512 bytes used in this example we can create larger holes in the qcow2 file. What this patch does is reset s->free_cluster_index to its previous value when alloc_refcount_block() returns -EAGAIN. This way the caller will try to allocate again the original clusters if they are still free. The output of iotest 026 also needs to be updated because now that images have no holes some tests fail at a different point and the number of leaked clusters is different.

2018-03-23target/arm: Always set FAR to a known unknown value for debug exceptionsPeter Maydell1-1/+10
For debug exceptions due to breakpoints or the BKPT instruction which are taken to AArch32, the Fault Address Register is architecturally UNKNOWN. We were using that as license to simply not set env->exception.vaddress, but this isn't correct, because it will expose to the guest whatever old value was in that field when arm_cpu_do_interrupt_aarch32() writes it to the guest IFSR. That old value might be a FAR for a previous guest EL2 or secure exception, in which case we shouldn't show it to an EL1 or non-secure exception handler. It might also be a non-deterministic value, which is bad for record-and-replay. Clear env->exception.vaddress before taking breakpoint debug exceptions, to avoid this minor information leak.

2018-03-23target/arm: Factor out code to calculate FSR for debug exceptionsPeter Maydell2-10/+27
When a debug exception is taken to AArch32, it appears as a Prefetch Abort, and the Instruction Fault Status Register (IFSR) must be set. The IFSR has two possible formats, depending on whether LPAE is in use. Factor out the code in arm_debug_excp_handler() which picks an FSR value into its own utility function, update it to use arm_fi_to_lfsc() and arm_fi_to_sfsc() rather than hard-coded constants, and use the correct condition to select long or short format. In particular this fixes a bug where we could select the short format because we're at EL0 and the EL1 translation regime is not using LPAE, but then route the debug exception to EL2 because of MDCR_EL2.TDE and hand EL2 the wrong format FSR.

2018-03-23target/arm: Honour MDCR_EL2.TDE when routing exceptions due to BKPT/BRKPeter Maydell4-7/+36
The MDCR_EL2.TDE bit allows the exception level targeted by debug exceptions to be set to EL2 for code executing at EL0. We handle this in the arm_debug_target_el() function, but this is only used for hardware breakpoint and watchpoint exceptions, not for the exception generated when the guest executes an AArch32 BKPT or AArch64 BRK instruction. We don't have enough information for a translate-time equivalent of arm_debug_target_el(), so instead make BKPT and BRK call a special purpose helper which can do the routing, rather than the generic exception_with_syndrome helper.

2018-03-23i.MX: Support serial RS-232 break properlyTrent Piepho2-1/+5
Linux does not detect a break from this IMX serial driver as a magic sysrq. Nor does it note a break in the port error counts. The former is because the Linux driver uses the BRCD bit in the USR2 register to trigger the RS-232 break handler in the kernel, which is where sysrq hooks in. The emulated UART was not setting this status bit. The latter is because the Linux driver expects, in addition to the BRK bit, that the ERR bit is set when a break is read in the FIFO. A break should also count as a frame error, so add that bit too.

2018-03-23arm/translate-a64: treat DISAS_UPDATE as variant of DISAS_EXITVictor Kamensky1-3/+3
In OE project 4.15 linux kernel boot hang was observed under single cpu aarch64 qemu. Kernel code was in a loop waiting for vtimer arrival, spinning in TC generated blocks, while interrupt was pending unprocessed. This happened because when qemu tried to handle vtimer interrupt target had interrupts disabled, as result flag indicating TCG exit, cpu->icount_decr.u16.high, was cleared but arm_cpu_exec_interrupt function did not call arm_cpu_do_interrupt to process interrupt. Later when target reenabled interrupts, it happened without exit into main loop, so following code that waited for result of interrupt execution run in infinite loop. To solve the problem instructions that operate on CPU sys state (i.e enable/disable interrupt), and marked as DISAS_UPDATE, should be considered as DISAS_EXIT variant, and should be forced to exit back to main loop so qemu will have a chance processing pending CPU state updates, including pending interrupts. This change brings consistency with how DISAS_UPDATE is treated in aarch32 case.

2018-03-23qapi: Force UTF8 encoding when parsing qapi filesEric Blake1-3/+3
Commit d4e5ec877 already fixed things to work around Python 3's lame bug of having LC_ALL=C not be 8-bit clean, when parsing the main QMP qapi files; but failed to do likewise in the tests directory. As a result, running 'LC_ALL=C make check' fails on escape-too-big and unicode-str when using python 3 with a nasty stack trace instead of the intended graceful error message that QAPI doesn't yet support 8-bit data (the two tests contain Unicode é, when parsed in UTF-8; they represent something different when parsed in a proper single-byte C locale, but that doesn't matter to the error message printed out, provided that brain-dead Python hasn't first choked on the input instead of being 8-bit clean). Ideally, we'd teach the qapi generator scripts to automatically slurp things in using UTF-8 regardless of locale, and to honor content that is not limited to 7 bit data rather than gracefully erroring out; but until then, since our graceful error depends on python parsing 8-bit data (even if nothing we generate uses 8-bit data), our quick fix is to use the right locale when running these tests.

2018-03-23Revert "monitor: enable IO thread for (qmp & !mux) typed"Peter Xu2-13/+2
This reverts commit 3fd2457d18edf5736f713dfe1ada9c87a9badab1. Enabling OOB caused several iotests failures; due to the imminent 2.12 release, the safest action is to disable OOB for now. If other patches fix the issues that iotests exposed, it may be turned back on in time for the release, otherwise it will be 2.13 material; either way, the framework changes not reverted now do not hurt if they remain as part of the 2.12 release. Additionally, revert the tests in the patch 02130314d8 ("qmp: introduce QMPCapability", 2018-03-19), as both parts must be reverted at once to keep 'make check' passing.

2018-03-23migration: convert socket server to QIONetListenerDaniel P. Berrange1-32/+16
Instead of creating a QIOChannelSocket directly for the migration server socket, use a QIONetListener. This provides the ability to listen on multiple sockets at the same time, so enables full support for IPv4/IPv6 dual stack. For example, '$QEMU -incoming tcp::9000' now correctly listens on both 0.0.0.0 and :: at the same time, instead of only on 0.0.0.0. Signed-off-by: Daniel P.

2018-03-23make: switch from -I to -iquoteMichael S. Tsirkin3-11/+11
Our rule right now is to use <> for external headers, "" for internal ones. The idea was to avoid conflicts between e.g. a system file named <trace.h> and an internal one by the same name. Unfortunately we use -I compiler flag so it does not help: a system file doing #include <trace.h> will still pick up ours first. To fix, switch to -iquote which is supported by both gcc and clang and only affects #include "" directives. As a side effect, this catches any future uses of #include <> for internal headers.
