2012-10-27Makefile: Forbid out-of-tree build from a source tree that has been built inPeter Maydell1-0/+11
If we try to do an out-of-tree build but the source tree we're building from has been used in the past for an in-tree build then things will go confusingly wrong. Specifically, some parts of the build process will pull in generated files from the old in-tree build (because SRC_PATH is on the vpath). Diagnose this situation so we can produce a useful error message and tell the user how to fix it (run distclean in the source tree).

2012-10-27configure: Disable (clang) initializer-overrides warningsPeter Maydell1-0/+1
Disable clang's initializer-overrides warnings, as QEMU makes significant use of the pattern of initializing an array with a range-based default entry like [0 ... 0x1ff] = { GPIO_NONE, 0 } followed by specific entries which override that default, and clang would otherwise warn "initializer overrides prior initialization of this subobject" when it encountered the specific entry.

Remove an out of date FIXME regarding the saturating arithmetic helpers: we now do pass a pointer to CPUARMState to these helpers, and since the AREG0 changes went in there is no difference between helper.c and op_helper.c and therefore no point in moving the functions.

2012-10-23qmp: add NBD server commandsPaolo Bonzini4-1/+179
Adding an NBD server inside QEMU is trivial, since all the logic is in nbd.c and can be shared easily between qemu-nbd and QEMU itself. The main difference is that qemu-nbd serves a single unnamed export, while QEMU serves named exports.

2012-10-23qemu-sockets: add error propagation to inet_connect_addrPaolo Bonzini1-9/+6
perror and fprintf can be removed because all clients can now consume Errors properly. However, we'll need to change the non-blocking connect handlers to take an Error, in order to improve error handling for migration with the TCP protocol. This is a minor degradation in error reporting for outgoing migration. However, until 1.2 this case just failed without even attempting to connect, so it is still an improvement as far as overall QoI is concerned.

2012-10-23migration (outgoing): add error propagation for all protocolsPaolo Bonzini6-65/+22
Error propagation is already there for socket backends. Add it to other protocols, simplifying code that tests for errors that will never happen. With all protocols understanding Error, the code can be simplified further by removing the return value. Unfortunately, the quality of error messages varies depending on where the error is detected, because no Error is passed to the NonBlockingConnectHandler. Thus, the exact error message still cannot be sent to the user if the OS reports it asynchronously via SO_ERROR. If NonBlockingConnectHandler received an Error**, we could for example report the error class and/or message via a new field of the query-migration command even if it is reported asynchronously.

2012-10-23migration: avoid using error_is_set and thus relying on errp != NULLPaolo Bonzini2-9/+12
The migration code is using errp to detect "internal" errors, this means that it relies on errp being non-NULL. No impact so far because our only QMP clients (the QMP marshaller and HMP) never pass a NULL Error **. But if we had others, this patch would make sure that migration can work with a NULL Error **.
