2018-01-29tpm: add CRB deviceMarc-André Lureau
tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB) Interface as defined in TCG PC Client Platform TPM Profile (PTP) Specification Family “2.0” Level 00 Revision 01.03 v22. The PTP allows device implementation to switch between TIS and CRB model at run time, but given that CRB is a simpler device to implement, I chose to implement it as a different device. The device doesn't implement other locality than 0 for now (my laptop TPM doesn't either, so I assume this isn't so bad) Tested with some success with Linux upstream and Windows 10, seabios & modified ovmf. The device is recognized and correctly transmit command/response with passthrough & emu. However, we are missing PPI ACPI part atm.

2017-07-20tests: Handle $RANDOM not being supported by the shellPeter Maydell
In various places in our test makefiles and scripts we use the shell $RANDOM to create a random number. This is a bash specific extension, and doesn't work on other shells. With dash the shell doesn't complain, it just effectively always evaluates $RANDOM to 0: echo $((RANDOM + 32768)) => 32768 However, on NetBSD the shell will complain: "-sh: arith: syntax error: "RANDOM + 32768" which means that "make check" fails. Switch to using "${RANDOM:-0}" instead of $RANDOM, which will portably either give us a random number or zero. This means that on non-bash shells we don't get such good test coverage via the MALLOC_PERTURB_ setting, but we were already in that situation for non-bash shells. Our only other uses of $RANDOM (in tests/qemu-iotests/check and tests/qemu-iotests/162) are in shell scripts which use a #!/bin/bash line so they are always run under bash.

2017-05-31qapi: Reject alternates that can't work with keyval_parse()Markus Armbruster
Alternates are sum types like unions, but use the JSON type on the wire / QType in QObject instead of an explicit tag. That's why we require alternate members to have distinct QTypes. The recently introduced keyval_parse() (commit d454dbe) can only produce string scalars. The qobject_input_visitor_new_keyval() input visitor mostly hides the difference, so code using a QObject input visitor doesn't have to care whether its input was parsed from JSON or KEY=VALUE,... The difference leaks for alternates, as noted in commit 0ee9ae7: a non-string, non-enum scalar alternate value can't currently be expressed. In part, this is just our insufficiently sophisticated implementation. Consider alternate type 'GuestFileWhence'. It has an integer member and a 'QGASeek' member. The latter is an enumeration with values 'set', 'cur', 'end'. The meaning of b=set, b=cur, b=end, b=0, b=1 and so forth is perfectly obvious. However, our current implementation falls apart at run time for b=0, b=1, and so forth. Fixable, but not today; add a test case and a TODO comment. Now consider an alternate type with a string and an integer member. What's the meaning of a=42? Is it the string "42" or the integer 42? Whichever meaning you pick makes the other inexpressible. This isn't just an implementation problem, it's fundamental. Our current implementation will pick string. So far, we haven't needed such alternates. To make sure we stop and think before we add one that cannot sanely work with keyval_parse(), let's require alternate members to have sufficiently distinct representation in KEY=VALUE,... syntax: * A string member clashes with any other scalar member * An enumeration member clashes with bool members when it has value 'on' or 'off'. * An enumeration member clashes with numeric members when it has a value that starts with '-', '+', or a decimal digit. This is a rather lazy approximation of the actual number syntax accepted by the visitor. Note that enumeration values starting with '-' and '+' are rejected elsewhere already, but better safe than sorry.

2017-04-26tests: Add a tester for HMP commandsThomas Huth
HMP commands do not get any automatic testing yet, so on certain QEMU machines, some HMP commands were causing crashes in the past. Thus we should test HMP commands in our test suite, too, to avoid that such problems creep in again in the future.

Currently all trace.o are linked into qemu-system, qemu-img, qemu-nbd, qemu-io etc., even the corresponding components are not included. Put all trace.o into libqemuutil.a that the linker would only pull in .o files containing symbols that are actually referenced by the program.
