0eb4d4eee1 ipmi_bmc_sim: Remove an unnecessary mutex
Get rid of the unnecessary mutex, it was a vestige
of something else that was not done.  That way we don't
have to free it.

9c5ce8db2e vl: Switch qemu_uuid to QemuUUID
Update all qemu_uuid users as well, especially get rid of the duplicated
low level g_strdup_printf, sscanf and snprintf calls with QEMU UUID API.

Since qemu_uuid_parse is quite tangled with qemu_uuid, its switching to
QemuUUID is done here too to keep everything in sync and avoid code
churn.

5167560b03 ipmi: add some local variables in ipmi_sdr_init
This patch adds a couple of variables to manipulate the raw sdr
entries. The const attribute is also removed on init_sdrs. This will
ease the introduction of a sdr loader using a file.

52fc01d973 ipmi: remove the need of an ending record in the SDR table
Currently, the code initializing the sdr table relies on an ending
record with a recid of 0xffff. This patch changes the loop to use the
sdr size as a breaking condition.

a580d82085 ipmi: replace IPMI_ADD_RSP_DATA() macro with inline helpers
The IPMI command handlers in the BMC simulator use a macro
IPMI_ADD_RSP_DATA() to push bytes in a response buffer. The macro
hides the fact that it implicitly uses variables local to the handler,
which is misleading.

This patch introduces a simple 'struct RspBuffer' and inlined helper
routines to store byte(s) in a response buffer. rsp_buffer_push()
replaces the macro IPMI_ADD_RSP_DATA() and rsp_buffer_pushmore() is
new helper to push multiple bytes. The latest is used in the command
handlers get_msg() and get_sdr() which are manipulating the buffer
directly.

4f298a4b29 ipmi: remove IPMI_CHECK_CMD_LEN() macro
Most IPMI command handlers in the BMC simulator start with a call to
the macro IPMI_CHECK_CMD_LEN() which verifies that a minimal number of
arguments expected by the command are indeed available. To achieve
this task, the macro implicitly uses local variables which is
misleading in the code.

This patch adds a 'cmd_len_min' attribute to the struct IPMICmdHandler
defining the minimal number of arguments expected by the command and
moves this check in the global command handler ipmi_sim_handle_command().

To clarify the checks being done on the received command, the patch
introduces a helper ipmi_get_handler().

It was falling through when it should have been a break.  Found by
Coverity.  The logic could be simplified a bit with a fallthrough,
probably the original thought, but that would be less clear, I think.

a2295f0a58 ipmi: introduce a struct ipmi_sdr_compact
Currently, sdr attributes are identified using byte offsets and this
can be a bit confusing.

This patch adds a struct ipmi_sdr_compact conforming to the IPMI specs
and replaces byte offsets with names. It also introduces and uses a
struct ipmi_sdr_header in sections of the code where no assumption is
made on the type of SDR. This leave rooms to potential usage of other
types in the future.

792afddb4a ipmi: fix SDR length value
The IPMI BMC simulator populates the SDR table with a set of initial
SDRs. The length of each SDR is taken from the record itself (byte 4)
which does not include the size of the header. But, the full length
(header + data) is required by the sdr_add_entry() routine.

d13ada5d8f ipmi: replace goto by a return statement
Each routine using the IPMI_ADD_RSP_DATA, IPMI_CHECK_CMD_LEN or
IPMI_CHECK_RESERVATION macros needs to define a goto label 'out' to
handle hidden errors. Using directly a return statement has the same
effect and it removes the fact that 'out' needs to be defined.

The code exits in ipmi_sim_handle_command() are a little different
from the rest and a "possible" error in the macro IPMI_ADD_RSP_DATA is
handled before making use of it. This might be a bit excessive as a
minimum response len is currently 300 bytes and the patch checks that
at least 3 are available.
