2017-07-14qom: enforce readonly nature of link's check callbackIgor Mammedov1-1/+1
link's check callback is supposed to verify/permit setting it, however currently nothing restricts it from misusing it and modifying target object from within. Make sure that readonly semantics are checked by compiler to prevent callback's misuse.

2017-06-02char: move CharBackend handling in char-fe unitMarc-André Lureau1-1/+1
Move all the frontend struct and methods to a seperate unit. This avoids accidentally mixing backend and frontend calls, and helps with readabilty. Make qemu_chr_replay() a macro shared by both char and char-fe. Export qemu_chr_write(), and use a macro for qemu_chr_write_all() (nb: yes, CharBackend is for char frontend :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake1-2/+2
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

This patch provides a simple FRU support for the BMC simulator. FRUs are loaded from a file which name is specified in the object properties, each entry having a fixed size, also specified in the properties. If the file is unknown or not accessible for some reason, a unique entry of 1024 bytes is created as a default. Just enough to start some simulation. These commands complies with the IPMI spec : "34.

The member VMStateField.start is used for two things, partial data migration for VBUFFER data (basically provide migration for a sub-buffer) and for locating next in QTAILQ. The implementation of the VBUFFER feature is broken when VMSTATE_ALLOC is used. This however goes unnoticed because actually partial migration for VBUFFER is not used at all.

The continue_send() method in ipmi_bmc_extern.c directly assigns the return value of qemu_chr_fe_write() to the variable tracking the I/O buffer offset. This ignores the possibility that the return value could be -1 and so will cause I/O go backwards on EAGAIN.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

2016-02-09ipmi: do not take/drop iothread lockPaolo Bonzini1-2/+0
This is not necessary and actually causes a hang; it was probably copied and pasted from KVM code, that is one of the very few places that run outside iothread lock. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-02-06ipmi: add ACPI power and GUID commandsCédric Le Goater1-0/+49
>From the specs (20.8 Get Device GUID Command), the command needs to return a GUID (Globally Unique ID), or UUID, that should never change over the lifetime of the device. qemu_uuid looked like a good candidate to start with but we could use a specific BMC property also if needed.

2016-02-06ipmi: introduce a struct ipmi_sdr_compactCédric Le Goater1-28/+44
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.

2016-02-06ipmi: fix SDR length valueCédric Le Goater1-6/+6
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. Signed-off-by: Cédric Le Goater <clg@fr.ibm.com> Acked-by: Michael S.

2016-02-06ipmi: replace goto by a return statementCédric Le Goater1-99/+41
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.

2016-01-22fpu: Replace int32 typedef with int32_tPeter Maydell2-2/+2
Replace the int32 softfloat-specific typedef with int32_t. This change was made with find hw include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint32\b/int32_t/g' together with manual removal of the typedef definition, and manual undoing of some mis-hits where macro arguments were being used for token pasting rather than as a type. The uses in hw/ipmi/ should not have been using this type at all.
