2018-02-09Include qapi/error.h exactly where neededMarkus Armbruster
This cleanup makes the number of objects depending on qapi/error.h drop from 1910 (out of 4743) to 1612 in my "build everything" tree. While there, separate #include from file comment with a blank line, and drop a useless comment on why qemu/osdep.h is included first.

2017-12-05smbios: support setting OEM strings tableDaniel P. Berrange
The cloud-init program currently allows fetching of its data by repurposing of the 'system' type 'serial' field. This is a clear abuse of the serial field that would clash with other valid usage a virt management app might have for that field. Fortunately the SMBIOS defines an "OEM Strings" table whose puporse is to allow exposing of arbitrary vendor specific strings to the operating system. This is perfect for use with cloud-init, or as a way to pass arguments to OS installers such as anaconda. This patch makes it easier to support this with QEMU. e.g. $QEMU -smbios type=11,value=Hello,value=World,value=Tricky,,value=test Which results in the guest seeing dmidecode data Handle 0x0E00, DMI type 11, 5 bytes OEM Strings String 1: Hello String 2: World String 3: Tricky,value=test It is suggested that any app wanting to make use of this OEM strings capability for accepting data from the host mgmt layer should use its name as a string prefix. e.g. to expose OEM strings targetting both cloud init and anaconda in parallel the mgmt app could set $QEMU -smbios type=11,value=cloud-init:ds=nocloud-net;s=http://10.10.0.1:8000/,\ value=anaconda:method=http://dl.fedoraproject.org/pub/fedora/linux/releases/25/x86_64/os which would appear as Handle 0x0E00, DMI type 11, 5 bytes OEM Strings String 1: cloud-init:ds=nocloud-net;s=http://10.10.0.1:8000/ String 2: anaconda:method=http://dl.fedoraproject.org/pub/fedora/linux/releases/25/x86_64/os Use of such string prefixes means the app won't have to care which string slot its data appears in.

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.

2016-09-23util: Add UUID APIFam Zheng
A number of different places across the code base use CONFIG_UUID. Some of them are soft dependency, some are not built if libuuid is not available, some come with dummy fallback, some throws runtime error. It is hard to maintain, and hard to reason for users. Since UUID is a simple standard with only a small number of operations, it is cleaner to have a central support in libqemuutil. This patch adds qemu_uuid_* functions that all uuid users in the code base can rely on. Except for qemu_uuid_generate which is new code, all other functions are just copy from existing fallbacks from other files. Note that qemu_uuid_parse is moved without updating the function signature to use QemuUUID, to keep this patch simple.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
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. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Done with this Coccinelle semantic patch: @@ type T; identifier FUN, RET; expression list ARGS; expression ERR, EC; @@ ( - T RET = FUN(ARGS, &ERR); + T RET = FUN(ARGS, &error_fatal); | - RET = FUN(ARGS, &ERR); + RET = FUN(ARGS, &error_fatal); | - FUN(ARGS, &ERR); + FUN(ARGS, &error_fatal); ) - if (ERR != NULL) { - error_report_err(ERR); - exit(EC); - } This is actually a more elegant version of my initial semantic patch by courtesy of Eduardo.
