The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

The output buffer for virFileReadAll was too small for systems with
more than 30 CPUs which leads to a log entry and incorrect behavior.
The new size will be sufficient for the current
architectural limits.

This patch removes the explicit FSF address, and uses above instead

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:
src/security/security_selinux.h
src/security/security_driver.h
src/security/security_selinux.c
src/security/security_apparmor.h
src/security/security_apparmor.c
src/security/security_driver.c
This removes nearly all the per-file error reporting macros
from the code in src/util/. A few custom macros remain for the
case, where the file needs to report errors with a variety of
different codes or parameters

In order to retrieve some sysinfo data we need to parse /proc/sysinfo and
/proc/cpuinfo.

Libvirt on x86 parses 'dmidecode' to gather characteristics of host
system. On PowerPC, this is now implemented by reading /proc/cpuinfo
NOTE: memory-DIMM information is not presently implemented.

Now that no one is relying on the return value being a pointer to
somewhere inside of the passed-in argument, we can simplify the
callers to simply return success or failure. Also wrap some long
lines and add some const-correctness.
* src/util/sysinfo.c (virSysinfoParseBIOS, virSysinfoParseSystem)
(virSysinfoParseProcessor, virSysinfoParseMemory): Change return.
(virSysinfoRead): Adjust caller.
dmidecode displays processor information, followed by BIOS, system and
memory-DIMM details.
Calls to virSysinfoParseBIOS(), virSysinfoParseSystem() would update
the buffer pointer 'base', so the processor information would be lost
before virSysinfoParseProcessor() was called. Sysinfo would therefore
not be able to display processor details -- It only described <bios>,
<system> and <memory_device> details.
This patch attempts to insulate sysinfo from ordering of dmidecode
output.
Before the fix:
---------------
virsh # sysinfo
<sysinfo type='smbios'>
<bios>
....
</bios>
<system>
....
</system>
<memory_device>
....
</memory_device>
After the fix:
-------------
virsh # sysinfo
<sysinfo type='smbios'>
<bios>
....
</bios>
<system>
....
</system>
<processor>
....
</processor>
<memory_device>
....
</memory_device>
The improvements to virBuffer, along with a paradigm shift to pass
the original buffer through rather than creating a second buffer,
allow us to shave off quite a few lines of code.
* src/util/sysinfo.h (virSysinfoFormat): Alter signature.
* src/util/sysinfo.c (virSysinfoFormat, virSysinfoBIOSFormat)
(virSysinfoSystemFormat, virSysinfoProcessorFormat)
(virSysinfoMemoryFormat): Change indentation parameter.
* src/conf/domain_conf.c (virDomainSysinfoDefFormat): Adjust
caller.
* src/qemu/qemu_driver.c (qemuGetSysinfo): Likewise.
DMI table is Intel & Intel-compatible specific. Therefore other
architectures miss dmidecode command. So we always fail in searching
for that command on non-Intel architectures.
Detected by Coverity. No real harm in leaving these, but fixing
them cuts down on the noise for future analysis.
* src/rpc/virnetserver.c (virNetServerAddService): Delete unused
entry.
* src/util/sysinfo.c (virSysinfoRead): Delete dead assignment to
base.
Detected by gcc -O2, introduced in commit 532ce9c2. If dmidecode
outputs a field unrecognized by the parsers, then the code would
dereference an uninitialized eol variable.
* src/util/sysinfo.c (virSysinfoParseBIOS)
(virSysinfoParseSystem, virSysinfoParseProcessor)
(virSysinfoParseMemory): Avoid uninitialized variable.
The virSysinfoIsEqual method was mistakenly inside a #ifndef WIN32
conditional.
The existing virSysinfoFormat is also stubbed out on Win32, even
though the code works without any trouble. This breaks XML output
on Win32, so the stub is removed.
virsh migrate mistakenly had some variables inside the conditional
* src/util/sysinfo.c: Build virSysinfoIsEqual on Win32 and remove
Win32 stub for virSysinfoFormat
* tools/virsh.c: Fix variable declaration on Win32
To allow a client app to pass in custom XML during migration
of a guest it is neccessary to ensure the guest ABI remains
unchanged. The virDomainDefCheckABIStablity method accepts
two virDomainDefPtr structs and compares everything in them
that could impact the guest machine ABI
* src/conf/domain_conf.c, src/conf/domain_conf.h,
src/libvirt_private.syms: Add virDomainDefCheckABIStablity
* src/conf/cpu_conf.c, src/conf/cpu_conf.h: Add virCPUDefIsEqual
* src/util/sysinfo.c, src/util/sysinfo.h: Add virSysinfoIsEqual
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose. Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.
global rename performed with:
$ git grep -l virBufferVSprintf \
| xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'
then revert the changes in ChangeLog-old.
Move existing routines about virSysinfoDef to an util module,
add a new entry point virSysinfoRead() to read the host values
with dmidecode
* src/conf/domain_conf.c src/conf/domain_conf.h src/util/sysinfo.c
src/util/sysinfo.h: move to a new module, add virSysinfoRead()
* src/Makefile.am: handle the new module build
* src/libvirt_private.syms: new internal symbols
* include/libvirt/virterror.h src/util/virterror.c: defined a new
error code for that module
* po/POTFILES.in: add new file for translations
