found some cases where the output ended up not looking as expected. So
the following changes are in the patch below:
- if the protocol ID in the MAC header is an integer, just write it into
the datastructure without trying to find a corresponding string for it
and if none is found failing
- when writing the protocol ID as string, simply write it as integer if
no corresponding string can be found
- same changes for arpOpcode parsing and printing
- same changes for protocol ID in an IP packet
- DSCP value needs to be written into the data structure
- IP protocol version number is redundant at this level, so remove it
- parse the protocol ID found inside an IP packet not only as string but
also as uint8
- arrange the display of the src and destination masks to be shown after
the src and destination ip address respectively in the XML
- the existing libvirt IP address parser accepts for example '25' as an
IP address. I want this to be parsed as a CIDR type netmask. So try to
parse it as an integer first (CIDR netmask) and if that doesn't work as
a dotted IP address style netmask.
- instantiation of rules with MAC masks didn't work because they weren't
printed into a buffer, yet.

Add missing source to the proxy and disable XML parsing code in
nwfilter_params.c for a proxy build.
* cfg.mk (sc_prohibit_test_minus_ao): Also check for [.
* docs/Makefile.am (%.html, html/index.html): Avoid non-portable
test usage.
* libvirt.spec.in (%post): Likewise.
* tools/virt-pki-validate.in (servercert.pem): Likewise.
* configure.ac (LOGNAME): Use test, not [, in files processed by
autoconf.
Detected by Matthias Bolte.
virStrToLong* guarantees (via strtol) that the end pointer will be set
to the point at which parsing stopped (even on failure, this point is
the start of the input string).
* src/esx/esx_driver.c (esxGetVersion): Remove pointless
conditional.
* src/qemu/qemu_conf.c (qemuParseCommandLinePCI)
(qemuParseCommandLineUSB, qemuParseCommandLineSmp): Likewise.
* src/qemu/qemu_monitor_text.c
(qemuMonitorTextGetMigrationStatus): Likewise.
Call me lazy: some shells use exit (e.g. sh), others use quit (e.g. ftp),
but I never remember which. So it's faster to write a patch to make
virsh take both than it is to take a 50-50 guess, and get it wrong
in half of my attempts.
* tools/virsh.c (commands): Add 'exit'.
* tools/virsh.pod: Document it.
Check that interface names only contain valid characters. Blank them out
otherwise.
Valid characters in this code are currently a-z,A-Z,0-9, '-' and '_'.
The Python script generates the mappings based on the type descriptions
in the esx_vi_generator.input file.
This also improves the inheritance handling and allows to get rid of the
ugly, inflexible, and error prone _base/_super approach. Now every struct
that represents a SOAP type contains a _type member, that allows to
recreate C++-like dynamic dispatch for "method" calls in C.
* examples/xml/nwfilter/Makefile.am: add all xml to the distribution
* libvirt.spec.in: reference them from the rpm spec file to have them
available in the main libvirt package
* src/Makefile.am: adds a few missing header files in the associated
file variables, it's needed otherwise the missing headers breaks
compilation from a distribution tarball
Automate the reuse of autogen.sh, rather than just erroring out.
* cfg.mk (_update_required): Run autogen.sh, rather than just
warning about it.
(_autogen): New target.
This patch changes the network filtering code to use libvirt's existing
IPv4 and IPv6 address parsers/printers rather than my self-written ones.
I am introducing a new function in network.c that counts the number of
bits in a netmask and ensures that the given address is indeed a netmask,
return -1 on error or values of 0-32 for IPv4 addresses and 0-128 for
IPv6 addresses. I then based the function checking for valid netmask
on invoking this function.
This patch adds IPv6 filtering support for the following protocols:
- tcp-ipv6
- udp-ipv6
- udplite-ipv6
- esp-ipv6
- ah-ipv6
- sctp-ipv6
- all-ipv6
- icmpv6
Many of the IPv4 data structure could be re-used for IPv6 support.
Since ip6tables also supports pretty much the same command line parameters
as iptables does, also much of the code could be re-used and now
command lines are invoked with the ip(6)tables tool parameter passed
through the functions as a parameter.
This patch removes the driver dependency from nwfilter_conf.c and moves
a callback function calling into the driver into
nwfilter_gentech_driver.c and passes a pointer to that callback function
upon initialization of nwfilter_conf.c.
Since the timers are defined to cover all possible config cases for
several different hypervisors, many of these possibilities generate an
error on qemu. Here is what is currently supported:
RTC: If the -rtc commandline option is available, allow setting
"clock=host"
or "clock=vm" based on the rtc timer clock='host|guest' value. Also
add "driftfix=slew" if the tickpolicy is 'catchup', or add nothing
if
tickpolicy is 'delay'. (Other tickpolicies will raise an error).
If -rtc isn't available, but -rtc-td-hack is, add that option
if the tickpolicy is 'catchup', add -rtc-td-hack, if it is 'delay'
add nothing, and if it's anything else, raise an error.
PIT: If -no-kvm-pit-reinjection is available, and tickpolicy is
'delay', add that option. if tickpolicy is 'catchup', do
nothing. Anything else --> raise an error.
If -no-kvm-pit-reinjection *isn't* available, but -tdf is, when
tickpolicy is 'catchup' add -tdf. If it's 'delay', do
nothing. Anything else --> raise an error.
If neither of those commandline options is available, and
tickpolicy is anything other than 'delay' (or unspecified), raise
an error.
HPET: If -no-hpet flag is available and present='no', add -no-hpet.
If -no-hpet is not available, and present='yes', raise an error.
If present is unspecified, the default is to do whatever this
particular qemu does by default, so don't raise an error.
All other timer types are unsupported by QEMU, so they will raise an
error.
* src/qemu/qemu_conf.c: extend qemuBuildClockArgStr() to generate the
command line arguments for the new options
* src/qemu/qemu_conf.h: define 4 new flags
* src/qemu/qemu_conf.c: check the help text of qemu for presence of
features indicated by each flag.
* tests/qemuhelptest.c: add appropriate flags into the masks for each test
timers are sub-elements of clocks. A clock can have zero or more
instances of timer. Within the timer, only the name attribute is
required; all other attributes are optional.
A simpler representation of a timer element is:
<timer name='platform|pit|rtc|hpet|tsc'
wallclock='host|guest'
tickpolicy='delay|catchup|merge|discard'
frequency='123'
mode='auto|native|emulate|paravirt'
present='yes|no'/>
frequency is a ulong. All other attributes are simple enums.
This extension is described in
http://www.redhat.com/archives/libvir-list/2010-March/msg00304.html
Currently all attributes are optional, except name.
* src/conf/domain_conf.h: add data definition for virDomainTimerDef
and add a list of them to virDomainClockDef
* src/conf/domain_conf.c: XML parser and formatter for a timer inside a clock
* src/libvirt_private.syms: add new Timer enum helper functions to symbols
The QEMU cpu affinity is used in NUMA scenarios to ensure that
guest memory is allocated from a specific node. Normally memory
is allocate on demand in vCPU threads, but when using hugepages
the initial thread leader allocates memory upfront. libvirt was
not setting affinity of the thread leader, or I/O threads. This
patch changes the code to set the process affinity in between
the fork()/exec() of QEMU. This ensures that every single QEMU
thread gets the affinity
* src/qemu/qemu_driver.c: Set affinity on entire QEMU process
at startup
Common Unix practice is to prefer VISUAL over EDITOR, particularly if
the editor of choice spawns a new window. Thus, it is also common to
see settings like EDITOR='emacs -nw', with the expectation that the
shell will parse this as an argument to 'emacs' and not try to invoke
a file containing a space.
If a user puts junk in EDITOR, they deserve what they get (much more
than virsh will misbehave); furthermore, sudo scrubs EDITOR by
default. So the blind use of metacharacters in EDITOR should not be
considered too much of a security issue.
* tools/virsh.c (editFile): Prefer VISUAL over EDITOR. Don't
reject shell metacharacters in EDITOR.
* tools/virsh.pod (edit, net-edit, ENVIRONMENT): Document VISUAL.

This patch fixes the 'make check' runs for me which, under certain
circumstances and login configurations, did invoke popups requesting
authentication. I removed the parameter conn from being passed into the
error reporting function.
* src/conf/nwfilter_conf.h src/conf/nwfilter_conf.c: remove conn from
error reporting parameters.
Right now this implements only 2 basic hooks:
- before the lxc control process is being launched
- after the lxc control process is terminated
the XML description of the domain is passed to the hook script stdin
/etc/libvirt/hook/lxc
* src/lxc/lxc_driver.c: implement synchronous script hooks for LXC
at domain startup and end
Right now this implements only 2 basic hooks:
- before the qemu process is being launched
- after the qemu process is terminated
the XML description of the domain is passed to the hook script stdin
/etc/libvirt/hook/qemu
* src/qemu/qemu_driver.c: implement synchronous script hooks for QEmu
at domain startup and end
It supports 3 kind of probing times, at daemon startup, when the
daemon reloads its drivers on SIGHUP and when the daemon exits
* daemon/libvirtd.c: daemon hooks for startup, reload and exit
This exports 3 basic routines:
- virHookInitialize() initializing the hook support by looking for
scripts availability
- virHookPresent() used to test if there is a hook for a given driver
- virHookCall() which actually calls a synchronous script hook with
the needed parameters
Note that this doesn't expose any public API except for the locations
and arguments passed to the scripts
* src/Makefile.am: add the 2 new files
* src/util/hooks.h src/util/hooks.c: implements the 3 functions
* src/libvirt_private.syms: export the 3 symbols internally
* po/POTFILES.in: add src/util/hooks.c to translatables modules
used to read the data from virExec stdout/err file descriptors
* src/util/util.c src/util/util.h: not static anymore and export it
* src/libvirt_private.syms: allow access internally
This flag is used in migration prepare step to send updated XML
definition of a guest.
Also ``virsh dumpxml --update-cpu [--inactive] guest'' command can be
used to see the updated CPU requirements.
Useful mainly for migration. cpuUpdate changes guest CPU requirements in
the following way:
- match == "strict" || match == "exact"
- optional features which are supported by host CPU are changed into
required features
- optional features which are not supported by host CPU are disabled
- all other features remain untouched
- match == "minimum"
- match is changed into "exact"
- optional features and all features not mentioned in guest CPU
specification which are supported by host CPU become required
features
- other optional features are disabled
- all other features remain untouched
This ensures that no feature will suddenly disappear from the guest
after migration.
When a domain is defined on host1, migrated to host2 and then migrated
back to host1, its current configuration would overwrite the libvirtd's
in-memory copy of persistent configuration of that domain. This is not
desired as we want to preserve the persistent configuration untouched.
This patch introduces new 'live' parameter to virDomainAssignDef.
Passing 'true' for 'live' means the configuration passed to
virDomainAssignDef describes a configuration of live instance of the
domain. This applies for saved domains which are being restored or for
incoming domains during migration.
All callers have been changed to pass the appropriate value.
