A missing shell was noisy, and the use of command to decipher a
shell's absolute path requires "" rather than ''.
* configure.ac (lv_cv_wrapper_shell): Fix logic errors if candidate
shell is not available.
* .gitignore: Ignore file created when /bin/sh is old dash.
Reported by Matthias Bolte.
* cfg.mk (sc_prohibit_trailing_blank_lines): Delete; this is
adequately covered by maint.mk's sc_prohibit_empty_lines_at_EOF.
* .x-sc_prohibit_empty_lines_at_EOF: New file, to exempt raw
patches.
* Makefile.am (EXTRA_DIST): Include new exemption.
When using 0-prefixed numbers, QEmu will interpret them as octal numbers
(as C convention says); this means that if you attach a device that has
addr > 10 (decimal) you're going to attach a different device.
* tools/virsh.c (opts_freecell, opts_memtune, opts_vcpupin)
(opts_setvcpus, opts_setmaxmem, opts_setmem)
(opts_migrate_setmaxdowntime): Use VSH_OT_INT when only an integer
is expected.
(vshCmddefHelp, vshCmddefGetData): Allow mandatory VSH_OT_INT
arguments.
Older dash mistakenly truncates regular files when using <> redirection;
this kills our use of double dd to reduce storage overhead when
saving qemu images. But qemu insists on running a command through
/bin/sh, so we work around it by having qemu run $sh -c 'real command'
when we have a replacement $sh in mind.
* configure.ac (VIR_WRAPPER_SHELL): Define to a replacement shell,
if /bin/sh is broken on <> redirection.
* src/qemu/qemu_monitor.h (VIR_WRAPPER_SHELL_PREFIX)
(VIR_WRAPPER_SHELL_SUFFIX): New macros.
* src/qemu/qemu_monitor_text.c (qemuMonitorTextMigrateToFile): Use
them.
* src/qemu/qemu_monitor_json.c (qemuMonitorJSONMigrateToFile):
Likewise.
The default location for the XML catalog file, /etc/xml/catalog,
used when validating the generated html docs, isn't correct for
MacOS X.
This commit adds an option to the configure script, allowing the
default to be overridden:
--with-xml-catalog-file=/path/to/xml/catalog/file
When failing to start a virtual network, we have to cleanup,
tearing down any iptables rules. If the iptables rules were
not present yet though, this raises an error, which squashes
the original error we were handling.
* src/network/bridge_driver.c: When failing to start a virtual
network, don't squash the original error in cleanup
Previously, only the API docs were installed, rather than the
complete documentation set. This commit ensures the complete
documentation set is installed.
With SystemTap 1.0 a part of the generated macros in probes.h
expands to:
volatile __typeof__(((name))) arg2 = (name);
GCC reports an 'invalid initialize' error when name has type
char[]. Therfore, add casts to char* to avoid this.
The network address was being set to 192.168.122.0 instead
of 192.168.122.0/24. Fix this by removing the unneccessary
'network' field from virNetworkDef and just pass the
network address and netmask into the iptables APIs directly.
* src/conf/network_conf.h, src/conf/network_conf.c: Remove
the 'network' field from virNEtworkDef.
* src/network/bridge_driver.c: Update for iptables API changes
* src/util/iptables.c, src/util/iptables.h: Require the
network address + netmask pair to be passed in
* tools/virsh.c: add missing option from the CLI to allows setting
up the NIC model type when attaching an interface
* tools/virsh.pod: extend documentation
* AUTHORS: add Osier Yang to the list
So far, readonly=on option is used when qemu supports -device. However,
there are qemu versions which support readonly option with -drive
although they don't have support for -device.
This 1-liner was actually written by Eric Blake, over IRC. It
addresses a compilation failure in make dist and make rpm for
systems without the dtrace/systemtap development libraries
installed.
The boot server IP address is optional, so it needs to be
checked before attempting to parse it.
* src/conf/network_conf.c: Don't parse NULL ip address for
boot server
Instead of storing the IP address string in virNetwork related
structs, store the parsed virSocketAddr. This will make it
easier to add IPv6 support in the future, by letting driver
code directly check what address family is present
* src/conf/network_conf.c, src/conf/network_conf.h,
src/network/bridge_driver.c: Convert to use virSocketAddr
in virNetwork, instead of char *.
* src/util/bridge.c, src/util/bridge.h,
src/util/dnsmasq.c, src/util/dnsmasq.h,
src/util/iptables.c, src/util/iptables.h: Convert to
take a virSocketAddr instead of char * for any IP
address parameters
* src/util/network.h: Add macros to determine if an address
is set, and what address family is set.
It is useful to know where the client is connecting from,
so include the socket address in probe data.
* daemon/libvirtd.h: Use virSocketAddr for storing client
address and keep printable address handy for logging
* daemon/libvirtd.c: Include socket address in client
connect/disconnect probes
* daemon/probes.d: Add socket address to probes
* examples/systemtap/client.stp: Print socket address
* src/util/network.h: Add sockaddr_un to virSocketAddr union
Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.
This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).
# stap examples/systemtap/client.stp
Client fd=44 connected readonly=0
Client fd=44 auth polkit deny pid:24997,uid:500
Client fd=44 disconnected
Client fd=46 connected readonly=1
Client fd=46 auth sasl allow test
Client fd=46 disconnected
The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.
* Makefile.am: Add examples/systemtap subdir
* autobuild.sh: Disable dtrace for mingw32
* configure.ac: Add check for dtrace
* daemon/.gitignore: Ignore generated dtrace probe file
* daemon/Makefile.am: Build dtrace probe header & object
files
* daemon/libvirtd.stp: SystemTAP convenience probeset
* daemon/libvirtd.c: Add connect/disconnect & TLS probes
* daemon/remote.c: Add SASL and PolicyKit auth probes
* daemon/probes.d: Master probe definition
* daemon/libvirtd.h: Add convenience macro for probes
so that compilation is a no-op when dtrace is not available
* examples/systemtap/Makefile.am, examples/systemtap/client.stp
Example systemtap script using dtrace probe markers
* libvirt.spec.in: Enable dtrace on F13/RHEL6
* mingw32-libvirt.spec.in: Force disable dtrace
Add a test suite for check parsing, formatting, range calculation
and netmask checking APIs in virSocketAddr.
* tests/sockettest.c, tests/Makefile.am: Add new test case
All the inet_* functions can be replaced with calls to the
virSocket APIs. Since many of the inet_* funtions are unsafe,
and the remainder are obsolete, forbid all future use of them
in libvirt.
* Makefile.nonreentrant: Ban use of inet_*
The inet_pton and inet_ntop functions are obsolete, replaced
by getaddrinfo+getnameinfo with the AI_NUMERICHOST flag set.
These can be accessed via the virSocket APIs.
The bridge.c code had methods for fetching the IP address of
a bridge which used inet_ntop. Aside from the use of inet_ntop
these methods are broken, because a NIC can have multiple
addresses and this only returns one address. Since the methods
are never used, just remove them.
* src/conf/network_conf.c, src/nwfilter/nwfilter_learnipaddr.c:
Replace inet_pton and inet_ntop with virSocket APIs
* src/util/bridge.c, src/util/bridge.h: Remove unused methods
which called inet_ntop.
The addrToString functionality is now available via the
virSocketFormatAddrFull method.
* daemon/remote.c, src/remote/remote_driver.c: Remove
addrToString methods
The virSocketParse method was not doing any error reporting
which meant the true cause of the problem was lost. Remove
all error reporting from callers, and push it into virSocketParse
* src/util/network.c: Add error reporting to virSocketParse
* src/conf/domain_conf.c, src/conf/network_conf.c,
src/network/bridge_driver.c: Remove error reporting in
callers of virSocketParse
The getnameinfo() function is more flexible than inet_ntop()
avoiding the need to if/else the code based on socket family.
Also make it support UNIX socket addrs and allow inclusion
of a port (service) address. Finally do proper error reporting
via normal APIs.
* src/conf/domain_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c,
src/qemu/qemu_conf.c: Fix error handling with virSocketFormat
* src/util/network.c: Rewrite virSocketFormat to use getnameinfo
and cope with UNIX socket addrs.
The nwIPAddress was simply a wrapper about virSocketAddr.
Just use the latter directly, removing all the extra field
de-references from code & helper APIs for parsing/formatting.
Also remove all the redundant casts from strong types to
void * and then immediately back to strong types.
* src/conf/nwfilter_conf.h: Remove nwIPAddress
* src/conf/nwfilter_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c:
Update to use virSocketAddr and remove void * casts.
There was a typo in the IPv6 path of virSocketCheckNetmask which
caused it to never execute.
* src/util/network.c: s/AF_INET/AF_INET6/ in virSocketCheckNetmask
The virSocketParseAddr function was accepting any AF_* constant
and using that to set the ai_flags field in struct addrinfo.
This is invalid, since address families must go in the ai_family
field of the struct.
* src/util/network.c: Fix handling of address family
* src/conf/network_conf.c, src/network/bridge_driver.c: Pass
AF_UNSPEC instead of relying on it being 0.
Some operations on socket addresses need to know the length of
the sockaddr struct for the particular address family. This
info was being discarded when passing around virSocketAddr
instances. Turn it from a union into a struct containing
union+socklen_t fields, so length is always kept around.
* src/util/network.h: Add socklen_t field to virSocketAddr
* src/util/network.c, src/network/bridge_driver.c,
src/conf/domain_conf.c: Update to take account of new
struct definition.
If getnameinfo() with NI_NUMERICHOST set fails, there are no
grounds to expect inet_ntop to succeed, since these calls
are functionally equivalent. Remove useless inet_ntop code
in the getnameinfo() error path.
* daemon/remote.c, src/remote/remote_driver.c: Remove
calls to inet_ntop
* src/libvirt_private.syms: Sort by header name, then within
header, and drop duplicate virNetworkDefParseNode,
virFileLinkPointsTo and virXPathBoolean.
The QEMU 0.13 release is finally out and from testing in RHEL-6
we know that its JSON and netdev features are now good enough
for us to use by default.
* src/qemu/qemu_conf.c: Enable JSON + netdev for QEMU >= 0.13
There is no point in trying to fill params beyond the first error,
because when qemuDomainGetMemoryParameters returns -1 then the caller
cannot detect which values in params are valid.
