[libvirt] [PATCH v2] [TCK] nwfilter: Add test cases for ipset
by Stefan Berger 23 May '12

23 May '12

Add test cases for ipset support. Since ipset may not be available on all system, the first line of the XML file containing the test filter has been extended with a specially formatted XML comment containing a command line test for whether the test case can be run at all. The format of that line is:  If the tests in this line don't succeed, the test case is skipped. Also add a test case cleaning up the created ipset. Run this test after all other tests using alphabetical ordering. --- v2: - addressed Eric Blake's comments --- scripts/nwfilter/nwfilter2vmtest.sh | 36 +++++++-- scripts/nwfilter/nwfilterxml2fwallout/ipset-test.fwall | 39 ++++++++++ scripts/nwfilter/nwfilterxml2fwallout/zzz-ipset-cleanup.fwall | 1 scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml | 25 ++++++ scripts/nwfilter/nwfilterxml2xmlin/zzz-ipset-cleanup.xml | 5 + 5 files changed, 99 insertions(+), 7 deletions(-) Index: libvirt-tck/scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml =================================================================== --- /dev/null +++ libvirt-tck/scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml @@ -0,0 +1,25 @@ + +<filter name='tck-testcase' chain='root'> + <uuid>5c6d49af-b071-6127-b4ec-6f8ed4b55335</uuid> + <rule action='accept' direction='out'> + <all ipset='tck_test' ipsetflags='src,dst' /> + </rule> + <rule action='accept' direction='in'> + <all state='NONE' ipset='tck_test' ipsetflags='src,dst' comment='in+NONE'/> + </rule> + <rule action='accept' direction='out'> + <all state='NONE' ipset='tck_test' ipsetflags='src,dst' comment='out+NONE'/> + </rule> + <rule action='accept' direction='in'> + <all ipset='tck_test' ipsetflags='SRC,DST,SRC' /> + </rule> + <rule action='accept' direction='in'> + <all ipset='tck_test' ipsetflags='SRC,dSt,SRC' /> + </rule> + <rule action='accept' direction='in'> + <all ipset='$IPSETNAME' ipsetflags='src,dst' /> + </rule> + <rule action='accept' direction='inout'> + <all ipset='$IPSETNAME' ipsetflags='src,dst' comment='inout'/> + </rule> +</filter> Index: libvirt-tck/scripts/nwfilter/nwfilter2vmtest.sh =================================================================== --- libvirt-tck.orig/scripts/nwfilter/nwfilter2vmtest.sh +++ libvirt-tck/scripts/nwfilter/nwfilter2vmtest.sh @@ -107,6 +107,7 @@ checkExpectedOutput() { ifname="$3" flags="$4" skipregex="$5" + skiptest="$6" regex="s/${ORIG_IFNAME}/${ifname}/g" tmpdir=$(mktmpdir) @@ -147,6 +148,18 @@ checkExpectedOutput() { break fi + if [ -n "${skiptest}" ]; then + # treat all skips as passes + passctr=$(($passctr + 1)) + [ $(($flags & $FLAG_VERBOSE)) -ne 0 ] && \ + echo "SKIP ${xmlfile} : ${cmd}" + [ $(($flags & $FLAG_LIBVIRT_TEST)) -ne 0 ] && \ + test_result $(($passctr + $failctr)) "" 0 + [ $(($flags & $FLAG_TAP_TEST)) -ne 0 ] && \ + tap_pass $(($passctr + $failctr)) "SKIP: ${xmlfile} : ${skiptest}" + break + fi + diff -w ${tmpfile} ${tmpfile2} >/dev/null if [ $?

[libvirt] [PATCH] Revert "rpc: Discard non-blocking calls only when necessary"

This reverts commit b1e374a7ac56927cfe62435179bf0bba1e08b372, which was rather bad since I failed to consider all sides of the issue. Thus, the reverted patch actually breaks more than what it fixes and clients (which may even be libvirtd during p2p migrations) will likely end up with a corrupted dispatch queue. --- I will send proper replacement for the reverted patch later once I'm convinced it's correct (more than I was convinced the original one was correct) :-P src/rpc/virnetclient.c | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) diff --git a/src/rpc/virnetclient.c b/src/rpc/virnetclient.c index 3a60db6..d88288d 100644 --- a/src/rpc/virnetclient.c +++ b/src/rpc/virnetclient.c @@ -1265,13 +1265,6 @@ static void virNetClientIOEventLoopPassTheBuck(virNetClientPtr client, virNetCli } client->haveTheBuck = false; - /* Remove non-blocking calls from the dispatch list since there is no - * call with a thread in the list which could take care of them. - */ - virNetClientCallRemovePredicate(&client->waitDispatch, - virNetClientIOEventLoopRemoveNonBlocking, - thiscall); - VIR_DEBUG("No thread to pass the buck to"); if (client->wantClose) { virNetClientCloseLocked(client); @@ -1315,9 +1308,12 @@ static int virNetClientIOEventLoop(virNetClientPtr client, if (virNetSocketHasCachedData(client->sock) || client->wantClose) timeout = 0; - /* If we are non-blocking, we don't want to sleep in poll() + /* If there are any non-blocking calls in the queue, + * then we don't want to sleep in poll() */ - if (thiscall->nonBlock) + if (virNetClientCallMatchPredicate(client->waitDispatch, + virNetClientIOEventLoopWantNonBlock, + NULL)) timeout = 0; fds[0].events = fds[0].revents = 0; @@ -1422,6 +1418,13 @@ static int virNetClientIOEventLoop(virNetClientPtr client, virNetClientIOEventLoopRemoveDone, thiscall); + /* Iterate through waiting calls and if any are + * non-blocking, remove them from the dispatch list... + */ + virNetClientCallRemovePredicate(&client->waitDispatch, + virNetClientIOEventLoopRemoveNonBlocking, + thiscall); + /* Now see if *we* are done */ if (thiscall->mode == VIR_NET_CLIENT_MODE_COMPLETE) { virNetClientCallRemove(&client->waitDispatch, thiscall); -- 1.7.10.2

[libvirt] JSON license is non-free - how are we affected?
by Eric Blake 23 May '12

23 May '12

The QMP monitor uses JSON as its underlying base. However, when you read the license of JSON [1], you will note that it has a pretty severe limitation ("The Software shall be used for Good, not Evil"). In fact, this limitation is severe enough that the FSF has declared that the JSON license is non-free (even if the limitation is unenforceable), and therefore cannot be combined with GPL code: [1] http://www.json.org/license.html [2] https://www.gnu.org/licenses/license-list.html#JSON How do we reconcile this? Obviously, qemu must remain GPL, because it has files that are licensed GPLv2, and the overall license is the restrictive union of all source licenses. But that implies that we cannot include any source code or libraries provided by json.org, if such code is under the incompatible JSON license. Is the JSON license only applicable to code downloaded from json.org, but not to the actual JSON language specification? If so, does that mean that a clean-room implementation of JSON (the language specification) can be written with different license than JSON (the license), and that such alternate code could then be linked into qemu? Is this already the case? It would be a shame to have to reinvent QMP to use a different language specification if the entire JSON language is deemed poisoned. Thoughts? Do we need to seek legal guidance from FSF, Red Hat, or any other organization on how to proceed? -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
