[libvirt] [PATCH] build: nuke all .x-sc* files
by Eric Blake 23 Mar '11

23 Mar '11

Not every day you see a patch that nukes 27 files! * .gnulib: Update to latest, for maint.mk improvements * bootstrap: Resync to gnulib. * bootstrap.conf (ACLOCAL): Swap the secondary aclocal include directory, now that bootstrap picks up gnulib/m4 instead of m4. * Makefile.am (syntax_check_exceptions, EXTRA_DIST): No longer worry about nuked files. * cfg.mk (sc_x_sc_dist_check): Delete dead rule. (VC_LIST_ALWAYS_EXCLUDE_REGEX): Add HACKING. (exclude_file_name_regexp--sc_*): Inline and simplify contents... * .x-sc_*: ...from here, then delete the files. --- * .gnulib c2090a8...0baae9c (28): > maint.mk: allow fine-grained syntax-check exclusion via Make variables > ignore-value tests: Avoid warnings. > passfd: Fix link error on Solaris. > passfd: Fix link error on AIX 5.2. > passfd: Work around bug with CMSG_FIRSTHDR on FreeBSD 6.4. > passfd: Fix compilation error on OpenBSD. > passfd test: Fix warnings. > passfd test: Fix warnings. > passfd module, part 4, tweaks. > passfd module, part 4. > Makefile: rely on GNU make; derive syntax-check rule names > passfd module, part 3. > passfd module, part 2, tweaks. > passfd module, part 2. > wcswidth, mbswidth: Avoid integer overflow. > Oops, fix last commit. > futimens, utimensat: Avoid endless recursion on Solaris 10. > maint.mk: relax a regexp to accommodate other formatting styles > maint.mk: suppress a syntax check false positive > wchar: add explicit dependencies, for Tru64 > passfd module, part 1, tweaks. > passfd module, part 1. > regex-quote: New API. > regex-quote: Fix creation of POSIX extended regular expressions. > doc: Improve doc regarding autopoint vs. gnulib. > Update AC_OPENMP macro for Lahey compiler on GNU/Linux. > parse-duration: remove xalloc.h dependency > bootstrap: honor m4_base when running aclocal .gnulib | 2 +-

[libvirt] [PATCH] qemu: add two hook script events "prepare" and "release"

>From 827261dbe2ab8f1cfd8c84df14bb42fd04df2307 Mon Sep 17 00:00:00 2001 From: Thibault VINCENT <thibault.vincent(a)smartjog.com> Date: Mon, 21 Mar 2011 10:18:06 +0100 Subject: [PATCH] qemu: add two hook script events "prepare" and "release" * Fix for bug #618970 * The "prepare" hook is called very early in the VM statup process before device labeling, so that it can allocate ressources not managed by libvirt, such as DRBD, or for instance create missing bridges and vlan interfaces. * To shutdown these devices, the "release" hook is also required at the very end of the VM destruction.

[libvirt] [libvirt-snmp][PATCH v3 0/3] Add SNMP trap/notification support
by Michal Privoznik 23 Mar '11

23 Mar '11

The third version with micro-version number change. Finally, we have a proof-of-concept implementation of SNMP trap. Two new files were first generated using mib2c then edited, so be careful when re-generating them. Destination of traps is defined in snmpd.conf (trap2sink), and to receive them snmptrapd must be configured and up. The idea behind is - create a thread in which we poll for domain events. Once we receive event notification, we just fire up trap sending. Michal Privoznik (3): Add notification-type object to libvirt MIB Create functions to fill in and send notification packets. Add SNMP trap/notification support.

[libvirt] [PATCH] logging: fix off-by-one bug
by Eric Blake 23 Mar '11

23 Mar '11

Valgrind caught that our log wrap-around was going 1 past the end. Regression introduced in commit b16f47a; previously the buffer was static and size+1 bytes, but now it is dynamic and exactly size bytes. * src/util/logging.c (virLogStr): Don't write past end of log. --- An alternative would be to malloc one larger; but since the log is likely to be a page size multiple and large enough to be worth malloc using mmap, going one larger is likely to waste the bulk of a page.

[libvirt] [PATCH] rpm: require radvd when building network support

[libvirt] [PATCH] domain_conf: drop unused ref-count in snapshot object
by Eric Blake 23 Mar '11

23 Mar '11

The ref count was assigned to 1 at creation, then never modified again until it was decremented just before freeing the object. * src/conf/domain_conf.h (_virDomainSnapshotObj): Delete unused field. (virDomainSnapshotObjUnref): Delete unused prototype. * src/libvirt_private.syms: Likewise. * src/conf/domain_conf.c (virDomainSnapshotObjNew) (virDomainSnapshotObjListDataFree): Update users. (virDomainSnapshotObjUnref): Delete. --- I was about to add ATTRIBUTE_RETURN_CHECK to all Unref methods, when I discovered that this method is (currently) worthless. If we ever change things in the future to have multiple threads referring to snapshot objects and need a reference counter, we can use Wen's proposed new base-class object to do that in a saner manner.

[libvirt] [PATCH] util: Fix return value for virJSONValueFromString if it fails
by Osier Yang 23 Mar '11

23 Mar '11

Problem: "parser.head" is not NULL even if it's free'ed by "virJSONValueFree", returning "parser.head" when "virJSONValueFromString" fails will cause unexpected errors (libvirtd will crash sometimes), e.g. In function "qemuMonitorJSONArbitraryCommand": if (!(cmd = virJSONValueFromString(cmd_str))) goto cleanup; if (qemuMonitorJSONCommand(mon, cmd, &reply) < 0) goto cleanup; ...... cleanup: virJSONValueFree(cmd); It will continues to send command to monitor even if "virJSONValueFromString" is failed, and more worse, it trys to free "cmd" again. Crash example: {"error":{"class":"QMPBadInputObject","desc":"Expected 'execute' in QMP input","data":{"expected":"execute"}}} {"error":{"class":"QMPBadInputObject","desc":"Expected 'execute' in QMP input","data":{"expected":"execute"}}} error: server closed connection: error: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Connection refused error: failed to connect to the hypervisor This fix is to: 1) return NULL for failure of "virJSONValueFromString", 2) and it seems "virJSONValueFree" uses incorrect loop index for type of "VIR_JSON_TYPE_OBJECT", fix it together. * src/util/json.c --- src/util/json.c | 7 +++++-- 1 files changed, 5 insertions(+), 2 deletions(-) diff --git a/src/util/json.c b/src/util/json.c index f90594c..be47f64 100644 --- a/src/util/json.c +++ b/src/util/json.c @@ -65,7 +65,7 @@ void virJSONValueFree(virJSONValuePtr value) switch (value->type) { case VIR_JSON_TYPE_OBJECT: - for (i = 0 ; i < value->data.array.nvalues ; i++) { + for (i = 0 ; i < value->data.object.npairs; i++) { VIR_FREE(value->data.object.pairs[i].key); virJSONValueFree(value->data.object.pairs[i].value); } @@ -897,6 +897,7 @@ virJSONValuePtr virJSONValueFromString(const char *jsonstring) yajl_parser_config cfg = { 1, 1 }; yajl_handle hand; virJSONParser parser = { NULL, NULL, 0 }; + virJSONValuePtr ret = NULL; VIR_DEBUG("string=%s", jsonstring); @@ -917,6 +918,8 @@ virJSONValuePtr virJSONValueFromString(const char *jsonstring) goto cleanup; } + ret = parser.head; + cleanup: yajl_free(hand); @@ -930,7 +933,7 @@ cleanup: VIR_DEBUG("result=%p", parser.head); - return parser.head; + return ret; } -- 1.7.4
