[libvirt] [PATCH] Workaround for broken GCC in Debian Etch
by Maximilian Wilhelm 05 Aug '09

05 Aug '09

Hi again! I missed one patch for working around a GCC bug in Debian Etch regarding limit definitions. Sorry for the unstripped git-format-patch outputs, I just realised this after pressing send :( (This seems to be not my day :)) Ciao Max -- Gib Dein Bestes. Dann übertriff Dich selbst!

[libvirt] [PATCH] Add some automatic dependency checks for configure to enable/disable {ESX, UML, LXC, Xen-Inotify}
by Maximilian Wilhelm 05 Aug '09

05 Aug '09

Hi! While building libVirt on an older Debian Etch machine, I stumbled across some automatic enabled drivers which stopped configure and make very badly due to missing header files, old libraries and stuff. So I decided to improve the automagic tests so others won't face the same problem again :) Find four patches attached. Ciao Max -- Fortschritt bedeutet, einen Schritt so zu machen, daß man den nächsten auch noch machen kann.

The attached second GSX patch adds a gsx:// scheme to the ESX driver, so you can connect to a GSX host using virsh -c gsx://host and the driver will select the port automatically dependent on the scheme and transport. Here gsx scheme and default transport https result in port 8333. Matthias

[libvirt] PATCH: Fix escaping for 8-bit high characters
by Daniel P. Berrange 04 Aug '09

04 Aug '09

The virBufferEscapeString method has a broken test *cur > 0x20 which causes all 8-bit high characters to be lost as 'cur' is a signed char. This obviously dooms anyone using UTF-8 characters outside the boring old ASCII-7 range, like this guy https://bugzilla.redhat.com/show_bug.cgi?id=479517 Daniel diff --git a/src/buf.c b/src/buf.c index 259175d..c802aa2 100644 --- a/src/buf.c +++ b/src/buf.c @@ -304,7 +304,7 @@ virBufferEscapeString(const virBufferPtr buf, const char *format, const char *st *out++ = 'o'; *out++ = 's'; *out++ = ';'; - } else if ((*cur >= 0x20) || (*cur == '\n') || (*cur == '\t') || + } else if (((unsigned char)*cur >= 0x20) || (*cur == '\n') || (*cur == '\t') || (*cur == '\r')) { /* * default case, just copy ! -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] [PATCH] Use virGetHostname instead of gethostname.
by Chris Lalancette 02 Aug '09

02 Aug '09

Fix up qemudDomainMigratePrepare2 to use virGetHostname instead of gethostname. Besides the fact that virGetHostname is far more clever, there was a latent bug in the handling that could cause a buffer overflow on a very long hostname.
