[libvirt] [PATCH] Add some automatic dependency checks for configure to enable/disable {ESX, UML, LXC, Xen-Inotify}

by Maximilian Wilhelm

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

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

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.
