* linux: Force build failure if modules build failsKeir Fraser2007-12-201-1/+1
| | | | | | | | | | | When building a linux kernel, if the modules build fails, then the build carries on regardless. The problem is simple - the "make modules" failure is not seen by the calling make since its return value is not what is returned. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
* hvm: Fix TPMD and QEMU connectionKeir Fraser2007-12-201-0/+5
| | | | | | | | | | | | In HVM domain, MA_Transmit function in tcgbios sometimes become an error (TCG_NO_RESPONSE). The cause of the error is not to make connection of QEMU and TPMD instance within a timeout of MA_Transmit function. Before the MA_Transmit function was called, the attached patch corrected so that connection of QEMU and TPMD might be completed. Signed-off-by: Kouichi YASAKI <yasaki.kouichi@jp.fujitsu.com>

* tools/examples/block better use of losetup -rKeir Fraser2007-12-191-3/+6
| | | | | | | | | | | | Use losetup -r when the vbd is specified to be readonly, but only if -r is supported (rather than always creating a writeable losetup mapping if possible). This was inspired by (but not derived from) a diff from the Fedora 8 patchset which uses -r iff the vbd is specified as readonly. We need to be cleverer upstream because not all systems have losetup -r. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* Fix master/slave handling in xenconsoled and qemuKeir Fraser2007-12-192-66/+141
| | | | | | | | | | | | | | | Fix a number of problems with the pty handling: - make openpty() implementation work on Solaris - set raw on the slave fd, not the master, as the master doesn't have a line discipline pushed on Solaris - make sure we don't leak the slave fd returned from openpty() - don't use the 'name' argument of openpty() as it's a security risk - note behaviour of a zero read of the master on Solaris - remove pointless tcget/setattr Signed-off-by: John Levon <john.levon@sun.com> Signed-off-by: Samuel Thibault <samuel.thibault@citrix.com>

* [IA64] xenoprof: various fix on linux-xen/perfmon.cAlex Williamson2007-12-171-13/+98
| | | | | | | | | | | | | | | | Various fixes on xen/arch/ia64/linux-xen/perfmon.c - Fix starting/stopping sampling. So far IPI is used. but psr.pp isn't preserved when nested interrupt case with VTi domain. Instead timer is used. - Redefines ia64_set_pmc() to enable sampling of all xen VMM/guest kernel/guest user process. It supports only generic pmc/pmd. - Twist xenpfm_write_pmcs() It is also used when turning on pmcs. So bailing out when error is not appropriate. Even when error occures, it should continue to update next cpu's pmcs. - Add gdprintk(XENLOG_DEUBG) and BUG_ON()s. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>

* xend: Prevent XenD touching externally managed bridgesKeir Fraser2007-12-151-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With current XenD 3.0.4 or later try the following: brctl addbr demo ifconfig demo up /etc/init.d/xend start /etc/init.d/xend stop ifconfig demo down brctl delbr demo Now, start XenD again.... /etc/init.d/xend start And watch in horror as it re-creates your 'demo' bridge. The problem is that the 'XendNetwork' class does not distinguish between bridge devices that it is managing (ie those created via XenAPI) and those which it does not manage (ie those created by OS distro init scripts, or by apps like libvirt). While initially I thought I could just make XenD ignore externally-managed bridges completely, it seems to needs to know about them otherwise it can't hook up guest VIFs to them correctly. So the attached patch adds a 'managed' flag to the XendNetwork class. Externally managed bridges have this set to False. At startup XenD will now only re-create bridge devices which have the 'managed' flag set to 'True' - ie those created via XenAPI. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

* [IA64] Fix vulnerability of copy_to_user in PAL emulationAlex Williamson2007-12-141-12/+61
| | | | | | | | | | | | | | | | | | | | | | There is a security vulnerability in PAL emulation since alt-dtlb miss handler of HVM absolutely inserts a identity-mapped TLB when psr.vm=0. HVM guest can access an arbitrary machine physical memory with this security hole. Actually windows 2008 destroys the content of machine physical address 0x108000. I think this patch is enough for normal usage. Please see SDM Vol2 11.10.2.1.3 "Making PAL Procedure Calls in Physical or Virtual Mode". If the caller has a responsibility of providing DTR or DTC mapping, xencomm for PAL might be unnecessary. I confirmed there is no problem in linux, windows 2003, windows 2008 with this patch. As for PV domain, the same logic can't be used due to only one vTLB. This patch only checks that the buffer never points VMM address, that would avoid the vulnerability.

| * xenoprof: flush remaining smples when sampling is stopped.Keir Fraser2007-12-141-0/+17
| | | | | | | | | | | | | | | | | | | | Xenoprof notifies guest kernel via VIRQ_XENOPROF when sampled. But it does coarsly based on heuristic so that sometimes VIRQ_XENOPROF isn't delivered resulting in that oprofile daemon collects no sample. To avoid that situation, always send VIRQ_XENOPROF when sampling is stopped. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>

I trust no-one is using path lengths >2kby. This is good because currently a domain client can create a 4kby relative path that the dom0 tools cannot access since they'd have to specify the somewhat longer absolute path. * Removes uses of the host's PATH_MAX (!)
