* Simplify 'dma heap' logic.Keir Fraser2008-07-281-5/+3
| | | | | | | | | | | | | | | 1. Only useful for NUMA systems, so turn it off on non-NUMA systems by default. 2. On NUMA systems, by default relate the DMA heap size to NUMA node 0 memory size (so that not all of node 0's memory ends up being 'DMA heap'). 3. Remove the 'dma emergency pool'. It's less useful now that running out of low memory isn;t as fatal as it used to be (e.g., when we needed to be able to allocate low-memory PAE page directories). Based on patches by Andre Przywara and Xiaowei Yang. Signed-off-by: Keir Fraser <keir.fraser@citrix.com>

* tools/docs: Fix example and default IP addresses.Keir Fraser2008-01-172-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In various places in documentation and code, IP addresses are provided as examples, defaults, or dummy configuration. In general the specific IP addresses used in Xen are not always appropriate. (For example, 1.2.3.4 is used in a few places!) The following addresses should be used: * For examples and documentation, 192.0.2.0/24. (See RFC3330.) * For defaults for private networks, a random network from RFC1918. I have randomly selected 172.30.206.0/24 for this purpose and documented this in at the only registry I know of, www.ucam.org/cam-grin. This network should henceforth be used for default configurations of local bridges, test networks, etc. in Xen tools. The following addresses should NOT be used: * 10.0.*.*, 10.1.*.*, 192.168.0.*, 192.168.1.*, etc. Using these addresses gives greatly increased likelihood of collision, as ignorant network administrators and reckless middlebox vendors often pick networks from the bottom of 10/8 and 192.168/16. * 169.254.*.*. These are reserved for zeroconf (ad-hoc networking) and should not be used for Xen private networks, bridges, etc., etc. Use of these addresses by Xen scripts causes trouble on hosts (eg laptops) which find themselves in ad-hoc networking environments. I think this is not hypothetical (!) since at least one Linux distribution have specific code to detect this case and cause Xen startup to fail iff the host already has an external zeroconf address. * 1.2.3.4. WTF !? I have also used 127.0.255.255 in one place where apparently a dummy address is needed (some Linux kernels won't accept a lack of an NFS server address). If 127.0.255.255 is mistakenly used it is unlikely to do any damage to real traffic even if it does escape into the network at large. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* xenstore size limitsKeir Fraser2007-12-141-1/+17
| | | | | | | | | | | | | | | * Documents the existing 4kby size limit on xenstore message payloads * Causes xs.c in libxenstore to fail locally rather than violating said limit (which is good because xenstored kills the client connection if it's exceeded). * Introduces some limits on path lengths in xenstored. 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 (!)

* xend, acm: Extend Xen-API with function to reset the policyKeir Fraser2007-12-121-0/+39
| | | | | | | | | | | | This patch extends the Xen-API and the legacy XML-RPC interface with a function to reset the policy on the system (through an update with the default policy). I adapted the code in 'xm resetpolicy' to use this now. This patch also extends libxen and the documentation to reflect the new function. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>
* xenstore: document the xenstore protocolKeir Fraser2007-12-051-0/+287
| | | | | | | | | | | | | | | | | The attached patch adds a new text file docs/misc/xenstore.txt which describes the actual protocol implemented by xenstored. This was reverse-engineered from the actual code in tools/xenstore. I didn't bother making any automatic arrangements to ensure that the implemented and documented protocols are kept in step (for example, automatic code generation, etc.) The protocol is rather messy unfortunately and unsuitable for an xdr approach, and in any case is not likely to change very quickly. Also in this patch are a couple of comments for xenstored_core.c which help clarify the behaviour of some payload parsing helper functions. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
* [USER GUIDE] [ACM/sHype Update] User Guide Update for sHype/XenKeir Fraser2007-12-053-1111/+3150
| | | | | | | | | | | | This patch updates the ACM/sHype user guide chapter. It updates the examples throughout the chapter and describes advanced security policy and domain management based on the new ACM xm command extensions that were submitted this morning (cf. http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00043.html and http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00041.html).

* Implement legacy XML-RPC interface for ACM commands.Keir Fraser2007-12-051-37/+24
| | | | | | | | | | | | | | | | | | | | | | | | This patch implements a (non Xen-API) legacy XML-RPC interface for the ACM commands and funnels the calls into code introduced by the Xen-API support for ACM security management. Since some of the functionality has changed, also the xm applications have changed. In particular the following old commands have been removed along with some tools the have become obsolete now: - loadpolicy (included in: setpolicy) - makepolicy (included in: setpolicy) - cfgbootpolicy (included in: setpolicy) and the following commands been introduced: - setpolicy - getpolicy - resetpolicy All tools have been adapted to work in Xen-API and legacy XML-RPC mode. Both modes support the same functionality. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>

* [IA64] Don't share privregs with hvm domainAlex Williamson2007-10-221-2/+6
| | | | | | | | | | | | | | | | Don't share privregs with hvm domain and twist IA64 xen dump core format slightly. Xen shares privregs pages with IA64 HVM domain for xm dump-core to dump the pages. However sharing the page allows hvm guest domain peek/destroy the page contents that might cause xen crash. And the xen dump core file doesn't need privregs page because cpu context should be obtained from vcpu context in case of IA64 HVM domain. Although this patch modify xen dump core format, current crash utility (at least crash 4.0-4.7) doesn't look into .xen_ia64_mmapped_regs section and I don't know any other tools to understand xen dump core file. So this format modification doesn't cause incompatibility issue. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
