* Fix xenmon.py to work on SolarisKeir Fraser2007-12-041-5/+20
| | | | | | | | | The xenmon.py script does not work on Solaris because of (1) its assumption that xenbaked is in the users path and, (2) the use of the killall command. Changed xenmon.py to use pkill instead and provided the path to xenbaked on Solaris. Signed-off-by: Tariq Magdon-Ismail <tariqmi@sun.com>

* xenmon: Fix security vulnerability CVE-2007-3919.Keir Fraser2007-10-232-2/+2
| | | | | | | | | | | | | | | The xenbaked daemon and xenmon utility communicate via a mmap'ed shared file. Since this file is located in /tmp, unprivileged users can cause arbitrary files to be truncated by creating a symlink from the well-known /tmp filename to e.g., /etc/passwd. The fix is to place the shared file in a directory to which only root should have access (in this case /var/run/). This bug was reported, and the fix suggested, by Steve Kemp <skx@debian.org>. Thanks! Signed-off-by: Keir Fraser <keir@xensource.com>

* [XENMON] Add argument check of "--ms_per_sample" option.kfraser@localhost.localdomain2006-09-191-0/+5
| | | | | | | | | | | | | | | | If a value of "--ms_per_sample" option is larger than a value of "--time" option, xenmon may generate no log file. So, too large "--ms_per_sample" should be treated as an error. e.g. % xenmon.py --ms_per_sample=2000 -t 1 -n usage: xenmon.py [options] xenmon.py: error: option --ms_per_sample: too large (> 1000 ms) # Notice that a unit of "--time" is a second.

* Replace dom0_ops hypercall with three new hypercalls:kfraser@localhost.localdomain2006-08-251-18/+17
| | | | | | | | | | | | | | | | | | | | | | 1. platform_op -- used by dom0 kernel to perform actions on the hardware platform (e.g., MTRR access, microcode update, platform quirks, ...) 2. domctl -- used by management tools to control a specified domain 3. sysctl -- used by management tools for system-wide actions Benefits include more sensible factoring of actions to hypercalls. Also allows tool compatibility to be tracked separately from the dom0 kernel. The assumption is that it will be easier to replace libxenctrl, libxenguest and Xen as a matched set if the dom0 kernel does not need to be replaced too (e.g., because that would require vendor revalidation). From here on we hope to maintain dom0 kernel compatibility. This promise is not extended to tool compatibility beyond the existing guarantee that compatibility will not be broken within a three-level stable release [3.0.2, 3.0.3, etc.].

* Domain ID/index mapping in xenmon.kfraser@localhost.localdomain2006-07-102-122/+197
| | | | | | | | | | | | | | | This patch addresses the problem of xenbaked/xenmon not dealing with large domain ID's. Xen Domain ID's increase monotonically as domains are created; The ID's are not (often) recycled. Xenbaked was using the domain ID's as indices to arrays of data, and this scheme blows up as soon as a domain ID exceeds the array size. Code has been changed in xenbaked and xenmon to isolate domain id's from array indices, so everything is indirect. Users should not notice any difference in behavior.

* This is a patch for XenMon which only applies to the userspace tools. kaf24@firebug.cl.cam.ac.uk2006-04-144-92/+284
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The primary purpose of this patch is to add support for non-polling access to the xen trace buffers. The hypervisor changes have already been accepted. Also included are a few bug fixes and some minor new features: 1. If xenmon is run without first allocating trace buffers (via 'setsize') and enabling them (via 'tbctl'), then this is done automatically using sensible defaults. 2. There was a bug that caused the first second's worth of data output from xenmon to be erroneous; This has been fixed. 3. There was a bug that caused xenmon to sometimes not display data for newly created domains; This has also been fixed. 4. The xenmon display has a 'heartbeat' which flickers once per second. This is to show that xenmon is still alive, even though the display isn't changing at all, a situation that can happen sometimes when there is nothing at all happening on a particular cpu. 5. Added cpu utilization display to the top of the xenmon window. 6. Added a bunch of options in xenmon to control exactly which metrics are displayed, so the screen doesn't get cluttered with stuff you're not interested in. The new options are: --allocated --noallocated --blocked --noblocked --waited --nowaited --excount --noexcount --iocount --noiocount 7. Added an option ("--cpu=N") to xenmon to specify which physical cpu you'd like data displayed for. 8. Updated the README with information about default trace buffer size, etc. Signed-off-by: Rob Gardner <rob.gardner@hp.com>
