* libxc: convert evtchn interfaces to use an opaque handle typeIan Campbell2010-12-231-5/+5
| | | | | | | | | | | | This makes the interface consistent with the changes made to the main interface in 21483:779c0ef9682c. Also fix some references to "struct xc_interface" which should have been simply "xc_interface" in tools/xenpaging, and update QEMU_TAG to pull in the corresponding qemu change.

* trace: share t_info pages only in read-only modeKeir Fraser2010-06-291-5/+5

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-9/+10
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* xentrace: make xentrace and xenmon work on Solaris and *BSD.Keir Fraser2007-11-161-86/+91
| | | | | | | | | | | | - Use getopt() to get rid of argp dependency which does not exist on Solaris and *BSD. Done by Tariq Magdon-Ismail. - Minor modifications by me (Christoph) to make it also work on *BSD. - Tested on Linux by me (Christoph). No functional change on Linux. - Tariq ok'd BSD modifications for Solaris - Tariq ok'd submission by me :) Signed-off-by: Tariq Magdon-Ismail <tariqmi@sun.com> Signed-off-by: Christoph Egger <Christoph.Egger@amd.com>
* xenmon: Fix security vulnerability CVE-2007-3919.Keir Fraser2007-10-231-1/+1
| | | | | | | | | | | | | | | 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>

* Domain ID/index mapping in xenmon.kfraser@localhost.localdomain2006-07-101-103/+164
| | | | | | | | | | | | | | | 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.uk2006-04-141-11/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
