Address some credit2 issues. This patch series, along with the recent changes to the cpupools interface, should address some of the strange credit2 instability. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Currently we use non-cryptographically secure random numbers in two places, the error filter (to inject errors at random) and the random plugin. For this we have used either random_r or a home-brew-ish Linear Congruential Generator. Use of random_r is problematic on BSDs because it doesn't exist there. Use of the LCG is simply a bad choice. Replace both uses with a better quality and

Hi Arjen, in server/upsd.c r731, you moved the call conf_load() from after check_perms() (~ l.1020) to before setupsignals() (~ l.989). The problem is that conf_load() needs to open the ups driver socket, and it assumes that STATEPATH is the current working directory. The directory is only set in l.1016. Therefore, the first attempt to open a socket will always fail. From the user's point of

Hello, This small series deals with some weirdness in the mechanism with which the credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are available in the changelog of the first patch. The new approach has been extensively benchmarked and proved itself either beneficial or harmless. That means it does not introduce any significant amount of overhead and/or performances

Annotate some function parameters with attribute((nonnull)). Only do this for internal headers where we are sure that we will be using sufficiently recent GCC or Clang. For the public header files (ie. include/nbdkit-*.h) it may be that people building out of tree plugins are using old GCC which had problems, or even other compilers that don't support this extension at all. Libvirt has an

v2: - Fix seeding. - Add a test that nbdkit-random-plugin is producing something which looks at least somewhat random. Rich.

Should we use attribute((nonnull)) at all? There's a very interesting history of this in libvirt -- try looking at commit eefb881 plus the commits referencing eefb881 -- but it does seem to work for me using recent GCC and Clang. I only did a few functions because annotating them gets old quickly... Rich.

Hello everyone, this is the very first version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See

in _csched_cpu_pick(), as not doing so may result in the domain''s node-affinity mask (as retrieved by csched_balance_cpumask() ) and online mask (as retrieved by cpupool_scheduler_cpumask() ) having an empty intersection. Therefore, when attempting a node-affinity load balancing step and running this: ... /* Pick an online CPU from the proper affinity mask */

v1 was here: https://www.redhat.com/archives/libguestfs/2019-January/msg00008.html In v2 I have provided two patches: The first patch extends attribute((nonnull)) to most internal functions, but not to the external API. The second patch uses a macro so that attribute((format)) is only used in the public API on GCC or Clang. At least in theory these headers could be used by a C compiler which

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen.

The following series flushes my documentation queue and replaces previous postings of those patches. The main difference is that the xl cfg file is now formatted using POD instead of markdown and presented as a manpage. I have setup a cron job to build docs/html and publish it at http://xenbits.xen.org/docs/unstable/ (it''s a bit bare right now). The motivation for some of these patches

(Second try to send this. I wonder if the first one gotten eaten by a spam filter; I'll link to patches instead of attaching them.) Here are the tincctl patches I've been working on. They apply to http://www.tinc-vpn.org/svn/tinc/branches/1.1@1545. I intend to commit them once the crypto stuff's fixed. Since they're basically done, I'm emailing them now for review and in case

Hi. To begin with, I have a freshly built RedHat Linux 8.0 box running samba 2.2.8a. The kernel version is 2.4.18-14. I downloaded and compiled samba from source. I am using LPRng-3.8.9-6 as my printing system. The attached printer is a Lexmark Z22 printer and it is attached to the parralel port. Problem: For the life of me, I can't get NT type clients, NT4, 2K and XP to print to samba.
