Don''t cast values when other (type safe) mechanisms are available to achieve the same effect.

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

While working on a database scaling problem using a SAP database test suite we discovered that these enterprise level large shared memory databases are very heavy users of mprotect(), to the extent that the performance overhead in current Xenolinux impacts scaling beyond a few cpus quite badly. A single cpu run under Xen has a nominal impact, but scaling out to 8 cpus results in a performance of

Earlier this month there was a patch posted for switching the network frontend/backend drivers to using grant tables. The patch won''t apply cleanly to the current tree. Is there an updated patch available? Any word on how it works, or when it might be merged into the mainline? --Michael Vrable _______________________________________________ Xen-devel mailing list

Hello every body, I am installing the XEN on Fedora, and get some trouble when I boot XEN first time. During the XenLinux booting, a error was issued "Warning: unable to open an initial console" and then system booting stoped. Does any body has a clue on the problem? wei _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hello, I''m new to Xen and especially to the hypervisor code. I''m working off a 3.0.4.1 base and have the following questions regarding the memory management code for an x86, 32-bit platform (capable of supporting PAE). I''m doing some research into providing grant table hypercall support from a Windows 2003 HVM. I have made all the necessary changes to allow the

I was having trouble restarting xend; oftentimes, after I stopped it, it wouldn''t start again. The problem was that xend was unable to open /dev/xen/evtchn because the device was already open. When xend brought up a network interface, I had it set to call a network script that configured DHCP for the new interface. Since dhcpd doesn''t support reloading its configuration, I

Hi, can someone explain whats the meaning of the two blocksizes in the first header of Vorbis, please? So far I assumed that they meant that 2^b0 and 2^b1 were the only two blocksizes used during the whole encode, but something makes me believe they are not: if b0 and b1 are 0xb8 respectively (that I interpeted as 2^11 = 2048 and 2^8 = 256) I observe 3 different deltas between each couple of

Hey guys, I have the x86-64 domU building code for libxc just about ready. It totally gets through the library and creates the domain. But once it does it reboots the machine (and no output to show what happened via the serial console). What techniques would you guys use find out (excluding excessive printks ....I''m doing that right now) what is going on in xen and tracing back to the

Hi, We have several llvm fuzz targets running on OSS-Fuzz, a continuous automated fuzzing service: https://github.com/google/oss-fuzz https://www.usenix.org/sites/default/files/conference/protected-files/usenixsecurity17_slides_serebryany.pdf It has reported a few bugs in cxa_demangler, clang, and dwarfdump already, and we expect to add more fuzz targets to it soon (llvm-isel-fuzzer,

I have a generic function test.equal <- function(obj1, obj2, ...) UseMethod("test.equal") however, the only argument that specific methods use is "fuzz" so I would like to change this to test.equal <- function(obj1, obj2, fuzz=???) UseMethod("test.equal") The problem is that some methods use slightly different default values for fuzz than others. How should

I am working of using libfuzzer and asan to test out a third-party library. As demonstrated in the tutorial, I wrote a fuzz target to fuzz a specific function in the library. The fuzz target is then linked to the library and compiles clean and I do see some tests generated by the fuzzer. However, I have some questions regarding the "right" way to go about doing this. I have doubts that

Hai, Does anybody have problems with a wrong Connected Line ID with asterisk version 1.6 The following bug was for version 1.4, but I cannot make up if this bug is still in version 1.6 http://forums.digium.com/viewtopic.php?t=7780 In version 1.8 it is possible to change the Connected Line ID, but this isn't the case in version 1.6 Regards, Arjan Kroon Mobillion BV
