The following patches were made over Linus tree. The patches fix 3 issues: 1. If a user performs LIO LUN unmapping before the endpoint has been cleared then we can end up trying to free a bogus tmf struct if the TMF is still exucuting when we do the unmap. 2. If vhost_scsi_setup_vq_cmds fails we can leave the tpg->vhost_scsi pointer set and we can end up trying to access a freed struct. 3. Management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N m...

The following patches were made over Linus tree and also apply over mst tree's vhost branch. The patches fix an issue where management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N minutes depending on the device. The problem is that we use a global mutex to protect the list of tpgs but we hold that mutex during those management operations. So if you

Hi, I have an application that want to install the DotNet FrameWork. the Setup of the FrameWork starts, but then fails with the message, Internet Explorer 5.5 or higher would be required. How can I get over this message without really installing an Internet Explorer? As far as I know, for all Applications that require IE, the renderengine khtml is used instead. Could it be hacked in that

Hello Everyone, I would like to have your thoughts on this. Overview of the problem =================== While implementing support for the DWARFv5 debug_macro section support in LLVM. I came across these holes: - The macros infrastructure in CLANG/LLVM is inherently tied to a particular version(v4 macinfo). For instance, consider this snippet from CLANG:

We use Icecast version 2.4.4 and recently added an intro (preroll) to one of our channels. Although we haven't had any direct complaints, there has been a discussion thread with some of our public radio colleagues getting complaints about users receiving a repeat of the intro many times when their device switches from WiFi to LTE or unstable Internet connections.
