I've a server where clients can connect to using direct-streamlocal at openssh.com. I want that the server "knows" the address of the client. I've tried using the peercredentials of the process connecting my server (which is a sshd process) and check the environment. I thought that in the environment the var SSH_CLIENT would be set, but that did not work. This sshd process has

...g away with a lot less complexity because I dont need to watch for changes in files. Because thats not something I'm indexing. If I'd be adding more metadata (even only size!) I have to verify that it stays correct and start to listen to "file X has changed" events somehow... fanotify seems like a sweet framework for that, but sadly ZFS is incompatible with it... Samba does not let me get this data efficiently either, so Im forced to regular scans of the whole fs.... which might take a while depending on the amount of files. Adding support for opensearch though shouldnt be...

...tory an inotify watch must be created, taking about 1KB of kernel memory per watch. If you got a million directories this is a GB of unswapable memory use. Unfortunally the Linux kernel doesn't provide a better way yet, and I suppose other tools like sysdig suffer from the same issue. There is fanotify, but that doesn't report move event and thus is not useable for this task.

Hi, we have a huge directory tree. * 17M files (number of files) * 2.2TBytes of data. * Only 0.1% changes per day Current pain: rsyncs directory tree traversal needs to long to discover the changed files. Only few files change. I discovered the tool sysdig which could be used to monitor the files which were changed. Then we could feed the list of changed files to rsync and avoid the

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the

The main motivation for this patch is to enable cloud service providers to provide an accelerated datapath to virtio-net enabled VMs in a transparent manner with no/minimal guest userspace changes. This also enables hypervisor controlled live migration to be supported with VMs that have direct attached SR-IOV VF devices. Patch 1 introduces a failover module that provides a generic interface for
