Hi Brian Thanks for the response. It is a WSL2 environment with kernel version: 5.15.153. We have used a kernel version 6.6.36.3 as well. Scenario fails there as well. root@DESKTOP-OOHD5UG:/sys/kernel/debug/tracing# uname -a Linux DESKTOP-OOHD5UG 5.15.153.1-microsoft-standard-WSL2 #1 SMP Fri Mar 29 23:14:13 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux Mount point information: C:\ on /mnt/c type 9p (rw,noatime,dirsync,aname=drvfs;path=C:\;uid=1000;gid=1000;symlinkroot=/mnt/,mmap,access=client,msize=65536,trans=fd,rfd=5,wfd=5) We aren't using any sort of file syncing service. We have installed a defender software which is marking mount points for FANOTIFY to intercept filesystem events. On removing the marking, git clone succeeds.

Any help in this regard would be highly appreciated. Can you tell us more about what environment you're using? Is this Windows, macOS, Linux, WSL (1 or 2), or something else? What version of the OS is it? What is backing the 9p file system (and what file system type is it), and how are you mounting it? Is it a network file system? Are you using any sort of non-default antivirus, firewall, or monitoring software, and if so, have you tried to completely uninstall it and restart to see if that fixes the problem? Also, are you using any sort of file syncing service for the directory in question, such as Dropbox or OneDrive? Those are known to corrupt repositories and the Git FAQ is clear that you must not store repositories within them. The reason I ask all these questions is because I have an open source tool which allows mounting 9p file systems from a remote system by using the Linux kernel's 9p support and I don't see this problem. I don't think there's anything intrinsically problematic with 9p file systems, although you definitely need 9p2000.u or 9p2000.L (the Unix or Linux variants of the protocol) to make the file system suitably functional and POSIX compliant. My guess is that there's something else about your environment that's causing the problem. It looks like maybe you're using some variant of WSL, and maybe you have an antivirus that's preventing the files from being read, which is causing this error on the Linux side. However, without more information, it's not really possible for me to say more about what might be going wrong. -- brian m. carlson (they/them or he/him) Toronto, Ontario, CA
