- Set FD_CLOEXEC on sockets created by curl [#12439](https://github.com/NixOS/nix/pull/12439)
Curl creates sockets without setting FD_CLOEXEC/SOCK_CLOEXEC, this can cause connections to remain open forever when using commands like `nix shell`
This change sets the FD_CLOEXEC flag using a CURLOPT_SOCKOPTFUNCTION callback.
- Git LFS support [#10153](https://github.com/NixOS/nix/pull/10153) [#12468](https://github.com/NixOS/nix/pull/12468)
The Git fetcher now supports Large File Storage (LFS). This can be enabled by passing the attribute `lfs = true` to the fetcher, e.g.
```console
nix flake prefetch 'git+ssh://git@github.com/Apress/repo-with-large-file-storage.git?lfs=1'
```
A flake can also declare that it requires lfs to be enabled:
```
{
inputs.self.lfs = true;
}
```

- Set `FD_CLOEXEC` on sockets created by curl [#12439](https://github.com/NixOS/nix/pull/12439)
Curl created sockets without setting `FD_CLOEXEC`/`SOCK_CLOEXEC`. This could previously cause connections to remain open forever when using commands like `nix shell`. This change sets the `FD_CLOEXEC` flag using a `CURLOPT_SOCKOPTFUNCTION` callback.
