Bug ID: 2579
Summary: Link count support
Product: Portable OpenSSH
Version: 7.2p1
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5
Component: sftp-server

Patch
This patch adds client and server support for transmitting the st_nlink
field
across SSH2_FXP_NAME and SSH2_FXP_ATTRS responses.
One downside is that it adds this much new overhead for those
responses:
sizeof(uint32_t) + sizeof(uint32_t) +
strlen("attr-link-count at openssh.com") + sizeof(uint32_t) +
sizeof(uint64_t)
i.e. 47 bytes.
If this overhead is not acceptable, perhaps this extension can only be
enabled if the client sends the "attr-link-count at openssh.com" extension
in the SSH2_FXP_INIT request. If this is the case, should sftp-client
advertise this extension by default or no?
