Subject: Query Directory level 0x51: FileIdAllExtdBothDirectoryInformation not supported
Date: Mon, 11 May 2026 18:53:02 -0500 [thread overview]
Message-ID: <CAH2r5msyqZYmWxVvdR9sBhDO+ea9uL7nqwGeYtM1GU_vAy-GoA@mail.gmail.com> (raw)
I noticed that Windows clients now start Query Directory requests
using level 0x51, FileIdAllExtdBothDirectoryInformation, and when that
fails (as it does to Samba and ksmbd) it falls back to level 0x25,
FileIdBothDirectoryInformation.
Presumably would help perf if Samba and ksmbd implemented
FileIdAllExtdBothDirectoryInformation Any work started on
implementing that?
