Subject: [Bug 15196] New: O_APPEND not translated to FILE_APPEND_DATA open flag
Date: Sun, 09 Oct 2022 01:20:23 +0000 [thread overview]
Message-ID: <bug-15196-10630@https.bugzilla.samba.org/> (raw)
https://bugzilla.samba.org/show_bug.cgi?id=15196
Bug ID: 15196
Summary: O_APPEND not translated to FILE_APPEND_DATA open flag
Product: CifsVFS
Version: 5.x
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P5
Component: kernel fs
Assignee: sfrench@samba.org
Reporter: bjacke@samba.org
QA Contact: cifs-qa@samba.org
Target Milestone: ---
While testing the "append data" ACL permission, I wantted to try this out with
cifs vfs against a Windows 10 machine as server.
"tee -a" is using O_APPEND but it looks like cifs vfs is not translating
O_APPEND open calls to SMB's FILE_APPEND_DATA. So files that have "append only"
permission but not "write data" permission will not be "append writable" by
cifs vfs in cases where they shold.
