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@xxxxxxxxx Reporter: bjacke@xxxxxxxxx QA Contact: cifs-qa@xxxxxxxxx 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. -- You are receiving this mail because: You are the QA Contact for the bug.
