[PATCH 6.7 181/432] cifs: open_cached_dir(): add FILE_READ_EA to desired access

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eugene Korenevsky <ekorenevsky@xxxxxxxxxxxxx>

[ Upstream commit f1b8224b4e6ed59e7e6f5c548673c67410098d8d ]

Since smb2_query_eas() reads EA and uses cached directory,
open_cached_dir() should request FILE_READ_EA access.

Otherwise listxattr() and getxattr() will fail with EACCES
(0xc0000022 STATUS_ACCESS_DENIED SMB status).
