This can happen when leases have been\ntemporarily or permanently disabled. When this happens, we will have\nopen_cached_dir making an open without lease context and the response\nwill anyway be rejected by open_cached_dir (thereby forcing a close to\ndiscard this open). That's unnecessary two round-trips to the server.\n\nThis change adds a check before making the open request to the server\nto make sure that SMB2_open_init did add the expected lease context\nto the open in open_cached_dir.\n\nCc: <stable@vger.kernel.org>\nSigned-off-by: Shyam Prasad N <sprasad@microsoft.com>\n---\n fs/smb/client/cached_dir.c | 7 +++++++\n 1 file changed, 7 insertions(+)", "diff": "diff --git a/fs/smb/client/cached_dir.c b/fs/smb/client/cached_dir.c\nindex 04bb95091f498..e9917e5204b00 100644\n--- a/fs/smb/client/cached_dir.c\n+++ b/fs/smb/client/cached_dir.c\n@@ -286,6 +286,13 @@ int open_cached_dir(unsigned int xid, struct cifs_tcon *tcon,\n \t\t\t &rqst[0], &oplock, &oparms, utf16_path);\n \tif (rc)\n \t\tgoto oshr_free;\n+\n+\tif (oplock != SMB2_OPLOCK_LEVEL_II) {\n+\t\trc = -EINVAL;\n+\t\tcifs_dbg(FYI, \"unexpected oplock level %d for cached directory\\n\", oplock);\n+\t\tgoto oshr_free;\n+\t}\n+\n \tsmb2_set_next_command(tcon, &rqst[0]);\n \n \tmemset(&qi_iov, 0, sizeof(qi_iov));\n", "prefixes": [ "2/7" ] }
