1 | Version 1.39 | ||
2 | ------------ | ||
3 | Defer close of a file handle slightly if pending writes depend on that file handle | ||
4 | (this reduces the EBADF bad file handle errors that can be logged under heavy | ||
5 | stress on writes). | ||
6 | |||
7 | Version 1.38 | ||
8 | ------------ | ||
9 | Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket) | ||
10 | to be smaller at first (but increasing) so large write performance performance | ||
11 | over GigE is better. Do not hang thread on illegal byte range lock response | ||
12 | from Windows (Windows can send an RFC1001 size which does not match smb size) by | ||
13 | allowing an SMBs TCP length to be up to a few bytes longer than it should be. | ||
14 | wsize and rsize can now be larger than negotiated buffer size if server | ||
15 | supports large readx/writex, even when directio mount flag not specified. | ||
16 | Write size will in many cases now be 16K instead of 4K which greatly helps | ||
17 | file copy performance on lightly loaded networks. Fix oops in dnotify | ||
18 | when experimental config flag enabled. Make cifsFYI more granular. | ||
19 | |||
20 | Version 1.37 | ||
21 | ------------ | ||
22 | Fix readdir caching when unlink removes file in current search buffer, | ||
23 | and this is followed by a rewind search to just before the deleted entry. | ||
24 | Do not attempt to set ctime unless atime and/or mtime change requested | ||
25 | (most servers throw it away anyway). Fix length check of received smbs | ||
26 | to be more accurate. Fix big endian problem with mapchars mount option, | ||
27 | and with a field returned by statfs. | ||
28 | |||
29 | Version 1.36 | ||
30 | ------------ | ||
31 | Add support for mounting to older pre-CIFS servers such as Windows9x and ME. | ||
32 | For these older servers, add option for passing netbios name of server in | ||
33 | on mount (servernetbiosname). Add suspend support for power management, to | ||
34 | avoid cifsd thread preventing software suspend from working. | ||
35 | Add mount option for disabling the default behavior of sending byte range lock | ||
36 | requests to the server (necessary for certain applications which break with | ||
37 | mandatory lock behavior such as Evolution), and also mount option for | ||
38 | requesting case insensitive matching for path based requests (requesting | ||
39 | case sensitive is the default). | ||
