[PATCH] Don't allow a backslash in a path component (CVE-2006-1863)

2006-04-24T20:06:59+00:00

Unless Posix paths have been negotiated, the backslash, "\", is not a valid
character in a path component.

[PATCH] Incorrect signature sent on SMB Read

2006-04-17T20:16:06+00:00

Fixes Samba bug 3621 and kernel.org bug 6147

For servers which require SMB/CIFS packet signing, we were sending the
wrong signature (all zeros) on SMB Read request.  The new cifs routine
to do signatures across an iovec was not complete - and SMB Read, unlike
the new SMBWrite2, did not fall back to the older routine (ie use
SendReceive vs. the more efficient SendReceive2 ie used the older
cifs_sign_smb vs. the disabled  cifs_sign_smb2) for calculating signatures.

This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers
of SendReceive2 can get SMB/CIFS packet signatures.

Now that cifs_sign_smb2 is supported, we could start using it in
the write path but this smaller fix does not include the change
to use SMBWrite2 when signatures are required (which when enabled
will make more Writes more efficient and alloc less memory).
Currently Write2 is only used when signatures are not
required at the moment but after more testing we will enable
that as well).

Thanks to James Slepicka and Sam Flory for initial investigation.

[CIFS] Always match oplock break (cache notification) to the right tcp

2006-03-05T03:39:55+00:00

session when multiply mounted.

Fixes slow response when cifs client is mounted to shares on multiple
servers and oplock break occurs (usually due to attempt to multiply open a
file).  When treeids on mutiple mounted shares match and we find the wrong
match first, we searched for the wrong cached files to send oplock break
response for which usually meant that no matching file was found and thus
the server would have to timeout the notification.  Oplock break timeout is
about 20 seconds on some servers so this could cause significantly slower
performance on file open calls in a few cases (in particular when multiple
shares are mounted from multiple servers, tree ids match, and we have a
cached file which is later opened multiple times).  This was the most
important of the bugs that was found and fixed at Connectathon
(interoperability testing event) this week.

Thanks to Adrian Bunk for debugging the problem and to Shaggy for
helping find the solution.

Also added a fix for 64K pages we found in loosely-related testing

[CIFS] Make cifs default wsize match what we actually want to send (52K

2006-01-25T04:26:48+00:00

typically - header + 13 pages).

Forgetting to set wsize on the mount command costs more than 10% on large
write (can be much more) so this makes a saner default.  We still shrink
this default smaller if server can not support it.
