2007-05-05[CIFS] Make sec=none force an anonymous mountJeff Layton
We had a customer report that attempting to make CIFS mount with a null username (i.e. doing an anonymous mount) doesn't work. Looking through the code, it looks like CIFS expects a NULL username from userspace in order to trigger an anonymous mount. The mount.cifs code doesn't seem to ever pass a null username to the kernel, however. It looks also like the kernel can take a sec=none option, but it only seems to look at it if the username is already NULL. This seems redundant and effectively makes sec=none useless. The following patch makes sec=none force an anonymous mount. Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-04-30[CIFS] UID/GID override on CIFS mounts to SambaSteve French
When CIFS Unix Extensions are negotiated we get the Unix uid and gid owners of the file from the server (on the Unix Query Path Info levels), but if the server's uids don't match the client uid's users were having to disable the Unix Extensions (which turned off features they still wanted). The changeset patch allows users to override uid and/or gid for file/directory owner with a default uid and/or gid specified at mount (as is often done when mounting from Linux cifs client to Windows server). This changeset also displays the uid and gid used by default in /proc/mounts (if applicable). Also cleans up code by adding some of the missing spaces after "if" keywords per-kernel style guidelines (as suggested by Randy Dunlap when he reviewed the patch).

2007-04-25[CIFS] Add IPv6 supportSteve French
IPv6 support was started a few years ago in the cifs client, but lacked a kernel helper function for parsing the ascii form of the ipv6 address. Now that that is added (and now IPv6 is the default that some OS use now) it was fairly easy to finish the cifs ipv6 support. This requires that CIFS_EXPERIMENTAL be enabled and (at least until the mount.cifs module is modified to use a new ipv6 friendly call instead of gethostbyname) and the ipv6 address be passed on the mount as "ip=" mount option.

2006-09-30[CIFS] Do not send newer QFSInfo to legacy servers which can not support itSteve French
Fix dialect negotiation to save off when we have negotiated lanman. This allows us to avoid sending some somewhat newer requests that the server can not handle and go directly to the older version (infolevel) of the same call. Make sure we try to negotiate a level which allows us to get the server OS (which we check so we can detect Win9x vs. other legacy servers and eventually work around the Win9x DOS time bug (they reverse date/time fields).

2006-02-14[CIFS] SessionSetup cleanup part 2Steve French
The cifs session setup code has three cases, and a fourth for backlevel LANMAN2 style session setup needed to be added. This new session setup implmentation will eventually replace the other three and should be easier to read while fixing a few minor problems (not setting the LARGE READ/WRITEX flags when NTLMSSP was negotiated for example) and adding support for NTLMv2 (which will be added with the next patch. In the meantime, this code is marked in an CONFIG_CIFS_EXPERIMENTAL block and will not be turned on by default until it is tested against more server types.
