2011-02-17cifs: fix handling of scopeid in cifs_convert_addressJeff Layton
The code finds, the '%' sign in an ipv6 address and copies that to a buffer allocated on the stack. It then ignores that buffer, and passes 'pct' to simple_strtoul(), which doesn't work right because we're comparing 'endp' against a completely different string. Fix it by passing the correct pointer. While we're at it, this is a good candidate for conversion to strict_strtoul as well.

2011-01-20cifs: use get/put_unaligned functions to access ByteCountJeff Layton
It's possible that when we access the ByteCount that the alignment will be off. Most CPUs deal with that transparently, but there's usually some performance impact. Some CPUs raise an exception on unaligned accesses. Fix this by accessing the byte count using the get_unaligned and put_unaligned inlined functions. While we're at it, fix the types of some of the variables that end up getting returns from these functions.

2010-09-08cifs: prevent possible memory corruption in cifs_demultiplex_threadJeff Layton
cifs_demultiplex_thread sets the addr.sockAddr.sin_port without any regard for the socket family. While it may be that the error in question here never occurs on an IPv6 socket, it's probably best to be safe and set the port properly if it ever does. Break the port setting code out of cifs_fill_sockaddr and into a new function, and call that from cifs_demultiplex_thread.

2010-08-05CIFS: Make cifs_convert_address() take a const src pointer and a lengthDavid Howells
Make cifs_convert_address() take a const src pointer and a length so that all the strlen() calls in their can be cut out and to make it unnecessary to modify the src string. Also return the data length from dns_resolve_server_name_to_ip() so that a strlen() can be cut out of cifs_compose_mount_options() too.

2010-08-02cifs: set the port in sockaddr in a more clearly defined fashionJeff Layton
This patch should replace the patch I sent a couple of weeks ago to set the port in cifs_convert_address. Currently we set this in cifs_find_tcp_session, but that's more of a side effect than anything. Add a new function called cifs_fill_sockaddr. Have it call cifs_convert_address and then set the port. This also allows us to skip passing in the port as a separate parm to cifs_find_tcp_session. Also, change cifs_convert_address take a struct sockaddr * rather than void * to make it clearer how this function should be called.

2009-06-25cifs: have cifs parse scope_id out of IPv6 addresses and use itJeff Layton
This patch has CIFS look for a '%' in an IPv6 address. If one is present then it will try to treat that value as a numeric interface index suitable for stuffing into the sin6_scope_id field. This should allow people to mount servers on IPv6 link-local addresses.

2009-05-28cifs: make cnvrtDosUnixTm take a little-endian args and an offsetJeff Layton
The callers primarily end up converting the args from le anyway. Also, most of the callers end up needing to add an offset to the result. The exception to these rules is cnvrtDosCifsTm, but there are no callers of that function, so we might as well remove it.

2007-11-01[CIFS] when mount helper missing fix slash wrong direction in shareSteve French
Kernel bugzilla bug #9228 If mount helper (mount.cifs) missing, mounts with form like //10.11.12.13/c$ would not work (only mounts with slash e.g. //10.11.12.13\\c$ would work) due to problem with slash supposed to be converted to backslash by the mount helper (which is not there). If we fail on converting an IPv4 address in in4_pton then try to canonicalize the first slash (ie between sharename and host ip address) if necessary. If we have to retry to check for IPv6 address the slash is already converted if necessary. Signed-off-by: Steve French <sfrench@us.ibm.com>

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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
