<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>I committed our WDK and __ptr64 patch into WinOF

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>You can find below some further explanations
:</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>1. IBAL compiles now with WDK6001.18001.
According to Microsoft, it should be the last and official
release.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>We preserved the backward compatibility with
DDK, but some intermediate versions of WDK may be
incompatible</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>2. Please, be aware that one has to change WinOF
modules that aren't in WinIB stack (like additional ulps : udapl, vnic etc.)
according to new methodology</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>Also, I'd like to point your attention, that
these modules will work as is on homogeneous systems (x86, x64), but not on
mixed systems (x86 application on x64 kernel)</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>In addition, Microsoft fixed an internal
compiler bug when compiling modules with long (__ptr64) pointers on functions
(occurred only in x86 CHECKED environment).</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>So, you should not have problem with compilation
after adjusting makefiles</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "

rev. 939 to 1067</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?> 3.2. Mellanox __ptr64 solution and WDK

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?> 3.3. All bugfixes and patches from

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>It was a large amount of code to be merged from
4 different svn trees (trunk and connectx branch in WinOF, and trunk and

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>We will appreciate your code review, just to be

fix.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Hi
all,</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>It's a good
idea to clarify some points before announcing Mellanox patch for WDK porting and
__ptr64 problems.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Hope, these
explanations will be informative enough and not so long.</SPAN><o:p></o:p></P>
<P><B><U><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>1.
__ptr64 problem</SPAN></U></B><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Briefly
speaking, this problem arises when copying 32bit len pointer into 64bit len
pointer. In this case,</SPAN><U> </U><U><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>signed pointer
extension</SPAN></U> <SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif??>will take place.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>How it's
applicable to WinOF ? A lot of pointer were declared to be __ptr64 (i.e.,
to be always "long", even in 32bit kernel systems), that's to preserve on unique
size of structs used in IOCTL calls. The main problem it will cause is
between 32bit user applications and 64bit kernel
application.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>When user
code do operation like </SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>s_ptr =
&my_struct;</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>my_type*
__ptr64 ptr = s_ptr;</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Than kernel
will receive ptr with invalid upper bits data (4 bytes
FF).</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>To avoid
signed pointer extension, PtrToPtr64() function should be
used.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Also, I
found some other places where dangerous signed pointer extension took place,
even on 32bit kernel.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Yet another
problem that arises with __ptr64 attribute is internal compiler error
(C1001) in WDK when using __ptr64 pointer to function
(callback)</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>This
problem was described in ofw discussion, you can see also

style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??> (posted by Jan from
OFW)</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Our
solution:</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>1.
Initially, we decided to remove all __ptr64 attributes except those ones inside
IOCTL structures. After, put PtrToPtr64() conversion on every assignment to long
pointer.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>(like
my_type* __ptr64 ptr = PtrToPtr64(s_ptr); )</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>During this
solution, we changed a huge amount of code, so patch became unreadable. And it
was difficult to validate that all long pointer (with __ptr64 attribute) were
used in a proper manner</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>2. So, we
decided about another solution:</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??> All
__ptr64 occurrences were replaced by either:</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??> i)
TO_LONG_PTR(type, field) macro, when occurred inside
structure</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>ii)
VOID_PTR64 macro otherwise (defined as void macro)</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>#define
CONCAT(str1, str2) str1##str2</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>#define
TO_LONG_PTR(type,member_name) \</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif??> union { type member_name; uint64_t
CONCAT(member_name,_padding) ; }</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Thus, we
can both preserve on a uniform shapes of structs in user and kernel and to avoid
unsafe pointer arithmetic !</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>The patch
now is much more readable, but it sill consist of thousands
lines.</SPAN><o:p></o:p></P>

Migration to WDK</SPAN></U></B><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>Main issue
here was to preserve on backward compatibility with DDK</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>We were
able to compile our stack with WDK, while the main problems we found were

<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>1. WDK uses
newer version of SDK (SDK Vista). So, when using 2 or more versions of SDK on
