Arial?,?sans-serif?;color:blue?>Hello,</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>I committed our WDK and __ptr64 patch into
WinOF trunk, and WinOF and WinIB trunks were synchronized
again.</SPAN><o:p></o:p></P>
<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: "
Arial?,?sans-serif?;color:blue?>3. This revision
contains:</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?> 3.1. All bugfixes from WinOF trunk, from
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
poring, starting from rev. 2164</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?> 3.3. All bugfixes and patches from
connectx branches (both Mellanox and WinOF)</SPAN><o:p></o:p></P>
<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
connectx branch in WinIB).</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>We will appreciate your code review, just to
be sure that we didn't forget to insert any minor patch or bug
fix.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif?;color:blue?>4. I carefully tested new trunk inside
Mellanox, on different platforms, both with DDK and WDK compilers. Please,

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

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
:</SPAN><o:p></o:p></P>
<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 the same build machine, one has to update </SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif??>PLATFORM_SDK_PATH variable to point on the proper version
of SDK (for example,
PLATFORM_SDK_PATH=%sysdrive%:\PROGRA~1\MI2578~1\windows\v6.1)</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: "
Arial?,?sans-serif??>2.verify.src script in WDK (new add-on) checks if your
SOURCES file is in appropriate format.</SPAN><o:p></o:p></P>
<P><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: " Arial?,?sans-serif??>For
example, you can't set implicitly path to system .dll in TARGETLIBS, but to
