NTFS Write Support GSoC - Week 8

Overwriting Files Continues

This week has been pretty uneventful. I wrote a function to shrink the allocation size of an attribute and another to migrate a resident attribute to non-resident. The former seems to be working, the latter still needs some work.

Google SoC lwIP Report Week 8

This past week started with me mindlessly chasing down memory bugs after having gotten WinDBG up and running. A particularly annoying bug involved an lwIP protocol control block being dereferenced by lwIP after it had been freed. I could not find a place in my drivere where I tried to use a dead PCB pointer, so I looked deeper. I did some stepping through of code, and read more of lwIP's source code.

NTFS Write Support GSoC - Week 7

Assigning Clusters Part 2

I can't believe week seven has already passed! Adding assigned clusters to data runs turned out to be more challenging than I anticipated, but I made steady progress on it throughout the week and have it working now (as far as I can tell). Fixing the problems with LargeMcb.c in week 1 came full-circle, as I relied on a map control block to simplify my task considerably.

USB stack improvements GSoC - Week 7

I'll start this report from the good news. After starting GSoC's coding period, I was doing fixes and improvements of hub layer and was not repeating tests which was done by me in community bonding period (results provided in my first blog post). So by the end of this week I decided to test surprise-removal on VBox with 2k3 working with our USB stack. As result I saw that crashes on device removal (physical) are gone! Even more after connection again, the USB flash and also composite device were performing well.
