Re: Problems mapping an vm_object to a process memory space

Hi Alexej, The actual mapping code is now at http://pastebin.com/m56a949a5 The objects in question are allocated through vm_pager_allocate with OBJT_SWAP. Note that I'm not sure when OBJ_ONEMAPPING clearing actually helps and when not -- I've more sprinkled it around the code in the ho

Re: Problems mapping an vm_object to a process memory space

hi , I had a problem with remapping too. Could I see your code? here is my code, that some times on AMD64 runs wrong : http://pastebin.com/m78da0b37 And now I solved the problem with remapping by using /dev/mem device. It has mmap syscal. And it seems to be working without problem. Alexej < 2009

Bug in tcp wrappers?

I think I've found a bug in libwrap/tcpwrappers. Before filing an actual bug report I want to get some feedback here first. A hosts.allow file with ~1000 ips on a single line (Haven't experimented with other quantities yet), causes network daemons that use libwrap stop accepting incoming netwo

intpm: multiple salves, collision ??

I observe some quite odd behavior with intpm(4). I have a program that access two slaves at a high rate (no sleeps or long calculations). The typical pattern of access is: 1. SMB_WRITEB slave1 reg1 2. SMB_READB slave1 reg2 3. SMB_READB *slave2* reg 4. SMB_READB slave1 reg3 There are many iteratio

Problems mapping an vm_object to a process memory space

As a part of a research project, I'm trying to build publish/subscribe shared memory semantics where the idea is to first map an vm_object as read/write to a publisher's memory space, and then a COW shadow of that later to the subscriber processes' memory space. I've got to the point where
