Hackers, what does hitting the following assert in vmspace_fork() imply? 3101 new_map = &vm2 ->vm_map ; 3102

copyinstr()

Hi, I was looking for some help with copyinstr() on an amd64 platform. My from address happens to be in the kernel (stack). I am getting an EFAULT, and I am wondering how to fix that. Would using memory from malloc() make a difference? -vijay ___ freeb

KVERIFY for non-debug invariants?

All. KASSERT() is a really need way of expressing invariants when INVARIANTS is defined. However for regular, non-INVARIANTS code folks have the typical if() panic() combos, or private macros. Would a KVERIFY() that does this in non-INVARIANTS code make sense? -vijay __

about freebsd boot1.S

hello all, i am trying to understand the freebsd boot code. i saw that the 1st stage boot loader relocates itself from 7c00 to 700. why is this done? if the run time kernel were to switch to real-mode and transfer control to this location (0700) would the 1st stage boot program run again? for t

jump from kernel to loader

hello, i have some exposure to the freebsd code, but not extensive. i am reading the sys/boot code, and saw that the 3 stage boot process involves a jump from the loader to the kernel in the last phase. i was wondering if it is possible to engineer the kernel to jump back to the loader in some

help with sendfile code

Hello hackers. What would be the FreeBSD 2.1 equivalent of the following sendfile code from uipc_syscalls.c for (off = uap->offset; ; off += xfsize, sbytes += xfsize) { vm_pindex_t pindex; vm_offset_t pgoff; pindex = OFF_TO_IDX(off); retry_l

Re: kqueue

Hi, this is in no way related to the kqueue question asked below but to event notification mechanisms in general. I was wondering if there is some paper or design that talks about how such a facility could be provided in a Unix type kernel. Kqueue is fairly recent, and I dont know what its require
