Which never made it to the list apparently. I'll just blame spam
filtering and provide it an alternative way:
http://www.stack.nl/~ariane/vmmap_sys.diff.63
SHA256 (vmmap_sys.diff.63) =
5c3e71360795f3899baa652f6ba6caa999b137b01a778dca12c253af1dbcff00
MD5 (vmmap_sys.diff.63) = 11736a0bacb0b8b72079935ba01c62c4
size: 305720 bytes
Highlights:
- the mapping and allocation (address selection) logic is split
- the allocator is in compatibility mode, meaning it ought to perform
the same strategies (and hence contain the same bugs, yay) as the
version that you are running in your kernel at the moment
(this means java and various browsers won't die horribly, at least not
more than they used to)
- despite using the same algorithm, it is a bit^W alot faster
- it's only a 3^W 10494 line diff :P
I'll need testing on any and all architectures.
Thanks,
Hi, I've tried both patches on i386. The system crashed.
The code in src is a clean checkout from 3 January. I applied the patches
in src and src/sys without errors.
I compiled the kernel and userland with this steps:
export PARALLEL_BUILD=YES
export MAKE_JOBS=2
cd /usr/src/sys/arch/i386/conf
config GENERIC.MP
cd ../compile/GENERIC.MP
make clean
make
make install
rm -rf /usr/obj/*
cd /usr/src
make obj
cd /usr/src
make build
dmesg with trace and ps:
http://juanfra.info/bugs-y-listas/obsd-vmmap-201201/dmesg.txt.bz2
When I boot the system with /obsd (from snapshots) and the userland with
your patch applied, all works without issues.
I will save the dump for a few weeks. If you need more info, ask me.
Cheers.
