I've been looking there, but it doesn't exist and only open-dkim in freebsd 9.0. Is freebsd 9.0 no longer providing dkim-milter again in freebsd port.? Before I was use freebsd 8.2 for mail server, there are still exist dkim-milter. I finally install dkim-milter from source and manual compile. According to the dkim-milter project website: As of 2011-12-13, this project is no longer under active development. And: NOTE: dkim-milter has been replaced by OpenDKIM, available at http://opendkim.org/; And from the OpenDKIM website: The project started from a code fork of version 2.8.3 of the open source dkim-milter package developed and maintained by Sendmail, Inc. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
pmc(3): when are the counters updated?
Hi, folks. I'm trying to use pmc(3) to analyze code fragments, and
I've run into strange behavior: the counter values returned by
pmc_read(3) sometimes show no increment between readings, but are
updated a second later; even if the PMC in question was stopped
before.
Here's a test program:
#include sys/types.h
#include pmc.h
#include stdio.h
#include unistd.h
int main() {
pmc_id_t pmcid;
pmc_value_t value;
int i;
pmc_init();
pmc_allocate(instructions, PMC_MODE_TC, 0, PMC_CPU_ANY, pmcid);
pmc_start(pmcid);
for (i = 0; i 500; i++);
pmc_stop(pmcid);
pmc_read(pmcid, value);
printf(first reading: %lu\n, (unsigned long)value);
sleep(1);
pmc_read(pmcid, value);
printf(second reading: %lu\n, (unsigned long)value);
}
It's output on my system (FreeBSD 8.2 amd64, an Intel Atom processor)
is something like this:
first reading: 0
second reading: 15090110
I don't really like both numbers; I expect the first reading not
to be zero (there obviously are instructions between pmc_start and
pmc_stop), and I expect the second reading not to differ from the
first, as the PMC was stopped before both of them, so it's value
should not change.
So, what's going on here? Is this the intended behavior, or can it
be changed? And how do I get accurate readings?
(BTW, is this the right list for such questions?)

Kernel memory usage
I may be required to move this to embedded, but I am only looking for generalisation. Recently a thread came up on questions regarding memory usage, and a post was made regarding wired memory being nearly all kernel- something I was ready to dispute, but then I thought I'd better make sure. So I tested a few theories first off: 1. Comparing memory usage across machines I checked servers and desktops as well as vm's for memory usage, and I found some interesting results. On a firewall with no apps installed only 35M wired is used, on a desktop up to 700M~ can be used. Even as a dedicated server with a few services used it remains around 35M. Surely this means that the wired memory used is not just kernel? But I held off my assumptions as it was still plausible that the structures used by the kernel could balloon that far, too. 2. Stripped down, lean mean, kernel machine I then (using a vm I was building a kernel for anyway) stripped down a kernel in a VBox VM using le drivers for network to see what could be achieved. This is my kernel conf: include GENERIC ident VPN options IPSEC options IPSEC_DEBUG options IPSEC_NAT_T device crypto device enc # minimise kernel nooptions UFS_GJOURNAL nooptions MD_ROOT nooptions NFSCL nooptions NFSD nooptions NFSLOCKD nooptions NFS_ROOT nooptions MSDOSFS nooptions CD9660 nooptions PROCFS nooptions PSEUDOFS nodevice fdc nodevice mvs nodevice siis nodevice ahc nodevice ahd nodevice esp nodevice hptiop nodevice isp nodevice mpt nodevice mps nodevice sym nodevice trm nodevice adv nodevice adw nodevice aic nodevice bt nodevice ses nodevice amr nodevice arcmsr nodevice ciss nodevice dpt nodevice hptmv nodevice hptrr nodevice irr nodevice ips nodevice mly nodevice twa nodevice aac nodevice aacp nodevice ida nodevice mfi nodevice mlx nodevice twe nodevice tws nodevice splash nodevice cbb nodevice pccard nodevice cardbus nodevice uart nodevice ppc nodevice ppbus nodevice lpt nodevice plip nodevice ppi nodevice puc nodevice bxe nodevice de nodevice em nodevice igb nodevice ixgbe nodevice ti nodevice txp nodevice vx nodevice miibus nodevice ae nodevice age nodevice alc nodevice ale nodevice bce nodevice bfe nodevice bge nodevice dc nodevice et nodevice fxp nodevice jme nodevice lge nodevice msk nodevice nfe nodevice nge nodevice pcn nodevice re nodevice rl nodevice sf nodevice sge nodevice sis nodevice sk nodevice ste nodevice stge nodevice tl nodevice tx nodevice vge nodevice vr nodevice wb nodevice xl nodevice cs nodevice ed nodevice ex nodevice ep nodevice fe nodevice sn nodevice xe nodevice wlan nooptions IEEE80211_DEBUG nooptions IEEE80211_AMPDU_AGE nooptions IEEE80211_SUPPORT_MESH nodevice wlan_wep nodevice wlan_ccmp nodevice wlan_tkip nodevice wlan_amrr nodevice an nodevice ath nodevice ath_pci nodevice ath_hal nooptions AH_SUPPORT_AR5416 nodevice ath_rate_sample nodevice ipw nodevice iwi nodevice iwn nodevice malo nodevice mwl nodevice ral nodevice wi nodevice wpi nodevice md nooption USB_DEBUG nodevice uhci nodevice ohci nodevice ehci nodevice xhci nodevice usb nodevice uhid nodevice ukbd nodevice ulpt nodevice umass nodevice ums nodevice urio nodevice u3g nodevice uark nodevice ubsa nodevice uftdi nodevice uipaq nodevice uplcom nodevice uslcom nodevice uvisor nodevice uvscom nodevice aue nodevice axe nodevice cdce nodevice cue nodevice kue nodevice rue nodevice udav nodevice rum nodevice run nodevice uath nodevice upgt nodevice ural nodevice urtw nodevice zyd #nodevice firewire nodevice fwe nodevice fwip #nodevice dcons #nodevice dcons_rom nodevice sound nodevice snd_es137x nodevice snd_hda nodevice snd_ich nodevice snd_uaudio nodevice snd_via8233 World was also rebuilt as recommended by the handbook. As you can see I was rebuilding for IPSEC (for testing purposes only note). I couldn't remove dcons (not sure why- missing defined references), and that pulled in firewire too. The result was surprising: a 14M kernel became 6.3M, and when running I found it only used 19M used for wired (whoopee!) as opposed to 35M.
