I would definitely prefer that to using ndis.

My experiences converting a couple of systems from 9-STABLE to 10-STABLE 
over the last couple of months were really pretty easy.  These were 
source updates for both base and ports.  Despite changing from pkg_* to 
pkg and KMS X drivers at the same time, it was surprisingly smooth.


If you have devel/ccache installed, remove it before starting, though, 
it has problems with clang.  Using -DNOCLEAN with an existing /usr/obj 
can go even faster than ccache: less than two minutes for a buildworld 
on my frequently updated i5/SSD system, sometimes less than one minute.

 A)
 Clang is needed to compile FreeBSD 10 due to use of the updated libstdc++ in 
 world.

Ehrm, no?  You should be able to run stock 9-stable, which has gcc as
the default compiler, and build 10.0 release without any trouble.

Can you please explain which problems you encountered with libstdc++?

lock order reversals w/ backtrace

2014-01-23 Thread Thomas Hoffmann
A few days ago I started running 11.0-CURRENT at r260971 for the first time.

The last couple of times I shutdown my system I noticed 2 or 3 short lock
order reversal messages with accompanying backtraces scroll by. Do these
messages represent a problem that I should report or can I ignore them as
debug in nature? If I should report them, how or where do these messages
get logged? I can find no reference to them in syslog or anywhere else upon
my subsequent reboot.

I also had a couple of these messages pop up the other day while
mounting/umounting USB thumb drives. I did not think anything of them at
the time as the mounts/umounts completed successfully.

Please advise. Thanks.

I moved to pkg after the upgrade from 9.2 to 10.0 and had no real problems.
Of course, I did have to  install pkg and run pkg2ng, but I would have had
to run those at some point, anyway.

Exactly what problems did you hit?

Yes.  Removing /usr/obj is a faster way of doing 'make clean', mostly.

Yes, because make will see that many/most files have already been built.

Hi,

Can you see if you can snap some keywords of the backtraces, like usb_xxx 
usbdx_xxx cam scsi or something like that.

Else I believe there are some sysctl options to prevent the final reboot 
somehow so that you can write down the messages.

Hmm, I particularly like your suggestion of running a full buildworld
periodically. With two hour buildworlds (from scratch) I was planning on
rebuilding every couple of weeks. If using -DNOCLEAN can significantly
reduce my buildworld time, I'll rebuild weekly and do a full build every
fourth week. I'm anxious to give this approach a go and see how much time I
can save on the buildworlds.

Thanks for the info and tips.

 If you always clear your /usr/obj, you can safely add -DNOCLEAN to the
 build and it will shave off a minute or two (depending on drive speed)
 that would have been spent attempting to delete thousands of non-
 existent files and directories. I've never actually benchmarked, but rm
 -rf /usr/obj followed by make -DNOCLEAN buildworld should take slightly
 less time than a regular buildworld (unless perhaps you use a tmpfs
 backed /usr/obj).

 Yes, you can safely do a make -DNOCLEAN bulidworld without first
 clearing out /usr/obj iff conditions are right. If you change anything
 in src.conf or make.conf, then you must clean. If you switch what
 branch you are checking out from then you must clean. If you are
 tracking -STABLE or -CURRENT with regularity (as Warren does) then you
 can usually get away with not cleaning. If you go too long between
 updates to your /usr/src then you might have to clean. If there is a
 disruptive commit, you might have to clean. Sometimes it will be
 obvious because the buildworld won't complete without error, but
 sometimes it will finish with apparent success however some binaries
 will be bad. So, if you get some rather strange behavior shortly after
 installworld, go clean it and build again.

 If you are doing your own local development, then you can safely use
 -DNOCLEAN throughout the process. Only if you make a disruptive
 change yourself or possibly if you merge changes from svn would you
 need to clean the build.


This is good to know, especially the info on when using -DNOCLEAN might
cause problems and how they might manifest themselves. Thanks.

  Yes, I think this would work fine.  I think setting SELTD_RESCAN as a way

  do it is fine as well.
 
 excellent, thanks.
 
 I also have two related questions:
 
 1. why isn't the struct mtx part of the struct selinfo instead
of being grabbed from the mtxpool_select ?

I think this is because there is no selinfo_init() and no selinfo_destroy(),
so there is no way to manage the lifetime of the mutex were it embedded into
the structure.  Also, if there are a lot of these structures, but only a
subset of them are ever accessed, then a smaller set of locks that are
hashed onto the structures may work just fine without introducing extra
contention (but with the benefit of saving space in the structures).

 2. am i correct that we do need to protect concurrent invocations
of selrecord() on the same selinfo because mtx_pool_find()
return the same mutex for a given struct selinfo ?

If you mean 'do not need', yes.  mtx_pool_find() does a hash on the address,
so it will always return the same lock for a given selinfo, and no external
locking should be needed by callers.  However, callers often need to check
other state for which they need to hold a lock anyway.  OTOH, if, for example,
socket buffer locks were reader/writer locks, sopoll_generic() could use
read locks on the socket buffers even while calling selrecord().

 In case, any objections if i add some comments to the code
 to explain the above ?

Not from me. :)

port hyperic-sigar - marked broken, is anybody fixing this port?

2014-01-23 Thread Werner Thie

Hi

Java is probably not the first programming language which comes to mind, 
when working with FreeBSD. But still I sadly had to forgive to deploy 
OpenKM because it can't start LibreOffice as service due to the fact, 
that the author used hyperic-sigar for this functionality.


My question: Is anybody working on this problem, that instead of using 
utmp.h and diddling with the related files directly, one should rely on 
utmpx.h and its db manipulating functionality.


I could give it a try for FreeBSD9, but I'm mostly a noob, be it Java or 
Java extensions and also for ports.


Maybe some kindred soul could fill me in such, that this itch can be 
scratched.

Hi,

yes. I'm going to deprecate NDIS and yes, this means that people using
hardware that doesn't have a driver will have to go without. It sucks,

Re: Freebsd 11 current testing ndis / kldload: bcmwl564_sys.ko PANIC

2014-01-23 Thread Miguel Clara
Pity this is not an old laptop... I7 processor sadly a bad wifi card,
gave all kinds of problems on Windows to be honest!

No point on applying the patch then if it will stop working anyway!
I think I might be able to substitute the card with one from another
asus, unless BIOS doesn't allow me too!

thanks for clarifying!

 Hi,

 yes. I'm going to deprecate NDIS and yes, this means that people using
 hardware that doesn't have a driver will have to go without. It sucks,
 but noone has stepped up to maintain NDIS and it can't work for later
 NDIS APIs.

 Hi Adrian, when you say I'm going to deprecate NDIS, does this also
 mean there a change to have this driver working without ndis in
 freebsd?

 I tried
 kldload if_bwi
 kldload if_bwn

 But none of them work for 4313 it seems! :(

 OTOH, the FPU save support would be cool.

CAM Target Layer (LUN masking)

Configuring and Running CTL:

 Note that all CTL LUNs are presented to all frontends.  There is no
 LUN masking, or separate, per-port configuration.
.

Are there any plans to implement any kind of zoning or lun

masking?

It is very desirable feature for the project I'm working on now. Now I'm

surfing isp's sources trying to get its architecture. I'd like to contribute

in this filed (development, testing, whatever) if possible. Please let me

know if I can help or if someone has beta-versions to try and fix.

Thanks
Sergey
