The patch duplicates a lot of code. Do you really want these parts to be
modified independantly ?

* [PATCH] forcedeth: Poll for link changes
From: Manfred Spraul @ 2005-06-18 14:27 UTC (permalink / raw)
  To: Jeff Garzik; +Cc: Netdev

[-- Attachment #1: Type: text/plain, Size: 426 bytes --]

Hi Jeff,

Several users reported that the link speed detection is unreliable with 
nForce 3 nics. The result is either a completely dead network 
connection, or the connection dies after a few minutes.
The attached patch enables a timer that polls the PHY for link speed 
changes. The code already exists for nForce 1/2, the patch enables it 
for all nForce versions.

The last step can be just "git commit", and it will do the right thing
these days (and with a nice big warnign that it looks like you're
committing a merge).

In fact, it's much preferable that you use "git commit", because it will
also then remove the old MERGE_HEAD if the commit was successful, leaving
the state proper (so that subsequent "git commit" things don't think it's
a merge). It also makes it less likely that you forget your parents.
Maybe.

Yeah, something as simple as

	rm -f .merge_file_*

in git-resolve-script should fix it..

In fact, your last commit was broken, exactly because you had _not_ done 
this part right.

Your parent information was crap, meaning that when I pulled, I had to
re-merge. In fact, I'm going to undo this pull entirely, because of this -
it's simply _wrong_. You claim to have done a merge and indeed your "data"
is merged, but your history is totally buggered because you didn't do the 
proper parents.

Btw, this is serious. If you don't do proper parenting, you may have the
right _data_ in the tree, but because you lost sight of where that data
came from, all the commits leading up to that data (from the branch that
wasn't properly marked as a parent) are worthless and no longer reachable. 

In other words, it means that all the history leading up to the merge was
just lost, and you end up with just a magic "all these changes suddenly
appeared" patch that claims to be a merge, but is really just a big patch.

It also means that "git prune" will just delete the unreachable commits, 
since they are clearly not connected to anything any more. Also, any 
intermediate file contents (that were only reachable through those 
commits) are also unreachable and thus pruned. You literally end up with a 
situation where the "merge" is 100% equivalent to just taking the final 
patch, and applying it on top of the other head.

This may be the reason why you've had problems with "git prune". Your 
tree histories may be buggered, and you've lost the merges with me.

Quite frankly, I'd never have noticed, except:

 - because the history was buggered, the automated merge didn't find the 
   proper nearest parent, and thus it ended up finding a parent much 
   further back in history, which in turn meant that a trivial merge
   wasn't trivial any more, and I got a merge conflict on the
   drivers/net/r8169.c file.

 - actually looking at the history (with gitk, or by looking at how many 
   parents the commits have with "git log --pretty=raw") made it obvious 
   that your "merge" had only one parent.

This, btw, is one reason why I suggest against multiple branches, and run
git-fsck-cache --unreachable religiously. A bad merge with lost parents
normally causes unreachable commits, and that's a sure sign of trouble.

However, in your usage schenario, those commits are reachable in the
branch they originated in, and you mix it all up, so you'll never see the
warning signs.

I'm hoping my earlier pulls on your trees haven't resulted in these kinds 
of history losses before, and that this was the first time you did a merge 
and didn't specify the parents properly. Pls confirm..

You're being overly paranoid :)

This netdev-2.6.git episode was the first time I ever tried to use the 
conflict merging.  I didn't know git had improved to the point where 
"git commit" without any arguments would actually get things right.

All the other merges used the vanilla git-pull-script with no 
modifications.  Presumably it does the right thing :)

Yes.

Ok, I ended up re-doing the merge by hand (ie I fetched all the other 
parts, ignored your top entry, and just merged the previous one manually). 

I'm pushing out the result now, can you verify that the r8192.c file looks
like you expected it to look? I think it should be the same thing you
ended up with except for fixed parents, but...

  To: netdev
In-Reply-To: <20050617191340.GO22463@postel.suug.ch>

Thanks for your answers.
I just tried to compile the libnl, but some errors occured, so I'm just continuing without it.
But I've looked at the html documentation and it seems to be very good.

I repaired the main() function by adding the

rtMsg->rtm_family = AF_INET;
rtMsg->rtm_dst_len = 16;

but every request on any dst address in the routing table gives me this output:
Destination             Gateway         Interface               Source          Netmask
127.0.0.1               *.*.*.*                         lo              255.255.255.255

The 'rtm_dst_len = 16' should mean the mask of the route I'm looking for, correct? The whole code before sending the packet is below:


     /* Create Socket */
     if((sock = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_ROUTE)) < 0)
         perror("Socket Creation: ");

     /* Initialize the buffer */
     memset(msgBuf, 0, BUFSIZE);

     /* point the header and the msg structure pointers into the buffer */
     nlMsg = (struct nlmsghdr *)msgBuf;
     rtMsg = (struct rtmsg *)NLMSG_DATA(nlMsg);
     rtMsg->rtm_family = AF_INET;
     rtMsg->rtm_dst_len = 16;

     /* Fill in the nlmsg header*/
     nlMsg->nlmsg_len = NLMSG_LENGTH(sizeof(struct rtmsg)); // Length of message.
     nlMsg->nlmsg_type = RTM_GETROUTE;   // Get the routes from kernel routing table .
     nlMsg->nlmsg_flags = NLM_F_REQUEST;   // The message is a request for dump.
     nlMsg->nlmsg_seq = msgSeq++;   // Sequence of the message packet.
     nlMsg->nlmsg_pid = getpid();   // PID of process sending the request.

     char *cp;
     unsigned int xx[4]; int i = 0;
     unsigned char *ap = (unsigned char *)xx;
     for (cp = argv[1], i = 0; *cp; cp++) {
         if (*cp <= '9' && *cp >= '0') {
             ap[i] = 10*ap[i] + (*cp-'0');
             continue;
         }
         if (*cp == '.' && ++i <= 3)
             continue;
         return -1;
     }

Looks good here, thanks.

I re-did the merge locally, as a test, finalizing with 'git commit' 
rather than 'git-commit-tree ...' and the parent info came out correct. 
  FWIW.

Well, you can certainly do it by hand with git-commit-tree too, you just 
need to make sure that you give all the relevant parents, ie something 
like

	git-commit-tree $(git-write-tree) -p HEAD -p MERGE_HEAD

will do the right thing too (and is what "git commit" ends up doing in the 
end, of course).

In fact, the "git commit" script will _only_ handle the merge case of
having done a single "git pull", and if you do anything more complex that
has more than two parents, you'll have to go back to scripting the use of
git-commit-tree by hand.

I've considered trying to automate this a bit more: right now it really 
does depend on people and scripts always getting the parents right, but at 
least in theory I could embed the parent information in the "index" file 
at least as an additional safety-measure.

However, I'm not entirely sure that is a good idea: the current approach
is _extremely_ flexible, exactly because it allows you to do anything you
want with parents. That flexibility can be nice, but it's obviously also
what makes it a bit dangerous.

So the git approach is "give them rope", with a few scripts that handle 
the normal cases right. That's the unix way, after all..

This looks good but your NetlinkAddAttr is bogus, it should
be something like this:

int nl_msg_append_tlv(struct nlmsghdr *n, int type, void *data, size_t len)
{
	int tlen;
	struct rtattr *rta;
	
	tlen = NLMSG_ALIGN(n->nlmsg_len) + RTA_LENGTH(NLMSG_ALIGN(len));

	rta = (struct rtattr *) NLMSG_TAIL(n);
	rta->rta_type = type;
	rta->rta_len = RTA_LENGTH(NLMSG_ALIGN(len));

Your code is missing various alignment requirements. I can't tell
whether this is the last bug. I recommend you to read ip/iproute.c
in the iproute2 source or give libnl a second chance.

* [PATCH 0/9] orinoco updates
From: Christoph Hellwig @ 2005-06-18 23:27 UTC (permalink / raw)
  To: jgarzik, proski, hermes; +Cc: netdev

This is a tweleve patch series to bring orinoco in mainline uptodate with CVS.
I've also use the new ieee80211.h constants from the Jeff's wireless
tree, so the first patch brings over a copy of that one.

I'm mentioning the original authors wherever I could find them out, but most
patches actually consists of various CVS commits that belong together
logically.

* [PATCH 1/9] bring over ieee80211.h from mainline
From: Christoph Hellwig @ 2005-06-18 23:27 UTC (permalink / raw)
  To: jgarzik, proski, hermes; +Cc: netdev

the prototypes and inlines aren't actually needed, but let's not diverge
from -mm too far.

* [PATCH 4/9] orinoco: basic ethtool support
From: Christoph Hellwig @ 2005-06-18 23:27 UTC (permalink / raw)
  To: jgarzik, proski, hermes; +Cc: netdev

I completely reimplemented this based on ethtool_ops, CVS has an
ioctl-based version.

* [PATCH 7/9] orinoco: always use 802.11 header for rx processing
From: Christoph Hellwig @ 2005-06-18 23:28 UTC (permalink / raw)
  To: jgarzik, proski, hermes; +Cc: netdev


If the frame has ToDS flag set, mark it by setting skb->pkt_type to
PACKET_OTHERHOST, so that applications unaware of promiscous mode won't get
uplink (STA->AP) packets for STA->STA transmissions relayed by the AP.
Thanks to John Denker and David Gibson for finding the problem and the
solution.

Patch from Pavel Roskin
