You forgot the namespace option to this call, what kernel version are
you using here?

Looks like the namespace for this link isn't valid.

What exactly are you trying to do here? Care to provide a pointer to

The driver core also uses this function, and it works there, so I'd
blame your code :)

I would rather introduce new helpers and convert users that really need
them.
For instance, just use a divide in BPF, because doing this on JIT might
be too complex for the gains. Strangely, libpcap doesn't seem to
optimize any divide, like divides by a power of two...
Reciprocal were added 7 years ago, for very specific uses, but current
cpus have reasonably fast dividers.

* [PATCH net-next 2/3] ipv6: add a flag to get the flow label used remotly
From: Florent Fourcot @ 2014-01-14 17:50 UTC (permalink / raw)
To: netdev; +Cc: Florent Fourcot
In-Reply-To: <1389721816-21165-1-git-send-email-florent.fourcot@enst-bretagne.fr>
This information is already available via IPV6_FLOWINFO
of IPV6_2292PKTOPTIONS, and them a filtering to get the flow label
information. But it is probably logical and easier for users to add this
here, and to control both sent/received flow label values with the
IPV6_FLOWLABEL_MGR option.

* [PATCH net-next 3/3] ipv6: add ip6_flowlabel_consistency sysctl
From: Florent Fourcot @ 2014-01-14 17:50 UTC (permalink / raw)
To: netdev; +Cc: Florent Fourcot
In-Reply-To: <1389721816-21165-1-git-send-email-florent.fourcot@enst-bretagne.fr>
With the introduction of IPV6_FL_F_REFLECT, there is no guarantee of
flow label unicity. This patch introduces a new sysctl to protect the old
behaviour, enable by default.

With this option, the socket will reply with the flow label value read
on received packets.
The goal is to have a connection with the same flow label in both
direction of the communication.

If I didn't miss something obvious this looks like a pretty possible

* [PATCH v3 net-next] bonding: handle slave's name change with primary_slave logic
From: Veaceslav Falico @ 2014-01-14 17:35 UTC (permalink / raw)
To: netdev; +Cc: Veaceslav Falico, Ding Tianhong, Jay Vosburgh, Andy Gospodarek
Currently, if a slave's name change, we just pass it by. However, if the
slave is a current primary_slave, then we end up with using a slave, whose
name != params.primary, for primary_slave. And vice-versa, if we don't have
a primary_slave but have params.primary set - we will not detected a new
primary_slave.
Fix this by catching the NETDEV_CHANGENAME event and setting primary_slave
accordingly. Also, if the primary_slave was changed, issue a reselection of
the active slave, cause the priorities have changed.

From: Vince Bridgers @ 2014-01-14 17:34 UTC (permalink / raw)
To: netdev; +Cc: peppe.cavallaro, rayagond, vbridgers2013
GRO requires VLANs to be removed before aggregation can occur.
The Synopsys EMAC does not strip VLAN tags so this must be
done by the driver.

Eric and Florian, could you look at this patch. When you say,
that it looks good, I will ask the user to validate it.
I can't reorder these actions, because it's reproduced on a real host
with real users. Thanks.
----
nf_conntrack_free can't be called for a conntract with non-zero ref-counter,
because it can race with nf_conntrack_find_get().
A conntrack slab is created with SLAB_DESTROY_BY_RCU. Non-zero
ref-conunter says that this conntrack is used now. So when we release a
conntrack with non-zero counter, we break this assumption.

I suspect you mean "reselecting" here, not "re-electing." I'd
add a couple more words, e.g., "reselecting active slave" to make it
clearer.

Without the commit id that is rather hard.
Does anything even get there without manual actions.
usb patches sit in a hidden limbo for ages.
I looked through my mailboxes and searched for the thread - but only
found the messages that included the one that said you'd send a patch
soon.
What I still don't understand is how I found the patch before!
The fact that work make me use outluck makes searching mail locally
almost impossible.
I might have to subscribe at home as well.

* [PATCH net-next v3 2/2] stmmac: Fix kernel crashes for jumbo frames
From: Vince Bridgers @ 2014-01-14 17:17 UTC (permalink / raw)
To: devicetree, netdev
Cc: peppe.cavallaro, robh+dt, pawel.moll, mark.rutland,
ijc+devicetree, galak, dinguyen, rayagond, vbridgers2013
In-Reply-To: <1389719859-29071-1-git-send-email-vbridgers2013@gmail.com>
These changes correct the following issues with jumbo frames on the
stmmac driver:
1) The Synopsys EMAC can be configured to support different FIFO
sizes at core configuration time. There's no way to query the
controller and know the FIFO size, so the driver needs to get this
information from the device tree in order to know how to correctly
handle MTU changes and setting up dma buffers. The default
max-frame-size is as currently used, which is the size of a jumbo
frame.
2) The driver was enabling Jumbo frames by default, but was not allocating
dma buffers of sufficient size to handle the maximum possible packet
size that could be received. This led to memory corruption since DMAs were
occurring beyond the extent of the allocated receive buffers for certain types
of network traffic.

which caused a system panic when changing the MTU.

* [PATCH net-next v3 1/2] dts: Add a binding for Synopsys emac max-frame-size
From: Vince Bridgers @ 2014-01-14 17:17 UTC (permalink / raw)
To: devicetree, netdev
Cc: peppe.cavallaro, robh+dt, pawel.moll, mark.rutland,

In-Reply-To: <1389719859-29071-1-git-send-email-vbridgers2013@gmail.com>
This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

* [PATCH net-next v3 0/2] stmmac: fix kernel crashes for jumbo frames
From: Vince Bridgers @ 2014-01-14 17:17 UTC (permalink / raw)
To: devicetree, netdev
Cc: peppe.cavallaro, robh+dt, pawel.moll, mark.rutland,
ijc+devicetree, galak, dinguyen, rayagond, vbridgers2013
v3:
* change snps,max-frame-size to max-frame-size
v2:
* change snps,max-mtu to snps,max-frame-size
These patches address two kernel crashes seen when using jumbo frames on
the Synopsys stmmac driver, and adds device tree configurability for the
maximum mtu. The Synopsys emac fifo sizes can be configured when a logic
design is synthesized, but does not provide a way for a driver to query the
exact fifo size.
The crashes seen were due to two issues.
1) The dma buffer size was being set after the dma buffers were allocated.
This caused a crash when changing the mtu since it was possible the buffers
would subsequently be freed using an incorrect dma buffer size. This could
also cause kernel panics due to memory corruption since a large mtu size could
have been configured, but the dma buffers were not sized accordingly.
2) Jumbo frames were being enabled by default, but the dma buffers were not
sized accordingly. This caused memory corruption in the context of certain
types of network traffic, leading to kernel panics.
I've tested these changes using automated, reproducible testware. I can
demonstrate the panics described before the fixes and show that the fixes
address the problems described.
Testing and improvements continue through the use of the mentioned automated
and reproducible testware.

* [RFC] sysfs_rename_link() and its usage
From: Veaceslav Falico @ 2014-01-14 17:17 UTC (permalink / raw)
To: linux-kernel; +Cc: netdev, gregkh, ebiederm
Hi,
I'm hitting a strange issue and/or I'm completely lost in sysfs internals.
Consider having two net_device *a, *b; which are registered normally.
Now, to create a link from /sys/class/net/a->name/linkname to b, one should
use:
sysfs_create_link(&(a->dev.kobj), &(b->dev.kobj), linkname);
To remove it, even simpler:
sysfs_remove_link(&(a->dev.kobj), linkname);
This works like a charm. However, if I want to use (obviously, with the
symlink present):
sysfs_rename_link(&(a->dev.kobj), &(b->dev.kobj), oldname, newname);
this fails with:
"sysfs: ns invalid in 'a->name' for 'oldname'"
in
608 struct sysfs_dirent *sysfs_find_dirent(struct sysfs_dirent *parent_sd,
...
615 if (!!sysfs_ns_type(parent_sd) != !!ns) {
616 WARN(1, KERN_WARNING "sysfs: ns %s in '%s' for '%s'\n",
617 sysfs_ns_type(parent_sd) ? "required" : "invalid",
618 parent_sd->s_name, name);
619 return NULL;
620 }
Code path:
warn_slowpath_fmt+0x46/0x50
sysfs_get_dirent_ns+0x30/0x80
sysfs_find_dirent+0x84/0x110
sysfs_get_dirent_ns+0x3e/0x80
sysfs_rename_link_ns+0x54/0xd0
I have no idea what this code means. Is there any reason for it to
fail (i.e. am I doing something wrong?) or I've hit a bug?
I've tested the only user of it (bridge) - and it works fine, however it's
not using its own net_device's kobject but rather its own dir.
Thank you!
