* e1000e 82574L related regression in 3.5, 3.6-rc (bisected)
From: Andre Tomt @ 2012-08-26 2:49 UTC (permalink / raw)
To: netdev, e1000-devel
3.5 broke the 82574L port on Intel DQ77KB motherboard.
Under a lot of loads the port will lock up for 1-2 seconds every few
seconds. Bidirectional 100Mbps TCP w/ gigabit link speed seems to
trigger it most often, especially when its traffic beeing forwarded.
Also it does not happen when port is saturated.
On 3.5 it seems TSO/GRO made it less likely to happen, but on 3.6-rc it
happens always and nearly instantly with the 100Mbps load.
The 82579LM port also driven by the same e1000e driver does not show
this behaviour.
Bisection turned up this commit as the one triggering this behaviour:

ifconfig/ethtool reports no dropped/errors. Packets just seem to get
held for a bit.

Commit c3def943c7117d42caaed3478731ea7c3c87190e have added support for
new pci ids of the 57840 board, while failing to change the obsolete value
in 'pci_ids.h'.
This patch does so, allowing the probe of such devices.

* [PATCH 0/5] dev_<level> and dynamic_debug cleanups
From: Joe Perches @ 2012-08-26 11:25 UTC (permalink / raw)
To: Andrew Morton, netdev
Cc: Greg Kroah-Hartman, David S. Miller, Jason Baron, Jim Cromie,
Kay Sievers, linux-kernel
The recent commit to fix dynamic_debug was a bit unclean.
Neaten the style for dynamic_debug.
Reduce the stack use of message logging that uses netdev_printk
Add utility functions dev_printk_emit and dev_vprintk_emit for /dev/kmsg.
Joe Perches (5):
dev_dbg/dynamic_debug: Update to use printk_emit, optimize stack
netdev_printk/dynamic_netdev_dbg: Directly call printk_emit
netdev_printk/netif_printk: Remove a superfluous logging colon
dev: Add dev_vprintk_emit and dev_printk_emit
device and dynamic_debug: Use dev_vprintk_emit and dev_printk_emit

In-Reply-To: <cover.1345978012.git.joe@perches.com>
commit c4e00daaa9
("driver-core: extend dev_printk() to pass structured data")
changed __dev_printk and broke dynamic-debug's ability to control the
dynamic prefix of dev_dbg(dev,..).
commit af7f2158fd
("drivers-core: make structured logging play nice with dynamic-debug")
made a minimal correction.
The current dynamic debug code uses up to 3 recursion levels via %pV.
This can consume quite a bit of stack. Directly call printk_emit to
reduce the recursion depth.
These changes include:
dev_dbg:
o Create and use function create_syslog_header to format the syslog
header for printk_emit uses.
o Call create_syslog_header and neaten __dev_printk
o Make __dev_printk static not global
o Remove include header declaration of __dev_printk
o Remove now unused EXPORT_SYMBOL() of __dev_printk
o Whitespace neatening
dynamic_dev_dbg:
o Remove KERN_DEBUG from dynamic_emit_prefix
o Call create_syslog_header and printk_emit
o Whitespace neatening

* [PATCH 2/5] netdev_printk/dynamic_netdev_dbg: Directly call printk_emit
From: Joe Perches @ 2012-08-26 11:25 UTC (permalink / raw)
To: Andrew Morton, David S. Miller, Jason Baron
Cc: Greg Kroah-Hartman, Jim Cromie, Kay Sievers, netdev, linux-kernel
In-Reply-To: <cover.1345978012.git.joe@perches.com>
A lot of stack is used in recursive printks with %pV.
Using multiple levels of %pV (a logging function with %pV
that calls another logging function with %pV) can consume
more stack than necessary.
Avoid excessive stack use by not calling dev_printk from
netdev_printk and dynamic_netdev_dbg. Duplicate the logic
and form of dev_printk instead.
Make __netdev_printk static.
Remove EXPORT_SYMBOL(__netdev_printk)
Whitespace and brace style neatening.

* [PATCH 3/5] netdev_printk/netif_printk: Remove a superfluous logging colon

To: Andrew Morton, Jason Baron

In-Reply-To: <cover.1345978012.git.joe@perches.com>
netdev_printk originally called dev_printk with %pV.
This style emitted the complete dev_printk header with
a colon followed by the netdev_name prefix followed
by a colon.
Now that netdev_printk does not call dev_printk, the
extra colon is superfluous. Remove it.
Example:
old: sky2 0000:02:00.0: eth0: Link is up at 100 Mbps, full duplex, flow control both
new: sky2 0000:02:00.0 eth0: Link is up at 100 Mbps, full duplex, flow control both

Looks good, if IDs are really supposed to be sent only from root
namespace. And you dropped PROC_EVENTS from init/Kconfig, but since it
was no, it should be ok by default.
Feel free to add my acked-by: Evgeniy Polyakov <zbr@ioremap.net>
Although I thoughs it could be more interesting to generate events
including namespace id

* [PATCH 06/15] userns: Convert audit to use kuid and kgid where appropriate
From: Eric W. Biederman @ 2012-08-26 13:00 UTC (permalink / raw)
To: linux-kernel
Cc: netdev, linux-fsdevel, Serge E. Hallyn, David Miller, Al Viro,

In-Reply-To: <87lih2h6i4.fsf@xmission.com>
- Explicitly deny permission for audit messages sent from processes
outside of the initial pid or user namespace. This removes the need
to format audit messages in other the initial user and pid namespaces.
- Explicitly format uids gids in audit messges in the initial user
namespace. This is safe because auditd is restrected to be in
the initial user namespace.
- Expliclty format pids in audit messages in the initial pid namespace.
This is safe because auditd is restricted to be in the initial pid
namespace.
- Modify audit_get_loginuid to return a kuid
- Modify /proc/<pid>/loginuid on read to convert the loginuid
into the user namespace of the opener of the file.
- Modify /proc/<pid>/loginud on write to convert the loginuid
from the user namespace of the opener of the file.
- In audit_krule store kuid_t values in a new uid field. Allowing
type safety when filtering on uids.
- In audit_krule store kgidt_t values in a new gid field. Allowing
type safety when filtering on gids.
- Get caller process uid and gid from the current task instead of the
NETLINK_CB. This results in simpler code yielding kuid_t and kgid_t
values. This is safe because netlink requests are now all processed
in the task of the sender.
- Convert audit_sig_uid into a kuid_t.
- Deny bitmask comparisons of uids and gids
- Introduce audit_uid_comparitor and audit_gid_compartor typesafe
variants of audit_compartor without the bitmask operations.
- Replace audit_compare_id with audit_compare_uid and audit_compare_gid.
This is one of those odd cases where being type safe and duplicating
code leads to simpler short and more concise code.
- For uid comparisons replace audit_comparator with audit_uid comparator.
- For gid comparisons replace audit_comparator with audit_gid_comparator.
The net result is that the audit subsystem now uses kuid_t and kgid_t whenever
possible making it almost impossible to confuse a raw uid_t with a kuid_t
preventing bugs.

Yes, the other Rx modes are PTP specific, and they don't make sense
unless the PTP clock is also enabled.
IIRC, on the Tx side, the 82580 can time stamp any marked packet
regardless of the packet contents, so this should also be always
available, along with HWTSTAMP_FILTER_ALL.

Hi John,
When VMDQ devices are opened over a virtual function which is
assigned to guest, the design should include a way to apply the
following ndo_set_vf_yyy calls to them
int (*ndo_set_vf_mac)(struct net_device *dev, int vf, u8* mac);
int (*ndo_set_vf_vlan)(struct net_device *dev, int vf, u16 vlan, u8 qos);
int (*ndo_set_vf_tx_rate)(struct net_device *dev, int vf, int rate);
int (*ndo_set_vf_spoofchk)(struct net_device *dev, int vf, bool setting);
Someone here suggested using a sub-index notation, that is m.n
represents vmdq device index = n on VF index = m where vf.0 is
the non vmdq VF device, makes sense? other thoughts?
Or.

It is more about where events are recevied rather than where events are
sent from.
With this change events continue to be sent from all processes but can
only be received by processes in the initial user and initial pid
namespace.
To processes in other namespaces the uids and pids that the proc
connector code puts into it's messages are just non-sense, so I
cause the registration of connector clients in other namespaces to fail.
All of that I can do easily without a complete reworking of the current
connector code. Which is enough for my current goal of building able
to build a kernel with all features enabled and only loosing features
if you are in somethin other than the initial namespaces.
> And you dropped PROC_EVENTS from init/Kconfig, but since it

The removal of PROC_EVENTS from init/Kconfig was removing of the compile
guard that kept PROC_EVENTS and USER_NS from being selected at the same
time. The curent user namespace code simply disables code that fails
to build when user namespace support is enabled.

> including namespace id
There isn't a namespace id. It is perfectly possible to generate events
that can be received by processes in multiple pid and user nameapces
just by calling pid_nr_ns() and from_kuid() with the right parameters.
The challenge is figuring out what namespaces have listening netlink
sockets we should send messages to.
Adding support for recepetion of connector proc events by listeners in
other namespaces looks like it would require near complete rewrite of
the connector code:
- Adding support for connector netlink sockets in other than the initial
network namespace.
- Tracking which sockets were opened in which pid and which user
namespaces.
- Filtering messages based on which namespaces the clients are listening
in.
- Generating the different messages for the different sets of clients.
When someone cares enough I am certain the code will get written.
Having a clear unambigous that configuration does not work is
the first step in getting there.
I presume that whatever listens to connector based proc events listens
for the appropriate ack when registering and the daemon will fail to
start up.

I assume the problem is patches 6 8 13 and 14 didn't make it through to
the mailling for some reason.
Just to see what is going on I you can look at my development branch
git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git userns-always-map-user-v48
Meanwhile I am going to scratch my head and try and resolve my technical
patch sending difficulties.

* [PATCH 0/2]: ieee802154 drivers location
From: Alexander Smirnov @ 2012-08-26 15:10 UTC (permalink / raw)
To: davem; +Cc: netdev, dbaryshkov
Please review these two patches:
1. I want to keep 'ieee802154' drivers with other networking code in
'drivers/net' folder instead of current location in drivers root.
I don't exactly know this historical reason, but lets keep networking
code together.
2. Minor cosmetic improvement in at86rf230 driver
With best regards,
Alex

The code under _init and _exit functions is similar to the code of
module_spi_driver macro, which is a wrapper to the module_driver macro,
so use it instead.

The IEEE 802.15.4 standard represents a networking protocol. I don't
exactly know why drivers for this protocol are stored into the root
'driver' folder, but better will be to store them with other
networking stuff. Currently there are only 3 drivers available for
IEEE 802.15.4 stack, so lets do it now with the smallest overhead.

We can certainly add a warning to the Kconfig text or (better) the
iptables manpage. But only a very small percentage of people who
might end up (unknowingly) using this will ever see them.
Feel free to send a patch though.

That seems reasonable to me. Adding a 'sub' argument to the set
routines should do it. Also the 'get' routines would need to be
extended to report back these virtual net devices.
int (*ndo_set_vf_mac)(struct net_device *dev, int vf, int sub, u8* mac);
int (*ndo_set_vf_vlan)(struct net_device *dev,
int vf, int sub,
u16 vlan, u8 qos);
int (*ndo_set_vf_tx_rate)(struct net_device *dev,
int vf, int sub,
int rate);
int (*ndo_set_vf_spoofchk)(struct net_device *dev,
int vf, int sub,
bool setting);
int (*ndo_get_vf_config)(struct net_device *dev,
int vf, int sub,
struct fila_vf_info *ivf)
I would need to check if any of the ixgbe/igb supported hardware can
support virtual device queues on virtual functions like this but I
presume if your looking at this you have some hardware that can.
I was hoping to get back to this in September, of course if someone
