"imply HWMON" was supposed to ensure that the SFP phy code can be built
with HWMON enabled or disabled while at the same time ensuring that
HWMON is not built as module if SFP is built into the kernel.
Unfortunately, that does not work as intended. With "allmodconfig", it
results in several unrelated HWMON drivers to be disabled instead of
being built as module as expected.
Let's use the old "depends on HWMON || HWMON=n" instead. This is slightly
different (it enforces SFP to be built as module if HWMON is built as
module), but it is better than the alternative of using "IS_REACHABLE()"
in the driver since that would disable sensor support if HWMON is built
as module and SFP is built into the kernel.

tcp: improve setsockopt() TCP_USER_TIMEOUT accuracy
The patch was becoming bigger based on feedback therefore I have
implemented a series of 3 commits instead in V4.
This series is a continuation based on V3 here and associated feedback:
https://patchwork.kernel.org/patch/10516195/
Suggestions by Neal Cardwell:
1) Fix up units mismatch regarding msec/jiffies.
2) Address possiblility of time_remaining being negative.
3) Add a helper routine tcp_clamp_rto_to_user_timeout() to do the rto
calculation.
4) Move start_ts logic into helper routine tcp_retrans_stamp() to
validate tcp_sk(sk)->retrans_stamp.
5) Some u32 declation and return refactoring.
6) Return 0 instead of false in tcp_retransmit_stamp(), it's not a bool.
Suggestions by David Laight:
1) Don't cache rto in tcp_clamp_rto_to_user_timeout().
Suggestions by Eric Dumazet:
1) Make u32 declartions consistent.
2) Use patch series for easier review.
3) Convert icsk->icsk_user_timeout to millisconds to avoid jiffie to
msec dance.
4) Use seperate titles for each commit in the series.
5) Fix fuzzy indentation and line wrap issues.
6) Make commit titles descriptive.
Changes:
1) Call tcp_clamp_rto_to_user_timeout(sk) as an argument to
inet_csk_reset_xmit_timer() to save on rto declaration.
Every time the TCP retransmission timer fires. It checks to see if
there is a timeout before scheduling the next retransmit timer. The
retransmit interval between each retransmission increases
exponentially. The issue is that in order for the timeout to occur the
retransmit timer needs to fire again. If the user timeout check happens
after the 9th retransmit for example. It needs to wait for the 10th
retransmit timer to fire in order to evaluate whether a timeout has
occurred or not. If the interval is large enough then the timeout will
be inaccurate.
For example with a TCP_USER_TIMEOUT of 10 seconds without patch:
1st retransmit:
22:25:18.973488 IP host1.49310 > host2.search-agent: Flags [.]
Last retransmit:
22:25:26.205499 IP host1.49310 > host2.search-agent: Flags [.]
Timeout:
send: Connection timed out
Sun Jul 1 22:25:34 EDT 2018
We can see that last retransmit took ~7 seconds. Which pushed the total
timeout to ~15 seconds instead of the expected 10 seconds. This gets
more inaccurate the larger the TCP_USER_TIMEOUT value. As the interval
increases.
Add tcp_clamp_rto_to_user_timeout() to determine if the user rto has
expired. Or whether the rto interval needs to be recalculated. Use the
original interval if user rto is not set.
Test results with the patch is the expected 10 second timeout:
1st retransmit:
01:37:59.022555 IP host1.49310 > host2.search-agent: Flags [.]
Last retransmit:
01:38:06.486558 IP host1.49310 > host2.search-agent: Flags [.]
Timeout:
send: Connection timed out

Some transmit modes require that the HW header is located in the same

the size of this contiguous header range, and enforce it when building

it matches the L3 code.

When checking whether an skb needs to be linearized to fit into an IO
buffer, it's desirable to consider the skb's final size and layout
(ie. after the HW header was added). But a subsequent linearization can
then cause the re-positioned HW header to violate its alignment
restrictions.
Dealing with this situation in two different code paths is quite tricky.
This patch integrates a) linearize-check and b) HW header construction
into one 3 step-sequence:
1. evaluate how the HW header needs to be added (to identify if it takes
up an additional buffer element), then
2. check if the required buffer elements exceed the device's limit.
Linearize when necessary and re-evaluate the HW header placement.
3. Add the HW header in the best-possible way:
a) push, without taking up an additional buffer element
b) push, but consume another buffer element
c) allocate a header object from the cache.

Improve on this by moving the allocation up to where the qeth card

placing the qeth card into netdev_priv().

card->dev is valid.

After the subdriver's remove() routine has completed, the card's layer

If qeth_dev_layer2_store() hits an error after remove() was called, the
card _always_ requires a setup(), even if the previous layer mode is
requested again.
But qeth_dev_layer2_store() bails out early if the requested layer mode
still matches the current one. So unless we reset the layer2 field,
re-probing the card back to its previous mode is currently not possible.

Make /sys/class/net per net namespace objects belong to container
This is a revival of an older patch set from Dmitry Torokhov:
https://lore.kernel.org/lkml/1471386795-32918-1-git-send-email-dmitry.torokhov@gmail.com/
My submission of v2 is here:
https://lore.kernel.org/lkml/1531497949-1766-1-git-send-email-tyhicks@canonical.com/
Here's Dmitry's description:
There are objects in /sys hierarchy (/sys/class/net/) that logically
belong to a namespace/container. Unfortunately all sysfs objects start
their life belonging to global root, and while we could change
ownership manually, keeping tracks of all objects that come and go is
cumbersome. It would be better if kernel created them using correct
uid/gid from the beginning.
This series changes kernfs to allow creating object's with arbitrary
uid/gid, adds get_ownership() callback to ktype structure so subsystems
could supply their own logic (likely tied to namespace support) for
determining ownership of kobjects, and adjusts sysfs code to make use
of this information. Lastly net-sysfs is adjusted to make sure that
objects in net namespace are owned by the root user from the owning
user namespace.
Note that we do not adjust ownership of objects moved into a new
namespace (as when moving a network device into a container) as
userspace can easily do it.
I'm reviving this patch set because we would like this feature for
system containers. One specific use case that we have is that libvirt is
unable to configure its bridge device inside of a system container due
to the bridge files in /sys/class/net/ being owned by init root instead
of container root. The last two patches in this set are patches that
I've added to Dmitry's original set to allow such configuration of the
bridge device.
Eric had previously provided feedback that he didn't favor these changes
affecting all layers of the stack and that most of the changes could
remain local to drivers/base/core.c. That feedback is certainly sensible
but I wanted to send out v2 of the patch set without making that large
of a change since quite a bit of time has passed and the bridge changes
in the last patch of this set shows that not all of the changes will be
local to drivers/base/core.c. I'm happy to make the changes if the
original request still stands.
* Changes since v2:
- Added my Co-Developed-by and Signed-off-by tags to all of Dmitry's
patches that I've modified
- Patch 1 received build failure fixes in
arch/x86/kernel/cpu/intel_rdt_rdtgroup.c
- Patch 2 was updated to drop the declaration of sysfs_add_file() from
sysfs.h since the patch removed all other uses of the function
- Patch 5 is a new patch that prevents tx_maxrate from being written
to from inside of a container
+ Maybe I'm being too cautious here but the restriction can always
be loosened up later
- Patches 6 and 7 were updated to make net_ns_get_ownership() always
initialize uid and gid, even when the network namespace is NULL, so
that it isn't a dangerous function to reuse
+ Requested by Christian Brauner
- I've looked at all sysfs attributes affected by this patch set and
feel comfortable about the changes. There are quite a few affected
attributes that don't have any capable()/ns_capable() checks in
their store operations (per_bond_attrs, at91_sysfs_attrs,
sysfs_grcan_attrs, ican3_sysfs_attrs, cdc_ncm_sysfs_attrs,
qmi_wwan_sysfs_attrs) but I think this is acceptable. It means that
container root, rather than specifically CAP_NET_ADMIN inside of the
network namespace that the device belongs to, can write to those
device attributes. It's the same situation that those devices have
today in that init root is able to write to the attributes without
necessarily having CAP_NET_ADMIN. I think that this should probably
be fixed in order to be consistent with what netdev_store() does by
verifying CAP_NET_ADMIN in the network namespace but that it doesn't
need to happen in this patch set.

Normally kobjects and their sysfs representation belong to global root,
however it is not necessarily the case for objects in separate namespaces.
For example, objects in separate network namespace logically belong to the
container's root and not global root.
This change lays groundwork for allowing network namespace objects
ownership to be transferred to container's root user by defining
get_ownership() callback in ktype structure and using it in sysfs code to
retrieve desired uid/gid when creating sysfs objects for given kobject.

Pull device mapper fix from Mike Snitzer:
"Fix DM writecache target to allow an optional offset to the start of
the data and metadata area.
This allows userspace tools (e.g. LVM2) to place a header and metadata
at the front of the writecache device for its use"
* tag 'for-4.18/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm writecache: support optional offset for start of device
The commit referred to below introduced an update of the link
capabilities field that is not safe. Given the recently added
feature to remove idle node and link items after 5 minutes, there
is a small risk that the update will happen at the very moment the
targeted link is being removed. To avoid this we have to perform
the update inside the node item's write lock protection.
Fixes: 9012de5089 ("tipc: add sequence number check for link STATE messages")
