2017-02-01isdn: Convert obsolete cputime type to nsecsFrederic Weisbecker1-3/+3
Not sure if MISDN stats are ABI but it displays task cputime in cputime_t raw value regardless of what type cputime_t wraps which could be either jiffies, nsecs, usecs, or whatever random time unit. Plus it wrongly assumes that cputime_t is long. Given that this dump is broken anyway, lets just display the nanosec value and stick with that.

cputime This API returns a task's cputime in cputime_t in order to ease the conversion of cputime internals to use nsecs units instead. Blindly converting all cputime readers to use this API now will later let us convert more smoothly and step by step all these places to use the new nsec based cputime.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson1-1/+0
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

'struct timeval' uses 32-bit representation for seconds which will overflow in year 2038 and beyond. mISDN/clock.c needs to compute and store elapsed time in intervals of 125 microseconds. This patch replaces the usage of 'struct timeval' with 64-bit ktime_t which is y2038 safe. The patch also replaces do_gettimeofday() (wall-clock time) with ktime_get() (monotonic time) since we only care about elapsed time here.

From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported.

The icn, act2000 and pcbit drivers are all for very old hardware, and it is highly unlikely that anyone is actually still using them on modern kernels, if at all. All three drivers apparently are for hardware that predates PCI being the common connector, as they are ISA-only and active PCI ISDN cards were widely available in the 1990s. Looking through the git logs, it I cannot find any indication of a patch to any of these drivers that has been tested on real hardware, only cleanups or global API changes.

2016-03-05isdn: icn: remove a #warningArnd Bergmann1-1/+1
The icn driver currently produces an unconditional #warning whenever we build it, introduced by Karsten Keil back in 2003: #warning TODO test headroom or use skb->nb to flag ACK Karsten's original commit (from BitKeeper) contains this description: - here are lot of bugs left, so ISDN is not stable yet but I think it's really time to fix it, even if it need some cycles to get it right (normally I'm only send patches if it works 100% for me). - I add some additional #warnings to address places which need fixing (I hope that some of the other ISDN developer jump in) Apparently this has not happened, and it is unlikely that it ever will, given that the driver doesn't seem to work. No substantial bug fixes other than janitorial cleanups have happened in the driver since then, and I see no indication that anyone who patched it had the hardware. We should probably either remove the driver, or remove all of i4l, but for now, this shuts up the distracting #warning by turning it into a comment.

2016-02-19ser_gigaset: use container_of() instead of detourPaul Bolle1-8/+1
The purpose of gigaset_device_release() is to kfree() the struct ser_cardstate that contains our struct device. This is done via a bit of a detour. First we make our struct device's driver_data point to the container of our struct ser_cardstate (which is a struct cardstate). In gigaset_device_release() we then retrieve that driver_data again. And after that we finally kfree() the struct ser_cardstate that was saved in the struct cardstate. All of this can be achieved much easier by using container_of() to get from our struct device to its container, struct ser_cardstate. Do so. Note that at the time the detour was implemented commit b8b2c7d845d5 ("base/platform: assert that dev_pm_domain callbacks are called unconditionally") had just entered the tree. That commit disconnected our platform_device and our platform_driver. These were reconnected again in v4.5-rc2 through commit 25cad69f21f5 ("base/platform: Fix platform drivers with no probe callback"). And one of the consequences of that fix was that it broke the detour via driver_data. That's because it made __device_release_driver() stop being a NOP for our struct device and actually do stuff again. One of the things it now does, is setting our driver_data to NULL. That, in turn, makes it impossible for gigaset_device_release() to get to our struct cardstate. Which has the net effect of leaking a struct ser_cardstate at every call of this driver's tty close() operation. So using container_of() has the additional benefit of actually working.
