* isdn: eicon: fix old-style declarationsArnd Bergmann2016-06-162-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Modern C standards expect the '__inline__' keyword to come before the return type in a declaration, and we get many warnings for this with "make W=1" because the eicon driver has this in a header file: eicon/divasmain.c:448:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/divasmain.c:453:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/divasmain.c:458:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/divasmain.c:463:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/divasmain.c:468:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/divasmain.c:473:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/platform.h:274:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] eicon/platform.h:280:1: error: '__inline__' is not at beginning of declaration [-Werror=old-style-declaration] A similar warning gets printed for the diva_os_register_io_port() declaration, because 'register' is interpreted as a keyword instead of a variable name: In file included from eicon/diva_didd.c:21:0: eicon/platform.h:206:1: error: 'register' is not at beginning of declaration [-Werror=old-style-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.

| * tty: Replace ASYNC_INITIALIZED bit and update atomicallyPeter Hurley2016-04-301-5/+5

* isdn: Use ktime_t instead of 'struct timeval'Tina Ruchandani2016-03-201-40/+29
| | | | | | | | | | | | | | '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.

From Jiri Pirko. 13) Hardware offload support for flower classifiers, from Amir Vadai. 14) Add "Local Checksum Offload".

The elapsed time, stored in secs and usecs, is part of the trace data the driver maintains for the DIVA Server ISDN cards. No change to the format of that time data is required. To avoid overflow on 32-bit systems use ktime_get_ts64() to return the elapsed monotonic time since system boot. This is a change from real to monotonic time. Since the driver only stores elapsed time, monotonic time is sufficient and more robust against real time clock changes. These new monotonic values can be more useful for debugging because they can be easily compared to other monotonic timestamps. Note elaspsed time values will now start at system boot time rather than module load time, so they will differ slightly from previously reported values. Remove declaration and init of previously unused time constants: start_sec, start_usec.

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.

* | ser_gigaset: use container_of() instead of detourPaul Bolle2016-02-191-8/+1

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.

On the other hand if the old code has been masking a real bug we would like to know about it. The check for tiocmset is kept because it is valid for a tty driver to have a NULL tiocmset method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 35a4a57 ("isdn: clean up debug format string usage") introduced a safeguard to avoid accidential format string interpolation of data when calling debugl1 or HiSax_putstatus. This did however not take into account VHiSax_putstatus (called by HiSax_putstatus) does *not* call vsprintf if the head parameter is NULL - the format string is treated as plain text then instead. As a result, the string "%s" is processed literally, and the actual information is lost. This affects the isdnlog userspace program which stopped logging information since that commit. So revert the HiSax_putstatus invocations to the previous state.

|/ | | | | | | | | | | | | | | | | | | The 'sc' ISDN driver relies on using readl() to access ISA I/O memory. This has been deprecated and produced warnings since linux-2.3.23, disabled by default since 2.4.10 and finally removed in 2.6.5. I found this because the compiling the driver for ARM produces a warning: In file included from ../drivers/isdn/sc/includes.h:8:0, from ../drivers/isdn/sc/init.c:13: ../arch/arm/include/asm/io.h:115:21: note: expected 'const volatile void *' but argument is of type 'long unsigned int' It is pretty clear that this driver has not been used for a long time and there is no point fixing it now, so let's remove it.

| * tty: Remove tty_wait_until_sent_from_close()Peter Hurley2015-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tty_wait_until_sent_from_close() drops the tty lock while waiting for the tty driver to finish sending previously accepted data (ie., data remaining in its write buffer and transmit fifo). tty_wait_until_sent_from_close() was added by commit a57a7bf3fc7e ("TTY: define tty_wait_until_sent_from_close") to prevent the entire tty subsystem from being unable to open new ttys while waiting for one tty to close while output drained. However, since commit 0911261d4cb6 ("tty: Don't take tty_mutex for tty count changes"), holding a tty lock while closing does not prevent other ttys from being opened/closed/hung up, but only prevents lifetime event changes for the tty under lock. Holding the tty lock while waiting for output to drain does prevent parallel non-blocking opens (O_NONBLOCK) from advancing or returning while the tty lock is held. However, all parallel opens _already_ block even if the tty lock is dropped while closing and the parallel open advances. Blocking in open has been in mainline since at least 2.6.29 (see tty_port_block_til_ready(); note the test for O_NONBLOCK is _after_ the wait while ASYNC_CLOSING). IOW, before this patch a non-blocking open will sleep anyway for the _entire_ duration of a parallel hardware shutdown, and when it wakes, the error return will cause a release of its tty, and it will restart with a fresh attempt to open. Similarly with a blocking open that is already waiting; when it's woken, the hardware shutdown has already completed to ASYNC_INITIALIZED is not set, which forces a release and restart as well. So, holding the tty lock across the _entire_ close (which is what this patch does), even while waiting for output to drain, is equivalent to the current outcome wrt parallel opens.

The changes outside of the typical drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and the introduction of ZONE_DEVICE + devm_memremap_pages(). Summary: - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic mechanism for adding device-driver-discovered memory regions to the kernel's direct map. This facility is used by the pmem driver to enable pfn_to_page() operations on the page frames returned by DAX ('direct_access' in 'struct block_device_operations'). For now, the 'memmap' allocation for these "device" pages comes from "System RAM". Support for allocating the memmap from device memory will arrive in a later kernel. - Introduce memremap() to replace usages of ioremap_cache() and ioremap_wt(). memremap() drops the __iomem annotation for these mappings to memory that do not have i/o side effects. The replacement of ioremap_cache() with memremap() is limited to the pmem driver to ease merging the api change in v4.3. Completion of the conversion is targeted for v4.4. - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem driver, update the VFS DAX implementation and PMEM api to provide persistence guarantees for kernel operations on a DAX mapping. - Convert the ACPI NFIT 'BLK' driver to map the block apertures as cacheable to improve performance. - Miscellaneous updates and fixes to libnvdimm including support for issuing "address range scrub" commands, clarifying the optimal 'sector size' of pmem devices, a clarification of the usage of the ACPI '_STA' (status) property for DIMM devices, and other minor fixes" * tag 'libnvdimm-for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (34 commits) libnvdimm, pmem: direct map legacy pmem by default libnvdimm, pmem: 'struct page' for pmem libnvdimm, pfn: 'struct page' provider infrastructure x86, pmem: clarify that ARCH_HAS_PMEM_API implies PMEM mapped WB add devm_memremap_pages mm: ZONE_DEVICE for "device memory" mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h dax: drop size parameter to ->direct_access() nd_blk: change aperture mapping from WC to WB nvdimm: change to use generic kvfree() pmem, dax: have direct_access use __pmem annotation dax: update I/O path to do proper PMEM flushing pmem: add copy_from_iter_pmem() and clear_pmem() pmem, x86: clean up conditional pmem includes pmem: remove layer when calling arch_has_wmb_pmem() pmem, x86: move x86 PMEM API to new pmem.h header libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option pmem: switch to devm_ allocations devres: add devm_memremap libnvdimm, btt: write and validate parent_uuid ...
