* w1: avoid recursive device_addDavid Fries2014-04-161-26/+6
| | | | | | | | | | | | | | | | | | | | | | | __w1_attach_slave_device calls device_add which calls w1_bus_notify which calls the w1_bq27000 slave driver, which calls platform_device_add and device_add and deadlocks on getting &(&priv->bus_notifier)->rwsem as it is still held in the previous device_add. This avoids the problem by processing the family add/remove outside of the slave device_add call. Commit 47eba33a0997fc7362a introduced this deadlock and added a KOBJ_ADD, as the add was already reported in device_register two add events were being sent. This change suppresses the device_register add so that any slave device sysfs entries are setup before the add goes out. Belisko Marek reported this change fixed the deadlock he was seeing on ARM device tree, while testing on my x86-64 system never saw the deadlock.

* w1: fix netlink refcnt leak on error pathDavid Fries2014-04-161-18/+26
| | | | | | | | | | | | | | | | | | | If the message type is W1_MASTER_CMD or W1_SLAVE_CMD, then a reference is taken when searching for the slave or master device. If there isn't any following data m->len (mlen is a copy) is 0 and packing up the message for later execution is skipped leaving nothing to decrement the reference counts. Way back when, m->len was checked before the search that increments the reference count, but W1_LIST_MASTERS has no additional data, the check was moved in 9be62e0b2fadaf5ff causing this bug. This change reorders to put the check before the reference count is incremented avoiding the problem.

* w1-gpio: handle of_get_gpio() returning -EPROBE_DEFER betterUwe Kleine-König2014-02-151-5/+14
| | | | | | | | | | | | | | | | | | of_get_gpio() might return -EPROBE_DEFER meaning that the driver providing the gpio isn't ready yet. If that happens for the first gpio the resulting kernel output without this patch is: w1-gpio somename: Failed to parse DT platform somename: Driver w1-gpio requests probe deferral The first message is misleading and so is suppressed with this patch. Further if determining the gpio to switch the external pullup yields -EPROBE_DEFER this error should be passed back to the caller instead of just continuing without pullup.

* w1: small type cleanup in sysfsDan Carpenter2014-02-151-2/+2
| | | | | | | | | | | | | On 64 bit systems, a large value for "long tmp" is truncated when assigning to "int md->max_slave_count" so we still end up with a value less than one despite the "tmp < 1" check. This is more of a problem for static checkers than a real life issue, but it's simple enough to fix.

* w1: hold bus_mutex in netlink and searchDavid Fries2014-02-083-5/+20
| | | | | | | | | | | | | The bus_mutex needs to be taken to serialize access to a specific bus. netlink wasn't updated when bus_mutex was added and was calling without that lock held, and not all of the masters were holding the bus_mutex in a search. This was causing the ds2490 hardware to stop responding when both netlink and /sys slaves were executing bus commands at the same time.

* w1: use family_data instead of rom in w1_slaveDavid Fries2014-02-082-3/+19
| | | | | | | | | | | | | | The first line printed from w1_slave gives the context of the w1 device. So does the second line, but if the CRC check failed, the second line contains the last successful result. It is confusing when it prints the temperature next to the line that might be a previous conversion and has nothing to do with that printed temperature value. Modify the code to store the last good conversion in family_data, which is designed for custom data structures.

| | | | | | | | | | | | | | | | | | | | | Before 63706172f33 "rework kthread_stop()" kthread_should_stop() always returned false when called from a non-kthread task, after it would oops as a non-kthread didn't have that structure and netlink was calling search from a thread which wasn't a kthread. 9d1817cab2f030 "w1: fix oops when w1_search is called from netlink connector", modified the code to avoid calling kthread_stop from a netlink thread. Introduce a w1_master flag and bit W1_ABORT_SEARCH to identify abort to cleanly support both kthread and netlink search abort. A search can take seconds to run, so it is important to abort early if the hardware is removed in the middle of a search.

* drivers: w1: make w1_slave::flags long to avoid memory corruptionMichal Nazarewicz2013-11-132-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On architectures where long is more then 32 bits, modifying a 32-bit field with set_bit (and other atomic bit operations) may cause bytes following the field to by modified. Because the endianness of the bits within a field is the native endianness of the CPU[1], on big-endian machines, bit number zero is in the last byte of the field. Therefore, `set_bit(0, ptr)' on a 64-bit big-endian machine is roughly equivalent to `((char *)ptr)[7] |= 1', and since w1 driver uses a 32-bit field for holding the flags, this causes bytes beyond the field to be modified. [1] From Documentation/atomic_ops.txt: Native atomic bit operations are defined to operate on objects aligned to the size of an "unsigned long" C data type, and are least of that size. The endianness of the bits within each "unsigned long" are the native endianness of the cpu.
