| * w1: mxc_w1: Fix timeout resolution problem leading to bus errorMartin Fuzzey2020-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c9723750a699c3bd465493ac2be8992b72ccb105 upstream. On my platform (i.MX53) bus access sometimes fails with w1_search: max_slave_count 64 reached, will continue next search. The reason is the use of jiffies to implement a 200us timeout in mxc_w1_ds2_touch_bit(). On some platforms the jiffies timer resolution is insufficient for this. Fix by replacing jiffies by ktime_get(). For consistency apply the same change to the other use of jiffies in mxc_w1_ds2_reset_bus().

| * USB: w1 ds2490: Fix bug caused by improper use of altsetting arrayAlan Stern2019-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c114944d7d67f24e71562fcfc18d550ab787e4d4 upstream. The syzkaller USB fuzzer spotted a slab-out-of-bounds bug in the ds2490 driver. This bug is caused by improper use of the altsetting array in the usb_interface structure (the array's entries are not always stored in numerical order), combined with a naive assumption that all interfaces probed by the driver will have the expected number of altsettings. The bug can be fixed by replacing references to the possibly non-existent intf->altsetting[alt] entry with the guaranteed-to-exist intf->cur_altsetting entry.

This is not permitted and made the driver non-working with vmapped stacks. Since all these transfers are done under the same bus_mutex lock we can simply use shared buffers in a device private structure for two most common of them. While we are at it, let's also fix a comparison between int and size_t in ds9490r_search() which made the driver spin in this function if state register get requests were failing.

Commit e93762bbf681 ("w1: masters: omap_hdq: add support for 1-wire mode") added a statement to clear the hdq_irqstatus flags in hdq_read_byte(). If the hdq reading process is scheduled slowly or interrupts are disabled for a while the hardware read activity might already be finished on entry of hdq_read_byte(). And hdq_isr() already has set the hdq_irqstatus to 0x6 (can be seen in debug mode) denoting that both, the TXCOMPLETE and RXCOMPLETE interrupts occurred in parallel. This means there is no need to wait and the hdq_read_byte() can just read the byte from the hdq controller. By resetting hdq_irqstatus to 0 the read process is forced to be always waiting again (because the if statement always succeeds) but the hardware will not issue another RXCOMPLETE interrupt. This results in a false timeout. After such a situation the hdq bus hangs. Link: http://lkml.kernel.org/r/b724765f87ad276a69625bc19806c8c8844c4590.1469513669.git.hns@goldelico.com Signed-off-by: H.

| | | | | | | | | | | | | The hardware search was failing without the COMM_RST flag. Enabled the flag and rewrote the function to handle more than one buffer of results and to continuing where the search left off. Remove hardware search note from the limitations now that it works. The "w1: ds2490 USB setup fixes" change went from 23.16 seconds to about 3 seconds, this takes the time for the search down to .307346 seconds.

| | | | | | | | | | | | | | | Calling usb_reset_configuration after usb_set_interface resets the interface that was just selected, so call reset first. Using alternative 3 greatly speeds the one wire search. alt 0 or 1, 10ms int, 23.16 seconds alt 2 or 3, 1ms int, 2.99 to 3.05 seconds Use usb_interrupt_msg not usb_bulk_msg as it is an interrupt pipe (bulk worked, it was just technically the wrong call).
