git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux Pull RTC updates from Alexandre Belloni: "A huge series from me this cycle. I went through many drivers to set the date and time range supported by the RTC which helps solving HW limitation when the time comes (as early as next year for some). This time, I focused on drivers using .set_mms and .set_mmss64, allowing me to remove those callbacks. About a third of the patches got reviews, I actually own the RTCs and I tested another third and the remaining one are unlikely to cause any issues. Other than that, a single new driver and the usual fixes here and there.

While PCAP_RTC_DAY_MASK is set to 0x3ffff, it is very unlikely to be correct as this ends in june 1992, before the product even existed. It is more likely to be a 14-bit day counter. The next product in the family (the mc13xxx) has a 15-bit day counter. The same issue is seen with PCAP_RTC_TOD_MASK which only has 65535 seconds and falls short of the necessary 86400 seconds.

2019-05-06*: convert stream-like files from nonseekable_open -> stream_openKirill Smelkov2-2/+2
Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af3422 ("fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock"), search and convert to stream_open all in-kernel nonseekable_open users for which read and write actually do not depend on ppos and where there is no other methods in file_operations which assume @offset access. I've verified each generated change manually - that it is correct to convert - and each other nonseekable_open instance left - that it is either not correct to convert there, or that it is not converted due to current stream_open.cocci limitations. The script also does not convert files that should be valid to convert, but that currently have .llseek = noop_llseek or generic_file_llseek for unknown reason despite file being opened with nonseekable_open (e.g. drivers/input/mousedev.c) Among cases converted 14 were potentially vulnerable to read vs write deadlock (see details in 10dce8af3422): drivers/char/pcmcia/cm4000_cs.c:1685:7-23: ERROR: cm4000_fops: .read() can deadlock .write();

2019-04-29rtc: 88pm860x: prevent use-after-free on device removeSven Van Asbroeck1-1/+1
The device's remove() attempts to shut down the delayed_work scheduled on the kernel-global workqueue by calling flush_scheduled_work(). Unfortunately, flush_scheduled_work() does not prevent the delayed_work from re-scheduling itself. The delayed_work might run after the device has been removed, and touch the already de-allocated info structure. This is a potential use-after-free. Fix by calling cancel_delayed_work_sync() during remove(): this ensures that the delayed work is properly cancelled, is no longer running, and is not able to re-schedule itself. This issue was detected with the help of Coccinelle. Signed-off-by: Sven Van Asbroeck <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]>
