2023-03-17driver core: class: remove module * from class_create()Greg Kroah-Hartman1-1/+1
The module pointer in class_create() never actually did anything, and it shouldn't have been requred to be set as a parameter even if it did something. So just remove it and fix up all callers of the function in the kernel tree at the same time. Cc: "Rafael J.

Switch to use module_parport_driver() to reduce boilerplate code. Note, it doesn't matter when we check the module parameter.

2022-02-04pps: clients: gpio: Propagate return value from pps_gpio_probeRobert Hancock1-1/+1
If the pps-gpio driver was probed prior to the GPIO device it uses, the devm_gpiod_get call returned an -EPROBE_DEFER error, but pps_gpio_probe replaced that error code with -EINVAL, causing the pps-gpio probe to fail and not be retried later.

2019-07-16drivers/pps/pps.c: clear offset flags in PPS_SETPARAMS ioctlMiroslav Lichvar1-0/+8
The PPS assert/clear offset corrections are set by the PPS_SETPARAMS ioctl in the pps_ktime structs, which also contain flags. The flags are not initialized by applications (using the timepps.h header) and they are not used by the kernel for anything except returning them back in the PPS_GETPARAMS ioctl. Set the flags to zero to make it clear they are unused and avoid leaking uninitialized data of the PPS_SETPARAMS caller to other applications that have a read access to the PPS device.

2018-12-22treewide: surround Kconfig file paths with double quotesMasahiro Yamada1-2/+2
The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2018-02-06pps: parport: use timespec64 instead of timespecArnd Bergmann1-20/+20
getnstimeofday() is deprecated, so I'm converting this to use ktime_get_real_ts64() as a safe replacement. I considered using ktime_get_real() instead, but since the algorithm here depends on the exact timing, I decided to introduce fewer changes and leave the code that determines the nanoseconds since the last seconds wrap untouched. It's not entirely clear to me whether we should also change the time base to CLOCK_BOOTTIME or CLOCK_TAI. With boottime, we would be independent of changes due to settimeofday() and only see the speed adjustment from the upstream clock source, with the downside of having the signal be at an arbirary offset from the start of the UTC second signal. With CLOCK_TAI, we would use the same offset from the UTC second as before and still suffer from settimeofday() adjustments, but would be less confused during leap seconds. Both boottime and tai only offer usable (i.e. avoiding ktime_t to timespec64 conversion) interfaces for ktime_t though, so either way, changing it wouldn't take significantly more work. CLOCK_MONOTONIC could be used with ktime_get_ts64(), but would lose synchronization across a suspend/resume cycle, which seems worse.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook1-2/+2
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

Otherwise it is possible to enable it even on tickless system which has CONFIG_NO_HZ not set and CONFIG_NO_HZ_IDLE (or CONFIG_NO_HZ_FULL) set.

Call Trace: parport_unregister_driver+0x65/0xc0 [parport] SyS_delete_module+0x187/0x210 The sequence that builds up to this is: 1) plip is loaded and takes the parport device for exclusive use: plip0: Parallel port at 0x378, using IRQ 7. 2) pps_parport then fails to grab the device: pps_parport: parallel port PPS client parport0: cannot grant exclusive access for device pps_parport pps_parport: couldn't register with parport0 3) rmmod of pps_parport is then killed because it tries to access pardev->name, but pardev (taken from port->cad) is NULL.

2015-10-01ntp/pps: use y2038 safe types in pps_event_timeArnd Bergmann2-5/+3
The pps_event_time uses two 'timespec' structures internally, which suffer from the y2038 problem. The uses of this structure are fairly self-contained in the pps code, so this replaces them all at once. Unfortunately, this includes the sfc ethernet driver aside from the pps subsystem, so we change that one as well. Both touch the same data structure, and there probably is no good way to split the patch into smaller units. Acked-by: Richard Cochran <richardcochran@gmail.com> Acked-by: David S.

2015-10-01ntp/pps: use timespec64 for hardpps()Arnd Bergmann1-1/+3
There is only one user of the hardpps function in the kernel, so it makes sense to atomically change it over to using 64-bit timestamps for y2038 safety. In the hardpps implementation, we also need to change the pps_normtime structure, which is similar to struct timespec and also requires a 64-bit seconds portion. This introduces two temporary variables in pps_kc_event() to do the conversion, they will be removed again in the next step, which seemed preferable to having a larger patch changing it all at the same time.
