Input: cyttsp4 - avoid overflows when calculating memory sizes

2017-11-03T19:45:22Z

There are several places to perform subtraction to calculate buffer size such as: si->si_ofs.cydata_size = si->si_ofs.test_ofs - si->si_ofs.cydata_ofs; ... p = krealloc(si->si_ptrs.cydata, si->si_ofs.cydata_size, GFP_KERNEL); Actually, data types of above variables during subtraction are size_t, so it is unsigned. That means if second operand(si->si_ofs.cydata_ofs) is greater than the first operand(si->si_ofs.test_ofs), then resulting si->si_ofs.cydata_size could result in an unsigned integer wrap which is not desirable. The proper way to correct this problem is to perform a test of both operands to avoid having unsigned wrap. Signed-off-by: Vince Kim Signed-off-by: Dmitry Torokhov

Input: touchsceen - convert timers to use timer_setup()

2017-10-24T17:09:33Z

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. Signed-off-by: Kees Cook Signed-off-by: Dmitry Torokhov

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47Z

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

input / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-05T01:54:17Z

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. The alternative of CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME may be replaced with CONFIG_PM too. Make these changes in 2 files under drivers/input/. Signed-off-by: Rafael J.
