[PATCH RESEND] staging: greybus: loopback_test: Use scnprintf() for avoiding potential buffer overflow

by Takashi Iwai

Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf().

[PATCH -next 000/491] treewide: use fallthrough;

by Joe Perches

There is a new fallthrough pseudo-keyword macro that can be used to replace the various /* fallthrough */ style comments that are used to indicate a case label code block is intended to fallthrough to the next case label block. See commit 294f69e662d1 ("compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case use") These patches are intended to allow clang to detect missing switch/case fallthrough uses. Do a depth-first pass on the MAINTAINERS file and find the various F: pattern files and convert the fallthrough comments to fallthrough; for all files matched by all F: patterns in in each section. Done via the perl script below and the previously posted cvt_fallthrough.pl script. Link: https://lore.kernel.org/lkml/b56602fcf79f849e733e7b521bb0e17895d390fa.15822… These patches are based on next-20200310 and are available in git://repo.or.cz/linux-2.6/trivial-mods.git in branch

[PATCH] staging: greybus: Fix the irq API abuse

by Thomas Gleixner

Nothing outside of low level architecture code is supposed to look up interrupt descriptors and fiddle with them. Replace the open coded abuse by calling generic_handle_irq(). This still does not explain why and in which context this connection magic is injecting interrupts in the first place and why this is correct and safe, but at least the API abuse is gone.

[PATCH] staging: Replace zero-length array with flexible-array member

by Gustavo A. R. Silva

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") Signed-off-by: Gustavo A. R.

[PATCH] staging: greybus: use after free in gb_audio_manager_remove_all()

by Dan Carpenter

When we call kobject_put() and it's the last reference to the kobject then it calls gb_audio_module_release() and frees module. We dereference "module" on the next line which is a use after free.

[PATCH] staging: greybus: fix fw is NULL but dereferenced.

by Saurav Girepunje

Fix the warning reported by cocci check. Changes: In queue_work fw dereference before it actually get assigned. move queue_work before gb_bootrom_set_timeout. As gb_bootrom_get_firmware () return NEXT_REQ_READY_TO_BOOT only when there is no error and offset + size is actually equal to fw->size. So initialized next_request to NEXT_REQ_GET_FIRMWARE for return in other case.

[PATCH AUTOSEL 4.9 193/251] staging: greybus: light: fix a couple double frees

by Sasha Levin

From: Dan Carpenter <dan.carpenter(a)oracle.com> [ Upstream commit 329101244f214952606359d254ae883b7109e1a5 ] The problem is in gb_lights_request_handler(). If we get a request to change the config then we release the light with gb_lights_light_release() and re-allocated it. However, if the allocation fails part way through then we call gb_lights_light_release() again. This can lead to a couple different double frees where we haven't cleared out the original values: gb_lights_light_v4l2_unregister(light); ... kfree(light->channels); kfree(light->name); I also made a small change to how we set "light->channels_count = 0;". The original code handled this part fine and did not cause a use after free but it was sort of complicated to read.
