[PATCH] staging: greybus: audio_helper: remove unused and wrong debugfs usage

by Greg Kroah-Hartman

In the greybus audio_helper code, the debugfs file for the dapm has the potential to be removed and memory will be leaked. There is also the very real potential for this code to remove ALL debugfs entries from the system, and it seems like this is what will really happen if this code ever runs. This all is very wrong as the greybus audio driver did not create this debugfs file, the sound core did and controls the lifespan of it. So remove all of the debugfs logic from the audio_helper code as there's no way it could be correct. If this really is needed, it can come back with a fixup for the incorrect usage of the debugfs_lookup() call which is what caused this to be noticed at all.

[PATCH] staging: greybus: don't use index pointer after iter

by Karthik Alapati

There are some usages of index pointer of list(w) which may not point to the right entry when the required entry is not found and the list traversal completes with index pointer pointing to the last entry. So, use w_found flag to track the case where the entry is found. Currently, When the condition (w->dapm != dapm) is true the loop continues and when it is not then it compares the name strings and breaks out of the loop if they match with w pointing to the right entry and it also breaks out of loop if they didn't match by additionally setting w to NULL. But what if the condition (w->dapm != dapm) is never false and the list traversal completes with w pointing to last entry then usage of it after the iter may not be correct. And there is no way to know whether the entry is found. So, if we introduce w_found to track when the entry is found then we can account for the case where the entry is not actually found and the list traversal completes.

Unitialized Variable and Null Pointer Dereference bug in gb_bootrom_get_firmware

by Dongliang Mu

Hi maintainers, I would like to send one bug report. In gb_bootrom_get_firmware, if the first branch is satisfied, it will go to queue_work, leading to the dereference of uninitialized const variable "fw". If the second branch is satisfied, it will go to unlock with fw as NULL pointer, leading to a NULL Pointer Dereference. The Fixes commit should be [1], introducing the dereference of "fw" in the error handling code. I am not sure how to fix this bug. Any comment on removing the dereference of fw? [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -- My best regards to you. No System Is Safe! Dongliang Mu
