[PATCH] crypto: inside-secure: Fix stability issue with Macchiatobin

by Pascal van Leeuwen

commit b8c5d882c833 upstream This patch should have made it into kernel version 5.4 as it fixes some major stability issue running on Marvell A7K/A8K, for which it was originally developed, which was introduced by an earlier patch. It is identical to the upstream patch, save for some whitespace fixes that were removed to not violate the "no trivial fixes" rule. Below follows the original patch text as submitted for kernel 5.5. This patch corrects an error in the Transform Record Cache initialization code that was causing intermittent stability problems on the Macchiatobin board. Unfortunately, due to HW platform specifics, the problem could not happen on the main development platform, being the VCU118 Xilinx development board. And since it was a problem with hash table access, it was very dependent on the actual physical context record DMA buffers being used, i.e. with some (bad) luck it could seemingly work quit stable for a while.

[PATCH] ext4: Fix ext4_empty_dir() for directories with holes

by Jan Kara

Function ext4_empty_dir() doesn't correctly handle directories with holes and crashes on bh->b_data dereference when bh is NULL. Reorganize the loop to use 'offset' variable all the times instead of comparing pointers to current direntry with bh->b_data pointer. Also add more strict checking of '.' and '..' directory entries to avoid entering loop in possibly invalid state on corrupted filesystems.

[PATCH 4.19 01/15] clk: at91: fix update bit maps on CFG_MOR write

by Lee Jones

From: Eugen Hristev <eugen.hristev(a)microchip.com> [ Upstream commit 263eaf8f172d9f44e15d6aca85fe40ec18d2c477 ] The regmap update bits call was not selecting the proper mask, considering the bits which was updating. Update the mask from call to also include OSCBYPASS. Removed MOSCEN which was not updated.

[PATCH 6/8] drm/panfrost: Make sure imported/exported BOs are never purged

by Boris Brezillon

We don't want imported/exported BOs to be purges, as those are shared with other processes that might still use them. We should also refuse to export a BO if it's been marked purgeable or has already been purged.

[PATCH for-4.19-stable] ath10k: restore QCA9880-AR1A (v1) detection
