patch "usb: typec: intel_pmc_mux: Do not configure SBU and HSL Orientation" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: typec: intel_pmc_mux: Do not configure SBU and HSL Orientation to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 7c6bbdf086ac7f1374bcf1ef0994b15109ecaf48 Mon Sep 17 00:00:00 2001 From: Utkarsh Patel <utkarsh.h.patel(a)intel.com> Date: Mon, 7 Sep 2020 17:21:52 +0300 Subject: usb: typec: intel_pmc_mux: Do not configure SBU and HSL Orientation in Alternate modes According to the PMC Type C Subsystem (TCSS) Mux programming guide rev 0.7, bits 4 and 5 are reserved in Alternate modes. SBU Orientation and HSL Orientation needs to be configured only during initial cable detection in USB connect flow based on device property of "sbu-orientation" and "hsl-orientation". Configuring these reserved bits in the Alternate modes may result in delay in display link training or some unexpected behaviour. So do not configure them while issuing Alternate Mode requests.

[PATCH v2 01/12] ima: Don't ignore errors from crypto_shash_update()

by Roberto Sassu

Errors returned by crypto_shash_update() are not checked in ima_calc_boot_aggregate_tfm() and thus can be overwritten at the next iteration of the loop. This patch adds a check after calling crypto_shash_update() and returns immediately if the result is not zero.

[PATCH v4.19.y 1/3] vfio/type1: Support faulting PFNMAP vmas

by Ajay Kaher

From: Alex Williamson <alex.williamson(a)redhat.com> commit 41311242221e3482b20bfed10fa4d9db98d87016 upstream. With conversion to follow_pfn(), DMA mapping a PFNMAP range depends on the range being faulted into the vma. Add support to manually provide that, in the same way as done on KVM with hva_to_pfn_remapped().

[PATCH 1/2] fs: Don't invalidate page buffers in block_write_full_page()

by Jan Kara

If block_write_full_page() is called for a page that is beyond current inode size, it will truncate page buffers for the page and return 0. This logic has been added in 2.5.62 in commit 81eb69062588 ("fix ext3 BUG due to race with truncate") in history.git tree to fix a problem with ext3 in data=ordered mode. This particular problem doesn't exist anymore because ext3 is long gone and ext4 handles ordered data differently. Also normally buffers are invalidated by truncate code and there's no need to specially handle this in ->writepage() code. This invalidation of page buffers in block_write_full_page() is causing issues to filesystems (e.g. ext4 or ocfs2) when block device is shrunk under filesystem's hands and metadata buffers get discarded while being tracked by the journalling layer. Although it is obviously "not supported" it can cause kernel crashes like: [ 7986.689400] BUG: unable to handle kernel NULL pointer dereference at +0000000000000008 [ 7986.697197] PGD 0 P4D 0 [ 7986.699724] Oops: 0002 [#1] SMP PTI [ 7986.703200] CPU: 4 PID: 203778 Comm: jbd2/dm-3-8 Kdump: loaded Tainted: G +O --------- - - 4.18.0-147.5.0.5.h126.eulerosv2r9.x86_64 #1 [ 7986.716438] Hardware name: Huawei RH2288H V3/BC11HGSA0, BIOS 1.57 08/11/2015 [ 7986.723462] RIP: 0010:jbd2_journal_grab_journal_head+0x1b/0x40 [jbd2] ...

The crash happens because bh->b_private is suddently NULL although BH_JBD flag is still set (this is because block_invalidatepage() cleared BH_Mapped flag and subsequent bh lookup found buffer without BH_Mapped set, called init_page_buffers() which has rewritten bh->b_private). So just remove the invalidation in block_write_full_page(). Note that the buffer cache invalidation when block device changes size is already careful to avoid similar problems by using invalidate_mapping_pages() which skips busy buffers so it was only this odd block_write_full_page() behavior that could tear down bdev buffers under filesystem's hands.
