[PATCH v2] kbuild: Fix changing ELF file type for output of gen_btf for big endian

by Nathan Chancellor

Commit 90ceddcb4950 ("bpf: Support llvm-objcopy for vmlinux BTF") changed the ELF type of .btf.vmlinux.bin.o to ET_REL via dd, which works fine for little endian platforms: 00000000 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 |.ELF............| -00000010 03 00 b7 00 01 00 00 00 00 00 00 80 00 80 ff ff |................| +00000010 01 00 b7 00 01 00 00 00 00 00 00 80 00 80 ff ff |................| However, for big endian platforms, it changes the wrong byte, resulting in an invalid ELF file type, which ld.lld rejects: 00000000 7f 45 4c 46 02 02 01 00 00 00 00 00 00 00 00 00 |.ELF............| -00000010 00 03 00 16 00 00 00 01 00 00 00 00 00 10 00 00 |................| +00000010 01 03 00 16 00 00 00 01 00 00 00 00 00 10 00 00 |................| Type: <unknown>: 103 ld.lld: error: .btf.vmlinux.bin.o: unknown file type Fix this by updating the entire 16-bit e_type field rather than just a single byte, so that everything works correctly for all platforms and linkers. 00000000 7f 45 4c 46 02 02 01 00 00 00 00 00 00 00 00 00 |.ELF............| -00000010 00 03 00 16 00 00 00 01 00 00 00 00 00 10 00 00 |................| +00000010 00 01 00 16 00 00 00 01 00 00 00 00 00 10 00 00 |................| Type: REL (Relocatable file) While in the area, update the comment to mention that binutils 2.35+ matches LLD's behavior of rejecting an ET_EXEC input, which occurred after the comment was added.

[PATCH] wifi: nl80211: reject iftype change with mesh ID change

by Johannes Berg

From: Johannes Berg <johannes.berg(a)intel.com> It's currently possible to change the mesh ID when the interface isn't yet in mesh mode, at the same time as changing it into mesh mode. This leads to an overwrite of data in the wdev->u union for the interface type it currently has, causing cfg80211_change_iface() to do wrong things when switching. We could probably allow setting an interface to mesh while setting the mesh ID at the same time by doing a different order of operations here, but realistically there's no userspace that's going to do this, so just disallow changes in iftype when setting mesh ID.

[PATCH 06/17] drm/amd/display: adjust few initialization order in dm

by Rodrigo Siqueira

From: Wayne Lin <wayne.lin(a)amd.com> [Why] Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work" when boot up with a mst tbt4 dock connected. After analyzing, there are few parts needed to be adjusted: 1. hpd_rx_offload_wq[].aconnector is not initialzed before the dmub outbox hpd_irq handler get registered which causes the error message. 2. registeration of hpd and hpd_rx_irq event for usb4 dp tunneling is not aligned with legacy interface sequence [How] Put DMUB_NOTIFICATION_HPD and DMUB_NOTIFICATION_HPD_IRQ handler registration into register_hpd_handlers() to align other interfaces and get hpd_rx_offload_wq[].aconnector initialized earlier than that.

[PATCH 3/3] btrfs: dev-replace: properly validate device names

by David Sterba

There's a syzbot report that device name buffers passed to device replace are not properly checked for string termination which could lead to a read out of bounds in getname_kernel(). Add a helper that validates both source and target device name buffers. For devid as the source initialize the buffer to empty string in case something tries to read it later. This was originally analyzed and fixed in a different way by Edward Adam Davis (see links).

[PATCH 4.19 5.4 5.10 5.15 6.1] nilfs2: fix hang in nilfs_lookup_dirty_data_buffers()

by Ryusuke Konishi

commit 38296afe3c6ee07319e01bb249aa4bb47c07b534 upstream. Syzbot reported a hang issue in migrate_pages_batch() called by mbind() and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2. While migrate_pages_batch() locks a folio and waits for the writeback to complete, the log writer thread that should bring the writeback to completion picks up the folio being written back in nilfs_lookup_dirty_data_buffers() that it calls for subsequent log creation and was trying to lock the folio. Thus causing a deadlock. In the first place, it is unexpected that folios/pages in the middle of writeback will be updated and become dirty. Nilfs2 adds a checksum to verify the validity of the log being written and uses it for recovery at mount, so data changes during writeback are suppressed. Since this is broken, an unclean shutdown could potentially cause recovery to fail. Investigation revealed that the root cause is that the wait for writeback completion in nilfs_page_mkwrite() is conditional, and if the backing device does not require stable writes, data may be modified without waiting. Fix these issues by making nilfs_page_mkwrite() wait for writeback to finish regardless of the stable write requirement of the backing device.

patch "iio: accel: bma400: Fix a compilation problem" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: accel: bma400: Fix a compilation problem to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-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.

That was the whole reason to introduce IIO_DMA_MINALIGN in [1]. Do the same for st_sensors common buffer. While at it, moved the odr_lock before buffer_data as we definitely don't want any other data to share a cacheline with the buffer.
