2021-06-07scsi: core: Put .shost_dev in failure path if host state changes to RUNNINGMing Lei
scsi_host_dev_release() only frees dev_name when host state is SHOST_CREATED. After host state has changed to SHOST_RUNNING, scsi_host_dev_release() no longer cleans up. Fix this by doing a put_device(&shost->shost_dev) in the failure path when host state is SHOST_RUNNING. Move get_device(&shost->shost_gendev) before device_add(&shost->shost_dev) so that scsi_host_cls_release() can do a put on this reference.

2021-06-07scsi: core: Fix failure handling of scsi_add_host_with_dma()Ming Lei
When scsi_add_host_with_dma() returns failure, the caller will call scsi_host_put(shost) to release everything allocated for this host instance. Consequently we can't also free allocated stuff in scsi_add_host_with_dma(), otherwise we will end up with a double free. Strictly speaking, host resource allocations should have been done in scsi_host_alloc(). However, the allocations may need information which is not yet provided by the driver when that function is called. So leave the allocations where they are but rely on host device's release handler to free resources.

2021-06-07scsi: core: Fix error handling of scsi_host_alloc()Ming Lei
After device is initialized via device_initialize(), or its name is set via dev_set_name(), the device has to be freed via put_device(). Otherwise device name will be leaked because it is allocated dynamically in dev_set_name(). Fix the leak by replacing kfree() with put_device(). Since scsi_host_dev_release() properly handles IDA and kthread removal, remove special-casing these from the error handling as well.

2021-06-07libbpf: Fixes incorrect rx_ring_setup_doneKev Jackson
When calling xsk_socket__create_shared(), the logic at line 1097 marks a boolean flag true within the xsk_umem structure to track setup progress in order to support multiple calls to the function. However, instead of marking umem->tx_ring_setup_done, the code incorrectly sets umem->rx_ring_setup_done. This leads to improper behaviour when creating and destroying xsk and umem structures. Multiple calls to this function is documented as supported.

2021-06-07neighbour: allow NUD_NOARP entries to be forced GCedDavid Ahern
IFF_POINTOPOINT interfaces use NUD_NOARP entries for IPv6. It's possible to fill up the neighbour table with enough entries that it will overflow for valid connections after that. This behaviour is more prevalent after commit 58956317c8de ("neighbor: Improve garbage collection") is applied, as it prevents removal from entries that are not NUD_FAILED, unless they are more than 5s old.

2021-06-07mlxsw: reg: Spectrum-3: Enforce lowest max-shaper burst size of 11Petr Machata
A max-shaper is the HW component responsible for delaying egress traffic above a configured transmission rate. Burst size is the amount of traffic that is allowed to pass without accounting. The burst size value needs to be such that it can be expressed as 2^BS * 512 bits, where BS lies in a certain ASIC-dependent range. mlxsw enforces that this holds before attempting to configure the shaper. The assumption for Spectrum-3 was that the lower limit of BS would be 5, like for Spectrum-1. But as of now, the limit is still 11. Therefore fix the driver accordingly, so that incorrect values are rejected early with a proper message.

2021-06-07afs: Fix partial writeback of large files on fsync and closeMarc Dionne
In commit e87b03f5830e ("afs: Prepare for use of THPs"), the return value for afs_write_back_from_locked_page was changed from a number of pages to a length in bytes. The loop in afs_writepages_region uses the return value to compute the index that will be used to find dirty pages in the next iteration, but treats it as a number of pages and wrongly multiplies it by PAGE_SIZE. This gives a very large index value, potentially skipping any dirty data that was not covered in the first pass, which is limited to 256M. This causes fsync(), and indirectly close(), to only do a partial writeback of a large file's dirty data. The rest is eventually written back by background threads after dirty_expire_centisecs.

2021-06-07Revert "ACPI: sleep: Put the FACS table after using it"Zhang Rui
Commit 95722237cb2a ("ACPI: sleep: Put the FACS table after using it") puts the FACS table during initialization. But the hardware signature bits in the FACS table need to be accessed, after every hibernation, to compare with the original hardware signature. So there is no reason to release the FACS table mapping after initialization. This reverts commit 95722237cb2ae4f7b73471058cdb19e8f4057c93. An alternative solution is to use acpi_gbl_FACS variable instead, which is mapped by the ACPICA core and never released.

On sunxi boards that use HDMI output, HDMI device probe keeps being avoided indefinitely with these repeated messages in dmesg: platform 1ee0000.hdmi: probe deferral - supplier 1ef0000.hdmi-phy not ready There's a fwnode_link being created with fw_devlink=on between hdmi and hdmi-phy nodes, because both nodes have 'compatible' property set. Fw_devlink code assumes that nodes that have compatible property set will also have a device associated with them by some driver eventually. This is not the case with the current sun8i-hdmi driver.

commit 471fbbea7ff7 ("ext4: handle casefolding with encryption") is missing a few checks for the encryption key which are needed to support deleting enrypted casefolded files when the key is not present. This bug made it impossible to delete encrypted+casefolded directories without the encryption key, due to errors like: W : EXT4-fs warning (device vdc): __ext4fs_dirhash:270: inode #49202: comm Binder:378_4: Siphash requires key Repro steps in kvm-xfstests test appliance: mkfs.ext4 -F -E encoding=utf8 -O encrypt /dev/vdc mount /vdc mkdir /vdc/dir chattr +F /vdc/dir keyid=$(head -c 64 /dev/zero | xfs_io -c add_enckey /vdc | awk '{print $NF}') xfs_io -c "set_encpolicy $keyid" /vdc/dir for i in `seq 1 100`; do mkdir /vdc/dir/$i done xfs_io -c "rm_enckey $keyid" /vdc rm -rf /vdc/dir # fails with the bug Fixes: 471fbbea7ff7 ("ext4: handle casefolding with encryption") Signed-off-by: Daniel Rosenberg <drosen@google.com> Link: https://lore.kernel.org/r/20210522004132.2142563-1-drosen@google.com Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2021-06-06ext4: fix memory leak in ext4_fill_superAlexey Makhalov
Buffer head references must be released before calling kill_bdev(); otherwise the buffer head (and its page referenced by b_data) will not be freed by kill_bdev, and subsequently that bh will be leaked. If blocksizes differ, sb_set_blocksize() will kill current buffers and page cache by using kill_bdev(). And then super block will be reread again but using correct blocksize this time. sb_set_blocksize() didn't fully free superblock page and buffer head, and being busy, they were not freed and instead leaked. This can easily be reproduced by calling an infinite loop of: systemctl start <ext4_on_lvm>.mount, and systemctl stop <ext4_on_lvm>.mount ... since systemd creates a cgroup for each slice which it mounts, and the bh leak get amplified by a dying memory cgroup that also never gets freed, and memory consumption is much more easily noticed.

Fast commit recovery data on disk may not be aligned.

As a consequence of it, we also remove some macros that could resulted in unaligned accesses.

In the case where st->ch_map[GRTS_CH_PRESSURE] < GRTS_MAX_CHANNELS is false and also st->ch_map[GRTS_CH_Z1] < GRTS_MAX_CHANNELS is false the variable press is not initialized and contains garbage. In this situation st->pressure is also false, so we do not actually use press value, but it is impossible for the compiler to realize this, and it emits "uninitialized variable" warning. Fix this by initializing press to 0 and allows us to also remove an else clause that sets press to 0.
