scsi: target: Fix SELinux error when systemd-modules loads the target module

2024-04-06T01:37:54Z

If the systemd-modules service loads the target module, the credentials of that userspace process will be used to validate the access to the target db directory. SELinux will prevent it, reporting an error like the following: kernel: audit: type=1400 audit(1676301082.205:4): avc: denied { read } for pid=1020 comm="systemd-modules" name="target" dev="dm-3" ino=4657583 scontext=system_u:system_r:systemd_modules_load_t:s0 tcontext=system_u:object_r:targetd_etc_rw_t:s0 tclass=dir permissive=0 Fix the error by using the kernel credentials to access the db directory Signed-off-by: Maurizio Lombardi Link: https://lore.kernel.org/r/20240215143944.847184-2-mlombard@redhat.com Reviewed-by: Mike Christie Signed-off-by: Martin K.

Pull block handle updates from Christian Brauner: "Last cycle we changed opening of block devices, and opening a block device would return a bdev_handle. This allowed us to implement support for restricting and forbidding writes to mounted block devices. It was accompanied by converting and adding helpers to operate on bdev_handles instead of plain block devices. That was already a good step forward but ultimately it isn't necessary to have special purpose helpers for opening block devices internally that return a bdev_handle. Fundamentally, opening a block device internally should just be equivalent to opening files. So now all internal opens of block devices return files just as a userspace open would. Instead of introducing a separate indirection into bdev_open_by_*() via struct bdev_handle bdev_file_open_by_*() is made to just return a struct file. Opening and closing a block device just becomes equivalent to opening and closing a file. This all works well because internally we already have a pseudo fs for block devices and so opening block devices is simple. There's a few places where we needed to be careful such as during boot when the kernel is supposed to mount the rootfs directly without init doing it. Here we need to take care to ensure that we flush out any asynchronous file close. That's what we already do for opening, unpacking, and closing the initramfs. So nothing new here. The equivalence of opening and closing block devices to regular files is a win in and of itself. But it also has various other advantages. We can remove struct bdev_handle completely. Various low-level helpers are now private to the block layer. Other helpers were simply removable completely. A follow-up series that is already reviewed build on this and makes it possible to remove bdev->bd_inode and allows various clean ups of the buffer head code as well. All places where we stashed a bdev_handle now just stash a file and use simple accessors to get to the actual block device which was already the case for bdev_handle" * tag 'vfs-6.9.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (35 commits) block: remove bdev_handle completely block: don't rely on BLK_OPEN_RESTRICT_WRITES when yielding write access bdev: remove bdev pointer from struct bdev_handle bdev: make struct bdev_handle private to the block layer bdev: make bdev_{release, open_by_dev}() private to block layer bdev: remove bdev_open_by_path() reiserfs: port block device access to file ocfs2: port block device access to file nfs: port block device access to files jfs: port block device access to file f2fs: port block device access to files ext4: port block device access to file erofs: port device access to file btrfs: port device access to file bcachefs: port block device access to file target: port block device access to file s390: port block device access to file nvme: port block device access to file block2mtd: port device access to files bcache: port block device access to files ...

2024-02-15T19:44:07Z

As of commit 066ff571011d ("block: turn bio_kmalloc into a simple kmalloc wrapper"), a bio allocated by bio_kmalloc() must be freed by bio_uninit() and kfree(). That is not done properly for the error case, hitting WARN and NULL pointer dereference in bio_free().

scsi: target: Fix unmap setup during configuration

2024-02-13T01:42:00Z

This issue was found and also debugged by Carl Lei . If the device is not enabled, iblock/file will have not setup their se_device to bdev/file mappings. If a user tries to config the unmap settings at this time, we will then crash trying to access a NULL pointer where the bdev/file should be. This patch adds a check to make sure the device is configured before we try to call the configure_unmap callout.
