2021-07-01s390/dasd: Avoid field over-reading memcpy()Kees Cook2-3/+5
In preparation for FORTIFY_SOURCE performing compile-time and run-time field array bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. Add a wrapping structure to serve as the memcpy() source, so the compiler can do appropriate bounds checking, avoiding this future warning: In function '__fortify_memcpy', inlined from 'create_uid' at drivers/s390/block/dasd_eckd.c:749:2: ./include/linux/fortify-string.h:246:4: error: call to '__read_overflow2_field' declared with attribute error: detected read beyond size of field (2nd parameter) Signed-off-by: Kees Cook <[email protected]> Signed-off-by: Stefan Haberland <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jens Axboe <[email protected]>

If disk have been deleted, we should return fail for ioctl BLKPG_DEL_PARTITION. Otherwise, the directory /sys/class/block may remain invalid symlinks file. The race as following: blkdev_open del_gendisk disk->flags &= ~GENHD_FL_UP; blk_drop_partitions blkpg_ioctl bdev_add_partition add_partition device_add device_add_class_symlinks ioctl may add_partition after del_gendisk() have tried to delete partitions.

2021-06-30nvme: use return value from blk_execute_rq()Keith Busch4-18/+33
We don't have an nvme status to report if the driver's .queue_rq() returns an error without dispatching the requested nvme command. Check the return value from blk_execute_rq() for all passthrough commands so the caller may know their command was not successful. If the command is from the target passthrough interface and fails to dispatch, synthesize the response back to the host as a internal target error.

2021-06-30nbd: provide a way for userspace processes to identify device backendsPrasanna Kumar Kalever2-1/+60
Problem: On reconfigure of device, there is no way to defend if the backend storage is matching with the initial backend storage. Say, if an initial connect request for backend "pool1/image1" got mapped to /dev/nbd0 and the userspace process is terminated. A next reconfigure request within NBD_ATTR_DEAD_CONN_TIMEOUT is allowed to use /dev/nbd0 for a different backend "pool1/image2" For example, an operation like below could be dangerous: $ sudo rbd-nbd map --try-netlink rbd-pool/ext4-image /dev/nbd0 $ sudo blkid /dev/nbd0 /dev/nbd0: UUID="bfc444b4-64b1-418f-8b36-6e0d170cfc04" TYPE="ext4" $ sudo pkill -9 rbd-nbd $ sudo rbd-nbd attach --try-netlink --device /dev/nbd0 rbd-pool/xfs-image /dev/nbd0 $ sudo blkid /dev/nbd0 /dev/nbd0: UUID="d29bf343-6570-4069-a9ea-2fa156ced908" TYPE="xfs" Solution: Provide a way for userspace processes to keep some metadata to identify between the device and the backend, so that when a reconfigure request is made, we can compare and avoid such dangerous operations. With this solution, as part of the initial connect request, backend path can be stored in the sysfs per device config, so that on a reconfigure request it's easy to check if the backend path matches with the initial connect backend path. Please note, ioctl interface to nbd will not have these changes, as there won't be any reconfigure.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull openat2 fixes from Christian Brauner: - Remove the unused VALID_UPGRADE_FLAGS define we carried from an extension to openat2() that we haven't merged. Aleksa might be getting back to it at some point but just not right now. - openat2() used to accidently ignore unknown flag values in the upper 32 bits. The new openat2() syscall verifies that no unknown O-flag values are set and returns an error to userspace if they are while the older open syscalls like open() and openat() simply ignore unknown flag values: #define O_FLAG_CURRENTLY_INVALID (1 << 31) struct open_how how = { .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID, .resolve = 0, }; /* fails */ fd = openat2(-EBADF, "/dev/null", &how, sizeof(how)); /* succeeds */ fd = openat(-EBADF, "/dev/null", O_RDONLY | O_FLAG_CURRENTLY_INVALID); However, openat2() silently truncates the upper 32 bits meaning: #define O_FLAG_CURRENTLY_INVALID_LOWER32 (1 << 31) #define O_FLAG_CURRENTLY_INVALID_UPPER32 (1 << 40) struct open_how how_lowe32 = { .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_LOWER32, }; struct open_how how_upper32 = { .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_UPPER32, }; /* fails */ fd = openat2(-EBADF, "/dev/null", &how_lower32, sizeof(how_lower32)); /* succeeds */ fd = openat2(-EBADF, "/dev/null", &how_upper32, sizeof(how_upper32)); Fix this by preventing the immediate truncation in build_open_flags() and add a compile-time check to catch when we add flags in the upper 32 bit range. * tag 'fs.openat2.unknown_flags.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: test: add openat2() test for invalid upper 32 bit flag value open: don't silently ignore unknown O-flags in openat2() fcntl: remove unused VALID_UPGRADE_FLAGS
