2021-07-01nbd: 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.

2021-07-01ubd: remove the code to register as the legacy IDE driverChristoph Hellwig1-94/+12
With the legacy IDE driver long deprecated, and modern userspace being much more flexible about dev_t assignments there is no reason to fake a registration as the legacy IDE driver in ubd. This registeration is a little problematic as it registers the same request_queue for multiple gendisks, so just remove it.

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

It produces "YYYY-mm-dd HH:MM:SS" instead of "YYYY-mm-ddTHH:MM:SS". - Correctly parse long row of numbers by sscanf() when using the field width. Add extensive sscanf() selftest. - Generalize re-entrant CPU lock that has already been used to serialize dump_stack() output. It is part of the ongoing printk rework. It will allow to remove the obsoleted printk_safe buffers and introduce atomic consoles. - Some code clean up and sparse warning fixes. * tag 'printk-for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk: fix cpu lock ordering lib/dump_stack: move cpu lock to printk.c printk: Remove trailing semicolon in macros random32: Fix implicit truncation warning in prandom_seed_state() lib: test_scanf: Remove pointless use of type_min() with unsigned types selftests: lib: Add wrapper script for test_scanf lib: test_scanf: Add tests for sscanf number conversion lib: vsprintf: Fix handling of number field widths in vsscanf lib: vsprintf: scanf: Negative number must have field width > 1 usb: host: xhci-tegra: Switch to use %ptTs nilfs2: Switch to use %ptTs kdb: Switch to use %ptTs lib/vsprintf: Allow to override ISO 8601 date and time separator
