2024-03-04ext4: detect directories in ext4fs_exists()Heinrich Schuchardt
While fat_exists() reports directories and files as existing ext4fs_exists() only recognizes files. This lead to errors when using systemd-boot with an ext4 file-system. Change ext4fs_exists() to find any type of inode: files, directories, symbolic links. Fixes: a1596438a689 ("ext4fs ls load support") Signed-off-by: Heinrich Schuchardt <[email protected]>

2023-12-13Merge patch series "bootm: Refactoring to reduce reliance on CMDLINE (part A)"Tom Rini
To quote the author: It would be useful to be able to boot an OS when CONFIG_CMDLINE is disabled. This could allow reduced code size. Standard boot provides a way to handle programmatic boot, without scripts, so such a feature is possible. The main impediment is the inability to use the booting features of U-Boot without a command line. So the solution is to avoid passing command arguments and the like to code in boot/ A similar process has taken place with filesystems, for example, where we have (somewhat) separate Kconfig options for the filesystem commands and the filesystems themselves. This series starts the process of refactoring the bootm logic so that it can be called from standard boot without using the command line. Mostly it removes the use of argc, argv and cmdtbl from the internal logic. Some limited tidy-up is included, but this is kept to smaller patches, rather than trying to remove all #ifdefs etc. Some function comments are added, however. A simple programmatic boot is provided as a starting point. This work will likely take many series, so this is just the start. Size growth with this series for firefly-rk3288 (Thumb2) is: arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0 This should be removed by: https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11 but it is not included in this series as it is already large enough. No functional change is intended in this series. Changes in v3: - Add a panic if programmatic boot fails - Drop RFC tag Changes in v2: - Add new patch to adjust position of unmap_sysmem() in boot_get_kernel() - Add new patch to obtain command arguments - Fix 'boot_find_os' typo - Pass in the command name - Use the command table to provide the command name, instead of "bootm"

2023-11-28Merge patch series "fs: fat: calculate FAT type based on cluster count"Tom Rini
To quote the author: This series fixes an issue where the FAT type (FAT12, FAT16) is not correctly detected, e.g. when the BPB field BS_FilSysType contains the valid value "FAT ". This issue occures, for example, if a partition is formatted by swupdate using its diskformat handler. swupdate uses the FAT library from http://elm-chan.org/fsw/ff/ internally. See https://groups.google.com/g/swupdate/c/7Yc3NupjXx8 for a discussion in the swupdate mailing list. Please refer to the commit messages for more details. 1. Added bootsector checks Most tests from https://www.win.tue.nl/~aeb/linux/fs/fat/fat-2.html are added in the commit 'fs: fat: add bootsector validity check'. Only the tests VIII, IX and X are not implemented. I also checked the Linux kernel code (v6.6) and did not find any checks on 'vistart->fs_type'. This is the reason why is skipped them here. See section '2. Size comparisons' for the impact on the binary size. 2. Size comparisons I executed bloat-o-meter from the Linux kernel for an arm64 target (config xilinx_zynqmp_mini_emmc0_defconfig): Comparison of the binary spl/u-boot-spl between master (rev e17d174773e9ba9447596708e702b7382e47a6cf) and this patch series (including the added validity checks of the boot sector): add/remove: 0/0 grow/shrink: 1/1 up/down: 100/-12 (88) Function old new delta read_bootsectandvi 308 408 +100 fat_itr_root 444 432 -12 Total: Before=67977, After=68065, chg +0.13% When compare the size of the binary spl/u-boot-spl between master this series without the the validity checks of the boot sector: add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-24 (-24) Function old new delta read_bootsectandvi 308 296 -12 fat_itr_root 444 432 -12 Total: Before=67977, After=67953, chg -0.04% So the size of the spl on this arm64 target increases by 88 bytes for this series. When i remove the validity check the size decreases by 24 bytes.

2023-11-16fs: btrfs: fix reading when length specifiedSam Edwards
The btrfs read function limits the read length to ensure that it and the read offset do not together exceed the size of the file. However, this size was only being queried if the read length was passed a value of zero (meaning "whole file"), and the size is defaulted to 0 otherwise. This means the clamp will just zero out the length if one is specified, preventing reading of the file. Fix this by checking the file size unconditionally, and unifying the default length and clamping logic as a single range check instead. This bug was discovered when trying to boot Linux with initrd= via 'bootefi' from a btrfs partition. The EFI stub entered an infinite loop of zero-length reads while trying to read the initrd, and the boot process stalled indefinitely.

2023-10-17Revert "fs: ext4: check the minimal partition size to mount"Sean Anderson
This check breaks small partitions (under 1024 blocks) because part_length is in units of part.blksz and not bytes. Given the purpose of this function, we really want to make sure the partition is SUPERBLOCK_START + SUPERBLOCK_SIZE (2048) bytes so we can call ext4_read_superblock without error. The obvious solution is to convert callers from things like ext4fs_mount(part_info.size) to ext4fs_mount(part_info.size * part_info.blksz); However, I'm not really a fan of the bloat that would cause, especially since the error is now suppressed. I think the best course of action here is to just revert the patch. This reverts commit 9905cae65e03335aefcb1ebfab5b7ee62d89f64e.

2023-08-03fat: correct sign for deletion markHeinrich Schuchardt
The FAT file systems uses character '\xe5' to mark a deleted directory entry. If a file name starts with this character, it is substituted by '\x05' in the directory entry. While (signed char)'\xe5' is a negative number 0xe5 is a positive integer number. We therefore have define a constant DELETED_MARK which matches the signedness of the characters in the directory entry. Correct a comparison where we used the constant 0xe5 with the wrong sign.

btrfs_read_extent_reg correctly computed the extent offset in the BTRFS_COMPRESS_NONE case, but did not account for the 'offset - key.offset' part correctly in the compressed case, making the function read incorrect data. In the case I examined, the last 4k of a file was corrupted and contained data from a few blocks prior, e.g. reading a 10k file with a single extent: btrfs_file_read() -> btrfs_read_extent_reg (aligned part loop, until 8k) -> read_and_truncate_page -> btrfs_read_extent_reg (re-reads the last extent from 8k to the end, incorrectly reading the first 2k of data) This can be reproduced as follow: $ truncate -s 200M btr $ mount btr -o compress /mnt $ pat() { dd if=/dev/zero bs=1M count=$1 iflag=count_bytes status=none | tr '\0' "\\$2"; } $ { pat 4K 1; pat 4K 2; pat 2K 3; } > /mnt/file $ sync $ filefrag -v /mnt/file File size of /mnt/file is 10240 (3 blocks of 4096 bytes) ext: logical_offset: physical_offset: length: expected: flags: 0: 0.. 2: 3328.. 3330: 3: last,encoded,eof $ umount /mnt Then in u-boot: => load scsi 0 2000000 file 10240 bytes read in 3 ms (3.3 MiB/s) => md 2001ff0 02001ff0: 02020202 02020202 02020202 02020202 ................ 02002000: 01010101 01010101 01010101 01010101 ................ 02002010: 01010101 01010101 01010101 01010101 ................
