2022-04-01fs: Add semihosting filesystemSean Anderson
This adds a filesystem which is backed by the host's filesystem. It is modeled off of sandboxfs, which has very similar aims. Semihosting doesn't support listing directories (except with SYS_SYSTEM), so neither do we. it's possible to optimize a bit for the common case of reading a whole file by omitting a call to smh_seek, but this is left as a future optimization.

2022-01-18fs/btrfs: fix a bug that U-boot fs btrfs implementation doesn't handle ↵Qu Wenruo
NO_HOLE feature correctly [BUG] When passing a btrfs with NO_HOLE feature to U-boot, and if one file contains holes, then the hash of the file is not correct in U-boot: # mkfs.btrfs -f test.img # Since v5.15, mkfs defaults to NO_HOLES # mount test.img /mnt/btrfs # xfs_io -f -c "pwrite 0 4k" -c "pwrite 8k 4k" /mnt/btrfs/file # md5sum /mnt/btrfs/file 277f3840b275c74d01e979ea9d75ac19 /mnt/btrfs/file # umount /mnt/btrfs # ./u-boot => host bind 0 /home/adam/test.img => ls host 0 < > 12288 Mon Dec 27 05:35:23 2021 file => load host 0 0x1000000 file 12288 bytes read in 0 ms => md5sum 0x1000000 0x3000 md5 for 01000000 ... 01002fff ==> 855ffdbe4d0ccc5acab92e1b5330e4c1 The md5sum doesn't match at all. [CAUSE] In U-boot btrfs implementation, the function btrfs_read_file() has the following iteration for file extent iteration: /* Read the aligned part */ while (cur < aligned_end) { ret = lookup_data_extent(root, &path, ino, cur, &next_offset); if (ret < 0) goto out; if (ret > 0) { /* No next, direct exit */ if (!next_offset) { ret = 0; goto out; } } /* Read file extent */ But for NO_HOLES features, hole extents will not have any extent item for it. Thus if @cur is at a hole, lookup_data_extent() will just return >0, and update @next_offset. But we still believe there is some data to read for @cur for ret > 0 case, causing we read extent data from the next file extent. This means, what we do for above NO_HOLES btrfs is: - Read 4K data from disk to file offset [0, 4K) So far the data is still correct - Read 4K data from disk to file offset [4K, 8K) We didn't skip the 4K hole, but read the data at file offset [8K, 12K) into file offset [4K, 8K). This causes the checksum mismatch. [FIX] Add extra check to skip to the next non-hole range after lookup_data_extent(). Signed-off-by: Qu Wenruo <wqu@suse.com>

- Fix mtd erase with mtdpart (Marek Behún) - NXP fspi driver fixes (Kuldeep Singh)
2021-10-23mtd: Remove mtd_erase_callback() entirelyMarek Behún
The original purpose of mtd_erase_callback() in Linux at the time it was imported to U-Boot, was to inform the caller that erasing is done (since it was an asynchronous operation). All supplied callback methods in U-Boot do nothing, but the mtd_erase_callback() function was (until previous patch) grossly abused in U-Boot's mtdpart implementation for completely different purpose. Since we got rid of the abusement, remove the mtd_erase_callback() function and the .callback member from struct erase_info entirely, in order to avoid such problems in the future.

2021-09-01btrfs: Use default subvolume as filesystem rootMatwey V. Kornilov
BTRFS volume consists of a number of subvolumes which can be mounted separately from each other. The top-level subvolume always exists even if no subvolumes were created manually. A subvolume can be denoted as the default subvolume i.e. the subvolume which is mounted by default. The default "default subvolume" is the top-level one, but this is far from the common practices used in the wild. For instance, openSUSE provides an OS snapshot/rollback feature based on BTRFS. To achieve this, the actual OS root filesystem is located into a separate subvolume which is "default" but not "top-level". That means that the /boot/dtb/ directory is also located inside this default subvolume instead of top-level one. However, the existing btrfs u-boot driver always uses the top-level subvolume as the filesystem root. This behaviour 1) is inconsistent with mount /dev/sda1 /target command, which mount the default subvolume 2) leads to the issues when /boot/dtb cannot be found properly (see the reference). This patch uses the default subvolume as the filesystem root to overcome mentioned issues. Reference: https://bugzilla.suse.com/show_bug.cgi?id=1185656 Signed-off-by: Matwey V.

2021-08-04fs/squashfs: Fix some hardlinks reading the wrong inodeCampbell Suter
In SquashFS, the contents of a directory is stored by squashfs_directory_entry structures which contain the file's name, inode and position within the filesystem. The inode number is not stored directly; instead each directory has one or more headers which set a base inode number, and files store the offset from that to the file's inode number. In mksquashfs, each inode is allocated a number in the same order as they are written to the directory table; thus the offset from the header's base inode number to the file's inode number is usually positive. Hardlinks are simply stored with two directory entries referencing the same file. This means the second entry will thus have an inode number much lower than the surrounding files. Since the header's base inode number comes from the first entry that uses the header, this delta will usually be negative. Previously, U-Boot's squashfs_directory_entry.inode_offset field was declared as an unsigned value. Thus when a negative value was found, it would either resolve to an invalid inode number or to that of an unrelated file. A squashfs image to test this can be created like so: echo hi > sqfs_test_files/001-root-file mkdir sqfs_test_files/002-subdir touch sqfs_test_files/002-subdir/003-file ln sqfs_test_files/{001-root-file,002-subdir/004-link} mksquashfs sqfs_test_files/ test.sqfs -noappend Note that squashfs sorts the files ASCIIbetacally, so we can use the names to control the order they appear in. The ordering is important - the first reference to the file must have a lower inode number than the directory in which the second reference resides, and the second reference cannot be the first file in the directory. Listing this sample image in U-Boot results in: => sqfsls virtio 2 002-subdir 0 003-file Inode not found. 0 004-link Signed-off-by: Campbell Suter <campbell@snapit.group> Reviewed-by: Miquel Raynal <miquel.raynal@bootlin.com>

2021-06-09fs/squashfs: fix reading of fragmented filesJoao Marcos Costa
The fragmented files were not correctly read because of two issues: - The squashfs_file_info struct has a field named 'comp', which tells if the file's fragment is compressed or not. This field was always set to 'true' in sqfs_get_regfile_info and sqfs_get_lregfile_info. It should actually take sqfs_frag_lookup's return value. This patch addresses these two assignments. - In sqfs_read, the fragments (compressed or not) were copied to the output buffer through a for loop which was reading data at the wrong offset. Replace these loops by equivalent calls to memcpy, with the right parameters. I tested this patch by comparing the MD5 checksum of a few fragmented files with the respective md5sum output in sandbox, considering both compressed and uncompressed fragments.
