Raw Normal View History

General further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Additions to run checks on live filesystems. This change will not affect current systems until fsck is modified to use these new facilities. To try out this change, set the fsck passno to zero in /etc/fstab to cause the filesystem to be mounted without running fsck, then run `fsck_ffs -p -B <filesystem>' after the system has been brought up multiuser to run a background cleanup on <filesystem>.

This commit adds basic support for the UFS2 filesystem. The UFS2 filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage. Add the extent like functionality (framework is there, but is currently never used). Sponsored by: DARPA & NAI Labs. Reviewed by: Poul-Henning Kamp <phk@freebsd.org>

This fixes a problem with lost+found directories that was causing a segfault. Correctly initialize, static-ize, and remove global variables as needed in suj.c.

Rewrite the disk I/O management system in fsck_ffs(8). Other than making fsck_ffs(8) run faster, there should be no functional change. The original fsck_ffs(8) had its own disk I/O management system. When gjournal(8) was added to FreeBSD 7, code was added to fsck_ffs(8) to do the necessary gjournal rollback. Rather than use the existing fsck_ffs(8) disk I/O system, it wrote its own from scratch. Similarly when journalled soft updates were added in FreeBSD 9, code was added to fsck_ffs(8) to do the necessary journal rollback. And once again, rather than using either of the existing fsck_ffs(8) disk I/O systems, it wrote its own from scratch. Lastly the fsdb(8) utility uses the fsck_ffs(8) disk I/O management system. In preparation for making the changes necessary to enable snapshots to be taken when using journalled soft updates, it was necessary to have a single disk I/O system used by all the various subsystems in fsck_ffs(8). This commit merges the functionality required by all the different subsystems into a single disk I/O system that supports all of their needs. In so doing it picks up optimizations from each of them with the results that each of the subsystems does fewer reads and writes than it did with its own customized I/O system. It also greatly simplifies making changes to fsck_ffs(8) since everything goes through a single place. For example the ginode() function fetches an inode from the disk. When inode check hashes were added, they previously had to be checked in the code implementing inode fetch in each of the three different disk I/O systems. Now they need only be checked in ginode().

Update the actions previously attempted by the -D option to make them robust. With these changes fsck is now able to detect and reliably rebuild corrupted cylinder group maps. The -D option is no longer necessary as it has been replaced by a prompt asking whether the corrupted cylinder group should be rebuilt and doing so when requested. These actions are only offered and taken when running fsck in manual mode. Corrupted cylinder groups found during preen mode cause the fsck to fail. Add the -r option to free up excess unused inodes. Decreasing the number of preallocated inodes reduces the running time of future runs of fsck and frees up space that can allocated to files. The -r option is ignored when running in preen mode.

In fsck_ffs pass1, prevent the inosused variable from wrapping. The loop that scans the used inode map when soft updates is in use assumes that the inosused variable is signed.

Rewrite the disk I/O management system in fsck_ffs(8). Other than making fsck_ffs(8) run faster, there should be no functional change. The original fsck_ffs(8) had its own disk I/O management system. When gjournal(8) was added to FreeBSD 7, code was added to fsck_ffs(8) to do the necessary gjournal rollback. Rather than use the existing fsck_ffs(8) disk I/O system, it wrote its own from scratch. Similarly when journalled soft updates were added in FreeBSD 9, code was added to fsck_ffs(8) to do the necessary journal rollback. And once again, rather than using either of the existing fsck_ffs(8) disk I/O systems, it wrote its own from scratch. Lastly the fsdb(8) utility uses the fsck_ffs(8) disk I/O management system. In preparation for making the changes necessary to enable snapshots to be taken when using journalled soft updates, it was necessary to have a single disk I/O system used by all the various subsystems in fsck_ffs(8). This commit merges the functionality required by all the different subsystems into a single disk I/O system that supports all of their needs. In so doing it picks up optimizations from each of them with the results that each of the subsystems does fewer reads and writes than it did with its own customized I/O system. It also greatly simplifies making changes to fsck_ffs(8) since everything goes through a single place. For example the ginode() function fetches an inode from the disk. When inode check hashes were added, they previously had to be checked in the code implementing inode fetch in each of the three different disk I/O systems. Now they need only be checked in ginode().

Update the actions previously attempted by the -D option to make them robust. With these changes fsck is now able to detect and reliably rebuild corrupted cylinder group maps. The -D option is no longer necessary as it has been replaced by a prompt asking whether the corrupted cylinder group should be rebuilt and doing so when requested. These actions are only offered and taken when running fsck in manual mode. Corrupted cylinder groups found during preen mode cause the fsck to fail. Add the -r option to free up excess unused inodes. Decreasing the number of preallocated inodes reduces the running time of future runs of fsck and frees up space that can allocated to files. The -r option is ignored when running in preen mode.

Rewrite the disk I/O management system in fsck_ffs(8). Other than making fsck_ffs(8) run faster, there should be no functional change. The original fsck_ffs(8) had its own disk I/O management system. When gjournal(8) was added to FreeBSD 7, code was added to fsck_ffs(8) to do the necessary gjournal rollback. Rather than use the existing fsck_ffs(8) disk I/O system, it wrote its own from scratch. Similarly when journalled soft updates were added in FreeBSD 9, code was added to fsck_ffs(8) to do the necessary journal rollback. And once again, rather than using either of the existing fsck_ffs(8) disk I/O systems, it wrote its own from scratch. Lastly the fsdb(8) utility uses the fsck_ffs(8) disk I/O management system. In preparation for making the changes necessary to enable snapshots to be taken when using journalled soft updates, it was necessary to have a single disk I/O system used by all the various subsystems in fsck_ffs(8). This commit merges the functionality required by all the different subsystems into a single disk I/O system that supports all of their needs. In so doing it picks up optimizations from each of them with the results that each of the subsystems does fewer reads and writes than it did with its own customized I/O system. It also greatly simplifies making changes to fsck_ffs(8) since everything goes through a single place. For example the ginode() function fetches an inode from the disk. When inode check hashes were added, they previously had to be checked in the code implementing inode fetch in each of the three different disk I/O systems. Now they need only be checked in ginode().

This commit adds basic support for the UFS2 filesystem. The UFS2 filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage.

Ensure that files with no allocated blocks are trimmed to zero length. UFS does not allow files to end with a hole; it requires that the last block of a file be allocated. As fsck_ffs(8) initially scans each allocated inode, it tracks the last allocated block in the inode. It then checks that the inode's size falls in the last allocated block. If the last allocated block falls before the size, a `file size beyond end of allocated file' warning is issued and the file is shortened to reference the last allocated block (to avoid having it reference a hole at its end). If the last allocated block falls after the size, a `partially truncated file' warning is issued and all blocks following the block referenced by the size are freed. Because of an incorrect unsigned comparison, this test was failing to handle files with no allocated blocks but non-zero size (which should have had their size reset to zero). Once that was fixed the test started incorrectly complaining about short symbolic links that place the link path in the inode rather than in a disk block. Because these symbolic links have a non-zero size, but no allocated blocks, fsck_ffs wanted to zero out their size. This patch has to detect and avoid changing the size of such symbolic links.

Update the actions previously attempted by the -D option to make them robust. With these changes fsck is now able to detect and reliably rebuild corrupted cylinder group maps. The -D option is no longer necessary as it has been replaced by a prompt asking whether the corrupted cylinder group should be rebuilt and doing so when requested. These actions are only offered and taken when running fsck in manual mode. Corrupted cylinder groups found during preen mode cause the fsck to fail. Add the -r option to free up excess unused inodes. Decreasing the number of preallocated inodes reduces the running time of future runs of fsck and frees up space that can allocated to files. The -r option is ignored when running in preen mode.

Fsck_ffs did not properly range-check the inode 'di_size' field, so it was possible for a filesystem marked clean by fsck_ffs to cause kernel crashes later when mounted. This could occur when fsck_ffs was used to repair a badly corrupted filesystem. As pointed out by bde, it is not sufficient to restrict di_size to just the superblock fs_maxfilesize limit. The use of 32-bit logical block numbers (both in fsck and the kernel) induces another file size limit which is usually lower than fs_maxfilesize. Also, the old 4.3BSD filesystem does not have fs_maxfilesize initialised. Following this change, fsck_ffs will enforce exactly the same file size limits as are used by the kernel.

/* This should match the file size limit in ffs_mountfs(). */
Remove the kernel file-size limit for UFS2, so that only the limit imposed by the filesystem structure itself remains. With 16k blocks, the maximum file size is now just over 128TB. For now, the UFS1 file size limit is left unchanged so as to remain consistent with RELENG_4, but it too could be removed in the future. Reviewed by: mckusick

This commit adds basic support for the UFS2 filesystem. The UFS2 filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage.

Rewrite the disk I/O management system in fsck_ffs(8). Other than making fsck_ffs(8) run faster, there should be no functional change. The original fsck_ffs(8) had its own disk I/O management system. When gjournal(8) was added to FreeBSD 7, code was added to fsck_ffs(8) to do the necessary gjournal rollback. Rather than use the existing fsck_ffs(8) disk I/O system, it wrote its own from scratch. Similarly when journalled soft updates were added in FreeBSD 9, code was added to fsck_ffs(8) to do the necessary journal rollback. And once again, rather than using either of the existing fsck_ffs(8) disk I/O systems, it wrote its own from scratch. Lastly the fsdb(8) utility uses the fsck_ffs(8) disk I/O management system. In preparation for making the changes necessary to enable snapshots to be taken when using journalled soft updates, it was necessary to have a single disk I/O system used by all the various subsystems in fsck_ffs(8). This commit merges the functionality required by all the different subsystems into a single disk I/O system that supports all of their needs. In so doing it picks up optimizations from each of them with the results that each of the subsystems does fewer reads and writes than it did with its own customized I/O system. It also greatly simplifies making changes to fsck_ffs(8) since everything goes through a single place. For example the ginode() function fetches an inode from the disk. When inode check hashes were added, they previously had to be checked in the code implementing inode fetch in each of the three different disk I/O systems. Now they need only be checked in ginode().

It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage.

Rewrite the disk I/O management system in fsck_ffs(8). Other than making fsck_ffs(8) run faster, there should be no functional change. The original fsck_ffs(8) had its own disk I/O management system. When gjournal(8) was added to FreeBSD 7, code was added to fsck_ffs(8) to do the necessary gjournal rollback. Rather than use the existing fsck_ffs(8) disk I/O system, it wrote its own from scratch. Similarly when journalled soft updates were added in FreeBSD 9, code was added to fsck_ffs(8) to do the necessary journal rollback. And once again, rather than using either of the existing fsck_ffs(8) disk I/O systems, it wrote its own from scratch. Lastly the fsdb(8) utility uses the fsck_ffs(8) disk I/O management system. In preparation for making the changes necessary to enable snapshots to be taken when using journalled soft updates, it was necessary to have a single disk I/O system used by all the various subsystems in fsck_ffs(8). This commit merges the functionality required by all the different subsystems into a single disk I/O system that supports all of their needs. In so doing it picks up optimizations from each of them with the results that each of the subsystems does fewer reads and writes than it did with its own customized I/O system. It also greatly simplifies making changes to fsck_ffs(8) since everything goes through a single place. For example the ginode() function fetches an inode from the disk. When inode check hashes were added, they previously had to be checked in the code implementing inode fetch in each of the three different disk I/O systems. Now they need only be checked in ginode().

Update the actions previously attempted by the -D option to make them robust. With these changes fsck is now able to detect and reliably rebuild corrupted cylinder group maps. The -D option is no longer necessary as it has been replaced by a prompt asking whether the corrupted cylinder group should be rebuilt and doing so when requested. These actions are only offered and taken when running fsck in manual mode. Corrupted cylinder groups found during preen mode cause the fsck to fail. Add the -r option to free up excess unused inodes. Decreasing the number of preallocated inodes reduces the running time of future runs of fsck and frees up space that can allocated to files. The -r option is ignored when running in preen mode.

After a crash, a file that extends into indirect blocks may end up shorter than its size resulting in a hole as its final block (which is a violation of the invarients of the UFS filesystem). Soft updates will always ensure that the file size is correct when writing inodes to disk for files that contain only direct block pointers. However soft updates does not roll back sizes for files with indirect blocks that it has set to unallocated because their contents have not yet been written to disk. Hence, the file can appear to have a hole at its end because the block pointer has been rolled back to zero when its inode was written to disk. Thus, fsck_ffs calculates the last allocated block in the file. For files that extend into indirect blocks, fsck_ffs checks for a size past the last allocated block of the file and if that is found, shortens the file to reference the last allocated block thus avoiding having it reference a hole at its end.

Ensure that files with no allocated blocks are trimmed to zero length. UFS does not allow files to end with a hole; it requires that the last block of a file be allocated. As fsck_ffs(8) initially scans each allocated inode, it tracks the last allocated block in the inode. It then checks that the inode's size falls in the last allocated block.

Because of an incorrect unsigned comparison, this test was failing to handle files with no allocated blocks but non-zero size (which should have had their size reset to zero). Once that was fixed the test started incorrectly complaining about short symbolic links that place the link path in the inode rather than in a disk block.

Rewrite the disk I/O management system in fsck_ffs(8). Other than making fsck_ffs(8) run faster, there should be no functional change. The original fsck_ffs(8) had its own disk I/O management system. When gjournal(8) was added to FreeBSD 7, code was added to fsck_ffs(8) to do the necessary gjournal rollback. Rather than use the existing fsck_ffs(8) disk I/O system, it wrote its own from scratch. Similarly when journalled soft updates were added in FreeBSD 9, code was added to fsck_ffs(8) to do the necessary journal rollback. And once again, rather than using either of the existing fsck_ffs(8) disk I/O systems, it wrote its own from scratch. Lastly the fsdb(8) utility uses the fsck_ffs(8) disk I/O management system. In preparation for making the changes necessary to enable snapshots to be taken when using journalled soft updates, it was necessary to have a single disk I/O system used by all the various subsystems in fsck_ffs(8). This commit merges the functionality required by all the different subsystems into a single disk I/O system that supports all of their needs. In so doing it picks up optimizations from each of them with the results that each of the subsystems does fewer reads and writes than it did with its own customized I/O system. It also greatly simplifies making changes to fsck_ffs(8) since everything goes through a single place. For example the ginode() function fetches an inode from the disk. When inode check hashes were added, they previously had to be checked in the code implementing inode fetch in each of the three different disk I/O systems. Now they need only be checked in ginode().

This commit adds basic support for the UFS2 filesystem. The UFS2 filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage.

Merge from Lite2. Note that Lite2 has it's own filesystem clean check skipping code that overrides ours sooner. One should be eliminated, but for now it works.

Add the -R option to allow fsck_ffs to restart itself when too many critical errors have been detected in a particular run. Clean up the global state variables so that a restart can happen correctly. Separate the global variables in fsck_ffs and fsdb to their own file. This fixes header sharing with fscd. Correctly initialize, static-ize, and remove global variables as needed in dir.c.

Followup to -r344552 in which fsck_ffs checks for a size past the last allocated block of the file and if that is found, shortens the file to reference the last allocated block thus avoiding having it reference a hole at its end. This update corrects an error where fsck_ffs miscalculated the last logical block of the file when the file contained a large hole.

After a crash, a file that extends into indirect blocks may end up shorter than its size resulting in a hole as its final block (which is a violation of the invarients of the UFS filesystem). Soft updates will always ensure that the file size is correct when writing inodes to disk for files that contain only direct block pointers. However soft updates does not roll back sizes for files with indirect blocks that it has set to unallocated because their contents have not yet been written to disk. Hence, the file can appear to have a hole at its end because the block pointer has been rolled back to zero when its inode was written to disk. Thus, fsck_ffs calculates the last allocated block in the file. For files that extend into indirect blocks, fsck_ffs checks for a size past the last allocated block of the file and if that is found, shortens the file to reference the last allocated block thus avoiding having it reference a hole at its end.
