* udf: Drop freed bitmap / table supportJan Kara2018-09-071-6/+0
| | | | | | | | | | We don't support Free Space Table and Free Space Bitmap as specified by UDF standard for writing as we don't support erasing blocks before overwriting them. Just drop the handling of these structures as partition descriptor checking code already makes sure such filesystems can be mounted only read-only. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Prevent write-unsupported filesystem to be remounted read-writeJan Kara2018-09-071-0/+2
| | | | | | | | | | | | | | | There are certain filesystem features which we support for reading but not for writing. We properly refuse to mount such filesystems read-write however for some features (such as read-only partitions), we don't check for these features when remounting the filesystem from read-only to read-write. Thus such filesystems could be remounted read-write leading to strange behavior (most likely crashes). Fix the problem by marking in superblock whether the filesystem has some features that are supported in read-only mode and check this flag during remount. Signed-off-by: Jan Kara <jack@suse.cz>

* udf: Do not mark possibly inconsistent filesystems as closedJan Kara2018-03-021-0/+1
| | | | | | | | | | | | If logical volume integrity descriptor contains non-closed integrity type when mounting the volume, there are high chances that the volume is not consistent (device was detached before the filesystem was unmounted). Don't touch integrity type of such volume so that fsck can recognize it and check such filesystem.

* udf: Ignore [ug]id=ignore mount optionsJan Kara2018-02-271-8/+6
| | | | | | | | | | | | | Currently uid=ignore and gid=ignore make no sense without uid=<number> and gid=<number> respectively as they result in all files having invalid uid / gid which then doesn't allow even root to modify files and thus causes confusion. And since commit ca76d2d8031f "UDF: fix UID and GID mount option ignorance" (from over 10 years ago) uid=<number> overrides all uids on disk as uid=ignore does. So just silently ignore uid=ignore mount option. Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>
* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

* udf: Use correct partition reference number for metadataAlden Tondettar2016-05-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UDF/OSTA terminology is confusing. Partition Numbers (PNs) are arbitrary 16-bit values, one for each physical partition in the volume. Partition Reference Numbers (PRNs) are indices into the the Partition Map Table and do not necessarily equal the PN of the mapped partition. The current metadata code mistakenly uses the PN instead of the PRN when mapping metadata blocks to physical/sparable blocks. Windows-created UDF 2.5 discs for some reason use large, arbitrary PNs, resulting in mount failure and KASAN read warnings in udf_read_inode(). For example, a NetBSD UDF 2.5 partition might look like this: PRN PN Type --- -- ---- 0 0 Sparable 1 0 Metadata Since PRN == PN, we are fine. But Windows could gives us: PRN PN Type --- ---- ---- 0 8192 Sparable 1 8192 Metadata So udf_read_inode() will start out by checking the partition length in sbi->s_partmaps[8192], which is obviously out of bounds. Fix this by creating a new field (s_phys_partition_ref) in struct udf_meta_data, referencing whatever physical or sparable map has the same partition number as the metadata partition.

* udf: Fix bitmap overflow on large filesystems with small block sizeJan Kara2013-02-051-1/+1
| | | | | | | | | | | | | | For large UDF filesystems with 512-byte blocks the number of necessary bitmap blocks is larger than 2^16 so s_nr_groups in udf_bitmap overflows (the number will overflow for filesystems larger than 128 GB with 512-byte blocks). That results in ENOSPC errors despite the filesystem has plenty of free space. Fix the problem by changing s_nr_groups' type to 'int'. That is enough even for filesystems 2^32 blocks (UDF maximum) and 512-byte blocksize. Reported-and-tested-by: v10lator@myway.de Signed-off-by: Jan Kara <jack@suse.cz>

* udf: Don't write integrity descriptor too oftenJan Kara2009-04-021-0/+2
| | | | | | | | | | | | | | | | We update information in logical volume integrity descriptor after each allocation (as LVID contains free space, number of directories and files on disk etc.). If the filesystem is on some phase change media, this leads to its quick degradation as such media is able to handle only 10000 overwrites or so. We solve the problem by writing new information into LVID only on umount, remount-ro and sync. This solves the problem at the price of longer media inconsistency (previously media became consistent after pdflush flushed dirty LVID buffer) but that should be acceptable.

* udf: Try anchor in block 256 firstJan Kara2009-04-021-1/+1
| | | | | | | | | | | | Anchor block can be located at several places on the medium. Two of the locations are relative to media end which is problematic to detect. Also some drives report some block as last but are not able to read it or any block nearby before it. So let's first try block 256 and if it is all fine, don't look at other possible locations of anchor blocks to avoid IO errors. This change required a larger reorganization of code but the new code is hopefully more readable and definitely shorter. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: use hardware sector sizeClemens Ladisch2009-04-021-0/+1
| | | | | | | | | | | | | | | | | | | This patch makes the UDF FS driver use the hardware sector size as the default logical block size, which is required by the UDF specifications. While the previous default of 2048 bytes was correct for optical disks, it was not for hard disks or USB storage devices, and made it impossible to use such a device with the default mount options. (The Linux mkudffs tool uses a default block size of 2048 bytes even on devices with smaller hardware sectors, so this bug is unlikely to be noticed unless UDF-formatted USB storage devices are exchanged with other OSs.) To avoid regressions for people who use loopback optical disk images or who used the (sometimes wrong) defaults of mkudffs, we also try with a block size of 2048 bytes if no anchor was found with the hardware sector size.

* udf: Cleanup anchor block detection.Jan Kara2008-04-171-1/+1
| | | | | | | | | | | | | | UDF anchor block detection is complicated by several things - there are several places where the anchor point can be, some of them relative to the last recorded block which some devices report wrongly. Moreover some devices on some media seem to have 7 spare blocks sectors for every 32 blocks (at least as far as I understand the old code) so we have to count also with that possibility. This patch splits anchor block detection into several functions so that it is clearer what we actually try to do. We fix several bugs of the type "for such and such media, we fail to check block blah" as a result of the cleanup. Signed-off-by: Jan Kara <jack@suse.cz>

| | | | | | | | | | | | | | | | | | | | Fix a bug in udf where it would write uid/gid = 0 to the disk for files owned by the id given with the uid=/gid= mount options. It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
