This will be used to integrate with "Restore Previous Versions" feature added in Windows 7 for folks who reexport ceph through SMB. - security xattrs for ceph (Zheng Yan). Only selinux is supported for now due to the limitations of ->dentry_init_security(). - support for MSG_ADDR2, FS_BTIME and FS_CHANGE_ATTR features (Jeff Layton). This is actually a single feature bit which was missing because of the filesystem pieces. With this in, the kernel client will finally be reported as "luminous" by "ceph features" -- it is still being reported as "jewel" even though all required Luminous features were implemented in 4.13. - stop NULL-terminating ceph vxattrs (Jeff Layton). The convention with xattrs is to not terminate and this was causing inconsistencies with ceph-fuse. - change filesystem time granularity from 1 us to 1 ns, again fixing an inconsistency with ceph-fuse (Luis Henriques).

2019-07-08ceph: fix end offset in truncate_inode_pages_range callLuis Henriques1-1/+1
Commit e450f4d1a5d6 ("ceph: pass inclusive lend parameter to filemap_write_and_wait_range()") fixed the end offset parameter used to call filemap_write_and_wait_range and invalidate_inode_pages2_range. Unfortunately it missed truncate_inode_pages_range, introducing a regression that is easily detected by xfstest generic/130. The problem is that when doing direct IO it is possible that an extra page is truncated from the page cache when the end offset is page aligned. This can cause data loss if that page hasn't been sync'ed to the OSDs. While there, change code to use PAGE_ALIGN macro instead.

2019-06-09vfs: allow copy_file_range to copy across devicesAmir Goldstein1-1/+3
We want to enable cross-filesystem copy_file_range functionality where possible, so push the "same superblock only" checks down to the individual filesystem callouts so they can make their own decisions about cross-superblock copy offload and fallack to generic_copy_file_range() for cross-superblock copy. [Amir] We do not call ->remap_file_range() in case the files are not on the same sb and do not call ->copy_file_range() in case the files do not belong to the same filesystem driver. This changes behavior of the copy_file_range(2) syscall, which will now allow cross filesystem in-kernel copy. CIFS already supports cross-superblock copy, between two shares to the same server. This functionality will now be available via the copy_file_range(2) syscall.

Now that we have generic_copy_file_range(), remove it as a fallback case when offloads fail. This puts the responsibility for executing fallbacks on the filesystems that implement ->copy_file_range and allows us to add operational validity checks to generic_copy_file_range(). Rework vfs_copy_file_range() to call a new do_copy_file_range() helper to execute the copying callout, and move calls to generic_file_copy_range() into filesystem methods where they currently return failures.

2018-10-24iov_iter: Separate type from direction and use accessor functionsDavid Howells1-3/+2
In the iov_iter struct, separate the iterator type from the iterator direction and use accessor functions to access them in most places. Convert a bunch of places to use switch-statements to access them rather then chains of bitwise-AND statements. This makes it easier to add further iterator types. Also, this can be more efficient as to implement a switch of small contiguous integers, the compiler can use ~50% fewer compare instructions than it has to use bitwise-and instructions. Further, cease passing the iterator type into the iterator setup function. The iterator function can set that itself. Only the direction is required.

2018-10-22ceph: new mount option to disable usage of copy-from opLuis Henriques1-0/+3
Add a new mount option 'nocopyfrom' that will prevent the usage of the RADOS 'copy-from' operation in cephfs. This could be useful, for example, for an administrator to temporarily mitigate any possible bugs in the 'copy-from' implementation. Currently, only copy_file_range uses this RADOS operation. Setting this mount option will result in this syscall reverting to the default VFS implementation, i.e. to perform the copies locally instead of doing remote object copies.

2018-10-22ceph: only allow punch hole mode in fallocateLuis Henriques1-36/+9
Current implementation of cephfs fallocate isn't correct as it doesn't really reserve the space in the cluster, which means that a subsequent call to a write may actually fail due to lack of space. In fact, it is currently possible to fallocate an amount space that is larger than the free space in the cluster. It has behaved this way since the initial commit ad7a60de882a ("ceph: punch hole support"). Since there's no easy solution to fix this at the moment, this patch simply removes support for all fallocate operations but FALLOC_FL_PUNCH_HOLE (which implies FALLOC_FL_KEEP_SIZE).

struct timespec is not y2038 safe. Transition vfs to use y2038 safe struct timespec64 instead. The change was made with the help of the following cocinelle script.

dio_get_pagev_size() and dio_get_pages_alloc() introduced in commit b5b98989dc7e ("ceph: combine as many iovec as possile into one OSD request") assume that the passed iov_iter is ITER_IOVEC. This isn't the case with splice where it ends up poking into the guts of ITER_BVEC or ITER_PIPE iterators, causing lockups and crashes easily reproduced with generic/095. Rather than trying to figure out gap alignment and stuff pages into a page vector, add a helper for going from iov_iter to a bio_vec array and make use of the new CEPH_OSD_DATA_TYPE_BVECS code.

Otherwise, if the size is limited by the cap instead of the stripe unit, ceph_osdc_new_request() would setup an extent op that is bigger than what dio_get_pages_alloc() would pin and add to the page vector, triggering asserts in the messenger.

This patch adds support for the max_files quota. It hooks into all the ceph functions that add new filesystem objects that need to be checked against the quota limits. When these limits are hit, -EDQUOT is returned. Note that we're not checking quotas on ceph_link(). ceph_link doesn't really create a new inode, and since the MDS doesn't update the directory statistics when a new (hard) link is created (only with symlinks), they are not accounted as a new file.

In current code, regular file and directory use same struct ceph_file_info to store fs specific data so the struct has to include some fields which are only used for directory (e.g., readdir related info), when having plenty of regular files, it will lead to memory waste. This patch introduces dedicated ceph_dir_file_info cache for readdir related thins. So that regular file does not include those unused fields anymore.

2018-01-29ceph: track read contexts in ceph_file_infoYan, Zheng1-2/+8
Previously ceph_read_iter() uses current->journal to pass context info to ceph_readpages(), so that ceph_readpages() can distinguish read(2) from readahead(2)/fadvise(2)/madvise(2). The problem is that page fault can happen when copying data to userspace memory. Page fault may call other filesystem's page_mkwrite() if the userspace memory is mapped to a file. The later filesystem may also want to use current->journal. The fix is define a on-stack data structure in ceph_read_iter(), add it to context list in ceph_file_info. ceph_readpages() searches the list, find if there is a context belongs to current thread.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+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.
