2024-07-11fs/ntfs3: Use function file_inode to get inode from fileKonstantin Komarov
Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Minor ntfs_list_ea refactoringKonstantin Komarov
For easy internal debugging. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Check more cases when directory is corruptedKonstantin Komarov
Mark ntfs dirty in this case. Rename ntfs_filldir to ntfs_dir_emit. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Do copy_to_user out of run_lockKonstantin Komarov
In order not to call copy_to_user (from fiemap_fill_next_extent) we allocate memory in the kernel, fill it and copy it to user memory after up_read(run_lock). Reported-by: syzbot+36bb70085ef6edc2ebb9@syzkaller.appspotmail.com Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Keep runs for $MFT::$ATTR_DATA and $MFT::$ATTR_BITMAPKonstantin Komarov
We skip the run_truncate_head call also for $MFT::$ATTR_BITMAP. Otherwise wnd_map()/run_lookup_entry will not find the disk position for the bitmap parts. Fixes: 0e5b044cbf3a ("fs/ntfs3: Refactoring attr_set_size to restore after errors") Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Missed error returnKonstantin Komarov
Fixes: 3f3b442b5ad2 ("fs/ntfs3: Add bitmap") Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Fix the format of the "nocase" mount optionKonstantin Komarov
The 'nocase' option was mistakenly added as fsparam_flag_no with the 'no' prefix, causing the case-insensitive mode to require the 'nonocase' option to be enabled. Fixes: a3a956c78efa ("fs/ntfs3: Add option "nocase"") Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26fs/ntfs3: Fix field-spanning write in INDEX_HDRKonstantin Komarov
Fields flags and res[3] replaced with one 4 byte flags. Fixes: 4534a70b7056 ("fs/ntfs3: Add headers and misc files") Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert attr_wof_frame_info() to use a folioMatthew Wilcox (Oracle)
This involves converting all users of offs_page to offs_folio, but it's worth it because we get rid of a lot of hidden calls to compound_head(). We continue to use order-0 folios here, and convert back to a struct page to call ntfs_bio_pages(). Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert ni_readpage_cmpr() to take a folioMatthew Wilcox (Oracle)
We still use an array of pages for the decompression, but this removes a few calls to compound_head(). Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert ntfs_get_frame_pages() to use a folioMatthew Wilcox (Oracle)
The function still takes an array of pages, but use a folio internally. This function would deadlock against itself if used with large folios (as it locks each page), so we can be a little sloppy with the conversion back from folio to page for now. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Remove calls to set/clear the error flagMatthew Wilcox (Oracle)
Nobody checks the error flag on ntfs3 folios, so stop setting and clearing it. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert attr_make_nonresident to use a folioMatthew Wilcox (Oracle)
Fetch a folio from the page cache instead of a page and operate on it. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> [almaz.alexandrovich@paragon-software.com: skip using folio_end_read] Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert attr_data_write_resident to use a folioMatthew Wilcox (Oracle)
Now that both callers of attr_data_write_resident() have a folio, pass it in and use memcpy_from_folio() to handle all the gnarly highmem multi-page problems. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert ntfs_write_end() to work on a folioMatthew Wilcox (Oracle)
Convert the passed page back into a folio and use the folio APIs, saving a few hidden calls to compound_head(). Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert attr_data_read_resident() to take a folioMatthew Wilcox (Oracle)
Now that all three callers have a folio, pass it in and use folio_fill_tail() to do the hard work of filling the folio. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert ntfs_write_begin to use a folioMatthew Wilcox (Oracle)
Retrieve a folio from the page cache instead of a precise page. This function is now large folio safe, but its called function is not. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-06-26ntfs3: Convert ntfs_read_folio to use a folioMatthew Wilcox (Oracle)
Remove the struct page conversion, and use a folio throughout. We still convert back to a struct page for calling some internal functions, but those will change soon. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

If the offset is equal to or greater than the end of file, an error is returned. For such operations (i.e., inserting a hole at the end of file), ftruncate(2) should be used. Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

2024-05-26Revert "perf parse-events: Prefer sysfs/JSON hardware events over legacy"Arnaldo Carvalho de Melo
This reverts commit 617824a7f0f73e4de325cf8add58e55b28c12493. This made a simple 'perf record -e cycles:pp make -j199' stop working on the Ampere ARM64 system Linus uses to test ARM64 kernels, as discussed at length in the threads in the Link tags below. The fix provided by Ian wasn't acceptable and work to fix this will take time we don't have at this point, so lets revert this and work on it on the next devel cycle.
