2024-08-26ext2fs: Ignore translators bits when checking we have no Hurd extensionsSamuel Thibault
We don't actually want to write these anyway.
2024-08-26ext2fs: Fix masking out translators bitsSamuel Thibault
We need to mask out before shifting the bits.
2024-03-12ext2fs: support translators on non-hurd-created filesystemsSamuel Thibault
We are fine with only using xattr on filesystems that don't have the i_translator inode field.
2024-03-04ext2fs: Check that the filesystem supports xattr before reading itDamien Zammit
2023-08-08Homogeneize [gs]et_translator and get_dire[nc]ts into mach_msg_type_number_tSamuel Thibault
This makes netfs_[gs]et_translator use mach_msg_type_number_t like the RPC and diskfs. This also makes the fshelp_fetch_root_callback1_t for fshelp_fetch_root use mach_msg_type_number_t. This also makes procfs_get_translator and the get_translator proc method use mach_msg_type_number_t. This makes diskfs_get_directs use mach_msg_type_number_t like the dir_readdir RPC Also get rid of u_int. This notably fixes _diskfs_translator_callback1_fn's bogus cast of size_t *argz_len into (u_int *).

2022-01-23ext2fs: Take cares of indiannesEtienne Brateau
In ext2 data are stored in little endian to ensure portability. So enforce little endian when manipulating these bytes. Message-Id: <20220123041715.19402-8-etienne.brateau@gmail.com>
2021-08-11ext2fs: Fix block allocation on symlink->translator conversionSamuel Thibault
In diskfs_set_translator we need to truncate the existing node before allocating the block for the translator.
2021-08-11ext2fs: clear data when setting a translator on a symlinkv0.9.git20210811Samuel Thibault
e2fsck does not like seeing both blocks for the symlink and for the translation entry. This fixes the disappearance of /dev/urandom.
2019-11-24ext2fs: Fix fast symlinks created by linuxDamien Zammit
linux seems to allocate 8 blocks for any fast symlink. * ext2fs/inode.c (write_symlink): Do not assert that st_blocks is 0. (read_symlink): Return EINVAL when node->dn_stat.st_size >= MAX_INODE_SYMLINK, not when node->dn_stat.st_blocks != 0.
2017-08-05Use our own variant of 'assert' and 'assert_perror'.Justus Winter
Our variants print stack traces on failures. This will make locating errors much easier.
2017-01-08ext2fs: downgrade warnings about old translator records to debug messagesRichard Braun
ext2fs/inode.c (diskfs_set_translator): Replace call to ext2_warning with ext2_debug. (diskfs_get_translator): Likewise.
2017-01-06ext2fs: minor cleanupRichard Braun
Fix some typos, types, add a few checks against integer overflows. ext2fs/inode.c (diskfs_user_read_node): Initialize datalen to 0. (diskfs_set_translator): Fix typo. (diskfs_get_translator): Change datalen type to size_t. * ext2fs/xattr.c (xattr_entry_get): Change type of block parameter to void *. (xattr_entry_create): Guard against integer overflows. (xattr_entry_replace): Likewise. (ext2_set_xattr): Fix typo.
2017-01-06ext2fs: Require users to opt-in for xattr-based translator records.Justus Winter
* ext2fs/ext2fs.c (use_xattr_translator_records): New variable. (X_XATTR_TRANSLATOR_RECORDS): New macro. (options): New option '--x-xattr-translator-records'. (parse_opt): Handle new option. * ext2fs/ext2fs.h (use_xattr_translator_records): New declaration. * ext2fs/inode.c (diskfs_set_translator): Use new variable. (diskfs_get_translator): Likewise.
2017-01-06ext2fs: Do not read translator record on Linux filesystems.Justus Winter
* ext2fs/inode.c (diskfs_user_read_node): Do not read translator record on filesystems using Linux on-disk format. We pondered to use this to introduce the feature, implementing it merely for Linux filesystem.
2017-01-06ext2fs: Fix typo.Justus Winter
2017-01-06ext2fs: Use xattr to store passive translatorShengyu Zhang
* ext2fs/inode.c (diskfs_set_translator): Use xattr to store passive translator if xattr is supported by filesystem. (diskfs_get_translator): Read value of xattr key "gnu.translator" if it exists. (diskfs_user_read_node): Set translator flag on reading.
2016-04-26Fix supporting >4GiB files in ext2fsSamuel Thibault
* ext2fs/inode.c (diskfs_user_read_node): When sizeof(off_t) >= 8, add di->i_size_high as high-64bit part to st->st_size. Drop setting unused info->i_high_size. (write_node): When sizeof(off_t) >= 8, write high-64bit part of st->st_size to di->i_size_high. * ext2fs/ext2_fs_i.h (ext2_inode_info): Remove i_high_size field. * pfinet/linux-src/include/linux/ext2_fs_i.h (ext2_inode_info): Likewise.
2015-04-17libdiskfs: implement a node cacheJustus Winter
Previously, all users of libdiskfs implemented a node cache on their own. Move the node cache from ext2fs into libdiskfs. We preserve the previous API by marking all functions that we pull from ext2fs as weak, so that users like tmpfs can still implement their own node cache. * ext2fs/dir.c (diskfs_lookup_hard): Adjust accordingly. * ext2fs/ext2fs.c (main): Don't call `inode_init'. * ext2fs/ext2fs.h (struct disknode): Drop `hnext', `hprevp'. * ext2fs/inode.c: Move the node cache into diskfs. (diskfs_user_make_node): New function. (diskfs_try_dropping_softrefs): Rename to `diskfs_user_try_dropping_softrefs'. (read_node): Rename to `diskfs_user_read_node'. Also move a chunk of code dealing with generations from `diskfs_cached_lookup' here. * libdiskfs/Makefile (OTHERSRCS): Add `node-cache.c'. * libdiskfs/diskfs.h (struct node): Add `hnext', `hprevp'. Amend existing comments, add forward declarations. * libdiskfs/node-cache.c: New file.
2015-04-17ext2fs: use fat nodesJustus Winter
Use `diskfs_make_node_alloc' to allocate both the node and the disknode in a continuous chunk of memory. This increases locality and reduces the pressure on the memory allocator. * ext2fs/inode.c: Use `diskfs_node_disknode' to access the disknode. (diskfs_cached_lookup): Use `diskfs_make_node_alloc' to allocate the node. (diskfs_node_norefs): Only free `np'. * ext2fs/dir.c: Use `diskfs_node_disknode' to access the disknode. * ext2fs/ext2fs.h: Likewise. * ext2fs/getblk.c: Likewise. * ext2fs/ialloc.c: Likewise. * ext2fs/pager.c: Likewise. * ext2fs/truncate.c: Likewise.
2015-04-17libdiskfs: lock-less reference counting of nodesJustus Winter
* libdiskfs/diskfs.h (struct node): Use refcounts_t for reference counting. (diskfs_node_refcnt_lock): Remove. (diskfs_node_norefs,diskfs_drop_node): Change comments accordingly. * libdiskfs/init-init.c: Adjust accordingly. * libdiskfs/node-drop.c: Likewise. * libdiskfs/node-make.c: Likewise. * libdiskfs/node-nput.c: Likewise. * libdiskfs/node-nputl.c: Likewise. * libdiskfs/node-nref.c: Likewise. * libdiskfs/node-nrefl.c: Likewise. * libdiskfs/node-nrele.c: Likewise. * libdiskfs/node-nrelel.c: Likewise. * ext2fs/inode.c: Likewise. * fatfs/inode.c: Likewise. * isofs/inode.c: Likewise. * tmpfs/node.c: Likewise. * doc/hurd.texi: Likewise.
2015-04-11ext2fs: use a seperate lock to protect nodehashJustus Winter
Previously, ext2fs used diskfs_node_refcnt_lock to serialize access to the nodehash. Use a separate lock to protect nodehash. Adjust the reference counting accordingly. Every node in the nodehash carries a light reference. When we are asked to give up that light reference, we reacquire our lock momentarily to check whether someone else reacquired a reference through the nodehash. * ext2fs/inode.c (nodecache_lock): New lock. (diskfs_cached_lookup): Use a separate lock to protect nodehash. Adjust the reference counting accordingly. (ifind): Likewise. (diskfs_node_iterate): Likewise. (diskfs_node_norefs): Move the code removing the node from nodehash... (diskfs_try_dropping_softrefs): ... here, where we check whether someone reacquired a reference, and if so hold on to our light reference.
2014-12-10Replace `bcopy' with `memcpy' or `memmove' as appropriateJustus Winter
* ext2fs/inode.c: Replace `bcopy' with `memcpy' or `memmove' as appropriate. * ext2fs/pager.c: Likewise. * isofs/lookup.c: Likewise. * isofs/main.c: Likewise. * isofs/rr.c: Likewise. * libdiskfs/file-get-trans.c: Likewise. * libiohelp/return-buffer.c: Likewise. * libpager/pagemap.c: Likewise. * libpipe/pq.c: Likewise. * libpipe/pq.h: Likewise. * libstore/unzipstore.c: Likewise. * mach-defpager/default_pager.c: Likewise. * pfinet/ethernet.c: Likewise. * pfinet/tunnel.c: Likewise. * storeio/dev.c: Likewise.
2014-12-10ext2fs: tune the size of the inode cacheJustus Winter
The node cache uses a fixed number of buckets giving it a linear access complexity, although with a small constant factor. Paper over this issue by increasing the number of buckets. * ext2fs/inode.c (INOHSZ): Increase from 512 to 8192 entries.
2014-04-30ext2fs: improve diskfs_node_iterateJustus Winter
Currently, diskfs_node_iterate iterates twice over all nodes in the cache. The first time only to determine the number of nodes currently in the cache. Simply count them instead. * ext2fs/inode.c (nodehash_nr_items): New variable. (diskfs_cached_lookup): Increment nodehash_nr_items. (diskfs_node_norefs): Decrement nodehash_nr_items. (diskfs_node_iterate): Fix the type of num_nodes, use nodehash_nr_items.
2013-09-16Large store support for ext2fsRichard Braun
This is a revised version of the large store patch for ext2fs, written by Ognyan Kulev. It provides support for stores larger than 2 GiB. * ext2fs/balloc.c: Use the new disk_cache_block_ref and disk_cache_block_deref functions to access blocks from the disk cache. * ext2fs/ext2fs.c (main): Update initialization call to pokel_init, and call map_hypermetadata instead of get_hypermetadata. * ext2fs/ext2fs.h: Include <hurd/store.h> and <hurd/ihash.h>.

(record_indir_poke): Likewise. (sync_global_ptr): Remove block reference, and adjust call to pager_sync_some. (sync_global): Add debug call to print wait parameter. * ext2fs/getblk.c: Use the new disk_cache_block_ref and disk_cache_block_deref functions to access blocks from the disk cache. * ext2fs/hyper.c (get_hypermetadata): Read the superblock from the store now that it's not directly mapped in memory. Move the initialization of zeroblock here from ... (map_hypermetadata): ... here. Also, set the superblock pointer. (diskfs_set_hypermetadata): Add a reference to the superblock. (diskfs_readonly_changed): Update call to mprotect. * ext2fs/ialloc.c: Use the new disk_cache_block_ref, disk_cache_block_ref_ptr and disk_cache_block_deref functions to access blocks from the disk cache. * ext2fs/inode.c: Update calls that used the disk image to use the disk cache, and use the new reference handling functions where appropriate. * ext2fs/pager.c: Include <unistd.h> and "../libpager/priv.h". (disk_image): Remove global variable. (disk_pager_read_page): Update cache information. (disk_pager_write_page): Likewise. (disk_pager_notify_evict): New function. (pager_notify_evict): Call disk_pager_notify_evict appropriately. (disk_cache): New global variable. (disk_cache_size): Likewise. (disk_cache_blocks): Likewise. (disk_cache_bptr): Likewise.

2012-07-03Fix stack corruption in ext2fs serverRichard Braun
* ext2fs/inode.c (diskfs_node_iterate): allocate the temporary node table from the heap instead of the stack.
2007-12-112007-12-11 Thomas Schwinge <tschwinge@gnu.org>Thomas Schwinge
* inode.c (read_node, write_node): Suggest what needs to be done in the future w.r.t. ``struct stat'' changes.
2002-10-082002-10-08 Roland McGrath <roland@frob.com>Roland McGrath
* ext2fs.h (struct disknode): New member `info_i_translator'. * inode.c (diskfs_set_translator): Update NP->dn->info_i_translator. * ialloc.c (diskfs_alloc_node): Clear a nonzero translator block in the on-disk inode just as we do for data blocks.
2002-06-112002-06-08 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (diskfs_cached_lookup): Use ino_t for argument. * ialloc.c (diskfs_free_node): Use %Ld format for ino_t/off_t values. * pager.c (diskfs_grow, pager_unlock_page): Likewise. * inode.c (read_node): Likewise. * dir.c (diskfs_get_directs): Likewise.
2002-01-042002-01-03 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (write_node): Never clear i_translator here. That is only done by diskfs_set_translator.
2001-11-212001-11-21 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (read_node): Just always call getpid for the fsid value.
2001-08-172001-08-16 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (write_node): Leave i_size, i_blocks, i_translator unchanged when the inode has been deleted. Suggested by Marcus Brinkmann.
2001-08-102001-08-09 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (diskfs_get_translator): Fail with EFTYPE if the length field stored on disk is unreasonable. Don't crash on ENOMEM. Use memcpy instead of bcopy.
2001-08-102001-08-09 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (diskfs_get_translator): Fail with EFTYPE if the length field stored on disk is unreasonable. Don't crash on ENOMEM. Use memcpy instead of bcopy.
2001-06-09* inode.c (diskfs_set_statfs): If number of free blocks is lessMark Kettenis
than the number of reserved blocks, set the number of available blocks to 0.
2001-01-072000-12-21 Marcus Brinkmann <marcus@gnu.org>Marcus Brinkmann
* pager.c: Include <errno.h>. (create_disk_pager): Panic if malloc fails. Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>. * inode.c (diskfs_get_translator): If malloc fails, set err to ENOMEM. Initialize err with 0, and return it at the end of the function. Reported by Igor Khavkine <i_khavki@alcor.concordia.ca>.
2000-12-032000-12-02 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (write_all_disknodes): Call diskfs_set_node_times after pokel_sync, since it might delay a little. (write_node): Remove assert that dn_set_mtime et al are clear. It is ok if they are set in parallel, because the latter setting will be carried out eventually.
2000-10-022000-10-01 Roland McGrath <roland@frob.com>Roland McGrath
* inode.c (write_node): Use memcpy instead of a loop.
2000-02-052000-02-05 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* ext2_fs.h: Update from Linux 2.3.42 version (ext2_fs_i.h unchanged). * inode.c (check_high_bits): In accordance with Linux 2.3.42 behavior, permit 32-bit uids on non-hurd filesystems unless i_dtime is zero (which indicates an extra old Linux ext2 implementation I guess).
1999-08-231999-08-23 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* inode.c (read_node): Don't set INFO->i_version. Extract INFO->i_dir_acl value only for a directory; otherwise use zero and instead extract INFO->i_high_size. Fail with EFBIG if INFO->i_high_size is nonzero. * inode.c (write_node): Get i_flags from NP->dn->info instead of from the disk inode, so we can have modified the in-core version. * dir.c (diskfs_direnter_hard, diskfs_dirremove_hard, diskfs_dirrewrite_hard): Clear EXT2_BTREE_FL flag bit from DP->dn->info.i_flags after modifying the directory (this is what Linux 2.3.14 does). * inode.c (read_node): i_version -> i_generation * inode.c (write_node): Likewise. * balloc.c (ext2_new_block): Take new arg PREALLOC_GOAL. Use that instead of hard-coded 8 as maximum of blocks to preallocate. Also test that instead of PREALLOC_COUNT to decide whether to try any preallocation at all. * getblk.c (ext2_alloc_block): Pass new arg to ext2_new_block. Use EXT2_DEFAULT_PREALLOC_BLOCKS as default (replaces hard-coded 8); For a regular file, use SBLOCK->s_prealloc_blocks before default. For a directory, use SBLOCK->s_dir_prealloc_blocks if the EXT2_FEATURE_COMPAT_DIR_PREALLOC flag is set, otherwise zero. * inode.c (diskfs_set_translator): Pass new arg (zero).

* pager.c: Clamp the number of free pages we keep around to some reasonably small value. Patch from Mark Kettenis <kettenis@wins.uva.nl>. 1999-06-15 Thomas Bushnell, BSG <tb@mit.edu> * inode.c (diskfs_validate_flags_change): Invert sense of test wrt bits that haven't yet been defined. Reported by Kalle Olavi Niemitalo <tosi@ees2.oulu.fi>.
1998-12-271998-12-27 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* inode.c (diskfs_set_statfs): Remove __ from struct members. 1998-12-21 Mark Kettenis <kettenis@phys.uva.nl> * inode.c (diskfs_set_statfs): Fill in statfs members that are used to implement statvfs.
