* Do not cache the R/O proxySamuel Thibault2022-08-101-5/+1
| | | | | We cannot properly detect when to release the ro_proxy, so let's just not cache it.
* ext2fs: Return read-only memory objects when appropriateSergey Bugaev2022-08-101-34/+39

* Change a EIO by a ENOSPC in case where not enough spaceEtienne Brateau2022-01-231-1/+1
| | | | | | Return a ENOSPC to notify that not enough space is here after the xattr entry instead of returning an EIO. Message-Id: <20220123041715.19402-15-etienne.brateau@gmail.com>
* ext2fs: refactor add a method for dupplicated codeEtienne Brateau2022-01-231-8/+14

| | | | Message-Id: <20220123041715.19402-9-etienne.brateau@gmail.com>
* ext2fs: Take cares of indiannesEtienne Brateau2022-01-239-284/+311
| | | | | | 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>
* ext2fs: use macro to check flagsEtienne Brateau2022-01-231-11/+13

* move to ext2_fs.h a #defineEtienne Brateau2022-01-233-6/+4
| | | | | This makes all #define be grouped at the same place Message-Id: <20220123041715.19402-4-etienne.brateau@gmail.com>
* ext2fs: remove __KERNEL__Etienne Brateau2022-01-231-209/+38
| | | | | This makes the header more clear and btw it’s not anymore in the linux tree Message-Id: <20220123041715.19402-3-etienne.brateau@gmail.com>
* ext2fs: update ext2_fs.h headerEtienne Brateau2022-01-231-15/+89

* ext2fs Merge 2 headersEtienne Brateau2022-01-233-42/+22
| | | | | * ext2_fs_i.h: merge it into ext2_fs.h. This is also done in the linux tree Message-Id: <20220123041715.19402-1-etienne.brateau@gmail.com>
* ext2fs: fix invalid checkEtienne Brateau2022-01-181-2/+2
| | | | | | | log2_dev_block_per_fs_block is unsigned so it won’t never be less than 0 and the check is then always false. Instead check the two values directly before doing the substraction. Message-Id: <20220118211140.8837-1-etienne.brateau@gmail.com>
* ext2fs: Disable an expensive checkSamuel Thibault2021-08-121-0/+4
| | | | | | disk_cache_block_is_ref calls hurd_ihash_find which is very expensive, so better disable the checks from record_global_poke and record_indir_poke unless building a debugging version.
* ext2fs: clear inline dataSamuel Thibault2021-08-111-0/+13
| | | | | When truncating a node with inline data, it's safer to really frob the inline data, to make sure ext2fs does not wrongly interprete it as block numbers.
* ext2fs: Fix block allocation on symlink->translator conversionSamuel Thibault2021-08-111-18/+19
| | | | | In diskfs_set_translator we need to truncate the existing node before allocating the block for the translator.
* ext2fs: clear data when setting a translator on a symlinkSamuel Thibault2021-08-111-0/+18
| | | | | | | e2fsck does not like seeing both blocks for the symlink and for the translation entry. This fixes the disappearance of /dev/urandom.
* ext2fs: Fix getting filemap for forcing delayed copiesSamuel Thibault2021-08-101-1/+1
| | | | The delayed copy actually needs write access.
* ext2fs: Update to upstream Hurd-reserved xattr index for "gnu.*".Jan (janneke) Nieuwenhuizen2020-05-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3980bd3b406addb327d858aebd19e229ea340b9a This supports setting (and reading) of passive trasnlators from GNU/Linux, e.g. dd if=/dev/zero of=file bs=1k count=1000 losetup /dev/loop0 file mke2fs -t ext2 -o hurd -O ext_attr /dev/loop0 mount -t ext2 -o x-xattr-translator-records /dev/loop0 /mnt mkdir -p /mnt/servers/socket touch /mnt/servers/socket/1 setfattr --name=gnu.translator --value='"/hurd/pflocal\0"' /mnt/servers/socket/1 getfattr --name=gnu.translator /mnt/servers/socket/1 # file: 1 gnu.translator="/hurd/pflocal" * ext2fs/xattr.c (xattr_prefixes): For "gnu.*", use index for the Hurd (10).
