* libdiskfs: catch mmap failureSamuel Thibault2025-01-112-2/+5
| | | | Just backtrace for now
* ext2fs: Ignore translators bits when checking we have no Hurd extensionsSamuel Thibault2024-08-261-1/+1
| | | | We don't actually want to write these anyway.
* ext2fs: Fix masking out translators bitsSamuel Thibault2024-08-261-1/+1
| | | | We need to mask out before shifting the bits.
* ext2fs: mention which inode size is supportedSamuel Thibault2024-08-261-1/+1
|
* ext2fs: support translators on non-hurd-created filesystemsSamuel Thibault2024-03-121-36/+44
| | | | | We are fine with only using xattr on filesystems that don't have the i_translator inode field.
* ext2fs: New default: use xattrs to store translator recordsDamien Zammit2024-03-051-9/+9
| | | | | | | | | | Replaces experimental option --x-xattr-translator-records with --no-xattr-translator-records to allow rolling back to previous behaviour. NB: - Legacy records still work with either setting. - Adding a new record removes a legacy one.
* ext2fs: Check that the filesystem supports xattr before reading itDamien Zammit2024-03-041-10/+15

* Initialize a few error variables to avoid GCC warningsFlavio Cruz2023-12-291-1/+1
| | | | Message-ID: <20231229212105.858759-1-flaviocruz@gmail.com>
* Update server handlers to return kern_return_error to fix ↵Flavio Cruz2023-12-171-1/+1
| | | | | | | -Werror=enum-int-mismatch warnings MiG expects those to return kern_return_t. Message-ID: <ZXqbbXpVqQAwd2qv@jupiter.tail36e24.ts.net>
* ext2fs: Fix shift in find_next_zero_bitSamuel Thibault2023-08-081-1/+2
| | | | Shifting unsigned 32bit right by 32 bits is undefined, so avoid this.
* ext2fs: Fix shift in ext2_new_blockSamuel Thibault2023-08-081-2/+2
| | | | | Shifting signed integers left by 31 bits is not representable, so better make sure to use unsigned integers.
* Homogeneize [gs]et_translator and get_dire[nc]ts into mach_msg_type_number_tSamuel Thibault2023-08-082-3/+3
| | | | | | | | | | | | | | | | | 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 *).
* ext2fs: Fix unsigned long / uint32_t confusionSamuel Thibault2023-05-274-10/+10

* ext2fs: Port to x86_64Sergey Bugaev2023-05-106-14/+23

* Further modernize Hurd code by enforcing strict prototypes and no implicit ↵Flavio Cruz2023-04-081-3/+3
| | | | | | | | | | | | | | | | | | function declarations. Most of the changes land in one of these buckets: * Removed unused declarations. * Used (void) to represent no parameters instead of () which means an undeterminate number of parameters. * Included missing header files whenever necessary (stdlib.h, sys/mman.h, etc) * Typedefed function pointers to be able to fully declare the parameter types. * Added declarations of library functions that are used elsewhere (example is libps/ps.h). * Made functions static whenever they are only used in that file. * Forwarded declarations of some methods that were made static. Message-Id: <ZDD1o7/tVYeZew+G@jupiter.tail36e24.ts.net>
* Modernize code by removing use of old style definitions.Flavio Cruz2023-04-035-14/+14
| | | | | Also add -Werror=old-style-definition to enforce new code. Message-Id: <ZBZ+8xf7GHy2RT/h@jupiter.tail36e24.ts.net>
* Avoid undefined-behaviorSamuel Thibault2023-02-021-3/+3
| | | | | 1 << 31 is undefined behavior, 1 needs to be made unsigned for << 31 to be defined behavior.
* ext2fs: use __alignof (struct dirent) instead of hardcoding 4Samuel Thibault2023-02-021-1/+1
|
* Fix some compiler warningsSvante Signell2023-01-193-4/+4
|
* Fix *printf specifier for user space mach ports.Flavio Cruz2022-12-062-2/+2
| | | | | mach_port_t are mach_port_name_t and thus require %u instead of %lu. Message-Id: <Y42RELMbulK4xaKM@reue>
* Replace vsprintf with vsnprintf in ext2fs/msg.cFlavio Cruz2022-11-091-3/+3
| | | | Message-Id: <Y2s/UPSCuGap3cv6@viriathus>
* 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

* 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
| | | | Message-Id: <20220123041715.19402-2-etienne.brateau@gmail.com>
* 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
