* libdiskfs: Flush node to disk before removing it from the cacheSamuel Thibault2021-08-111-0/+4
| | | | | | libdiskfs' dosync goes through the cache to flush nodes to the disk. We thus have to flush a node to the disk before removing it from the cache in diskfs_try_dropping_softrefs.
* bootstrap: Fix passing proc server from FS to rumpdiskSamuel Thibault2021-08-111-22/+18
| | | | | libdiskfs was passing its own proc port, thus confusing the fsys_init call in rumpdisk.
* Call _hurd_libc_proc_init when availableSamuel Thibault2021-04-111-0/+3
| | | | | | | | | | | glibc 2.33 separated out _hurd_libc_proc_init from _hurd_init, so we have to additionally call it. * configure.ac (_hurd_libc_proc_init): Detect function. * libdiskfs/boot-start.c (diskfs_S_fsys_init): Call _hurd_libc_proc_init. * libmachdev/trivfs_server.c (trivfs_S_fsys_init): Call _hurd_libc_proc_init.
* libdiskfs: do not reuse pathbufSamuel Thibault2020-11-271-6/+2
| | | | | | | | | When deadling with multiple levels of symlinks, we really need double buffering between the current path and the symlink target, and thus cannot reuse pathbuf. * libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Always use alloca for pathbuf.
* libdiskfs: enable relatime by defaultSamuel Thibault2020-10-102-2/+2
| | | | | | | | | Like Linux does, to avoid writing inodes when just reading files already in the cache. * libdiskfs/init-init.c (_diskfs_relatime): Set to 1. * libdiskfs/opts-std-runtime.c (set_opts): Always _diskfs_relatime from h->relatime.
* libdiskfs: Make relatime also update atime when equal to mtime/ctimeSamuel Thibault2020-10-031-2/+2
| | | | | | | Some tests (such as glibc's tst-atime) require it for instance. * libdiskfs/node-times.c (atime_should_update): Also return 1 when atime is equal to mtime or ctime.
* libdiskfs: Add relatime supportRyan Jeffrey2020-09-3011-11/+90
| | | | | | | | | | | | | | | | | | | | | | | | * doc/hurd.texi (diskfs_set_node_atime): Document relatime behavior. * libdiskfs/diskfs.h (diskfs_set_node_atime): Likewise. * libdiskfs/init-init.c (_diskfs_relatime): Add variable. * libdiskfs/file-statfs.c (ST_RELATIME): Define if not defined already. (diskfs_S_file_statfs): Report ST_RELATIME when _diskfs_relatime is set. * libdiskfs/node-times.c (atime_should_update): New function. (diskfs_set_node_atime): Document relatime behavior. Call atime_should_update instead of reading _diskfs_noatime. * libdiskfs/opts-common.c (diskfs_common_options): Add --strictatime and -R/--relatime options. * libdiskfs/opts-std-runtime.c (struct parse_hook): Add relatime field. (set_opts): Set _diskfs_relatime from relatime field. (parse_opt): Parse -R option. * libdiskfs/opts-std-startup.c (parse_startup_opt): Parse -R option. * libdiskfs/priv.h (_diskfs_relatime): Declare variable.

* diskfs: Add RPC for fsys_init to bootstrap if presentDamien Zammit2020-07-311-0/+13

* diskfs: Don't deallocate if dotdot is null in fsys-getroot.cDamien Zammit2020-07-311-1/+2
| | | | Message-Id: <20200728100837.224336-2-damien@zamaudio.com>
* libdiskfs: Refactor fsys_startup invokation for bootstrappingDamien Zammit2020-07-281-20/+38
| | | | | | | When we will have a rump translator before the root filesystem translator, we will want to give to the former a control port on the latter. Message-Id: <20200726073721.202405-1-damien@zamaudio.com>

* libdiskfs: Add missing node lock around fshelp_rlock_drop_peropen callSamuel Thibault2020-06-011-4/+3
| | | | | fshelp_rlock_drop_peropen actually needs the node to be locked for proper waiting atomicity.
* libdiskfs: Drop spurious mutex acquisitionSamuel Thibault2020-06-011-2/+0
| | | | | | | | diskfs_make_peropen does not need node to be locked. Worse, it could try to lock it. * libdiskfs/file-reparent.c (diskfs_S_file_reparent): Do not lock node around diskfs_make_peropen.
* libdiskfs,libnetfs: add missing io_pathconf casesSamuel Thibault2020-05-281-0/+10
| | | | | | | | * libdiskfs/io-pathconf.c (diskfs_S_io_pathconf): For _PC_REC_MAX_XFER_SIZE, _PC_REC_INCR_XFER_SIZE, _PC_SYMLINK_MAX, return undefined. For _PC_2_SYMLINKS, return 1. For _PC_REC_MIN_XFER_SIZE, _PC_REC_XFER_ALIGN, _PC_ALLOC_SIZE_MIN, return page size. * libnetfs/io-pathconf.c (netfs_S_io_pathconf): Likewise.

* Revert "libdiskfs: Shutdown pagers on startup_dosync."Samuel Thibault2018-01-151-1/+33
| | | | | | | | | | | This reverts commit 89a49ec8b3a847f3b770cff6a4a80b98b94ad7bf. There was a typo in diskfs_shutdown (FSYS_GOAWAY_FORCE || FSYS_GOAWAY_RECURSE) which was making it FSYS_GOAWAY_NOWAIT, and thus not actually syncing if there happens to be clients (it was then returning EBUSY). Fixing this into FSYS_GOAWAY_FORCE | FSYS_GOAWAY_RECURSE then makes it wait for clients (and NOWAIT is not supported), and there are very often some left, thus not syncing either.

* libdiskfs: Shutdown pagers on startup_dosync.Justus Winter2017-09-121-33/+1
| | | | | | | | | * libdiskfs/init-startup.c (diskfs_S_startup_dosync): Simplify the code by just using 'diskfs_shutdown' with the force flag. This also shuts down pagers, which potentially affects other tasks, but getting rid of the pagers allows us to commit a clean and consistent state to the disk before shutting down. Crashing other tasks just before the system powers down seems like a small price to pay.
* Traverse translator hierarchies using the fsys protocol.Justus Winter2017-09-124-109/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we used the fs protocol to traverse the translator hierarchies. This, however, is conceptually flawed, because translators are bound to nodes, and a node can have zero or more links in the file system. Therefore, the previous method of returning a list of paths to the client and expecting them to be able to follow these to reach the child translators was always unreliable. Fix this by using the fsys protocol to traverse the hierarchy, and returning the control ports of all children. This is more robust, and also conceptually cleaner, because the fsys protocol is about translator linkage, hence this is the point to implement traversal. Also move the get source routine over. A per-node source really does not fit the reality of most translators, while a per-translator source makes sense in many cases. * hurd/fs.defs (file_get_children): Drop routine. (file_get_source): Likewise. * hurd/fsys.defs (fsys_get_children): New routine. (fsys_get_source): Likewise. * libdiskfs/Makefile (FSYSSRCS): Remove files, add files. * libdiskfs/file-get-children.c: Remove file. * libdiskfs/fsys-get-children.c: New file. * libdiskfs/file-get-source.c: Remove file. * libdiskfs/fsys-get-source.c: New file. * libfshelp/fshelp.h (fshelp_filter): Remove type.

(open_hook): Remove scary comment, it is not applicable anymore because we no longer dir_lookup child translators.
* libfshelp: Use node instead of name as key.Justus Winter2017-09-122-2/+2
| | | | | | | | | | | | | | | | | | | | | | Previously, libfshelp used the name of an translator as key in the hash table. This however is flawed, because a translator is bound to a node, and a node can have zero or more links in the file system. Use the nodes address (or rather, the address of the transbox embedded in the node) as key instead. * libfshelp/fshelp.h (fshelp_set_active_translator): Instead of the control port, hand the whole transbox to the function. * libfshelp/translator-list.c (struct translator): New field 'locp'. (hash): Hash pointer. (compare): Compare pointer. (translator_ihash): Use an location pointer. (fshelp_set_active_translator): Use the address of the transbox as key.
