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.
2015-04-17tmpfs: use a seperate lock to protect all_nodesJustus Winter
Previously, tmpfs used diskfs_node_refcnt_lock to serialize access to the all_nodes and some other related global state related to memory consumption. Use a separate lock to protect all_nodes, and atomic operations to access the state related to memory consumption. Adjust the reference counting accordingly. Every node in the all_nodes 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 all_nodes. * tmpfs/tmpfs.h (num_files, tmpfs_space_used): Use atomic operations for these variables. (adjust_used): Use atomic operations. (get_used): New convenience function to atomically retrieve tmpfs_space_used. * tmpfs/node.c (all_nodes_lock): New lock. (diskfs_alloc_node): Use a separate lock to protect all_nodes. Adjust the reference counting accordingly. (diskfs_free_node): Likewise. (diskfs_cached_lookup):Likewise. (diskfs_node_iterate): Likewise. (diskfs_node_norefs): Do not remove the node from all_nodes. This actually looks like a mistake, I do not know why they did that here as well as in diskfs_free_node. (diskfs_try_dropping_softrefs): Check whether someone reacquired a reference, and if so hold on to our light reference. (diskfs_grow): Use atomic operations. * tmpfs/tmpfs.c (diskfs_set_statfs): Likewise.

2014-11-09Deal with odd kernel behaviorSamuel Thibault
Some versions of gnumach actually take address as a mapping hint, and would fail if the hint is bogus. Make sure to pass 0 for those versions. * console/pager.c (user_pager_create): Make sure to set *user to 0 before calling vm_map. * libdiskfs/disk-pager.c (diskfs_start_disk_pager): Make sure to set *image to 0 before calling vm_map. * libpager/pager-memcpy.c (pager_memcpy): Set window to 0 before calling vm_map. * tmpfs/node.c (diskfs_get_filemap): Make sure to set np->dn->u.reg.memref to 0 before calling vm_map.
2014-05-31tmpfs: use a thread timeoutJustus Winter
There is no need to keep all the threads around, just the master thread. * tmpfs/tmpfs (diskfs_thread_function): Use a thread timeout.
2014-04-30tmpfs: improve diskfs_node_iterateJustus Winter
Currently, diskfs_node_iterate iterates twice over all nodes. The first time only to determine the number of nodes. Simply count them instead. * tmpfs/node.c (all_nodes_nr_items): New variable. (diskfs_free_node): Decrement all_nodes_nr_items. (diskfs_node_norefs): Likewise. (diskfs_cached_lookup): Increment all_nodes_nr_items. (diskfs_node_iterate): Fix type of sum_nodes, use all_nodes_nr_items.

2014-02-25tmpfs: set diskfs_disk_name to "none"Justus Winter
By default diskfs_disk_name is returned as the source of libdiskfs-based translators. Hurds fstab allows multiple entries with the mnt_fsname being "none". * tmpfs/tmpfs.c (diskfs_disk_name): Set to "none".
2013-10-08Revert "tmpfs: drop privileges in the tmpfs translator"Justus Winter
This reverts commit 7075bc11289355478659cd1610632a9299734afc. Dropping the unix privileges of the tmpfs translator causes problems with the passive translator startup. The function fshelp_fetch_root creates an auth handle containing the processes original UID and GID. But if the privileges were dropped before, this operation fails with EPERM. This commit also broke mkfifo(3), possibly for similar or related reasons. * tmpfs/tmpfs.c (main): Do not drop all privileges.
2013-09-16Handle notification on page evictionRichard Braun

2013-08-28tmpfs: drop privileges in the tmpfs translatorJustus Winter
* tmpfs/tmpfs.c (main): Drop privileges.
2013-06-29tmpfs: fix parsing of fsys_set_options requestsJustus Winter
Formerly setting the options using fsys_set_options did not work because runtime_argp.options was set to 0. This fixes "remounting" of tmpfs translators. * tmpfs/tmpfs.c (runtime_argp): Use options as option list.

2012-09-30tmpfs: add --sizePino Toscano
Add the possibility to specify the size with the --size parameter; this makes tmpfs more usable in fstab or Linuxish mount invocations, since the size in such cases is a mount -o option, which gets translated to a --foo translator argument. The old way (specifying the size as the first argument) is left there; although, if --size is passed then the first argument must be "tmpfs", as it is what is passed by fstab/mount. * tmpfs/tmpfs.c (OPT_SIZE): New macro. (options): Add the "size" option. (parse_opt): Use -1 to indicate when SIZE is not yet set. <OPT_SIZE>: Handle case. <ARGP_KEY_NO_ARGS>: Error out only when SIZE is not set. <ARGP_KEY_ARGS>: Error out when SIZE is set and the argument is not "tmpfs".

2010-08-27Revert "Fix tmpfs assertion"Samuel Thibault
As discussed up to http://lists.gnu.org/archive/html/bug-hurd/2010-06/msg00021.html this reverts commit 97c5690abeaa88767acf2ffbb55552e8278052c8 and removes the corresponding assertion. This is related to commit 2f7f90ce15cce79ef83a8d273e3a27b5b527c7d7 which changes how much st_size is increased. * tmpfs/tmpfs.h (tmpfs_dirent): Remove `padding' field. * tmpfs/dir.c (diskfs_get_directs): Remove assertion on the position of the `name' field of struct tmpfs_dirent compared to the position of the `d_name' field of struct dirent.

2010-08-27Keep a reference on objects to preserve their content.Samuel Thibault
Modify tmpfs to keep a reference (by mapping it into its own space) to each memory object created by the user, so they don't get inmediately terminated at the end of the current operation. * tmpfs/tmpfs.h (struct disknode): Add `memref' field. * tmpfs/node.c (diskfs_get_filemap): vm_map() the first page of the newly-allocated object, store in `memref' field. (diskfs_free_node) vm_deallocate the page pointed by `memref' field.
2010-01-11Fix tmpfs assertionSamuel Thibault
* tmpfs/tmpfs.h (tmpfs_dirent): Add padding field to push the name field after its position in struct dirent.
