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: declare all inline functions as `extern inline'Justus Winter
* libdiskfs/diskfs.h (diskfs_node_disknode, diskfs_disknode_node): Declare functions as `extern inline' so that we can use them in other functions declared as `extern inline'.
2015-04-17libdiskfs: fix node initializationJustus Winter
* libdiskfs/node-make.c (init_node): Initialize flag `author_tracks_uid'.
2015-04-17libdiskfs: drop unused fields from struct nodeJustus Winter

2015-04-17libdiskfs: make struct node more compactJustus Winter
* libdiskfs/diskfs.h (struct node): Turn flags into a bit field.
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.
2015-04-17isofs: use a seperate lock to protect node_cacheJustus Winter
Previously, isofs used diskfs_node_refcnt_lock to serialize access to the node_cache. Use a separate lock to protect node_cache. Adjust the reference counting accordingly. Every node in the node_cache 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 node_cache. * isofs/inode.c (nodecache_lock): New lock. (inode_cache_find): Use a separate lock to protect node_cache. Adjust the reference counting accordingly. (diskfs_cached_lookup): Likewise. (load_inode): Likewise. (cache_inode): Update comment accordingly. (diskfs_node_iterate): Likewise. (diskfs_node_norefs): Move the code removing the node from node_cache... (diskfs_try_dropping_softrefs): ... here, where we check whether someone reacquired a reference, and if so hold on to our light reference.
2015-04-11fatfs: use a seperate lock to protect nodehashJustus Winter
Previously, fatfs 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. * fatfs/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.

2015-02-14TODO: drop obsolete itemJustus Winter
* TODO (libpager): Drop item trying to prevent thread storms. We dealt with that in a much nicer way. Nowadays we use a fixed number of threads in libpager.
2015-02-08startup: add more error handlingJustus Winter
* startup/startup.c (launch_core_servers): Add more error handling.
2015-02-02Explicit the keymap compatibility flagsSamuel Thibault
Since "default" is not provided any more by xkb * console-client/xkb/xkb-data/keymap/hurd: Replace "default" xkb_compatibility by "basic+mousekeys+accessx(basic)+misc+iso9995+level5+caps(caps_lock)" for all keymaps.
2015-02-02Allow dhcp trafic and configurationSamuel Thibault
2007-10-14 Christian Dietrich <stettberger@dokucode.de> * options.c (options): Marked -a, -g -m, -p, -A, -G OPTION_ARG_OPTIONAL. (parse_interface_copy_device): New function. (parse_opt): When selecting another interface with -i set the options from e.g. a prior fsysopts call as default values. For -a, -g, -p, -g, -A, -G set the optional argument as value. When there is no argument, delete the value (e.g. unset default gateway). Delete delete default gateways only if the set gateway is on an interface modified in this call. Add always an route for dhcp packages on all devices. By doing this we can send dhcp renew packages. (trivfs_append_args): Add --gateway only once. 2007-10-14 Marco Gerards <metgerards@student.han.nl> * options.c (parse_opt): Add the route for `0.0.0.0' so broadcasting works. * linux-src/net/ipv4/devinet.c (inet_insert_ifa) [_HURD_]: Don't fail when the address is `0.0.0.0'.

This fixes a deallocation of an invalid port notably seen on system shutdown. * console/display.c (free_modreqs): Handle errors of `mach_port_request_notification' and check whether the old notification port was valid. (do_mach_notify_msg_accepted): Likewise. (display_notice_filechange): Likewise.
2015-01-17proc: call `startup_essential_task' earlierJustus Winter
Previously, the proc server did not call `startup_essential_task' until it got the message port of the startup server using `proc_setmsgport'. Now that we have `/servers/startup', we can do this in main, before we start our message service loop. A complication arises because the traditional startup server is single-threaded. Handle this by tweaking startup not to bind itself to `/servers/startup' before it is ready. * proc/main.c (main): Try to lookup `/servers/startup' and send the message here, or... * proc/msg.c (S_proc_setmsgport): ... fall back to the old way here. * proc/proc.h (startup_fallback): New variable. * startup/startup.c (main): Move code installing ourself on `/servers/startup' (install_as_translator): ... here. (launch_core_servers): And use it here, just before we reply to `/hurd/auth'.
2015-01-17auth: remove implicit assumption about the bootstrap processJustus Winter
The current code assumes that it can speak the startup protocol over its bootstrap port. * auth/auth.c (main): Generalize by trying to use `/servers/startup' before falling back to the bootstrap port.
2015-01-17auth: simplify expressionJustus Winter
* auth/auth.c (S_auth_{user,server}_authenticate): Simplify expression.
2015-01-17startup: give the tasks we create a nameJustus Winter
* startup/startup.c (run): Name the tasks we start.
2015-01-17libports: silence pointless error messageJustus Winter
* libports/manage-multithread.c (adjust_priority): Silence pointless error message.
2015-01-17libdiskfs: fix port leakJustus Winter
* libdiskfs/boot-start.c (get_console): Deallocate `device_master'.
2015-01-17libfshelp: improve error handlingJustus Winter
* libfshelp/start-translator-long.c (fshelp_start_translator_long): Once we have a task, go to `lose_task' so that we do not leave hosed tasks around.
2015-01-04random: fix typoJustus Winter
* random/gnupg-random.c (read_pool): Fix typo in comment.
2015-01-03Backport Linux changes for proper TCP EOF handlingSamuel Thibault
Notably when remote eagerly sends a RST: we want to return EOF to the application, not EPIPE. * pfinet/linux-src/net/ipv4/tcp_output.c (tcp_connect): Set sk->done to 0. * pfinet/linux-src/net/ipv4/tcp_input.c (tcp_fin): Set RCV_SHUTDOWN, and sk->done to 1. * pfinet/linux-src/net/ipv4/tcp.c (tcp_recv_urg): Only return ENOTCONN when we never actually connect. Always return 0 when reception is closed. (tcp_recvmsg): When any data is available, ignore errors and EOF. When no data is available, first check for reception being closed, then for errors.
