* Fix supporting >4GiB files in ext2fsSamuel Thibault2016-04-261-1/+0
| | | | | | | | | | * ext2fs/inode.c (diskfs_user_read_node): When sizeof(off_t) >= 8, add di->i_size_high as high-64bit part to st->st_size. Drop setting unused info->i_high_size. (write_node): When sizeof(off_t) >= 8, write high-64bit part of st->st_size to di->i_size_high. * ext2fs/ext2_fs_i.h (ext2_inode_info): Remove i_high_size field. * pfinet/linux-src/include/linux/ext2_fs_i.h (ext2_inode_info): Likewise.
* Fix gcc signedness warningsSamuel Thibault2016-01-141-1/+1
| | | | | * pfinet/linux-src/include/linux/skbuff.h (__skb_pull): Return unsigned char * instead of char *.
* Fix pfinet crashSamuel Thibault2016-01-031-0/+3
| | | | | | | | | | During rsyslog testsuite, it does happen that threads running schedule_timeout get woken up by something else than the timer. The (local) timer needs to be removed in that case. Let's just always remove it, like Linux does. * pfinet/glue-include/linux/sched.h (schedule_timeout): Remove local timer before returning.
* Make private variables staticSamuel Thibault2016-01-031-2/+2
| | | | * pfinet/timer-emul.c (timers, timer_thread): Make variables static.
* allow pfinet to link using -O0Flavio Cruz2016-01-0244-255/+238
| | | | | This fixes a long list of undefined references when compiling with -O0 by using static instead of extern in header files.
* Drop OTHERLIBS and use LDLIBS exclusivelyFlavio Cruz2015-12-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When cross-compiling, OTHERLIBS magically turns -lpthread into the path to the host libpthread.so file, resulting in build issues. LDLIBS does not suffer from this problem and it seems that is already being used in other Makefiles. This patch removes OTHERLIBS entirely from the build system. * Makeconf: Remove references to OTHERLIBS * auth/Makefile: Replace OTHERLIBS with LDLIBS. * boot/Makefile: Likewise. * console/Makefile: Likewise. * exec/Makefile: Likewise. * ext2fs/Makefile: Likewise. * fatfs/Makefile: Likewise. * ftpfs/Makefile: Likewise. * hostmux/Makefile: Likewise. * isofs/Makefile: Likewise. * libhurd-slab/Makefile: Likewise. * nfs/Makefile: Likewise. * nfsd/Makefile: Likewise. * pfinet/Makefile: Likewise. * proc/Makefile: Likewise. * procfs/Makefile: Likewise. * random/Makefile: Likewise. * storeio/Makefile: Likewise. * term/Makefile: Likewise. * tmpfs/Makefile: Likewise. * usermux/Makefile: Likewise.

| | | | * pfinet/main.c (main): Properly iterate over `pfinet_protid_portclasses'.
* pfinet: convert to trivfs dynamic classes and bucketsJustus Winter2015-09-274-37/+41
| | | | | | | | | | | | | | | | | | | | libtrivfs contains two ways of managing more than one port class and bucket. There is the old way of using a statically allocated array with explicit length, and the new way with dynamically allocated vectors. Converting all users to the new way of handling multiple classes and/or buckets, we can simplify the code in libtrivfs. In many cases, the code will be simpler and more expressive for the user. This also fixes a mild bug. The classes and buckets given to `trivfs_startup' end up in the dynamic vectors too, making the object lookup code use the more complicated code path. * pfinet/main.c: Convert to dynamic classes and buckets. * pfinet/options.c: Likewise. * pfinet/pfinet.h: Likewise. * pfinet/socket-ops.c: Likewise.
* Do not keep mutex locked while waiting for authenticate loopSamuel Thibault2015-07-041-0/+3

* Allow dhcp trafic and configurationSamuel Thibault2015-02-022-80/+258
| | | | | | | | | | | | | | | | | | | | | | | | | 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'.
* Remove unimplemented -s optionSamuel Thibault2015-02-021-1/+0
| | | | * pfinet/options.c (options): Remove 's' case.
* Backport Linux changes for proper TCP EOF handlingSamuel Thibault2015-01-033-32/+31
| | | | | | | | | | | | | 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.

* startup: bind the startup server to /servers/startupJustus Winter2014-11-211-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, the Hurd (ab)used the fact that the startup server speaks all protocols on its message port. Any server that wished to register for shutdown notifications would use proc_getmsgport to get a port to the startup server. This hardcodes the PID of /hurd/startup, and does not allow one to point a server to ones own startup server (e.g. using remap). Bind the startup server to /servers/startup instead. Use this to contact the startup server. * exec/main.c (S_exec_init): Use /servers/startup. Fall back to the old method so that the system still boots when the node /servers/startup is missing. * hurd/paths.h (_SERVERS_STARTUP): New macro. * libdiskfs/boot-start.c (diskfs_S_fsys_init): Use /servers/startup. * libdiskfs/init-startup.c (_diskfs_init_completed): Likewise. * pfinet/main.c (arrange_shutdown_notification): Likewise. * startup/Makefile (OBJS): Add fsysServer.o. * startup/startup.c (demuxer): Handle the fsys protocol.

The problem occurs because the timeout is implemented at the client side. For a non-blocking call, this means that (depending on the code path taken in the C library) the client could get a timeout without a full RPC round-trip to the server. Moving the implementation of the timeout to the servers guarantees a full round-trip, and correct results for non-blocking calls. The modifications in this change depend on the availability of the recently added pthread_hurd_cond_timedwait_np function in libpthread. * boot/boot.c (io_select_common): New static function. (S_io_select): Use io_select_common. (S_io_select_timeout): New function which makes use of io_select_common. * console-client/kbd-repeat.c (repeater_select): Add a timeout parameter. * console-client/pc-mouse.c (repeater_select): Likewise. * console-client/trans.c (io_select_common): New static function.
