This page describes a single unified set + of interdependent changes, but there are so many changes that I have + broken up the log entry into paragraphs based on rough topical + divisions of the work involved. + + Subset of verbatim Linux 2.2.12 sources imported on a vendor branch. + * linux-src: New directory, see README for details. + * README: New file, describes linux-src layout and procedures for + tracking Linux source updates. + + Light modifications to linux-src files to avoid really bending over + backwards with the glue macros. All modifications to files in + linux-src are conditionalized by #ifdef _HURD_. + * linux-src/include/linux/net.h [_HURD_] (struct socket): New members + refcnt and identity; elide members fasync_list, file. + * linux-src/include/linux/rtnetlink.h [! CONFIG_RTNETLINK] + (rtnl_shlock, rtnl_shunlock) [! _HURD_]: Conditionalize contents on + this, making these no-ops #ifdef _HURD_. + * linux-src/net/core/dev.c [_HURD_] (dev_ioctl): Don't define the + function, instead #define it to 0. + * linux-src/net/ipv4/af_inet.c [_HURD_] (inet_ioctl): Likewise. + * linux-src/net/ipv4/arp.c [_HURD_] (arp_ioctl): Likewise. + * linux-src/net/ipv4/udp.c [_HURD_] (udp_ioctl): Likewise. + * linux-src/net/ipv4/tcp.c [_HURD_] (tcp_ioctl): Likewise. + [_HURD_] (tcp_tiocinq): New function, TIOCINQ code from tcp_ioctl. + * linux-src/net/ipv4/devinet.c [_HURD_] (devinet_ioctl): Don't define + the function, instead #define it to 0. + [_HURD_] (configure_device): New function, cobbled from SIOCSIFADDR + and SIOCSIFNETMASK code from devinet_ioctl. + + * glue-include/asm, glue-include/linux: New directories. + These contain glue kludge headers that replace all of the + Linux <asm/*.h> headers except checksum.h, and several of + the Linux <linux/*.h> headers (the remainder come from + linux-src/include/linux and are mostly unmodified). + * glue-include/asm/atomic.h: New file, glue replacement header. + * glue-include/asm/bitops.h: New file, glue replacement header. + * glue-include/asm/byteorder.h: New file, glue replacement header. + * glue-include/asm/checksum.h: New file, glue replacement header. + * glue-include/asm/errno.h: New file, glue replacement header. + * glue-include/asm/hardirq.h: New file, glue replacement header. + * glue-include/asm/init.h: New file, glue replacement header. + * glue-include/asm/segment.h: New file, glue replacement header. + * glue-include/asm/spinlock.h: New file, glue replacement header. + * glue-include/asm/system.h: New file, glue replacement header. + * glue-include/asm/types.h: New file, glue replacement header. + * glue-include/asm/uaccess.h: New file, glue replacement header. + * glue-include/linux/autoconf.h: New file, glue replacement header. + * glue-include/linux/binfmts.h: New file, glue replacement header. + * glue-include/linux/config.h: New file, glue replacement header. + * glue-include/linux/errno.h: New file, glue replacement header. + * glue-include/linux/fcntl.h: New file, glue replacement header. + * glue-include/linux/fs.h: New file, glue replacement header. + * glue-include/linux/in.h: New file, glue replacement header. + * glue-include/linux/in6.h: New file, glue replacement header. + * glue-include/linux/interrupt.h: New file, glue replacement header. + * glue-include/linux/ioctl.h: New file, glue replacement header. + * glue-include/linux/ipv6.h: New file, glue replacement header. + * glue-include/linux/kernel.h: New file, glue replacement header. + * glue-include/linux/limits.h: New file, glue replacement header. + * glue-include/linux/major.h: New file, glue replacement header. + * glue-include/linux/malloc.h: New file, glue replacement header. + * glue-include/linux/mm.h: New file, glue replacement header. + * glue-include/linux/param.h: New file, glue replacement header. + * glue-include/linux/personality.h: New file, glue replacement header. + * glue-include/linux/poll.h: New file, glue replacement header. + * glue-include/linux/proc_fs.h: New file, glue replacement header. + * glue-include/linux/sched.h: New file, glue replacement header. + * glue-include/linux/slab.h: New file, glue replacement header. + * glue-include/linux/socket.h: New file, glue replacement header. + * glue-include/linux/sockios.h: New file, glue replacement header. + * glue-include/linux/stat.h: New file, glue replacement header. + * glue-include/linux/string.h: New file, glue replacement header. + * glue-include/linux/termios.h: New file, glue replacement header. + * glue-include/linux/time.h: New file, glue replacement header. + * glue-include/linux/timer.h: New file, glue replacement header. + * glue-include/linux/timex.h: New file, glue replacement header. + * glue-include/linux/types.h: New file, glue replacement header. + * glue-include/linux/un.h: New file, glue replacement header. + * glue-include/linux/version.h: New file, glue replacement header. + * glue-include/linux/wait.h: New file, glue replacement header. + + * kmem_cache.c: New file.

Add -I's for glue-include and linux-src/include. + + * pfinet.h: Include <sys/socket.h>, and not <linux/netdevice.h>. + (master_device): Remove decl. + (global_lock, packet_queue_lock): Remove common defns. + (global_lock, net_bh_lock): Declare them as externs. + (struct sockaddr): Remove len member, make address member just a + struct sockaddr rather than a 0-length array. + (setup_loopback_device, become_task_protid, become_task): Remove decls. + (ethernet_initialize): Declare it. + (input_work_thread): Remove decl. + (net_bh_thread): Declare it. + (tcp_readable): Remove decl. + (tcp_tiocinq): Declare it. + + * config.h: Rewritten based on Linux 2.2.12 set of CONFIG_* options. + (CONFIG_NET, CONFIG_INET, CONFIG_SKB_LARGE): These are the only + Linux config options we set. + (CONFIG_IP_NOSIOCRT): New macro (not a proper config option, but + used conveniently in the code). + * ethernet.c (ethernet_set_multi): Take only one parameter. + Remove assert, since we always get passed IGMP_ALL_HOSTS. + (ethernet_thread): Make static. + (ethernet_demuxer): Use __mutex_lock in place of mutex_lock, so as to + get cthreads instead of linux/spinlock.h glue macros. Lock + net_bh_lock instead of global_lock. Set SKB->protocol with + eth_type_trans before calling netif_rx. + (ethernet_initialize): New function, one-time initialization broken + out of ethernet_open. + (ethernet_open): Ports setup moved to ethernet_initialize. + Don't use `errno' to avoid glue conflicts. + Use get_privileged_ports here to get the master device port, and + deallocate it after calling device_open. + (ethernet_xmit): Use assert_perror. Only one arg to dev_kfree_skb now. + (setup_ethernet_device): Change initializations for structure changes. + Call dev_init_buffers and register_netdevice on the device. + * timer-emul.c (all functions): Use __mutex_lock instead of mutex_lock. + Adjust for renaming of `prevp' member to `prev' in struct timer_list. + (mod_timer): New function. + * socket.c (proto_ops): Variable removed. + (net_families): New variable replaces it. + (sock_register): Rewritten for new calling convention, set + net_families rather than proto_ops. + (make_sock_user, clean_socketport, sock_alloc, sock_release): + Functions moved here from misc.c. + * sched.c (packet_queue_lock): Variable removed. + (net_bh_lock, net_bh_wakeup): New variables. + (current): Variable removed (now a macro in the glue headers). + (interruptible_sleep_on, wake_up_interruptible): Functions removed. + They are replaced by inlines in the glue headers. + (become_task, become_task_protid): Functions removed; they are + replaced by macros in glue-include/linux/sched.h. + (net_bh_worker): New function. + * loopback.c: Completely rewritten, mostly copied from linux-2.2.12's + drivers/net/loopback.c source file. + + * io-ops.c (all functions): Use __mutex_lock in place of mutex_lock. + (S_io_write): Call ops->sendmsg instead of ops->write, + which no longer exists. If O_NONBLOCK is set, set MSG_DONTWAIT in + msg_flags. + (S_io_read): Call ops->recvmsg instead of ops->read, + which no longer exists If O_NONBLOCK is set, pass MSG_DONTWAIT. + (S_io_readable): Use USER->sock->data in place of USER->sock->sk. + For SOCK_STREAM and SOCK_SEQPACKET types, call tcp_tiocinq. + (S_io_set_all_openmodes, S_io_get_openmodes, S_io_set_some_openmodes, + S_io_clear_some_openmodes): Member USER->sock->userflags is now + renamed USER->sock->flags. + (S_io_select): Completely rewritten using ops->poll. + (select_wait): Function removed. + (S_io_stat): Set st_mode to reflect S_IFSOCK. + * socket-ops.c (all functions): Use __mutex_lock instead of mutex_lock. + (S_socket_create): Don't set SOCK->ops or call SOCK->ops->create. + Instead, call net_families[PF_INET]->create. + (S_socket_listen): Remove extra checks; just call ops->listen. + (S_socket_accept): Remove extra checks before ops->accept call. + Avoid use of goto. + (S_socket_connect): Remove extra checks; just call ops->connect. + (S_socket_bind): Adjust for struct sock_addr changes. + (S_socket_create_address): Likewise. + (S_socket_whatis_address): Likewise. + (S_socket_connect2): Don't diddle data structures after + ops->socketpair call. + (S_socket_getopt): Use sock_getsockopt if LEVEL is SOL_SOCKET. + Accept any data size, not just sizeof (int). + (S_socket_setopt): Use sock_setsockopt if LEVEL is SOL_SOCKET. + (S_socket_send): Always use ops->sendmsg instead of ops->send or + ops->sendto, which no longer exist. If O_NONBLOCK is set, set + MSG_DONTWAIT in msg_flags. + (S_socket_recv): Always use ops->recvmsg instead of ops->recv, which + no longer exists. If O_NONBLOCK is set, set MSG_DONTWAIT in flags. + Check for error from S_socket_create_address. + + * main.c (find_device): Don't try to set ether_dev.pa_mask (it's gone). + (main): Don't call init_devices. Call ethernet_initialize. + Start net_bh_worker instead of input_work_thread. Don't call + setup_loopback_device. Instead, take global_lock, do prepare_current, + and then call sk_init, skb_init, inet_proto_init, and net_dev_init. + Keep global_lock held while calling argp_parse. + Call arrange_shutdown_notification only after all that. + Fix error call for "contacting parent" to pass ERR instead of errno. + * options.c (ADDR): #undef before defining macro. + (parse_opt): #if 0 out EDESTADDRREQ check (I don't understand it). + To apply settings, call configure_devices. + (ADD_ADDR_OPT): #if 0 --address and --netmask options. Needs fixed. + * misc.c (make_sock_user, clean_socketport, sock_alloc, sock_release): + Functions moved to socket.c. + (sock_release_peer): Function removed. + (make_sockaddr_port): Use struct sockaddr_storage to size buffer. + Fix size calculation for new struct sock_addr layout. + Initialize sa_family and sa_len of new struct sock_addr. + + Remove the old Linux (2.0.??) network stack and the glue code for it. + * linux-inet, asm, linux: Directories and all files removed. + Some of the new files in glue-include came from the old glue headers + in the asm and linux directories, but most were substantially modified. + * devices.c: File removed. The equivalent glue is now elsewhere. + 2000-01-27 Roland McGrath <roland@baalperazim.frob.com> * mapped-time.h: Include <maptime.h>. |
