This fixes a long list of undefined references when compiling with -O0
by using static instead of extern in header files.

* 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'.
|

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.

* pfinet/linux-src/net/ipv4/af_inet.c (inet_getname): Clear `sin_zero'
part of `sin'.

Make empty bodies of control flow statements more explicit. Doing so
will allow us to use stricter compiler settings. This would have
cought 4ece292c.

Some files were not normalized. In console/motd.UTF8 the additional
newline is intentional. Empty files were excluded as well.

kfree_s expects a pointer and a size argument. Currently the
sizeof(cache) is used as size argument, this is certainly not what was
intented.
For reference, this code was present in Linux up to version 2.3.14 and
was replaced in 2.3.15.
Found using coccinelle and
https://raw.github.com/coccinelle/coccinellery/master/sz/sz.cocci.
* pfinet/linux-src/net/ipv4/ipmr.c (ipmr_cache_delete): Fix kfree_s call.

Complete overhaul of pfinet based on the IPv4 networking code from the
Linux 2.2.12 kernel sources. 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_.

refcnt and identity; elide members fasync_list, file.

and SIOCSIFNETMASK code from devinet_ioctl.

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.

(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.

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.

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.
