Metricom radios are small, battery - powered, 100kbit/sec packet radio transceivers, about the size and - weight of a cellular telephone. (You may also have heard them called - "Metricom modems" but we avoid the term "modem" because it misleads - many people into thinking that you can plug a Metricom modem into a - phone line and use it as a modem.) - - You can use STRIP on any Linux machine with a serial port, although - it is obviously most useful for people with laptop computers. If you - think you might get a Metricom radio in the future, there is no harm - in saying Y to STRIP now, except that it makes the kernel a bit - bigger. - - To compile this as a module, choose M here: the module will be - called strip. - config ARLAN tristate "Aironet Arlan 655 & IC2200 DS support" depends on ISA && !64BIT && WLAN_PRE80211 diff --git a/drivers/net/wireless/Makefile b/drivers/net/wireless/Makefile index 54a4f6f1db6..2668934abbf 100644 --- a/drivers/net/wireless/Makefile +++ b/drivers/net/wireless/Makefile @@ -6,7 +6,6 @@ obj-$(CONFIG_IPW2100) += ipw2100.o obj-$(CONFIG_IPW2200) += ipw2200.o -obj-$(CONFIG_STRIP) += strip.o obj-$(CONFIG_ARLAN) += arlan.o arlan-objs := arlan-main.o arlan-proc.o diff --git a/drivers/net/wireless/adm8211.c b/drivers/net/wireless/adm8211.c index 0ba55ba9395..3333d4596b8 100644 --- a/drivers/net/wireless/adm8211.c +++ b/drivers/net/wireless/adm8211.c @@ -1685,7 +1685,6 @@ static void adm8211_tx_raw(struct ieee80211_hw *dev, struct sk_buff *skb, static int adm8211_tx(struct ieee80211_hw *dev, struct sk_buff *skb) { struct adm8211_tx_hdr *txhdr; - u16 fc; size_t payload_len, hdrlen; int plcp, dur, len, plcp_signal, short_preamble; struct ieee80211_hdr *hdr; @@ -1696,8 +1695,7 @@ static int adm8211_tx(struct ieee80211_hw *dev, struct sk_buff *skb) plcp_signal = txrate->bitrate; hdr = (struct ieee80211_hdr *)skb->data; - fc = le16_to_cpu(hdr->frame_control) & ~IEEE80211_FCTL_PROTECTED; - hdrlen = ieee80211_get_hdrlen(fc); + hdrlen = ieee80211_hdrlen(hdr->frame_control); memcpy(skb->cb, skb->data, hdrlen); hdr = (struct ieee80211_hdr *)skb->cb; skb_pull(skb, hdrlen); @@ -1711,8 +1709,6 @@ static int adm8211_tx(struct ieee80211_hw *dev, struct sk_buff *skb) txhdr->frame_control = hdr->frame_control; len = hdrlen + payload_len + FCS_LEN; - if (fc & IEEE80211_FCTL_PROTECTED) - len += 8; txhdr->frag = cpu_to_le16(0x0FFF); adm8211_calc_durations(&dur, &plcp, payload_len, @@ -1730,9 +1726,6 @@ static int adm8211_tx(struct ieee80211_hw *dev, struct sk_buff *skb) if (info->flags & IEEE80211_TX_CTL_USE_RTS_CTS) txhdr->header_control |= cpu_to_le16(ADM8211_TXHDRCTL_ENABLE_RTS); - if (fc & IEEE80211_FCTL_PROTECTED) - txhdr->header_control |= cpu_to_le16(ADM8211_TXHDRCTL_ENABLE_WEP_ENGINE); - txhdr->retry_limit = info->control.retry_limit; adm8211_tx_raw(dev, skb, plcp_signal, hdrlen); diff --git a/drivers/net/wireless/airo.c b/drivers/net/wireless/airo.c index e30f8b79ea8..b5cd850a4a5 100644 --- a/drivers/net/wireless/airo.c +++ b/drivers/net/wireless/airo.c @@ -85,10 +85,10 @@ static struct pci_driver airo_driver = { /* Include Wireless Extension definition and check version - Jean II */ #include <linux/wireless.h> -#define WIRELESS_SPY // enable iwspy support -#include <net/iw_handler.h> // New driver API +#define WIRELESS_SPY /* enable iwspy support */ +#include <net/iw_handler.h> /* New driver API */ -#define CISCO_EXT // enable Cisco extensions +#define CISCO_EXT /* enable Cisco extensions */ #ifdef CISCO_EXT #include <linux/delay.h> #endif @@ -281,7 +281,7 @@ MODULE_PARM_DESC(proc_perm, "The permission bits of the files in /proc"); /* This is a kind of sloppy hack to get this information to OUT4500 and IN4500.

However, if the user *does* manually set the hardware - * source address of a STRIP interface, then the kernel will believe it, - * and use it in certain places. For example, the hardware address listed - * by ifconfig will be the manual address, not the true one. - * (Both addresses are listed in /proc/net/strip.) - * Also, ARP packets will be sent out giving the user-specified address as - * the source address, not the real address. This is dangerous, because - * it means you won't receive any replies -- the ARP replies will go to - * the specified address, which will be some other radio. The case where - * this is useful is when that other radio is also connected to the same - * machine. This allows you to connect a pair of radios to one machine, - * and to use one exclusively for inbound traffic, and the other - * exclusively for outbound traffic. Pretty neat, huh? - * - * Here's the full procedure to set this up: - * - * 1. "slattach" two interfaces, e.g. st0 for outgoing packets, - * and st1 for incoming packets - * - * 2. "ifconfig" st0 (outbound radio) to have the hardware address - * which is the real hardware address of st1 (inbound radio). - * Now when it sends out packets, it will masquerade as st1, and - * replies will be sent to that radio, which is exactly what we want. - * - * 3. Set the route table entry ("route add default ..." or - * "route add -net ...", as appropriate) to send packets via the st0 - * interface (outbound radio). Do not add any route which sends packets - * out via the st1 interface -- that radio is for inbound traffic only. - * - * 4. "ifconfig" st1 (inbound radio) to have hardware address zero. - * This tells the STRIP driver to "shut down" that interface and not - * send any packets through it. In particular, it stops sending the - * periodic gratuitous ARP packets that a STRIP interface normally sends. - * Also, when packets arrive on that interface, it will search the - * interface list to see if there is another interface who's manual - * hardware address matches its own real address (i.e. st0 in this - * example) and if so it will transfer ownership of the skbuff to - * that interface, so that it looks to the kernel as if the packet - * arrived on that interface. This is necessary because when the - * kernel sends an ARP packet on st0, it expects to get a reply on - * st0, and if it sees the reply come from st1 then it will ignore - * it (to be accurate, it puts the entry in the ARP table, but - * labelled in such a way that st0 can't use it). - * - * Thanks to Petros Maniatis for coming up with the idea of splitting - * inbound and outbound traffic between two interfaces, which turned - * out to be really easy to implement, even if it is a bit of a hack. - * - * Having set a manual address on an interface, you can restore it - * to automatic operation (where the address is automatically kept - * consistent with the real address of the radio) by setting a manual - * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF" - * This 'turns off' manual override mode for the device address. - * - * Note: The IEEE 802 headers reported in tcpdump will show the *real* - * radio addresses the packets were sent and received from, so that you - * can see what is really going on with packets, and which interfaces - * they are really going through. - */ - - -/************************************************************************/ -/* Constants */ - -/* - * CommandString1 works on all radios - * Other CommandStrings are only used with firmware that provides structured responses. - * - * ats319=1 Enables Info message for node additions and deletions - * ats319=2 Enables Info message for a new best node - * ats319=4 Enables checksums - * ats319=8 Enables ACK messages - */ - -static const int MaxCommandStringLength = 32; -static const int CompatibilityCommand = 1; - -static const char CommandString0[] = "*&COMMAND*ATS319=7"; /* Turn on checksums & info messages */ -static const char CommandString1[] = "*&COMMAND*ATS305?"; /* Query radio name */ -static const char CommandString2[] = "*&COMMAND*ATS325?"; /* Query battery voltage */ -static const char CommandString3[] = "*&COMMAND*ATS300?"; /* Query version information */ -static const char CommandString4[] = "*&COMMAND*ATS311?"; /* Query poletop list */ -static const char CommandString5[] = "*&COMMAND*AT~LA"; /* Query portables list */ -typedef struct { - const char *string; - long length; -} StringDescriptor; - -static const StringDescriptor CommandString[] = { - {CommandString0, sizeof(CommandString0) - 1}, - {CommandString1, sizeof(CommandString1) - 1}, - {CommandString2, sizeof(CommandString2) - 1}, - {CommandString3, sizeof(CommandString3) - 1}, - {CommandString4, sizeof(CommandString4) - 1}, - {CommandString5, sizeof(CommandString5) - 1} -}; - -#define GOT_ALL_RADIO_INFO(S) \ - ((S)->firmware_version.c[0] && \ - (S)->battery_voltage.c[0] && \ - memcmp(&(S)->true_dev_addr, zero_address.c, sizeof(zero_address))) - -static const char hextable[16] = "0123456789ABCDEF"; - -static const MetricomAddress zero_address; -static const MetricomAddress broadcast_address = - { {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF} }; - -static const MetricomKey SIP0Key = { "SIP0" }; -static const MetricomKey ARP0Key = { "ARP0" }; -static const MetricomKey ATR_Key = { "ATR " }; -static const MetricomKey ACK_Key = { "ACK_" }; -static const MetricomKey INF_Key = { "INF_" }; -static const MetricomKey ERR_Key = { "ERR_" }; - -static const long MaxARPInterval = 60 * HZ; /* One minute */ - -/* - * Maximum Starmode packet length is 1183 bytes.
