First, change cfg80211 to use debugfs_remove_recursive() so that drivers do not need to clean up any files they added to the per-wiphy debugfs (if and only if they are ok to be accessed until after wiphy_unregister!). Then also make mac80211 use debugfs_remove_recursive() where necessary -- it need not remove per-wiphy files as cfg80211 now removes those, but netdev etc. files still need to be handled but can now be removed without needing struct dentry pointers to all of them.

Vice versa, if the hardware is operating on 5 GHz the 2.4 GHz probe requests will not include CCK rates even though they should. Fix this by splitting up cfg80211 scan requests by band -- recalculating the IEs every time -- and requesting only per-band scans from the driver.

Also, drivers would have to copy the code to generate the radiotap bits that now mac80211 generates. If some driver in the future needs to add some driver-specific information I'd expect that to be in a radiotap vendor namespace and we can add a different way of passing such data up and having mac80211 include it. Additionally, rename IEEE80211_CONF_RADIOTAP to IEEE80211_CONF_MONITOR since it's still used by b43(legacy) to obtain per-frame timestamps. The purpose of this patch is to simplify the RX code in mac80211 to make it easier to add paged skb support. Signed-off-by: Johannes Berg Signed-off-by: John W.

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.

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.

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.

This is another pre-802.11 driver that has seen virtually no non-API-fixup activity in years, and for which no active hardware is likely to still exist. This driver represents unnecessary ongoing maintenance for no clear benefit. This patch brought to you by the "hacking" session at the 2009 Kernel Summit in Tokyo, Japan...

Linville" Date: Wed, 28 Oct 2009 16:06:56 -0400 Subject: wavelan: move driver to staging Move the wavelan driver to drivers/staging. This is another pre-802.11 driver that has seen virtually no non-API-fixup activity in years, and for which no active hardware is likely to still exist. This driver represents unnecessary ongoing maintenance for no clear benefit. This patch brought to you by the "hacking" session at the 2009 Kernel Summit in Tokyo, Japan...

As - * the gain would be mostly for SMP systems, it can wait... - * - * Debugging and options - * --------------------- - * You will find below a set of '#define" allowing a very fine control - * on the driver behaviour and the debug messages printed. - * The main options are : - * o SET_PSA_CRC, to have your card correctly recognised by - * an access point and the Point-to-Point diagnostic tool. - * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom) - * (otherwise we always start afresh with some defaults) - * - * wavelan.o is too darned big - * --------------------------- - * That's true!

Comment out the following line: - * #include - * Other compile options can also reduce the size of it... - * - * MAC address and hardware detection: - * ----------------------------------- - * The detection code for the WaveLAN checks that the first three - * octets of the MAC address fit the company code. This type of - * detection works well for AT&T cards (because the AT&T code is - * hardcoded in wavelan.h), but of course will fail for other - * manufacturers. - * - * If you are sure that your card is derived from the WaveLAN, - * here is the way to configure it: - * 1) Get your MAC address - * a) With your card utilities (wfreqsel, instconf, etc.) - * b) With the driver: - * o compile the kernel with DEBUG_CONFIG_INFO enabled - * o Boot and look the card messages - * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h) - * 3) Compile and verify - * 4) Send me the MAC code.

As + * the gain would be mostly for SMP systems, it can wait... + * + * Debugging and options + * --------------------- + * You will find below a set of '#define" allowing a very fine control + * on the driver behaviour and the debug messages printed. + * The main options are : + * o SET_PSA_CRC, to have your card correctly recognised by + * an access point and the Point-to-Point diagnostic tool. + * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom) + * (otherwise we always start afresh with some defaults) + * + * wavelan.o is too darned big + * --------------------------- + * That's true! There is a very simple way to reduce the driver + * object by 33%! Comment out the following line: + * #include + * Other compile options can also reduce the size of it... + * + * MAC address and hardware detection: + * ----------------------------------- + * The detection code for the WaveLAN checks that the first three + * octets of the MAC address fit the company code. This type of + * detection works well for AT&T cards (because the AT&T code is + * hardcoded in wavelan.h), but of course will fail for other + * manufacturers. + * + * If you are sure that your card is derived from the WaveLAN, + * here is the way to configure it: + * 1) Get your MAC address + * a) With your card utilities (wfreqsel, instconf, etc.) + * b) With the driver: + * o compile the kernel with DEBUG_CONFIG_INFO enabled + * o Boot and look the card messages + * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h) + * 3) Compile and verify + * 4) Send me the MAC code. I will include it in the next version. + * + */ + +/* --------------------- WIRELESS EXTENSIONS --------------------- */ +/* + * This driver is the first to support "wireless extensions". + * This set of extensions provides a standard way to control the wireless + * characteristics of the hardware.

Joseph started to modify Bruce's driver + * (with help of the BSDI PCMCIA driver) for PCMCIA. + * Yunzhou Li finished this work. + * Joe Finney patched the driver to start + * 2.00 cards correctly (2.4 GHz with frequency selection). + * David Hinds integrated the whole in his + * PCMCIA package (and bug corrections). + * + * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some + * patches to the PCMCIA driver. Later, I added code in the ISA driver + * for Wireless Extensions and full support of frequency selection + * cards. Then, I did the same to the PCMCIA driver, and did some + * reorganisation.

Linville" Date: Wed, 28 Oct 2009 16:16:38 -0400 Subject: netwave: move driver to staging Move the netwave driver to drivers/staging. This is another pre-802.11 driver that has seen virtually no non-API-fixup activity in years, and for which no active hardware is likely to still exist. This driver represents unnecessary ongoing maintenance for no clear benefit. This patch brought to you by the "hacking" session at the 2009 Kernel Summit in Tokyo, Japan...

The changes account for: * Supporting ar9271 1.0 and ar9271 1.1 together, the difference is bb_spectral_scan_ena, for 1.0 we'll set this to 0x1. * Ensuring we get the correct noise floor values -115 ~ -118 when we enable bb_enable_ant_div_lnadiv=0 and mc_tx_def_ant_sel=1. Previous to this we would get noise floor values in the range -50 ~ -80. To fix settings for the registers: - bb_ch1_xatten1_db - bb_ch1_xatten2_db - bb_ch1_xatten1_margin - bb_ch1_xatten2_margin - bb_ch1_gain_force - bb_ch1_xatten2_hyst_margin - bb_ch1_xatten1_hyst_margin - bb_ch1_max_oc_gain * 0x8120[2] mc_mic_new_location_enable is changed to 0x1. The MAC team suggest to set this value. * 0x9910[0] bb_spectral_scan_ena is changed to 0x0. For ar9271 1.1 we don't need to enable this bit. Cc: Stephen Chen Signed-off-by: Luis R.

What should be clearer now is the what we do for old pre AR5416 and AR5418 MAC based devices in comparison to the modern sigle-chip 802.11n solutions. All devices after AR9280 are single chip and require less programming -- the RF registers no longer need to be initialized as they all have the RF analog front end embedded together with the MAC/BB; this includes the AR9271. Older devices such as the ones with the AR5416 MACs (PCI) or AR5418 MACs (PCI-E) have an external 2.4 GHz AR2133 radio or a dual band 2.4 GHz / 5 GHz AR5133 radio. These external radios require additional programming of the RF registers. Clarify which parts are for what devices and which code is shared. This patch has no functional changes.

This was only partially implemented with the ath9k_hw_decrease_chain_power() but first -- this was being called for all chipsets which is not correct and second -- it was missing the actual orientation code. We now ensure to only enable force bias only for AR5416 and BUG_ON() on other chipsets. Although ath9k_hw_decrease_chain_power() was enabled for newer chipsets I suspect that it never ran unless the EEPROM had ATH9K_ANT_FIXED_A or ATH9K_ANT_FIXED_B for antenna diversity.

Since it is unused anyway, this patch deprecates it in the hope that drivers will remove their sometimes quite expensive calculations of the value. I'm open to actual uses of the value, but the best way of using it seems to be what the Intel drivers do which should probably be generalised if we have noise values from the hardware.

This cleanup reduces the GSPI driver's memory footprint and should improve performance by removing the need to copy to these internal buffers. This also simplifies the bottom half of the interrupt handler. This is an incremental cleanup: after removing the redundant buffers, we can further improve the driver to use a threaded IRQ handler instead of maintaining its own thread. However I would like a few folks to test the buffer removal first and make sure that I'm not introducing regressions. Tested on Blackfin BF527 with DMA disabled due to an issue with the SPI host controller driver in the current bleeding-edge Blackfin kernel. I would appreciate it if someone with working DMA could test this patch and provide feedback. Signed-off-by: Andrey Yurovsky Tested-by: George Shore Acked-by: Dan Williams Signed-off-by: John W.

Normally, this is the case unless the station goes to sleep and wakes up very quickly again. But in that case, frames for it may be pending on the hardware queues, and thus races could happen in the case of multiple hardware queues used for QoS/WMM. Normally this isn't a problem, but with the iwlwifi mechanism we need to make sure the race doesn't happen. This makes mac80211 able to cope with the race with driver help by a new WLAN_STA_PS_DRIVER per-station flag that can be controlled by the driver and tells mac80211 whether it can transmit frames or not. This flag must be set according to very specific rules outlined in the documentation for the function that controls it. When we buffer new frames for the station, we normally set the TIM bit right away, but while the driver has blocked transmission to that sta we need to avoid that as well since we cannot respond to the station if it wakes up due to the TIM bit. Once the driver unblocks, we can set the TIM bit. Similarly, when the station just wakes up, we need to wait until all other frames are flushed before we can transmit frames to that station, so the same applies here, we need to wait for the driver to give the OK.
