The memory layout for scan requests was rather wrong, we put the scan SSIDs before the channels which could lead to the channel pointers being unaligned in memory. It turns out that using a pointer to the channel array isn't necessary anyway since we can embed a zero-length array into the struct. Signed-off-by:

If we have a lot of frames to transmit at once, for instance with fragmentation, it can be an optimisation to only tell the DMA engine about them on the last fragment/frame to avoid banging the IO too much. This patch allows implementation such an optimisation by telling the driver when more frames can be expected. Currently, this is used by mac80211 only on fragmented frames, but could also be used in the future on other frames when the queue was full and there are multiple frames pending. Note that drivers need to be careful when using this flag, they need to kick their DMA engines not just when this flag is clear, but also when the queue gets full so that progress can be made.

In order for userspace to be able to figure out whether it obtained a consistent snapshot of data or not when using netlink dumps, we need to have a generation number in each dump message that indicates whether the list has changed or not -- its value is arbitrary. This patch adds such a number to all dumps, this needs some mac80211 involvement to keep track of a generation number to start with when adding/removing mesh paths or stations. The wiphy and netdev lists can be fully handled within cfg80211, of course, but generation numbers need to be stored there as well. Signed-off-by:

With the move of everything related to the SME from mac80211 to cfg80211, we lost the ability to send reassociation frames. This adds them back, but only for wireless extensions. With the userspace SME, it shall control assoc vs. reassoc (it already can do so with the nl80211 interface). I haven't touched the connect() implementation, so it is not possible to reassociate with the nl80211 connect primitive. I think that should be done with the NL80211_CMD_ROAM command, but we'll have to see how that can be handled in the future, especially with fullmac chips. This patch addresses only the immediate regression we had in mac80211, which previously sent reassoc. Signed-off-by:

Currently, there's a problem that affects regulatory enforcement and connection stability, in that it is possible to switch the channel while connected to a network or joined to an IBSS. The problem comes from the fact that we only validate the channel against the current interface's type, not against any other interface. Thus, you have any type of interface up, additionally bring up a monitor mode interface and switch the channel on the monitor. This will obviously also switch the channel on the other interface. The problem now is that if you do that while sending beacons for IBSS mode, you can switch to a disabled channel or a channel that doesn't allow beaconing. Combined with a managed mode interface connected to an AP instead of an IBSS interface, you can easily break the connection that way. To fix this, this patch validates any channel change with all available interfaces, and disallows such changes on secondary interfaces if another interface is connected to an AP or joined to an IBSS.

Commit 9cef8737 "mac80211: fix managed mode BSSID handling" broke association in wl1251, most probably because the driver configured the bssid filter incorrectly. Workaround this by disabling filter altogether. This needs to be fixed properly soon. Signed-off-by:

There is a bug in wl1251_op_config(). It was calling join with previous channel. Fix it by setting assigning wl->channel before calling join command. Signed-off-by:

Better to use wl1251_cmd_join() only for sending the command and move the logic to wl1251_join(). Signed-off-by:

Because join channel tunes to a channel, better to make it more obvious by adding a parameter for it. Signed-off-by:

In SDIO, the host driver requests the IRQ and invokes a callback to the card driver. This differs from SPI, so the relevant code needs to be interface-specific. This patch pushes the irq code down into _spi.c and _sdio.c, and adds enable/disable callbacks. This fixes the following warning: [ 566.343887] ------------[ cut here ]------------ [ 566.349105] WARNING: at kernel/irq/manage.c:222 __enable_irq+0x3c/0x6c() [ 566.356735] Unbalanced enable for IRQ 0 [ 566.361099] Modules linked in: msm_wifi wl12xx_sdio wl12xx mac80211 cfg80211 rfkill_backport lib80211_crypt_ccmp lib80211_crypt_wep lib80211_crypt_tkip lib80211 [ 566.381240] [<c025acec>] (dump_stack+0x0/0x14) from [<c004b610>] (warn_slowpath+0x70/0x8c) [ 566.391860] [<c004b5a0>] (warn_slowpath+0x0/0x8c) from [<c0077c10>] (__enable_irq+0x3c/0x6c) [ 566.402572] r3:00000000 r2:c02cad13 [ 566.407516] r7:00001002 r6:00000000 r5:c0310be4 r4:c0310be4 [ 566.415786] [<c0077bd4>] (__enable_irq+0x0/0x6c) from [<c0077fd0>] (enable_irq+0x38/0x64) [ 566.425826] r5:c0310be4 r4:a0000013 [ 566.430709] [<c0077f98>] (enable_irq+0x0/0x64) from [<bf0dfa78>] (wl12xx_boot_run_firmware+0xfc/0x170 [wl12xx]) [ 566.442947] r7:00001002 r6:c440a9fc r5:00000072 r4:c440a9e0 [ 566.450851] [<bf0df97c>] (wl12xx_boot_run_firmware+0x0/0x170 [wl12xx]) from [<bf0e05f0>] (wl1251_boot+0xd4/0x108 [wl12xx]) [ 566.464492] r5:00000000 r4:c440a9e0 [ 566.469466] [<bf0e051c>] (wl1251_boot+0x0/0x108 [wl12xx]) from [<bf0dd27c>] (wl12xx_op_start+0x54/0xb8 [wl12xx]) [ 566.482162] r5:00000000 r4:c440a9e0 [ 566.487472] [<bf0dd228>] (wl12xx_op_start+0x0/0xb8 [wl12xx]) from [<bf0b96dc>] (ieee80211_open+0x2dc/0x720 [mac80211]) [ 566.500594] r7:00001002 r6:c4950800 r5:c440a220 r4:00000000 [ 566.508865] [<bf0b9400>] (ieee80211_open+0x0/0x720 [mac80211]) from [<c01f1edc>] (dev_open+0x9c/0xfc) [ 566.520705] [<c01f1e40>] (dev_open+0x0/0xfc) from [<c01f17dc>] (dev_change_flags+0x98/0x170) [ 566.531417] r5:00000041 r4:c4950800 [ 566.536330] [<c01f1744>] (dev_change_flags+0x0/0x170) from [<c023041c>] (devinet_ioctl+0x3a8/0x784) [ 566.547683] r7:c128e380 r6:00000001 r5:00008914 r4:00000000 [ 566.555587] [<c0230074>] (devinet_ioctl+0x0/0x784) from [<c02318cc>] (inet_ioctl+0xdc/0x114) [ 566.566299] [<c02317f0>] (inet_ioctl+0x0/0x114) from [<c01e1a60>] (sock_ioctl+0x1f0/0x248) [ 566.576827] r5:00008914 r4:c572c1a0 [ 566.581771] [<c01e1870>] (sock_ioctl+0x0/0x248) from [<c00b23a0>] (vfs_ioctl+0x34/0x94) [ 566.592086] r7:c572c1a0 r6:bee497e8 r5:00008914 r4:c572c1a0 [ 566.599990] [<c00b236c>] (vfs_ioctl+0x0/0x94) from [<c00b2a28>] (do_vfs_ioctl+0x52c/0x584) [ 566.610549] r7:c572c1a0 r6:00008914 r5:c572c1a0 r4:c3201228 [ 566.618453] [<c00b24fc>] (do_vfs_ioctl+0x0/0x584) from [<c00b2ac0>] (sys_ioctl+0x40/0x64) [ 566.628890] [<c00b2a80>] (sys_ioctl+0x0/0x64) from [<c0021da0>] (ret_fast_syscall+0x0/0x2c) [ 566.639541] r7:00000036 r6:00000000 r5:00000004 r4:001a11f3 [ 566.647445] ---[ end trace 15c26ef7dd5e7b03 ]--- Signed-off-by:

This change moves all of the spi specific code from main.c into spi.c. The module initialization code also moves, but common code for initializing mac80211 etc. stays in main.c, as this will eventually form a common library module also used by wl1251_sdio. Signed-off-by:

The same partition setting code can be used for both SPI and SDIO modes, if we remove the spi-specific commands and use the more generic buffer write routines. Do that and move it to io.c since it deals with register/memory address offsets. Signed-off-by:

In order to eventually support wl1251 spi and sdio interfaces, move the register and memory transfer functions to a common file. Also rename wl1251_spi_mem_{read,write} to indicate its common usage. We still use spi_read internally until SDIO interface is introduced so nothing functional should change here. Signed-off-by: -
