2010-10-15ath9k_hw: remove enum wireless_mode and its usersFelix Fietkau
The wireless mode bitfield was only used to detect 2.4 and 5 GHz support, which can be simplified by using ATH9K_HW_CAP_* capabilities. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-15ath9k: remove sc->cur_rate_table and sc->cur_rate_modeFelix Fietkau

2010-10-15ath9k: add missing locking around ath9k_hw_proc_mib_eventFelix Fietkau
ath9k_hw_proc_mib_event updates the cycle counters, so it common->cc_lock must be acquired. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-15ath9k_hw: fix PHY counter overflow handling in ANI v1Felix Fietkau
PHY counter overflows need to be checked for the old ANI version, because of its use of interrupt based counter overflow reports when the counters exceed the configured thresholds. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-15ath9k_hw: fix division by zero in the ANI monitor codeFelix Fietkau
The commit "ath9k_hw: remove code duplication in phy error counter handling" split off some duplicate code into a separate function, but did not have a return code for aborting ANI processing based on counter values. This introduced a divide by zero issue. This patch adds the missing return code check in ath9k_hw_ani_monitor Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-15ath9k: do not track cycle counter updates in powersave modeFelix Fietkau
While the chip is in powersave mode, the cycle counter updates do not contain useful values. While the chip is in full sleep, the rx_clear signal stays high, indicating a busy medium. To ensure sane values, update cycle counters before going into powersave, and clear them right after switching back to awake. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-15ixgbe: DCB: remove DCB check configJohn Fastabend
Remove a DCB check config from DCB configuration we continue to configure DCB even if it fails so don't even bother to check. Plus user space (lldpad) checks this before programming the hw anyways. Worse case is we program some values into the hw that don't make total sense resulting in incorrect bandwidth allocation.

Add new interrupt ack functions and other hardware interface logic to support the new device. Update version to 2.2.6. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-10-14cnic: Decouple uio close from cnic shutdownMichael Chan
During cnic shutdown, the original driver code requires userspace to close the uio device within a few seconds. This doesn't always happen as the userapp may be hung or otherwise take a long time to close. The system may crash when this happens. We fix the problem by decoupling the uio structures from the cnic structures during cnic shutdown. We do not unregister the uio device until the cnic driver is unloaded. This eliminates the unreliable wait loop for uio to close. All uio structures are kept in a linked list. If the device is shutdown and later brought back up again, the uio strcture will be found in the linked list and coupled back to the cnic structures.

2010-10-14cnic: Defer iscsi connection cleanupMichael Chan
The bnx2x devices require a 2 second quiet time before sending the last RAMROD command to destroy a connection. This sleep wait adds up to a long delay when iscsid is serially destroying maultiple connections. Create a workqueue to perform the final connection cleanup in the background to speed up the process. This significantly speeds up the process as the wait time can be done in parallel for multiple connections. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2010-10-14iwlagn: check beacon frame sizeJohannes Berg

2010-10-14iwlwifi: rewrite RXON checksJohannes Berg
The RXON checking is a bit magical, and prints out too much information if something goes wrong. Make it less magical and print out only the items that were actually wrong. Also remove the comment about removing it -- the driver is constantly changing so these checks are useful. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2010-10-14iwlwifi: clean up some beacon handlingJohannes Berg
There's no need to check for NULL before calling dev_kfree_skb() since it is valid to call it on NULL -- it becomes a no-op. There's also no need to initialise the beacon_skb variable to NULL just after the memory it is in has been kzalloc'ed. Some minor whitespace cleanups, and a lock assertion in a function that needs the mutex (to access the beacon_skb var) complete the patch.

2010-10-14iwlwifi: allow probe-after-rx on 2.4 GHzJohannes Berg
There are two passive 2.4 GHz channels: 12 and 13. If you have a hidden SSID on those, you will not be able to connect to it because we don't send out probe requests there. We can allow this by using the firmware's probe-after-rx functionality on those channels as well.

The patch does following:- - Removes setsockopts for PNPIPE_CREATE and PNPIPE_DESTROY - Adds setsockopt for setting the Pipe handle value - Implements connect socket call - Updates the Pipe controller logic User-space should now follow below sequence with Pipe controller:- -socket -bind -setsockopt for PNPIPE_PIPE_HANDLE -connect -setsockopt for PNPIPE_ENCAP_IP -setsockopt for PNPIPE_ENABLE GPRS/3G data has been tested working fine with this.

2010-10-13wext: fix alignment problem in serializing 'struct iw_point'Gerrit Renker
wext: fix alignment problem in serializing 'struct iw_point' This fixes a typo in the definition of the serialized length of struct iw_point: a) wireless.h is exported to userspace, the typo causes IW_EV_POINT_PK_LEN to be 12 on 64-bit, and 8 on 32-bit systems (causing misalignment); b) in compat-64 mode iwe_stream_add_point() memcpys overlap (see below). The second case in in compat-64 mode looks like (variable names are as in include/net/iw_handler.h:iwe_stream_add_point()): point_len = IW_EV_COMPAT_POINT_LEN = 8 lcp_len = IW_EV_COMPAT_LCP_LEN = 4 2nd memcpy: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 12 - 4 = 8 IW_EV_LCP_PK_LEN <--------------> *---> 'extra' data area +-------+-------+-------+-------+---------------+------- ...-+ | len | cmd |length | flags | (empty) -> extra ... | +-------+-------+-------+-------+---------------+------- ...-+ 2 2 2 2 4 lcp_len <--------------> <-!! OVERLAP !!> <--1st memcpy--><------- 2nd memcpy -----------> <---- 3rd memcpy ------- ... > <--------- point_len ----------> This case could cause overrun whenever iw_point.length < 4. The other two cases are - * 32-bit systems: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 8 - 4 = 4, the second memcpy copies exactly the 4 required bytes; * 64-bit systems: IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN = 12 - 4 = 8, the second memcpy copies a superfluous (but non overlapping) 4 bytes. The patch changes IW_EV_POINT_PK_LEN to be 8, so that in all 3 cases always only the requested iw_point.{length,flags} (both __u16) are copied, avoiding overrrun (compat-64) and superfluous copy (64-bit). In addition, the userspace header is sanitized (in agreement with version 30 of the wireless tools). Many thanks to Johannes Berg for help and review with this patch.

We tried very hard to remove all possible dev_hold()/dev_put() pairs in network stack, using RCU conversions. There is still an unavoidable device refcount change for every dst we create/destroy, and this can slow down some workloads (routers or some app servers, mmap af_packet) We can switch to a percpu refcount implementation, now dynamic per_cpu infrastructure is mature. On a 64 cpus machine, this consumes 256 bytes per device.
