2015-10-28airo: fix scan after SIOCSIWAP (airo_set_wap)Ondrej Zary1-3/+17
SIOCSIWAP (airo_set_wap) affects scan: only the AP specified by SIOCSIWAP is present in scan results. This makes NetworkManager work for the first time but then unable to find any other APs. Clear APList before starting scan and set it back after scan completes to work-around the problem. To avoid losing packets during scan, modify disable_MAC() to omit netif_carrier_off() call when lock == 2.

2015-10-28airo: Track APList_rid in struct airo_infoOndrej Zary1-38/+19
Instead of dynamically allocating APList, make it a member of struct airo_info to always track state of APList_rid. This simplifies suspend/resume and allows removal of readAPListRid. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2015-09-29airo: fix IW_AUTH_ALG_OPEN_SYSTEMOndrej Zary1-24/+35
IW_AUTH_ALG_OPEN_SYSTEM is ambiguous in set_auth for WEP as wpa_supplicant uses it for both no encryption and WEP open system. Cache the last mode set (only of these two) and use it here. This allows wpa_supplicant to work with unencrypted APs. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-04-15Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-nextLinus Torvalds1-2/+2
Pull networking updates from David Miller: 1) Add BQL support to via-rhine, from Tino Reichardt. 2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers can support hw switch offloading. From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...

2012-10-18wireless: drivers: make use of WLAN_EID_VENDOR_SPECIFICArend van Spriel1-1/+1
The include file linux/ieee80211.h contains three definitions for the same thing in enum ieee80211_eid due to historic changes: /* Information Element IDs */ enum ieee80211_eid { : WLAN_EID_WPA = 221, WLAN_EID_GENERIC = 221, WLAN_EID_VENDOR_SPECIFIC = 221, : }; The standard refers to this as "vendor specific" element so the other two definitions are better not used. This patch changes the wireless drivers to use one definition, ie. WLAN_EID_VENDOR_SPECIFIC.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann1-8/+16
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-09-24airo: remove "basic_rate" module optionDan Carpenter1-11/+0
The "basic_rate" module option is not implemented correctly. If the rate was set to zero it was supposed to set it to "basic_rate | 0x80". Unfortunately the check to see if what zero was wrong and it checked "!ai->config.rates" (which is always false) instead of "!ai->config.rates[i]". This option was just used for development and it wasn't documented anywhere. Instead of fixing it, we can just remove it.

2010-08-17drivers/net: Convert unbounded kzalloc calls to kcallocJoe Perches1-3/+2
These changes may be slightly safer in some instances. There are other kzalloc calls with a multiply, but those calls are typically "small fixed #" * sizeof(some pointer)" and those are not converted.
