2015-08-14mac80211_hwsim: unregister genetlink family properlySu Kang Yin1-1/+3
During hwsim_init_netlink(), we should call genl_unregister_family() if failed on netlink_register_notifier() since the genetlink is already registered. Signed-off-by: Su Kang Yin <cantona@cantona.net> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg1-13/+13
As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg1-2/+0
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-04-22mac80211_hwsim: enable IEEE80211_HW_SUPPORT_FAST_XMITJohannes Berg1-1/+2
For hwsim, the duration field in frames is already not valid for the common case of HT/VHT MCSes, so there's little point in trying to keep it accurate for the legacy rates. Enable the fast-xmit code to allow testing that, although given the dependency on hardware crypto it will only be enabled in open network configurations.

2015-03-04mac80211_hwsim: fix beacon timersJohannes Berg1-9/+6
Jouni reported that certain combinations of hwsim test cases failed, and we found that beaconing was erroneously enabled too early on any channel switch, which lead to the BI of 2000 TU from the first test case to leak into the second one, which then didn't beacon properly. To fix this, set data->beacon_int to zero when all stop beaconing so that beaconing cannot be started (which was intended as 'restarted') elsewhere. Additionally, Jouni found that due to this 'restart' and the beacon interval handling station interfaces would also have a needlessly running beacon timer all the time, of course not doing anything. To also fix the latter case only use the beacon interval when it's actually needed, i.e. when beaconing gets enabled.

2015-02-24mac80211_hwsim: fix error handling in tx_frame_nlBob Copeland1-1/+4
Correct two problems with the error handling when using the netlink forwarding API: first, the netlink skb is never freed if nla_put() fails; and second, genlmsg_unicast() can fail if the netlink socket is full. In the latter case, the corresponding data skb is not counted as a drop and userspace programs like wmediumd will see TCP stalls due to lost packets.

2015-01-18netlink: make nlmsg_end() and genlmsg_end() voidJohannes Berg1-1/+2
Contrary to common expectations for an "int" return, these functions return only a positive value -- if used correctly they cannot even return 0 because the message header will necessarily be in the skb. This makes the very common pattern of if (genlmsg_end(...) < 0) { ... } be a whole bunch of dead code. Many places also simply do return nlmsg_end(...); and the caller is expected to deal with it. This also commonly (at least for me) causes errors, because it is very common to write if (my_function(...)) /* error condition */ and if my_function() does "return nlmsg_end()" this is of course wrong. Additionally, there's not a single place in the kernel that actually needs the message length returned, and if anyone needs it later then it'll be very easy to just use skb->len there. Remove this, and make the functions void. This removes a bunch of dead code as described above. The patch adds lines because I did - return nlmsg_end(...); + nlmsg_end(...); + return 0; I could have preserved all the function's return values by returning skb->len, but instead I've audited all the places calling the affected functions and found that none cared. A few places actually compared the return value with <= 0 in dump functionality, but that could just be changed to < 0 with no change in behaviour, so I opted for the more efficient version. One instance of the error I've made numerous times now is also present in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't check for <0 or <=0 and thus broke out of the loop every single time. I've preserved this since it will (I think) have caused the messages to userspace to be formatted differently with just a single message for every SKB returned to userspace. It's possible that this isn't needed for the tools that actually use this, but I don't even know what they are so couldn't test that changing this behaviour would be acceptable.

2014-10-09mac80211-hwsim: Add support for HWSIM_ATTR_DESTROY_RADIO_ON_CLOSEJukka Rissanen1-3/+37
Add support for new attribute HWSIM_ATTR_DESTROY_RADIO_ON_CLOSE which can be set by the user space component. The attribute will cause the kernel to destroy all those radios that were created by a process if that process dies. The old behaviour i.e., radios are persistent is still the default.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-07-25 Please pull this batch of updates intended for the 3.17 stream! For the mac80211 bits, Johannes says: "We have a lot of TDLS patches, among them a fix that should make hwsim tests happy again. The rest, this time, is mostly small fixes." For the Bluetooth bits, Gustavo says: "Some more patches for 3.17. The most important change here is the move of the 6lowpan code to net/6lowpan. It has been agreed with Davem that this change will go through the bluetooth tree. The rest are mostly clean up and fixes." and, "Here follows some more patches for 3.17. These are mostly fixes to what we've sent to you before for next merge window." For the iwlwifi bits, Emmanuel says: "I have the usual amount of BT Coex stuff. Arik continues to work on TDLS and Ariej contributes a few things for HS2.0. I added a few more things to the firmware debugging infrastructure. Eran fixes a small bug - pretty normal content." And for the Atheros bits, Kalle says: "For ath6kl me and Jessica added support for ar6004 hw3.0, our latest version of ar6004. For ath10k Janusz added a printout so that it's easier to check what ath10k kconfig options are enabled. He also added a debugfs file to configure maximum amsdu and ampdu values. Also we had few fixes as usual." On top of that is the usual large batch of various driver updates -- brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action. Rafał has also been very busy with b43 and related updates. Also, I pulled the wireless tree into this in order to resolve a merge conflict... P.S. The change to fs/compat_ioctl.c reflects a name change in a Bluetooth header file... ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-23mac80211_hwsim: fix compiler warning on MIPSAndrew Bresticker1-3/+8
The dividend in do_div() is expected to be an unsigned 64-bit integer, which leads to the following warning when building for 32-bit MIPS: drivers/net/wireless/mac80211_hwsim.c: In function 'mac80211_hwsim_set_tsf': drivers/net/wireless/mac80211_hwsim.c:664:98: warning: comparison of distinct pointer types lacks a cast [enabled by default] data->bcn_delta = do_div(delta, bcn_int); Since we care about the signedness of delta when adjusting tsf_offset and bcm_delta, use the absolute value for the division and compare the two timestamps to determine the sign.
