There is a bug in do_tcp_setsockopt(net/ipv4/tcp.c), TCP_COOKIE_TRANSACTIONS case. In some cases (when tp->cookie_values == NULL) new tcp_cookie_values structure can be allocated (at cvp), but not bound to tp->cookie_values. So a memory leak occurs.

2010-07-29mac80211: allow drivers to request DTIM periodJohannes Berg4-3/+77

2010-07-28mac80211: inform drivers about the off-channel status on channel changesFelix Fietkau1-0/+3
For some drivers it can be useful to know whether the channel they're supposed to switch to is going to be used for short off-channel work or scanning, or whether the hardware is expected to stay on it for a while longer. This is important for various kinds of calibration work, which takes longer to complete and should keep some persistent state, even if the channel temporarily changes.

2010-07-28Revert "mac80211: fix sw scan bracketing"Luis R. Rodriguez1-2/+2
This reverts this commit. While in theory the change is correct the patch does not address current assumptions made by some drivers, one which is definitley affected is ath9k. Prior to this change the scan complete callback would be called after we returned to the home channel and configured the hardware RX filters. After this change we call the scan complete callback prior to both the hw config and the config filter. At least for ath9k this breaks quite a few assumptions on the callback, leading to disconnects to the AP after every scan making the driver pretty useless on STA mode. The goal behind this commit was to address the now understood spurious warnings from ath9k and mac80211_hwsim on scanning on two wiphys at the same time but we have now supressed these and will address this issue in the next kernel release. When fixing this for good next we must first review the other driver's dependence on this logic and perhaps consider removal of the scan complete callback all together.

2010-07-27mac80211: Fix key freeing to handle unlinked keysJouni Malinen4-12/+12
Key locking simplification removed key->sdata != NULL verification from ieee80211_key_free(). While that is fine for most use cases, there is one path where this function can be called with an unlinked key (i.e., key->sdata == NULL && key->local == NULL). This results in a NULL pointer dereference with the current implementation. This is known to happen at least with FT protocol when wpa_supplicant tries to configure the key before association. Avoid the issue by passing in the local pointer to ieee80211_key_free(). In addition, do not clear the key from hw_accel or debugfs if it has not yet been added. At least the hw_accel one could trigger another NULL pointer dereference. Signed-off-by: Jouni Malinen <[email protected]> Reviewed-by: Johannes Berg <[email protected]> Signed-off-by: John W.

2010-07-24sysfs: add attribute to indicate hw address assignment typeStefan Assmann1-0/+2
Add addr_assign_type to struct net_device and expose it via sysfs. This new attribute has the purpose of giving user-space the ability to distinguish between different assignment types of MAC addresses. For example user-space can treat NICs with randomly generated MAC addresses differently than NICs that have permanent (locally assigned) MAC addresses. For the former udev could write a persistent net rule by matching the device path instead of the MAC address. There's also the case of devices that 'steal' MAC addresses from slave devices. In which it is also be beneficial for user-space to be aware of the fact. This patch also introduces a helper function to assist adoption of drivers that generate MAC addresses randomly.
