* phy: power management supportGiuseppe Cavallaro2008-11-28
| | | | | | | | | | | | | | | | | | | | | | This patch adds the power management support into the physical abstraction layer. Suspend and resume functions respectively turns on/off the bit 11 into the PHY Basic mode control register. Generic PHY device starts supporting PM. In order to support the wake-on LAN and avoid to put in power down the PHY device, the MDIO is aware of what the Ethernet device wants to do. Voluntary, no CONFIG_PM defines were added into the sources. Also generic suspend/resume functions are exported to allow other drivers use them (such as genphy_config_aneg etc.). Within the phy_driver_register function, we need to remove the memset. It overrides the device driver owner and it is not good.

| * netfilter: ctnetlink: deliver events for conntracks changed from userspacePablo Neira Ayuso2008-11-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As for now, the creation and update of conntracks via ctnetlink do not propagate an event to userspace. This can result in inconsistent situations if several userspace processes modify the connection tracking table by means of ctnetlink at the same time. Specifically, using the conntrack command line tool and conntrackd at the same time can trigger unconsistencies. This patch also modifies the event cache infrastructure to pass the process PID and the ECHO flag to nfnetlink_send() to report back to userspace if the process that triggered the change needs so. Based on a suggestion from Patrick McHardy. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net>
| * netfilter: ctnetlink: helper modules load-on-demand supportPablo Neira Ayuso2008-11-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds module loading for helpers via ctnetlink. * Creation path: We support explicit and implicit helper assignation. For the explicit case, we try to load the module. If the module is correctly loaded and the helper is present, we return EAGAIN to re-start the creation. Otherwise, we return EOPNOTSUPP. * Update path: release the spin lock, load the module and check. If it is present, then return EAGAIN to re-start the update. This patch provides a refactorized function to lookup-and-set the connection tracking helper. The function removes the exported symbol __nf_ct_helper_find as it has not clients anymore.

| | | | | | | | | | | | | | | | | | | | This patch modifies xt_NFLOG to suppress the call to nf_log_packet() function.

This is a userspace interface change, but the previous version had not yet been pushed upstream and there are no userspace programs using this yet, so there is justification to get this change in as long as it goes in before the previous version gets out.

This means there is potentially a hidden call in the resume code flow that changes rfkill->state (i.e. rfkill_force_state()), so the previous state of the transmitter was being lost. The simplest and most future-proof way to fix this is to explicitly store the pre-sleep state on the rfkill structure, and restore from that on resume.

We parse the country IEs only on management beacons for the BSSID you are associated to and disregard the IEs when the country and environment (indoor, outdoor, any) matches the already processed country IE. To avoid following misinformed or outdated APs we build and use a regulatory domain out of the intersection between what the AP provides us on the country IE and what CRDA is aware is allowed on the same country. A secondary device is allowed to follow only the same country IE as it make no sense for two devices on a system to be in two different countries. In the case the AP is using country IEs for an incorrect country the user may help compliance further by setting the regulatory domain before or after the IE is parsed and in that case another intersection will be performed. CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA present. Signed-off-by: Luis R.
