From 8142b227ef43119e19acf6122a9eea1a82492645 Mon Sep 17 00:00:00 2001 From: Andrey Vagin Date: Mon, 31 Mar 2014 18:14:18 +0400 Subject: netfilter: nf_conntrack: flush net_gre->keymap_list only from gre helper nf_ct_gre_keymap_flush() removes a nf_ct_gre_keymap object from net_gre->keymap_list and frees the object. But it doesn't clean a reference on this object from ct_pptp_info->keymap[dir]. Then nf_ct_gre_keymap_destroy() may release the same object again. So nf_ct_gre_keymap_flush() can be called only when we are sure that when nf_ct_gre_keymap_destroy will not be called. nf_ct_gre_keymap is created by nf_ct_gre_keymap_add() and the right way to destroy it is to call nf_ct_gre_keymap_destroy(). This patch marks nf_ct_gre_keymap_flush() as static, so this patch can break compilation of third party modules, which use nf_ct_gre_keymap_flush. I'm not sure this is the right way to deprecate this function.

The other observation is that (on this box) we should never try the PCI reboot method, but close with either the 'triple fault' or the 'BIOS' (terminal!) reboot methods. Thirdly, CF9_COND is a total misnomer - it should be something like CF9_SAFE or CF9_CAREFUL, and 'CF9' should be 'CF9_FORCE' ... So this patch fixes the worst problems: - it orders the actual reboot logic to follow the reboot ordering pattern - it was in a pretty random order before for no good reason. - it fixes the CF9 misnomers and uses BOOT_CF9_FORCE and BOOT_CF9_SAFE flags to make the code more obvious. - it tries the BIOS reboot method before the PCI reboot method. (Since 'BIOS' is a terminal reboot method resulting in a hang if it does not work, this is essentially equivalent to removing the PCI reboot method from the default reboot chain.) - just for the miraculous possibility of terminal (resulting in hang) reboot methods of triple fault or BIOS returning without having done their job, there's an ordering between them as well.

A QSMII interface, as defined at http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface, is "is a method of combining four SGMII lines into a 5Gbit/s interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX data and a single LVDS clock signal. QSGMII uses significantly fewer signal lines than four SGMII busses." This type of MAC <-> PHY connection might require special handling on the MAC driver side, so it should be possible to express this type of MAC <-> PHY connection, for example in the Device Tree.

If there is nothing waiting for these events, it's really kind of pointless to be checking for them. So modify the driver so the message handler can pass down if it needs the lower layer to be waiting for these. Modify the system interface lower layer to turn off all timer and thread activity if the upper layer doesn't need anything and it is not currently handling messages. And modify the message handler to not restart the timer if its timer is not needed. The timers and kthread will still be enabled if: - the SI interface is handling a message. - a user has enabled watching for events. - the IPMI watchdog timer is in use (since it uses pretimeouts). - the message handler is waiting on a remote response. - a user has registered to receive commands. This mostly affects interfaces without interrupts. Interfaces with interrupts already don't use CPU in the system interface when the interface is idle.
