From: Patrick McHardy <kaber@trash.net> Just as a demonstration how easy adding a peek operation to the work-conserving qdiscs actually is. It doesn't need to keep or change any internal state in many cases thanks to the guarantee that the packet will either be dequeued or, if another packet arrives, the upper qdisc will immediately ->peek again to reevaluate the state. (This is only slightly modified Patrick's patch.) Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

I noticed that, under certain conditions, ESRCH can be leaked from the xfrm layer to user space through sys_connect. In particular, this seems to happen reliably when the kernel fails to resolve a template either because the AF_KEY receive buffer being used by racoon is full or because the SA entry we are trying to use is in XFRM_STATE_EXPIRED state. However, since this could be a transient issue it could be argued that EAGAIN would be more appropriate. Besides this error code is not even documented in the man page for sys_connect (as of man-pages 3.07). Signed-off-by: Fernando Luis Vazquez Cao <fernando@oss.ntt.co.jp> Signed-off-by: David S.

register_pernet_gen_device() can't be used is nf_conntrack_pptp module is also used (compiled in or loaded). Right now, proto_gre_net_exit() is called before nf_conntrack_pptp_net_exit(). The former shutdowns and frees GRE piece of netns, however the latter absolutely needs it to flush keymap. Oops is inevitable. Switch to shiny new register_pernet_gen_subsys() to get correct ordering in netns ops list.

netns ops which are registered with register_pernet_gen_device() are shutdown strictly before those which are registered with register_pernet_subsys(). Sometimes this leads to opposite (read: buggy) shutdown ordering between two modules. Add register_pernet_gen_subsys()/unregister_pernet_gen_subsys() for modules which aren't elite enough for entry in struct net, and which can't use register_pernet_gen_device(). PPTP conntracking module is such one. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

The link may be up already via the chip's reset strapping, or though action of U-Boot, or from the last time the interface was brought up. Resetting the link causes it to go down for several seconds. This can significantly increase the time from power-on to DHCP completion and a device being accessible to the network.

The init_phy() function attaches to the PHY, then configures the SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

A panic was discovered with bonding when using mode 5 or 6 and trying to remove the slaves from the bond after the interface was taken down. When calling 'ifconfig bond0 down' the following happens: bond_close() bond_alb_deinitialize() tlb_deinitialize() kfree(bond_info->tx_hashtbl) bond_info->tx_hashtbl = NULL Unfortunately if there are still slaves in the bond, when removing the module the following happens: bonding_exit() bond_free_all() bond_release_all() bond_alb_deinit_slave() tlb_clear_slave() tx_hash_table = BOND_ALB_INFO(bond).tx_hashtbl u32 next_index = tx_hash_table[index].next As you might guess we panic when trying to access a few entries into the table that no longer exists. I experimented with several options (like moving the calls to tlb_deinitialize somewhere else), but it really makes the most sense to be part of the bond_close routine. It also didn't seem logical move tlb_clear_slave around too much, so the simplest option seems to add a check in tlb_clear_slave to make sure we haven't already wiped the tx_hashtbl away before searching for all the non-existent hash-table entries that used to point to the slave as the output interface.

This patch reworks the resource free logic performed at the time a bonding device is released. This (a) closes two resource leaks, one for workqueues and one for multicast lists, and (b) improves commonality of code between the "destroy one" and "destroy all" paths by performing final free activity via destructor instead of explicitly (and differently) in each path. "Sean E. Millichamp" <sean@bruenor.org> reported the workqueue leak, and included a different patch. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
