* drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker2015-06-2364-268/+94
| | | | | | | | | | | | | | | | | | This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * net: stmmac: dwmac-rk: abstract access to mac settings in GRFHeiko Stübner2015-06-231-41/+75
| | | | | | | | | | | | | | | | | | | | | | The mac settings like RGMII/RMII, speeds etc are done in the so called "General Register Files", contain numerous other settings as well and always seem to change between Rockchip SoCs. Therefore abstract the register accesses into a per-soc ops struct to make this reusable on other Rockchip SoCs. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: David S.

| * net: stmmac: dwmac-rk: Fix clk rate when provided by socHeiko Stübner2015-06-231-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first iteration of the dwmac-rk support did access an intermediate clock directly below the pll selector. This was removed in a subsequent revision, but the clock and one invocation remained. This results in the driver trying to set the rate of a non-existent clock when the soc and not some external source provides the phy clock for RMII phys. So set the rate of the correct clock and remove the remaining now completely unused definition.

* netfilter: nf_qeueue: Drop queue entries on nf_unregister_hookEric W. Biederman2015-06-235-1/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add code to nf_unregister_hook to flush the nf_queue when a hook is unregistered. This guarantees that the pointer that the nf_queue code retains into the nf_hook list will remain valid while a packet is queued. I tested what would happen if we do not flush queued packets and was trivially able to obtain the oops below. All that was required was to stop the nf_queue listening process, to delete all of the nf_tables, and to awaken the nf_queue listening process. > BUG: unable to handle kernel paging request at 0000000100000001 > IP: [<0000000100000001>] 0x100000001 > PGD b9c35067 PUD 0 > Oops: 0010 [#1] SMP > Modules linked in: > CPU: 0 PID: 519 Comm: lt-nfqnl_test Not tainted > task: ffff8800b9c8c050 ti: ffff8800ba9d8000 task.ti: ffff8800ba9d8000 > RIP: 0010:[<0000000100000001>] [<0000000100000001>] 0x100000001 > RSP: 0018:ffff8800ba9dba40 EFLAGS: 00010a16 > RAX: ffff8800bab48a00 RBX: ffff8800ba9dba90 RCX: ffff8800ba9dba90 > RDX: ffff8800b9c10128 RSI: ffff8800ba940900 RDI: ffff8800bab48a00 > RBP: ffff8800b9c10128 R08: ffffffff82976660 R09: ffff8800ba9dbb28 > R10: dead000000100100 R11: dead000000200200 R12: ffff8800ba940900 > R13: ffffffff8313fd50 R14: ffff8800b9c95200 R15: 0000000000000000 > FS: 00007fb91fc34700(0000) GS:ffff8800bfa00000(0000) knlGS:0000000000000000 > CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 > CR2: 0000000100000001 CR3: 00000000babfb000 CR4: 00000000000007f0 > Stack: > ffffffff8206ab0f ffffffff82982240 ffff8800bab48a00 ffff8800b9c100a8 > ffff8800b9c10100 0000000000000001 ffff8800ba940900 ffff8800b9c10128 > ffffffff8206bd65 ffff8800bfb0d5e0 ffff8800bab48a00 0000000000014dc0 > Call Trace: > [<ffffffff8206ab0f>] ? nf_iterate+0x4f/0xa0 > [<ffffffff8206bd65>] ? nf_reinject+0x125/0x190 > [<ffffffff8206dee5>] ? nfqnl_recv_verdict+0x255/0x360 > [<ffffffff81386290>] ? nla_parse+0x80/0xf0 > [<ffffffff8206c42c>] ? nfnetlink_rcv_msg+0x13c/0x240 > [<ffffffff811b2fec>] ? __memcg_kmem_get_cache+0x4c/0x150 > [<ffffffff8206c2f0>] ? nfnl_lock+0x20/0x20 > [<ffffffff82068159>] ? netlink_rcv_skb+0xa9/0xc0 > [<ffffffff820677bf>] ? netlink_unicast+0x12f/0x1c0 > [<ffffffff82067ade>] ? netlink_sendmsg+0x28e/0x650 > [<ffffffff81fdd814>] ? sock_sendmsg+0x44/0x50 > [<ffffffff81fde07b>] ? ___sys_sendmsg+0x2ab/0x2c0 > [<ffffffff810e8f73>] ? __wake_up+0x43/0x70 > [<ffffffff8141a134>] ? tty_write+0x1c4/0x2a0 > [<ffffffff81fde9f4>] ? __sys_sendmsg+0x44/0x80 > [<ffffffff823ff8d7>] ? system_call_fastpath+0x12/0x6a > Code: Bad RIP value. > RIP [<0000000100000001>] 0x100000001 > RSP <ffff8800ba9dba40> > CR2: 0000000100000001 > ---[ end trace 08eb65d42362793f ]--- Cc: stable@vger.kernel.org Signed-off-by: "Eric W.

We attach kprobes at trace_preempt_off and trace_preempt_on and calculate the time it takes to from seeing the off/on transition. The first array is used to store the start time stamp. The key is the CPU id. The second array stores the log2(time diff). We need to use static allocation here (array and not hash tables). The kprobes hooking into trace_preempt_on|off should not calling any dynamic memory allocation or free path. We need to avoid recursivly getting called. Besides that, it reduces jitter in the measurement.

* bridge: multicast: start querier timer when running user-space stpNikolay Aleksandrov2015-06-231-1/+2
| | | | | | | | | | | | | When STP is running in user-space and querier is configured, the querier timer is not started when a port goes to a non-blocking state. This patch unifies the user- and kernel-space stp multicast port enable path and enables it in all states different from blocking. Note that when a port goes in BR_STATE_DISABLED it's not enabled because that is handled in the beginning of the port list loop.

Notably, when passing in 0x00 as an instance identifier to signal that all instances should be removed then the mgmt API would return a hard coded 0x01 rather than returning the expected value 0x00. This bug is being fixed by always referencing the instance identifier from the management API call instead. remove_advertising() is refactored to use the new dynamic advertising instance list. The logic is being changed to make multi-instance advertising actually work, notably the schedule_adv_instance() method is being referenced to make sure that other instances will continue to advertise even if one instance is being removed. The code is made more readable by factoring advertising instance management and initialization into the low-level hci_remove_adv_instance() and hci_adv_instances_clear() functions. The method now references the clear_adv_instance() helper method to remove duplicate logic and code.

Both methods are being refactored to access the dynamic advertising instance list instead. This patch also introduces all logic necessary to actually deal with multiple instance advertising. Notably the mgmt_adv_inst_expired() and schedule_adv_inst() method are being referenced to schedule instances in a round robin fashion. This patch also introduces a "pending" flag into the adv_info struct. This is necessary to identify and remove recently added advertising instances when the HCI commands return with an error status code. Otherwise new advertising instances could be leaked without properly informing userspace about their existence.

It is being changed to provide both, a means to clean up a single instance and cleaning up all instances at once. An additional instance parameter is being introduced to achieve this. Passing in 0x00 to this parameter signifies that all instances should be cleaned up. This semantics has been chosen similarly to the semantics of the instance parameter in the remove_advertising() function. When removing a single instance the method also ensures that another instance will be scheduled if available. When the currently advertising method is being removed, it will be canceled immediately.
