Fix inet_diag_dump_icsk() to reflect the fact that both TCP_TIME_WAIT and TCP_FIN_WAIT2 connections are represented by inet_timewait_sock (not just TIME_WAIT), and for such sockets the tw_substate field holds the real state, which can be either TCP_TIME_WAIT or TCP_FIN_WAIT2. This brings the inet_diag state-matching code in line with the field it uses to populate idiag_state. This is also analogous to the info exported in /proc/net/tcp, where get_tcp4_sock() exports sk->sk_state and get_timewait4_sock() exports tw->tw_substate. Before fixing this, (a) neither "ss -nemoi" nor "ss -nemoi state fin-wait-2" would return a socket in TCP_FIN_WAIT2; and (b) "ss -nemoi state time-wait" would also return sockets in state TCP_FIN_WAIT2. This is an old bug that predates 05dbc7b5 ("tcp/dccp: remove twchain"). Signed-off-by:

Pull ACPI and power management fixes from Rafael Wysocki: - Recent commits modifying the lists of C-states in the intel_idle driver introduced bugs leading to crashes on some systems. Two fixes from Jiang Liu. - The ACPI AC driver should receive all types of notifications, but recent change made it ignore some of them. Fix from Alexander Mezin. - intel_pstate's validity checks for MSRs it depends on are not sufficient to catch the lack of support in nested KVM setups, so they are extended to cover that case. From Dirk Brandewie. - NEC LZ750/LS has a botched up _BIX method in its ACPI tables, so our ACPI battery driver needs a quirk for it.

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

L2 fowarding offload will bypass the rx handler of real device. This will make the packet could not be forwarded to macvtap device. Another problem is the dev_hard_start_xmit() called for macvtap does not have any synchronization. Fix this by forbidding L2 forwarding for macvtap.

In the past the IFA_PERMANENT flag indicated, that the valid and preferred lifetime where ignored. Since change fad8da3e ("ipv6 addrconf: fix preferred lifetime state-changing behavior while valid_lft is infinity") we honour at least the preferred lifetime on those addresses. As such the valid lifetime gets recalculated and updated to 0. If loopback address is added manually this problem does not occur. Also if NetworkManager manages IPv6, those addresses will get added via inet6_rtm_newaddr and thus will have a correct lifetime, too. Reported-by:

Helge Deller noted a few weeks ago problems with the AIO support on parisc. This change is the result of numerous iterations on how best to deal with this problem. The solution adopted here is to provide full cache coherency in a uniform manner on all parisc systems. This involves calling flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on kunmap operations. As a result, the copy_user_page() and clear_user_page() functions can be removed and the overall code is simpler. The change ensures that both userspace and kernel aliases to a mapped page are invalidated and flushed. This is necessary for the correct operation of PA8800 and PA8900 based systems which do not support inequivalent aliases. With this change, I have observed no cache related issues on c8000 and rp3440. It is now possible for example to do kernel builds with "-j64" on four way systems. On systems using XFS file systems, the patch recently posted by Mikulas Patocka to "fix crash using XFS on loopback" is needed to avoid a hang caused by an uninitialized lock passed to flush_dcache_page() in the page struct.

Commit 6d9252bd (clk: Add support for power of two type dividers) merged in v3.6 added the _get_val function to convert a divisor value to a register field value depending on the flags. However it used the type u8 for the div field, causing divisors larger than 255 to be masked and the resultant clock rate to be too high. E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This was masked to 238 (0xee) resulting in a frequency of 103.26KHz. Signed-off-by:

The only BIOS on record that needs the 14 offset has a bios major version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18 offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the bios major version, look at the BMP version. BIOSes with BMP version 0 do not contain a detectable script, so always return 0 for them.

When we pull a received packet from a link's 'deferred packets' queue for processing, its 'next' pointer is not cleared, and still refers to the next packet in that queue, if any. This is incorrect, but caused no harm before commit 40ba3cdf ("tipc: message reassembly using fragment chain") was introduced. After that commit, it may sometimes lead to the following oops: general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC Modules linked in: tipc CPU: 4 PID: 0 Comm: swapper/4 Tainted: G W 3.13.0-rc2+ #6 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2007 task: ffff880017af4880 ti: ffff880017aee000 task.ti: ffff880017aee000 RIP: 0010:[<ffffffff81710694>] [<ffffffff81710694>] skb_try_coalesce+0x44/0x3d0 RSP: 0018:ffff880016603a78 EFLAGS: 00010212 RAX: 6b6b6b6bd6d6d6d6 RBX: ffff880013106ac0 RCX: ffff880016603ad0 RDX: ffff880016603ad7 RSI: ffff88001223ed00 RDI: ffff880013106ac0 RBP: ffff880016603ab8 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000001 R11: 0000000000000000 R12: ffff88001223ed00 R13: ffff880016603ad0 R14: 000000000000058c R15: ffff880012297650 FS: 0000000000000000(0000) GS:ffff880016600000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 000000000805b000 CR3: 0000000011f5d000 CR4: 00000000000006e0 Stack: ffff880016603a88 ffffffff810a38ed ffff880016603aa8 ffff88001223ed00 0000000000000001 ffff880012297648 ffff880016603b68 ffff880012297650 ffff880016603b08 ffffffffa0006c51 ffff880016603b08 00ffffffa00005fc Call Trace: <IRQ> [<ffffffff810a38ed>] ? trace_hardirqs_on+0xd/0x10 [<ffffffffa0006c51>] tipc_link_recv_fragment+0xd1/0x1b0 [tipc] [<ffffffffa0007214>] tipc_recv_msg+0x4e4/0x920 [tipc] [<ffffffffa00016f0>] ? tipc_l2_rcv_msg+0x40/0x250 [tipc] [<ffffffffa000177c>] tipc_l2_rcv_msg+0xcc/0x250 [tipc] [<ffffffffa00016f0>] ? tipc_l2_rcv_msg+0x40/0x250 [tipc] [<ffffffff8171e65b>] __netif_receive_skb_core+0x80b/0xd00 [<ffffffff8171df94>] ? __netif_receive_skb_core+0x144/0xd00 [<ffffffff8171eb76>] __netif_receive_skb+0x26/0x70 [<ffffffff8171ed6d>] netif_receive_skb+0x2d/0x200 [<ffffffff8171fe70>] napi_gro_receive+0xb0/0x130 [<ffffffff815647c2>] e1000_clean_rx_irq+0x2c2/0x530 [<ffffffff81565986>] e1000_clean+0x266/0x9c0 [<ffffffff81985f7b>] ? notifier_call_chain+0x2b/0x160 [<ffffffff8171f971>] net_rx_action+0x141/0x310 [<ffffffff81051c1b>] __do_softirq+0xeb/0x480 [<ffffffff819817bb>] ? _raw_spin_unlock+0x2b/0x40 [<ffffffff810b8c42>] ? handle_fasteoi_irq+0x72/0x100 [<ffffffff81052346>] irq_exit+0x96/0xc0 [<ffffffff8198cbc3>] do_IRQ+0x63/0xe0 [<ffffffff81981def>] common_interrupt+0x6f/0x6f <EOI> This happens when the last fragment of a message has passed through the the receiving link's 'deferred packets' queue, and at least one other packet was added to that queue while it was there. After the fragment chain with the complete message has been successfully delivered to the receiving socket, it is released. Since 'next' pointer of the last fragment in the released chain now is non-NULL, we get the crash shown above. We fix this by clearing the 'next' pointer of all received packets, including those being pulled from the 'deferred' queue, before they undergo any further processing.

Jani for co-maintainer! Jani has been a really active bug-scrubber in the past few months. I've asked him whether he wants to do this in a more official capacity and he agreed. I've already chatted with Dave and Jesse and they support this. Note that everyone can't now just relax because "Jani will do all the bug scrubbing" - au contraire expect more nagging and poking now that we have more bandwidth. Longer-term the plan is to share more of the maintainer duties, but we need to fix up the infrastructure a bit first (like moving the git repo to a common location). While at it also add the newly set-up patchwork instance. Cc: Dave Airlie <airlied@gmail.com> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: Jani Nikula <jani.nikula@linux.intel.com> Signed-off-by:

This fixes a hang in VBIOS scripts of the form "condition; jump". The jump used to always be executed, while now it will only be executed if the condition is true. See https://bugs.freedesktop.org/show_bug.cgi?id=72943Reported-by:
