Pull networking fixes from David Miller: 1) The value choosen for the new SO_MAX_PACING_RATE socket option on parisc was very poorly choosen, let's fix it while we still can. From Eric Dumazet. 2) Our generic reciprocal divide was found to handle some edge cases incorrectly, part of this is encoded into the BPF as deep as the JIT engines themselves. Just use a real divide throughout for now. From Eric Dumazet. 3) Because the initial lookup is lockless, the TCP metrics engine can end up creating two entries for the same lookup key. Fix this by doing a second lookup under the lock before we actually create the new entry. From Christoph Paasch. 4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork. 5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting. From Dan Carpenter. 6) Netlink socket dumping uses the wrong socket state for timewait sockets. Fix from Neal Cardwell. 7) Fix netlink memory leak in ieee802154_add_iface(), from Christian Engelmayer. 8) Multicast forwarding in ipv4 can overflow the per-rule reference counts, causing all multicast traffic to cease. Fix from Hannes Frederic Sowa. 9) via-rhine needs to stop all TX queues when it resets the device, from Richard Weinberger. 10) Fix RDS per-cpu accesses broken by the this_cpu_* conversions.

Heiko Carstens authored
The s390 bpf jit compiler emits the signed divide instructions "dr" and "d" for unsigned divisions. This can cause problems: the dividend will be zero extended to a 64 bit value and the divisor is the 32 bit signed value as specified A or X accumulator, even though A and X are supposed to be treated as unsigned values. The divide instrunctions will generate an exception if the result cannot be expressed with a 32 bit signed value. This is the case if e.g. the dividend is 0xffffffff and the divisor either 1 or also 0xffffffff (signed: -1). To avoid all these issues simply use unsigned divide instructions.

In commit 1ec047eb ("ipv6: introduce per-interface counter for dad-completed ipv6 addresses") I build the detection of the first operational link-local address much to complex. Additionally this code now has a race condition. Replace it with a much simpler variant, which just scans the address list when duplicate address detection completes, to check if this is the first valid link local address and send RS and MLD reports then.

Christoph Paasch authored
Because the tcp-metrics is an RCU-list, it may be that two soft-interrupts are inside __tcp_get_metrics() for the same destination-IP at the same time. If this destination-IP is not yet part of the tcp-metrics, both soft-interrupts will end up in tcpm_new and create a new entry for this IP. So, we will have two tcp-metrics with the same destination-IP in the list. This patch checks twice __tcp_get_metrics(). First without holding the lock, then while holding the lock. The second one is there to confirm that the entry has not been added by another soft-irq while waiting for the spin-lock. Fixes: 51c5d0c4 (tcp: Maintain dynamic metrics in local cache.)

commit ae4b46e9 "net: rds: use this_cpu_* per-cpu helper" broke per-cpu handling for rds. chpfirst is the result of __this_cpu_read(), so it is an absolute pointer and not __percpu. Therefore, __this_cpu_write() should not operate on chpfirst, but rather on cache->percpu->first, just like __this_cpu_read() did before.

Unfortunately a bad round of colds kept from addressing that in detail until today. The executive summary of the review was: Al: Is patching d_path really sufficient? The prepend_path, d_path, d_absolute_path, and __d_path family of functions is a really mess. Me: Yes, patching d_path is really sufficient. Yes, the code is mess.

Commit 7509963c (e1000e: Fix a compile flag mis-match for suspend/resume) moved suspend and resume hooks to be available when CONFIG_PM is set. However, it can be set even if CONFIG_PM_SLEEP is not set causing following warnings to be emitted: drivers/net/ethernet/intel/e1000e/netdev.c:6178:12: warning: ‘e1000_suspend’ defined but not used [-Wunused-function] drivers/net/ethernet/intel/e1000e/netdev.c:6185:12: warning: ‘e1000_resume’ defined but not used [-Wunused-function] To fix this make the hooks to be available only when CONFIG_PM_SLEEP is set and remove CONFIG_PM wrapping from driver ops because this is already handled by SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS().

On AMD family 10h we see following error messages while waking up from S3 for all non-boot CPUs leading to a failed IBS initialization: Enabling non-boot CPUs ... smpboot: Booting Node 0 Processor 1 APIC 0x1 [Firmware Bug]: cpu 1, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu perf: IBS APIC setup failed on cpu #1 process: Switch to broadcast mode on CPU1 CPU1 is up ... ACPI: Waking up from system sleep state S3 Reason for this is that during suspend the LVT offset for the IBS vector gets lost and needs to be reinialized while resuming. The offset is read from the IBSCTL msr. On family 10h the offset needs to be 1 as offset 0 is used for the MCE threshold interrupt, but firmware assings it for IBS to 0 too. The kernel needs to reprogram the vector. The msr is a readonly node msr, but a new value can be written via pci config space access. The reinitialization is implemented for family 10h in setup_ibs_ctl() which is forced during IBS setup. This patch fixes IBS setup after waking up from S3 by adding resume/supend hooks for the boot cpu which does the offset reinitialization. Marking it as stable to let distros pick up this fix.

The bnx2x driver in its pci shutdown() callback releases its pci bars (in the same manner it does during its pci remove() callback). During a system reboot while VFs are enabled, its possible for the VF's remove to be called (as a result of pci_disable_sriov()) after its shutdown callback has already finished running; This will cause a paging request fault as the VF tries to access the pci bar which it has previously released, crashing the system. This patch further differentiates the shutdown and remove callbacks, preventing the pci release procedures from being called during shutdown.

Commit e66d2ae7 moved the assignment vcpu->arch.apic_base = value above a condition with (vcpu->arch.apic_base ^ value), causing that check to always fail. Use old_value, vcpu->arch.apic_base's old value, in the condition instead. Signed-off-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
