2017-07-12net: stmmac: revert "support future possible different internal phy mode"LABBE Corentin
Since internal phy-mode is reserved for non-xMII protocol we cannot use it with dwmac-sun8i. Furthermore, all DT patchs which comes with this patch were cleaned, so the current state is broken. This reverts commit 1c2fa5f84683 ("net: stmmac: support future possible different internal phy mode") Fixes: 1c2fa5f84683 ("net: stmmac: support future possible different internal phy mode") Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: David S.

2017-07-12sfc: don't read beyond unicast address listBert Kenward
If we have more than 32 unicast MAC addresses assigned to an interface we will read beyond the end of the address table in the driver when adding filters. The next 256 entries store multicast addresses, so we will end up attempting to insert duplicate filters, which is mostly harmless. If we add more than 288 unicast addresses we will then read past the multicast address table, which is likely to be more exciting.

2017-07-12PCI / PM: Restore PME Enable after config space restorationRafael J. Wysocki
Commit dc15e71eefc7 (PCI / PM: Restore PME Enable if skipping wakeup setup) introduced a mechanism by which the PME Enable bit can be restored by pci_enable_wake() if dev->wakeup_prepared is set in case it has been overwritten by PCI config space restoration. However, that commit overlooked the fact that on some systems (Dell XPS13 9360 in particular) the AML handling wakeup events checks PME Status and PME Enable and it won't trigger a Notify() for devices where those bits are not set while it is running. That happens during resume from suspend-to-idle when pci_restore_state() invoked by pci_pm_default_resume_early() clears PME Enable before the wakeup events are processed by AML, effectively causing those wakeup events to be ignored. Fix this issue by restoring the PME Enable configuration right after pci_restore_state() has been called instead of doing that in pci_enable_wake().

2017-07-12Input: i8042 - fix crash at boot timeChen Hong
The driver checks port->exists twice in i8042_interrupt(), first when trying to assign temporary "serio" variable, and second time when deciding whether it should call serio_interrupt(). The value of port->exists may change between the 2 checks, and we may end up calling serio_interrupt() with a NULL pointer: BUG: unable to handle kernel NULL pointer dereference at 0000000000000050 IP: [<ffffffff8150feaf>] _spin_lock_irqsave+0x1f/0x40 PGD 0 Oops: 0002 [#1] SMP last sysfs file: CPU 0 Modules linked in: Pid: 1, comm: swapper Not tainted 2.6.32-358.el6.x86_64 #1 QEMU Standard PC (i440FX + PIIX, 1996) RIP: 0010:[<ffffffff8150feaf>] [<ffffffff8150feaf>] _spin_lock_irqsave+0x1f/0x40 RSP: 0018:ffff880028203cc0 EFLAGS: 00010082 RAX: 0000000000010000 RBX: 0000000000000000 RCX: 0000000000000000 RDX: 0000000000000282 RSI: 0000000000000098 RDI: 0000000000000050 RBP: ffff880028203cc0 R08: ffff88013e79c000 R09: ffff880028203ee0 R10: 0000000000000298 R11: 0000000000000282 R12: 0000000000000050 R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000098 FS: 0000000000000000(0000) GS:ffff880028200000(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 0000000000000050 CR3: 0000000001a85000 CR4: 00000000001407f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process swapper (pid: 1, threadinfo ffff88013e79c000, task ffff88013e79b500) Stack: ffff880028203d00 ffffffff813de186 ffffffffffffff02 0000000000000000 <d> 0000000000000000 0000000000000000 0000000000000000 0000000000000098 <d> ffff880028203d70 ffffffff813e0162 ffff880028203d20 ffffffff8103b8ac Call Trace: <IRQ> [<ffffffff813de186>] serio_interrupt+0x36/0xa0 [<ffffffff813e0162>] i8042_interrupt+0x132/0x3a0 [<ffffffff8103b8ac>] ? kvm_clock_read+0x1c/0x20 [<ffffffff8103b8b9>] ? kvm_clock_get_cycles+0x9/0x10 [<ffffffff810e1640>] handle_IRQ_event+0x60/0x170 [<ffffffff8103b154>] ? kvm_guest_apic_eoi_write+0x44/0x50 [<ffffffff810e3d8e>] handle_edge_irq+0xde/0x180 [<ffffffff8100de89>] handle_irq+0x49/0xa0 [<ffffffff81516c8c>] do_IRQ+0x6c/0xf0 [<ffffffff8100b9d3>] ret_from_intr+0x0/0x11 [<ffffffff81076f63>] ? __do_softirq+0x73/0x1e0 [<ffffffff8109b75b>] ? hrtimer_interrupt+0x14b/0x260 [<ffffffff8100c1cc>] ? call_softirq+0x1c/0x30 [<ffffffff8100de05>] ? do_softirq+0x65/0xa0 [<ffffffff81076d95>] ? irq_exit+0x85/0x90 [<ffffffff81516d80>] ? smp_apic_timer_interrupt+0x70/0x9b [<ffffffff8100bb93>] ? apic_timer_interrupt+0x13/0x20 To avoid the issue let's change the second check to test whether serio is NULL or not.

2017-07-12mlxsw: spectrum_router: Fix use-after-free in route replaceIdo Schimmel
While working on IPv6 route replace I realized we can have a use-after-free in IPv4 in case the replaced route is offloaded and the only one using its FIB info. The problem is that fib_table_insert() drops the reference on the FIB info of the replaced routes which is eventually freed via call_rcu(). Since the driver doesn't hold a reference on this FIB info it can cause a use-after-free when it tries to clear the RTNH_F_OFFLOAD flag stored in fi->fib_flags. After running the following commands in a loop for enough time with a KASAN enabled kernel I finally got the below trace. $ ip route add 192.168.50.0/24 via 192.168.200.1 dev enp3s0np3 $ ip route replace 192.168.50.0/24 dev enp3s0np5 $ ip route del 192.168.50.0/24 dev enp3s0np5 BUG: KASAN: use-after-free in mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] Read of size 4 at addr ffff8803717d9820 by task kworker/u4:2/55 [...] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] ? mlxsw_sp_router_neighs_update_work+0x1cd0/0x1ce0 [mlxsw_spectrum] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] __asan_load4+0x61/0x80 mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] mlxsw_sp_fib_entry_offload_refresh+0xb6/0x370 [mlxsw_spectrum] mlxsw_sp_router_fib_event_work+0xd1c/0x2780 [mlxsw_spectrum] [...] Freed by task 5131: save_stack_trace+0x16/0x20 save_stack+0x46/0xd0 kasan_slab_free+0x70/0xc0 kfree+0x144/0x570 free_fib_info_rcu+0x2e7/0x410 rcu_process_callbacks+0x4f8/0xe30 __do_softirq+0x1d3/0x9e2 Fix this by taking a reference on the FIB info when creating the nexthop group it represents and drop it when the group is destroyed.

2017-07-12cpufreq: intel_pstate: Fix ratio setting for min_perf_pctSrinivas Pandruvada
When the minimum performance limit percentage is set to the power-up default, it is possible that minimum performance ratio is off by one. In the set_policy() callback the minimum ratio is calculated by applying global.min_perf_pct to turbo_ratio and rounding up, but the power-up default global.min_perf_pct is already rounded up to the next percent in min_perf_pct_min(). That results in two round up operations, so for the default min_perf_pct one of them is not required. It is better to remove rounding up in min_perf_pct_min() as this matches the displayed min_perf_pct prior to commit c5a2ee7dde89 (cpufreq: intel_pstate: Active mode P-state limits rework) in 4.12. For example on a platform with max turbo ratio of 37 and minimum ratio of 10, the min_perf_pct resulted in 28 with the above commit. Before this commit it was 27 and it will be the same after this change.

On one such system the device is even hidden until a certain time after _SB.PCI0.GFX0.LCD.LCD1._ON gets called has passed *and* _STA has been called at least 3 times since. TL;DR: it is a mess. Until now the always_present_id matching was used to force status for a whole class of devices, e.g. always enable PWM1 on CHerry Trail devices. This commit extends the always_present_id matching code to optionally also check for a DMI match so that we can also add system specific quirks to the always_present_id array.

2017-07-12Revert "ACPI / EC: Enable event freeze mode..." to fix a regressionLv Zheng
On Lenovo ThinkPad X1 Carbon - the 5th Generation, enabling an earlier EC event freezing timing causes acpitz-virtual-0 to report a stuck 48C temparature. And with EC firmware revisioned as 1.14, without reverting back to old EC event freezing timing, the fan still blows up after a system resume. This reverts the culprit change so that the regression can be fixed without upgrading the EC firmware.

2017-07-12ACPI / EC: Drop EC noirq hooks to fix a regressionLv Zheng
According to bug reports, although the busy polling mode can make noirq stages execute faster, it causes abnormal fan blowing up after system resume (see the first link below for a video demonstration) on Lenovo ThinkPad X1 Carbon - the 5th Generation. The problem can be fixed by upgrading the EC firmware on that machine. However, many reporters confirm that the problem can be fixed by stopping busy polling during suspend/resume and for some of them upgrading the EC firmware is not an option. For this reason, drop the noirq stage hooks from the EC driver to fix the regression.

2017-07-12crypto: caam - properly set IV after {en,de}cryptDavid Gstir
Certain cipher modes like CTS expect the IV (req->info) of ablkcipher_request (or equivalently req->iv of skcipher_request) to contain the last ciphertext block when the {en,de}crypt operation is done. This is currently not the case for the CAAM driver which in turn breaks e.g. cts(cbc(aes)) when the CAAM driver is enabled. This patch fixes the CAAM driver to properly set the IV after the {en,de}crypt operation of ablkcipher finishes.

Driver does not properly handle the case when signals interrupt wait_for_completion_interruptible(): -it does not check for return value -completion structure is allocated on stack; in case a signal interrupts the sleep, it will go out of scope, causing the worker thread (caam_jr_dequeue) to fail when it accesses it wait_for_completion_interruptible() is replaced with uninterruptable wait_for_completion(). We choose to block all signals while waiting for I/O (device executing the split key generation job descriptor) since the alternative - in order to have a deterministic device state - would be to flush the job ring (aborting *all* in-progress jobs).

2017-07-11cxgb4: fix BUG() on interrupt deallocating path of ULDGuilherme G. Piccoli
Since the introduction of ULD (Upper-Layer Drivers), the MSI-X deallocating path changed in cxgb4: the driver frees the interrupts of ULD when unregistering it or on shutdown PCI handler. Problem is that if a MSI-X is not freed before deallocated in the PCI layer, it will trigger a BUG() due to still "alive" interrupt being tentatively quiesced.

This patch re-introduces part of a long standing login workaround that was recently dropped by: commit 1c99de981f30b3e7868b8d20ce5479fa1c0fea46 Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Sun Apr 2 13:36:44 2017 -0700 iscsi-target: Drop work-around for legacy GlobalSAN initiator Namely, the workaround for FirstBurstLength ended up being required by Mellanox Flexboot PXE boot ROMs as reported by Robert. So this patch re-adds the work-around for FirstBurstLength within iscsi_check_proposer_for_optional_reply(), and makes the key optional to respond when the initiator does not propose, nor respond to it. Also as requested by Arun, this patch introduces a new TPG attribute named 'login_keys_workaround' that controls the use of both the FirstBurstLength workaround, as well as the two other existing workarounds for gPXE iSCSI boot client. By default, the workaround is enabled with login_keys_workaround=1, since Mellanox FlexBoot requires it, and Arun has verified the Qlogic MSFT initiator already proposes FirstBurstLength, so it's uneffected by this re-adding this part of the original work-around.
