Pull ARM fix from Russell King: "Just a single fix this time around for recent binutils causing build problems when generating Thumb-2 code" * 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8781/1: Fix Thumb-2 syscall return for binutils 2.29+
2018-08-01mm: do not initialize TLB stack vma's with vma_init()Linus Torvalds1-4/+1
Commit 2c4541e24c55 ("mm: use vma_init() to initialize VMAs on stack and data segments") tried to initialize various left-over ad-hoc vma's "properly", but actually made things worse for the temporary vma's used for TLB flushing. vma_init() doesn't actually initialize all of the vma, just a few fields, so doing something like - struct vm_area_struct vma = { .vm_mm = tlb->mm, }; + struct vm_area_struct vma; + + vma_init(&vma, tlb->mm); was actually very bad: instead of having a nicely initialized vma with every field but "vm_mm" zeroed, you'd have an entirely uninitialized vma with only a couple of fields initialized. And they weren't even fields that the code in question mostly cared about. The flush_tlb_range() function takes a "struct vma" rather than a "struct mm_struct", because a few architectures actually care about what kind of range it is - being able to only do an ITLB flush if it's a range that doesn't have data accesses enabled, for example. And all the normal users already have the vma for doing the range invalidation. But a few people want to call flush_tlb_range() with a range they just made up, so they also end up using a made-up vma. x86 just has a special "flush_tlb_mm_range()" function for this, but other architectures (arm and ia64) do the "use fake vma" thing instead, and thus got caught up in the vma_init() changes. At the same time, the TLB flushing code really doesn't care about most other fields in the vma, so vma_init() is just unnecessary and pointless. This fixes things by having an explicit "this is just an initializer for the TLB flush" initializer macro, which is used by the arm/arm64/ia64 people who mis-use this interface with just a dummy vma.

2018-07-30ARM: 8781/1: Fix Thumb-2 syscall return for binutils 2.29+Vincent Whitchurch1-1/+3
When building the kernel as Thumb-2 with binutils 2.29 or newer, if the assembler has seen the .type directive (via ENDPROC()) for a symbol, it automatically handles the setting of the lowest bit when the symbol is used with ADR. The badr macro on the other hand handles this lowest bit manually. This leads to a jump to a wrong address in the wrong state in the syscall return path: Internal error: Oops - undefined instruction: 0 [#2] SMP THUMB2 Modules linked in: CPU: 0 PID: 652 Comm: modprobe Tainted: G D 4.18.0-rc3+ #8 PC is at ret_fast_syscall+0x4/0x62 LR is at sys_brk+0x109/0x128 pc : [<80101004>] lr : [<801c8a35>] psr: 60000013 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 50c5387d Table: 9e82006a DAC: 00000051 Process modprobe (pid: 652, stack limit = 0x(ptrval)) 80101000 <ret_fast_syscall>: 80101000: b672 cpsid i 80101002: f8d9 2008 ldr.w r2, [r9, #8] 80101006: f1b2 4ffe cmp.w r2, #2130706432 ; 0x7f000000 80101184 <local_restart>: 80101184: f8d9 a000 ldr.w sl, [r9] 80101188: e92d 0030 stmdb sp!, {r4, r5} 8010118c: f01a 0ff0 tst.w sl, #240 ; 0xf0 80101190: d117 bne.n 801011c2 <__sys_trace> 80101192: 46ba mov sl, r7 80101194: f5ba 7fc8 cmp.w sl, #400 ; 0x190 80101198: bf28 it cs 8010119a: f04f 0a00 movcs.w sl, #0 8010119e: f3af 8014 nop.w {20} 801011a2: f2af 1ea2 subw lr, pc, #418 ; 0x1a2 To fix this, add a new symbol name which doesn't have ENDPROC used on it and use that with badr.

2018-07-20ARM: dts: imx6: RDU2: fix irq type for mv88e6xxx switchUwe Kleine-König1-1/+1
The Marvell switches report their interrupts in a level sensitive way. When using edge sensitive detection a race condition in the interrupt handler of the swich might result in the OS to miss all future events which might make the switch non-functional. The problem is that both mv88e6xxx_g2_irq_thread_fn() and mv88e6xxx_g1_irq_thread_work() sample the irq cause register (MV88E6XXX_G2_INT_SRC and MV88E6XXX_G1_STS respectively) once and then handle the observed sources. If after sampling but before all observed irq sources are handled a new irq source gets active this is not noticed by the handler which returns unsuspecting, but the interrupt line stays active which prevents the edge detector to kick in. All device trees but imx6qdl-zii-rdu2 get this right (most of them by not specifying an interrupt parent). So fix imx6qdl-zii-rdu2 accordingly.

Call secure services to enable ACTLR[0] (Enable invalidates of BTB with ICIALLU) when branch hardening is enabled for kernel. On GP devices OMAP5/DRA7, there is no possibility to update secure side since "secure world" is ROM and there are no override mechanisms possible. On HS devices, appropriate PPA should do the workarounds as well. However, the configuration is only done for secondary core, since it is expected that firmware/bootloader will have enabled the required configuration for the primary boot core (note: bootloaders typically will NOT enable secondary processors, since it has no need to do so).

2018-07-11ARM: 8780/1: ftrace: Only set kernel memory back to read-only after bootSteven Rostedt (VMware)1-0/+9
Dynamic ftrace requires modifying the code segments that are usually set to read-only. To do this, a per arch function is called both before and after the ftrace modifications are performed. The "before" function will set kernel code text to read-write to allow for ftrace to make the modifications, and the "after" function will set the kernel code text back to "read-only" to keep the kernel code text protected. The issue happens when dynamic ftrace is tested at boot up. The test is done before the kernel code text has been set to read-only. But the "before" and "after" calls are still performed. The "after" call will change the kernel code text to read-only prematurely, and other boot code that expects this code to be read-write will fail. The solution is to add a variable that is set when the kernel code text is expected to be converted to read-only, and make the ftrace "before" and "after" calls do nothing if that variable is not yet set. This is similar to the x86 solution from commit 162396309745 ("ftrace, x86: make kernel text writable only for conversions").

Daniel Borkmann says: ==================== pull-request: bpf 2018-07-01 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) A bpf_fib_lookup() helper fix to change the API before freeze to return an encoding of the FIB lookup result and return the nexthop device index in the params struct (instead of device index as return code that we had before), from David. 2) Various BPF JIT fixes to address syzkaller fallout, that is, do not reject progs when set_memory_*() fails since it could still be RO. Also arm32 JIT was not using bpf_jit_binary_lock_ro() API which was an issue, and a memory leak in s390 JIT found during review, from Daniel. 3) Multiple fixes for sockmap/hash to address most of the syzkaller triggered bugs. Usage with IPv6 was crashing, a GPF in bpf_tcp_close(), a missing sock_map_release() routine to hook up to callbacks, and a fix for an omitted bucket lock in sock_close(), from John. 4) Two bpftool fixes to remove duplicated error message on program load, and another one to close the libbpf object after program load. One additional fix for nfp driver's BPF offload to avoid stopping offload completely if replace of program failed, from Jakub. 5) Couple of BPF selftest fixes that bail out in some of the test scripts if the user does not have the right privileges, from Jeffrin. 6) Fixes in test_bpf for s390 when CONFIG_BPF_JIT_ALWAYS_ON is set where we need to set the flag that some of the test cases are expected to fail, from Kleber. 7) Fix to detangle BPF_LIRC_MODE2 dependency from CONFIG_CGROUP_BPF since it has no relation to it and lirc2 users often have configs without cgroups enabled and thus would not be able to use it, from Sean. 8) Fix a selftest failure in sockmap by removing a useless setrlimit() call that would set a too low limit where at the same time we are already including bpf_rlimit.h that does the job, from Yonghong. 9) Fix BPF selftest config with missing missing NET_SCHED, from Anders. ==================== Signed-off-by: David S.

2018-06-26PCI: controller: Move PCI_DOMAINS selection to arch KconfigLorenzo Pieralisi3-1/+9
Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage") added configuration options to allow PCI host controller drivers to be compile tested on all architectures. Some host controller drivers (eg PCIE_ALTERA) config entries select the PCI_DOMAINS config option to enable PCI domains management in the kernel. Now that host controller drivers can be compiled on all architectures, this triggers build regressions on arches that do not implement the PCI_DOMAINS required API (ie pci_domain_nr()): drivers/ata/pata_ali.c: In function 'ali_init_chipset': drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'? Furthemore, some software configurations (ie Jailhouse) require a PCI_DOMAINS enabled kernel to configure multiple host controllers without having an explicit dependency on the ARM platform on which they run. Make PCI_DOMAINS a visible configuration option on ARM so that software configurations that need it can manually select it and move the PCI_DOMAINS selection from PCI controllers configuration file to ARM sub-arch config entries that currently require it, fixing the issue.
