2015-05-31um: Create asm/sections.hNicolas Iooss5-7/+11
arch/um/kernel/dyn.lds.S and arch/um/kernel/uml.lds.S define some UML-specific symbols. These symbols are used in the kernel part of UML with extern declarations. Move these declarations to a new header, asm/sections.h, like other architectures do. Signed-off-by: Nicolas Iooss <nicolas.iooss_linux@m4x.org> Signed-off-by: Richard Weinberger <richard@nod.at>

Pull networking fixes from David Miller: 1) Don't leak ipvs->sysctl_tbl, from Tommi Rentala. 2) Fix neighbour table entry leak in rocker driver, from Ying Xue. 3) Do not emit bonding notifications for unregistered interfaces, from Nicolas Dichtel. 4) Set ipv6 flow label properly when in TIME_WAIT state, from Florent Fourcot. 5) Fix regression in ipv6 multicast filter test, from Henning Rogge. 6) do_replace() in various footables netfilter modules is missing a check for 0 counters in the datastructure provided by the user. Fix from Dave Jones, and found with trinity. 7) Fix RCU bug in packet scheduler classifier module unloads, from Daniel Borkmann. 8) Avoid deadlock in tcp_get_info() by using u64_sync. From Eric Dumzaet. 9) Input packet processing can race with inetdev_destroy() teardown, fix potential OOPS in ip_error() by explicitly testing whether the inetdev is still attached. From Eric W Biederman. 10) MLDv2 parser in bridge multicast code breaks too early while parsing. Fix from Thadeu Lima de Souza Cascardo. 11) Asking for settings on non-zero PHYID doesn't work because we do not import the command structure from the user and use the PHYID provided there. Fix from Arun Parameswaran. 12) Fix UDP checksums with IPV6 RAW sockets, from Vlad Yasevich. 13) Missing NF_TABLES depends for TPROXY etc can cause build failures, fix from Florian Westphal. 14) Fix netfilter conntrack to handle RFC5961 challenge ACKs properly, from Jesper Dangaard Brouer. 15) If netlink autobind retry fails, we have to reset the sockets portid back to zero. From Herbert Xu. 16) VXLAN netns exit code unregisters using wrong device, from John W Linville. 17) Add some USB device IDs to ath3k and btusb bluetooth drivers, from Dmitry Tunin and Wen-chien Jesse Sung. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (44 commits) bridge: fix lockdep splat net: core: 'ethtool' issue with querying phy settings bridge: fix parsing of MLDv2 reports ARM: zynq: DT: Use the zynq binding with macb net: macb: Disable half duplex gigabit on Zynq net: macb: Document zynq gem dt binding ipv4: fill in table id when replacing a route cdc_ncm: Fix tx_bytes statistics ipv4: Avoid crashing in ip_error tcp: fix a potential deadlock in tcp_get_info() net: sched: fix call_rcu() race on classifier module unloads net: phy: Make sure phy_start() always re-enables the phy interrupts ipv6: fix ECMP route replacement ipv6: do not delete previously existing ECMP routes if add fails Revert "netfilter: bridge: query conntrack about skb dnat" netfilter: ensure number of counters is >0 in do_replace() netfilter: nfnetlink_{log,queue}: Register pernet in first place tcp: don't over-send F-RTO probes tcp: only undo on partial ACKs in CA_Loss net/ipv6/udp: Fix ipv6 multicast socket filter regression ...

2015-05-14ARM: EXYNOS: Fix failed second suspend on Exynos4Krzysztof Kozlowski4-37/+34
On Exynos4412 boards (Trats2, Odroid U3) after enabling L2 cache in 56b60b8bce4a ("ARM: 8265/1: dts: exynos4: Add nodes for L2 cache controller") the second suspend to RAM failed. First suspend worked fine but the next one hang just after powering down of secondary CPUs (system consumed energy as it would be running but was not responsive). The issue was caused by enabling delayed reset assertion for CPU0 just after issuing power down of cores. This was introduced for Exynos4 in 13cfa6c4f7fa ("ARM: EXYNOS: Fix CPU idle clock down after CPU off"). The whole behavior is not well documented but after checking with vendor code this should be done like this (on Exynos4): 1. Enable delayed reset assertion when system is running (for all CPUs). 2. Disable delayed reset assertion before suspending the system. This can be done after powering off secondary CPUs. 3. Re-enable the delayed reset assertion when system is resumed.

ERR_PTR was dereferenced during sub domain parsing, if parent domain could not be obtained (because of invalid phandle or deferred registration of parent domain). The Exynos power domain code checked whether of_genpd_get_from_provider() returned NULL and in that case it skipped that power domain node. However this function returns ERR_PTR or valid pointer, not NULL.

Use `boot_cpu_data' to obtain the data from, following the approach that `cpu_has_*' macros take and avoiding the call to `smp_processor_id' made in the reference to `current_cpu_data'.

2015-05-12parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards ↵Helge Deller2-0/+7
architectures On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y, currently parisc and metag only) stack randomization sometimes leads to crashes when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB by default if not defined in arch-specific headers). The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the additional space needed for the stack randomization (as defined by the value of STACK_RND_MASK) was not taken into account yet and as such, when the stack randomization code added a random offset to the stack start, the stack effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK) which then sometimes leads to out-of-stack situations and crashes. This patch fixes it by adding the maximum possible amount of memory (based on STACK_RND_MASK) which theoretically could be added by the stack randomization code to the initial stack size. That way, the user-defined stack size is always guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK). This bug is currently not visible on the metag architecture, because on metag STACK_RND_MASK is defined to 0 which effectively disables stack randomization. The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP" section, so it does not affect other platformws beside those where the stack grows upwards (parisc and metag).

2015-05-12MIPS: fix FP mode selection in lieu of .MIPS.abiflags dataPaul Burton1-15/+17
Commit 46490b572544 ("MIPS: kernel: elf: Improve the overall ABI and FPU mode checks") reworked the ELF FP ABI mode selection logic, but when CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries which have no PT_MIPS_ABIFLAGS program header & associated .MIPS.abiflags section. A default mode is selected based upon whether the ELF contains MIPS32 or MIPS64 code, but that selection is made in arch_elf_pt_proc. arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is found. If one is not found then arch_elf_pt_proc is never called, and no default overall_fp_mode value is selected. When arch_check_elf is called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both prog_req & interp_req being set to none_req. none_req matches none of the conditions for mode selection at the end of arch_check_elf, so overall_fp_mode is left untouched. Finally once mips_set_personality_fp is called the BUG() in the default case is then hit & the kernel likely panics. Fix this by moving the selection of a default overall mode to the start of arch_check_elf, which runs once per ELF executed regardless of whether it has a PT_MIPS_ABIFLAGS program header.

Commit d795ef9aa831 ("arm64: perf: don't warn about missing interrupt-affinity property for PPIs") added a check for PPIs so that we avoid parsing the interrupt-affinity property for these naturally affine interrupts. Unfortunately, this check can trigger an early (successful) return and we will leak the irqs array. This patch fixes the issue by reordering the code so that the check is performed before any independent allocation.

2015-05-12ARM: vexpress/tc2: Add interrupt-affinity to the PMU nodeSudeep Holla1-0/+1
Commit 9fd85eb502a7 ("ARM: pmu: add support for interrupt-affinity property") added an optional "interrupt-affinity" property, to specify the CPU affinity for each SPI listed in the interrupts property. Without this property, we get this boot warning: CPU PMU: Failed to parse <no-node>/interrupt-affinity[0] This patch adds interrupt-affinity to the PMU node in the vexpress-ca15_a7(a.k.a TC2) device tree.

Commit d9d1f3e2d711 ("ARM: l2c: check that DT files specify the required "cache-unified" property") mandates to specify this required property. Without this property, we get this boot warning: "L2C: device tree omits to specify unified cache" This patch adds "cache-unified" property to L2 cache node in vexpress CA9 device tree.
