| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The KSTK_EIP() and KSTK_ESP() macros should return the user program counter (PC) and stack pointer (A0StP) of the given task. These are used to determine which VMA corresponds to the user stack in /proc/<pid>/maps, and for the user PC & A0StP in /proc/<pid>/stat. However for Meta the PC & A0StP from the task's kernel context are used, resulting in broken output. For example in following /proc/<pid>/maps output, the 3afff000-3b021000 VMA should be described as the stack: # cat /proc/self/maps ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 And in the following /proc/<pid>/stat output, the PC is in kernel code (1074234964 = 0x40078654) and the A0StP is in the kernel heap (1335981392 = 0x4fa17550): # cat /proc/self/stat 51 (cat) R ... 1335981392 1074234964 ... Fix the definitions of KSTK_EIP() and KSTK_ESP() to use task_pt_regs(tsk)->ctx rather than (tsk)->thread.kernel_context. This gets the registers from the user context stored after the thread info at the base of the kernel stack, which is from the last entry into the kernel from userland, regardless of where in the kernel the task may have been interrupted, which results in the following more correct /proc/<pid>/maps output: # cat /proc/self/maps ... 0800b000-08070000 r-xp 00000000 00:02 207 /lib/libuClibc-0.9.34-git.so ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 [stack] And /proc/<pid>/stat now correctly reports the PC in libuClibc (134320308 = 0x80190b4) and the A0StP in the [stack] region (989864576 = 0x3b002280): # cat /proc/self/stat 51 (cat) R ... 989864576 134320308 ...

The change modified cpu_init() in common.c, so that the shadow CR4 gets initialized before anything uses it. Unfortunately, there's two cpu_init()s in common.c. There's one for 64-bit and one for 32-bit. The commit only added the shadow init to the 64-bit path, but the 32-bit path needs the init too.

It analyzes all the instructions from the beginning of the function until the given address. The code might be modified by another Kprobe. In this case, the current code is read into a buffer, int3 breakpoint is replaced by the saved opcode in the buffer, and can_probe() analyzes the buffer instead. There is a bug that __recover_probed_insn() tries to restore the original code even for Kprobes using the ftrace framework. But in this case, the opcode is not stored. See the difference between arch_prepare_kprobe() and arch_prepare_kprobe_ftrace(). The opcode is stored by arch_copy_kprobe() only from arch_prepare_kprobe(). This patch makes Kprobe to use the ideal 5-byte NOP when the code can be modified by ftrace. It is the original instruction, see ftrace_make_nop() and ftrace_nop_replace(). Note that we always need to use the NOP for ftrace locations. Kprobes do not block ftrace and the instruction might get modified at anytime. It might even be in an inconsistent state because it is modified step by step using the int3 breakpoint. The patch also fixes indentation of the touched comment. Note that I found this problem when playing with Kprobes. I did it on x86_64 with gcc-4.8.3 that supported -mfentry. I modified samples/kprobes/kprobe_example.c and added offset 5 to put the probe right after the fentry area: static struct kprobe kp = { .symbol_name = "do_fork", + .offset = 5, }; Then I was able to load kprobe_example before jprobe_example but not the other way around: $> modprobe jprobe_example $> modprobe kprobe_example modprobe: ERROR: could not insert 'kprobe_example': Invalid or incomplete multibyte or wide character It did not make much sense and debugging pointed to the bug described above.

Usually, these defines are provided by <asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>. But some architectures fold page table levels in a custom way. They need to define these macros themself. This patch adds missing defines. The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc() and __pud_alloc() on architectures without these page table levels. Signed-off-by: Kirill A.

As a temporary fix we remove the extcon handle from the USB controller and add it back when the extcon driver merges in v4.1.

As only three address lines are connected both 0 and 0x300 will work just fine with 0 being correct. The warning about the non-standard offset can be fixed by writing to EEPROM as that's needed in any case to set the MAC address.

After testing the USB with actual devices I noticed a few issues that should be fixed to avoid confusion: - The USB id pin on dm8168-evm is hardwired and can be changed only by software. As there are two USB-A type connectors, let's start both in host mode instead of otg. - The Mentor core is configured in such a way on dm8168-evm that it's not capable of multipoint at least on revision c board that I have. - We need ranges for the syscon to properly set up the phy as children of the SCM syscon area. - Let's not disable the second interface, the board specific dts files can do that if really needed. Most boards should just keep it enabled to ensure the device is idled properly. Note that also a phy and several musb fixes are still needed to make the USB to work properly in addition to this fix.

The current ARM64 CPUidle driver does not include asm/proc-fns.h explicitly and it has so far relied on implicit inclusion from other header files. Owing to some header dependencies reshuffling this currently triggers build failures when CONFIG_ARM64_64K_PAGES=y: drivers/cpuidle/cpuidle-arm64.c: In function "arm64_enter_idle_state" drivers/cpuidle/cpuidle-arm64.c:42:3: error: implicit declaration of function "cpu_do_idle" [-Werror=implicit-function-declaration] cpu_do_idle(); ^ This patch adds the explicit inclusion of the asm/proc-fns.h header file in the arm64 asm/cpuidle.h header file, so that the build breakage is fixed and the required header inclusion is added to the appropriate arch back-end CPUidle header, already included by the CPUidle arm64 driver, where CPUidle arch related function declarations belong.

| * | | | arm64: compat Fix siginfo_t -> compat_siginfo_t conversion on big endianCatalin Marinas2015-02-271-3/+2

When a compat application invokes a syscall that takes a sigval_t value (as part of a larger structure, e.g. compat_sys_mq_notify, compat_sys_timer_create), the compat_sigval_t union is converted to the native sigval_t with sival_int overlapping with either the least or the most significant half of sival_ptr, depending on endianness. When the corresponding signal is delivered to a compat application, on big endian the current (compat_uptr_t)sival_ptr cast always returns 0 since sival_int corresponds to the top part of sival_ptr. This patch fixes copy_siginfo_to_user32() so that sival_int is copied to the compat_siginfo_t structure.

| * | | | arm64: crypto: increase AES interleave to 4xArd Biesheuvel2015-02-261-1/+1

This improves performance on Cortex-A57 by ~35%. This is due to the 3-cycle latency of AES instructions on the A57's relatively deep pipeline (compared to Cortex-A53 where the AES instruction latency is only 2 cycles). At the same time, disable inline expansion of the core AES functions, as the performance benefit of this feature is negligible.

| * | | | arm64: enable PTE type bit in the mask for pte_modifyFeng Kan2015-02-261-1/+1

The pte_modify does not allow modification for PTE type bit. This cause the test to hang the system. It is found that the PTE can't transit from an inaccessible page (b00) to a valid page (b11) because the mask does not allow it. This happens when a big block of mmaped memory is set the PROT_NONE, then the a small piece is broken off and set to PROT_WRITE | PROT_READ cause a huge page split.

This behavior is incorrect. It should fall back to syscall when an unrecognized clock id is passed, even when the timespec argument is null. This ensures that clock_getres always returns an error for invalid clock ids.
