| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys_accept4() was added in kernel 2.6.28, but ARM was not updated to include it. The number and types of parameters is such that no ARM-specific processing is needed, so wiring up sys_accept4() just requires defining __NR_accept4 and adding a direct call in the syscall entry table. Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original accept4() test program, modified to define __NR_accept4 for ARM. Using the updated unistd.h also eliminates a warning then building glibc (2.10.2 and newer) about accept4() being unimplemented.

* / Make do_execve() take a const filename pointerDavid Howells2010-08-17
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Make do_execve() take a const filename pointer so that kernel_execve() compiles correctly on ARM: arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type This also requires the argv and envp arguments to be consted twice, once for the pointer array and once for the strings the array points to. This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.

| * | | | ARM: stack protector: change the canary value per taskNicolas Pitre2010-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new random value for the canary is stored in the task struct whenever a new task is forked. This is meant to allow for different canary values per task. On ARM, GCC expects the canary value to be found in a global variable called __stack_chk_guard. So this variable has to be updated with the value stored in the task struct whenever a task switch occurs. Because the variable GCC expects is global, this cannot work on SMP unfortunately. So, on SMP, the same initial canary value is kept throughout, making this feature a bit less effective although it is still useful. One way to overcome this GCC limitation would be to locate the __stack_chk_guard variable into a memory page of its own for each CPU, and then use TLB locking to have each CPU see its own page at the same virtual address for each of them.

Such actions are stopping the secondary CPUs. So, change the ARM implementation of these to reflect what x86 does.

C3. Therefore, we need to adapt things such that the TWD code can cope with this. We do this by always providing a broadcast tick function, and marking the fact that the TWD local timer will stop in low power modes. This means that when the CPU is placed into a low power mode, the core timer code marks this fact, and allows an IPI to be given to the core.

Rather than have every processors proc_fin() implementation do this, move it out into generic code - and move the cache flush past setup_mm_for_reboot() (so it can benefit from having caches still enabled.) This allows cpu_proc_fin() to become independent of the L1/L2 cache types, and eventually move the L2 cache flushing into the L2 support code.

This change is needed to make TCM detection more dynamic while still being able to compile code into it, and is a must for the unified ARM goals: the current TCM allocation at different places in memory for each machine would be a nightmare if you want to compile a single image for more than one machine with TCM so it has to be nailed down in one place.

| | * | ARM: 6207/1: Replace CONFIG_HAS_TLS_REG with HWCAP_TLS and check for it on V6Tony Lindgren2010-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TLS register is only available on ARM1136 r1p0 and later. Set HWCAP_TLS flags if hardware TLS is available and test for it if CONFIG_CPU_32v6K is not set for V6. Note that we set the TLS instruction in __kuser_get_tls dynamically as suggested by Jamie Lokier <jamie@shareable.org>. Also the __switch_to code is optimized out in most cases as suggested by Nicolas Pitre <nico@fluxnic.net>.
