2032	fix kernel assertion (panic) on arm32 (BeagleBone and others... fix kernel assertion (panic) on arm32 (BeagleBone and others) in frame_reference_add() The macro PTE_GET_FRAME_ARCH() retrieves a physical frame number from the page table entry. Although the frame_base_addr member of the page table entry structure (pte_t) is declared as an unsigned bit field, due to the integer promotion rules the value is interpreted as a signed integer. C99-§6.3.1.1: Boolean, characters, and integers 2: If an int can represent all values of the original type (as restricted by the width, for a bit-field), the value is converted to an int; otherwise, it is converted to an unsigned int. These are called the integer promotions. All other types are unchanged by the integer promotions. Since the bitwise shift operations in PTE_GET_FRAME_ARCH() and especially in ADDR2PFN() (used by anon_share() in backend_anon.c) are applied on a signed integer, they create a false sign-extended (negative) physical frame number that is then passed to frame_reference_add(). This routine is obviously unable to find a valid physical memory zone for the malformed frame number and hits the assertion. The fix is to explicitly typecast the value in PTE_GET_FRAME_ARCH() as unsigned. The original panic and stack trace for reference: ######> Kernel panic on cpu0 due to a failed assertion: <###### frame_reference_add() at generic/src/mm/frame.c:976: znum != (size_t) -1 THE=0x802ca000: pe=1 thr=0x802c8000 task=0x802c1000 cpu=0x80292800 as=0x8000112c magic=0xfacefeed 0x802cbd2c: generic/src/debug/stacktrace.o:stack_trace()+0x0000001c 0x802cbd5c: generic/src/debug/panic.o:panic_common()+0x000001b4 0x802cbd94: generic/src/mm/frame.o:frame_reference_add()+0x000000a8 0x802cbdf4: generic/src/mm/backend_anon.o:anon_share()+0x00000168 0x802cbe44: generic/src/mm/as.o:as_area_share()+0x000001bc 0x802cbe7c: generic/src/ipc/ops/sharein.o:answer_preprocess()+0x0000007c 0x802cbeb4: generic/src/ipc/sysipc.o:answer_preprocess()+0x000000a4 0x802cbf04: generic/src/ipc/sysipc.o:sys_ipc_answer_fast()+0x0000007c 0x802cbf4c: generic/src/syscall/syscall.o:syscall_handler()+0x000000e0 0x802cbf74: arch/arm32/src/exception.o:swi_exception()+0x00000034 0x802cbfb4: generic/src/interrupt/interrupt.o:exc_dispatch()+0x00000144 cpu0: halted	Martin Decky	10 years ago
2031	Merge GCC port updates Merge GCC port updates libposix changes * unimplemented methods do not abort, they warn instead * add pthread.h, no implementation yet * speed-up symbol redefinition (objcopy can work with static libraries as well) * add some functions already implemented in libc to libposix toolchain changes * experimental support for HelenOS-specific toolchain * toolchain.sh --helenos-target * adds -helenos- target, e.g. we can have amd64-helenos-gcc * added as another choice to HelenOS.config, updated other scripts accordingly * added non-root compilation * install into PKG/ to be later copied to real root (package-like installation)	Vojtech Horky	10 years ago

2021	Address compare functions should return non-zero on match - ... Address compare functions should return non-zero on match - logic is inverted. addr128_t is big endian in host memory, so it should never be byte-swapped.	Jiri Svoboda	10 years ago
