Suppressing these individually would add too much clutter.

code and emits an error message to help avoid unintentionally loading wrong elf.
2022-09-01Substantially increase context_t stack sizeAndrew Waterman1-1/+1
It's nearly free to do so, because it's just virtual address space. @davidbiancolin recently fell into this pit when using context_t with VCS.
2022-07-17remove unnecessary ifdef for RISCV_ENABLE_DUAL_ENDIANWeiwei Li1-8/+0
the default target endian is always little endian: - mmu::is_target_big_endian() return false - sim_t::get_target_endianness() return memif_endianness_little when RISCV_ENABLE_DUAL_ENDIAN macro is undefined

We don't actually need encoding.h, so don't include it.

...which includes program loading.
2022-03-17Don't respond to invalid HTIF operations with assertion failuresAndrew Waterman1-1/+0
They should cause bad behavior in target land rather than crashing the simulator.

2021-08-26fesvr: replace use of `std::vector::operator[0]`Saleem Abdulrasool4-41/+41
This replaces multiple uses of `std::vector::operator[]` where the parameter is a constant `0` with the use of C++11's `std::vector::data` method. This fixes the root cause of invalid memory accesses. `std::vector::operator[]` is an unchecked memory access, and when the buffers are zero-sized (that is the buffer container is empty) either due to a 0 padding in the case of elfloader or NULL parameters to syscalls where permitted, the unchecked access may cause an invalid memory access. The use of `std::vector::data` is permitted even in such a case, though the returned memory may not be dereferenced. The general usage of the returned pointer is to pass to `memif_t`, which is careful about 0-sized buffer accesses, and so passing the result of `std::vector::data` is safe. This is theoretically a better access pattern as it also avoids having the compiler to re-materialize the pointer from the de-referenced location.
2021-08-26fesvr: avoid an invalid memory accessSaleem Abdulrasool1-3/+5
`std::vector::operator[]` does not perform a bounds check when accessing the underlying memory. If the length of the padding is 0, this would access an invalid memory location. Guard against this by ensuring that we have any padding to apply by constant hoisting the length computation and checking the value.
2021-08-26fesvr: format `LOAD_ELF` macro (NFC)Saleem Abdulrasool1-43/+50
This simply uses clang-format to reflow the text of the macro, which makes it easier to read and edit.
2021-07-28Significantly speed up compilation with GCCAndrew Waterman1-2/+0
Precompiled headers were broken because they weren't compiled with the same -fPIC setting as the rest of the code. Fix by just making everything use -fPIC.

2020-10-21Update htif.cc (#577)S.Pawan Kumar1-1/+1
Bug fix for final byte in signature output.
2020-10-15reduce sig_len constraint to 4 bytes (#569)Neel Gala2-6/+20
* reduce sig_len constraint to 4 bytes Spike currently asserts that the signature length should always be a multiple of 16-bytes. However, the compliance suite has agreed to upon the signature being a multiple ot 4-bytes. This prevents some of the tests to run on spike since it fails the assertion. The proposed change fixes this issue and reduces the assertion to 4 bytes. * Added size argument to htif arguments and zero padding for signature output. Defaultline size-16. * Modified type of line_size to unsigned. * Renamed size to granularity. * Rename granularity to signature-granularity. Co-authored-by: dracarys99 <spawan1999@gmail.com>

2020-01-25Refuse to load non-EXEC/non-RISC-V/non-V1 ELFs (#388)Alexander Lent2-0/+10
Stricter validation of ELF binaries improves usability with informative assertions. This prevents users from loading ELF relocatable files and binaries compiled for their (non-RISC-V) workstations, for example. Without this patch, spike would attempt to load nearly any ELF given, but it would usually fail with an error about debug module accesses, since the given ELF causes accesses in the debug module's memory space. Even if spike successfully loaded the ELF file, it would still misbehave during simulation, for example in the case of ELF relocatable files. ELF magic numbers come from official ELF documents: TIS ELF spec v1.2, via Linux Foundation Referenced Specifications See: https://refspecs.linuxbase.org/ RISC-V magic number comes from official RISC-V ELF documents: See: riscv/riscv-elf-psabi-doc@60c25981b62c0b43d16142f8a12c8b1e98e60d4d
