2025-05-02newlib: riscv: Remove unnecessary byte load for strlen()Eric Salem1-7/+7
For architectures where XLEN is 32 bits, when detecting a null byte, a word is read at a time. Once a null is found in the word, its precise location is then determined. Make clear to the compiler that if the first three bytes are not null, the last byte must be null, and does not need to be read from the string, since its value is always zero.

2025-05-02Cygwin: cygwin_conv_path: don't write to `to` before size is validated.Jeremy Drake via Cygwin-patches2-1/+7
In the CCP_POSIX_TO_WIN_W path, when `from` is a device, cygwin_conv_path would attempt to write to the `to` buffer before the validation of the `size`. This resulted in an EFAULT error in the common use-case of passing `to` as NULL and `size` as 0 to get the required size of `to` for the conversion (as used in cygwin_create_path). Instead, set a boolean and write to `to` after validation. Fixes: 43f65cdd7dae ("* Makefile.in (DLL_OFILES): Add fhandler_procsys.o.")

2025-05-02Cygwin: signal: Do not handle signals while waiting for wakeup evtTakashi Yano2-12/+11
... Otherwise, the opportunity for cleanup the wakeup event handle etc. may be lost because the user signal handler never returns if it calls longjmp(). This results in handle leak because the wakeup event handle will not be closed. This issue happens when the commnad e.g. "stress-ng --mprotect 1 -t 5" is executed. Instead, call call_signal_handler() after cleaning up if some signals are armed during waiting wakeup event. This essentially reverts the commit d243e51ef1d3, however, the deadlock fixed by that commit no longer occurs even reverting it for some reason. This is probably due to the redesign of the signal queue. In addition, do not touch "incyg" flag in _cygtls::call_signal_handler() because the process is still in the cygwin function when a user signal handler is called from the cygwin functions such as cygwait().

Also, use a tmp_pathbuf for the GetModuleFileNameW buffer, so that any buffer size limitation will definitely be due to the size of dli_fname, and add a static_assert of the size of dli_fname so we can be sure we're using the right size constant here.

Change register t1 to register a4, so that the affected instructions can be compressed. Since now we have less registers available, the following changes need to be made: In the previous version of this function, a4 was used to hold the offset that needs to be added to source and destination addresses before copying any data in the case of source address > destination address. Since a4 now holds the destination address, this offset is not calculated anymore. Instead, the value in a2 (the number of bytes to be copied) is added to the source and destination addresses. Therefore, in the case of source address > destination adress, a value of 1 needs to be subtracted from both addresses before starting the copying process.

Before this commit, these functions were always invoked in bg_check(), regardless of whether the current mode was already tty::cygwin.

2025-04-06Cygwin: fork: Call pthread::atforkchild () after other initializationsTakashi Yano2-1/+6
Previously, the callback registered by pthread_atfork() was called in pthread::atforkchild() before _my_tls.fixup_after_fork(). This caused misbehaviour if the callback used TLS-related functions. More specifically, cygwait() for a mutex at the beginning of fhandler_fifo_pipe::raw_write() failed because the event handle _my_tls.signal_arrived, which is used in cygwait() internally and designed to be initialized in _cygtls::fixup_after_fork(), was not yet initialized at that point. Due to this problem, subprocesses of CMake (versions >= 3.29.x) sometimes failed after the commit 7ed9adb356df ("Cygwin: pipe: Switch pipe mode to blocking mode by default, 2024-09-05"). This commit triggered the issue because it introduced cygwait() for the mutex in fhandler_fifo_pipe::raw_write(). This patch moves the pthread::atforkchild() at the end of the fork:: child(), i.e. after all initializations for child process is finished. The reason why the issue happens not always but sometimes: The event handle signal_arrived was never properly initialized when fhandler_fifo_pipe::raw_write() was called from the callback. As a result, its value was merely copied from the parent process during a fork() operation. Since the event signal_arrived was not created as inheritable, the handle value was fundamentally invalid. Despite this, the issue only occurred occasionally. This inconsistency was due to the handle value often coinciding with other existing handles because of its small value, such as 0x1ac. As evidence of this, in many cases where the issue did not manifest, the signal_arrived handle was not even an event handle.

2025-04-03Cygwin: testsuite: More fixes for compatibility with GCC 15Thirumalai Nagalingam2-100/+74
GCC 15 defaults to `-std=gnu23`, causing build failures in `testsuite` due to outdated C function declarations. This patch updates the function declarations to align with modern standards.
2025-04-02Cygwin: handle GetProcAddress returning NULL in GetArm64ProcAddress.Jeremy Drake1-2/+2
This was an oversight, the caller of GetArm64ProcAddress does check for a NULL return, but it would have crashed in the memcmp before getting there. Fixes: 2c5f25035d9f ("Cygwin: add find_fast_cwd_pointer_aarch64.") Signed-off-by: Jeremy Drake <cygwin@jdrake.com>
2025-04-02newlib: riscv: Fix build and reorganize header filesEric Salem6-11/+21
The sys/asm.h header file is included for certain assembly files, so move the typedef to a separate header file due to the build breaking on some systems. Also include the port's string header file (and move and rename) instead of the system's version. Addresses: https://sourceware.org/pipermail/newlib/2025/021591.html Fixes: c3b9bb173c8c ("newlib: riscv: Add XLEN typedef and clean up types") Reported-by: Jeff Law <jlaw@ventanamicro.com> Suggested-by: Kito Cheng <kito.cheng@gmail.com> Signed-off-by: Eric Salem <ericsalem@gmail.com>
2025-04-01RISC-V: Fix the asm code for large code modelKito Cheng2-1/+47
The large code model assume the data may far away from the code, so we must put the address of the target data wihin the `.text` section, normally we will just put within the function or nearby the function to prevent it out-of-range. Report from riscv-gnu-toolchain: https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1699 Verified with riscv-gnu-toolchain with rv64gc.
2025-03-31Cygwin: add find_fast_cwd_pointer_aarch64.Jeremy Drake3-6/+229
This works for aarch64 hosts when the target is aarch64, x86_64, or i686, with only a small #if block in one function that needs to care. Signed-off-by: Jeremy Drake <cygwin@jdrake.com>
