2023-09-17Cygwin: dsp: Avoid setting buffer that is too small.Takashi Yano1-0/+2
The buffer size that is too small causes choppy sound. That is not practical at all. With this patch, the minimum value of the buffer size (i.e. fragstotal * fragsize) is restricted to 16384 bytes. Signed-off-by: Takashi Yano <takashi.yano@nifty.ne.jp>
2023-09-17Cygwin: dsp: Fix a bug that app hangs if it killed during write().Takashi Yano1-1/+2
If app is killed during blocking write(), it sometimes hangs. This patch fixes the issue. Signed-off-by: Takashi Yano <takashi.yano@nifty.ne.jp>
2023-09-11Reentrancy, attempt to always provide _Thread_local in <sys/reent.h>Pekka Seppänen1-0/+1
Attempt to always provide _Thread_local in <sys/reent.h> by including <sys/cdefs.h>. The C specific keyword _Thread_local is not available unless targetting a suitable C version.
2023-09-11Reentrancy, conditionally provide default __getreent() implementationPekka Seppänen1-0/+4
Conditionally provide default __getreent() implementation only if _REENT_THREAD_LOCAL is not defined. If struct _reent is replaced by dedicated thread-local objects neither the structure nor _impure_ptr is available.
2023-09-11Reentrancy, use _REENT_ERRNO()Pekka Seppänen4-14/+14
Use _REENT_ERRNO() macro to access errno. This encapsulation is required, as errno might be either _errno member of struct _reent, _tls_errno or any such implementation detail.

2023-09-09Cygwin: NFS: remove recognizing native symlinks as FIFOsCorinna Vinschen1-15/+0
Given the downsides of NFS symlinks as FIFOs, drop the code added to recognize them as such. Fixes: 622fb0776ea3 ("Cygwin: enable usage of FIFOs on NFS") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-09-09Cygwin: NFS: create devices (especially FIFOs) as shortcut filesCorinna Vinschen2-4/+26
Creating real NFS symlinks for device files has a major downside: The way we store device info requires to change the symlink target in case of calling chmod(2). This falls flat in two ways: - It requires to remove and recreate the symlink, so it doesn't exist for a short period of time, and - removing fails badly if there's another open handle to the symlink. Therefore, change this to create FIFOs as shortcut files, just as on most other filesystems. Make sure to recognize these new shortcuts on NFS (for devices only) in path handling and readdir.

2023-09-09Cygwin: NFS: fetch actual DOS attributesCorinna Vinschen2-3/+9
MSFT NFSv3 fakes DOS attributes based on file type and permissions. Rather than just faking FILE_ATTRIBUTE_DIRECTORY for dirs, fetch the "real" DOS attributes returned by NFS. This allows to handle the "R/O" attribute on shortcut files and thus reading and creating device shortcut files on NFS. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2023-09-08Cygwin: fix chmod on native NFS FIFOsCorinna Vinschen2-3/+12

2023-09-04Cygwin: enable usage of FIFOs on NFSCorinna Vinschen2-12/+48
FIFOs on NFS were never recogized as such in path handling. stat(2) indicated native FIFOs as FIFOs but the path handling code didn't set the matching values in the inner symlink checking code, so the followup behaviour was wrong. Basically for the same reason, Cygwin-created FIFOs were just treated as symlinks with weird content by stat(2) as well as path handling. Add code to enable both types of FIFOs on NFS as Cygwin FIFOs. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2023-09-01Cygwin: sys/cpuset.h: add cpuset-specific external functionsCorinna Vinschen3-14/+25
The latest incarnation of sys/cpuset.h broke building coreutils. The reason is the inclusion of stdlib.h and string.h and hence premature requests for datatypes not yet defined in the include chain. Avoid this by defining __cpuset_alloc and __cpuset_free as external functions, now defined in sched.cc. Linux is doing this too, just using different names for the functions. Redefine __cpuset_zero_s to use __builtin_memset only on compilers supporting it, otherwise using a simple loop. Drop the stdlib.h and string.h includes.

2023-08-29libc/stdlib/nano-mallocr.c, typo in variable namePekka Seppänen1-1/+1
Nano malloc uses `size' in assertation whereas the correct variable would be `s'. Given this has existed ever since nano malloc support was added, based on the context ("returned payload area of desired size does not exceed the actual allocated chunk") I presume that indeed `s' (user input) and not `r->size' (computed) shall be used.
2023-08-29Cygwin: execve: drop argument size limitCorinna Vinschen6-24/+38
Before commit 44f73c5a6206 ("Cygwin: Fix segfalt when too many command line args are specified.") we had no actual argument size limit, except for the fact that the child process created another copy of the argv array on the stack, which could result in a stack overflow and a subsequent SEGV. Commit 44f73c5a6206 changed that by allocating the additional argv array via malloc, and it introduced a new SC_ARG_MAX limit along the lines of the typical Linux limit. However, this new limit is artificial. Cygwin allocates all argument and environment data on the cygheap. We only run out of ARG_MAX space if we're out of memory resources. Change argument size handling accordingly: - Drop the args size check from child_info_spawn::worker. - Return -1 from sysconf (SC_ARG_MAX), i. e., the argument size limit is undefined. - Change argv handling in class av, so that a failing cmalloc is not fatal. This allows the parent process to return E2BIG if it's out of cygheap resources. - In the child, add a check around the new malloc call, so that it doesn't result in a SEGV if the child process gets unexpectedly into an ENOMEM situation at this point. In this (unlikely) case, proceed with the original __argv array instead. Add comment to explain why. Fixes: 44f73c5a6206 ("Cygwin: Fix segfalt when too many command line args are specified.")

2023-08-29Cygwin: Fix segfalt when too many command line args are specified.Takashi Yano5-7/+18
Previously, the number of command line args was not checked for cygwin process. Due to this, segmentation fault was caused if too many command line args are specified. https://cygwin.com/pipermail/cygwin/2023-August/254333.html Since char *argv[argc + 1] is placed on the stack in dll_crt0_1(), STATUS_STACK_OVERFLOW occurs if the stack does not have enough space. With this patch, char *argv[] is placed in heap instead of stack and ARG_MAX is increased from 32000 to 2097152 which is default value of Linux. The argument length is also compared with ARG_MAX and spawnve() returns E2BIG if it is too long.

2023-08-19Cygwin: pty: Fix failure to clear switch_to_nat_pipe flag.Takashi Yano3-4/+16
After the commit fbfea31dd9b9, switch_to_nat_pipe is not cleared properly when non-cygwin app is terminated in the case where the pseudo console is disabled. This is because get_winpid_to_hand_over() sometimes returns PID of cygwin process even though it should return only PID of non-cygwin process. This patch fixes the issue by adding a new argument which requests only PID of non-cygwin process to get_console_process_id().

After the commit 93508e5bb841, the access permissions argument passed to open_shared() is ignored and always replaced with (FILE_MAP_READ | FILE_MAP_WRITE). This causes the weird behaviour that sshd service process loses its cygwin PID. This triggers the failure in pty that transfer_input() does not work properly. This patch resumes the access permission settings to fix that.
