2024-06-16Cygwin: suppress a warning generated with w32api >= 12.0.0Jon Turney1-0/+3
w32api 12.0.0 adds the returns_twice attribute to RtlCaptureContext(). There's some data-flow interaction with using it inside a while loop which causes a maybe-uninitialized warning. ../../../../winsup/cygwin/exceptions.cc: In member function 'int _cygtls::call_signal_handler()': ../../../../winsup/cygwin/exceptions.cc:1720:33: error: '<anonymous>' may be used uninitialized in this function [-Werror=maybe-uninitialized]

2024-06-02Cygwin: pthread: Fix a race issue introduced by the commit 2c5433e5da82Takashi Yano3-17/+25
To avoid race issues, pthread::once() uses pthread_mutex. This caused the handle leak which was fixed by the commit 2c5433e5da82. However, this fix introduced another race issue, i.e., the mutex may be used after it is destroyed. This patch fixes the issue. Special thanks to Bruno Haible for discussing how to fix this.

2024-05-22arc: libc, libgloss: Remove .file directive from .S filesYuriy Kolerov2-5/+2
Assembler for ARCv2 always extends the name provided by .file directive to an absolute form. On ARCv3 targets .file directive forces assembler to put a provided string to DW_AT_name field as is without extending to an absolute path. Then GDB cannot find source files because of it. The best way to fix this issue is just delete lines with .file directive in .S files and let the compiler to decide what DW_AT_name must contain. Particularly, the compiler fills this filed by an absolute path to a .S file because only absolute paths are used in toolchain's build process. Signed-off-by: Yuriy Kolerov <kolerov93@gmail.com>

2024-05-22arc: libgloss: Use long calls attribute for exit_haltClaudiu Zissulescu1-2/+2
According to GCC documentation for ARC, a function marked with the long_call attribute is always called using register-indirect jump-and-link instructions, thereby enabling the called function to be placed anywhere within the 32-bit address space. exit_halt function is provided by crt0.S and it's used in nsim-syscalls.c.

2024-04-09Cygwin: globify: read full 32 bit characterCorinna Vinschen2-1/+6
While commit 0321fb573654 ("Cygwin: glob: convert wchar_t to wint_t") switched the entire glob mechanism from wchar_t to wint_t, the globify function calling glob on a DOS command line did not catch up and only checked for the next character constituting a 16 bit wchar_t. This broke reading surrogate pairs from incoming DOS command lines if the string had to go through glob(3). Check for an entire 32 bit unicode char instead.

Commit a0a25849f9dd ("Cygwin: fhandler_virtual: move fileid to path_conv member") broke `ls -l /proc/<PID>'. Turns out, the commit forgot to set the fileid in case of a virtual root dir (i. e., returning virt_rootdir) in fhandlers utilizing fileid. This crashed opendir() due to a random fileid.

2024-04-02Cygwin: fhandler_virtual: move fileid to path_conv memberCorinna Vinschen8-24/+36
Commit 80f722e97cf7 ("Cygwin: opendir(3): move ENOTDIR check into main function") introduced a bug in fhandler_virtual handling. While the assertion that path_conv::check() already calls exists() and sets FILE_ATTRIBUTE_DIRECTORY accordingly, the exists() function is called on a fhandler_virtual object created for just this code snippet. The side effect of this is that the fileid member in the calling fhandler_virtual object is not set after path_conv::check(). Move the fhandler_virtual::fileid member to path_conv::_virt_fileid and create matching path_conv::virt_fileid() and fhandler_virtual::fileid() methods. Let path_conv::check() propagate the fileid set in the local fhandler_virtual::exists() call to its own _virt_fileid. Use new fhandler_virtual::fileid() method throughout.

Checking server existence by trying to enumerate its shares may result in 2 minutes delay until some internal timeout is hit. In the light that every network is an IP network anyway these days, let's try with a simple getaddrinfo() call. This is usually back in 3 secs even if the server doesn't exist, and it's usually back in 8 secs if the DNS server can't be connected. This is the fastest method I found to check server existence yet. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
