2024-06-28Cygwin: dsp: Fix incorrect openflags when opening multiple /dev/dspTakashi Yano2-13/+20
Previously, the following steps failed with error: 1) Open /dev/dsp with O_RDONLY 2) Open /dev/dsp with O_WRONLY 3) Issue SNDCTL_DSP_GETOSPACE ioctl() for 2) This is because IS_WRITE() returns false for 2) due to incorrect openflags handling in archetype instance. This patch fixes the issue by adding open_setup() to fhandler_dev_dsp to set openflags correctly for each instance.

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.

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>

So far the check for a directory is in the fhandler::opendir methods.

If pipe reader is a non-cygwin app first, and cygwin process reads the same pipe after that, the pipe has been set to bclocking mode for the cygwin app. However, the commit 9e4d308cd592 assumes the pipe for cygwin process always is non-blocking mode.

Chances are high that Cygwin recalls offline files from remote storage, even if the file is only accessed during stat(2) or readdir(3). To avoid this - make sure Cygwin is placeholder-aware, - open files in path_conv handling, as well as in stat(2)/readdir(3) scenarios with FILE_OPEN_NO_RECALL, and - during symlink checking or testing for executablility, don't even try to open the file if one of the OFFLINE attributes is set.
