[PATCH 5/6] forkables: Keep hardlinks disabled via shared mem.

To avoid the need for each process to check the filesystem to detect that hardlink creation is impossible or disabled, cache this fact in shared memory. Removing cygfork directory while in use does disable hardlinks creation. To (re-)enable hardlinks creation, the cygfork directory has to exist

[PATCH 3/6] forkables: Create forkable hardlinks, yet unused.

In preparation to protect fork() against dll- and exe-updates, create hardlinks to the main executable and each loaded dll in subdirectories of /var/run/cygfork/, if that one exists on the NTFS file system. The directory names consist of the user sid, the main executable's NTFS IndexNumber, and

[PATCH 1/6] forkables: Store dll file name as full NT path.

In preparation to protect fork() against dll- and exe-updates, store any dll file name as full NT path. Additionally, keep a file handle open for each loaded dll file for subsequent hardlink creation. The earlier we open a handle to the dll file, the lower is the chance the dll file has been

[PATCH 0/6] Protect fork() against dll- and exe-updates.

Hi, this is the updated and split series of patches to use hardlinks for creating the child process by fork(), in reply to https://cygwin.com/ml/cygwin-developers/2016-01/msg2.html https://cygwin.com/ml/cygwin-developers/2016-03/msg5.html http://thread.gmane.org/gmane.os.cygwin.devel/1378

[PATCH 4/6] forkables: Protect fork against dll-, exe-updates.

To support in-cygwin package managers, the fork() implementation must not rely on .exe and .dll files to stay in their original location, as the package manager's job is to replace these files. Instead, we use the hardlinks to the original binaries in /var/run/cygfork/ to create the child process

[PATCH 2/6] forkables: Track main executable and cygwin1.dll.

In preparation to protect fork() against dll- and exe-updates, even for the main executable and cygwin1.dll store the file name as full NT path, and keep handles to the files open for subsequent hardlink creation. Create the child process using the main executable's file name converted from the
