I'd like to apply this generated patch but the patch command is asking me for a file path name :

administrator@server:~$ diff -Nau /etc/php/8.1/fpm/pool.d/www.conf /etc/php/8.1/fpm/pool.d/www.NEW.conf > ~/php8.1-fpm-www.conf.patch administrator@server:~$ sudo patch -p0 < ~/php8.1-fpm-www.conf.patch Ignoring potentially dangerous file name /etc/php/8.1/fpm/pool.d/www.conf Ignoring potentially dangerous file name /etc/php/8.1/fpm/pool.d/www.NEW.conf cant find file to patch at input line 3 Perhaps you used the wrong -p or --strip option? The text leading up to this was: -------------------------- |--- /etc/php/8.1/fpm/pool.d/www.conf 2022-09-15 13:30:49.000000000 +0200 |+++ /etc/php/8.1/fpm/pool.d/www.NEW.conf 2022-11-07 16:40:35.555078608 +0100 -------------------------- File to patch: ^C administrator@server:~$

You need to strip the first component, /, and start from the root directory:

cd / sudo patch -p1 < ~/php8.1-fpm-www.conf.patch

GNU patch considers patch contents with file names outside the tree starting in the current directory (or the directory given by -d) to be unsafe (see CVE-2010-4651). It’s best to use relative paths, and I recommend minimising the path as far as makes sense since it allows the patch to be used in different contexts — in your case, I would in fact skip the directories entirely:

( cd /etc/php/8.1/fpm/pool.d && diff -u www.conf www.NEW.conf ) > ~/php8.1-fpm-www.conf.patch
