The find_pattern() debug output was printing the 'skip' character. This can be a NULL-byte and messes up further pr_debug() output. Output without the fix: kernel: nf_conntrack_ftp: Pattern matches! kernel: nf_conntrack_ftp: Skipped up to `<7>nf_conntrack_ftp: find_pattern `PORT': dlen = 8 kernel: nf_conntrack_ftp: find_pattern `EPRT': dlen = 8 Output with the fix: kernel: nf_conntrack_ftp: Pattern matches! kernel: nf_conntrack_ftp: Skipped up to 0x0 delimiter! kernel: nf_conntrack_ftp: Match succeeded! kernel: nf_conntrack_ftp: conntrack_ftp: match `172,17,0,100,200,207' (20 bytes at 4150681645) kernel: nf_conntrack_ftp: find_pattern `PORT': dlen = 8 Signed-off-by: Thomas Jarosch <thomas.jarosch@intra2net.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
