-print_string() displays characters as \\%.03o but without first

-to an int. This causes output like \37777777630 instead of \230.

-
-Once we've terminated the PPP session, there is no chance of a PPP layer
-disconnect. Some PPPoE relays don't detect the PPP session going down, and
-depend on a long timeout or a PPPoE PADT to terminate the session.
-
-Send a PADT on disconnect to work around these buggy relays.

-Subject: [PATCH] pppd: allow use of arbitrary interface names
-
-This is a modified version of a patch from openSUSE that enables PPP interfaces
-to be called arbitrary names, rather than simply pppX where X is the unit
-number.
-
-The modifications from the stock openSUSE patch are:
-  refresh patch on top of 018_ip up_option.diff
-- fix a printf format-string vulnerability in pppd/main.c:set_ifunit()
-- clarify the pppd.8 manpage additions
-- patch pppstats/pppstats.c to query renamed interfaces without complaint

-Subject: [PATCH] pppd: Provide error() implementation in pppoe-discovery
-
-The pppoe-discovery program calls error() from the CHECK_ROOM macro
-defined in pppoe.h. Since pppoe-discovery is a standalone program not
-linked with the rest of pppd, the only way this could build is by
-linking to glibc's proprietary error(3) function instead of the function
-of the same name (but with different arguments) defined in pppd/utils.c.
-
-So with glibc this builds, but will probably crash when the assertion is
-triggered. As the assertion is unlikely to fail, nobody has noticed.
-
-The build however fails with musl libc or uClibc since they don't
-provide the doppelganger.

-Subject: [PATCH] pppoe: include netinet/in.h before linux/in.h
-
-This fixes builds with newer kernels. Basically, <netinet/in.h> needs to be
-included before <linux/in.h> otherwise the earlier, unaware of the latter,
-tries to redefine symbols and structures. Also, <linux/if_pppox.h> doesn't work
-alone anymore, since it pulls the headers in the wrong order, so we better
-include <netinet/in.h> early.

-Subject: [PATCH] Bug#306261: pppd does not properly close /dev/ppp on persist
-
-When using the kernel PPPoE driver, pppd never
-closes /dev/ppp when the link has come down.
-
-It opens superfluous fds to the device each time it re-opens the
-connection, with the unclosed ones falsely reported always ready for
-data by select().
-
-This makes pppd eat up 100% CPU time after the first persist because of
-the always instantly returning select() on the unclosed fds.
-
-The problem also occurs with the upstream version, but does not occur
-when a pty/tty device is used for the ppp connection.

-Subject: [PATCH] Bug#284382: ppp: linkpidfile is not created upon detachment
-
-Package: ppp
-Version: 2.4.2+20040428-2
-Severity: wishlist
-
-When pppd detaches from the parent normally, that is, without nodetach
-or updetach set, the linkpidfile is not created even when linkname is
-set.

-This is because the create_linkpidfile call in detach() is only made
-if the linkpidfile is filled in.  However, linkpidfile is never filled
-in until create_linkpidfile has been called.
-
-IMHO the call should be made uncondtionally in detach() since
-create_linkpidfile does its own check on linkname anyway.
-
-Please note that the version of pppd in woody always wrote the
-linkpidfile after detaching.  It did so in main() however.  That
-call has now been removed which is why I'm seeing this problem.

-
-Add pppoe 'host-uniq' option to set an arbitrary
-host-uniq tag instead of the pppd pid.
-Some ISPs use such tag to authenticate the CPE,
-so it must be set to a proper value to connect.

-Subject: [PATCH] Add replacedefaultroute option
-
-Adds an option to pppd to control whether to replace existing default routes
-when using the 'defaultroute' option.
-
-If defaultroute and replacedefaultroute are both set, pppd replaces an existing
-default route with the new default route. The old default route is restored when
-the connection is taken down.
-
-Origin: vendor, https://build.opensuse.org/source/network/ppp/ppp-2.4.2-cifdefroute.diff?rev=7a0fdeff0b29437dd7f4581c95c7255a

-Subject: [PATCH] Fix buffer overflow in rc_mksid()
-
- rc_mksid converts the PID of pppd to hex to generate a pseudo-unique string.
- .
- If the process id is bigger than 65535 (FFFF), its hex representation will be
- longer than 4 characters, resulting in a buffer overflow.
- .
- The bug can be exploited to cause a remote DoS.

-+    security protocol that can be used with PPP.  It provides a means
-+    to plug in multiple optional authentication methods.
-+
-+    Transport Level Security (TLS; RFC 5216) provides for mutual
-+    authentication, integrity-protected ciphersuite negotiation and
-+    key exchange between two endpoints.  It also provides for optional
-+    MPPE encryption.
-+
-+    EAP-TLS (RFC 2716) incapsulates the TLS messages in EAP packets,
-+    allowing TLS mutual authentication to be used as a generic EAP
-+    mechanism. It also provides optional encryption using the MPPE
-+    protocol.
-+
-+    This patch provide EAP-TLS support to pppd.
-+    This authentication method can be used in both client or server
-+    mode.
-+
-+2. Building
-+
-+    To build pppd with EAP-TLS support, OpenSSL (http://www.openssl.org)
-+    is required. Any version from 0.9.7 should work.
-+
-+    Configure, compile, and install as usual.
-+
-+3. Configuration
-+
-+    On the client side there are two ways to configure EAP-TLS:
-+
-+    1. supply the appropriate 'ca', 'cert' and 'key' command-line parameters
-+
-+    2. edit the /etc/ppp/eaptls-client file.
-+    Insert a line for each system with which you use EAP-TLS.
-+    The line is composed of this fields separated by tab:
-+
-+      - Client name
-+        The name used by the client for authentication, can be *
-+      - Server name
-+        The name of the server, can be *
-+      - Client certificate file
-+        The file containing the certificate chain for the
-+        client in PEM format
-+      - Server certificate file
-+        If you want to specify the certificate that the
-+        server is allowed to use, put the certificate file name.
-+        Else put a dash '-'.
-+      - CA certificate file
-+        The file containing the trusted CA certificates in PEM
-+        format.
-+      - Client private key file
-+        The file containing the client private key in PEM format.
-+
-+
-+    On the server side edit the /etc/ppp/eaptls-server file.
-+    Insert a line for each system with which you use EAP-TLS.
-+    The line is composed of this fields separated by tab:
-+
-+      - Client name
-+        The name used by the client for authentication, can be *
-+      - Server name
-+        The name of the server, can be *
-+      - Client certificate file
-+        If you want to specify the certificate that the
-+        client is allowed to use, put the certificate file name.
-+        Else put a dash '-'.
-+      - Server certificate file
-+        The file containing the certificate chain for the
-+        server in PEM format
-+      - CA certificate file
-+        The file containing the trusted CA certificates in PEM format.
-+      - Client private key file
-+        The file containing the server private key in PEM format.
-+      - addresses
-+        A list of IP addresses the client is allowed to use.
-+
-+
-+    OpenSSL engine support is included starting with v0.95 of this patch.
-+    Currently the only engine tested is the 'pkcs11' engine (hardware token
-+    support). To use the 'pksc11' engine:
-+      - Use a special private key fileiname in the /etc/ppp/eaptls-client file:
-+          <engine>:<identifier>
-+        e.g.
-+          pkcs11:123456
-+
-+      - The certificate can also be loaded from the 'pkcs11' engine using
-+        a special client certificate filename in the /etc/ppp/eaptls-client file:
-+          <engine>:<identifier>
-+        e.g.
-+          pkcs11:123456
-+
-+      - Create an /etc/ppp/openssl.cnf file to load the right OpenSSL engine prior
-+        to starting 'pppd'. A sample openssl.cnf file is
-+
-+        openssl_conf = openssl_def
-+
-+        [ openssl_def ]
-+        engines = engine_section
-+
-+        [ engine_section ]
-+        pkcs11 = pkcs11_section
-+
-+        [ pkcs11_section ]
-+        engine_id = pkcs11
-+        dynamic_path = /usr/lib64/openssl/engines/engine_pkcs11.so
-+        MODULE_PATH = /usr/lib64/libeTPkcs11.so
-+        init = 0
-+
-+      - There are two ways to specify a password/PIN for the PKCS11 engine:
-+          - inside the openssl.cnf file using
-+              PIN = your-secret-pin
-+            Note The keyword 'PIN' is case sensitive!
-+          - Using the 'password' in the ppp options file.
-+        From v0.97 of the eap-tls patch the password can also be supplied
-+        using the appropriate 'eaptls_passwd_hook' (see plugins/passprompt.c
-+        for an example).
-+
-+
-+4. Options
-+
-+    These pppd options are available:
-+
-+      ca <ca-file>
-+        Use the CA public certificate found in <ca-file> in PEM format
-+      cert <cert-file>
-+        Use the client public certificate found in <cert-file> in PEM format
-+        or in engine:engine_id format
-+      key <key-file>
-+        Use the client private key found in <key-file> in PEM format
-+        or in engine:engine_id format
-+      crl <crl-file>
-+        Use the Certificate Revocation List (CRL) file <crl-file> in PEM format.
-+      crl-dir <dir>
-+        Use CRL files from directory <dir>. It contains CRL files in PEM
-+        format and each file contains a CRL. The files are looked up
-+        by the issuer name hash value. Use the c_rehash utility
-+        to create necessary links.
-+      need-peer-eap
-+        If the peer doesn't ask us to authenticate or doesn't use eap
-+        to authenticate us, disconnect.
-+
-+    Note:
-+      password-encrypted certificates can be used as of v0.94 of this
-+      patch. The password for the eap-tls.key file is specified using
-+      the regular
-+          password ....
-+      statement in the ppp options file, or by using the appropriate
-+      plugin which supplies a 'eaptls_passwd_hook' routine.
-+
-+5. Connecting
-+
-+    If you're setting up a pppd server, edit the EAP-TLS configuration file
-+    as written above and then run pppd with the 'auth' option to authenticate
-+    the client. The EAP-TLS method will be used if the other eap methods can't
-+    be used (no secrets).
-+
-+    If you're setting up a client, edit the configuration file and then run
-+    pppd with 'remotename' option to specify the server name. Add the
-+    'need-peer-eap' option if you want to be sure the peer ask you to
-+    authenticate (and to use eap) and to disconnect if it doesn't.
-+
-+6. Example
-+
-+    The following example can be used to connect a Linux client with the 'pptp'
-+    package to a Linux server running the 'pptpd' (PoPToP) package. The server
-+    was configured with a certificate with name (CN) 'pptp-server', the client
-+    was configured with a certificate with name (CN) 'pptp-client', both
-+    signed by the same Certificate Authority (CA).
-+
-+    Server side:
-+      - /etc/pptpd.conf file:
-+          option /etc/ppp/options-pptpd-eaptls
-+          localip 172.16.1.1
-+          remoteip 172.16.1.10-20
-+      - /etc/ppp/options-pptpd-eaptls file:
-+          name pptp-server
-+          lock
-+          mtu 1500
-+          mru 1450
-+          auth
-+          lcp-echo-failure 3
-+          lcp-echo-interval 5
-+          nodeflate
-+          nobsdcomp
-+          nopredictor1
-+          nopcomp
-+          noaccomp
-+
-+          require-eap
-+          require-mppe-128
-+
-+          crl /home/janjust/ppp/keys/crl.pem
-+
-+          debug
-+          logfile /tmp/pppd.log
-+
-+      - /etc/ppp/eaptls-server file:
-+           * pptp-server - /etc/ppp/pptp-server.crt /etc/ppp/ca.crt /etc/ppp/pptp-server.key *
-+
-+      - On the server, run
-+          pptdp --conf /etc/pptpd.conf
-+
-+    Client side:
-+      - Run
-+          pppd noauth require-eap require-mppe-128 \
-+            ipcp-accept-local ipcp-accept-remote noipdefault \
-+            cert  /etc/ppp/keys/pptp-client.crt \
-+            key   /etc/ppp/keys/pptp-client.key \
-+            ca    /etc/ppp/keys/ca.crt \
-+            name pptp-client remotename pptp-server \
-+            debug logfile /tmp/pppd.log
-+            pty "pptp pptp-server.example.com --nolaunchpppd"
-+
-+    Check /var/log/messages and the files /tmp/pppd.log on both sides for debugging info.

-Subject: [PATCH] pppd: Use openssl for the DES instead of the libcrypt / glibc
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-[https://github.com/paulusmack/ppp/commit/3c7b86229f7bd2600d74db14b1fe5b3896be3875]
-
-It seems the latest glibc (in Fedora glibc-2.27.9000-12.fc29) dropped
-libcrypt.  The libxcrypt standalone package can be used instead, but
-it dropped the old setkey/encrypt API which ppp uses for DES.  There
-is support for using openssl in pppcrypt.c, but it contains typos
-preventing it from compiling and seems to be written for an ancient
-openssl version.
-
-This updates the code to use current openssl.
-
-[paulus@ozlabs.org - wrote the commit description, fixed comment in
- Makefile.linux.]
