net/if.h and linux/if.h headers conflict with each other as of linux
6.3 and glibc 2.37 headers:
In file included from /usr/include/linux/icmp.h:23,
from icmp.c:5:
/usr/include/net/if.h:44:5: error: redeclaration of enumerator ‘IFF_UP’
44 | IFF_UP = 0x1, /* Interface is up. */
| ^~~~~~
/usr/include/linux/if.h:83:9: note: previous definition of ‘IFF_UP’ with type ‘enum net_device_flags’
83 | IFF_UP = 1<<0, /* sysfs */
| ^~~~~~
icmp.c gets net/if.h from l2tpns.h, and linux/if.h from linux/icmp.h.
In our case, we do not need to use the linux headers at all here as we
are doing normal userspace things: just use glibc headers all the way.
This has been tested with kernel 3.2 / glibc 2.13 headers, so it's
probably fine. (l2tpns does not currently build with musl)
- Call sessionshutdown() when a tunnel is dropped rather than
sessionkill() to ensure that RADIUS stop records are sent.
- Cleanup: make a bunch of global functions/variables static.
This supports privileged and unprivileged commands, as well as a configuration
mode
* Add help for all cli commands
* Add "show version" command
* Fix uptime counter display
* Fix nasty bug where cluster basetime can be set to 0 when sending initial
heartbeat
* Don't rmmod ip_conntrack, as this can take a lot of time
* Re-order logging in routeset such that the action is given before any error
* Use the correct gateway address when deleting routes
* Remove any routes when address changes
* Require authentication if telnet from remote ip
* Require enable password always
* Return error if show pool done on slave
* We MUST immediately exit if we're the wrong master!
- Major release
- Completely replace active/standby clustering with a new peer-to-peer
clustering method which allows much greater throughput and is a lot more fault
tolerant
- Add internal tbf implementation for throttling without relying on tc and
kernel HTB
- Add support for iBGP and eBGP to advertise routes
- Add cli commands "show cluster", "show bgp", "show ipcache", "show throttle",
"show tbf", "suspend bgp", "restart bgp", "show user"
- Interception destination must be set per-user
- If SMP machine, allow use of SCHED_FIFO, which should improve performance
- Added config option to send GARP at startup
- Added plugin_become_master and plugin_new_session_master plugin hooks
- Remove useless sessionsendarp(). This isn't needed now that we are using TUN
instead of TAP.
- ICMP rate limiting so not every unreachable packet is replied with an ICMP
unreachable message
- mangle table is not required on anything but the cluster master, so slaves
will drop the mangle table and attempt to unload the ip_conntrack module
- Statically assigned IP addresses (by Radius) work now
- Add -d command-line flag to detach and become a daemon
- Configuration file is now "/etc/l2tpns/startup-config"
- Reduced MIN_IP_SIZE to 0x19 to stop a pile of Short IP warnings
- Resend initial IPCP request until it's acknowleged by the client
- Better radius session cleanup logic
- Many miscellaenous bugfixes and performance enhancements
- Thanks to Michael O'Reilly and Brendan O'Dea for most of these new features
- Change all strcpy() calls to strncpy() to avoid buffer overflow potential
- Add ICMP host unreachable support
- Logging to syslog if log_file = "syslog:facility"
- Now requires libcli 1.5
- All configuration moves to a config structure
- Ability to modify and write config on the fly through command-line interface
- Config file support is removed, and now handled by the cli
- Show hostname in cli prompt
- Keep current state type for tunnels
- Add uptime command do CLI, which also shows real-time bandwidth utilisation
- Add goodbye command to cluster master, which forces droppping a slave
- Cache IP address allocation, so that reconnecting users get the same address
- Fix tunnel resend timeouts, so that dead tunnels will be cleaned up
- Allocate tunnels and radius without using a linked list which had issues
- Fix some off-by-one errors in tunnel and session and radius arrays
- Save and reload ip address pool when dieing
- Check version and size of reloaded data when restarting
- Remove plugin_config support
- Remove old support for TBF which didn't work anyway. HTB is required to do throttling now.
- Add COPYING and Changes files
