cdb793f687 Remove use of bufferevent and eventbuffers, use our own buffering instead. 2011-05-14 19:20:56 +02:00
Guus Sliepen
f431fcb35f Add simple buffer management code.
Libevent 2.0's buffer code is not completely backward compatible with 1.4's.
In order to not (mis)use it anymore, we implement it ourselves. The buffers
are automatically expanding when necessary. When consuming data from the
buffer, no memmove()s are performed. Only when adding to the buffer would
write past the end do we shift everything back to the start.

03b7118139 Reorder checks for libraries to allow ./configure LDFLAGS=-static.
OpenSSL depends on libdl and libz. When linking dynamically, libcrypto will
automatically link with the other two libraries.  However, when linking
statically, these libraries need to be specified explicitly while linking.  By
moving the autoconf checks for libdl and libz before those for libcrypto, we
ensure the latter test will be done with the proper libraries.

6e6b037ef4 Check for EVP_EncryptInit_ex instead of SHA1_Version in OpenSSL.
The latter function disappeared, and wasn't actually used in tinc, so now we
check on a function that we do use.

257cb6ac60 Always use the default signal handler for ABRT signals.
This will allow coredumps to be generated when tinc is daemonized.
Also add the -kABRT option.

eacb5a28fb Increase threshold for detecting two nodes with the same Name.
In commit 4a21aabada, code was added to detect
contradicting ADD_EDGE and DEL_EDGE messages being sent, which is an indication
of two nodes with the same Name connected to the same VPN.  However, these
contradictory messages can also happen when there is a network partitioning. In
the former case a loop happens which causes many contradictory message, while
in the latter case only a few of those messages will be sent. So, now we
increase the threshold to at least 10 of both ADD_EDGE and DEL_EDGE messages.

0aa86d4b8b Do not set indirect flag on edges from nodes with multiple addresses.
Since tinc now handles UDP packets with a different source address and port
than used for TCP connections, the heuristic to treat edges as indirect when
tinc could detect that multiple addresses were used does not make sense
anymore, and can actually reduce performance.

7cf68b5e35 Prevent anything from updating our own UDP address.
Because we don't want to keep track of that, and this will cause the node
structure from being relinked into the node tree, which results in myself
pointing to an invalid address.

cdbbbfabea Fix spurious misidentification of incoming UDP packets.
When a UDP packet was received with an unknown source address/port, and if it
failed a HMAC check against known keys, it could still incorrectly assign that
UDP address to another node. This would temporarily cause outgoing UDP packets
to go to the wrong destination address, until packets from the correct address
were received again.

instead of using a tun/tap device.

6a51d89cf7 Replace bogus #else with #endif.
Found by cppcheck, which complained about lenin not being initialized, but the
real problem is that reading packets would fail when using code compiled with
--tunemu on a normal tun device.

f99661a4ca Always send MTU probes at least once every PingInterval.
Before, if MTU probes failed, tinc would stop sending probes until the next
time keys were regenerated (by default, once every hour).  Now it continues to
send them every PingInterval, so it recovers faster from temporary failures.

a91bf2dfcd Quit when there are too many consecutive errors on the tun/tap device.
Although transient errors sometimes happen on the tun/tap device (for example,
if the kernel is temporarily out of buffer space), there are situations where
the tun/tap device becomes permanently broken. Instead of endlessly spamming
the syslog, we now sleep an increasing amount of time between consecutive read
errors, and if reads still fail after 10 attempts (approximately 3 seconds),
tinc will quit.

aca70cd3c3 Treat netname="." in a special way.
Treat netname "." in a special way as if there was no netname
specified.  Before, f.e. tincd -n. -k didn't work as it tried
to open /var/run/tinc-.pid.  Now -n. works as if there was no
-n option is specified.
