2017-05-12	built_in: don't redefine memcpy/memset	Tobias Klauser	1	-3/+3
	Redefining memset/memcpy causes problems when building with fortified headers on Alpine Linux. Instead of uncoditionally defining these, explicitely use fmemcpy/fmemset in performance critical paths and otherwise let the compiler decide about optimizations. Fixes #173 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-10-21	csum: Don't drop const qualifier during cast	Tobias Klauser	1	-3/+3
	Don't drop const qualifier during cast to void * Found by compiling with -Wcast-qual. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2015-11-09	csum: Remove unused parameter from calc_csum()	Tobias Klauser	1	-2/+1
	The `ccsum' parameter to calc_csum() is never used and is set to 0 by all callers. There's no reason to keep it, so remove it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2015-10-14	csum: Remove unnecessary memset in p4_csum()	Tobias Klauser	1	-4/+3
	No need to memset the IPv4 pseudo header to 0 as all its members will explicitly be set. Also reorder the setting of the pseudo header to match the order of the fields. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2015-10-13	trafgen: Add checksum helpers for TCP/UDP over IPv6	Tobias Klauser	1	-0/+28
	Add the csumudp6 and csumtcp6 helper functions in order to simplify checksum generation for TCP/UDP packets sent over IPv6. trafgen example for TCP over IPv6: { /* MAC Destination / fill(0xff, 6), / MAC Source / 0x00, 0x02, 0xb3, drnd(3), / IPv6 Protocol / c16(0x86DD), / Version, Traffic Class, Flow Label / 0b01100000, c8(0), c16(0), / Payload Length / c16(54), / Next Header (TCP) / c8(6), / Hop Limit / c8(64), / Source IPv6 / 0xfe, 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xba, 0xac, 0x6f, 0xff, 0xfe, 0xa4, 0x12, 0xe3, / Destination IPv6 / 0xfe, 0x80, 0x82, 0x2e, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xde, 0xff, 0xfe, 0x00, 0x06, 0xde, / TCP Source Port / c16(55042), / TCP Destination Port / c16(55043), / TCP Sequence Number / drnd(4), / TCP Ackn.

2014-09-12	csum: Use ISO C fixed width types	Tobias Klauser	1	-22/+22
	Use the ISO C fixed width types from stdint.h instead of the self-defined Linux types. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-04	misc: cleanup header comments	Daniel Borkmann	1	-6/+0
	Remove header comments where appropriate. And also clean up colorize a bit. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-24	misc: fix some minor compile warnings all over	Daniel Borkmann	1	-1/+2
	Some regarding unused parameter, some regarding signed/unsigned comparison. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15	all: import netsniff-ng 0.5.8-rc0 source	Daniel Borkmann	1	-0/+179
	We decided to get rid of the old Git history and start a new one for several reasons: ) Allow / enforce only high-quality commits (which was not the case for many commits in the history), have a policy that is more close to the one from the Linux kernel. With high quality commits, we mean code that is logically split into commits and commit messages that are signed-off and have a proper subject and message body. We do not allow automatic Github merges anymore, since they are total bullshit. However, we will either cherry-pick your patches or pull them manually. ) The old archive was about ~27MB for no particular good reason. This basically derived from the bad decision that also some PDF files where stored there. From this moment onwards, no binary objects are allowed to be stored in this repository anymore. The old archive is not wiped away from the Internet. You will still be able to find it, e.g. on git.cryptoism.org etc. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
