2020-05-04proto_lldp: prevent accidental out of bounds memory accessNathaniel Ferguson1-1/+5
Added an integer arithmetic check prior to performing arithmetic to prevent accidental out of bounds memory access. Signed-off-by: Nathaniel Ferguson <nathaniel@leapfrog.foundation> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2020-05-04proto_lldp: fix pointer increment in LLDP_TLV_SYSTEM_CAP caseNathaniel Ferguson1-1/+1
Fixed a typo wherein a pointer was incremented by sizeof(uint32_t) after reading sizeof(uint16_t) and before reading another sizeof(uint16_t). In essence a potential out of bounds memory access (read) due to improper increment of pointer Signed-off-by: Nathaniel Ferguson <nathaniel@leapfrog.foundation> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2020-05-04proto_lldp: Check inet_ntop() return valuesNathaniel Ferguson1-3/+11
Make netsniff error out of a recv routine if calls to inet_ntop() fail by adding return value checks.

When testing trafgen with the following example from the man page the error message "Failed to parse MAC address 11:22:33:44:55:66" is printed. trafgen -o lo --cpus 1 -n 3 '{ eth(da=11:22:33:44:55:66, da[0]=dinc()), tcp() }' Turns out errno was not cleared before str2mac() called sscanf().

Jon's name was spelled wrong in .mailmap in commit 79608cdc169b ("AUTHORS: auto-generate from commit log") and thus ended up being wrong in the AUTHORS file since we started auto-generating it. Sorry about that! Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2019-04-10trafgen: fix -t 0 option to use sendtoQuentin Chateau1-5/+0
Currently, using -t 0 option calls shaper_set_delay with 0 sec and 0 ns, which results in sh->type to be SHAPER_NONE. This in turn causes trafgen to use TX_RING. Expected behavior, from "man trafgen": If this option is given, then instead of packet(7)'s TX_RING interface, trafgen will use sendto(2) I/O for network packets, even if the argument is 0. This patch forces sh->type to be set to SHAPER_DELAY even if the delay is 0. shaper_delay already handles the case where sh->type is SHAPER_DELAY and the delay is 0.

2019-03-06Build system: Use GZIP_ENV instead of GZIPDaniel Roggow2-2/+2
Older versions of gzip assume the GZIP environment variable contains flags[1]. Building netsniff-ng on a system with such a version of gzip will yield the following error: INST netsniff-ng/netsniff-ng gzip -9 -c netsniff-ng.8 > netsniff-ng/netsniff-ng.8.gz gzip: gzip: No such file or directory A practical alternative to redefining GZIP in the Makefile seems to be to use the GZIP_ENV make variable[2] instead. [1] The GZIP environment variable was deprecated in gzip version 1.7. See https://www.gnu.org/software/gzip/manual/html_node/Environment.html and https://git.savannah.gnu.org/cgit/gzip.git/tree/NEWS for more information.

2018-11-30astraceroute: Fix for reading mirrors from fileMandar Gokhale1-2/+2
If the file that GeoIP mirror addresses are being read from lacks a terminating newline, then the code that reads them in exhibits an off-by-one error. Example of such a file: $ xxd /etc/netsniff-ng/geoip.conf 00000000: 6765 6f6c 6974 652e 6d61 786d 696e 642e geolite.maxmind. 00000010: 636f 6d com Fix this by explicitly getting the part of the string before the newline using `strcspn`.
