2013-09-09ifpps: correct calculation of line rate percentageTobias Klauser1-2/+2
The line rate is given in Mbit rather than MiB (in which {rx,tx}_bytes were converted). Correct the calculation by converting {rx,tx}_bytes to Mbit: (n bytes * 8 bits per byte) / 1000^2 = (n bytes) / 125000 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2013-09-05ifpps: make display of line rate percentage optionalTobias Klauser1-4/+11
In order to not to clutter the display too much, make the display of the percentage of the theoretical line rate dependent on a command line option. Suggested-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-09-04ifpps: show percentage of theoretical line-rateTobias Klauser1-0/+17

2013-09-04ifpps: Reuse device bitrate for screen_header()Tobias Klauser1-3/+2
Instead of issuing another call to device_bitrate(), reuse the the value acquired in screen_update() and pass it to screen_header(). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-09-03bpf: ldi,ldxi: allow for '#' prefix in numbersDaniel Borkmann1-2/+6
For consistency, allow for '#' prefix in numbers, which we currently do not do. So keep old mode as compatibility to not break current programs, and add new one with '#' prefix. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-09-02netsniff-ng: Remove unnecessary fmemset() of struct statTobias Klauser1-1/+0
The struct stat is filled by the call to stat(2) in the next line, so there is no need to explicitely set it to 0 before. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-09-01man: netsniff-ng: add note about netsniffJon Schipp1-0/+4
Add a note to the man-page that there's a other tool that is unrelated to netsniff-ng. Signed-off-by: Jon Schipp <jonschipp@gmail.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-08-30netsniff-ng: Simplify dump file creation logicTobias Klauser1-9/+5
Instead of using goto, just check stats if stat() returned 0 and used ctx->dump_dir afterwards. This makes the logic a bit easier to follow. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-08-30ifpps: Skip reading IRQ number from /proc/interruptsTobias Klauser1-7/+5
We don't use the IRQ number we read from /proc/interrupts, so just skip it while reading. This also allows us to drop the irq_nr member from struct ifstat. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-08-29ifpps: Don't bug out if interface went downTobias Klauser1-2/+5
In case the interface ifpps is running on went down, ifpps bugged out because the stats didn't look plausible anymore, due to the IRQ count being reset: ifpps: ifpps.c:563: stats_diff: Assertion `!((new->irqs[i] - old->irqs[i]) > (new->irqs[i]))' failed Fix this by setting the difference to 0 in this case. ifpps will thus display a irqs/t value of 0 instead of bugging out. This fixes #74. Reported-by: Jon Schipp <jonschipp@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-08-29ifpps: Use unsigned int to store number of cpusTobias Klauser1-23/+24
The number of CPUs can never be negative and get_number_cpus() returns unsigned int too, so consistently conver all variables holding a CPU number or number of CPUs to type unsigned int. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2013-08-21ring_{rx,tx}: verbose: output version and v3 specific infoDaniel Borkmann2-4/+10
Kevin says: With netsniff-ng 0.5.8-rc2+, when I run the below packet capture session, the output seems to imply that 64K of memory is being allocated per frame, which does not look like what I want since my interface MTU is only 1500. This appears to be severely limiting the number of frames I can fit into my packet capture ring. As TPACKET_V3 is used in capturing to pcap files, frames are written continuously to the ring, thus the above will give a wrong impression to the user. Therefore, output such information in verbose mode differently when TPACKET_V3 is being used, as it works block-wise.

2013-08-21build: minor: Mention proper versioned tag in release announcementTobias Klauser1-1/+1
The tags created by the 'release' target have a 'v' prefix, so add it to the verification command mentioned in the generated release message. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-08-21configure: minor: Rephrase and reformat some messagesTobias Klauser1-12/+11

2013-08-21astraceroute: Support binding to a specific IP address.Oliver Smith2-4/+32
In a situation where the IP that you wish to use as the source address differs from the interface it needs to be sent from, it is now possible to manually specify an address to bind to whilst still being able to specify the physical interface to send from.

2013-08-20configure: allow trafgen build when only TPACKET_V2 is availableDaniel Borkmann2-0/+17
On machines like RHEL6 that do not have support for TPACKET_V3, we should still allow at least trafgen to be built for network testing. Thus, do something useful with the TPACKET_V3 configure check and comment out in ring.h relevant structures. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-08-19netsniff-ng: poll: don't panic on EINTRDaniel Borkmann1-4/+8

2013-08-12build: Add Makefile target for Coverity scannerTobias Klauser3-0/+24
Add a Makefile target to build and upload a snapshot of netsniff-ng to the Coverity scanner. The variables COV_EMAIL and COV_PASSWD need to be set accordingly: make coverity COV_EMAIL=tklauser@distanz.ch COV_PASSWD=... Currently the sub-make which is part of the cov-built call issues warnings about undefined variables from the template. This can be ignored, the build works just fine. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-08-12netsniff-ng: Check return value of poll()Tobias Klauser1-3/+7
The return value of two calls to poll() are never check, despite the (unlikely) possibility of them returning an error, fix it by checking the return value and panic()ing on error. This issue was discovered using the Coverity scanner. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
