2013-05-29ifpps: Properly zero out allocated statsTobias Klauser1-1/+1
The dynamically allocated members of struct ifstat have an entry for each CPU. Properly consider this when resetting the stats in the STATS_ZERO1 macro. Reported-by: Daniel Borkmann <borkmann@iogearbox.net> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-05-29ifpps: support mq devices in /proc/interruptsDaniel Borkmann1-2/+7
/proc/interrupts can have such a structure ... 98: 35 0 2902361 PCI-MSI-X eth1-0 106: 61 11 3841 PCI-MSI-X eth1-1 114: 28 0 61452 PCI-MSI-X eth1-2 122: 24 1586 22 PCI-MSI-X eth1-3 130: 2912 0 337 PCI-MSI-X eth1-4 138: 21 0 28 PCI-MSI-X eth1-5 146: 21 0 56 PCI-MSI-X eth1-6 154: 34 1 1 PCI-MSI-X eth1-7 ... and will not count all IRQs for eth1-*. Thus change it to sum up multiple entries. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-29ifpps: also show total number of cpusDaniel Borkmann1-2/+2
Just a minor change to also show the total number of cpus in the headline. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-29ifpps: remove unused function snr_to_strDaniel Borkmann1-16/+0
It's not used anywhere anymore, so remove it. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-27ifpps: Use strtoul() to convert unsigned valueTobias Klauser1-1/+1
The refresh interval can only be positive and is stored in an uint64_t, so use strtoul() to convert it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-05-27ifpps: minor: minor output formatting adaptionDaniel Borkmann1-2/+2

2013-05-27ifpps: fix bug_on trigger when parsing irq numberDaniel Borkmann1-10/+18
When parsing irq numbers on e.g. 24 CPU machines, procfs lines can get very long, so our static temporary buffer size will fail here with: Assertion `!(stats->irq_nr == 0)' failed. So allocate it relative to the CPU number. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-27ifpps: beautify output with > 10 cpusDaniel Borkmann1-15/+26
I've tested it on a 24 CPU machine, and it does not look so nice if there's different padding along the lines. This patch fixes it. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-27ifpps: Add myself to the copyright holders in --version/--helpTobias Klauser1-0/+2
Add my name to the ouput of --version and --help. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-05-27ifpps: Don't assume a maximum of 32 CPUsTobias Klauser1-30/+158
There are people with machines containing far more than 32 CPUs. In their case ifpps didn't work until now because of a limitation to 32 CPUs. Rework ifpps to support an arbitrary number of CPUs. In order to still remain within the display space, if more than 10 (TOP_CPUS) CPUs are available, only the 10 top hitting (in terms of usr and sys time or irqs respectively) are displayed.

2013-05-25ifpps: Convert mem_free/mem_total members of struct ifstat to uint64_tTobias Klauser1-3/+4
Memory usage can never be negative, so make these members unsigned. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-05-23make: include build nameDaniel Borkmann1-1/+1
Include long version string into tools when called with --version. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-17ifpps: Add __noreturn attribute to exiting functionsTobias Klauser1-2/+2
Add the __noreturn attribute to all functions which wont return but call die() themselves to exit(). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-05-15man: trafgen: Minor fixesTobias Klauser1-2/+2
Replace "on default" by "by default", make it a bit more clear what the seed in the -E/--seed option is for and mention exit after display of information on --version and --help. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-03-16ifpps: remove state from enum, since never usedDaniel Borkmann1-2/+1
We do not assign or use this particular state, so just remove it from the enum. We continue anyway in the while loop in that case. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-16misc: remove dead/unreachable code from switch statementsDaniel Borkmann1-2/+0
Remove various unreachable sections from the switch statements. This was detected by the coverty scanner. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+949
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>
