2013-06-12netsniff-ng: walk_t3_block: prevent fd from double closeDaniel Borkmann1-4/+4
Only close the very first pcap file of multi-pcap files once, and not once during next_multi_pcap_file and once during exit. Discovered by Coverty scanner. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-12flowtop: set bug if screen is NULLDaniel Borkmann1-0/+2
If this is ever the case, bail out. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-12cpus: let it always return an unsigned int and bail out on errorDaniel Borkmann1-4/+16
In case of an error, just panic, to make sure we always get a val >= 1. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-12stun: close socket before returning in error caseDaniel Borkmann1-2/+5
Do not leak the socket resource when bailing out in error case. Found by the coverty scanner. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-12keypair: add missing include fileDaniel Borkmann1-0/+1
Include curve.h so that it also finds the selftest. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-12stun: memset saddr before bindingDaniel Borkmann1-1/+2
We need to zero out data before we actually do the bind, otherwise uninitialized crap can be in saddr. Found by coverty scanner. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11man: astraceroute: minor: remove two trailing whitespacesDaniel Borkmann1-2/+2
Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11man: improvements to astraceroute.8, inconsistent use of and ''Stephen Wadeley1-7/+7
Signed-off-by: Stephen Wadeley <swadeley@redhat.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11man: improvements to language for astraceroute.8Stephen Wadeley1-28/+30
Signed-off-by: Stephen Wadeley <swadeley@redhat.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11keypair: do selftest before generating and verifying keypairDaniel Borkmann1-0/+4
Be paraniod and make a selftest. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11curve: move selftest to own fileDaniel Borkmann5-79/+87
Move the curve selftest to its own file. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11irq: do not process non-existant irq number of loDaniel Borkmann1-0/+2
Prevent IRQ affinity restore of lo device, since we do not collect it and since it doesn't have a IRQ number. This fixes a warning on trafgen and netsniff-ng when exiting. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11taia: minor: add comment about windowDaniel Borkmann1-1/+1
Add a small comment about the 700ms. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-11oui: Make parsing of oui.conf more robustTobias Klauser1-4/+10
In the unlikely case of the oui.conf file not conforming to the required format (e.g. by the user supplying one by himself), we would end up - in the worst case dereferencing a null pointer, if the condiition (ptr = strstr(buff, ", ")) is false. Thus make the entire parsing a bit more robust and just ignore lines not following the required format. The null pointer dereference was found by the Coverity scanner. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-10taia: minor: small cleanup and commentDaniel Borkmann1-1/+4
Put a comment there explaining why we randomize atto. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-10ifpps: Remove unused 'forks' member from struct ifstatTobias Klauser1-4/+1
We never use or report it anywhere, so remove it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09ifpps: minor: fix ncurses alignmentDaniel Borkmann1-3/+3
Since we've added '+'/'-' for max/min CPU values, we also need to shift once whitespace to the left to properly align ncurses display again. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-09ifpps: Rename cpu number parameter to stats_top()Tobias Klauser1-2/+2
This is not the top number of CPUs but the total number. Rename the variable to not confuse this. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09man: ifpps: Reword a few sentences or make them shorterTobias Klauser1-6/+6
Fix some minor nits in the description part and remove a superfluous comma in the description of option -d/--dev. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09ifpps: Report more detailed memory stats and number of total processesTobias Klauser1-10/+88
Instead of just giving the percentage of memory usage, report the total, used, active and inactive memory values. Also report total, free and cached for swap. Instead of reporting the memory in the 'sys' line add two new lines for these reports and use the free space to report the total number of processes. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09ifpps: Don't calculate diff for stats values not used for relative valuesTobias Klauser1-4/+0
These stats values are not reported anywhere in relative terms, so it makes no sense to calculate the difference for them. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09ifpps: Don't diff tx_bytes twiceTobias Klauser1-1/+0
It's sufficient to calculate the difference of tx_bytes only once. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09ifpps: Don't re-initialize stats value index counter in CSV modeTobias Klauser1-1/+1
In case we add new stats values, j might be higher already when entering the loop. As j will have the proper number anyway, there is no point in re-initializing. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-09mausezahn: man: fixed typo and minor sentence editsJon Schipp1-13/+12
That's a first part of the manpage edit for now. Signed-off-by: Jon Schipp <jonschipp@gmail.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-08bpfc: also allow to load skb len into XDaniel Borkmann1-0/+2
This functionality is available in the kernel, so make it also available for use in bpfc. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-06ifpps: Also display min hitter for IRQsTobias Klauser1-23/+50
Also display the least heavy hitter for the relative and absolute IRQ list. Also check that the number passed with -n is actually 1 or larger. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-06ifpps: Always display the least heavy hitter CPUTobias Klauser2-19/+44
Along with the topmost heavy hitters, we always display the least heavy hitter (unless there's only 1 CPU). This is not influenced by the -n command line parameter, so also display the according additional CPU in the header line. Also update the manpage accordingly. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-04zsh: add zsh completion function for mausezahnHideo Hattori1-0/+67
Initial zsh autocompletion support for mausezahn! Signed-off-by: Hideo Hattori <hhatto.jp@gmail.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04curve: also really remove taia functions from hereDaniel Borkmann1-43/+3

2013-06-04taia: move taia evaluation out of curve.Daniel Borkmann4-1/+36
This is not really related to curve functions, so move it out from there. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04curve: move taia related functions into own headerDaniel Borkmann2-139/+160
Move them into a separate header, structures and inline functions, since they are more or less independant of curve.h. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04bpf: split up instructions and extensions from headerDaniel Borkmann3-98/+107
Move them into a separate header file, so that it is more clean. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04ioops: fix build error by renaming 'len' variableDaniel Borkmann1-2/+2
Argh, forgot to rename variables in read_blob_or_die/write_blob_or_die. ioops.c: In function ‘read_blob_or_die’: ioops.c:105:30: error: ‘len’ undeclared (first use in this function) ioops.c:105:30: note: each undeclared identifier is reported only once for each function it appears in ioops.c: In function ‘write_blob_or_die’: ioops.c:116:31: error: ‘len’ undeclared (first use in this function) make: *** [netsniff-ng/ioops.o] Error 1 Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

2013-06-04crypto: add crypto header with includes and definesDaniel Borkmann6-34/+26
Add another header with includes and defines, so that we can reduce double-definitions, and shorten long text strings. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04misc: cleanup header commentsDaniel Borkmann19-115/+12
Remove header comments where appropriate. And also clean up colorize a bit. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04tstamping: add header file for packet timestampingDaniel Borkmann3-11/+9
Better add a header file for this, so that we do not need to have it in multiple places declared. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04rnd: move entropy source definition to rndDaniel Borkmann3-10/+11
It's better off there anyway. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
