2013-06-14sock: Check return value of setsockopt() in set_tcp_nodelay()Tobias Klauser1-2/+5
Check the return value of setsockopt() and panic in case it is not 0, as in the other setsockopt() wrapper functions. This issue was discovered by the Coverity scanner. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-14dissector: icmpv6: Fix yet another possible null pointer dereferenceTobias Klauser1-3/+11
THe Coverity scanner discovered yet another possible null pointer dereference. Fix it by checking the return value of pkt_pull(). Also remove some trailing whitespaces in the region. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13flowtop: Remove unnecessary bug_on() and rework presenter_screen_init()Tobias Klauser1-8/+9
The screen pointer can never be NULL, since initscr() exits the process in case of an error. Thus the bug_on() check can be omitted. Also rework presenter_screen_init() - where initscr() is called - to return the pointer. This will also silence a Coverity scanner error (even though it isn't actually one). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13dissector: icmpv6: Fix another possible null pointer dereferenceTobias Klauser1-1/+9
This was missing in the previous commit 8b824423 ("dissector: icmpv6: Fix possible null pointer dereferences"), so fix the possible null pointer dereference now. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13dissector: ip_auth_hdr: Fix possible null pointer dereferenceTobias Klauser1-2/+11
Fix an unconditional dereference of a pkt_pull() return value to prevent dereferencing a null pointer. This was found by the Coverity scanner. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13dissector: icmpv6: Fix possible null pointer dereferencesTobias Klauser1-8/+56
The Coverity scanner found several possible null pointer dereferences in the ICMPv6 dissector. These are all related to not checking the return value of pkt_pull(). Sometimes pkt_pull(()) is called iteratively based on a length value in the encountered packet, so this could possibly be hit in case an invalid packet is crafted accordingly. Fix all by checking the return value of pkt_pull() consistently. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13dissector: eth: Free allocated record if line is skippedTobias Klauser1-2/+6
We would currently leak the record in case we skip a line, fix this by xfree()ing the memory in these cases. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13oui: Free allocated record if line is skippedTobias Klauser1-2/+6
We would currently leak the record in case we skip a line, fix this by xfree()ing the memory in these cases. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13dissector: eth: Make port file parsing more robustTobias Klauser1-4/+11
Follow commit bdb9efef ("oui: Make parsing of oui.conf more robust") and make parsing the upd.conf, tcp.conf and ether.conf files more robust against format flaws. ALso here, in the worst case, we would end up dereferencing a null pointer. The null pointer dereference was found by the Coverity scanner. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-13oui: minor: Fix commentsTobias Klauser1-1/+2
Make comments related to skipping of lines a bit clearer. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

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

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>
