2015-07-13flowtop: Fix flows disappearingVadim Kochan1-1/+3
While removing flow which is pointed by 'head' then head is set to NULL and all the list disappears, so fixed by set removing flow next entry to list 'head'. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
2015-03-23flowtop: Print error cause if errno is set when panicVadim Kochan1-5/+5

2015-03-20flowtop: Don't init screen until collector is readyVadim Kochan1-0/+9
In case if main thread already initialized screen but then collector called panic, the process exits but console stays with the same colored screen and shifted shell prompt. Fixed by adding conditional variable locking. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-12-12all: Reduce amount of empty liens in usage and version output a bitTobias Klauser1-5/+5
No need for some of the empty lines, remove them to make the output a bit denser. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-09-08flowtop: Use integer conversion to determine PID proc entriesTobias Klauser1-13/+20
Try to convert the directory entry name to an unsigned integer with strtoul() instead of using strspn() to determine if a proc entry is a PID. If it is a valid PID (i.e. strtoul returned a value != 0), we can directly use it to pass into walk_process() and there set flow_entry->proc_num. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-09-08flowtop: Simplify entry skip logicTobias Klauser1-10/+5
Instead of testing three skip conditions for every entry, make use of the short-circuit evaluation of the boolean OR operator to only test as few conditions as necessary. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-09-05flowtop: Don't duplicate copyright/bug report/license stringTobias Klauser1-16/+12
Move the copyright/bug report/license string to an own constant and use it for the output of help() and version() to avoid duplication and prevent the strings from getting out of sync. This makes the text section of flowtop.o slightly smaller: before: text data bss dec hex filename 15601 4 48 15653 3d25 flowtop/flowtop.o after: text data bss dec hex filename 15228 4 48 15280 3bb0 flowtop/flowtop.o Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-07-23build: flowtop: Only build ioops with GeoIP support enabledTobias Klauser1-1/+0
Follow commit 9ad7f8882097 ("build: astraceroute: Only build ioops with GeoIP support enabled"). The ioops module is only needed in geoip.o, thus make it dependent on CONFIG_GEOIP. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-06-13lookup: Move UDP/TCP port and Ethernet type lookup into own moduleTobias Klauser1-3/+5
Up to now, the lookup of TCP/UDP port names and Ethernet types was tightly integrated with the dissector infrastructure, since it is its main user. However, flowtop also makes use of the name lookup functionality without needing the actual dissector infrastructure. Thus, the basic dissector infrastructure also needs to be linked into flowtop without actually being used. Fix this by extracting the port/ethertype lookup into an own module which can then be used either directly (for flowtop) or as part of the dissector infrastructure (for netsniff-ng). This also reverts the quick & dirty fix introduced in commit f3322c6 ("flowtop: Include netlink dissector to fix build temporarily"). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-05-27geoip: Pass struct sockaddr_in{,6} as pointer instead of by valueTobias Klauser1-4/+4
Change the interface to the geoip_* functions to take a pointer to a struct sockaddr_in{,6} instead of the struct itself. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-05-27flowtop: Constify function parameter in walk_process()Tobias Klauser1-1/+1
Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-05-03all: Use macros for printf/scanf format specifiersJames McCoy1-4/+5
Any types that are fixed width should use the standard format specifier macros (PRI... for printf-type functions, SCN... for scanf-type functions) to ensure proper data access. Prior to this ifpps was crashing in 32-bit environments due to the following call mvwprintw(screen, (*voff)++, 2, "%s,%s %s (%s%s), t=%lums, cpus=%u%s/%u" " ", uts.release, machine, ifname, drvinf.driver, buff, ms_interval, top_cpus, top_cpus > 0 && top_cpus < cpus ? "+1" : "", cpus); since ms_interval is a uint64_t but %lu expects an unsigned long, which is only 32 bits.

2014-02-22flowtop: Exit gracefully for all possible termination signalsTobias Klauser1-0/+4
Handle all termination signals that we're allowed to handle (SIGKILL can't be handled) in order to exit gracefully in any regular termination case. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-07-29flowtop: Fix compiler warningsTobias Klauser1-2/+3
Fix the following compiler warnings that occur when building with "-W -Wall -Wextra": flowtop.c: In function ‘walk_process’: flowtop.c:417:45: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] flowtop.c: In function ‘presenter_screen_update’: flowtop.c:937:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] flowtop.c:938:17: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-07-14flowtop: Mark unused parameters with __maybe_unusedTobias Klauser1-2/+2
In order to avoid compiler warnings when compiling with -W/-Wunused-parameter, mark unused function parameters with __maybe_unused. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-07-13misc: fix multiple NULL pointer sparse warningsDaniel Borkmann1-1/+1
Those are fixes for the following warnings: pcap_mm.c:119:29: warning: Using plain integer as NULL pointer pcap_mm.c:141:29: warning: Using plain integer as NULL pointer ring.c:24:31: warning: Using plain integer as NULL pointer flowtop.c:1114:22: warning: Using plain integer as NULL pointer ifpps.c:1133:29: warning: Using plain integer as NULL pointer Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-09all: show git id in --version informationDaniel Borkmann1-4/+5
In order to be able to better track regressions or to give support, let us track the Git id as well in version information. This makes the ``--version'' switch actually useful. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-08conntrack: consolidate all conntrack header includes into conntrack.hDaniel Borkmann1-4/+1
Consolidate all conntrack header includes into conntrack.h as this is more clean. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-24ifpps, flowtop: Move ncurses init and end to common moduleTobias Klauser1-21/+3
ncurses (de-)initialization is duplicated across flowtop and ifpps, so move it to an own module and use it from both tools. 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>
2013-06-12flowtop: 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>
2013-06-04xutils: eliminate xutils, move rest to epoll2Daniel Borkmann1-1/+0
Finally eliminate xutils.{c,h} and move the rest to epoll2. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04sig: add signal handling functionsDaniel Borkmann1-0/+1
Add an extra file for signal handling functions. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xio: rename xio to ioops and reduce its includesDaniel Borkmann1-1/+1
Rename xio to ioops (io-ops) and boil its include files down to a minimum. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xio: add ioexact operationsDaniel Borkmann1-3/+1
Break this out so that we only need to have sigint non-static where it is really needed. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xutils: break out string handling and lockingDaniel Borkmann1-0/+1
Break out all string handling functions and lockme stuff in order to further eliminate the big code blob in xutils, so that it can be easier maintained. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
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>
2013-05-15man: 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>
2013-05-12flowtop: Use size of destination buffer in memcpyTobias Klauser1-1/+1
The coverity scanner found the macro used as argument to sizeof suspicious. Use sizeof the destination buffer instead. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-03-19flowtop: Omit return value in flow_entry_get_sain{4,6}_obj()Tobias Klauser1-10/+6
The return value is never used by the callers, so we don't need to return anything. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-03-16flowtop: rcu: omit rcu_assign_pointerDaniel Borkmann1-4/+3
If the new pointer is NULL anyway, this results in a constant expression during compile time (NULL != NULL) where a barrier is left out. Thus, it will have no different effect using rcu_assign_pointer() than assigning it directly. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-16flowtop: close dir handle first before returning backDaniel Borkmann1-0/+1
Coverty detected that the variable "dir" going out of scope leaks the storage it points to. Thus close the handle first! Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+1208
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>
