Add per packet profiling. Per packet profiling uses tick based accounting. It has 2 outputs, a summary and a csv file that contains per packet stats. Stats per packet include: 1) total ticks spent 2) ticks spent per individual thread module 3) "threading overhead" which is simply calculated by subtracting (2) of (1). A number of changes were made to integrate the new code in a clean way: a number of generic enums are now placed in tm-threads-common.h so we can include them from any part of the engine. Code depends on --enable-profiling just like the rule profiling code. New yaml parameters: profiling: # packet profiling packets: # Profiling can be disabled here, but it will still have a # performance impact if compiled in. enabled: yes filename: packet_stats.log append: yes # per packet csv output csv: # Output can be disabled here, but it will still have a # performance impact if compiled in. enabled: no filename: packet_stats.csv Example output of summary stats: IP ver Proto cnt min max avg ------ ----- ------ ------ ---------- ------- IPv4 6 19436 11448 5404365 32993 IPv4 256 4 11511 49968 30575 Per Thread module stats: Thread Module IP ver Proto cnt min max avg ------------------------ ------ ----- ------ ------ ---------- ------- TMM_DECODEPCAPFILE IPv4 6 19434 1242 47889 1770 TMM_DETECT IPv4 6 19436 1107 137241 1504 TMM_ALERTFASTLOG IPv4 6 19436 90 1323 155 TMM_ALERTUNIFIED2ALERT IPv4 6 19436 108 1359 138 TMM_ALERTDEBUGLOG IPv4 6 19436 90 1134 154 TMM_LOGHTTPLOG IPv4 6 19436 414 5392089 7944 TMM_STREAMTCP IPv4 6 19434 828 1299159 19438 The proto 256 is a counter for handling of pseudo/tunnel packets.

Add option on Tile-Gx for logging for fast.log alerts over PCIe When running on a TILEncore-Gx PCIe card, setting the filetype of fast.log to pcie, will open a connection over PCIe to a host application caleld tile-pcie-logd, that receives the alert strings and writes them to a file on the host. The file name to open is also passed over the PCIe link. This allows running Suricata on the TILEncore-Gx PCIe card, but have the alerts logged to the host system's file system efficiently. The PCIe API that is used is the Tilera Packet Queue (PQ) API which can access PCIe from User Space, thus avoiding system calls. Created util-logopenfile-tile.c and util-logopen-tile.h for the TILE specific PCIe logging functionality. Using Write() and Close() function pointers in LogFileCtx, which default to standard write and close for files and sockets, but are changed to PCIe write and close functions when a PCIe channel is openned for logging. Moved Logging contex out of tm-modules.h into util-logopenfile.h, where it makes more sense. This required including util-logopenfile.h into a couple of alert-*.c files, which previously were getting the definitions from tm-modules.h. The source and Makefile for tile-pcie-logd are added in contrib/tile-pcie-logd. By default, the file name for fast.log specified in suricata.yaml is used as the filename on the host. An optional argument to tile-pcie-logd, --prefix=, can be added to prepend the supplied file path. For example, is the file in suricata.yaml is specified as "/var/log/fast.log" and --prefix="/tmp", then the file will be written to "/tmp/var/log/fast.log". Check for TILERA_ROOT environment variable before building tile_pcie_logd Building tile_pcie_logd on x86 requires the Tilera MDE for its PCIe libraries and API header files. Configure now checs for TILERA_ROOT before enabling builing tile_pcie_logd in contrib/tile_pcie_logd
