Victor Julien	8fa5a2c025	Split applayer and raw stream reassembly ... Split stream reassembly in 2 parts: a part that sends ack'd data to the app layer parsers as soon as it's available, and another part that queues up data into larger chunks for raw inspection.	14 years ago

Eric Leblond	9c2bdc6d0c	Main loop: increase timer. ... Timer in the main loop was of 100 usec. This patch increases it to 10 ms which should be a reasonnable delay to declare some threads dead. Signed-off-by: Eric Leblond <eric@regit.org>	14 years ago
Eric Leblond	89558ab9a4	RFC: modify error treatment in PacketCopyData ... Hello Victor This patch modifies error treatment following our discussion on IRC. It tries to follow the error treatment guideline I've been able to read in the different files. I will merge this patch in the original commit if the error treatment seems ok for you. BR, Eric	14 years ago
Eric Leblond	49adc264bc	Don't print message after SCMalloc failure. ... This patch generated via coccinelle is getting rid of logging message after a SCMalloc failure. They were useless as SCMalloc already displays a message.	14 years ago
Eric Leblond	67b95c8c4d	Auto discovery of default packet size ... If default-packet-size is not set, it is possible in some case to guess a correct value. If PCAP or PF_RING are used we are linked to a "physical" interface. Thus, it is possible to get information about the link MTU and hardware header size. This give us the ability to auto discover a decent default-packet-size. If suricata is running under a different running-mode, it will default to 1514.	14 years ago
Eric Leblond	3eada85ff8	Add interface setting discovery via ioctl ... This patch adds support for MTU discovery of link following idea of go.ph1g. It also adds some function to give a approximation of link header length.	14 years ago
Eric Leblond	1db4aadd16	Supress usage of Packet declaration in tests. ... For convenience, a massive usage of 'Packet p;' declaration has been done in the tests function. Although this was completely legal, this is not possible anymore because of the new Packet allocation structure. This massive patch modifies all suricata files to use a SCMalloc allocated pointer to Packet instead. This patch has been done using coccinelle (http://coccinelle.lip6.fr) which is a semantic patching tool. This ensures that things like call to SCFree() should have not been forget because the semantic patch explicitly forces the call to SCFree(p) before each return. With this patch all unittests are running fine with a small and a big default packet size.	14 years ago
Eric Leblond	156b202597	Fix decode part of source-nfq	14 years ago
Eric Leblond	dd038c1906	Modify files to avoid direct pckt payload access ... This patch implements the needed modification of payload access in a Packet structure to support the abstraction introduced by the extended data system.	14 years ago
Eric Leblond	e802e1ed16	Modify Packet structure and prepare accessor. ... This patch modifies decode.c and decode.h to avoid the usage by default of a bigger than 65535 bytes array in Packet structure. The idea is that the packet are mainly under 1514 bytes size and a bigger size must be supported but should not be the default. If the packet length is bigger than DFLT_PACKET_SIZE then the data are stored in a dynamically allocated part of the memory. To ease the modification of the rest of the code, functions to access and set the payload/length in a Packet have been introduced. The default packet size can be set at runtime via the default-packet-size configuration variable.	14 years ago
Eric Leblond	8471626916	Fix error message and adds information to config ... This patch fixes a typo in an error message and add some information to the checksum verification option.	14 years ago
