to each detector's "free" function.

Victor Julien 14896365ef detect: remove Threadvars argument from API calls 
Remove it as it's (almost) never used. If it is really needed it can
be accessed through DetectEngineThreadCtx::tv as well.

Victor Julien ab1200fbd7 compiler: more strict compiler warnings 
Set flags by default:

    -Wmissing-prototypes
    -Wmissing-declarations
    -Wstrict-prototypes
    -Wwrite-strings
    -Wcast-align
    -Wbad-function-cast
    -Wformat-security
    -Wno-format-nonliteral
    -Wmissing-format-attribute
    -funsigned-char

Fix minor compiler warnings for these new flags on gcc and clang.

Ken Steele 923a77e952 Change Match() function to take const SigMatchCtx* 
The Match functions don't need a pointer to the SigMatch object, just the
context pointer contained inside, so pass the Context to the Match function
rather than the SigMatch object. This allows for further optimization.

Change SigMatch->ctx to have type SigMatchCtx* rather than void* for better
type checking. This requires adding type casts when using or assigning it.

The SigMatch contex should not be changed by the Match() funciton, so pass it
as a const SigMatchCtx*.

Victor Julien c583c9e205 tag: fix session seconds tracking 
Fix bug #995. Tag time setting was initialized using "usec" field
instead of "sec" field. This led to immediate timing out of tag.

Added proper matching unittests for all tagging types.

Bug #995.

Eric Leblond e176be6fcc Use unlikely for error treatment. 
When handling error case on SCMallog, SCCalloc or SCStrdup
we are in an unlikely case. This patch adds the unlikely()
expression to indicate this to gcc.

This patch has been obtained via coccinelle. The transformation
is the following:

@istested@
identifier x;
statement S1;
identifier func =~ "(SCMalloc|SCStrdup|SCCalloc)";
@@

x = func(...)
... when != x
- if (x == NULL) S1
+ if (unlikely(x == NULL)) S1

Eric Leblond 0227a87fcb cleaning: fix warning when building with clang. 
clang was issuing some warnings related to unused return in function.
This patch adds some needed error treatment and ignore the rest of the
warnings by adding a cast to void.

Victor Julien e581ec7dff Fix 2 compilation issues. 14 years ago
Victor Julien a05df345de Introduce host table, make tag use it 
Add a host table similar to the flow table. A hash using fine grained
locking. Flow manager for now takes care of book keeping / garbage
collecting.

Tag subsystem now uses this for host based tagging instead of the
global tag hash table. Because the latter used a global lock and the
new code uses very fine grained locking this patch should improve
scalability.

Anoop Saldanha ff38d42bf1 code cleanup - replace SigMatchAppendTag with SigMatchAppendSMToList 14 years ago
Victor Julien 262a7300d7 flow: shrink Flow datatype 
Introduce a separate FlowAddress structure for holding the ipv4 or ipv6 address
that doesn't have the family in it like the Address structure. Instead, the
family is stored in the flow as a flag: FLOW_IPV4 and FLOW_IPV6.

Add macro's to check the family, copy the address, etc.

Update many unittests to reflect these changes. Introduce unittest helper
functions for creating and initializing a flow and freeing it again.

On 64 bit this shrinks the flow with 8 bytes.

- Removed TimeGet call from tag packet runtime to safe a gettimeofday
- Removed unused lock from data type
- Fixed broken first packet skip logic
- Fix broken reference counter logic
- Fix memory leak on tag expiration
- Cleaned up code

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.
