Don't use pcre for the high level rule parsing, instead
using a tokenizing parser for breaking out the rule
into keywords and options.
Much faster, especially on older CPUs. Should also allow
us to provide better context where a rule parse error
occurs.
Converting the NTP parser to the new registration method is a simple,
3-steps process:
- change the extern functions to use generic input parameters (functions
in all parsers must share common types to be generic) and cast them
- declare the Parser structure
- remove the C code and call the registration function
Add Rust support for the common interface to declare and register all
parsers.
Add a common structure definition to contain all required elements
required for registering a parser, similar to the C interface.
This also reduces the risk of incorrectly registering a parser: the
compiler prevents omitting required functions from the structure, and
functions (even if external) are type-checked. Optional functions are
explicitly marked.
Add a common structure definition to contain all required elements
required for registering a parser.
This also reduces the risk of incorrectly registering a parser: the
compiler will type-check functions.
The registration function allows factorization of the code. It can be
used to register parsers, but is not mandatory.
If extra registration code (for functions not in the structure)
it is still possible by calling the C functions after the registration.
Add StringToAppProto to map a protocol name to a AppProto.
Exposing this function is required to let parsers discover their
AppProto identifier constant dynamically.
For example, a parser can request this value, and use it for
registration without knowing the value.
pfring.h brings a different version of likely/unlikely that gives
warnings. So make sure we include our own before.
Make sure pfring.h isn't included globally due to apparent redefinition
of pthread_rwlock_t.
This patch adds support for hw bypass by enabling flow offload in the network
card (when supported) and implementing the BypassPacketsFlow callback.
Hw bypass support is disabled by default, and can be enabled by setting
"bypass: yes" in the pfring interface configuration section in suricata.yaml.
Netflow entry collects the minimum and maximum
time to live during the life of the incoming flow.
This adds those field to a netflow event.

Fixes issue with events being dropped since socket was non-blocking for
offline run modes.
Add a method for determining offline from run mode. Make sure SCInstance
offline is set correctly. Use current run mode to set socket flags.
SCLogMapLogLevelToSyslogLevel(): treat SC_LOG_PERF messages as LOG_DEBUG
Previously, when logging to syslog, perf events had a default EMERG priority,
which could be a bit confusing.
An empty value for coredump.max-dump in the config-file leads to a segfault because of a NULL-pointer dereference in CoredumpLoadConfig().
Here is a configuration example:
coredump.max-dump: []
This lets suricata crash with a segfault:

Bug #2276
If there are empty values in the config-file where integer values are expected, strtoimax in the ConfGetInt-function will segfault because of NULL-pointer dereference.
Here is a configuration example:
pcre.match-limit: []
This will let suricata crash with a segfault.
