Tobias Brunner 985dcab1c2 utils: Convert string helper macros to static inline functions 2013-07-08 18:49:29 +02:00
Tobias Brunner f95205f580 integrity-checker: Use chunk_hash_static() to calculate checksums 2013-06-28 17:00:29 +02:00
Tobias Brunner ed235dbbf2 chunk: Add predictable hash function 
Since chunk_hash() is randomized its output is not predictable, that is,
it is only within the same process.

Tobias Brunner 6f15f5e632 dhcp: Require CAP_NET_BIND_SERVICE and CAP_NET_RAW to open/bind sockets 2013-06-25 17:16:32 +02:00
Tobias Brunner 1dd61bf13d socket-default: Require CAP_NET_BIND_SERVICE for ports < 1024 
Since we don't know which ports are used with socket-dynamic we can't
demand the capability there, but it might still be required.
 2013-06-25 17:16:32 +02:00
Tobias Brunner 41b8546ac0 capabilities: Only plugins that require CAP_NET_ADMIN demand it 
The daemon as such does not require this capability.

Tobias Brunner 0d2ad63fe2 printf-hook: Avoid double-free when freeing Vstr config 
Thread-specific objects get freed when the thread value object is
destroyed (wasn't the case earlier, i.e. before 2b19dd35), which
may cause the second call to vstr_free_conf() to fail in an assert
in Vstr (depending on how it was built).

Martin Willi 092550b03a leak-detective: (re-)whitelist some OpenSSL functions 
Some static allocations in plugins won't get freed, because in the test case
process the plugins are not destroyed. If a plugin would clean up allocations
done while just using the plugin, these show up as leak in the child process,
letting tests fail.

Martin Willi ad58246f53 backtrace: use backtrace_symbols() only if we have backtrace() and dladdr() fails 2013-06-19 16:09:31 +02:00
Tobias Brunner 4d04e2c63b utils: Remove volatile qualifier from refcount_t typedef 
It's not really required anymore (if it ever was) and may cause compiler
warnings when using the non atomic versions of ref_get/ref_put.
 2013-06-19 09:28:30 +02:00
Martin Willi 3160b92adb utils: ref_get() returns the new value of the reference counter 
This allows us to use ref_get() for getting unique values.

Tobias Brunner f5f7053bcd leak-detective: Resolve hooked functions during initialization 
If uses of dlopen(), e.g. when loading plugins, produce errors an error
string could get allocated dynamically.  At this point realloc() might not
yet be resolved and when dlsym() is later called by leak detective to do
so the error string might get freed while leak detective is disabled and
real_free() will be called with a pointer into one of leak detective's
memory blocks instead of a pointer to the block itself, causing a SIGSEGV.

Tobias Brunner b1abf22bd0 Fail DN parsing if OID is unterminated 
This is the case if the last OID is not followed by a = or if the string
starts with a =.

Tobias Brunner 78c37de15a Use chunk_from_str in identification_from_string 
We always have a non-empty string in those cases as "" is now handled
as ID_ANY.
 2013-06-11 11:03:12 +02:00
Tobias Brunner c1be5d66cd Use local variable in chunk_from_str() 
This allows using strdup() or other string functions as argument
without calling them twice.

Tobias Brunner 819c02dbc6 timeval_add_ms() fixed 
1000000us are exactly 1s so.

Tobias Brunner bed4bc1327 Randomly allocate chunk_hash() key during first use 
This avoids hash flooding attacks.
 2013-06-11 11:03:11 +02:00
Tobias Brunner d1953fe403 Replace chunk_hash() with output from chunk_mac() 
The quality is way better, the calculation is a bit slower though.

The key is statically initialized to zero, which will be changed later
to prevent hash flooding.

Martin Willi 69333acee0 settings: Add a set_default_str() to set a different default for a key 
The value is set only if it is not configured in strongswan.conf or has
not been set() otherwise.

Martin Willi 3117824f55 leak-detective: align allocations on both 32 and 64-bit systems to 32 bytes 2013-05-06 15:15:24 +02:00
Martin Willi 7e3f6299d5 leak-detective: call tzset() explicitly before enabling leak detective 
tzset() is hard to whitelist on some systems, as there is no symbol involved.
Call tzset() explicitly before initialization to avoid false positives.
 2013-05-06 15:15:24 +02:00
Martin Willi 17211b6b9a leak-detective: override malloc functions instead of using deprecated hooks 
malloc hooks have become deprecated, and their use has always been problematic,
especially in multi-threaded applications. Replace the functionality by
overriding all malloc functions and query the system allocator functions
using dlsym() with RTLD_NEXT.
