Martin Willi 95726f7617 types: Use generic type definitions to separate header file 2015-04-16 14:49:19 +02:00

Martin Willi d72817491d leak-detective: Whitelist gcrypt_plugin_create() 
gcry_check_version() does not free statically allocated resources. However,
we can't whitelist it in some versions, as it is not a resolvable symbol name.
Instead, whitelist our own plugin constructor function.

Martin Willi 0c83225883 utils: Provide aligning variants of INIT/INIT_EXTRA macros 2015-04-15 13:44:40 +02:00
Martin Willi f206bb7444 utils: Add malloc/free wrappers returning aligned data 
While we could use posix_memalign(3), that is not fully portable. Further, it
might be difficult on some platforms to properly catch it in leak-detective,
which results in invalid free()s when releasing such memory.

We instead use a simple wrapper, which allocates larger data, and saves the
padding size in the allocated header. This requires that memory is released
using a dedicated function.

To reduce the risk of invalid free() when working on corrupted data, we fill up
all the padding with the padding length, and verify it during free_align().

Martin Willi 04337fed02 apple: Redefine some additional clashing Mach types 
While they usually are not included in a normal strongSwan build, the XPC
header indirectly defines these Mach types. To build charon-xpc, which uses
both XPC and strongSwan includes, we have to redefine these types.

Martin Willi 6e4620adfb apple: Use precancelable poll() to wrap accept/recvmsg calls 
To make accept/recvmsg cancelable, we wrap them with poll. As poll itself
does not honor pending cancellations when entering the function, we use our
variant that checks for pending cancellation requests before entering poll().

Tobias Brunner eb218ff80b chunk: Fix internet checksum calculation on big-endian systems 
ntohs() might be defined as noop (#define ntohs(x) (x)) so we have
to manually shorten the negated value (gets promoted to an int).

Fixes #747.

a static allocation of compression algorithms not freed.

Martin Willi bb6be26197 utils: Add some initial build time assertion macros 
These are useful to assert constants during build time. We evaluate the
expression to 0 when valid, so we can safely use the evaluated value.

Some platforms, such as OS X, use macros for these functions. Undefine them
to avoid compiler warnings.

Martin Willi 07b57e203b windows: Include <sys/stat.h> explicitly before overloading memset()/memcpy() 
fstat() in newer MinGWs is defined as non-static inline. With our new static
inline memset()/memcpy() overloads, this raises a warning. To avoid it,
explicitly include <sys/stat.h> once before defining these overloads.

Tobias Brunner 6d4654b9f9 utils: Add wrappers for memcpy(3), memmove(3) and memset(3) 
These wrappers guarantee that calls to these functions are noops if the
number of bytes is 0, as calling them with NULL pointers is undefined
according to the C standard, even if the number of bytes is 0 (most
implementations probably ignore the pointers anyway in this case, but
lets make sure).
