* xcms: Fix memory leaks on LINEAR_RGB_InitSCCData error path.Ander Conselvan de Oliveira2016-10-191-3/+3
| | | | | | | | | | | pScreenData is replaced when building per visual intensity tables. If malloc failed the old value of pScreenData (stored also in pScreenDefaultData) was being leaked. Also, property_return wasn't free'd in that case.

| | | | | | | | | | | | | property_return was free'd before and in the case the conditional is true, the call to XcmsGetProperty failed which means that property_return wasn't set so there is no need to free it again.

| | | | | | | | | | | | The rest of the code uses goto's to free memory allocated later and prevent memory leaks, but there were several paths were property_return was free'd just before a goto.

* LINEAR_RGB_InitSCCData: When malloc fails, don't try to free unallocated bitsAlan Coopersmith2016-10-191-1/+1
| | | | | | | | | | | | | | | | | | One of the malloc failure checks had a goto to the wrong spot in the list of cleanup free() calls to unwind at the end, and was freeing bits that hadn't been initialized/allocated yet, since they would be stored in the struct that just failed to be allocated. Error: Null pointer dereference (CWE 476) Read from pointer that could be constant 'NULL' at line 805 of /export/alanc/X.Org/sx86/lib/libX11/nx-X11/lib/X11/LRGB.c in function 'LINEAR_RGB_InitSCCData'. Pointer checked against constant 'NULL' at line 754 but does not protect the dereference. [ This bug was found by the Parfait bug checking tool.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-2/+2
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
