build-config.h should contain configure/compile time settings that are
relevant for projects that use FreeRDP.
For example the compiled in plugin search paths.
When region_union_rect() was called with a rect that was above the region without
intersecting it, the first band was created too large. This patch fixes this and
add a unitary test.
All credits go to @nfedera that:
* found the bug;
* find a dataset to reproduce;
* code the unitary test;
* spotted a suspicious line that was the faulty one.
This patch contains:
* checks for malloc return value + treat callers;
* modified malloc() + ZeroMemory() to calloc();
* misc fixes of micro errors seen during the code audit:
** some invalid checks in gcc.c, also there were some possible
integer overflow. This is interesting because at the end the data are parsed
and freed directly, so it's a vulnerability in some kind of dead code (at least
useless);
** fixed usage of GetComputerNameExA with just one call, when 2 were used
in misc places. According to MSDN GetComputerNameA() is supposed to return
an error when called with NULL;
** there were a bug in the command line parsing of shadow;
** in freerdp_dynamic_channel_collection_add() the size of array was multiplied
by 4 instead of 2 on resize
Exposing lzcnt in crt.h might causes compiler errors (redefinition) with
recent versions of gcc (>=4.9) when winpr is included in other projects.
As lzcnt isn't part of crt according to MSDN and also shouldn't be
exported by default it was moved to intrin.h.
The related test was also moved to the top level directory of winpr.
The grid is composed of 64x64 blocks and should not be smaller
than the surface. If width or height were not a multiple of 64
the previous rounding resulted in a grid smaller than the surface.
1)
Added missing checks for CreateEvent which also required the
following related changes:
- changed freerdp_context_new API to BOOL
- changed freerdp_peer_context_new API to BOOL
- changed pRdpClientNew callback to BOOL
- changed pContextNew callback to BOOL
- changed psPeerAccepted callback to BOOL
- changed psPeerContextNew callback to BOOL
2)
Fixed lots of missing alloc and error checks in the
changed code's neighbourhood.
3)
Check freerdp_client_codecs_prepare result to avoid segfaults
caused by using non-initialized codecs.
4)
Fixed deadlocks in x11 caused by missing xf_unlock_x11() calls
in some error handlers
5)
Some fixes in thread pool:
- DEFAULT_POOL assignment did not match TP_POOL definition
- don't free the pool pointer if it points to the static DEFAULT_POOL
- added error handling and cleanup in InitializeThreadpool
rfx_process_message_sync:
- simplified the check if the header messages got processed
rfx_process_message_tileset:
- ObjectPool_Take result was not checked
- fail if TS_RFX_TILE block type is not CBT_TILE
- CreateThreadpoolWork result was not checked
- post decoding loop code segfaulted in error case
rfx_decoder_tile_new:
- missing malloc check
rfx_message_free:
- segfault protection
rfx_write_message_tileset:
- segfault protection
