* avfilter/af_amix: Fix double-free of AVFilterChannelLayouts on errorAndreas Rheinhardt2020-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | The query_formats function of the amix filter tries to allocate a list of channel layouts which are attached to more permanent objects (an AVFilter's links) for storage afterwards on success. If attaching a list to a link succeeds, the link becomes one of the common owners of the list. Yet if a list has been successfully attached to links (or if there were no links to attach it to in which case ff_set_common_channel_layouts() already frees the list) and an error happens lateron, the list was manually freed, which is wrong, because the list has either already been freed or it is owned by its links in which case these links' pointers to their list will become dangling and there will be double-frees/uses-after-free when these links are cleaned up automatically. This commit fixes this by removing the custom freeing code; this is made possible by using the list in ff_set_common_channel_layouts() directly after its allocation (without anything that can fail in between). Notice that ff_set_common_channel_layouts() is buggy itself which can lead to double-frees on error. This is not fixed in this commit.

* avfilter/af_amix: Don't needlessly reallocate tableAndreas Rheinhardt2020-08-23
| | | | | | | | | | | Replace using ff_add_format() repeatedly by a single call to ff_make_format_list(). (Right now this also fixes a memleak: If the first ff_add_format() succeeds and a subsequent call fails, the list leaks.)

* lavfi/af_amix: fix memory leakGanesh Ajjanagadde2015-12-09
| | | | | | | | | | | | | | | | | Recent commits 6aaac24d72a7da631173209841a3944fcb4a3309 and 3835554bf8ed78539a3492c239f979c0ab03a15f made progress towards cleaning up usage of the formats API, and in particular fixed possible NULL pointer dereferences. This commit addresses the issue of possible resource leaks when some intermediate call fails. Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation of malloc/realloc failures. Fixes: CID 1250334. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

* avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde2015-10-14
| | | | | | | | | | | | | | | | | | Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.
