However, this would cause a memcpy() from a NULL pointer, in tlv_put(). Allow passing NULL and len = 0 for cases like the above: If val is NULL, use memset(0) instead of memcpy(). If len is zero, do not copy nor memset anything. Hence make tlv_put() behave in a well-defined and valid way for any and all input args; no negative fallout is possible from this patch. Add proper API doc comment. Fixes a sanitizer build failure in gsup_test: ../../../../src/libosmocore/include/osmocom/gsm/tlv.h:99:2: runtime error: null pointer passed as argument 2, which is declared to never be null Change-Id: I13dce9cd1228817890d3e81edeeb660c893c1d64 http://cgit.osmocom.org/libosmocore/commit/?id=167b3bcd7bcbc2f0d228b55068b7… commit 167b3bcd7bcbc2f0d228b55068b71a2f11699bd8 Author: Neels Hofmeyr <neels(a)hofmeyr.de> Date: Thu Nov 16 22:31:57 2017 +0100 bssgp_fc_test: fix sanitizer build: free fc struct when done Change-Id: I0ef95ee8185a4789f0732b9420243dda5104d181 http://cgit.osmocom.org/libosmocore/commit/?id=51bdbc4b9a2d27755d2ecd0eaabd… commit 51bdbc4b9a2d27755d2ecd0eaabdd65e8d1ca36d Author: Neels Hofmeyr <neels(a)hofmeyr.de> Date: Thu Nov 16 22:32:36 2017 +0100 gprs_bssgp: bssgp_fc_in(): fix mem leak on queue overflow All successful and all error code paths of bssgp_fc_in() free the msgb, except the code path calling fc_enqueue() when the msg is dropped (due to queue being full, or failure to allocate). Callers could theoretically catch the -ENOSPC return value and discard the msgb. However, in other code paths, a callback's return value is returned, which is expected to free the msgb, so such callback would have to never return -ENOSPC when it freed the msgb. Much simpler semantics would be to free the msgb in every code path, no matter which kind of error occurred. Who is currently calling bssgp_fc_in and how do they handle the return value? - bssgp_fc_test.c ignores the return value (and hits a mem leak aka sanitizer build failure if the queue is full). - fc_timer_cb() ignores the return value. - bssgp_tx_dl_ud() returns the bssgp_fc_in() rc. - which is returned by a cascade of functions leading up to being returned, for example, by gprs_llgmm_reset(), which is usually called with ignored return code. At this point it is already fairly clear that bssgp_fc_in() should always free the msgb, since the callers don't seem to distinguish even between error or success, let alone between -ENOSPC or other errors. bssgp_fc_test: assert that no msgbs remain unfreed after the tests. Adjust expected results. Helps to fix the sanitizer build of bssgp_fc_test by eliminating the mem leak.

To be able to do that, call msgb_talloc_ctx_init() and use its return value. A subsequent patch will fix a known mem leak and add assertions for 0b in 1 blocks remaining in the tall_msgb_context.

Make that obvious by outputting returned errors in the expected output. Cosmetic: - fc_in()'s return value is ignored, hence don't return anything. - add comment.

Allocating from the rate counter context allows cleaning up at the end of stats_test. Remove the comment concerning osmo-msc: one way to fix if the talloc becomes unexpected from this patch is to adjust the talloc expectations, another (preferred) way is to have no invalid rate counter names in osmo-msc.

If we create the msgb context and *don't* clean it up in the end, the sanitizer build fails because the context root is not cleaned up. Easiest is to actually allocate all msgb at NULL ctx, because then any msgb that aren't cleaned up properly would still linger, while we don't leave a root ctx that we need to clean up either.
