[lwip-devel] [bug #21433] Calling mem_free/pbuf_free from interrupt context isn't safe

[Jonathan Larmour]

Follow-up Comment #15, bug #21433 (project lwip):

I'm slightly unsure about referring to disabling interrupts all the time
since on many embedded OSes this would actually disable tasking, which is
slightly different.

I think the opt.h comment could clarify that pbuf_free_int (and mem_free) are
functions which already exist and don't need writing. Perhaps this should also
be documented somewhere else? Wiki? 

I think the implementation could be improved by my suggestion in comment #10.
But then I'm not the one doing it, so it's up to you :-).
