Issue 10714002: Microdump writer: stop using new/malloc in compromised context (Closed)
DescriptionMicrodump writer: stop using new/malloc in compromised context A recent change in the client-side microdump write (r1404) ended up introducing a call to new() to instantiate the line buffer that microdump uses to dump its lines. new/malloc is a luxury we cannot afford in a compromised context. This change switches the line buffer to be backed by the dumper page allocator, which on Linux/Android ends up requesting pages via mmap. Also, the microdump write bails out without crashing if the page allocator failed (crash during severe OOM). BUG=640 Patch Set 1 #
