Subject: tests: Ignore large memory blocks when searching for keys
X-Git-Tag: hostap_2_11~42
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7f3fe956d8d0207fea09cf3b39d06d29ae20c913;p=thirdparty%2Fhostap.git

tests: Ignore large memory blocks when searching for keys

wpa_supplicant will generally never allocate a memory block of that
size. We can therefore assume that it belongs to ASAN and we need to
ignore it.
