Petr Štetiar cc344f1513 ubus: backport fixes for UAF and other issues ... Backporting following fixes: a72457b61df0 libubus: increase stack depth for processing obj msgs ef038488edc3 libubus: process pending messages in data handler if stack depth is 0 2099bb3ad997 libubus: use list_empty/list_first_entry in ubus_process_pending_msg where at least commit 2099bb3ad997 ("libubus: use list_empty/list_first_entry in ubus_process_pending_msg") fixes UAF issue I've introduced in commit c5f2053dfcfd ("workaround possibly false positive uses of memory after it is freed") while fixing another false positive UAF reported[1] by clang's static analyzer. Those fixes are being used in master/21.02 for about 6 months, so should be tested enough and considered for backporting. I've runtested those fixes on mvebu/turris-omnia and ipq40xx/glinet-b1300 devices. 1. https://openwrt.gitlab.io/-/project/ubus/-/jobs/2096090992/artifacts/build/scan/2022-02-15-150310-70-1/index.html Signed-off-by: Petr Štetiar <ynezz@true.cz>		2022-02-21 07:41:05 +01:00
