Subject: [dpdk-dev] [Bug 19] Crash on initialization if first RTE_MAX_LCORE cores are disabled
Date: Sun, 01 Apr 2018 12:24:58 +0000 [thread overview]
Message-ID: <bug-19-3@http.dpdk.org/tracker/> (raw)
https://dpdk.org/tracker/show_bug.cgi?id=19
Bug ID: 19
Summary: Crash on initialization if first RTE_MAX_LCORE cores
are disabled
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: CONFIRMED
Severity: minor
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: solal.pirelli@gmail.com
Target Milestone: ---
In eal_common_options.c, the master lcore is found by looking for the first
enabled lcore
(http://dpdk.org/browse/dpdk/tree/lib/librte_eal/common/eal_common_options.c?h=v18.02#n1213).
However, there is no check for the case where no enabled lcore is found. In the
(unlikely!) case of all first RTE_MAX_LCORE cores being disabled, the next
instruction will cause an out-of-bounds array access, probably crashing the
app.
