Subject: [PATCH lttng-tools v3] Fix: syscall_table_nb_entry invalid value when no syscalls TPs are defined
Date: Tue, 21 Mar 2017 09:31:20 +0000	[thread overview]
Message-ID: <6e1e4b6e-9e73-4afa-a987-bbafd19e243d__42885.5808488608$1490089731$gmane$org@canonical.com> (raw)

>fscanf on an empty file returns directly without assigning value to
>'index' leading to assigning the value of an uninitialized variable to
>syscall_table_nb_entry. This can result in memory allocation problems
>when listing syscalls on 'lttng list --kernel --syscall'[1][2].
