Subject: make run_tests -C proc: proc-pid-vm assertion failed.
Date: Fri, 9 Sep 2022 10:19:16 +0800 [thread overview]
Message-ID: <20220909021916.43293-1-jie2x.zhou@intel.com> (raw)
hi,
The test error is caused by g_vsyscall set failed.
Error output:
selftests: proc: proc-pid-vm
proc-pid-vm: proc-pid-vm.c:389: main: Assertion `rv == len' failed.
Aborted
g_vsyscall is set to 0.
In proc-pid-vm.c:
/*
* 0: vsyscall VMA doesn't exist vsyscall=none
* 1: vsyscall VMA is r-xp vsyscall=emulate
* 2: vsyscall VMA is --xp vsyscall=xonly
*/
static int g_vsyscall;
static const char *str_vsyscall;
static const char str_vsyscall_0[] = "";
static const char str_vsyscall_1[] =
"ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall]\n";
static const char str_vsyscall_2[] =
"ffffffffff600000-ffffffffff601000 --xp 00000000 00:00 0 [vsyscall]\n";
The /proc/%u/maps output is:
buf=100000000-100001000 r-xp 00000000 00:2d 2 /tmp/#2 (deleted)
ffffffffff600000-ffffffffff601000 --xp 00000000 00:00 0 [vsyscall]
So the g_vsyscall should be 2 according to commentary(2: vsyscall VMA is --xp).
Is it a bug?
best regards,
