Subject: [PATCH AUTOSEL 5.6 22/50] selftests/ftrace: Check the first record for kprobe_args_type.tc
Date: Thu, 7 May 2020 10:26:58 -0400 [thread overview]
Message-ID: <20200507142726.25751-22-sashal@kernel.org> (raw)
In-Reply-To: <20200507142726.25751-1-sashal@kernel.org>
From: Xiao Yang <yangx.jy@cn.fujitsu.com>
[ Upstream commit f0c0d0cf590f71b2213b29a7ded2cde3d0a1a0ba ]
It is possible to get multiple records from trace during test and then more
than 4 arguments are assigned to ARGS. This situation results in the failure
of kprobe_args_type.tc. For example:
-----------------------------------------------------------
grep testprobe trace
ftracetest-5902 [001] d... 111195.682227: testprobe: (_do_fork+0x0/0x460) arg1=334823024 arg2=334823024 arg3=0x13f4fe70 arg4=7
pmlogger-5949 [000] d... 111195.709898: testprobe: (_do_fork+0x0/0x460) arg1=345308784 arg2=345308784 arg3=0x1494fe70 arg4=7
grep testprobe trace
sed -e 's/.* arg1=\(.*\) arg2=\(.*\) arg3=\(.*\) arg4=\(.*\)/\1 \2 \3 \4/'
ARGS='334823024 334823024 0x13f4fe70 7
345308784 345308784 0x1494fe70 7'
-----------------------------------------------------------
We don't care which process calls do_fork so just check the first record to
fix the issue.
