Subject: [PATCH-next 0/4] RDMA: sprintf to sysfs_emit conversions
Date: Thu, 08 Oct 2020 02:36:23 +0000 [thread overview]
Message-ID: <cover.1602122879.git.joe@perches.com> (raw)
A recent commit added a sysfs_emit and sysfs_emit_at to allow various
sysfs show functions to ensure that the PAGE_SIZE buffer argument is
never overrun and always NUL terminated.
Convert the RDMA/InfiniBand subsystem to use these new functions.
The first 2 patches exclusively used coccinelle to convert uses.
The third and fourth patches were done manually.
Compiled allyesconfig and defconfig with all infiniband options selected
no warnings, but untested, no hardward
Overall object size is reduced
total size: allyesconfig x86-64
new: 8364003 1680968 131520 10176491 9b47eb (TOTALS)
old: 8365883 1681032 131520 10178435 9b4f83 (TOTALS)
total size: defconfig x86-64 with all infiniband selected
new; 1359153 131228 1910 1492291 16c543 (TOTALS)
old: 1359422 131228 1910 1492560 16c650 (TOTALS)
Joe Perches (4):
RDMA: Convert sysfs device * show functions to use sysfs_emit()
RDMA: Convert sysfs kobject * show functions to use sysfs_emit()
RDMA: manual changes for sysfs_emit and neatening
RDMA: Convert various random sprintf sysfs _show uses to sysfs_emit
