scsi: bfa: no need to check return value of debugfs_create functions

2019-01-29T05:40:40Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

scsi: bfa: integer overflow in debugfs

2017-10-17T02:35:13Z

We could allocate less memory than intended because we do: bfad->regdata = kzalloc(len << 2, GFP_KERNEL); The shift can overflow leading to a crash. This is debugfs code so the impact is very small. I fixed the network version of this in March with commit 13e2d5187f6b ("bna: integer overflow bug in debugfs").

When you copy some code, you are supposed to read it. If nothing else, there's a chance to spot and fix an obvious bug instead of sharing it... X-Song: "I Got It From Agnes", by Tom Lehrer Signed-off-by: Al Viro [ Tom Lehrer? You're dating yourself, Al ] Signed-off-by: Linus Torvalds
