scsi: aacraid: Use correct channel number for raw srb

2017-02-22T23:41:41+00:00

The channel being used for raw srb commands is retrieved from the utility sent fibs and is converted into physical channel id. The driver does not need to to do this since the management utility sends the correct channel id in the first place and in addition the driver sets inaccurate information in the cmd sent to the firmware and gets an invalid response. Fixed by using channel id from srb command.

aacraid: Check size values after double-fetch from user

2016-08-09T01:34:02+00:00

In aacraid's ioctl_send_fib() we do two fetches from userspace, one the get the fib header's size and one for the fib itself. Later we use the size field from the second fetch to further process the fib. If for some reason the size from the second fetch is different than from the first fix, we may encounter an out-of- bounds access in aac_fib_send(). We also check the sender size to insure it is not out of bounds. This was reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was assigned CVE-2016-6480.

aacraid: Fix AIF triggered IOP_RESET

2016-02-24T02:27:02+00:00

while driver removal is in progress or PCI shutdown is invoked, driver kills AIF aacraid thread, but IOCTL requests from the management tools re-start AIF thread leading to IOP_RESET. Fixed by setting adapter_shutdown flag when PCI shutdown is invoked.

aacraid: Created new mutex for ioctl path

2016-02-24T02:27:02+00:00

aac_mutex was used to create protect the ioctl path for only the compat path, it would be make more sense to place mutex in aac_do_ioctl, which is the main ioctl function call that handles all ioctl commands. Created new mutex ioctl_mutex in struct aac_dev to protect switch case in aac_do_ioctl and removed aac_mutex from aac_cfg_ioctl and aac_compat_do_ioctl Signed-off-by: Raghava Aditya Renukunta Reviewed-by: Tomas Henzl Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
