[SCSI] aacraid: fix security weakness

2008-01-06T02:19:00+00:00

Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them. Signed-off-by: Alan Cox Acked-by: Mark Salyzyn Signed-off-by: James Bottomley Signed-off-by: Adrian Bunk

aacraid: fix security hole (CVE-2007-4308)

2007-11-02T02:41:27+00:00

On the SCSI layer ioctl path there is no implicit permissions check for ioctls (and indeed other drivers implement unprivileged ioctls). aacraid however allows all sorts of very admin only things to be done so should check. Signed-off-by: Alan Cox Acked-by: Mark Salyzyn Signed-off-by: Adrian Bunk

[SCSI] QLOGICPTI: Do not unmap DMA unless we actually mapped something.

2007-04-19T23:31:17+00:00

We only map DMA when cmd->request_bufflen is non-zero for non-sg buffers, we thus should make the same check when unmapping. Based upon a report from Pasi Pirhonen. Signed-off-by: David S. Miller Signed-off-by: Adrian Bunk

[SCSI] arcmsr: fix up sysfs values

2007-01-30T20:23:00+00:00

The sysfs files in arcmsr are non-standard in that they aren't simple filename value pairs, the values actually contain preceeding text which would have to be parsed. The idea of sysfs files is that the file name is the description and the contents is a simple value. Fix up arcmsr to conform to this standard.

[SCSI] areca sysfs fix

2007-01-30T20:22:58+00:00

Remove sysfs_remove_bin_file() return-value checking from the areca driver. There's nothing a driver can do if sysfs file removal fails, so we'll soon be changing sysfs_remove_bin_file() to internally print a diagnostic and to return void. Signed-off-by: Andrew Morton Signed-off-by: Adrian Bunk
