* Fix for buffer overflow defect.Artur Wojcik2009-12-101-1/+1
| | | | | | | | Array index of 'path' may be out of bounds. Array 'path' of size 256 may use index value(s) 0..284. Signed-off-by: Artur Wojcik <artur.wojcik@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* Fix for buffer overflow defect in 'link'.Artur Wojcik2009-12-101-1/+5
| | | | | | | | Potential buffer overflow of 'link' caused by user input may occur, due to non null-terminated string 'link'. Signed-off-by: Artur Wojcik <artur.wojcik@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* platform: relax rom scanning alignment for ahci platformsDan Williams2009-07-311-1/+6
| | | | | | | | | | | | | | | | The PCI-3.0 Firmware specification allows for option-roms to have 512-byte alignment rather than 2048-byte. As there does not appear to be a reliable method to detect a PCI-3.0 compliant BIOS from userspace we allow the imsm platform detection code to presume that a system modern enough to have an Intel AHCI controller does not have dangerous/legacy ISA regions in the option-ROM memory space. An environment variable to disable this behaviour, IMSM_SAFE_OROM_SCAN, is added in case this presumption is ever proven wrong.

* imsm: provide a simulated option-rom for regression testsDan Williams2009-02-231-0/+18
| | | | | | | | | | | IMSM_NO_PLATFORM turns off checks that should be tested, so provide a IMSM_TEST_OROM variable to allow testing the orom constraints in the mdadm regression suite. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* imsm: detect option-rom capabilitiesDan Williams2008-12-081-0/+178
The option-rom advertises its capabilities in a data structure located in the platform ROM region 0xc0000-0xf0000. Attempt to detect the option-rom and limit array creation to the platform's capabilities. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
