2019-10-17EDAC/ghes: Fix Use after free in ghes_edac remove pathJames Morse1-0/+4
ghes_edac models a single logical memory controller, and uses a global ghes_init variable to ensure only the first ghes_edac_register() will do anything. ghes_edac is registered the first time a GHES entry in the HEST is probed. There may be multiple entries, so subsequent attempts to register ghes_edac are silently ignored as the work has already been done. When a GHES entry is unregistered, it calls ghes_edac_unregister(), which free()s the memory behind the global variables in ghes_edac. But there may be multiple GHES entries, the next call to ghes_edac_unregister() will dereference the free()d memory, and attempt to free it a second time. This may also be triggered on a platform with one GHES entry, if the driver is unbound/re-bound and unbound. The re-bind step will do nothing because of ghes_init, the second unbind will then do the same work as the first. Doing the unregister work on the first call is unsafe, as another CPU may be processing a notification in ghes_edac_report_mem_error(), using the memory we are about to free. ghes_init is already half of the reference counting. We only need to do the register work for the first call, and the unregister work for the last. Add the unregister check. This means we no longer free ghes_edac's memory while there are GHES entries that may receive a notification. This was detected by KASAN and DEBUG_TEST_DRIVER_REMOVE.

2019-08-23EDAC/amd64: Decode syndrome before translating addressYazen Ghannam1-7/+7
AMD Family 17h systems currently require address translation in order to report the system address of a DRAM ECC error. This is currently done before decoding the syndrome information. The syndrome information does not depend on the address translation, so the proper EDAC csrow/channel reporting can function without the address. However, the syndrome information will not be decoded if the address translation fails. Decode the syndrome information before doing the address translation. The syndrome information is architecturally defined in MCA_SYND and can be considered robust. The address translation is system-specific and may fail on newer systems without proper updates to the translation algorithm.

2019-08-23EDAC/amd64: Find Chip Select memory size using Address MaskYazen Ghannam1-44/+70
Chip Select memory size reporting on AMD Family 17h was recently fixed in order to account for interleaving. However, the current method is not robust. The Chip Select Address Mask can be used to find the memory size. There are a couple of cases. 1) For single-rank and dual-rank non-interleaved, use the address mask plus 1 as the size. 2) For dual-rank interleaved, do #1 but "de-interleave" the address mask first. Always "de-interleave" the address mask in order to simplify the code flow. Bit mask manipulation is necessary to check for interleaving, so just go ahead and do the de-interleaving. In the non-interleaved case, the original and de-interleaved address masks will be the same. To de-interleave the mask, count the number of zero bits in the middle of the mask and swap them with the most significant bits. For example, Original=0xFFFF9FE, De-interleaved=0x3FFFFFE Signed-off-by: Yazen Ghannam <yazen.ghannam@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: "linux-edac@vger.kernel.org" <linux-edac@vger.kernel.org> Cc: James Morse <james.morse@arm.com> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Cc: Tony Luck <tony.luck@intel.com> Link: https://lkml.kernel.org/r/20190821235938.118710-5-Yazen.Ghannam@amd.com

The struct chip_select array that's used for saving chip select bases and masks is fixed at length of two. There should be one struct chip_select for each controller, so this array should be increased to support systems that may have more than two controllers. Increase the size of the struct chip_select array to eight, which is the largest number of controllers per die currently supported on AMD systems. Fix number of DIMMs and Chip Select bases/masks on Family17h, because AMD Family 17h systems support 2 DIMMs, 4 CS bases, and 2 CS masks per channel. Also, carve out the Family 17h+ reading of the bases/masks into a separate function. This effectively reverts the original bases/masks reading code to before Family 17h support was added.

Commit 9da21b1509d8 ("EDAC: Poll timeout cannot be zero, p2") assumes edac_mc_poll_msec to be unsigned long, but the type of the variable still remained as int. Setting edac_mc_poll_msec can trigger out-of-bounds write.
