Patch "bnx2x: Improve reliability in case of nested PCI errors" has been added to the 4.14-stable tree

Piccoli" <gpiccoli(a)linux.vnet.ibm.com> [ Upstream commit f7084059a9cb9e56a186e1677b1dcffd76c2cd24 ] While in recovery process of PCI error (called EEH on PowerPC arch), another PCI transaction could be corrupted causing a situation of nested PCI errors. Also, this scenario could be reproduced with error injection mechanisms (for debug purposes). We observe that in case of nested PCI errors, bnx2x might attempt to initialize its shmem and cause a kernel crash due to bad addresses read from MCP. Multiple different stack traces were observed depending on the point the second PCI error happens. This patch avoids the crashes by: * failing PCI recovery in case of nested errors (since multiple PCI errors in a row are not expected to lead to a functional adapter anyway), and by, * preventing access to adapter FW when MCP is failed (we mark it as failed when shmem cannot get initialized properly).

Steps to reproduce: - start AVB TX stream (Using aplay via MSE), - disconnect+reconnect the eth cable, - after a reconnection the eth connection goes iteratively up/down without user interaction, - this may heal after some seconds or even stay for minutes. As the documentation specifies, the "renesas,no-ether-link" option should be used when a board does not provide a proper AVB_LINK signal. There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS and ULCB starter kits since the AVB_LINK is correctly handled by HW. Choosing to keep or remove the "renesas,no-ether-link" option will have impact on the code flow in the following ways: - keeping this option enabled may lead to unexpected behavior since the RX & TX are enabled/disabled directly from adjust_link function without any HW interrogation, - removing this option, the RX & TX will only be enabled/disabled after HW interrogation. The HW check is made through the LMON pin in PSR register which specifies AVB_LINK signal value (0 - at low level; 1 - at high level). In conclusion, the present change is also a safety improvement because it removes the "renesas,no-ether-link" option leading to a proper way of detecting the link state based on HW interrogation and not on software heuristic.

Patch "mtd: nand: gpmi: Fix failure when a erased page has a bitflip at BBM" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled mtd: nand: gpmi: Fix failure when a erased page has a bitflip at BBM to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: mtd-nand-gpmi-fix-failure-when-a-erased-page-has-a-bitflip-at-bbm.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Wed Feb 28 16:19:30 CET 2018 From: Sascha Hauer <s.hauer(a)pengutronix.de> Date: Tue, 5 Dec 2017 11:51:40 +0100 Subject: mtd: nand: gpmi: Fix failure when a erased page has a bitflip at BBM From: Sascha Hauer <s.hauer(a)pengutronix.de> [ Upstream commit fdf2e821052958a114618a95ab18a300d0b080cb ] When erased subpages are read then the BCH decoder returns STATUS_ERASED if they are all empty, or STATUS_UNCORRECTABLE if there are bitflips. When there are bitflips, we have to set these bits again to show the upper layers a completely erased page. When a bitflip happens in the exact byte where the bad block marker is, then this byte is swapped with another byte in block_mark_swapping(). The correction code then detects a bitflip in another subpage and no longer corrects the bitflip where it really happens. Correct this behaviour by calling block_mark_swapping() after the bitflips have been corrected. In our case UBIFS failed with this bug because it expects erased pages to be really empty: UBIFS error (pid 187): ubifs_scan: corrupt empty space at LEB 36:118735 UBIFS error (pid 187): ubifs_scanned_corruption: corruption at LEB 36:118735 UBIFS error (pid 187): ubifs_scanned_corruption: first 8192 bytes from LEB 36:118735 UBIFS error (pid 187): ubifs_scan: LEB 36 scanning failed UBIFS error (pid 187): do_commit: commit failed, error -117 Signed-off-by: Sascha Hauer <s.hauer(a)pengutronix.de> Reviewed-by: Richard Weinberger <richard(a)nod.at> Acked-by: Boris Brezillon <boris.brezillon(a)free-electrons.com> Signed-off-by: Richard Weinberger <richard(a)nod.at> Signed-off-by: Sasha Levin <alexander.levin(a)microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/mtd/nand/gpmi-nand/gpmi-nand.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) --- a/drivers/mtd/nand/gpmi-nand/gpmi-nand.c +++ b/drivers/mtd/nand/gpmi-nand/gpmi-nand.c @@ -1029,9 +1029,6 @@ static int gpmi_ecc_read_page(struct mtd return ret; } - /* handle the block mark swapping */ - block_mark_swapping(this, payload_virt, auxiliary_virt); - /* Loop over status bytes, accumulating ECC status. */ status = auxiliary_virt + nfc_geo->auxiliary_status_offset; @@ -1047,6 +1044,9 @@ static int gpmi_ecc_read_page(struct mtd max_bitflips = max_t(unsigned int, max_bitflips, *status); } + /* handle the block mark swapping */ + block_mark_swapping(this, buf, auxiliary_virt); + if (oob_required) { /* * It's time to deliver the OOB bytes.
