However, only the boundary words (the first and the last) are\n> populated from the EEPROM if the write request is not word-aligned.\n> The words in the middle of the buffer remain uninitialized because\n> they are intended to be completely overwritten by the new data via\n> memcpy().\n> \n> The previous implementation had a loop that performed le16_to_cpus()\n> on the entire buffer. This resulted in endianness conversion being\n> performed on uninitialized memory for all interior words.\n> \n> Fix this by converting the endianness only for the boundary words\n> immediately after they are successfully read from the EEPROM.\n> \n> Found by Linux Verification Center (linuxtesting.org) with SVACE.\n> \n> Co-developed-by: Iskhakov Daniil \n> Signed-off-by: Iskhakov Daniil \n> Signed-off-by: Agalakov Daniil \n> ---\n> v2:\n> - Split from the original bugfix series and targeted at 'net-text'.\n> - Removed the Fixes: tag; limiting the conversion scope is an\n> improvement to avoid unnecessary processing of uninitialized\n> memory.\n> - Improved commit description for clarity.\n> - Note on e1000e: this driver already contains the necessary return\n> value checks for EEPROM reads, so only the endianness conversion\n> cleanup is included for e1000e.\n> \n> drivers/net/ethernet/intel/e1000e/ethtool.c | 10 +++++++++-\n> 1 file changed, 9 insertions(+), 1 deletion(-)\n> \n> diff --git a/drivers/net/ethernet/intel/e1000e/ethtool.c\n> b/drivers/net/ethernet/intel/e1000e/ethtool.c\n> index dbed30943ef4..785d89477c43 100644\n> --- a/drivers/net/ethernet/intel/e1000e/ethtool.c\n> +++ b/drivers/net/ethernet/intel/e1000e/ethtool.c\n> @@ -583,13 +583,21 @@ static int e1000_set_eeprom(struct net_device\n> *netdev,\n> \t\t/* need read/modify/write of first changed EEPROM word\n> */\n> \t\t/* only the second byte of the word is being modified */\n> \t\tret_val = e1000_read_nvm(hw, first_word, 1,\n> &eeprom_buff[0]);\n> +\n> +\t\t/* Device's eeprom is always little-endian, word\n> addressable */\n> +\t\tle16_to_cpus(&eeprom_buff[0]);\n> +\n> \t\tptr++;\n> \t}\n> -\tif (((eeprom->offset + eeprom->len) & 1) && (!ret_val))\n> +\tif (((eeprom->offset + eeprom->len) & 1) && (!ret_val)) {\n> \t\t/* need read/modify/write of last changed EEPROM word */\n> \t\t/* only the first byte of the word is being modified */\n> \t\tret_val = e1000_read_nvm(hw, last_word, 1,\n> \t\t\t\t\t &eeprom_buff[last_word -\n> first_word]);\n> +\n> +\t\t/* Device's eeprom is always little-endian, word\n> addressable */\n> +\t\tle16_to_cpus(&eeprom_buff[last_word - first_word]);\n> +\t}\n> \n> \tif (ret_val)\n> \t\tgoto out;\n> --\n> 2.51.0\n\nReviewed-by: Aleksandr Loktionov ","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=osuosl.org header.i=@osuosl.org header.a=rsa-sha256\n header.s=default header.b=QQSGCVXf;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=osuosl.org\n (client-ip=140.211.166.136;

On big-endian systems, converting\nLE->CPU->LE would byte-swap the boundary words compared to the user's\nintended values. Does the patch also remove those loops, or is this\ncausing data corruption on big-endian architectures?\n\nThanks,\nTony","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=osuosl.org header.i=@osuosl.org header.a=rsa-sha256\n header.s=default header.b=bHuHeGMR;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=osuosl.org\n (client-ip=2605:bc80:3010::136;
