** Summary changed: - change udev rules for rpmb partitions + Fix udev rules to consider mmc rpmb partitions
** Description changed: - As per JESD 4.5 spec for eMMC devices, - There is a new partitions as part of eMMC storage devices it self. (Further details please refer eMMC spec) + As per JEDEC 4.5 spec for eMMC devices, + There is a new partitions as part of eMMC storage devices it self. (Further details please refer eMMC spec) *In Linux Kernel@ 3.10.33, mmc driver has created a new partitions with "mmcblkXrpmb" if device expresses it support of RPMB. Issues observed: issue 1: RPMB (Replay Protected Memory Block), A signed access to a Replay Protected Memory Block is provided. This function provides means for the system to store data to the specific memory area in an authenticated and replay protected manner. In that case, any read/write access to this partition device will report errors. issue 2: - The by-path, line is wrongly mapping to platform-sdhci-tegra.1 -> mmcblk2rpmb were as + The by-path, line is wrongly mapping to platform-sdhci-tegra.1 -> mmcblk2rpmb were as it should be platform-sdhci-tegra.1 -> mmcblk2 - ls -l /dev/disk/by-path/ total 0 lrwxrwxrwx 1 root root 17 Jan 3 2000 platform-sdhci-tegra.1 -> ../../mmcblk2rpmb lrwxrwxrwx 1 root root 15 Jan 3 2000 platform-sdhci-tegra.1-part1 -> ../../mmcblk2p1 lrwxrwxrwx 1 root root 13 Jan 3 2000 platform-sdhci-tegra.2 -> ../../mmcblk1 lrwxrwxrwx 1 root root 15 Jan 3 2000 platform-sdhci-tegra.2-part1 -> ../../mmcblk1p1 lrwxrwxrwx 1 root root 17 Jan 3 2000 platform-sdhci-tegra.3 -> ../../mmcblk0rpmb lrwxrwxrwx 1 root root 15 Jan 3 2000 platform-sdhci-tegra.3-part1 -> ../../mmcblk0p1 lrwxrwxrwx 1 root root 15 Jan 3 2000 platform-sdhci-tegra.3-part2 -> ../../mmcblk0p2 - We have locally resolved in our platform in this file 60-persistent- storage.rules For issue 1: (with this rule) # skip block read for partitions of type rpmb KERNEL=="mmcblk[0-9]rpmb", SUBSYSTEM=="block", GOTO="persistent_storage_end" For issue 2: ENV{DEVTYPE}=="disk", ENV{ID_PATH}=="?*", KERNEL=="mmcblk[0-9]rpmb", SYMLINK+="disk/by-path/$env{ID_PATH}-rpmb" ENV{DEVTYPE}=="disk", ENV{ID_PATH}=="?*", KERNEL!="mmcblk[0-9]rpmb", SYMLINK+="disk/by-path/$env{ID_PATH}" - Please consider this issues fix in next udev release . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1333140 Title: Fix udev rules to consider mmc rpmb partitions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1333140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
