From d13b6cf29c71412adac3b0dca5eddcd6c75f5163 Mon Sep 17 00:00:00 2001 From: Bowgo Tsai Date: Fri, 10 Mar 2017 16:00:40 +0800 Subject: recovery: replacing fs_mgr_read_fstab() with new fs_mgr APIs The fstab settings of early-mounted partitions (e.g., /vendor) will be in kernel device tree. Switch to the new API to get the whole settings with those in device tree: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab") The original default /fstab.{ro.hardware} might be moved to /vendor/etc/. or /odm/etc/. Use another new API to get the default fstab instead of using the hard-coded /fstab.{ro.hardware}. This API also includes the settings from device tree: fs_mgr_read_fstab_default() Bug: 35811655 Test: boot sailfish recovery Change-Id: Iaa56ac7f7b4c4dfc7180c65f03e9a37b94f1de09 --- bootloader_message/bootloader_message.cpp | 23 +++++------------------ 1 file changed, 5 insertions(+), 18 deletions(-) (limited to 'bootloader_message/bootloader_message.cpp') diff --git a/bootloader_message/bootloader_message.cpp b/bootloader_message/bootloader_message.cpp index b873d3dc3..d8086be28 100644 --- a/bootloader_message/bootloader_message.cpp +++ b/bootloader_message/bootloader_message.cpp @@ -29,27 +29,14 @@ #include #include -static struct fstab* read_fstab(std::string* err) { - std::string ro_hardware = android::base::GetProperty("ro.hardware", ""); - if (ro_hardware.empty()) { - *err = "failed to get ro.hardware"; - return nullptr; - } - // The fstab path is always "/fstab.${ro.hardware}". - std::string fstab_path = "/fstab." + ro_hardware; - struct fstab* fstab = fs_mgr_read_fstab(fstab_path.c_str()); - if (fstab == nullptr) { - *err = "failed to read " + fstab_path; - } - return fstab; -} - static std::string get_misc_blk_device(std::string* err) { - struct fstab* fstab = read_fstab(err); - if (fstab == nullptr) { + std::unique_ptr fstab(fs_mgr_read_fstab_default(), + fs_mgr_free_fstab); + if (!fstab) { + *err = "failed to read default fstab"; return ""; } - fstab_rec* record = fs_mgr_get_entry_for_mount_point(fstab, "/misc"); + fstab_rec* record = fs_mgr_get_entry_for_mount_point(fstab.get(), "/misc"); if (record == nullptr) { *err = "failed to find /misc partition"; return ""; -- cgit v1.2.3
