In order to use the memory leak detection code, a user-mode TA needs two things: - A version of libutils.a that was built with malloc debug code. This is taken care of by ta/ta.mk which sets ENABLE_MDBG=1 when CFG_TEE_TA_MALLOC_DEBUG is 'y'. - The proper declarations for mdbg_malloc(), mdbg_free(), mdbg_check() etc. as well as the macro redefinitions for malloc(), free() etc. in the header files when the TA is built.

2017-10-06Dump call stack on TA panicJerome Forissier
Adds support for dumping the call stack of a user-mode TA when it panics. Stack unwinding happens in kernel mode by re-using abort_print_error() in core/arch/arm/kernel/abort.c. Like for abort dumps, the helper script scripts/symbolize.py may be used to obtain source-level information. This feature is enabled by default. Set CFG_UNWIND=n to disable it (or CFG_TEE_CORE_DEBUG=n). In libutee, the utee_panic() syscall wrapper is renamed __utee_panic() and now takes an additional parameters: a stack pointer, in addition to the panic code. utee_panic() is written in assembly and pushes some registers onto the stack before calling __utee_panic(). When it is time to return from syscall_panic(), tee_svc_sys_return_helper() uses the stack pointer to get the information needed to unwind the TA stack. A struct abort_info is created and abort_print_error() is called.

Removes all the TUI-related code from libutee (lib/libutee/tui), as well as its dependencies: lib/libpng and lib/libzlib. Two reasons for this: 1. This is far from being a complete and testable TUI implementation. In other words, it is dead code, more or less. 2. lib/libzlib (version 1.2.8) contains several CVE vulnerabilities. Even if the code is not used, it may trigger some code analysis tools and is a problem for some projects.

2017-01-09Make sure "make clean" removes everything "make" has created under $(O)Jerome Forissier
"make clean" would leave behind some files and many directories. Fix this by correctly tracking the files and directories created under $(O) during the build process: - Fix incorrect file names in $(cleanfiles) and add a few missing ones. - Introduce a makefile macro: $(cleandirs-for-rmdir), defined in a new file: mk/cleandirs.mk. It returns the list of directories that should be removed, given a list of files. The clean target removes the files, then all the directories in depth- first order. $(O) is also removed, if found to be empty. Note that a more straightforward approach was discussed in [1]: use "rm -rf $(O)/some_dir" and get rid of the whole file and directory tracking via $(cleanfiles) and $(cleandirs). Although it was agreed it would be safe, doing so would necessarily break the backward compatibility for build scripts relying on "make O=<some path>", due to the additional level ($(O)/some_dir). Finally, mk/cleandirs.mk is exported to the TA dev kit and the clean rule for the TAs is updated.

Currently, to build a 64-bit TEE core (as well as mixed 32- and 64-bit TA libraries, which are automatically enabled in this case), one has to set too many compiler variables: $ make PLATFORM=hikey CFG_ARM64_core=y \ CROSS_COMPILE_core=aarch64-linux-gnu- \ CROSS_COMPILE_ta_arm64=aarch64-linux-gnu- This commit introduces two variables, CROSS_COMPILE32 and CROSS_COMPILE64. They take appropriate default values, so that the above line may be simplified as: $ make PLATFORM=hikey CFG_ARM64_core=y The change remains compatible with previous builds, i.e., CROSS_COMPILE can still be used to define the 32-bit compiler because CROSS_COMPILE32 defaults to $(CROSS_COMPILE). Similarly, CROSS_COMPILE_core and CROSS_COMPILE_ta_arm{32,64} are still used so they may be overridden too.
