* linux-user: add support of binfmt_misc 'O' flagLaurent Vivier2013-09-241-6/+2Star
| | | | | | | | | | | | | | | | | The binfmt_misc module can calculate the credentials and security token according to the binary instead of to the interpreter if the 'C' flag is enabled. To be able to execute non-readable binaries, this flag implies 'O' flag. When 'O' flag is enabled, bintfmt_misc opens the file for reading and pass the file descriptor to the interpreter.

* linux-user: If loading fails, print error as string, not numberPeter Maydell2012-10-121-4/+4
| | | | | | | | | | | | | | If the attempt to load the guest executable fails, print the error message as a string, not a number. This requires us to fix a couple of places in loader_exec() where we were returning -1 instead of a valid negative errno. The change allows us to drop the "Unknown binary format" message because the strerror-enhanced message is now a more self-explanatory "Error while loading $guest-binary: Exec format error".

* linux-user/elfload.c: Don't memset(NULL..) if malloc() failedPeter Maydell2011-11-111-1/+1
| | | | | | | | | | | If a malloc() in copy_elf_strings() failed we would call memset() before the "did malloc fail?" check. Fix this by moving to the glib alloc/free routines for this memory so we can use g_try_malloc0 rather than having a separate memset(). Spotted by Coverity (see bug 887883).

* linux-user: Reduce lseek+reads while loading elf files.Richard Henderson2010-07-291-10/+7Star
| | | | | | | | | Define BPRM_BUF_SIZE to 1k and read that amount initially. If the data we want from the binary is in this buffer, use it instead of reading from the file again. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
* linux-user: Remove ELFLOAD32.Richard Henderson2010-04-251-5/+1Star
| | | | | | | | | | | The ABI-specific types used by linux_binprm and image_info are different after forcing TARGET_ABI32 on. Which means that the parameters that load_elf_binary_multi sees are not those that loader_exec passed. This is inherently broken and is more trouble than it's worth fixing.
