2016-01-29linux-user: Clean up includesPeter Maydell1-7/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-10-git-send-email-peter.maydell@linaro.org
2015-09-28linux-user: remove MAX_ARG_PAGES limitStefan Brüns1-7/+0
Instead of creating a temporary copy for the whole environment and the arguments, directly copy everything to the target stack. For this to work, we have to change the order of stack creation and copying the arguments.

2013-09-24linux-user: add support of binfmt_misc 'O' flagLaurent Vivier1-6/+2
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.

2012-10-12linux-user: If loading fails, print error as string, not numberPeter Maydell1-4/+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".

2011-11-11linux-user/elfload.c: Don't memset(NULL..) if malloc() failedPeter Maydell1-1/+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).

2011-01-07Remove dead code for ARM semihosting commandline handlingWolfgang Schildbach1-2/+0
There are some bits in the code which were used to store the commandline for the semihosting call. These bits are now write-only and can be removed.

2010-07-29linux-user: Reduce lseek+reads while loading elf files.Richard Henderson1-10/+7
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>
2010-04-25linux-user: Remove ELFLOAD32.Richard Henderson1-5/+1
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.
