2014-03-26linux-user: Correct DLINFO_ITEMSJames Hogan
Commit a07c67dfccb1 (Implement AT_CLKTCK.) back in March 2008 added a new auxvec entry but didn't increment DLINFO_ITEMS, so it's been out of sync ever since. Bump it up to 14 so that it matches the number of NEW_AUX_ENT's that need to be counted in create_elf_tables().

Coverity complained about local variable key which was only partially initiated. Only key.st_value was set.

2011-06-21linux-user: Define AT_RANDOM to support target stack protection mechanism.Laurent ALFONSI
The dynamic linker from the GNU C library v2.10+ uses the ELF auxiliary vector AT_RANDOM [1] as a pointer to 16 bytes with random values to initialize the stack protection mechanism. Technically the emulated GNU dynamic linker crashes due to a NULL pointer derefencement if it is built with stack protection enabled and if AT_RANDOM is not defined by the QEMU ELF loader. [1] This ELF auxiliary vector was introduced in Linux v2.6.29. This patch can be tested with the code above: #include <elf.h> /* Elf*_auxv_t, AT_RANDOM, */ #include <stdio.h> /* printf(3), */ #include <stdlib.h> /* exit(3), EXIT_*, */ #include <stdint.h> /* uint8_t, */ #include <string.h> /* memcpy(3), */ #if defined(__LP64__) || defined(__ILP64__) || defined(__LLP64__) # define Elf_auxv_t Elf64_auxv_t #else # define Elf_auxv_t Elf32_auxv_t #endif main(int argc, char* argv[], char* envp[]) { Elf_auxv_t *auxv; /* *envp = NULL marks end of envp. */ while (*envp++ != NULL); /* auxv->a_type = AT_NULL marks the end of auxv. */ for (auxv = (Elf_auxv_t *)envp; auxv->a_type != AT_NULL; auxv++) { if (auxv->a_type == AT_RANDOM) { int i; uint8_t rand_bytes[16]; printf("AT_RANDOM is: 0x%x\n", auxv->a_un.a_val); memcpy(rand_bytes, (const uint8_t *)auxv->a_un.a_val, sizeof(rand_bytes)); printf("it points to: "); for (i = 0; i < 16; i++) { printf("0x%02x ", rand_bytes[i]); } printf("\n"); exit(EXIT_SUCCESS); } } exit(EXIT_FAILURE); } Changes introduced in v2 and v3: * Fix typos + thinko (AT_RANDOM is used for stack canary, not for ASLR) * AT_RANDOM points to 16 random bytes stored inside the user stack. * Add a small test program.

2011-06-21linux-user: Handle images where lowest vaddr is not page alignedPeter Maydell
Fix a bug in the linux-user ELF loader code where it was not correctly handling images where the lowest vaddr to be loaded was not page aligned. The problem was that the code to probe for a suitable guest base address was changing the 'loaddr' variable (by rounding it to a page boundary), which meant that the load bias would then be incorrectly calculated unless loaddr happened to already be page-aligned. Binaries generated by gcc with the default linker script do start with a loadable segment at a page-aligned vaddr, so were unaffected. This bug was noticed with a binary created by the Google Go toolchain for ARM. We fix the bug by refactoring the "probe for guest base" code out into its own self-contained function.
