* ARM: Don't apply pointer encryption to the frame pointerWill Newton2014-01-144-11/+10
| | | | | | | | | | | | | | | | | | | | | The frame pointer register is rarely used for that purpose on ARM and applications that look at the contents of the jmp_buf may be relying on reading an unencrypted value. For example, Ruby uses the contents of jmp_buf to find the root set for garbage collection so relies on this pointer value being unencrypted. Without this patch the Ruby testsuite fails with a segmentation fault. ports/ChangeLog.arm: 2013-01-14 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S: Don't apply pointer encryption to fp register. * sysdeps/arm/setjmp.S: Likewise. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Add fp to register list, remove a4. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE_LOAD): New macro.

* Use separate libc.abilist for MIPS o32 soft float.Joseph Myers2014-01-072-0/+2259
| | | | | | | | | | | | | | | | | | | | Examining MIPS test results showed an ABI test failure that I must have missed in 2.18 testing: hard-float and soft-float o32 no longer have the same set of symbols (because of the __mips_fpu_getcw and __mips_fpu_setcw functions, present for hard-float only, used by fpu_control.h for hard-float MIPS16) and so need separate ABI test baselines (they always were ABI-incompatible - the function-calling interface is different - but previously had the same set of symbols and versions so didn't need separate baselines). Tested for hard-float and soft-float o32. * sysdeps/unix/sysv/linux/mips/mips32/nptl/libc.abilist: Move to .... * sysdeps/unix/sysv/linux/mips/mips32/fpu/nptl/libc.abilist: ... here. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/nptl/libc.abilist: New file.

* ia64: add __ prefix to pt_all_user_regs/ia64_fpreg [BZ #762]Mike Frysinger2014-01-063-5/+5
| | | | | | | | | | | | This addresses a long standing collision between userspace headers and kernel headers only on ia64 systems. All other types have a __ prefix in the ptrace headers except these two. Let's finally namespace these. Verified that at least strace still builds after this change, as well as after deleting all the struct hacks it has specifically for ia64.

* ptrace.h: add __ prefix to ptrace_peeksiginfo_argsMike Frysinger2014-01-063-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | All the other ptrace structures in this file have a __ prefix except this new one. This in turn causes build problems for most packages that try to use ptrace such as strace: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \ -I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \ -MF .deps/process.Tpo -c -o process.o ../../process.c In file included from ../../process.c:63:0: /usr/include/linux/ptrace.h:58:8: error: redefinition of 'struct ptrace_peeksiginfo_args' struct ptrace_peeksiginfo_args { ^ In file included from ../../defs.h:159:0, from ../../process.c:37: /usr/include/sys/ptrace.h:191:8: note: originally defined here struct ptrace_peeksiginfo_args ^ Since this struct was introduced in glibc-2.18, there shouldn't be any real regressions with adding the __ prefix.

* ia64: fix build failure after async tls updatesMike Frysinger2014-01-041-4/+4
| | | | | | | | | | The recent commit 7f507ee17aee720fa423fa38502bc3caa0dd03d7 added a new local variable "offset" to tls_get_addr_tail. This conflicts with the ia64 code which also declares an offset code inline in this func. So have the ia64 code rename its local vars with a prefix that shouldn't collide with anything else in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* MIPS: Fix RLIM64_INFINITY constant for O32 and N32 ABIsAurelien Jarno2013-11-277-30/+60
| | | | | | | Fix the RLIM64_INFINITY constant for O32 and N32 ABIs to match the kernel one. Change the getrlimit64/setrlimit64 into old compat symbols, and provide the Linux generic getrlimit64/setrlimit64 functions as GLIBC_2_19 version.
* MIPS: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constantAurelien Jarno2013-11-272-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RLIM64_INFINITY was supposed to be a glibc convention rather than anything seen by the kernel, but it ended being passed to the kernel through the prlimit64 syscall. On O32 and N32 ABIs, we therefore end-up with different values on the userland and kernel side: * On the kernel side, the value is defined for all architectures as include/uapi/linux/resource.h: #define RLIM64_INFINITY (~0ULL) * On the GNU libc side, the value is defined in ports/sysdeps/unix/sysv/linux/mips/bits/resource.h: For the O32 and N32 ABI: # define RLIM64_INFINITY 0x7fffffffffffffffULL and for the N64 ABI: # define RLIM64_INFINITY 0xffffffffffffffffUL This was not a problem until the prlimit64 syscall was wired in the 2.6.36 kernel. Given the GLIBC uses the prlimit64 syscall to implement getrlimit64 and setrlimit64, pam_limits.so is setting the limits to a very big value instead of infinity. As a normal user process can later only decrease the value and not increase it, it will later get and EPERM error when trying to set the value to infinity with setrlimit. The GLIBC has this constant for more than 7 years, and as it is defined in a header file, it means a lot of binaries are in the wild. This patch fixes that by adding a wrapper to fix the value passed to or received from the kernel, before or after calling the prlimit64 syscall.

* Don't use broken DL_AUTO_FUNCTION_ADDRESS()Guy Martin2013-11-214-48/+64
| | | | | | | | | | | | On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the variable fptr[2] in it's own scope. The content of fptr[] is thus undefined right after the macro exits. Newer gcc's (>= 4.7) reuse the stack space of this variable triggering a segmentation fault in dl-init.c:69. To fix this we rewrite the macros to make the call directly to init and fini without needing to pass back a constructed function pointer.
* linux-generic: fix alignment of struct stat/statfs for nios2Chung-Lin Tang2013-11-202-6/+6
| | | | | | | | | The hard alignment of 8 was appropriate for most platforms for which 8-byte values are 8-byte aligned, but this is not true for the nios2 platform, so only align to the alignment of the 8-byte type on the platform. Remove the explicit alignment of struct statfs as it's redundant.
