2013-01-10libc: add {get,set,swap,make}context user context manipulation functionsFlorian Fainelli

2012-12-11arm: clone: restore stack pointer just after return from syscallFilippo Arcidiacono
If the syscall returns with an error the stack pointer and r4 register are not restored because the instruction 'ldmnefd sp!, {r4}' is executed after branching to '__error' label. This bug has been spotted out by running './utstest clone 5' from LTP built with -fstack-protector-all compiler flag as log below: root@cortex-a9:/usr/tests/ltp/testcases/bin# ./utstest clone 5 stack smashing detected: ./utstest terminated() Regression introduced by commit e58798e107d652644629a1daaa95d76430808d53 Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Giuseppe Di Giore <giuseppe.di-giore@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2012-12-05xtensa: fix setjmp that didn't save all registers correctlyChris Zankel
Setjmp was only saving the lower order of registers (a0-a3) correctly, but not the higher ones (a4-a8/a12). The change also includes additional information, and renames many of the registers, so that setjmp and longjmp look more like the inverse of each other. Signed-off-by: Chris Zankel <chris@zankel.net>

2012-12-01update ptrace.h to latest from glibcJames Hogan
Update libc/sysdeps/linux/common/sys/ptrace.h to latest from glibc's sysdeps/unix/sysv/linux/sys/ptrace.h. This adds definitions for operations: - PTRACE_GETREGSET - PTRACE_SETREGSET - PTRACE_SEIZE - PTRACE_INTERRUPT - PTRACE_LISTEN And adds flags: - PTRACE_SEIZE_DEVEL And adds event codes: - PTRACE_EVENT_SECCOMP This is to allow access to the generic interface for accessing architecture specific regsets using the corresponding NT_* types, required for new Linux kernel architecture ports.

2012-11-29libc/stdlib: localize __unix_grantptMike Frysinger
When ASSUME_DEVPTS is disabled, we end up exporting __unix_grantpt and get a reloc to it from grantpt. Mark it static to fix all of that. Reported-by: Michael Deutschmann <michael@talamasca.ocis.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-11-18drop support for pre ISO-C compilersMike Frysinger
This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless. Really, the point of this is to stay in sync with what glibc did. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-11-12string/microblaze: Fix for little-endianSteve Bennett

2012-11-03xtensa: add missing atomic intrinsicsChris Zankel
Add more atomic intrinsics. These are mostly non 32-bit versions, which are not support by Xtensa. This file needs some more clean-up and consolidation. Signed-off-by: Chris Zankel <chris@zankel.net>
2012-11-03xtensa: sysdep.h needs to include sys/syscall.hChris Zankel
The Xtensa version of sysdep.h didn't include sys/syscall.h. This header file is, for example, needed by not-cancel.h, which uses the INTERNAL_SYSCALL macro. Signed-off-by: Chris Zankel <chris@zankel.net>
2012-11-03xtensa: add a stub user.h fileChris Zankel
Xtensa only supports the ELF binary format, so the user.h file isn't needed. However, it's included by other files, so provide a stub user.h. Signed-off-by: Chris Zankel <chris@zankel.net>

2012-10-31_scanf.c: Implement 'm' modifier for 'c' and '[' conversions.Will Newton

2012-10-02libc/sysdeps: add __kernel_long and __kernel_ulongChris Packham
Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various exported header files were updated to use these new types. Add the definitions for __kernel_long_t and __kernel_ulong_t to the relevant kernel_types.h headers. This change was automated with the following scriptlet git grep --name-only 'typedef.*__kernel_old_dev_t' \ | xargs sed -i '/typedef.*__kernel_old_dev_t/ a\ typedef long\t\t__kernel_long_t;\ typedef unsigned long\t__kernel_ulong_t;' Whitespace in arm, avr32, hppa, sparc was then manually fixed up. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> -- Here's a cleaned up patch which should get the whitespace right. I'm a bit iffy about the sparc changes they make sense to me but it's not a platform I have access to.
