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>

2012-10-02libc/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.
