musl: fix mips vdso handling

2016-01-25T23:26:19Z

mips returns -ENOSYS in case it can not handle the vdso call and wants the libc to call the original syscall in such a case. This fixes the patch to add such handling. I hope this fixes the random reboots I got. Signed-off-by: Hauke Mehrtens SVN-Revision: 48501

musl: Add format attribute to some function declarations

2016-01-24T00:05:14Z

GCC and Clang are able to check the format arguments given to a function and warn the user if there is a error in the format arguments or if there is a potential uncontrolled format string security problem in the code. GCC does this automatically for some functions like printf(), but it is also possible to annotate other functions in a way that it will check them too. This feature is used by glibc for many functions. This patch adds the attribute to the some functions of musl expect for these functions where gcc automatically adds it. GCC automatically adds checks for these functions: printf, fprintf, sprintf, scanf, fscanf, sscanf, strftime, vprintf, vfprintf and vsprintf. The documentation from gcc is here: https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html The documentation from Clang is here: http://clang.llvm.org/docs/AttributeReference.html#format-gnu-format Signed-off-by: Hauke Mehrtens SVN-Revision: 48467

musl: mips: add vdso support

2016-01-23T23:48:55Z

vdso support is available on mips starting with kernel 4.4, see kernel commit a7f4df4e21 "MIPS: VDSO: Add implementations of gettimeofday() and clock_gettime()" for details. These are my micro benchmark results for 1.000.000 calls to clock_gettime(CLOCK_MONOTONIC, &tp) without vdso: root@OpenWrt:/# time ./vdso-test real 0m 0.95s user 0m 0.24s sys 0m 0.70s with vdso: root@OpenWrt:/# time /usr/bin/vdso-test real 0m 0.35s user 0m 0.34s sys 0m 0.00s Signed-off-by: Hauke Mehrtens SVN-Revision: 48466
