Bug in sigpending.c (glibc 2.1.3, 2.2.5)

[Michael Kerrisk]

Hello,
This is a bug report for the sigpending() implementation in glibc 2.1.3& 
2.2.5

Linux Kernel 2.2.14, SuSE 6.4 distribution

Files:
sysdeps/unix/sysv/linux/sigpending.c
in: GLIBC 2.1.3 (same error appears still to be present in GLIBC 2.2.5, 
though I have not compiled against this library version)

Synopsis: calls to sigpending() incorrectly return the mask of pending 
signals.  Instead of returning the 64 bit mask of signals, only the first 
32 bits are correctly returned (thus real-time signals are incorrectly 
handled).  It appears that the library routine is incorrectly calling 
sys_sigpending() instead of sys_rt_sigpending().

Solution: It seems to me that the line:

# ifdef __NR_rt_pending

should read

# ifdef __NR_rt_sigpending

Cheers

Michael Kerrisk
