Subject: [PATCH 1/2] ARM: 6329/1: wire up sys_accept4() on ARM
|
|
|
|
sys_accept4() was added in kernel 2.6.28, but ARM was not updated
|
|
to include it. The number and types of parameters is such that
|
|
no ARM-specific processing is needed, so wiring up sys_accept4()
|
|
just requires defining __NR_accept4 and adding a direct call in
|
|
the syscall entry table.
|
|
|
|
Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original
|
|
accept4() test program, modified to define __NR_accept4 for ARM.
|
|
|
|
Using the updated unistd.h also eliminates a warning then building
|
|
glibc (2.10.2 and newer) about accept4() being unimplemented.
|
|
|
|
Upstream-Status: Backport [2.6.36]
