Bug ID: 18472
Summary: Obsolete syscall wrappers should be compat symbols
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Host: *-*-linux*
The following Linux syscalls are obsolete and the corresponding wrappers in
glibc should be compat symbols: bdflush create_module get_kernel_syms
query_module uselib. (Note that syscalls.list doesn't currently have support
for compat symbols with SHLIB_COMPAT conditionals, so that would need adding;
new architectures should not have these symbols at all.)
The syscalls create_module get_kernel_syms query_module no longer exist as of
Linux 2.6. bdflush does nothing as of Linux 2.6, and uselib was part of the
mechanism for loading a.out shared libraries and is irrelevant with ELF. Thus,
all of those syscalls are useless with current glibc.
