[CVE-2009-0029] System call wrapper special cases · 6673e0c3

Heiko Carstens authored Jan 14, 2009

System calls with an unsigned long long argument can't be converted with
the standard wrappers since that would include a cast to long, which in
turn means that we would lose the upper 32 bit on 32 bit architectures.
Also semctl can't use the standard wrapper since it has a 'union'
parameter.

So we handle them as special case and add some extra wrappers instead.

[CVE-2009-0029] System call wrapper infrastructure · 1a94bc34

Heiko Carstens authored Jan 14, 2009

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

By selecting HAVE_SYSCALL_WRAPPERS architectures can activate
system call wrappers in order to sign extend system call arguments.

All architectures where the ABI defines that the caller of a function
has to perform sign extension probably need this.

[CVE-2009-0029] Make sys_pselect7 static · c9da9f21

Heiko Carstens authored Jan 14, 2009

Not a single architecture has wired up sys_pselect7 plus it is the
only system call with seven parameters. Just make it static and
rename it to do_pselect which will do the work for sys_pselect6.

Remove __attribute__((weak)) from common code sys_pipe implemantation.
IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations
with the same name. Just rename them.
For sys_pipe2 there is no architecture specific implementation.

[CVE-2009-0029] Convert all system calls to return a long · 2ed7c03e

Heiko Carstens authored Jan 14, 2009

Convert all system calls to return a long. This should be a NOP since all
converted types should have the same size anyway.
With the exception of sys_exit_group which returned void. But that doesn't
matter since the system call doesn't return.
