| |
In commit ee6a093222549ac0c72cfd296c69fa5e7d6daa34 the syscall wrappers infrastructure was introduced.
A typical definition is something like this (from Ralf's patch):
SYSCALL_DEFINE6(32_ipc, u32, call, long, first, long, second, long, third, unsigned long, ptr, unsigned long, fifth) { . . .
This creates a symbol sys_32_ipc. The old name of the symbol is sys32_ipc (note the change in the number of '_').
For the mips64 kernel the syscall table for o32 ABI executable contains:
. . . PTR sys32_ipc . . .
This is now linked to the sys32_ipc function in kernel/sys_ni.c which kindly returns ENOSYS.
The long and short of the problem is that the is now a kernel wide mismatch in function names between the names created by SYSCALL_DEFINE*, the syscall tables and kernel/sys_ni.c.
I am not sure what the best solution is, but something should probably be done to un-break things.
Thanks, David Daney
