2018-05-25	s390: use expoline thunks in the BPF JIT	Martin Schwidefsky	1	-6/+10
	[ Upstream commit de5cb6eb514ebe241e3edeb290cb41deb380b81d ] The BPF JIT need safe guarding against spectre v2 in the sk_load_xxx assembler stubs and the indirect branches generated by the JIT itself need to be converted to expolines.

2015-04-15	s390/bpf: Add s390x eBPF JIT compiler backend	Michael Holzheu	1	-108/+89

2015-01-15	s390/bpf: Zero extend parameters before calling C function	Michael Holzheu	1	-4/+6
	The s390x ABI requires to zero extend parameters before functions are called. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2015-01-15	s390/bpf: Fix sk_load_byte_msh()	Michael Holzheu	1	-4/+4
	In sk_load_byte_msh() sk_load_byte_slow() is called instead of sk_load_byte_msh_slow(). Fix this and call the correct function. Besides of this load only one byte instead of two and fix the comment.

2015-01-15	s390/bpf: Fix offset parameter for skb_copy_bits()	Michael Holzheu	1	-0/+2
	Currently the offset parameter for skb_copy_bits is changed in sk_load_word() and sk_load_half(). Therefore it is not correct when calling skb_copy_bits(). Fix this and use the original offset for the function call. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2015-01-15	s390/bpf: Fix skb_copy_bits() parameter passing	Michael Holzheu	1	-10/+10
	The skb_copy_bits() function has the following signature: int skb_copy_bits(const struct sk_buff skb, int offset, void to, int len) Currently in bpf_jit.S the "to" and "len" parameters have been exchanged. So fix this and call the function with the correct parameters. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
