* sparc: bpf_jit_comp: add VLAN instructions for BPF JITDaniel Borkmann2012-11-061-0/+19
| | | | | | | | This patch is a follow-up for patch "net: filter: add vlan tag access" to support the new VLAN_TAG/VLAN_TAG_PRESENT accessors in BPF JIT. Signed-off-by: Daniel Borkmann <daniel.borkmann@tik.ee.ethz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: bpf_jit_comp: add XOR instruction for BPF JIT JITDaniel Borkmann2012-09-271-0/+4
| | | | | | | | This patch is a follow-up for patch "filter: add XOR instruction for use with X/K" that implements BPF SPARC JIT parts for the BPF XOR operation. Signed-off-by: Daniel Borkmann <daniel.borkmann@tik.ee.ethz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

* net: filter: Fix some more small issues in sparc JIT.David S. Miller2012-04-173-44/+84
| | | | | | | | | | | | | | | | | | | | | Fix mixed space and tabs. Put bpf_jit_load_*[] externs into bpf_jit.h "while(0)" --> "while (0)" "COND (X)" --> "COND(X)" Document branch offset calculations, and bpf_error's return sequence. Document the reason we need to emit three nops between the %y register write and the divide instruction. Remove erroneous trailing semicolons from emit_read_y() and emit_write_y(). Based upon feedback from Sam Ravnborg. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | Correct conventions comments. %o4 and %o5 were swapped, %g3 was not documented. Use r_TMP instead of r_SKB_DATA + r_OFF where possible in assembler stubs. Correct discussion of %o4 and %o5 in one of bpf_jit_compile()'s comments. Based upon feedback from Richard Mortimer. Signed-off-by: David S. Miller <davem@davemloft.net>
