* sparc: bpf_jit_comp: can call module_free() from any contextEric Dumazet2013-05-171-17/+3
| | | | | | | | module_free()/vfree() takes care of details, we no longer need a wrapper and a work_struct. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* filter: bpf_jit_comp: refactor and unify BPF JIT image dump outputDaniel Borkmann2013-03-211-5/+1
| | | | | | | | | | | | | | | | | | If bpf_jit_enable > 1, then we dump the emitted JIT compiled image after creation. Currently, only SPARC and PowerPC has similar output as in the reference implementation on x86_64. Make a small helper function in order to reduce duplicated code and make the dump output uniform across architectures x86_64, SPARC, PPC, ARM (e.g. on ARM flen, pass and proglen are currently not shown, but would be interesting to know as well), also for future BPF JIT implementations on other archs.

* 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>
* net: filter: Fix some minor issues in sparc JIT.David S. Miller2012-04-173-5/+6
| | | | | | | | | | | | | | | 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>
