s390/net: move pnet constants

2019-02-08T02:06:18+00:00

There is no need to define these PNETID related constants in the pnet.h file, since they are just used locally within pnet.c. Just code cleanup, no functional change. Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

s390: bpf: fix JMP32 code-gen

2019-02-04T17:45:09+00:00

Commit 626a5f66da0d19 ("s390: bpf: implement jitting of JMP32") added JMP32 code-gen support for s390. However it triggers the warning below due to some unusual gotos in the original s390 bpf jit code. Add a couple of additional "is_jmp32" initializations to fix this. Also fix the wrong opcode for the "llilf" instruction that was introduced with the same commit. arch/s390/net/bpf_jit_comp.c: In function 'bpf_jit_insn': arch/s390/net/bpf_jit_comp.c:248:55: warning: 'is_jmp32' may be used uninitialized in this function [-Wmaybe-uninitialized] _EMIT6(op1 | reg(b1, b2) << 16 | (rel & 0xffff), op2 | mask); \ ^ arch/s390/net/bpf_jit_comp.c:1211:8: note: 'is_jmp32' was declared here bool is_jmp32 = BPF_CLASS(insn->code) == BPF_JMP32; Fixes: 626a5f66da0d19 ("s390: bpf: implement jitting of JMP32") Cc: Jiong Wang Cc: Martin Schwidefsky Signed-off-by: Heiko Carstens Acked-by: Jiong Wang Acked-by: David S.

Pull s390 updates from Heiko Carstens: "Since Martin is on vacation you get the s390 pull request from me: - Host large page support for KVM guests. As the patches have large impact on arch/s390/mm/ this series goes out via both the KVM and the s390 tree. - Add an option for no compression to the "Kernel compression mode" menu, this will come in handy with the rework of the early boot code. - A large rework of the early boot code that will make life easier for KASAN and KASLR. With the rework the bootable uncompressed image is not generated anymore, only the bzImage is available. For debuggung purposes the new "no compression" option is used. - Re-enable the gcc plugins as the issue with the latent entropy plugin is solved with the early boot code rework. - More spectre relates changes: + Detect the etoken facility and remove expolines automatically. + Add expolines to a few more indirect branches. - A rewrite of the common I/O layer trace points to make them consumable by 'perf stat'. - Add support for format-3 PCI function measurement blocks. - Changes for the zcrypt driver: + Add attributes to indicate the load of cards and queues. + Restructure some code for the upcoming AP device support in KVM. - Build flags improvements in various Makefiles. - A few fixes for the kdump support. - A couple of patches for gcc 8 compile warning cleanup. - Cleanup s390 specific proc handlers. - Add s390 support to the restartable sequence self tests. - Some PTR_RET vs PTR_ERR_OR_ZERO cleanup. - Lots of bug fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (107 commits) s390/dasd: fix hanging offline processing due to canceled worker s390/dasd: fix panic for failed online processing s390/mm: fix addressing exception after suspend/resume rseq/selftests: add s390 support s390: fix br_r1_trampoline for machines without exrl s390/lib: use expoline for all bcr instructions s390/numa: move initial setup of node_to_cpumask_map s390/kdump: Fix elfcorehdr size calculation s390/cpum_sf: save TOD clock base in SDBs for time conversion KVM: s390: Add huge page enablement control s390/mm: Add huge page gmap linking support s390/mm: hugetlb pages within a gmap can not be freed KVM: s390: Add skey emulation fault handling s390/mm: Add huge pmd storage key handling s390/mm: Clear skeys for newly mapped huge guest pmds s390/mm: Clear huge page storage keys on enable_skey s390/mm: Add huge page dirty sync support s390/mm: Add gmap pmd invalidation and clearing s390/mm: Add gmap pmd notification bit setting s390/mm: Add gmap pmd linking ...

s390: fix br_r1_trampoline for machines without exrl

2018-08-07T11:38:16+00:00

For machines without the exrl instruction the BFP jit generates code that uses an "br %r1" instruction located in the lowcore page. Unfortunately there is a cut & paste error that puts an additional "larl %r1,.+14" instruction in the code that clobbers the branch target address in %r1. Remove the larl instruction.

bpf, s390: fix potential memleak when later bpf_jit_prog fails

2018-06-29T17:47:35+00:00

If we would ever fail in the bpf_jit_prog() pass that writes the actual insns to the image after we got header via bpf_jit_binary_alloc() then we also need to make sure to free it through bpf_jit_binary_free() again when bailing out. Given we had prior bpf_jit_prog() passes to initially probe for clobbered registers, program size and to fill in addrs arrray for jump targets, this is more of a theoretical one, but at least make sure this doesn't break with future changes.
