False-positive Bluetooth messages fix in stable kernels

by Pavel Skripkin

Dear Greg and Sasha, can you, please, cherry-pick following commit from Linus' tree: commit 899663be5e75dc0174dc8bda0b5e6826edf0b29a with subject line "Bluetooth: refactor malicious adv data check". There is missing Fixes: tag inside commit log, which causes this patch to not go to stable trees, but it actually fixes false-positive messages in dmesg. I've seen 2 reports and I've asked reporters to test this patch and they have reported, that this patch actually fixes the problem [1] (second report was private, so I can't refer it there) [1] https://lore.kernel.org/linux-bluetooth/CAC2ZOYuXg4btk9PaE3whmP7JnntsixEvDu… With regards, Pavel Skripkin

[PATCH 4.14] bpf: fix truncated jump targets on heavy expansions

by Alessio Balsini

From: Daniel Borkmann <daniel(a)iogearbox.net> commit 050fad7c4534c13c8eb1d9c2ba66012e014773cb upstream. Recently during testing, I ran into the following panic: [ 207.892422] Internal error: Accessing user space memory outside uaccess.h routines: 96000004 [#1] SMP [ 207.901637] Modules linked in: binfmt_misc [...] [ 207.966530] CPU: 45 PID: 2256 Comm: test_verifier Tainted: G W 4.17.0-rc3+ #7 [ 207.974956] Hardware name: FOXCONN R2-1221R-A4/C2U4N_MB, BIOS G31FB18A 03/31/2017 [ 207.982428] pstate: 60400005 (nZCv daif +PAN -UAO) [ 207.987214] pc : bpf_skb_load_helper_8_no_cache+0x34/0xc0 [ 207.992603] lr : 0xffff000000bdb754 [ 207.996080] sp : ffff000013703ca0 [ 207.999384] x29: ffff000013703ca0 x28: 0000000000000001 [ 208.004688] x27: 0000000000000001 x26: 0000000000000000 [ 208.009992] x25: ffff000013703ce0 x24: ffff800fb4afcb00 [ 208.015295] x23: ffff00007d2f5038 x22: ffff00007d2f5000 [ 208.020599] x21: fffffffffeff2a6f x20: 000000000000000a [ 208.025903] x19: ffff000009578000 x18: 0000000000000a03 [ 208.031206] x17: 0000000000000000 x16: 0000000000000000 [ 208.036510] x15: 0000ffff9de83000 x14: 0000000000000000 [ 208.041813] x13: 0000000000000000 x12: 0000000000000000 [ 208.047116] x11: 0000000000000001 x10: ffff0000089e7f18 [ 208.052419] x9 : fffffffffeff2a6f x8 : 0000000000000000 [ 208.057723] x7 : 000000000000000a x6 : 00280c6160000000 [ 208.063026] x5 : 0000000000000018 x4 : 0000000000007db6 [ 208.068329] x3 : 000000000008647a x2 : 19868179b1484500 [ 208.073632] x1 : 0000000000000000 x0 : ffff000009578c08 [ 208.078938] Process test_verifier (pid: 2256, stack limit = 0x0000000049ca7974) [ 208.086235] Call trace: [ 208.088672] bpf_skb_load_helper_8_no_cache+0x34/0xc0 [ 208.093713] 0xffff000000bdb754 [ 208.096845] bpf_test_run+0x78/0xf8 [ 208.100324] bpf_prog_test_run_skb+0x148/0x230 [ 208.104758] sys_bpf+0x314/0x1198 [ 208.108064] el0_svc_naked+0x30/0x34 [ 208.111632] Code: 91302260 f9400001 f9001fa1 d2800001 (29500680) [ 208.117717] ---[ end trace 263cb8a59b5bf29f ]--- The program itself which caused this had a long jump over the whole instruction sequence where all of the inner instructions required heavy expansions into multiple BPF instructions. Additionally, I also had BPF hardening enabled which requires once more rewrites of all constant values in order to blind them. Each time we rewrite insns, bpf_adj_branches() would need to potentially adjust branch targets which cross the patchlet boundary to accommodate for the additional delta. Eventually that lead to the case where the target offset could not fit into insn->off's upper 0x7fff limit anymore where then offset wraps around becoming negative (in s16 universe), or vice versa depending on the jump direction. Therefore it becomes necessary to detect and reject any such occasions in a generic way for native eBPF and cBPF to eBPF migrations. For the latter we can simply check bounds in the bpf_convert_filter()'s BPF_EMIT_JMP helper macro and bail out once we surpass limits. The bpf_patch_insn_single() for native eBPF (and cBPF to eBPF in case of subsequent hardening) is a bit more complex in that we need to detect such truncations before hitting the bpf_prog_realloc(). Thus the latter is split into an extra pass to probe problematic offsets on the original program in order to fail early. With that in place and carefully tested I no longer hit the panic and the rewrites are rejected properly. The above example panic I've seen on bpf-next, though the issue itself is generic in that a guard against this issue in bpf seems more appropriate in this case.

[PATCH 0/2] net: ipa: back-port concurrent replenish fix

by Alex Elder

Attached are two patches that take the place of one IPA fix that was requested for back-port. The original did not apply cleanly, so one prerequisite was back-ported, followed by the "real" fix. They are built upon Linux v5.10.95. I wasn't sure how I was supposed to indicate this was a manual back-port. I added the upstream commit ID in each patch but it needs to be edited. And I added a "References" tag indicating the e-mail to which this small series responds. Please let me know if there's something else/more I should do. Thanks. -Alex Alex Elder (2): net: ipa: use a bitmap for endpoint replenish_enabled net: ipa: prevent concurrent replenish drivers/net/ipa/ipa_endpoint.c | 20 ++++++++++++++++---- drivers/net/ipa/ipa_endpoint.h | 15 ++++++++++++++- 2 files changed, 30 insertions(+), 5 deletions(-) -- 2.32.0

[PATCH 1/1] net: ipa: fix atomic update in ipa_endpoint_replenish()

by Alex Elder

XXX commit 6c0e3b5ce94947b311348c367db9e11dcb2ccc93 upstream. In ipa_endpoint_replenish(), if an error occurs when attempting to replenish a receive buffer, we just quit and try again later. In that case we increment the backlog count to reflect that the attempt was unsuccessful. Then, if the add_one flag was true we increment the backlog again. This second increment is not included in the backlog local variable though, and its value determines whether delayed work should be scheduled. This is a bug. Fix this by determining whether 1 or 2 should be added to the backlog before adding it in a atomic_add_return() call.
