2017-11-14net: mvneta: fix handling of the Tx descriptor counterSimon Guinot
The mvneta controller provides a 8-bit register to update the pending Tx descriptor counter. Then, a maximum of 255 Tx descriptors can be added at once. In the current code the mvneta_txq_pend_desc_add function assumes the caller takes care of this limit. But it is not the case. In some situations (xmit_more flag), more than 255 descriptors are added. When this happens, the Tx descriptor counter register is updated with a wrong value, which breaks the whole Tx queue management. This patch fixes the issue by allowing the mvneta_txq_pend_desc_add function to process more than 255 Tx descriptors.

After commit b94d22d94ad22 "ARM64: dts: meson-gx: add external PHY interrupt on some platforms" ethernet stopped working on my Odroid-C2 which has a RTL8211F phy. It turned out that no interrupts were triggered. Further analysis showed the register INER can't be altered on page 0. Because register INSR needs to be accessed via page 0xa43 I assumed that register INER needs to be accessed via some page too. Some brute force check resulted in page 0xa42 being the right one. With this patch the phy is working properly in interrupt mode.

Rasmus Villemoes says: ==================== net: core: devname allocation cleanups It's somewhat confusing to have both dev_alloc_name and dev_get_valid_name. I can't see why the former is less strict than the latter, so make them (or rather dev_alloc_name_ns and dev_get_valid_name) equivalent, hardening dev_alloc_name() a little. Obvious follow-up patches would be to only export one function, and make dev_alloc_name a static inline wrapper for that (whichever name is chosen for the exported interface). But maybe there is a good reason the two exported interfaces do different checking, so I'll refrain from including the trivial but tree-wide renaming in this series. ==================== Signed-off-by: David S.

2017-11-14net: core: improve sanity checking in __dev_alloc_nameRasmus Villemoes
__dev_alloc_name is called from the public (and exported) dev_alloc_name(), so we don't have a guarantee that strlen(name) is at most IFNAMSIZ. If somebody manages to get __dev_alloc_name called with a % char beyond the 31st character, we'd be making a snprintf() call that will very easily crash the kernel (using an appropriate %p extension, we'll likely dereference some completely bogus pointer). In the normal case where strlen() is sane, we don't even save anything by limiting to IFNAMSIZ, so just use strchr().

2017-11-14bpf: improve verifier ARG_CONST_SIZE_OR_ZERO semanticsYonghong Song
For helpers, the argument type ARG_CONST_SIZE_OR_ZERO permits the access size to be 0 when accessing the previous argument (arg). Right now, it requires the arg needs to be NULL when size passed is 0 or could be 0. It also requires a non-NULL arg when the size is proved to be non-0. This patch changes verifier ARG_CONST_SIZE_OR_ZERO behavior such that for size-0 or possible size-0, it is not required the arg equal to NULL. There are a couple of reasons for this semantics change, and all of them intends to simplify user bpf programs which may improve user experience and/or increase chances of verifier acceptance. Together with the next patch which changes bpf_probe_read arg2 type from ARG_CONST_SIZE to ARG_CONST_SIZE_OR_ZERO, the following two examples, which fail the verifier currently, are able to get verifier acceptance. Example 1: unsigned long len = pend - pstart; len = len > MAX_PAYLOAD_LEN ? MAX_PAYLOAD_LEN : len; len &= MAX_PAYLOAD_LEN; bpf_probe_read(data->payload, len, pstart); It does not have test for "len > 0" and it failed the verifier. Users may not be aware that they have to add this test. Converting the bpf_probe_read helper to have ARG_CONST_SIZE_OR_ZERO helps the above code get verifier acceptance. Example 2: Here is one example where llvm "messed up" the code and the verifier fails. ...... unsigned long len = pend - pstart; if (len > 0 && len <= MAX_PAYLOAD_LEN) bpf_probe_read(data->payload, len, pstart); ...... The compiler generates the following code and verifier fails: ...... 39: (79) r2 = *(u64 *)(r10 -16) 40: (1f) r2 -= r8 41: (bf) r1 = r2 42: (07) r1 += -1 43: (25) if r1 > 0xffe goto pc+3 R0=inv(id=0) R1=inv(id=0,umax_value=4094,var_off=(0x0; 0xfff)) R2=inv(id=0) R6=map_value(id=0,off=0,ks=4,vs=4095,imm=0) R7=inv(id=0) R8=inv(id=0) R9=inv0 R10=fp0 44: (bf) r1 = r6 45: (bf) r3 = r8 46: (85) call bpf_probe_read#45 R2 min value is negative, either use unsigned or 'var &= const' ...... The compiler optimization is correct. If r1 = 0, r1 - 1 = 0xffffffffffffffff > 0xffe. If r1 != 0, r1 - 1 will not wrap. r1 > 0xffe at insn #43 can actually capture both "r1 > 0" and "len <= MAX_PAYLOAD_LEN". This however causes an issue in verifier as the value range of arg2 "r2" does not properly get refined and lead to verification failure. Relaxing bpf_prog_read arg2 from ARG_CONST_SIZE to ARG_CONST_SIZE_OR_ZERO allows the following simplied code: unsigned long len = pend - pstart; if (len <= MAX_PAYLOAD_LEN) bpf_probe_read(data->payload, len, pstart); The llvm compiler will generate less complex code and the verifier is able to verify that the program is okay.

2017-11-14tcp: allow drivers to tweak TSQ logicEric Dumazet
I had many reports that TSQ logic breaks wifi aggregation. Current logic is to allow up to 1 ms of bytes to be queued into qdisc and drivers queues. But Wifi aggregation needs a bigger budget to allow bigger rates to be discovered by various TCP Congestion Controls algorithms. This patch adds an extra socket field, allowing wifi drivers to select another log scale to derive TCP Small Queue credit from current pacing rate. Initial value is 10, meaning that this patch does not change current behavior. We expect wifi drivers to set this field to smaller values (tests have been done with values from 6 to 9) They would have to use following template : if (skb->sk && skb->sk->sk_pacing_shift != MY_PACING_SHIFT) skb->sk->sk_pacing_shift = MY_PACING_SHIFT; Ref: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1670041 Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Johannes Berg <johannes.berg@intel.com> Cc: Toke Høiland-Jørgensen <toke@toke.dk> Cc: Kir Kolyshkin <kir@openvz.org> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.
