2017-02-18i40e: refactor AQ CMD buffer debug printingAlan Brady2-14/+24
This patch refactors the '%*ph' printk format specifier to instead use the print_hex_dump function, as recommended by the '%*ph' documentation. This produces better/more standardized output.

2017-02-18i40e: Fix Adaptive ITR enablingCarolyn Wyborny2-12/+12
This patch fixes a bug introduced with the addition of the per queue ITR feature support in ethtool. With that addition, there were functions added which converted the ITR settings to binary values. The IS_ENABLED macros that run on those values check whether a bit is set or not and with the value being binary, the bit check always returned ITR disabled which prevents any updating of the ITR rate. This patch fixes the problem by changing the functions to return the current ITR value instead and renaming it to better reflect its function. These functions now provide a value which will be accurately asessed and update the ITR as intended.

2017-02-18i40evf: free rings in remove functionMitch Williams1-1/+2
When the i40evf_remove() calls netdev close, the device doesn't actually close - it schedules the work for the watchdog to perform. Since we're stopping the watchdog, this work doesn't get done. However, we're resetting the part, so we can free resources after the reset request has gone through. This plugs a memory leak.

In i40e_link_event, we set hw->phy.get_link_info to true just prior to calling i40e_get_link_status, which conveniently runs i40e_update_link_info for us.

2017-02-18i40e: enable mc magic pkt wakeup during power downJoshua Hay3-10/+67
This patch adds a call to the mac_address_write admin q function during power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit thus enabling multicast magic packet wakeup. A FW workaround is needed to write the multicast magic wake up enable bit in the PRTPM_SAH register. The FW expects the mac address write admin q cmd to be called first with one of the WRITE_TYPE_LAA flags and then with the multicast relevant flags. *Note: This solution only works for X722 devices currently. A PFR will clear the previously mentioned bit by default, but X722 has support for a WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once other devices support this flag, this solution should work as well.

2017-02-18i40e: fix disable overflow promiscuous modeAlan Brady1-5/+7
There exists a bug in which the driver is unable to exit overflow promiscuous mode after having added "too many" mac filters. It is expected that after triggering overflow promiscuous, removing the failed/extra filters should then disable overflow promiscuous mode. The bug exists because we were intentionally skipping the sync_vsi_filter path in cases where we were removing failed filters since they shouldn't have been added to the firmware in the first place, however we still need to go through the sync_vsi_filter code path to determine whether or not it is ok to exit overflow promiscuous mode. This patch fixes the bug by making sure we go through the sync_vsi_filter path in cases of failed filters.

2017-02-17sfc: fix filter_id misinterpretation in edge caseJon Cooper1-18/+30
On EF10, hardware filter IDs are 13 bits, but in some places we store 32-bit "full filter IDs" in which higher order bits encode the filter match-priority. This could cause a filter to have a full filter ID of 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use in 16-bit "short" filter IDs (without match-priority bits). This would occur if the hardware filter ID was 0x1fff and the match-priority was 7. Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can be called on full filter IDs, and will WARN_ON if this ever happens. So, since we have plenty of spare bits in the full filter ID, this patch shifts the priority bits left one bit when constructing the full filter IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID. This patch also replaces open-coded full<->short filter ID conversions with calls to functions, thus keeping the definition of the full filter ID format in one place.

2017-02-17vmxnet3: prevent building with 64K pagesArnd Bergmann1-0/+3
I got a warning about broken code on ARM64 with 64K pages: drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init': drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow] rq->buf_info[0][i].len = PAGE_SIZE; 'len' here is a 16-bit integer, so this clearly won't work. I don't think this driver is used much on anything other than x86, so there is no need to fix this properly and we can work around it with a Kconfig dependency to forbid known-broken configurations. qemu in theory supports it on other architectures too, but presumably only for compatibility with x86 guests that also run on vmware.

2017-02-17rtnl: don't account unused struct ifla_port_vsi in rtnl_port_sizeDaniel Borkmann1-4/+7
When allocating rtnl dump messages, struct ifla_port_vsi is never dumped, so we can save header plus payload in rtnl_port_size(). Infact, attribute IFLA_PORT_VSI_TYPE and struct ifla_port_vsi are not used anywhere in the kernel. We only need to keep the nla policy should applications in user space be filling this out. Same NLA_BINARY issue exists as was fixed in 364d5716a7ad ("rtnetlink: ifla_vf_policy: fix misuses of NLA_BINARY") and others, but then again IFLA_PORT_VSI_TYPE is not used anywhere, so just add a comment that it's unused.

2017-02-17bpf: make jited programs visible in tracesDaniel Borkmann13-63/+419
Long standing issue with JITed programs is that stack traces from function tracing check whether a given address is kernel code through {__,}kernel_text_address(), which checks for code in core kernel, modules and dynamically allocated ftrace trampolines. But what is still missing is BPF JITed programs (interpreted programs are not an issue as __bpf_prog_run() will be attributed to them), thus when a stack trace is triggered, the code walking the stack won't see any of the JITed ones. The same for address correlation done from user space via reading /proc/kallsyms. This is read by tools like perf, but the latter is also useful for permanent live tracing with eBPF itself in combination with stack maps when other eBPF types are part of the callchain. See offwaketime example on dumping stack from a map. This work tries to tackle that issue by making the addresses and symbols known to the kernel. The lookup from *kernel_text_address() is implemented through a latched RB tree that can be read under RCU in fast-path that is also shared for symbol/size/offset lookup for a specific given address in kallsyms. The slow-path iteration through all symbols in the seq file done via RCU list, which holds a tiny fraction of all exported ksyms, usually below 0.1 percent. Function symbols are exported as bpf_prog_<tag>, in order to aide debugging and attribution. This facility is currently enabled for root-only when bpf_jit_kallsyms is set to 1, and disabled if hardening is active in any mode. The rationale behind this is that still a lot of systems ship with world read permissions on kallsyms thus addresses should not get suddenly exposed for them. If that situation gets much better in future, we always have the option to change the default on this. Likewise, unprivileged programs are not allowed to add entries there either, but that is less of a concern as most such programs types relevant in this context are for root-only anyway. If enabled, call graphs and stack traces will then show a correct attribution; one example is illustrated below, where the trace is now visible in tooling such as perf script --kallsyms=/proc/kallsyms and friends.

2017-02-17rhashtable: Add nested tablesHerbert Xu2-72/+276
This patch adds code that handles GFP_ATOMIC kmalloc failure on insertion. As we cannot use vmalloc, we solve it by making our hash table nested. That is, we allocate single pages at each level and reach our desired table size by nesting them. When a nested table is created, only a single page is allocated at the top-level. Lower levels are allocated on demand during insertion. Therefore for each insertion to succeed, only two (non-consecutive) pages are needed. After a nested table is created, a rehash will be scheduled in order to switch to a vmalloced table as soon as possible. Also, the rehash code will never rehash into a nested table. If we detect a nested table during a rehash, the rehash will be aborted and a new rehash will be scheduled. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2017-02-17net/sched: Reflect HW offload statusOr Gerlitz2-2/+9
Currently there is no way of querying whether a filter is offloaded to HW or not when using "both" policy (where none of skip_sw or skip_hw flags are set by user-space). Add two new flags, "in hw" and "not in hw" such that user space can determine if a filter is actually offloaded to hw or not. The "in hw" UAPI semantics was chosen so it's similar to the "skip hw" flag logic. If none of these two flags are set, this signals running over older kernel.

2017-02-17ptp: create "pins" together with the rest of attributesDmitry Torokhov3-42/+24
Let's switch to using device_create_with_groups(), which will allow us to create "pins" attribute group together with the rest of ptp device attributes, and before userspace gets notified about ptp device creation.

2017-02-17ptp: use is_visible method to hide unused attributesDmitry Torokhov1-70/+55
Instead of creating selected attributes after the device is created (and after userspace potentially seen uevent), lets use attribute group is_visible() method to control which attributes are shown. This will allow us to create all attributes (except "pins" group, which will be taken care of later) before userspace gets notified about new ptp class device.

2017-02-17mlx4: do not fire tasklet unless necessaryEric Dumazet2-9/+6
All rx and rx netdev interrupts are handled by respectively by mlx4_en_rx_irq() and mlx4_en_tx_irq() which simply schedule a NAPI. But mlx4_eq_int() also fires a tasklet to service all items that were queued via mlx4_add_cq_to_tasklet(), but this handler was not called unless user cqe was handled. This is very confusing, as "mpstat -I SCPU ..." show huge number of tasklet invocations. This patch saves this overhead, by carefully firing the tasklet directly from mlx4_add_cq_to_tasklet(), removing four atomic operations per IRQ.
