The main flaw was the simplification of the use of multiple tracers having the same filter (like function and function_graph, that use the set_ftrace_filter file to filter their code). The design assumed that the two tracers could never run simultaneously as only one tracer can be used at a time. The problem with this assumption was that the function profiler could be implemented on top of the function graph tracer, and the function profiler could run at the same time as the function tracer. This caused the assumption to be broken and when ftrace detected this failed assumpiton it would spit out a nasty warning and shut itself down. Instead of using a single ftrace_ops that switches between the function and function_graph callbacks, the two tracers can again use their own ftrace_ops. But instead of having a complex hierarchy of ftrace_ops, the filter fields are placed in its own structure and the ftrace_ops can carefully use the same filter. This change took a bit to be able to allow for this and currently only the global_ops can share the same filter, but this new design can easily be modified to allow for any ftrace_ops to share its filter with another ftrace_ops. The first four patches deal with the change of allowing the ftrace_ops to share the filter (and this needs to go to 3.16 as well). The fifth patch fixes a bug that was also caused by the new changes but only for archs other than x86, and only if those archs implement a direct call to the function_graph tracer which they do not do yet but will in the future. It does not need to go to stable, but needs to be fixed before the other archs update their code to allow direct calls to the function_graph trampoline" * tag 'trace-fixes-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Use current addr when converting to nop in __ftrace_replace_code() ftrace: Fix function_profiler and function tracer together ftrace: Fix up trampoline accounting with looping on hash ops ftrace: Update all ftrace_ops for a ftrace_hash_ops update ftrace: Allow ftrace_ops to use the hashes from other ops 25 August 2014, 22:11:53 UTC

d856f32 Benjamin LaHaise 24 August 2014, 17:14:05 UTC aio: fix reqs_available handling As reported by Dan Aloni, commit f8567a3845ac ("aio: fix aio request leak when events are reaped by userspace") introduces a regression when user code attempts to perform io_submit() with more events than are available in the ring buffer. Reverting that commit would reintroduce a regression when user space event reaping is used. Fixing this bug is a bit more involved than the previous attempts to fix this regression. Since we do not have a single point at which we can count events as being reaped by user space and io_getevents(), we have to track event completion by looking at the number of events left in the event ring. So long as there are as many events in the ring buffer as there have been completion events generate, we cannot call put_reqs_available(). The code to check for this is now placed in refill_reqs_available(). A test program from Dan and modified by me for verifying this bug is available at http://www.kvack.org/~bcrl/20140824-aio_bug.c .

39b5552 Steven Rostedt (Red Hat) 18 August 2014, 00:59:10 UTC ftrace: Use current addr when converting to nop in __ftrace_replace_code() In __ftrace_replace_code(), when converting the call to a nop in a function it needs to compare against the "curr" (current) value of the ftrace ops, and not the "new" one. It currently does not affect x86 which is the only arch to do the trampolines with function graph tracer, but when other archs that do depend on this code implement the function graph trampoline, it can crash.

5f151b2 Steven Rostedt (Red Hat) 15 August 2014, 21:18:46 UTC ftrace: Fix function_profiler and function tracer together The latest rewrite of ftrace removed the separate ftrace_ops of the function tracer and the function graph tracer and had them share the same ftrace_ops. This simplified the accounting by removing the multiple layers of functions called, where the global_ops func would call a special list that would iterate over the other ops that were registered within it (like function and function graph), which itself was registered to the ftrace ops list of all functions currently active. If that sounds confusing, the code that implemented it was also confusing and its removal is a good thing. The problem with this change was that it assumed that the function and function graph tracer can never be used at the same time. This is mostly true, but there is an exception. That is when the function profiler uses the function graph tracer to profile. The function profiler can be activated the same time as the function tracer, and this breaks the assumption and the result is that ftrace will crash (it detects the error and shuts itself down, it does not cause a kernel oops). To solve this issue, a previous change allowed the hash tables for the functions traced by a ftrace_ops to be a pointer and let multiple ftrace_ops share the same hash. This allows the function and function_graph tracer to have separate ftrace_ops, but still share the hash, which is what is done. Now the function and function graph tracers have separate ftrace_ops again, and the function tracer can be run while the function_profile is active.

It turns out that callers of this interface can map adjacent requests (by file position as seen by req_offset + req->wb_bytes) to different pages, even when they could share a page. An example is the direct I/O interface - iov_iter_get_pages_alloc may return one segment with a partial page filled and the next segment (which is adjacent in the file position) starts with a new page.

This avoids overruning the page vector - it is sized based on how many bytes there are, not by request count.

This also adds bounds checking to the page vector with a graceful failure (WARN_ON_ONCE and pgio error returned to application).

bce0b6c Steven Rostedt (Red Hat) 21 August 2014, 03:57:04 UTC ftrace: Fix up trampoline accounting with looping on hash ops Now that a ftrace_hash can be shared by multiple ftrace_ops, they can dec the rec->flags by more than once (one per those that share the ftrace_hash). This means that the tramp_hash may not have a hash item when it was added. For example, if two ftrace_ops share a hash for a ftrace record, and the first ops has a trampoline, when it adds itself it will set the rec->flags TRAMP flag and increments its nr_trampolines counter. When the second ops is added, it must clear that tramp flag but also decrement the other ops that shares its hash. As the update to the function callbacks has not yet been performed, the other ops will not have the tramp hash set yet and it can not be used to know to decrement its nr_trampolines. Luckily, the tramp_hash does not need to be used. As the ftrace_mutex is held, a ops with a trampoline to a record during an update of another ops that shares the record will have its func_hash pointing to it. Since a trampoline can only be set for a record if only one ops is attached to it, we can just check if the record has a trampoline (the FTRACE_FL_TRAMP flag is set) and then find the ops that has this record in its hashes. Also added some output to help debug when things go wrong.

aa4a83e Daniel Borkmann 22 August 2014, 11:03:30 UTC net: sctp: fix suboptimal edge-case on non-active active/retrans path selection In SCTP, selection of active (T.ACT) and retransmission (T.RET) transports is being done whenever transport control operations (UP, DOWN, PF, ...) are engaged through sctp_assoc_control_transport(). Commits 4c47af4d5eb2 ("net: sctp: rework multihoming retransmission path selection to rfc4960") and a7288c4dd509 ("net: sctp: improve sctp_select_active_and_retran_path selection") have both improved it towards a more fine-grained and optimal path selection. Currently, the selection algorithm for T.ACT and T.RET is as follows: 1) Elect the two most recently used ACTIVE transports T1, T2 for T.ACT, T.RET, where T.ACT<-T1 and T1 is most recently used 2) In case primary path T.PRI not in {T1, T2} but ACTIVE, set T.ACT<-T.PRI and T.RET<-T1 3) If only T1 is ACTIVE from the set, set T.ACT<-T1 and T.RET<-T1 4) If none is ACTIVE, set T.ACT<-best(T.PRI, T.RET, T3) where T3 is the most recently used (if avail) in PF, set T.RET<-T.PRI Prior to above commits, 4) was simply a camp on T.ACT<-T.PRI and T.RET<-T.PRI, ignoring possible paths in PF. Camping on T.PRI is still slightly suboptimal as it can lead to the following scenario: Setup: <A> <B> T1: p1p1 (10.0.10.10) <==> .'`) <==> p1p1 (10.0.10.12) <= T.PRI T2: p1p2 (10.0.10.20) <==> (_ . ) <==> p1p2 (10.0.10.22) net.sctp.rto_min = 1000 net.sctp.path_max_retrans = 2 net.sctp.pf_retrans = 0 net.sctp.hb_interval = 1000 T.PRI is permanently down, T2 is put briefly into PF state (e.g. due to link flapping). Here, the first time transmission is sent over PF path T2 as it's the only non-INACTIVE path, but the retransmitted data-chunks are sent over the INACTIVE path T1 (T.PRI), which is not good. After the patch, it's choosing better transports in both cases by modifying step 4): 4) If none is ACTIVE, set T.ACT_new<-best(T.ACT_old, T3) where T3 is the most recently used (if avail) in PF, set T.RET<-T.ACT_new This will still select a best possible path in PF if available (which can also include T.PRI/T.RET), and set both T.ACT/T.RET to it. In case sctp_assoc_control_transport() *just* put T.ACT_old into INACTIVE as it transitioned from ACTIVE->PF->INACTIVE and stays in INACTIVE just for a very short while before going back ACTIVE, it will guarantee that this path will be reselected for T.ACT/T.RET since T3 (PF) is not available. Previously, this was not possible, as we would only select between T.PRI and T.RET, and a possible T3 would be NULL due to the fact that we have just transitioned T3 in sctp_assoc_control_transport() from PF->INACTIVE and would select a suboptimal path when T.PRI/T.RET have worse properties. In the case that T.ACT_old permanently went to INACTIVE during this transition and there's no PF path available, plus T.PRI and T.RET are INACTIVE as well, we would now camp on T.ACT_old, but if everything is being INACTIVE there's really not much we can do except hoping for a successful HB to bring one of the transports back up again and, thus cause a new selection through sctp_assoc_control_transport(). Now both tests work fine: Case 1: 1. T1 S(ACTIVE) T.ACT T2 S(ACTIVE) T.RET 2. T1 S(ACTIVE) T.ACT, T.RET T2 S(PF) 3. T1 S(ACTIVE) T.ACT, T.RET T2 S(INACTIVE) 5. T1 S(PF) T.ACT, T.RET T2 S(INACTIVE) [ 5.1 T1 S(INACTIVE) T.ACT, T.RET T2 S(INACTIVE) ] 6. T1 S(ACTIVE) T.ACT, T.RET T2 S(INACTIVE) 7. T1 S(ACTIVE) T.ACT T2 S(ACTIVE) T.RET Case 2: 1. T1 S(ACTIVE) T.ACT T2 S(ACTIVE) T.RET 2. T1 S(PF) T2 S(ACTIVE) T.ACT, T.RET 3. T1 S(INACTIVE) T2 S(ACTIVE) T.ACT, T.RET 5. T1 S(INACTIVE) T2 S(PF) T.ACT, T.RET [ 5.1 T1 S(INACTIVE) T2 S(INACTIVE) T.ACT, T.RET ] 6. T1 S(INACTIVE) T2 S(ACTIVE) T.ACT, T.RET 7.

Anything in the skb beyond the VLAN TPID may be still non-linear, including the inner TCI and ethertype. While ovs_flow_extract takes care of IP and IPv6 headers, it does nothing with ETH_P_8021Q. Later, if OVS_ACTION_ATTR_POP_VLAN is executed, __pop_vlan_tci pulls the next vlan header into vlan_tci. This leads to two things: 1. Part of the resulting ethernet header is in the non-linear part of the skb. When eth_type_trans is called later as the result of OVS_ACTION_ATTR_OUTPUT, kernel BUGs in __skb_pull. Also, __pop_vlan_tci is in fact accessing random data when it reads past the TPID. 2. network_header points into the ethernet header instead of behind it. mac_len is set to a wrong value (10), too.

The root cause is that ptp uses a periodic timer to access enet register even if ipg clock is disabled. FEC ptp driver start one period timer to read 1588 counter register in the ptp init function that is called after FEC driver is probed. To save power, after FEC probe finish, FEC driver disable all clocks including ipg clock that is needed for register access. i.MX5x, i.MX6q/dl/sl FEC register access don't cause system hang when ipg clock is disabled, just return zero value. But for i.MX6sx SOC, it cause system hang. To avoid the issue, we need to check ptp clock status before ptp timer count access.

33b7f99 Steven Rostedt (Red Hat) 15 August 2014, 21:23:02 UTC ftrace: Allow ftrace_ops to use the hashes from other ops Currently the top level debug file system function tracer shares its ftrace_ops with the function graph tracer. This was thought to be fine because the tracers are not used together, as one can only enable function or function_graph tracer in the current_tracer file. But that assumption proved to be incorrect. The function profiler can use the function graph tracer when function tracing is enabled. Since all function graph users uses the function tracing ftrace_ops this causes a conflict and when a user enables both function profiling as well as the function tracer it will crash ftrace and disable it. The quick solution so far is to move them as separate ftrace_ops like it was earlier. The problem though is to synchronize the functions that are traced because both function and function_graph tracer are limited by the selections made in the set_ftrace_filter and set_ftrace_notrace files. To handle this, a new structure is made called ftrace_ops_hash. This structure will now hold the filter_hash and notrace_hash, and the ftrace_ops will point to this structure. That will allow two ftrace_ops to share the same hashes. Since most ftrace_ops do not share the hashes, and to keep allocation simple, the ftrace_ops structure will include both a pointer to the ftrace_ops_hash called func_hash, as well as the structure itself, called local_hash. When the ops are registered, the func_hash pointer will be initialized to point to the local_hash within the ftrace_ops structure. Some of the ftrace internal ftrace_ops will be initialized statically. This will allow for the function and function_graph tracer to have separate ops but still share the same hash tables that determine what functions they trace.

7c3afd8 Yuval Mintz 18 August 2014, 19:36:23 UTC bnx2x: Revert UNDI flushing mechanism Commit 91ebb929b6f8 ("bnx2x: Add support for Multi-Function UNDI") [which was later supposedly fixed by de682941eef3 ("bnx2x: Fix UNDI driver unload")] introduced a bug in which in some [yet-to-be-determined] scenarios the alternative flushing mechanism which was to guarantee the Rx buffers are empty before resetting them during device probe will fail. If this happens, when device will be loaded once more a fatal attention will occur; Since this most likely happens in boot from SAN scenarios, the machine will fail to load. Notice this may occur not only in the 'Multi-Function' scenario but in the regular scenario as well, i.e., this introduced a regression in the driver's ability to perform boot from SAN. The patch reverts the mechanism and applies the old scheme to multi-function devices as well as to single-function devices.

As a result, if a guest using macvtap wants to receive multicast traffic, it has to set IFF_ALLMULTI or IFF_PROMISC. This patch makes it possible to use the fdb interface to add multicast addresses to the filter thus allowing a guest to receive only targeted multicast traffic.

b3f2078 Pawel Moll 13 June 2014, 15:03:32 UTC perf: Handle compat ioctl When running a 32-bit userspace on a 64-bit kernel (eg. i386 application on x86_64 kernel or 32-bit arm userspace on arm64 kernel) some of the perf ioctls must be treated with special care, as they have a pointer size encoded in the command. For example, PERF_EVENT_IOC_ID in 32-bit world will be encoded as 0x80042407, but 64-bit kernel will expect 0x80082407. In result the ioctl will fail returning -ENOTTY. This patch solves the problem by adding code fixing up the size as compat_ioctl file operation.

95d516b Daniel Drake 16 July 2014, 08:50:06 UTC ARM: dts: ODROID i2c improvements Increase max i2c bus frequency beyond the default for faster data transfers. According to the manual, these faster speeds are only available when the board is wired up the right way. In this case, the vendor kernel has run at this speed for a long time. sda-delay is needed for talking to RTC on PMIC, otherwise the i2c controller never sees an ACK. Strangely the other PMIC i2c slave (the main one) works fine even without this delay. I Chose value 100 to match the vendor kernel.
