2022-05-21perf session: Fix Intel LBR callstack entries and nr print messageChengdong Li
When generating callstack information from branch_stack(Intel LBR), the actual number of callstack entry should be bigger than the number of branch_stack, for example: branch_stack records: B() -> C() A() -> B() converted callstack records should be: C() B() A() though, the number of callstack equals to the number of branch stack plus 1. This patch fixes above issue in branch_stack__printf(). For example, # echo 'scale=2000; 4*a(1)' > cmd # perf record --call-graph lbr bc -l < cmd Before applying this patch, `perf script -D` output: 1220022677386876 0x2a40 [0xd8]: PERF_RECORD_SAMPLE(IP, 0x4002): 17990/17990: 0x40a6d6 period: 894172 addr: 0 ...

2022-05-21perf test bpf: Skip test if clang is not presentAthira Rajeev
Perf BPF filter test fails in environment where "clang" is not installed. Test failure logs: <<>> 42: BPF filter : 42.1: Basic BPF filtering : Skip 42.2: BPF pinning : FAILED! 42.3: BPF prologue generation : FAILED! <<>> Enabling verbose option provided debug logs which says clang/llvm needs to be installed. Snippet of verbose logs: <<>> 42.2: BPF pinning : --- start --- test child forked, pid 61423 ERROR: unable to find clang. Hint: Try to install latest clang/llvm to support BPF. Check your $PATH <<logs_here>> Failed to compile test case: 'Basic BPF llvm compile' Unable to get BPF object, fix kbuild first test child finished with -1 ---- end ---- BPF filter subtest 2: FAILED! <<>> Here subtests, "BPF pinning" and "BPF prologue generation" failed and logs shows clang/llvm is needed. After installing clang, testcase passes. Reason on why subtest failure happens though logs has proper debug information: Main function __test__bpf calls test_llvm__fetch_bpf_obj by passing 4th argument as true ( 4th arguments maps to parameter "force" in test_llvm__fetch_bpf_obj ). But this will cause test_llvm__fetch_bpf_obj to skip the check for clang/llvm. Snippet of code part which checks for clang based on parameter "force" in test_llvm__fetch_bpf_obj: <<>> if (!force && (!llvm_param.user_set_param && <<>> Since force is set to "false", test won't get skipped and fails to compile test case. The BPF code compilation needs clang, So pass the fourth argument as "false" and also skip the test if reason for return is "TEST_SKIP" After the patch: <<>> 42: BPF filter : 42.1: Basic BPF filtering : Skip 42.2: BPF pinning : Skip 42.3: BPF prologue generation : Skip <<>> Fixes: ba1fae431e74bb42 ("perf test: Add 'perf test BPF'") Reviewed-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Acked-by: Ian Rogers <irogers@google.com> Cc: Disha Goel <disgoel@linux.vnet.ibm.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: linuxppc-dev@lists.ozlabs.org Cc: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Nageswara R Sastry <rnsastry@linux.ibm.com> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lore.kernel.org/r/20220511115438.84032-1-atrajeev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2022-05-21perf test session topology: Fix test to skip the test in guest environmentAthira Rajeev
The session topology test fails in powerpc pSeries platform. Test logs: <<>> Session topology : FAILED! <<>> This testcases tests cpu topology by checking the core_id and socket_id stored in perf_env from perf session. The data from perf session is compared with the cpu topology information from "/sys/devices/system/cpu/cpuX/topology" like core_id, physical_package_id. In case of virtual environment, detail like physical_package_id is restricted to be exposed. Hence physical_package_id is set to -1. The testcase fails on such platforms since socket_id can't be fetched from topology info. Skip the testcase in powerpc if physical_package_id returns -1.

2022-05-21perf test: Avoid shell test description infinite loopIan Rogers
for_each_shell_test() is already strict in expecting tests to be files and executable. It is sometimes possible when it iterates over all files that it finds one that is executable and lacks a newline character. When this happens the loop never terminates as it doesn't check for EOF. Add the EOF check to make this loop at least bounded by the file size. If the description is returned as NULL then also skip the test.

2022-05-21perf regs x86: Fix arch__intr_reg_mask() for the hybrid platformKan Liang
The X86 specific arch__intr_reg_mask() is to check whether the kernel and hardware can collect XMM registers. But it doesn't work on some hybrid platform. Without the patch on ADL-N: $ perf record -I? available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10 R11 R12 R13 R14 R15 The config of the test event doesn't contain the PMU information. The kernel may fail to initialize it on the correct hybrid PMU and return the wrong non-supported information. Add the PMU information into the config for the hybrid platform. The same register set is supported among different hybrid PMUs. Checking the first available one is good enough.

2022-05-21perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpcAthira Rajeev
"perf all PMU test" picks the input events from "perf list --raw-dump pmu" list and runs "perf stat -e" for each of the event in the list. In case of powerpc, the PowerVM environment supports events from hv_24x7 and hv_gpci PMU which is of example format like below: - hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/ - hv_gpci/event,partition_id=?/ The value for "?" needs to be filled in depending on system and respective event. CPM_ADJUNCT_INST needs have core value and domain value. hv_gpci event needs partition_id. Similarly, there are other events for hv_24x7 and hv_gpci having "?" in event format. Hence skip these events on powerpc platform since values like partition_id, domain is specific to system and event.

2022-05-21Revert "ACPICA: executer/exsystem: Warn about sleeps greater than 10 ms"Rafael J. Wysocki
Commit 6eaf08770ee8 ("ACPICA: executer/exsystem: Warn about sleeps greater than 10 ms") made acpi_ex_system_do_sleep() log a warning for sleep times greater than 10 ms, but such sleep times are used in power management AML because of the PCI specification requirements. This results with logging warnings that cannot really be acted on in any useful way which is annoying and these warnings show up in the logs on many production systems, so revert commit 6eaf08770ee8.

2022-05-21io_uring: cleanup handling of the two task_work listsJens Axboe
Rather than pass in a bool for whether or not this work item needs to go into the priority list or not, provide separate helpers for it. For most use cases, this also then gets rid of the branch for non-priority task work. While at it, rename the prior_task_list to prio_task_list. Prior is a confusing name for it, as it would seem to indicate that this is the previous task_work list. prio makes it clear that this is a priority task_work list.

2022-05-21i2c: ismt: Provide a DMA buffer for Interrupt Cause LoggingMika Westerberg
Before sending a MSI the hardware writes information pertinent to the interrupt cause to a memory location pointed by SMTICL register. This memory holds three double words where the least significant bit tells whether the interrupt cause of master/target/error is valid. The driver does not use this but we need to set it up because otherwise it will perform DMA write to the default address (0) and this will cause an IOMMU fault such as below: DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set To prevent this from happening, provide a proper DMA buffer for this that then gets mapped by the IOMMU accordingly.

2022-05-20Merge branch 'bpf: refine kernel.unprivileged_bpf_disabled behaviour'Alexei Starovoitov
Alan Maguire says: ==================== Unprivileged BPF disabled (kernel.unprivileged_bpf_disabled >= 1) is the default in most cases now; when set, the BPF system call is blocked for users without CAP_BPF/CAP_SYS_ADMIN. In some cases however, it makes sense to split activities between capability-requiring ones - such as program load/attach - and those that might not require capabilities such as reading perf/ringbuf events, reading or updating BPF map configuration etc. One example of this sort of approach is a service that loads a BPF program, and a user-space program that interacts with it. Here - rather than blocking all BPF syscall commands - unprivileged BPF disabled blocks the key object-creating commands (prog load, map load). Discussion has alluded to this idea in the past [1], and Alexei mentioned it was also discussed at LSF/MM/BPF this year. Changes since v3 [2]: - added acks to patch 1 - CI was failing on Ubuntu; I suspect the issue was an old capability.h file which specified CAP_LAST_CAP as < CAP_BPF, leading to the logic disabling all caps not disabling CAP_BPF. Use CAP_BPF as basis for "all caps" bitmap instead as we explicitly define it in cap_helpers.h if not already found in capabilities.h - made global variables arguments to subtests instead (Andrii, patch 2) Changes since v2 [3]: - added acks from Yonghong - clang compilation issue in selftest with bpf_prog_query() (Alexei, patch 2) - disable all capabilities for test (Yonghong, patch 2) - add assertions that size of perf/ringbuf data matches expectations (Yonghong, patch 2) - add map array size definition, remove unneeded whitespace (Yonghong, patch 2) Changes since RFC [4]: - widened scope of commands unprivileged BPF disabled allows (Alexei, patch 1) - removed restrictions on map types for lookup, update, delete (Alexei, patch 1) - removed kernel CONFIG parameter controlling unprivileged bpf disabled change (Alexei, patch 1) - widened test scope to cover most BPF syscall commands, with positive and negative subtests [1] https://lore.kernel.org/bpf/CAADnVQLTBhCTAx1a_nev7CgMZxv1Bb7ecz1AFRin8tHmjPREJA@mail.gmail.com/ [2] https://lore.kernel.org/bpf/1652880861-27373-1-git-send-email-alan.maguire@oracle.com/T/ [3] https://lore.kernel.org/bpf/1652788780-25520-1-git-send-email-alan.maguire@oracle.com/T/#t [4] https://lore.kernel.org/bpf/20220511163604.5kuczj6jx3ec5qv6@MBP-98dd607d3435.dhcp.thefacebook.com/T/#mae65f35a193279e718f37686da636094d69b96ee ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2022-05-20bpf: refine kernel.unprivileged_bpf_disabled behaviourAlan Maguire
With unprivileged BPF disabled, all cmds associated with the BPF syscall are blocked to users without CAP_BPF/CAP_SYS_ADMIN. However there are use cases where we may wish to allow interactions with BPF programs without being able to load and attach them. So for example, a process with required capabilities loads/attaches a BPF program, and a process with less capabilities interacts with it; retrieving perf/ring buffer events, modifying map-specified config etc. With all BPF syscall commands blocked as a result of unprivileged BPF being disabled, this mode of interaction becomes impossible for processes without CAP_BPF. As Alexei notes "The bpf ACL model is the same as traditional file's ACL. The creds and ACLs are checked at open(). Then during file's write/read additional checks might be performed. BPF has such functionality already. Different map_creates have capability checks while map_lookup has: map_get_sys_perms(map, f) & FMODE_CAN_READ. In other words it's enough to gate FD-receiving parts of bpf with unprivileged_bpf_disabled sysctl. The rest is handled by availability of FD and access to files in bpffs." So key fd creation syscall commands BPF_PROG_LOAD and BPF_MAP_CREATE are blocked with unprivileged BPF disabled and no CAP_BPF. And as Alexei notes, map creation with unprivileged BPF disabled off blocks creation of maps aside from array, hash and ringbuf maps. Programs responsible for loading and attaching the BPF program can still control access to its pinned representation by restricting permissions on the pin path, as with normal files.

2022-05-20Merge branch 'add-a-bhash2-table-hashed-by-port-address'Jakub Kicinski
Joanne Koong says: ==================== Add a bhash2 table hashed by port + address This patchset proposes adding a bhash2 table that hashes by port and address. The motivation behind bhash2 is to expedite bind requests in situations where the port has many sockets in its bhash table entry, which makes checking bind conflicts costly especially given that we acquire the table entry spinlock while doing so, which can cause softirq cpu lockups and can prevent new tcp connections. We ran into this problem at Meta where the traffic team binds a large number of IPs to port 443 and the bind() call took a significant amount of time which led to cpu softirq lockups, which caused packet drops and other failures on the machine The patches are as follows: 1/2 - Adds a second bhash table (bhash2) hashed by port and address 2/2 - Adds a test for timing how long an additional bind request takes when the bhash entry is populated When experimentally testing this on a local server for ~24k sockets bound to the port, the results seen were: ipv4: before - 0.002317 seconds with bhash2 - 0.000018 seconds ipv6: before - 0.002431 seconds with bhash2 - 0.000021 seconds ==================== Link: https://lore.kernel.org/r/20220520001834.2247810-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-05-20selftests: Add test for timing a bind request to a port with a populated ↵Joanne Koong
bhash entry This test populates the bhash table for a given port with MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long a bind request on the port takes. When populating the bhash table, we create the sockets and then bind the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT are set). When timing how long a bind on the port takes, we bind on a different address without SO_REUSEPORT set. We do not set SO_REUSEPORT because we are interested in the case where the bind request does not go through the tb->fastreuseport path, which is fragile (eg tb->fastreuseport path does not work if binding with a different uid). To run the test locally, I did: * ulimit -n 65535000 * ip addr add 2001:0db8:0:f101::1 dev eth0 * ./bind_bhash_test 443 Signed-off-by: Joanne Koong <joannelkoong@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-05-20net: Add a second bind table hashed by port and addressJoanne Koong
We currently have one tcp bind table (bhash) which hashes by port number only. In the socket bind path, we check for bind conflicts by traversing the specified port's inet_bind2_bucket while holding the bucket's spinlock (see inet_csk_get_port() and inet_csk_bind_conflict()). In instances where there are tons of sockets hashed to the same port at different addresses, checking for a bind conflict is time-intensive and can cause softirq cpu lockups, as well as stops new tcp connections since __inet_inherit_port() also contests for the spinlock. This patch proposes adding a second bind table, bhash2, that hashes by port and ip address. Searching the bhash2 table leads to significantly faster conflict resolution and less time holding the spinlock.

But, after failure in amt_req_work() it continues sending a request message step with flushed(invalid) relay information and sets SENT_REQUEST. So, a gateway can't be established with a relay.

2022-05-20net: avoid strange behavior with skb_defer_max == 1Jakub Kicinski
When user sets skb_defer_max to 1 the kick threshold is 0 (half of 1). If we increment queue length before the check the kick will never happen, and the skb may get stranded. This is likely harmless but can be avoided by moving the increment after the check. This way skb_defer_max == 1 will always kick. Still a silly config to have, but somehow that feels more correct. While at it drop a comment which seems to be outdated or confusing, and wrap the defer_count write with a WRITE_ONCE() since it's read on the fast path that avoids taking the lock.
