2021-08-23selftests/bpf: Reduce flakyness in timer_mimYucong Sun
This patch extends wait time in timer_mim. As observed in slow CI environment, it is possible to have interrupt/preemption long enough to cause the test to fail, almost 1 failure in 5 runs.

2021-08-23Merge branch 'Refactor cgroup_bpf internals to use more specific attach_type'Alexei Starovoitov
Dave Marchevsky says: ==================== The cgroup_bpf struct has a few arrays (effective, progs, and flags) of size MAX_BPF_ATTACH_TYPE. These are meant to separate progs by their attach type, currently represented by the bpf_attach_type enum. There are some bpf_attach_type values which are not valid attach types for cgroup bpf programs. Programs with these attach types will never be handled by cgroup_bpf_{attach,detach} and thus will never be held in cgroup_bpf structs. Even if such programs did make it into their reserved slot in those arrays, they would never be executed. Accordingly we can migrate to a new internal cgroup_bpf-specific enum for these arrays, saving some bytes per cgroup and making it more obvious which BPF programs belong there. netns_bpf_attach_type is an existing example of this pattern, let's do similar for cgroup_bpf. v1->v2: Address Daniel's comments * Reverse xmas tree ordering for def changes * Helper macro to reduce to_cgroup_bpf_attach_type boilerplate * checkpatch.pl complains: "ERROR: Macros with complex values should be enclosed in parentheses". Found some existing macros (do 'git grep "define case"') which get same complaint. Think it's fine to keep as-is since it's immediately undef'd. * Remove CG_BPF_ prefix from cgroup_bpf_attach_type * Although I agree that the prefix is redundant, the de-prefixed names feel a bit too 'general' given the internal use of the enum. e.g. when someone sees CGROUP_INET6_BIND it's not obvious that it should only be used in certain ways internally. * Don't feel strongly about this, just my thoughts as a noob to the internals. * Rebase onto latest bpf-next/master * No significant conflicts, some small boilerplate adjustments needed to catch up to Andrii's "bpf: Refactor BPF_PROG_RUN_ARRAY family of macros into functions" change ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2021-08-23bpf: Migrate cgroup_bpf to internal cgroup_bpf_attach_type enumDave Marchevsky
Add an enum (cgroup_bpf_attach_type) containing only valid cgroup_bpf attach types and a function to map bpf_attach_type values to the new enum. Inspired by netns_bpf_attach_type. Then, migrate cgroup_bpf to use cgroup_bpf_attach_type wherever possible. Functionality is unchanged as attach_type_to_prog_type switches in bpf/syscall.c were preventing non-cgroup programs from making use of the invalid cgroup_bpf array slots. As a result struct cgroup_bpf uses 504 fewer bytes relative to when its arrays were sized using MAX_BPF_ATTACH_TYPE. bpf_cgroup_storage is notably not migrated as struct bpf_cgroup_storage_key is part of uapi and contains a bpf_attach_type member which is not meant to be opaque. Similarly, bpf_cgroup_link continues to report its bpf_attach_type member to userspace via fdinfo and bpf_link_info. To ease disambiguation, bpf_attach_type variables are renamed from 'type' to 'atype' when changed to cgroup_bpf_attach_type.

The practical problem is that ucount_max provides a limit that applications inside the user namespace can not exceed. Which means in practice that rlimits that have been converted to use the ucount infrastructure were not able to exceend their initial rlimits. Solve this by setting the relevant values of ucount_max to RLIM_INIFINITY. A limit in init_user_ns is pointless so the code should allow the values to grow as large as possible without riscking an underflow or an overflow. As the ltp test case was a bit of a pain I have reproduced the rlimit failure and tested the fix with the following little C program: > #include <stdio.h> > #include <fcntl.h> > #include <sys/stat.h> > #include <mqueue.h> > #include <sys/time.h> > #include <sys/resource.h> > #include <errno.h> > #include <string.h> > #include <stdlib.h> > #include <limits.h> > #include <unistd.h> > > int main(int argc, char **argv) > { > struct mq_attr mq_attr; > struct rlimit rlim; > mqd_t mqd; > int ret; > > ret = getrlimit(RLIMIT_MSGQUEUE, &rlim); > if (ret != 0) { > fprintf(stderr, "getrlimit(RLIMIT_MSGQUEUE) failed: %s\n", strerror(errno)); > exit(EXIT_FAILURE); > } > printf("RLIMIT_MSGQUEUE %lu %lu\n", > rlim.rlim_cur, rlim.rlim_max); > rlim.rlim_cur = RLIM_INFINITY; > rlim.rlim_max = RLIM_INFINITY; > ret = setrlimit(RLIMIT_MSGQUEUE, &rlim); > if (ret != 0) { > fprintf(stderr, "setrlimit(RLIMIT_MSGQUEUE, RLIM_INFINITY) failed: %s\n", strerror(errno)); > exit(EXIT_FAILURE); > } > > memset(&mq_attr, 0, sizeof(struct mq_attr)); > mq_attr.mq_maxmsg = 65536 - 1; > mq_attr.mq_msgsize = 16*1024*1024 - 1; > > mqd = mq_open("/mq_rlimit_test", O_RDONLY|O_CREAT, 0600, &mq_attr); > if (mqd == (mqd_t)-1) { > fprintf(stderr, "mq_open failed: %s\n", strerror(errno)); > exit(EXIT_FAILURE); > } > ret = mq_close(mqd); > if (ret) { > fprintf(stderr, "mq_close failed; %s\n", strerror(errno)); > exit(EXIT_FAILURE); > } > > return EXIT_SUCCESS; > } Fixes: 6e52a9f0532f ("Reimplement RLIMIT_MSGQUEUE on top of ucounts") Fixes: d7c9e99aee48 ("Reimplement RLIMIT_MEMLOCK on top of ucounts") Fixes: d64696905554 ("Reimplement RLIMIT_SIGPENDING on top of ucounts") Fixes: 21d1c5e386bc ("Reimplement RLIMIT_NPROC on top of ucounts") Reported-by: kernel test robot lkp@intel.com Acked-by: Alexey Gladkov <legion@kernel.org> Link: https://lkml.kernel.org/r/87eeajswfc.fsf_-_@disp2133 Signed-off-by: "Eric W.

2021-08-23bpf: Fix ringbuf helper function compatibilityDaniel Borkmann
Commit 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") extended check_map_func_compatibility() by enforcing map -> helper function match, but not helper -> map type match. Due to this all of the bpf_ringbuf_*() helper functions could be used with a wrong map type such as array or hash map, leading to invalid access due to type confusion. Also, both BPF_FUNC_ringbuf_{submit,discard} have ARG_PTR_TO_ALLOC_MEM as argument and not a BPF map. Therefore, their check_map_func_compatibility() presence is incorrect since it's only for map type checking.

2021-08-23Revert "media: dvb header files: move some headers to staging"Linus Torvalds
This reverts commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177. It turns out that some user-space applications use these uapi header files, so even though the only user of the interface is an old driver that was moved to staging, moving the header files causes unnecessary pain. Generally, we really don't want user space to use kernel headers directly (exactly because it causes pain when we re-organize), and instead copy them as needed. But these things happen, and the headers were in the uapi directory, so I guess it's not entirely unreasonable.

2021-08-23af_unix: Fix NULL pointer bug in unix_shutdownJiang Wang
Commit 94531cfcbe79 ("af_unix: Add unix_stream_proto for sockmap") introduced a bug for af_unix SEQPACKET type. In unix_shutdown, the unhash function will call prot->unhash(), which is NULL for SEQPACKET. And kernel will panic. On ARM32, it will show following messages: (it likely affects x86 too). Fix the bug by checking the prot->unhash is NULL or not first.

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for v5.15 First set of patches for v5.15. This got delayed as I have been mostly offline for the last few weeks. The biggest change is removal of prism54 driver, otherwise just smaller changes. Major changes: ath5k, ath9k, ath10k, ath11k: * switch from 'pci_' to 'dma_' API brcmfmac * allow per-board firmware binaries * add support 43752 SDIO device prism54 * remove the obsoleted driver, everyone should be using p54 driver instead ==================== Signed-off-by: David S.

2021-08-23net: sunhme: Remove unused macrosChristophe JAILLET
The usage of these macros has been removed in commit db1a8611c873 ("sunhme: Convert to pure OF driver."). So they can be removed. This simplifies code and helps for removing the wrappers in include/linux/pci-dma-compat.h. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S.

2021-08-23doc: Document unexpected tcp_l3mdev_accept=1 behaviorBenjamin Poirier
As suggested by David, document a somewhat unexpected behavior that results from net.ipv4.tcp_l3mdev_accept=1. This behavior was encountered while debugging FRR, a VRF-aware application, on a system which used net.ipv4.tcp_l3mdev_accept=1 and where TCP connections for BGP with MD5 keys were failing to establish.

2021-08-23net: dsa: track unique bridge numbers across all DSA switch treesVladimir Oltean
Right now, cross-tree bridging setups work somewhat by mistake. In the case of cross-tree bridging with sja1105, all switch instances need to agree upon a common VLAN ID for forwarding a packet that belongs to a certain bridging domain. With TX forwarding offload, the VLAN ID is the bridge VLAN for VLAN-aware bridging, and the tag_8021q TX forwarding offload VID (a VLAN which has non-zero VBID bits) for VLAN-unaware bridging. The VBID for VLAN-unaware bridging is derived from the dp->bridge_num value calculated by DSA independently for each switch tree. If ports from one tree join one bridge, and ports from another tree join another bridge, DSA will assign them the same bridge_num, even though the bridges are different. If cross-tree bridging is supported, this is an issue. Modify DSA to calculate the bridge_num globally across all switch trees. This has the implication for a driver that the dp->bridge_num value that DSA will assign to its ports might not be contiguous, if there are boards with multiple DSA drivers instantiated. Additionally, all bridge_num values eat up towards each switch's ds->num_fwd_offloading_bridges maximum, which is potentially unfortunate, and can be seen as a limitation introduced by this patch. However, that is the lesser evil for now. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-08-23net: stmmac: fix kernel panic due to NULL pointer dereference of plat->estWong Vee Khee
In the case of taprio offload is not enabled, the error handling path causes a kernel crash due to kernel NULL pointer deference. Fix this by adding check for NULL before attempt to access 'plat->est' on the mutex_lock() call. The following kernel panic is observed without this patch: RIP: 0010:mutex_lock+0x10/0x20 Call Trace: tc_setup_taprio+0x482/0x560 [stmmac] kmem_cache_alloc_trace+0x13f/0x490 taprio_disable_offload.isra.0+0x9d/0x180 [sch_taprio] taprio_destroy+0x6c/0x100 [sch_taprio] qdisc_create+0x2e5/0x4f0 tc_modify_qdisc+0x126/0x740 rtnetlink_rcv_msg+0x12b/0x380 _raw_spin_lock_irqsave+0x19/0x40 _raw_spin_unlock_irqrestore+0x18/0x30 create_object+0x212/0x340 rtnl_calcit.isra.0+0x110/0x110 netlink_rcv_skb+0x50/0x100 netlink_unicast+0x191/0x230 netlink_sendmsg+0x243/0x470 sock_sendmsg+0x5e/0x60 ____sys_sendmsg+0x20b/0x280 copy_msghdr_from_user+0x5c/0x90 __mod_memcg_state+0x87/0xf0 ___sys_sendmsg+0x7c/0xc0 lru_cache_add+0x7f/0xa0 _raw_spin_unlock+0x16/0x30 wp_page_copy+0x449/0x890 handle_mm_fault+0x921/0xfc0 __sys_sendmsg+0x59/0xa0 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xa9 ---[ end trace b1f19b24368a96aa ]--- Fixes: b60189e0392f ("net: stmmac: Integrate EST with TAPRIO scheduler API") Cc: <stable@vger.kernel.org> # 5.10.x Signed-off-by: Wong Vee Khee <vee.khee.wong@linux.intel.com> Signed-off-by: David S.
