From: Nick Desaulniers <ndesaulniers@google.com> stable inclusion from stable-5.10.77 commit 6ad8bbc9d301145335c35f29ed7878b61b0ad81f bugzilla: 185677 https://gitee.com/openeuler/kernel/issues/I4IAP7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit e6a0c958bdf9b2e1b57501fc9433a461f0a6aadd upstream. A kernel built with CONFIG_THUMB2_KERNEL=y and using clang as the assembler could generate non-naturally-aligned v7wbi_tlb_fns which results in a boot failure. The original commit adding the macro missed the .align directive on this data.

When frame pointers are used instead of the ARM unwinder, and the kernel is built using clang with an external assembler and CONFIG_XIP_KERNEL, every file produces two warnings like: arm-linux-gnueabi-ld: warning: orphan section `.ARM.extab' from `net/mac802154/util.o' being placed in section `.ARM.extab' arm-linux-gnueabi-ld: warning: orphan section `.ARM.exidx' from `net/mac802154/util.o' being placed in section `.ARM.exidx' The same fix was already merged for the normal (non-XIP) linker script, with a longer description.

This reverts commit a49d784d5a8272d0f63c448fe8dc69e589db006e. The updated binding was wrong / invalid and has been reverted. There isn't any upstream kernel DTS using it and Broadcom isn't known to use it neither. There is close to zero chance this will cause regression for anyone. Actually in-kernel bcm5301x.dtsi still uses the old good binding and so it's broken since the driver update. This revert fixes it.

During probing, the driver tries to get a list (mask) of supported command types in port100_get_command_type_mask() function. The value is u64 and 0 is treated as invalid mask (no commands supported). The function however returns also -ERRNO as u64 which will be interpret as valid command mask. Return 0 on every error case of port100_get_command_type_mask(), so the probing will stop.

In this case MediaTek mmc host controller will keep the value for HALT state after CQE disable/enable flow, so the next CQE transfer after resume will be timeout due to CQE is in HALT state, the log as below: <4>.(4)[318:kworker/4:1H]mmc0: cqhci: timeout for tag 2 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: ============ CQHCI REGISTER DUMP =========== <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Caps: 0x100020b6 | Version: 0x00000510 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Config: 0x00001103 | Control: 0x00000001 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Int stat: 0x00000000 | Int enab: 0x00000006 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Int sig: 0x00000006 | Int Coal: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: TDL base: 0xfd05f000 | TDL up32: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Doorbell: 0x8000203c | TCN: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Dev queue: 0x00000000 | Dev Pend: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Task clr: 0x00000000 | SSC1: 0x00001000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: SSC2: 0x00000001 | DCMD rsp: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: RED mask: 0xfdf9a080 | TERRI: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Resp idx: 0x00000000 | Resp arg: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: CRNQP: 0x00000000 | CRNQDUN: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: CRNQIS: 0x00000000 | CRNQIE: 0x00000000 This change check HALT state after CQE enable, if CQE is in HALT state, we will clear it.

To reset standard tuning circuit completely, after clear ESDHC_MIX_CTRL_EXE_TUNE, also need to clear bit buffer_read_ready, this operation will finally clear the USDHC IP internal logic flag execute_tuning_with_clr_buf, make sure the following normal data transfer will not be impacted by standard tuning logic used before. Find this issue when do quick SD card insert/remove stress test. During standard tuning prodedure, if remove SD card, USDHC standard tuning logic can't clear the internal flag execute_tuning_with_clr_buf. Next time when insert SD card, all data related commands can't get any data related interrupts, include data transfer complete interrupt, data timeout interrupt, data CRC interrupt, data end bit interrupt. Always trigger software timeout issue. Even reset the USDHC through bits in register SYS_CTRL (0x2C, bit28 reset tuning, bit26 reset data, bit 25 reset command, bit 24 reset all) can't recover this. From the user's point of view, USDHC stuck, SD can't be recognized any more.

We should not access request members after the last send, even to determine if indeed it was the last data payload send. The reason is that a completion could have arrived and trigger a new execution of the request which overridden these members. This was fixed by commit 825619b09ad3 ("nvme-tcp: fix possible use-after-completion"). Commit e371af033c56 broke that assumption again to address cases where multiple r2t pdus are sent per request. To fix it, we need to record the request data_sent and data_len and after the payload network send we reference these counters to determine weather we should advance the request iterator.

The management registrations locking was broken, the list was locked for each wdev, but cfg80211_mgmt_registrations_update() iterated it without holding all the correct spinlocks, causing list corruption. Rather than trying to fix it with fine-grained locking, just move the lock to the wiphy/rdev (still need the list on each wdev), we already need to hold the wdev lock to change it, so there's no contention on the lock in any case. This trivially fixes the bug since we hold one wdev's lock already, and now will hold the lock that protects all lists.

Currently collapse_file does not explicitly check PG_writeback, instead, page_has_private and try_to_release_page are used to filter writeback pages. This does not work for xfs with blocksize equal to or larger than pagesize, because in such case xfs has no page->private. This makes collapse_file bail out early for writeback page. Otherwise, xfs end_page_writeback will panic as follows. page:fffffe00201bcc80 refcount:0 mapcount:0 mapping:ffff0003f88c86a8 index:0x0 pfn:0x84ef32 aops:xfs_address_space_operations [xfs] ino:30000b7 dentry name:"libtest.so" flags: 0x57fffe0000008027(locked|referenced|uptodate|active|writeback) raw: 57fffe0000008027 ffff80001b48bc28 ffff80001b48bc28 ffff0003f88c86a8 raw: 0000000000000000 0000000000000000 00000000ffffffff ffff0000c3e9a000 page dumped because: VM_BUG_ON_PAGE(((unsigned int) page_ref_count(page) + 127u <= 127u)) page->mem_cgroup:ffff0000c3e9a000 ------------[ cut here ]------------ kernel BUG at include/linux/mm.h:1212!

The bpf_jit_binary_free() function requires a non-NULL argument. When the RISC-V BPF JIT fails to converge in NR_JIT_ITERATIONS steps, jit_data->header will be NULL, which triggers a NULL dereference. Avoid this by checking the argument, prior calling the function.

Lorenzo noticed that the code testing for program type compatibility of tail call maps is potentially racy in that two threads could encounter a map with an unset type simultaneously and both return true even though they are inserting incompatible programs. The race window is quite small, but artificially enlarging it by adding a usleep_range() inside the check in bpf_prog_array_compatible() makes it trivial to trigger from userspace with a program that does, essentially: map_fd = bpf_create_map(BPF_MAP_TYPE_PROG_ARRAY, 4, 4, 2, 0); pid = fork(); if (pid) { key = 0; value = xdp_fd; } else { key = 1; value = tc_fd; } err = bpf_map_update_elem(map_fd, &key, &value, 0); While the race window is small, it has potentially serious ramifications in that triggering it would allow a BPF program to tail call to a program of a different type. So let's get rid of it by protecting the update with a spinlock. The commit in the Fixes tag is the last commit that touches the code in question. v2: - Use a spinlock instead of an atomic variable and cmpxchg() (Alexei) v3: - Put lock and the members it protects into an embedded 'owner' struct (Daniel) Fixes: 3324b584b6f6 ("ebpf: misc core cleanup") Reported-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20211026110019.363464-1-toke@redhat.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Chen Jun <chenjun102@huawei.com> Acked-by: Weilong Chen <chenweilong@huawei.com> Signed-off-by: Chen Jun <chenjun102@huawei.com> --- include/linux/bpf.h | 7 +++++-- kernel/bpf/arraymap.c | 1 + kernel/bpf/core.c | 20 +++++++++++++------- kernel/bpf/syscall.c | 6 ++++-- 4 files changed, 23 insertions(+), 11 deletions(-) diff --git a/include/linux/bpf.h b/include/linux/bpf.h index fc83187082ed..89b07eaf4415 100644 --- a/include/linux/bpf.h +++ b/include/linux/bpf.h @@ -862,8 +862,11 @@ struct bpf_array_aux { * stored in the map to make sure that all callers and callees have * the same prog type and JITed flag. */ - enum bpf_prog_type type; - bool jited; + struct { + spinlock_t lock; + enum bpf_prog_type type; + bool jited; + } owner; /* Programs with direct jumps into programs part of this array. */ struct list_head poke_progs; struct bpf_map *map; diff --git a/kernel/bpf/arraymap.c b/kernel/bpf/arraymap.c index c6c81eceb68f..36c68dcea236 100644 --- a/kernel/bpf/arraymap.c +++ b/kernel/bpf/arraymap.c @@ -1025,6 +1025,7 @@ static struct bpf_map *prog_array_map_alloc(union bpf_attr *attr) INIT_WORK(&aux->work, prog_array_map_clear_deferred); INIT_LIST_HEAD(&aux->poke_progs); mutex_init(&aux->poke_mutex); + spin_lock_init(&aux->owner.lock); map = array_map_alloc(attr); if (IS_ERR(map)) { diff --git a/kernel/bpf/core.c b/kernel/bpf/core.c index 2e4a658d65d6..72e4bf0ee546 100644 --- a/kernel/bpf/core.c +++ b/kernel/bpf/core.c @@ -1775,20 +1775,26 @@ static unsigned int __bpf_prog_ret0_warn(const void *ctx, bool bpf_prog_array_compatible(struct bpf_array *array, const struct bpf_prog *fp) { + bool ret; + if (fp->kprobe_override) return false; - if (!array->aux->type) { + spin_lock(&array->aux->owner.lock); + + if (!array->aux->owner.type) { /* There's no owner yet where we could check for * compatibility. */ - array->aux->type = fp->type; - array->aux->jited = fp->jited; - return true; + array->aux->owner.type = fp->type; + array->aux->owner.jited = fp->jited; + ret = true; + } else { + ret = array->aux->owner.type == fp->type && + array->aux->owner.jited == fp->jited; } - - return array->aux->type == fp->type && - array->aux->jited == fp->jited; + spin_unlock(&array->aux->owner.lock); + return ret; } static int bpf_check_tail_call(const struct bpf_prog *fp) diff --git a/kernel/bpf/syscall.c b/kernel/bpf/syscall.c index 9433ab9995cd..9cae74a75d6c 100644 --- a/kernel/bpf/syscall.c +++ b/kernel/bpf/syscall.c @@ -535,8 +535,10 @@ static void bpf_map_show_fdinfo(struct seq_file *m, struct file *filp) if (map->map_type == BPF_MAP_TYPE_PROG_ARRAY) { array = container_of(map, struct bpf_array, map); - type = array->aux->type; - jited = array->aux->jited; + spin_lock(&array->aux->owner.lock); + type = array->aux->owner.type; + jited = array->aux->owner.jited; + spin_unlock(&array->aux->owner.lock); } seq_printf(m, -- 2.20.1

With commit db5ad6b7f8cd ("nvme-tcp: try to send request in queue_rq context") r2t and response PDU can get processed while send function is executing. Current data digest send code uses req->offset after kernel_sendmsg(), this creates a race condition where req->offset gets reset before it is used in send function. This can happen in two cases - 1. Target sends r2t PDU which resets req->offset. 2. Target send response PDU which completes the req and then req is used for a new command, nvme_tcp_setup_cmd_pdu() resets req->offset. Fix this by storing req->offset in a local variable and using this local variable after kernel_sendmsg().

Syzbot reported ODEBUG warning in batadv_nc_mesh_free(). The problem was in wrong error handling in batadv_mesh_init(). Before this patch batadv_mesh_init() was calling batadv_mesh_free() in case of any batadv_*_init() calls failure. This approach may work well, when there is some kind of indicator, which can tell which parts of batadv are initialized; but there isn't any. All written above lead to cleaning up uninitialized fields. Even if we hide ODEBUG warning by initializing bat_priv->nc.work, syzbot was able to hit GPF in batadv_nc_purge_paths(), because hash pointer in still NULL. [1] To fix these bugs we can unwind batadv_*_init() calls one by one. It is good approach for 2 reasons: 1) It fixes bugs on error handling path 2) It improves the performance, since we won't call unneeded batadv_*_free() functions. So, this patch makes all batadv_*_init() clean up all allocated memory before returning with an error to no call correspoing batadv_*_free() and open-codes batadv_mesh_free() with proper order to avoid touching uninitialized fields.

When perf.data is not written cleanly, we would like to process existing data as much as possible (please see f_header.data.size == 0 condition in perf_session__read_header). However, perf.data with partial data may crash perf. Specifically, we see crash in 'perf script' for NULL session->header.env.arch. Fix this by checking session->header.env.arch before using it to determine native_arch. Also split the if condition so it is easier to read. Committer notes: If it is a pipe, we already assume is a native arch, so no need to check session->header.env.arch.
