They both expect the result from a prior bpf_ringbuf_reserve() call which has a return type of RET_PTR_TO_ALLOC_MEM_OR_NULL. Meaning, after a NULL check in the code, the verifier will promote the register type in the non-NULL branch to a PTR_TO_MEM and in the NULL branch to a known zero scalar. Generally, pointer arithmetic on PTR_TO_MEM is allowed, so the latter could have an offset. The ARG_PTR_TO_ALLOC_MEM expects a PTR_TO_MEM register type. However, the non- zero result from bpf_ringbuf_reserve() must be fed into either bpf_ringbuf_submit() or bpf_ringbuf_discard() but with the original offset given it will then read out the struct bpf_ringbuf_hdr mapping. The verifier missed to enforce a zero offset, so that out of bounds access can be triggered which could be used to escalate privileges if unprivileged BPF was enabled (disabled by default in kernel).

[PATCH] iio: afe: rescale: Fix logic bug

by Linus Walleij

When introducing support for processed channels I needed to invert the expression: if (!iio_channel_has_info(schan, IIO_CHAN_INFO_RAW) || !iio_channel_has_info(schan, IIO_CHAN_INFO_SCALE)) dev_err(dev, "source channel does not support raw/scale\n"); To the inverse, meaning detect when we can usse raw+scale rather than when we can not. This was the result: if (iio_channel_has_info(schan, IIO_CHAN_INFO_RAW) || iio_channel_has_info(schan, IIO_CHAN_INFO_SCALE)) dev_info(dev, "using raw+scale source channel\n"); Ooops. Spot the error. Yep old George Boole came up and bit me. That should be an &&. The current code "mostly works" because we have not run into systems supporting only raw but not scale or only scale but not raw, and I doubt there are few using the rescaler on anything such, but let's fix the logic.

[PATCH 1/1] net: cdc_ncm: Allow for dwNtbOutMaxSize to be unset or zero

by Lee Jones

Currently, due to the sequential use of min_t() and clamp_t() macros, in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is not set, the logic sets tx_max to 0. This is then used to allocate the data area of the SKB requested later in cdc_ncm_fill_tx_frame(). This does not cause an issue presently because when memory is allocated during initialisation phase of SKB creation, more memory (512b) is allocated than is required for the SKB headers alone (320b), leaving some space (512b - 320b = 192b) for CDC data (172b). However, if more elements (for example 3 x u64 = [24b]) were added to one of the SKB header structs, say 'struct skb_shared_info', increasing its original size (320b [320b aligned]) to something larger (344b [384b aligned]), then suddenly the CDC data (172b) no longer fits in the spare SKB data area (512b - 384b = 128b). Consequently the SKB bounds checking semantics fails and panics: skbuff: skb_over_panic: text:ffffffff830a5b5f len:184 put:172 \ head:ffff888119227c00 data:ffff888119227c00 tail:0xb8 end:0x80 dev:<NULL> ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:110!

MADV_FREE may split THPs if it is called for partial THP. It may trigger the below race: CPU A CPU B ----- ----- smaps walk: MADV_FREE: page_mapcount() PageCompound() split_huge_page() page = compound_head(page) PageDoubleMap(page) When calling PageDoubleMap() this page is not a tail page of THP anymore so the BUG is triggered. This could be fixed by elevated refcount of the page before calling mapcount, but it prevents from counting migration entries, and it seems overkilling because the race just could happen when PMD is split so all PTE entries of tail pages are actually migration entries, and smaps_account() does treat migration entries as mapcount == 1 as Kirill pointed out. Add a new parameter for smaps_account() to tell this entry is migration entry then skip calling page_mapcount(). Don't skip getting mapcount for device private entries since they do track references with mapcount. Pagemap also has the similar issue although it was not reported. Fixed it as well.

[PATCH 3/9] bfq: Split shared queues on move between cgroups

by Jan Kara

When bfqq is shared by multiple processes it can happen that one of the processes gets moved to a different cgroup (or just starts submitting IO for different cgroup). In case that happens we need to split the merged bfqq as otherwise we will have IO for multiple cgroups in one bfqq and we will just account IO time to wrong entities etc. Similarly if the bfqq is scheduled to merge with another bfqq but the merge didn't happen yet, cancel the merge as it need not be valid anymore.

[PATCH v2] mtd: spi-nor: Check for zero erase size in spi_nor_find_best_erase_type()

by Alexander A Sverdlin

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> Erase can be zeroed in spi_nor_parse_4bait() or spi_nor_init_non_uniform_erase_map().

[PATCH] virt: acrn: obtain pa from VMA with PFNMAP flag

by Yonghua Huang

acrn_vm_ram_map can't pin the user pages with VM_PFNMAP flag by calling get_user_pages_fast(), the PA(physical pages) may be mapped by kernel driver and set PFNMAP flag. This patch fixes logic to setup EPT mapping for PFN mapped RAM region by checking the memory attribute before adding EPT mapping for them.
