soukjin bae reported a crash in tcp_v4_err() handling ICMP_DEST_UNREACH after tcp_write_queue_head(sk) returned a NULL pointer. Current logic should have prevented this : if (seq != tp->snd_una || !icsk->icsk_retransmits || !icsk->icsk_backoff || fastopen) break; Problem is the write queue might have been purged and icsk_backoff has not been cleared.

The function-local variable "delay" enters the loop interpreted as delay in bits. However, inside the loop it gets overwritten by the result of mlxsw_sp_pg_buf_delay_get(), and thus leaves the loop as quantity in cells. Thus on second and further loop iterations, the headroom for a given priority is configured with a wrong size. Fix by introducing a loop-local variable, delay_cells. Rename thres to thres_cells for consistency. Fixes: f417f04d ("mlxsw: spectrum: Refactor port buffer configuration") Signed-off-by:

Syzkaller again found a path to a kernel crash through bad gso input. By building an excessively large packet to cause an skb field to wrap. If VIRTIO_NET_HDR_F_NEEDS_CSUM was set this would have been dropped in skb_partial_csum_set. GSO packets that do not set checksum offload are suspicious and rare. Most callers of virtio_net_hdr_to_skb already pass them to skb_probe_transport_header. Move that test forward, change it to detect parse failure and drop packets on failure as those cleary are not one of the legitimate VIRTIO_NET_HDR_GSO types.

The features attribute is of type u64 and stored in the native endianes on the system. The for_each_set_bit() macro takes a pointer to a 32 bit array and goes over the bits in this area. On little Endian systems this also works with an u64 as the most significant bit is on the highest address, but on big endian the words are swapped. When we expect bit 15 here we get bit 47 (15 + 32). This patch converts it more or less to its own for_each_set_bit() implementation which works on 64 bit integers directly. This is then completely in host endianness and should work like expected. Fixes: fd867d51 ("net/core: generic support for disabling netdev features down stack") Signed-off-by:

The function prototype used to call JITed eBPF code (ie. the type of the struct bpf_prog bpf_func field) returns an unsigned int. The MIPS n64 ABI that MIPS64 kernels target defines that 32 bit integers should always be sign extended when passed in registers as either arguments or return values. This means that when returning any value which may not already be sign extended (ie. of type REG_64BIT or REG_32BIT_ZERO_EX) we need to perform that sign extension in order to comply with the n64 ABI. Without this we see strange looking test failures from test_bpf.ko, such as: test_bpf: #65 ALU64_MOV_X: dst = 4294967295 jited:1 ret -1 != -1 FAIL (1 times) Although the return value printed matches the expected value, this is only because printf is only examining the least significant 32 bits of the 64 bit register value we returned. The register holding the expected value is sign extended whilst the v0 register was set to a zero extended value by our JITed code, so when compared by a conditional branch instruction the values are not equal. We already handle this when the return value register is of type REG_32BIT_ZERO_EX, so simply extend this to also cover REG_64BIT. Signed-off-by:

The starting of AP interface can fail due to invalid beacon interval, which does not match the minimum gcd requirement set by the wifi driver. In such case, the beacon interval of that interface gets updated with that invalid beacon interval. The next time that interface is brought up in AP mode, an interface combination check is performed and the beacon interval is taken from the previously set value. In a case where an invalid beacon interval, i.e. a beacon interval value which does not satisfy the minimum gcd criteria set by the driver, is set, all the subsequent trials to bring that interface in AP mode will fail, even if the subsequent trials have a valid beacon interval. To avoid this, in case of a failure in bringing up an interface in AP mode due to interface combination error, the interface beacon interval which is stored in bss conf, needs to be restored with the last working value of beacon interval. Tested on ath10k using WCN3990. Cc: stable@vger.kernel.org Fixes: 0c317a02 ("cfg80211: support virtual interfaces with different beacon intervals") Signed-off-by:

Herbert Xu authored
The mesh table code walks over hash tables for two purposes. First of all it's used as part of a netlink dump process, but it is also used for looking up entries to delete using criteria other than the hash key. The second purpose is directly contrary to the design specification of rhashtable walks. It is only meant for use by netlink dumps. This is because rhashtable is resizable and you cannot obtain a stable walk over it during a resize process. In fact mesh's use of rhashtable for dumping is bogus too. Rather than using rhashtable walk's iterator to keep track of the current position, it always converts the current position to an integer which defeats the purpose of the iterator. Therefore this patch converts all uses of rhashtable walk into a simple linked list. This patch also adds a new spin lock to protect the hash table insertion/removal as well as the walk list modifications. In fact the previous code was buggy as the removals can race with each other, potentially resulting in a double-free. Cc: stable@vger.kernel.org Signed-off-by:

When provisioning a new data block for a virtual block, either because the block was previously unallocated or because we are breaking sharing, if the whole block of data is being overwritten the bio that triggered the provisioning is issued immediately, skipping copying or zeroing of the data block. When this bio completes the new mapping is inserted in to the pool's metadata by process_prepared_mapping(), where the bio completion is signaled to the upper layers. This completion is signaled without first committing the metadata. If the bio in question has the REQ_FUA flag set and the system crashes right after its completion and before the next metadata commit, then the write is lost despite the REQ_FUA flag requiring that I/O completion for this request must only be signaled after the data has been committed to non-volatile storage. Fix this by deferring the completion of overwrite bios, with the REQ_FUA flag set, until after the metadata has been committed. Cc: stable@vger.kernel.org Signed-off-by:
