2023-09-30bpf: Use kmalloc_size_roundup() to adjust size_indexHou Tao
Commit d52b59315bf5 ("bpf: Adjust size_index according to the value of KMALLOC_MIN_SIZE") uses KMALLOC_MIN_SIZE to adjust size_index, but as reported by Nathan, the adjustment is not enough, because __kmalloc_minalign() also decides the minimal alignment of slab object as shown in new_kmalloc_cache() and its value may be greater than KMALLOC_MIN_SIZE (e.g., 64 bytes vs 8 bytes under a riscv QEMU VM). Instead of invoking __kmalloc_minalign() in bpf subsystem to find the maximal alignment, just using kmalloc_size_roundup() directly to get the corresponding slab object size for each allocation size. If these two sizes are unmatched, adjust size_index to select a bpf_mem_cache with unit_size equal to the object_size of the underlying slab cache for the allocation size. Fixes: 822fb26bdb55 ("bpf: Add a hint to allocated objects.")

2023-09-29bpf, mprog: Fix maximum program check on mprog attachmentDaniel Borkmann
After Paul's recent improvement to syzkaller to improve coverage for bpf_mprog and tcx, it hit a splat that the program limit was surpassed. What happened is that the maximum number of progs got added, followed by another prog add request which adds with BPF_F_BEFORE flag relative to the last program in the array. The idx >= bpf_mprog_max() check in bpf_mprog_attach() still passes because the index is below the maximum but the maximum will be surpassed. We need to add a check upfront for insertions to catch this situation.

2023-09-29bpf, sockmap: Reject sk_msg egress redirects to non-TCP socketsJakub Sitnicki
With a SOCKMAP/SOCKHASH map and an sk_msg program user can steer messages sent from one TCP socket (s1) to actually egress from another TCP socket (s2): tcp_bpf_sendmsg(s1) // = sk_prot->sendmsg tcp_bpf_send_verdict(s1) // __SK_REDIRECT case tcp_bpf_sendmsg_redir(s2) tcp_bpf_push_locked(s2) tcp_bpf_push(s2) tcp_rate_check_app_limited(s2) // expects tcp_sock tcp_sendmsg_locked(s2) // ditto There is a hard-coded assumption in the call-chain, that the egress socket (s2) is a TCP socket. However in commit 122e6c79efe1 ("sock_map: Update sock type checks for UDP") we have enabled redirects to non-TCP sockets. This was done for the sake of BPF sk_skb programs. There was no indention to support sk_msg send-to-egress use case. As a result, attempts to send-to-egress through a non-TCP socket lead to a crash due to invalid downcast from sock to tcp_sock: BUG: kernel NULL pointer dereference, address: 000000000000002f ...

2023-09-29bpf, sockmap: Do not inc copied_seq when PEEK flag setJohn Fastabend
When data is peek'd off the receive queue we shouldn't considered it copied from tcp_sock side. When we increment copied_seq this will confuse tcp_data_ready() because copied_seq can be arbitrarily increased. From application side it results in poll() operations not waking up when expected. Notice tcp stack without BPF recvmsg programs also does not increment copied_seq. We broke this when we moved copied_seq into recvmsg to only update when actual copy was happening. But, it wasn't working correctly either before because the tcp_data_ready() tried to use the copied_seq value to see if data was read by user yet. See fixes tags.

2023-09-29bpf: tcp_read_skb needs to pop skb regardless of seqJohn Fastabend
Before fix e5c6de5fa0258 tcp_read_skb() would increment the tp->copied-seq value. This (as described in the commit) would cause an error for apps because once that is incremented the application might believe there is no data to be read. Then some apps would stall or abort believing no data is available. However, the fix is incomplete because it introduces another issue in the skb dequeue. The loop does tcp_recv_skb() in a while loop to consume as many skbs as possible. The problem is the call is ... tcp_recv_skb(sk, seq, &offset) ... where 'seq' is: u32 seq = tp->copied_seq; Now we can hit a case where we've yet incremented copied_seq from BPF side, but then tcp_recv_skb() fails this test ... if (offset < skb->len || (TCP_SKB_CB(skb)->tcp_flags & TCPHDR_FIN)) ... so that instead of returning the skb we call tcp_eat_recv_skb() which frees the skb. This is because the routine believes the SKB has been collapsed per comment: /* This looks weird, but this can happen if TCP collapsing * splitted a fat GRO packet, while we released socket lock * in skb_splice_bits() */ This can't happen here we've unlinked the full SKB and orphaned it. Anyways it would confuse any BPF programs if the data were suddenly moved underneath it. To fix this situation do simpler operation and just skb_peek() the data of the queue followed by the unlink. It shouldn't need to check this condition and tcp_read_skb() reads entire skbs so there is no need to handle the 'offset!=0' case as we would see in tcp_read_sock().

2023-09-28ice: always add legacy 32byte RXDID in supported_rxdidsMichal Schmidt
When the PF and VF drivers both support flexible rx descriptors and have negotiated the VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC capability, the VF driver queries the PF for the list of supported descriptor formats (VIRTCHNL_OP_GET_SUPPORTED_RXDIDS). The PF driver is supposed to set the supported_rxdids bits that correspond to the descriptor formats the firmware implements. The legacy 32-byte rx desc format is always supported, even though it is not expressed in GLFLXP_RXDID_FLAGS. The ice driver does not advertise the legacy 32-byte rx desc support, which leads to this failure to bring up the VF using the Intel out-of-tree iavf driver: iavf 0000:41:01.0: PF does not list support for default Rx descriptor format ... iavf 0000:41:01.0: PF returned error -5 (VIRTCHNL_STATUS_ERR_PARAM) to our request 6 The in-tree iavf driver does not expose this bug, because it does not yet implement VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC. The ice driver must always set the ICE_RXDID_LEGACY_1 bit in supported_rxdids. The Intel out-of-tree ice driver and the ice driver in DPDK both do this. I copied this piece of the code and the comment text from the Intel out-of-tree driver.

2023-09-25wifi: mac80211: allow transmitting EAPOL frames with tainted keyWen Gong
Lower layer device driver stop/wake TX by calling ieee80211_stop_queue()/ ieee80211_wake_queue() while hw scan. Sometimes hw scan and PTK rekey are running in parallel, when M4 sent from wpa_supplicant arrive while the TX queue is stopped, then the M4 will pending send, and then new key install from wpa_supplicant. After TX queue wake up by lower layer device driver, the M4 will be dropped by below call stack. When key install started, the current key flag is set KEY_FLAG_TAINTED in ieee80211_pairwise_rekey(), and then mac80211 wait key install complete by lower layer device driver. Meanwhile ieee80211_tx_h_select_key() will return TX_DROP for the M4 in step 12 below, and then ieee80211_free_txskb() called by ieee80211_tx_dequeue(), so the M4 will not send and free, then the rekey process failed becaue AP not receive M4. Please see details in steps below. There are a interval between KEY_FLAG_TAINTED set for current key flag and install key complete by lower layer device driver, the KEY_FLAG_TAINTED is set in this interval, all packet including M4 will be dropped in this interval, the interval is step 8~13 as below. issue steps: TX thread install key thread 1. stop_queue -idle- 2. sending M4 -idle- 3. M4 pending -idle- 4. -idle- starting install key from wpa_supplicant 5. -idle- =>ieee80211_key_replace() 6. -idle- =>ieee80211_pairwise_rekey() and set currently key->flags |= KEY_FLAG_TAINTED 7. -idle- =>ieee80211_key_enable_hw_accel() 8. -idle- =>drv_set_key() and waiting key install complete from lower layer device driver 9. wake_queue -waiting state- 10. re-sending M4 -waiting state- 11. =>ieee80211_tx_h_select_key() -waiting state- 12. drop M4 by KEY_FLAG_TAINTED -waiting state- 13. -idle- install key complete with success/fail success: clear flag KEY_FLAG_TAINTED fail: start disconnect Hence add check in step 11 above to allow the EAPOL send out in the interval. If lower layer device driver use the old key/cipher to encrypt the M4, then AP received/decrypt M4 correctly, after M4 send out, lower layer device driver install the new key/cipher to hardware and return success. If lower layer device driver use new key/cipher to send the M4, then AP will/should drop the M4, then it is same result with this issue, AP will/ should kick out station as well as this issue. issue log: kworker/u16:4-5238 [000] 6456.108926: stop_queue: phy1 queue:0, reason:0 wpa_supplicant-961 [003] 6456.119737: rdev_tx_control_port: wiphy_name=phy1 name=wlan0 ifindex=6 dest=ARRAY[9e, 05, 31, 20, 9b, d0] proto=36488 unencrypted=0 wpa_supplicant-961 [003] 6456.119839: rdev_return_int_cookie: phy1, returned 0, cookie: 504 wpa_supplicant-961 [003] 6456.120287: rdev_add_key: phy1, netdev:wlan0(6), key_index: 0, mode: 0, pairwise: true, mac addr: 9e:05:31:20:9b:d0 wpa_supplicant-961 [003] 6456.120453: drv_set_key: phy1 vif:wlan0(2) sta:9e:05:31:20:9b:d0 cipher:0xfac04, flags=0x9, keyidx=0, hw_key_idx=0 kworker/u16:9-3829 [001] 6456.168240: wake_queue: phy1 queue:0, reason:0 kworker/u16:9-3829 [001] 6456.168255: drv_wake_tx_queue: phy1 vif:wlan0(2) sta:9e:05:31:20:9b:d0 ac:0 tid:7 kworker/u16:9-3829 [001] 6456.168305: cfg80211_control_port_tx_status: wdev(1), cookie: 504, ack: false wpa_supplicant-961 [003] 6459.167982: drv_return_int: phy1 - -110 issue call stack: nl80211_frame_tx_status+0x230/0x340 [cfg80211] cfg80211_control_port_tx_status+0x1c/0x28 [cfg80211] ieee80211_report_used_skb+0x374/0x3e8 [mac80211] ieee80211_free_txskb+0x24/0x40 [mac80211] ieee80211_tx_dequeue+0x644/0x954 [mac80211] ath10k_mac_tx_push_txq+0xac/0x238 [ath10k_core] ath10k_mac_op_wake_tx_queue+0xac/0xe0 [ath10k_core] drv_wake_tx_queue+0x80/0x168 [mac80211] __ieee80211_wake_txqs+0xe8/0x1c8 [mac80211] _ieee80211_wake_txqs+0xb4/0x120 [mac80211] ieee80211_wake_txqs+0x48/0x80 [mac80211] tasklet_action_common+0xa8/0x254 tasklet_action+0x2c/0x38 __do_softirq+0xdc/0x384 Signed-off-by: Wen Gong <quic_wgong@quicinc.com> Link: https://lore.kernel.org/r/20230801064751.25803-1-quic_wgong@quicinc.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull finegrained timestamp reverts from Christian Brauner: "Earlier this week we sent a few minor fixes for the multi-grained timestamp work in [1]. While we were polishing those up after Linus realized that there might be a nicer way to fix them we received a regression report in [2] that fine grained timestamps break gnulib tests and thus possibly other tools. The kernel will elide fine-grain timestamp updates when no one is actively querying for them to avoid performance impacts. So a sequence like write(f1) stat(f2) write(f2) stat(f2) write(f1) stat(f1) may result in timestamp f1 to be older than the final f2 timestamp even though f1 was last written too but the second write didn't update the timestamp. Such plotholes can lead to subtle bugs when programs compare timestamps. For example, the nap() function in [2] will estimate that it needs to wait one ns on a fine-grain timestamp enabled filesytem between subsequent calls to observe a timestamp change. But in general we don't update timestamps with more than one jiffie if we think that no one is actively querying for fine-grain timestamps to avoid performance impacts. While discussing various fixes the decision was to go back to the drawing board and ultimately to explore a solution that involves only exposing such fine-grained timestamps to nfs internally and never to userspace. As there are multiple solutions discussed the honest thing to do here is not to fix this up or disable it but to cleanly revert. The general infrastructure will probably come back but there is no reason to keep this code in mainline. The general changes to timestamp handling are valid and a good cleanup that will stay. The revert is fully bisectable" Link: https://lore.kernel.org/all/20230918-hirte-neuzugang-4c2324e7bae3@brauner [1] Link: https://lore.kernel.org/all/bf0524debb976627693e12ad23690094e4514303.camel@linuxfromscratch.org [2] * tag 'v6.6-rc3.vfs.ctime.revert' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: Revert "fs: add infrastructure for multigrain timestamps" Revert "btrfs: convert to multigrain timestamps" Revert "ext4: switch to multigrain timestamps" Revert "xfs: switch to multigrain timestamps" Revert "tmpfs: add support for multigrain timestamps"

2023-09-21igc: Expose tx-usecs coalesce setting to userMuhammad Husaini Zulkifli
When users attempt to obtain the coalesce setting using the ethtool command, current code always returns 0 for tx-usecs. This is because I225/6 always uses a queue pair setting, hence tx_coalesce_usecs does not return a value during the igc_ethtool_get_coalesce() callback process. The pair queue condition checking in igc_ethtool_get_coalesce() is removed by this patch so that the user gets information of the value of tx-usecs. Even if i225/6 is using queue pair setting, there is no harm in notifying the user of the tx-usecs. The implementation of the current code may have previously been a copy of the legacy code i210. Since I225 has the queue pair setting enabled, tx-usecs will always adhere to the user-set rx-usecs value. An error message will appear when the user attempts to set the tx-usecs value for the input parameters because, by default, they should only set the rx-usecs value. This patch also adds the helper function to get the previous rx coalesce value similar to tx coalesce. How to test: User can get the coalesce value using ethtool command. Example command: Get: ethtool -c <interface> Previous output: rx-usecs: 3 rx-frames: n/a rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 0 tx-frames: n/a tx-usecs-irq: n/a tx-frames-irq: n/a New output: rx-usecs: 3 rx-frames: n/a rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 3 tx-frames: n/a tx-usecs-irq: n/a tx-frames-irq: n/a Fixes: 8c5ad0dae93c ("igc: Add ethtool support") Signed-off-by: Muhammad Husaini Zulkifli <muhammad.husaini.zulkifli@intel.com> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Link: https://lore.kernel.org/r/20230919170331.1581031-1-anthony.l.nguyen@intel.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-09-20Bluetooth: Avoid redundant authenticationYing Hsu
While executing the Android 13 CTS Verifier Secure Server test on a ChromeOS device, it was observed that the Bluetooth host initiates authentication for an RFCOMM connection after SSP completes. When this happens, some Intel Bluetooth controllers, like AC9560, would disconnect with "Connection Rejected due to Security Reasons (0x0e)". Historically, BlueZ did not mandate this authentication while an authenticated combination key was already in use for the connection. This behavior was changed since commit 7b5a9241b780 ("Bluetooth: Introduce requirements for security level 4"). So, this patch addresses the aforementioned disconnection issue by restoring the previous behavior.

2023-09-20Revert "fs: add infrastructure for multigrain timestamps"Christian Brauner
This reverts commit ffb6cf19e06334062744b7e3493f71e500964f8e. Users reported regressions due to enabling multi-grained timestamps unconditionally. As no clear consensus on a solution has come up and the discussion has gone back to the drawing board revert the infrastructure changes for. If it isn't code that's here to stay, make it go away.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v6.6 Quite a large collection of fixes, with numbers boosted by multiple vendors sending multi-patch serieses. Nothing super major, and also one device quirk.
