2023-03-10mvpp2: take care of xdp_features when reconfiguring queuesMatteo Croce
XDP is supported only if enough queues are present, so when reconfiguring the queues set xdp_features accordingly.

2023-03-10net/mlx5e: take into account device reconfiguration for xdp_features flagLorenzo Bianconi
Take into account LRO and GRO configuration setting device xdp_features flag. Consider channel rq_wq_type enabling rx scatter-gatter support in xdp_features flag and disable NETDEV_XDP_ACT_NDO_XMIT_SG since it is not supported yet by the driver. Moreover always enable NETDEV_XDP_ACT_NDO_XMIT as the ndo_xdp_xmit callback does not require to load a dummy xdp program on the NIC.

2023-03-10i40e: Fix kernel crash during reboot when adapter is in recovery modeIvan Vecera
If the driver detects during probe that firmware is in recovery mode then i40e_init_recovery_mode() is called and the rest of probe function is skipped including pci_set_drvdata(). Subsequent i40e_shutdown() called during shutdown/reboot dereferences NULL pointer as pci_get_drvdata() returns NULL. To fix call pci_set_drvdata() also during entering to recovery mode.

2023-03-10ipvlan: Make skb->skb_iif track skb->dev for l3s modeJianguo Wu
For l3s mode, skb->dev is set to ipvlan interface in ipvlan_nf_input(): skb->dev = addr->master->dev but, skb->skb_iif remain unchanged, this will cause socket lookup failed if a target socket is bound to a interface, like the following example: ip link add ipvlan0 link eth0 type ipvlan mode l3s ip addr add dev ipvlan0 192.168.124.111/24 ip link set ipvlan0 up ping -c 1 -I ipvlan0 8.8.8.8 100% packet loss This is because there is no match sk in __raw_v4_lookup() as sk->sk_bound_dev_if != dif(skb->skb_iif). Fix this by make skb->skb_iif track skb->dev in ipvlan_nf_input().

2023-03-10fbdev: Fix incorrect page mapping clearance at fb_deferred_io_release()Takashi Iwai
The recent fix for the deferred I/O by the commit 3efc61d95259 ("fbdev: Fix invalid page access after closing deferred I/O devices") caused a regression when the same fb device is opened/closed while it's being used. It resulted in a frozen screen even if something is redrawn there after the close. The breakage is because the patch was made under a wrong assumption of a single open; in the current code, fb_deferred_io_release() cleans up the page mapping of the pageref list and it calls cancel_delayed_work_sync() unconditionally, where both are no correct behavior for multiple opens. This patch adds a refcount for the opens of the device, and applies the cleanup only when all files get closed. As both fb_deferred_io_open() and _close() are called always in the fb_info lock (mutex), it's safe to use the normal int for the refcounting. Also, a useless BUG_ON() is dropped.

KASAN reported follow problem: BUG: KASAN: use-after-free in lookup_rec Read of size 8 at addr ffff000199270ff0 by task modprobe CPU: 2 Comm: modprobe Call trace: kasan_report __asan_load8 lookup_rec ftrace_location arch_check_ftrace_location check_kprobe_address_safe register_kprobe When checking pg->records[pg->index - 1].ip in lookup_rec(), it can get a pg which is newly added to ftrace_pages_start in ftrace_process_locs(). Before the first pg->index++, index is 0 and accessing pg->records[-1].ip will cause this problem. Don't check the ip when pg->index is 0.

2023-03-09tracing: Check field value in hist_field_name()Steven Rostedt (Google)
The function hist_field_name() cannot handle being passed a NULL field parameter. It should never be NULL, but due to a previous bug, NULL was passed to the function and the kernel crashed due to a NULL dereference. Mark Rutland reported this to me on IRC. The bug was fixed, but to prevent future bugs from crashing the kernel, check the field and add a WARN_ON() if it is NULL.

2023-03-09tracing: Do not let histogram values have some modifiersSteven Rostedt (Google)
Histogram values can not be strings, stacktraces, graphs, symbols, syscalls, or grouped in buckets or log. Give an error if a value is set to do so. Note, the histogram code was not prepared to handle these modifiers for histograms and caused a bug.
