Fix boot crash on Raspberry Pi by moving the update to `event->datalen` before data is copied into flexible-array member `data` via `memcpy()`. Flexible-array member `data` was annotated with `__counted_by(datalen)` in commit 62d19b35 ("wifi: brcmfmac: fweh: Add __counted_by for struct brcmf_fweh_queue_item and use struct_size()"). The intention of this is to gain visibility into the size of `data` at run-time through its _counter_ (in this case `datalen`), and with this have its accesses bounds-checked at run-time via CONFIG_FORTIFY_SOURCE and CONFIG_UBSAN_BOUNDS. To effectively accomplish the above, we shall update the counter (`datalen`), before the first access to the flexible array (`data`), which was also done in the mentioned commit. However, commit edec4282 ("wifi: brcmfmac: allow per-vendor event handling") inadvertently caused a buffer overflow, detected by FORTIFY_SOURCE. It moved the `event->datalen = datalen;` update to after the first `data` access, at which point `event->datalen` was not yet updated from zero (after calling `kzalloc()`), leading to the overflow issue. This fix repositions the `event->datalen = datalen;` update before accessing `data`, restoring the intended buffer overflow protection. :) Fixes: edec4282 ("wifi: brcmfmac: allow per-vendor event handling") Reported-by:

Through the routine bond_mii_monitor(), bonding driver inspects and commits the slave state changes. During the times when slave state change and failure in aqcuiring rtnl lock happen at the same time, the routine bond_mii_monitor() reschedules itself to come around after 1 msec to commit the new state. During this, it executes the routine bond_miimon_inspect() to re-inspect the state chane and prints the corresponding slave state on to the console. Hence we do see a message at every 1 msec till the rtnl lock is acquired and state chage is committed. This patch doesn't change how bond functions. It only simply limits this kind of log flood.

Patches 2 and 3 consolidate nf_log NULL checks and introduces extra boundary checks on family and type to make it clear that no out of bounds access will happen.

Patch 4, also from Pablo, gets rid of unneeded conditional in nft_osf init function. Patch 5, from myself, fixes erroneous Kconfig dependencies that came in an earlier net-next pull request. This should get rid of the xtables related build failure reports. Patches 6 to 10 are an update to nftables' concatenated-ranges set type to speed up element insertions. This series also compacts a few data structures and cleans up a few oddities such as reliance on ZERO_SIZE_PTR when asking to allocate a set with no elements. From myself. Patches 11 moves the nf_reinject function from the netfilter core (vmlinux) into the nfnetlink_queue backend, the only location where this is called from. Also from myself.

Pull tracing fix from Steven Rostedt: - While working on the ring buffer I noticed that the counter used for knowing where the end of the data is on a sub-buffer was not a full "int" but just 20 bits. It was masked out to 0xfffff. With the new code that allows the user to change the size of the sub-buffer, it is theoretically possible to ask for a size bigger than 2^20. If that happens, unexpected results may occur as there's no code checking if the counter overflowed the 20 bits of the write mask. There are other checks to make sure events fit in the sub-buffer, but if the sub-buffer itself is too big, that is not checked. Add a check in the resize of the sub-buffer to make sure that it never goes beyond the size of the counter that holds how much data is on it. * tag 'trace-v6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Do not let subbuf be bigger than write mask

Michael Chan says: ==================== bnxt_en: Ntuple filter improvements The current Ntuple filter implementation has a limitation on 5750X (P5) and newer chips. The destination ring of the ntuple filter must be a valid ring in the RSS indirection table. Ntuple filters may not work if the RSS indirection table is modified by the user to only contain a subset of the rings. If an ntuple filter is set to a ring destination that is not in the RSS indirection table, the packet matching that filter will be placed in a random ring instead of the specified destination ring. This series of patches will fix the problem by using a separate VNIC for ntuple filters. The default VNIC will be dedicated for RSS and so the indirection table can be setup in any way and will not affect ntuple filters using the separate VNIC. Quite a bit of refactoring is needed to do the the VNIC and RSS context accounting in the first few patches. This is technically a bug fix, but I think the changes are too big for -net. ==================== Link: https://lore.kernel.org/r/20240220230317.96341-1-michael.chan@broadcom.comSigned-off-by:

Allocate and setup the additional VNIC for ntuple filters if this new method is supported by the firmware. Even though this VNIC is only used for ntuple filters with direct ring destinations, we still setup the RSS hash to be identical to the default VNIC so that each RX packet will have the correct hash in the RX completion. This VNIC is always at VNIC index BNXT_VNIC_NTUPLE. Reviewed-by:

Pavan Chebbi authored
On newer chips that support the ring table index method for ntuple filters, the current scheme of using the same VNIC for both RSS and ntuple filters will not work in all cases. An ntuple filter can only be directed to a destination ring if that destination ring is also in the RSS indirection table. To support ntuple filters with any arbitratry RSS indirection table that may only include a subset of the rings, we need to use a separate VNIC for ntuple filters. This patch provisions the additional VNIC. The next patch will allocate additional VNIC from firmware and set it up. Reviewed-by:
