2024-04-23tcp: Fix Use-After-Free in tcp_ao_connect_initHyunwoo Kim1-1/+2
Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal of tcp_ao_connect_init, is not part of the RCU read critical section, it is possible that the RCU grace period will pass during the traversal and the key will be free. To prevent this, it should be changed to hlist_for_each_entry_safe.

Some usb drivers try to set small skb->truesize and break core networking stacks. In this patch, I removed one of the skb->truesize overide. I also replaced one skb_clone() by an allocation of a fresh and small skb, to get minimally sized skbs, like we did in commit 1e2c61172342 ("net: cdc_ncm: reduce skb truesize in rx path") Fixes: f8ebb3ac881b ("net: usb: ax88179_178a: Fix packet receiving") Reported-by: shironeko <[email protected]> Closes: https://lore.kernel.org/netdev/[email protected]/ Signed-off-by: Eric Dumazet <[email protected]> Cc: Jose Alonso <[email protected]> Reviewed-by: Simon Horman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2024-04-23net: fix sk_memory_allocated_{add|sub} vs softirqsEric Dumazet1-18/+20
Jonathan Heathcote reported a regression caused by blamed commit on aarch64 architecture. x86 happens to have irq-safe __this_cpu_add_return() and __this_cpu_sub(), but this is not generic. I think my confusion came from "struct sock" argument, because these helpers are called with a locked socket. But the memory accounting is per-proto (and per-cpu after the blamed commit). We might cleanup these helpers later to directly accept a "struct proto *proto" argument. Switch to this_cpu_add_return() and this_cpu_xchg() operations, and get rid of preempt_disable()/preempt_enable() pairs. Fast path becomes a bit faster as a result :) Many thanks to Jonathan Heathcote for his awesome report and investigations.

2024-04-23Revert "NFSD: Reschedule CB operations when backchannel rpc_clnt is shut down"Chuck Lever1-18/+2
The reverted commit attempted to enable NFSD to retransmit pending callback operations if an NFS client disconnects, but unintentionally introduces a hazardous behavior regression if the client becomes permanently unreachable while callback operations are still pending. A disconnect can occur due to network partition or if the NFS server needs to force the NFS client to retransmit (for example, if a GSS window under-run occurs). Reverting the commit will make NFSD behave the same as it did in v6.8 and before. Pending callback operations are permanently lost if the client connection is terminated before the client receives them. For some callback operations, this loss is not harmful. However, for CB_RECALL, the loss means a delegation might be revoked unnecessarily. For CB_OFFLOAD, pending COPY operations will never complete unless the NFS client subsequently sends an OFFLOAD_STATUS operation, which the Linux NFS client does not currently implement. These issues still need to be addressed somehow. Reported-by: Dai Ngo <[email protected]> Link: https://bugzilla.kernel.org/show_bug.cgi?id=218735 Signed-off-by: Chuck Lever <[email protected]>

2024-04-23kbuild: rust: remove unneeded `@rustc_cfg` to avoid ICEMiguel Ojeda1-1/+0
When KUnit tests are enabled, under very big kernel configurations (e.g. `allyesconfig`), we can trigger a `rustdoc` ICE [1]: RUSTDOC TK rust/kernel/lib.rs error: the compiler unexpectedly panicked. this is a bug. The reason is that this build step has a duplicated `@rustc_cfg` argument, which contains the kernel configuration, and thus a lot of arguments. The factor 2 happens to be enough to reach the ICE. Thus remove the unneeded `@rustc_cfg`. By doing so, we clean up the command and workaround the ICE. The ICE has been fixed in the upcoming Rust 1.79 [2].

2024-04-22NFC: trf7970a: disable all regulators on removalPaul Geurts1-19/+23
During module probe, regulator 'vin' and 'vdd-io' are used and enabled, but the vdd-io regulator overwrites the 'vin' regulator pointer. During remove, only the vdd-io is disabled, as the vin regulator pointer is not available anymore. When regulator_put() is called during resource cleanup a kernel warning is given, as the regulator is still enabled. Store the two regulators in separate pointers and disable both the regulators on module remove.

mv88e6250_phylink_get_caps() With the recent PHYLINK changes requiring supported_interfaces to be set, MV88E6250 family switches like the 88E6020 fail to probe - cmode is never initialized on these devices, so mv88e6250_phylink_get_caps() does not set any supported_interfaces flags. Instead of a cmode, on 88E6250 we have a read-only port mode value that encodes similar information.

commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system memory accesses") modified cpc_read()/cpc_write() to use access_width to read CPC registers. However, for PCC registers the access width field in the ACPI register macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is incorrectly treated as access width. This causes errors when reading from PCC registers in the CPPC driver. For PCC registers, base the size of read/write on the bit width field. The debug message in cpc_read()/cpc_write() is updated to print relevant information for the address space type used to read the register.

2024-04-22cxl/core: Fix potential payload size confusion in cxl_mem_get_poison()Dan Williams1-21/+17
A recent change to cxl_mem_get_records_log() [1] highlighted a subtle nuance of looping calls to cxl_internal_send_cmd(), i.e. that cxl_internal_send_cmd() modifies the 'size_out' member of the @mbox_cmd argument. That mechanism is useful for communicating underflow, but it is unwanted when reusing @mbox_cmd for a subsequent submission. It turns out that cxl_xfer_log() avoids this scenario by always redefining @mbox_cmd each iteration. Update cxl_mem_get_records_log() and cxl_mem_get_poison() to follow the same style as cxl_xfer_log(), i.e. re-define @mbox_cmd each iteration. The cxl_mem_get_records_log() change is just a style fixup, but the cxl_mem_get_poison() change is a potential fix, per Alison [2]: Poison list retrieval can hit this case if the MORE flag is set and a follow on read of the list delivers more records than the previous read. ie. device gives one record, sets the _MORE flag, then gives 5. Not an urgent fix since this behavior has not been seen in the wild, but worth tracking as a fix.

2024-04-22sched/eevdf: Prevent vlag from going out of bounds in reweight_eevdf()Xuewen Yan1-6/+12
It was possible to have pick_eevdf() return NULL, which then causes a NULL-deref. This turned out to be due to entity_eligible() returning falsely negative because of a s64 multiplcation overflow. Specifically, reweight_eevdf() computes the vlag without considering the limit placed upon vlag as update_entity_lag() does, and then the scaling multiplication (remember that weight is 20bit fixed point) can overflow. This then leads to the new vruntime being weird which then causes the above entity_eligible() to go side-ways and claim nothing is eligible. Thus limit the range of vlag accordingly. All this was quite rare, but fatal when it does happen.

On older (pre-MLD API) devices, we started also calling iwl_mvm_set_link_mapping()/iwl_mvm_unset_link_mapping(), but of course not also iwl_mvm_remove_link(). Since the link ID was only released in iwl_mvm_remove_link() this causes us to run out of FW link IDs very quickly. Fix it by releasing the link ID correctly.

2024-04-22bcachefs: If we run merges at a lower watermark, they must be nonblockingKent Overstreet1-1/+5
Fix another deadlock related to the merge path; previously, we switched to always running merges at a lower watermark (because they are noncritical); but when we run at a lower watermark we also need to run nonblocking or we've introduced a new deadlock.

2024-04-22arm64: dts: imx8mp: Fix assigned-clocks for second CSI2Marek Vasut1-1/+1
The first CSI2 pixel clock are supplied from IMX8MP_CLK_MEDIA_CAM1_PIX_ROOT, the second CSI2 pixel clock are supplied from IMX8MP_CLK_MEDIA_CAM2_PIX_ROOT, both clock are supplied from SYS_PLL2 and configured using assigned-clock DT properties. Each CSI2 DT node configures its IMX8MP_CLK_MEDIA_CAMn_PIX_ROOT clock. This used to be the case until likely a copy-paste error in commit f78835d1e616 ("arm64: dts: imx8mp: reparent MEDIA_MIPI_PHY1_REF to CLK_24M") which changed the second CSI2 node to configure IMX8MP_CLK_MEDIA_CAM1_PIX_ROOT using its assigned-clocks property. Fix the second CSI2 assigned-clock property back to the original correct IMX8MP_CLK_MEDIA_CAM2_PIX_ROOT .
