2024-07-08bpf: Fix too early release of tcx_entryDaniel Borkmann
Pedro Pinto and later independently also Hyunwoo Kim and Wongi Lee reported an issue that the tcx_entry can be released too early leading to a use after free (UAF) when an active old-style ingress or clsact qdisc with a shared tc block is later replaced by another ingress or clsact instance. Essentially, the sequence to trigger the UAF (one example) can be as follows: 1. A network namespace is created 2. An ingress qdisc is created. This allocates a tcx_entry, and &tcx_entry->miniq is stored in the qdisc's miniqp->p_miniq. At the same time, a tcf block with index 1 is created. 3. chain0 is attached to the tcf block. chain0 must be connected to the block linked to the ingress qdisc to later reach the function tcf_chain0_head_change_cb_del() which triggers the UAF. 4. Create and graft a clsact qdisc. This causes the ingress qdisc created in step 1 to be removed, thus freeing the previously linked tcx_entry: rtnetlink_rcv_msg() => tc_modify_qdisc() => qdisc_create() => clsact_init() [a] => qdisc_graft() => qdisc_destroy() => __qdisc_destroy() => ingress_destroy() [b] => tcx_entry_free() => kfree_rcu() // tcx_entry freed 5. Finally, the network namespace is closed. This registers the cleanup_net worker, and during the process of releasing the remaining clsact qdisc, it accesses the tcx_entry that was already freed in step 4, causing the UAF to occur: cleanup_net() => ops_exit_list() => default_device_exit_batch() => unregister_netdevice_many() => unregister_netdevice_many_notify() => dev_shutdown() => qdisc_put() => clsact_destroy() [c] => tcf_block_put_ext() => tcf_chain0_head_change_cb_del() => tcf_chain_head_change_item() => clsact_chain_head_change() => mini_qdisc_pair_swap() // UAF There are also other variants, the gist is to add an ingress (or clsact) qdisc with a specific shared block, then to replace that qdisc, waiting for the tcx_entry kfree_rcu() to be executed and subsequently accessing the current active qdisc's miniq one way or another. The correct fix is to turn the miniq_active boolean into a counter. What can be observed, at step 2 above, the counter transitions from 0->1, at step [a] from 1->2 (in order for the miniq object to remain active during the replacement), then in [b] from 2->1 and finally [c] 1->0 with the eventual release. The reference counter in general ranges from [0,2] and it does not need to be atomic since all access to the counter is protected by the rtnl mutex. With this in place, there is no longer a UAF happening and the tcx_entry is freed at the correct time.

2024-07-08hwmon: (amc6821) Make reading and writing fan speed limits consistentGuenter Roeck
The default value of the maximum fan speed limit register is 0, essentially translating to an unlimited fan speed. When reading the limit, a value of 0 is reported in this case. However, writing a value of 0 results in writing a value of 0xffff into the register, which is inconsistent. To solve the problem, permit writing a limit of 0 for the maximim fan speed, effectively translating to "no limit". Write 0 into the register if a limit value of 0 is written. Otherwise limit the range to <1..6000000> and write 1..0xffff into the register. This ensures that reading and writing from and to a limit register return the same value while at the same time not changing reported values when reading the speed or limits. While at it, restrict fan limit writes to non-negative numbers; writing a negative limit does not make sense and should be reported instead of being corrected.

2024-07-08drm/bridge: adv7511: Fix Intermittent EDID failuresAdam Ford
In the process of adding support for shared IRQ pins, a scenario was accidentally created where adv7511_irq_process returned prematurely causing the EDID to fail randomly. Since the interrupt handler is broken up into two main helper functions, update both of them to treat the helper functions as IRQ handlers. These IRQ routines process their respective tasks as before, but if they determine that actual work was done, mark the respective IRQ status accordingly, and delay the check until everything has been processed. This should guarantee the helper functions don't return prematurely while still returning proper values of either IRQ_HANDLED or IRQ_NONE.

To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context.

2024-07-08mmc: mmc_spi: allow for spi controllers incapable of getting as low as 400kConor Dooley
Some controllers may not be able to reach a bus clock as low as 400 KHz due to a lack of sufficient divisors. In these cases, the SD card slot becomes non-functional as Linux continuously attempts to set the bus clock to 400 KHz. If the controller is incapable of getting that low, set its minimum frequency instead. While this may eliminate some SD cards, it allows those capable of operating at the controller's minimum frequency to be used.

2024-07-07perf dsos: When adding a dso into sorted dsos maintain the sort orderIan Rogers
dsos__add would add at the end of the dso array possibly requiring a later find to re-sort the array. Patterns of find then add were becoming O(n*log n) due to the sorts. Change the add routine to be O(n) rather than O(1) but to maintain the sorted-ness of the dsos array so that later finds don't need the O(n*log n) sort.
