2025-09-19bpf: disable and remove registers chain based livenessEduard Zingerman1-25/+0
Remove register chain based liveness tracking: - struct bpf_reg_state->{parent,live} fields are no longer needed; - REG_LIVE_WRITTEN marks are superseded by bpf_mark_stack_write() calls; - mark_reg_read() calls are superseded by bpf_mark_stack_read(); - log.c:print_liveness() is superseded by logging in liveness.c; - propagate_liveness() is superseded by bpf_update_live_stack(); - no need to establish register chains in is_state_visited() anymore; - fix a bunch of tests expecting "_w" suffixes in verifier log messages.

2025-09-19bpf: signal error if old liveness is more conservative than newEduard Zingerman1-0/+1
Unlike the new algorithm, register chain based liveness tracking is fully path sensitive, and thus should be strictly more accurate. Validate the new algorithm by signaling an error whenever it considers a stack slot dead while the old algorithm considers it alive.

2025-09-19bpf: callchain sensitive stack liveness tracking using CFGEduard Zingerman1-0/+14
This commit adds a flow-sensitive, context-sensitive, path-insensitive data flow analysis for live stack slots: - flow-sensitive: uses program control flow graph to compute data flow values; - context-sensitive: collects data flow values for each possible call chain in a program; - path-insensitive: does not distinguish between separate control flow graph paths reaching the same instruction. Compared to the current path-sensitive analysis, this approach trades some precision for not having to enumerate every path in the program. This gives a theoretical capability to run the analysis before main verification pass. See cover letter for motivation. The basic idea is as follows: - Data flow values indicate stack slots that might be read and stack slots that are definitely written. - Data flow values are collected for each (call chain, instruction number) combination in the program. - Within a subprogram, data flow values are propagated using control flow graph. - Data flow values are transferred from entry instructions of callee subprograms to call sites in caller subprograms. In other words, a tree of all possible call chains is constructed. Each node of this tree represents a subprogram. Read and write marks are collected for each instruction of each node. Live stack slots are first computed for lower level nodes. Then, information about outer stack slots that might be read or are definitely written by a subprogram is propagated one level up, to the corresponding call instructions of the upper nodes. Procedure repeats until root node is processed. In the absence of value range analysis, stack read/write marks are collected during main verification pass, and data flow computation is triggered each time verifier.c:states_equal() needs to query the information. Implementation details are documented in kernel/bpf/liveness.c. Quantitative data about verification performance changes and memory consumption is in the cover letter.

2025-09-19bpf: compute instructions postorder per subprogramEduard Zingerman1-1/+5
The next patch would require doing postorder traversal of individual subprograms. Facilitate this by moving env->cfg.insn_postorder computation from check_cfg() to a separate pass, as check_cfg() descends into called subprograms (and it needs to, because of merge_callee_effects() logic). env->cfg.insn_postorder is used only by compute_live_registers(), this function does not track cross subprogram dependencies, thus the change does not affect it's operation.

Merge series from Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com>: All the Qualcomm WCD codecs and WCD based codecs have lots of code in common, resulting in lot of duplicate code. This series is an attempt to clean some of this by moving the common code to wcd-common library or to soundwire helper functions. Currently I have done cleanups for 4 codecs wcd934x, wcd937x, wcd938x and wcd939x, however any new Qualcomm codecs can avoid this duplication by using the wcd-common library. I have also added two helpers of_sdw_find_device_by_node() and sdw_slave_get_current_bank() in soundwire layer for the codecs to use them, this series was already acked by Soundwire maintainer Vinod. As original cleanup series was depending on the new soundwire interfaces I have combined both the series as they are cleaning up code duplications. As am touching the same codec drivers, 2 bug fixes are also added at the start of the series. There is still lot of code that is duplicate, but this is just a starting point for such cleanups. I have tested this on T14s, any testing is appreciated.

2025-09-19nsfs: support exhaustive file handlesChristian Brauner1-0/+1
Pidfd file handles are exhaustive meaning they don't require a handle on another pidfd to pass to open_by_handle_at() so it can derive the filesystem to decode in. Instead it can be derived from the file handle itself. The same is possible for namespace file handles.

2025-09-19nsfs: support file handlesChristian Brauner2-0/+15
A while ago we added support for file handles to pidfs so pidfds can be encoded and decoded as file handles. Userspace has adopted this quickly and it's proven very useful. Implement file handles for namespaces as well. A process is not always able to open /proc/self/ns/. That requires procfs to be mounted and for /proc/self/ or /proc/self/ns/ to not be overmounted. However, userspace can always derive a namespace fd from a pidfd. And that always works for a task's own namespace. There's no need to introduce unnecessary behavioral differences between /proc/self/ns/ fds, pidfd-derived namespace fds, and file-handle-derived namespace fds. So namespace file handles are always decodable if the caller is located in the namespace the file handle refers to. This also allows a task to e.g., store a set of file handles to its namespaces in a file on-disk so it can verify when it gets rexeced that they're still valid and so on. This is akin to the pidfd use-case. Or just plainly for namespace comparison reasons where a file handle to the task's own namespace can be easily compared against others.

There can be multiple inode switch works that are trying to switch inodes to / from the same wb. This can happen in particular if some cgroup exits which owns many (thousands) inodes and we need to switch them all. In this case several inode_switch_wbs_work_fn() instances will be just spinning on the same wb->list_lock while only one of them makes forward progress. This wastes CPU cycles and quickly leads to softlockup reports and unusable system. Instead of running several inode_switch_wbs_work_fn() instances in parallel switching to the same wb and contending on wb->list_lock, run just one work item per wb and manage a queue of isw items switching to this wb.

2025-09-19wifi: cfg80211: correctly implement and validate S1G chandefLachlan Hodges2-0/+110
Currently, the S1G channelisation implementation differs from that of VHT, which is the PHY that S1G is based on. The major difference between the clock rate is 1/10th of VHT. However how their channelisation is represented within cfg80211 and mac80211 vastly differ. To rectify this, remove the use of IEEE80211_CHAN_1/2/4.. flags that were previously used to indicate the control channel width, however it should be implied that the control channels are 1MHz in the case of S1G. Additionally, introduce the invert - being IEEE80211_CHAN_NO_4/8/16MHz - that imply the control channel may not be used for a certain bandwidth. With these new flags, we can perform regulatory and chandef validation just as we would for VHT. To deal with the notion that S1G PHYs may contain a 2MHz primary channel, introduce a new variable, s1g_primary_2mhz, which indicates whether we are operating on a 2MHz primary channel. In this case, the chandef::chan points to the 1MHz primary channel pointed to by the primary channel location. Alongside this, introduce some new helper routines that can extract the sibling 1MHz channel. The sibling being the alternate 1MHz primary subchannel within the 2MHz primary channel that is not pointed to by chandef::chan. Furthermore, due to unique restrictions imposed on S1G PHYs, introduce a new flag, IEEE80211_CHAN_S1G_NO_PRIMARY, which states that the 1MHz channel cannot be used as a primary channel. This is assumed to be set by vendors as it is hardware and regdom specific, When we validate a 2MHz primary channel, we need to ensure both 1MHz subchannels do not contain this flag. If one or both of the 1MHz subchannels contain this flag then the 2MHz primary is not permitted for use as a primary channel. Properly integrate S1G channel validation such that it is implemented according with other PHY types such as VHT. Additionally, implement a new S1G-specific regulatory flag to allow cfg80211 to understand specific vendor requirements for S1G PHYs.
