2023-08-03net: Space.h: Remove unused function declarationsYue Haibing
Commit 5aa83a4c0a15 (" [PATCH] remove two obsolete net drivers") remove fmv18x_probe(). And commmit 01f4685797a5 ("eth: amd: remove NI6510 support (ni65)") leave ni65_probe(). Commit a10079c66290 ("staging: remove hp100 driver") remove hp100 driver and hp100_probe() declaration is not used anymore. sonic_probe() and iph5526_probe() are never implemented since the beginning of git history.

2023-08-03mISDN: Update parameter type of dsp_cmx_send()Nathan Chancellor
When booting a kernel with CONFIG_MISDN_DSP=y and CONFIG_CFI_CLANG=y, there is a failure when dsp_cmx_send() is called indirectly from call_timer_fn(): [ 0.371412] CFI failure at call_timer_fn+0x2f/0x150 (target: dsp_cmx_send+0x0/0x530; expected type: 0x92ada1e9) The function pointer prototype that call_timer_fn() expects is void (*fn)(struct timer_list *) whereas dsp_cmx_send() has a parameter type of 'void *', which causes the control flow integrity checks to fail because the parameter types do not match. Change dsp_cmx_send()'s parameter type to be 'struct timer_list' to match the expected prototype. The argument is unused anyways, so this has no functional change, aside from avoiding the CFI failure.

2023-08-03tcp_metrics: fix addr_same() helperEric Dumazet
Because v4 and v6 families use separate inetpeer trees (respectively net->ipv4.peers and net->ipv6.peers), inetpeer_addr_cmp(a, b) assumes a & b share the same family. tcp_metrics use a common hash table, where entries can have different families.

2023-08-03prestera: fix fallback to previous version on same major versionJonas Gorski
When both supported and previous version have the same major version, and the firmwares are missing, the driver ends in a loop requesting the same (previous) version over and over again: [ 76.327413] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.1.img firmware, fall-back to previous 4.0 version [ 76.339802] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.352162] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.364502] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.376848] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.389183] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.401522] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.413860] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version [ 76.426199] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.0.img firmware, fall-back to previous 4.0 version ... Fix this by inverting the check to that we aren't yet at the previous version, and also check the minor version. This also catches the case where both versions are the same, as it was after commit bb5dbf2cc64d ("net: marvell: prestera: add firmware v4.0 support").

2023-08-03docs: net: page_pool: use kdoc to avoid duplicating the informationJakub Kicinski
All struct members of the driver-facing APIs are documented twice, in the code and under Documentation. This is a bit tedious. I also get the feeling that a lot of developers will read the header when coding, rather than the doc. Bring the two a little closer together by using kdoc for structs and functions. Using kdoc also gives us links (mentioning a function or struct in the text gets replaced by a link to its doc).

Using PP_FLAG_DMA_SYNC_DEV is a bit confusing. It was perhaps more obvious when it was introduced but the page pool use has grown beyond XDP and beyond packet-per-page so now making the heads and tails out of this feature is not trivial. Obviously making the API more user friendly would be a better fix, but until someone steps up to do that let's at least document what the parameters are. Relevant discussion in the first Link.

2023-08-03net: invert the netdevice.h vs xdp.h dependencyJakub Kicinski
xdp.h is far more specific and is included in only 67 other files vs netdevice.h's 1538 include sites. Make xdp.h include netdevice.h, instead of the other way around. This decreases the incremental allmodconfig builds size when xdp.h is touched from 5947 to 662 objects. Move bpf_prog_run_xdp() to xdp.h, seems appropriate and filter.h is a mega-header in its own right so it's nice to avoid xdp.h getting included there as well. The only unfortunate part is that the typedef for xdp_features_t has to move to netdevice.h, since its embedded in struct netdevice.

2023-08-03net: move struct netdev_rx_queue out of netdevice.hJakub Kicinski
struct netdev_rx_queue is touched in only a few places and having it defined in netdevice.h brings in the dependency on xdp.h, because struct xdp_rxq_info gets embedded in struct netdev_rx_queue. In prep for removal of xdp.h from netdevice.h move all the netdev_rx_queue stuff to a new header. We could technically break the new header up to avoid the sysfs.h include but it's so rarely included it doesn't seem to be worth it at this point.

When setting ZT0 via ptrace we do not currently force a reload of the floating point register state from memory, do that to ensure that the newly set value gets loaded into the registers on next task execution. The function was templated off the function for FPSIMD which due to our providing the option of embedding a FPSIMD regset within the SVE regset does not directly include the flush.

When setting SME vector lengths we clear TIF_SME to reenable SME traps, doing a reallocation of the backing storage on next use. We do this using clear_thread_flag() which operates on the current thread, meaning that when setting the vector length via ptrace we may both not force traps for the target task and force a spurious flush of any SME state that the tracing task may have.
