This is a wireless extensions style driver for 802.11b USB dongles, with partial support for cfg80211 interfaces. As these are all external dongles, there are probably few users that have not yet replaced them with cheap 802.11n devices that work better.

HostAP is an ISA/PCMCIA style 802.11b driver supporting only wireless extensions, and some custom ioctls (already removed). Some devices include a legacy PCI bridge but no DMA. The driver was marked obsolete in 2016 and is highly unlikely to still have any users. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kalle Valo <kvalo@kernel.org>

Cisco Aironet is an 802.11b PCMCIA and mini-PCI with limited support for Cardbus DMA and for CFG80211. Both PCMCIA and WEXT are deprecated, and there is little chance that anyone is still using this driver, so remove it.

Atmel at76c502/at76c504/at76c506 is a PIO-only (PCMCIA, mini-PCI and Cardbus) 802.11b driver with incomplete CFG80211 support. Both PCMCIA and WEXT are deprecated, and there is little chance that anyone is still using this driver, so remove it. The related at76c50x USB driver uses MAC80211 and remains.

PHY status IEs is used to have more information about received packets, such as RSSI and EVM. For each PHY IE type, it has different predefined PHY IE length, and the length are changed, so add them for WiFi 7 chips accordingly.

For WiFi 7 chips, some fields and predefined length are changed, so add them accordingly. The mac_id field is used to identify peer that send a packet, and we can use it to know RSSI and traffic from the peer. For WiFi 7 chips, RXWD.mac_id of PPDU status packet is not set by hardware. Instead, we should fill it by rxinfo_user[].mac_id of PPDU status content. Also, filter out invalid reports to prevent warning messages keep showing.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. `extra` is clearly supposed to be NUL-terminated which is evident by the manual NUL-byte assignment as well as its immediate usage with strlen(). Moreover, let's NUL-pad since there is deliberate effort (48 instances) made elsewhere to zero-out buffers in these getters and setters: 6050 | memset(local->config.nodeName, 0, sizeof(local->config.nodeName)); 6130 | memset(local->config.rates, 0, 8); 6139 | memset(local->config.rates, 0, 8); 6414 | memset(key.key, 0, MAX_KEY_SIZE); 6497 | memset(extra, 0, 16); (to be clear, strncpy also NUL-padded -- we are matching that behavior) Considering the above, a suitable replacement is `strscpy_pad` due to the fact that it guarantees both NUL-termination and NUL-padding on the destination buffer. We can also replace the hard-coded size of "16" to IW_ESSID_MAX_SIZE because this function is a wext handler. In wext-core.c we have: static const struct iw_ioctl_description standard_ioctl[] = { ... [IW_IOCTL_IDX(SIOCGIWNICKN)] = { .header_type = IW_HEADER_TYPE_POINT, .token_size = 1, .max_tokens = IW_ESSID_MAX_SIZE, }, So the buffer size is (strangely) IW_ESSID_MAX_SIZE Link: https://www.kernel.org/doc/html/latest/process/deprecated.html#strncpy-on-nul-terminated-strings [1] Link: https://github.com/KSPP/linux/issues/90 Cc: linux-hardening@vger.kernel.org Signed-off-by: Justin Stitt <justinstitt@google.com> Reviewed-by: Jeff Johnson <quic_jjohnson@quicinc.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026-strncpy-drivers-net-wireless-cisco-airo-c-v2-1-413427249e47@google.com

To make hardware efficient to determine if RX ring is full, introduce new design that checks if reading and writing indices are equal. Comparing to old design, initial indices of both reading and writing indices are 0 that means empty, and hardware checks full by "writing index + 1 == reading index". The "+1" has extra cost for hardware, so new design is to avoid this. Take ring size is 256 as an example, the initial reading and writing indices are 255 and 0 respectively; the initial values mean empty. If two indices are the same, for example 5 and 5, it means ring is full. wp rp used_cnt state 255 0 0 initial (ring is empty) 255 1 1 receive 1st packet 255 2 2 receive 2nd packet 0 2 1 driver read 1st packet 1 2 0 driver read 2nd packet (ring is empty) : 5 5 255 ring is full Note: 'rp' is hardware writing index Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026120049.9187-4-pkshih@realtek.com

PCI rings are used to DMA TX/RX packets. The address of WiFi 7 chips are different from previous ones, so add them according to hardware design. Another difference is that driver doesn't need to configure BD (buffer descriptor) RAM table, which is used by hardware to fetch BD ahead before fetching whole TX data. A TX ring contains numbers of TX BD (e.g. 512): TX BD (buffer descriptor; continual memory) +---+---+---+---+ +---+ | | | | | ... | | +-|-+---+---+---+ +---+ | | point to TX WD (WiFi descriptor; metadata of a skb data) v +------+ | | | | +-|----+ | | point to a skb data v +------+ | | | | +------+ Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026120049.9187-3-pkshih@realtek.com

Let's move away from using strncpy and instead use the more obvious interface for this context. For wlc->pub->srom_ccode, we're just copying two bytes from ccode into wlc->pub->srom_ccode with no expectation that srom_ccode be NUL-terminated: wlc->pub->srom_ccode is only used in regulatory_hint(): 1193 | if (wl->pub->srom_ccode[0] && 1194 | regulatory_hint(wl->wiphy, wl->pub->srom_ccode)) 1195 | wiphy_err(wl->wiphy, "%s: regulatory hint failed\n", __func__); We can see that only index 0 and index 1 are accessed. 3307 | int regulatory_hint(struct wiphy *wiphy, const char *alpha2) 3308 | { ... | ... 3322 | request->alpha2[0] = alpha2[0]; 3323 | request->alpha2[1] = alpha2[1]; ... | ... 3332 | } Since this is just a simple byte copy with correct lengths, let's use memcpy(). There should be no functional change. In a similar boat, both wlc->country_default and wlc->autocountry_default are just simple byte copies so let's use memcpy. However, FWICT they aren't used anywhere. (they should be used or removed -- not in scope of my patch, though).

Let's move away from using strncpy and instead favor a less ambiguous and more robust interface. For ifp->ndev->name, we expect ifp->ndev->name to be NUL-terminated based on its use in format strings within core.c: 67 | char *brcmf_ifname(struct brcmf_if *ifp) 68 | { 69 | if (!ifp) 70 | return "<if_null>"; 71 | 72 | if (ifp->ndev) 73 | return ifp->ndev->name; 74 | 75 | return "<if_none>"; 76 | } ... 288 | static netdev_tx_t brcmf_netdev_start_xmit(struct sk_buff *skb, 289 | struct net_device *ndev) { ... 330 | brcmf_dbg(INFO, "%s: insufficient headroom (%d)\n", 331 | brcmf_ifname(ifp), head_delta); ... 336 | bphy_err(drvr, "%s: failed to expand headroom\n", 337 | brcmf_ifname(ifp)); For di->name, we expect di->name to be NUL-terminated based on its usage with format strings: | brcms_dbg_dma(di->core, | "%s: DMA64 tx doesn't have AE set\n", | di->name); Looking at its allocation we can see that it is already zero-allocated which means NUL-padding is not required: | di = kzalloc(sizeof(struct dma_info), GFP_ATOMIC); For wlc->modulecb[i].name, we expect each name in wlc->modulecb to be NUL-terminated based on their usage with strcmp(): | if (!strcmp(wlc->modulecb[i].name, name) && NUL-padding is not required as wlc is zero-allocated in: brcms_c_attach_malloc() -> | wlc = kzalloc(sizeof(struct brcms_c_info), GFP_ATOMIC); For all these cases, a suitable replacement is `strscpy` due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

It does not include support for all device features, but enables basic functionality to load and pass traffic. Alice adds the 200G speed and PHY types supported by E830 hardware. Dan extends the DDP package logic to support the E830 package segment. Paul adds the basic registers and macros used by E830 hardware, and adds support for handling variable length link status information from firmware. Pawel removes some redundant zeroing of the PCI IDs list, and extends the list to include the E830 device IDs. ==================== Link: https://lore.kernel.org/r/20231025214157.1222758-1-jacob.e.keller@intel.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

McKenney. 7) Add a warning if NAPI callback missed xdp_do_flush() under CONFIG_DEBUG_NET which helps checking if drivers were missing the former, from Sebastian Andrzej Siewior. 8) Fix missed RCU read-lock in bpf_task_under_cgroup() which was throwing a warning under sleepable programs, from Yafang Shao. 9) Avoid unnecessary -EBUSY from htab_lock_bucket by disabling IRQ before checking map_locked, from Song Liu. 10) Make BPF CI linked_list failure test more robust, from Kumar Kartikeya Dwivedi. 11) Enable samples/bpf to be built as PIE in Fedora, from Viktor Malik. 12) Fix xsk starving when multiple xsk sockets were associated with a single xsk_buff_pool, from Albert Huang. 13) Clarify the signed modulo implementation for the BPF ISA standardization document that it uses truncated division, from Dave Thaler. 14) Improve BPF verifier's JEQ/JNE branch taken logic to also consider signed bounds knowledge, from Andrii Nakryiko. 15) Add an option to XDP selftests to use multi-buffer AF_XDP xdp_hw_metadata and mark used XDP programs as capable to use frags, from Larysa Zaremba. 16) Fix bpftool's BTF dumper wrt printing a pointer value and another one to fix struct_ops dump in an array, from Manu Bretelle. * tag 'for-netdev' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (51 commits) netkit: Remove explicit active/peer ptr initialization selftests/bpf: Fix selftests broken by mitigations=off samples/bpf: Allow building with custom bpftool samples/bpf: Fix passing LDFLAGS to libbpf samples/bpf: Allow building with custom CFLAGS/LDFLAGS bpf: Add more WARN_ON_ONCE checks for mismatched alloc and free selftests/bpf: Add selftests for netkit selftests/bpf: Add netlink helper library bpftool: Extend net dump with netkit progs bpftool: Implement link show support for netkit libbpf: Add link-based API for netkit tools: Sync if_link uapi header netkit, bpf: Add bpf programmable net device bpf: Improve JEQ/JNE branch taken logic bpf: Fold smp_mb__before_atomic() into atomic_set_release() bpf: Fix unnecessary -EBUSY from htab_lock_bucket xsk: Avoid starving the xsk further down the list bpf: print full verifier states on infinite loop detection selftests/bpf: test if state loops are detected in a tricky case bpf: correct loop detection for iterators convergence ... ==================== Link: https://lore.kernel.org/r/20231026150509.2824-1-daniel@iogearbox.netSigned-off-by: Jakub Kicinski <kuba@kernel.org>

The recent firmware interface change has added 2 counters in struct rx_port_stats_ext. This caused 2 stray ethtool counters to be displayed. Since new counters are added from time to time, fix it so that the ethtool logic will only display up to the maximum known counters. These 2 counters are not used by production firmware yet.

Davide reports that we look for the attr-cnt-name in the wrong object. We try to read it from the family, but the schema only allows for it to exist at attr-set level.

Page pool code is compiled conditionally, but the operations are part of the shared netlink family. We can handle this by reporting empty list of pools or -EOPNOTSUPP / -ENOSYS but the cleanest way seems to be removing the ops completely at compilation time. That way user can see that the page pool ops are not present using genetlink introspection. Same way they'd check if the kernel is "new enough" to support the ops. Extend the specs with the ability to specify the config condition under which op (and its policies, etc.) should be hidden.

struct nla_policy is usually constant itself, but unless we make the ranges inside constant we won't be able to make range structs const. The ranges are not modified by the core.

Avoid use of uninitialized state variable. In case of mlx5e_tx_reporter_build_diagnose_output_sq_common() it's better to still collect other data than bail out entirely.
