If the loop fails, the "while(trials--) {" loop will exit with "trials" set to -1. The test for that expects it to end with "trials" set to 0 so the warning message will not be printed. Fix this by changing from a post-op to a pre-op. This does mean that we only make 99 attempts instead of 100 but that's okay.

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by replacing /* fall through */ comments with the new pseudo-keyword macro fallthrough; instead of letting the code fall through to the next case. Notice that Clang doesn't recognize /* fall through */ comments as implicit fall-through markings. Link: https://github.com/KSPP/linux/issues/115Signed-off-by:

Linux network drivers normally disallow changing the MAC address when the interface is up. This driver has been different in that it allows to change the MAC address *only* when it's up. This patch brings wilc1000 behavior more in line with other network drivers. We could have replaced wilc_set_mac_addr() with eth_mac_addr() but that would break existing documentation on how to change the MAC address. Likewise, return -EADDRNOTAVAIL (not -EINVAL) when the specified MAC address is invalid or unavailable. Signed-off-by:

The driver so far has always disabled CRC protection. This means any data corruption that occurrs during the SPI transfers could go undetected. This patch adds module parameters enable_crc7 and enable_crc16 to selectively turn on CRC7 (for command transfers) and CRC16 (for data transfers), respectively. The default configuration remains unchanged, with both CRC7 and CRC16 off. The performance impact of CRC was measured by running ttcp -t four times in a row on a SAMA5 device: CRC7 CRC16 Throughput: Standard deviation: ---- ----- ----------- ------------------- off off 1720 +/- 48 KB/s on off 1658 +/- 58 KB/s on on 1579 +/- 84 KB/s Signed-off-by:

The WILC1000 protocol control register has bits for enabling the CRCs (CRC7 for commands and CRC16 for data) and to set the data packet size. Define symbolic names for those so the code is more easily understood. Signed-off-by:

For CMD_SINGLE_READ and CMD_INTERNAL_READ, WILC may insert one or more zero bytes between the command response and the DATA Start tag (0xf3). This behavior appears to be undocumented in "ATWILC1000 USER GUIDE" (https://tinyurl.com/4hhshdts) but we have observed 1-4 zero bytes when the SPI bus operates at 48MHz and none when it operates at 1MHz. This code is derived from the equivalent code of the wilc driver in the linux-at91 repository. Signed-off-by:

There are a few reasons not to dump SSIDs as-is in kernel logs: 1) they're not guaranteed to be any particular text encoding (UTF-8, ASCII, ...) in general 2) it's somewhat redundant; the BSSID should be enough to uniquely identify the AP/STA to which we're connecting 3) BSSIDs have an easily-recognized format, whereas SSIDs do not (they are free-form) 4) other common drivers (e.g., everything based on mac80211) get along just fine by only including BSSIDs when logging state transitions Additional notes on reason #3: this is important for the privacy-conscious, especially when providing tools that convey kernel logs on behalf of a user -- e.g., when reporting bugs. So for example, it's easy to automatically filter logs for MAC addresses, but it's much harder to filter SSIDs out of unstructured text. Signed-off-by:

Normally, the bootloader will already initialize the MAC address registers of the ENETC and the driver will just use them or generate a random one, if it is not initialized. Add a new way to provide the MAC address: via device tree. Besides the usual 'mac-address' property, there is also the possibility to fetch it via a NVMEM provider. The sl28 board stores the MAC address in the SPI NOR flash OTP region. Having this will allow linux to fetch the MAC address from there without being dependent on the bootloader. No in-tree boards have the device tree properties set, thus for these, this is a no-op. Signed-off-by:

the commit 1ddc3229 ("skbuff: remove some unnecessary operation in skb_segment_list()") introduces an issue very similar to the one already fixed by commit 53475c5d ("net: fix use-after-free when UDP GRO with shared fraglist"). If the GSO skb goes though skb_clone() and pskb_expand_head() before entering skb_segment_list(), the latter will unshare the frag_list skbs and will release the old list. With the reverted commit in place, when skb_segment_list() completes, skb->next points to the just released list, and later on the kernel will hit UaF. Note that since commit e0e3070a ("udp: properly complete L4 GRO over UDP tunnel packet") the critical scenario can be reproduced also receiving UDP over vxlan traffic with: NIC (NETIF_F_GRO_FRAGLIST enabled) -> vxlan -> UDP sink Attaching a packet socket to the NIC will cause skb_clone() and the tunnel decapsulation will call pskb_expand_head().

Ivan Bornyakov says: ==================== net: phy: marvell-88x2222: a couple of improvements First, there are some SFP modules that only uses RX_LOS for link indication. Add check that link is operational before actual read of line-side status. Second, it is invalid to set 10G speed without autonegotiation, according to phy_ethtool_ksettings_set(). Implement switching between 10GBase-R and 1000Base-X/SGMII if autonegotiation can't complete but there is signal in line. Changelog: v1 -> v2: * make checking that link is operational more friendly for trancievers without SFP cages. * split swapping 1G/10G modes into non-functional and functional commits for the sake of easier review. ==================== Signed-off-by: -

Setting 10G without autonegotiation is invalid according to phy_ethtool_ksettings_set(). Thus, we need to set it during autonegotiation. If 1G autonegotiation can't complete for quite a time, but there is signal in line, switch line interface type to 10GBase-R, if supported, in hope for link to be established. And vice versa. If 10GBase-R link can't be established for quite a time, and autonegotiation is enabled, and there is signal in line, switch line interface type to appropriate 1G mode, i.e. 1000Base-X or SGMII, if supported.

Some SFP modules uses RX_LOS for link indication. In such cases link will be always up, even without cable connected. RX_LOS changes will trigger link_up()/link_down() upstream operations. Thus, check that SFP link is operational before actual read link status. If there is no SFP cage connected to the tranciever, check only PMD Recieve Signal Detect register. Signed-off-by:
