2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann2-2/+2
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

2021-04-13of: net: pass the dst buffer to of_get_mac_address()Michael Walle1-4/+3
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

2020-09-25drivers/net/ethernet: clean up mis-targeted commentsJesse Brandeburg1-19/+27
As part of the W=1 cleanups for ethernet, a million [*] driver comments had to be cleaned up to get the W=1 compilation to succeed. This change finally makes the drivers/net/ethernet tree compile with W=1 set on the command line. NOTE: The kernel uses kdoc style (see Documentation/process/kernel-doc.rst) when documenting code, not doxygen or other styles. After this patch the x86_64 build has no warnings from W=1, however scripts/kernel-doc says there are 1545 more warnings in source files, that I need to develop a script to fix in a followup patch. The errors fixed here are all kdoc of a few classes, with a few outliers: In file included from drivers/net/ethernet/qlogic/netxen/netxen_nic_hw.c:10: drivers/net/ethernet/qlogic/netxen/netxen_nic.h:1193:18: warning: ‘FW_DUMP_LEVELS’ defined but not used [-Wunused-const-variable=] 1193 | static const u32 FW_DUMP_LEVELS[] = { 0x3, 0x7, 0xf, 0x1f, 0x3f, 0x7f, 0xff }; | ^~~~~~~~~~~~~~ ... repeats 4 times... drivers/net/ethernet/sun/cassini.c:2084:24: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] 2084 | RX_USED_ADD(page, i); drivers/net/ethernet/natsemi/ns83820.c: In function ‘phy_intr’: drivers/net/ethernet/natsemi/ns83820.c:603:6: warning: variable ‘tbisr’ set but not used [-Wunused-but-set-variable] 603 | u32 tbisr, tanar, tanlpar; | ^~~~~ drivers/net/ethernet/natsemi/ns83820.c: In function ‘ns83820_get_link_ksettings’: drivers/net/ethernet/natsemi/ns83820.c:1207:11: warning: variable ‘tanar’ set but not used [-Wunused-but-set-variable] 1207 | u32 cfg, tanar, tbicr; | ^~~~~ drivers/net/ethernet/packetengines/yellowfin.c:1063:18: warning: variable ‘yf_size’ set but not used [-Wunused-but-set-variable] 1063 | int data_size, yf_size; | ^~~~~~~ Normal kdoc fixes: warning: Function parameter or member 'x' not described in 'y' warning: Excess function parameter 'x' description in 'y' warning: Cannot understand <string> on line <NNN> - I thought it was a doc line [*] - ok it wasn't quite a million, but it felt like it.

This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.

2020-02-23net: ks8851-ml: Fix IRQ handling and lockingMarek Vasut1-6/+8
The KS8851 requires that packet RX and TX are mutually exclusive. Currently, the driver hopes to achieve this by disabling interrupt from the card by writing the card registers and by disabling the interrupt on the interrupt controller. This however is racy on SMP. Replace this approach by expanding the spinlock used around the ks_start_xmit() TX path to ks_irq() RX path to assure true mutual exclusion and remove the interrupt enabling/disabling, which is now not needed anymore. Furthermore, disable interrupts also in ks_net_stop(), which was missing before. Note that a massive improvement here would be to re-use the KS8851 driver approach, which is to move the TX path into a worker thread, interrupt handling to threaded interrupt, and synchronize everything with mutexes, but that would be a much bigger rework, for a separate patch.

2020-02-16net: ks8851-ml: Remove 8-bit bus accessorsMarek Vasut1-40/+5
This driver is mixing 8-bit and 16-bit bus accessors for reasons unknown, however the speculation is that this was some sort of attempt to support the 8-bit bus mode. As per the KS8851-16MLL documentation, all two registers accessed via the 8-bit accessors are internally 16-bit registers, so reading them using 16-bit accessors is fine. The KS_CCR read can be converted to 16-bit read outright, as it is already a concatenation of two 8-bit reads of that register. The KS_RXQCR accesses are 8-bit only, however writing the top 8 bits of the register is OK as well, since the driver caches the entire 16-bit register value anyway. Finally, the driver is not used by any hardware in the kernel right now. The only hardware available to me is one with 16-bit bus, so I have no way to test the 8-bit bus mode, however it is unlikely this ever really worked anyway. If the 8-bit bus mode is ever required, it can be easily added by adjusting the 16-bit accessors to do 2 consecutive accesses, which is how this should have been done from the beginning.
