2021-04-13of: net: pass the dst buffer to of_get_mac_address()Michael Walle
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.

2021-04-12net: phy: marvell: fix detection of PHY on Topaz switchesPali Rohár
Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading"), Linux reports the temperature of Topaz hwmon as constant -75°C. This is because switches from the Topaz family (88E6141 / 88E6341) have the address of the temperature sensor register different from Peridot. This address is instead compatible with 88E1510 PHYs, as was used for Topaz before the above mentioned commit. Create a new mapping table between switch family and PHY ID for families which don't have a model number. And define PHY IDs for Topaz and Peridot families. Create a new PHY ID and a new PHY driver for Topaz's internal PHY. The only difference from Peridot's PHY driver is the HWMON probing method. Prior this change Topaz's internal PHY is detected by kernel as: PHY [...] driver [Marvell 88E6390] (irq=63) And afterwards as: PHY [...] driver [Marvell 88E6341 Family] (irq=63) Signed-off-by: Pali Rohár <pali@kernel.org> BugLink: https://github.com/globalscaletechnologies/linux/issues/1 Fixes: fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading") Reviewed-by: Marek Behún <kabel@kernel.org> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2021-04-12vfio/mdev: Correct the function signatures for the mdev_type_attributesJason Gunthorpe
The driver core standard is to pass in the properly typed object, the properly typed attribute and the buffer data. It stems from the root kobject method: ssize_t (*show)(struct kobject *kobj, struct kobj_attribute *attr,..) Each subclass of kobject should provide their own function with the same signature but more specific types, eg struct device uses: ssize_t (*show)(struct device *dev, struct device_attribute *attr,..) In this case the existing signature is: ssize_t (*show)(struct kobject *kobj, struct device *dev,..) Where kobj is a 'struct mdev_type *' and dev is 'mdev_type->parent->dev'. Change the mdev_type related sysfs attribute functions to: ssize_t (*show)(struct mdev_type *mtype, struct mdev_type_attribute *attr,..) In order to restore type safety and match the driver core standard There are no current users of 'attr', but if it is ever needed it would be hard to add in retroactively, so do it now.

2021-04-12vfs: add fileattr opsMiklos Szeredi
There's a substantial amount of boilerplate in filesystems handling FS_IOC_[GS]ETFLAGS/ FS_IOC_FS[GS]ETXATTR ioctls. Also due to userspace buffers being involved in the ioctl API this is difficult to stack, as shown by overlayfs issues related to these ioctls. Introduce a new internal API named "fileattr" (fsxattr can be confused with xattr, xflags is inappropriate, since this is more than just flags). There's significant overlap between flags and xflags and this API handles the conversions automatically, so filesystems may choose which one to use. In ->fileattr_get() a hint is provided to the filesystem whether flags or xattr are being requested by userspace, but in this series this hint is ignored by all filesystems, since generating all the attributes is cheap. If a filesystem doesn't implemement the fileattr API, just fall back to f_op->ioctl(). When all filesystems are converted, the fallback can be removed. 32bit compat ioctls are now handled by the generic code as well. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

2021-04-11phy: sfp: add netlink SFP support to generic SFP codeAndrew Lunn
The new netlink API for reading SFP data requires a new op to be implemented. The idea of the new netlink SFP code is that userspace is responsible to parsing the EEPROM data and requesting pages, rather than have the kernel decide what pages are interesting and returning them. This allows greater flexibility for newer formats. Currently the generic SFP code only supports simple SFPs. Allow i2c address 0x50 and 0x51 to be accessed with page and bank must always be 0. This interface will later be extended when for example QSFP support is added.

git://git.kernel.org/pub/scm/linux/kernel/git/mani/mhi into char-misc-next Manivannan writes: MHI changes for v5.13 core: - Added support for Flash Programmer execution environment which allows the host machine (like x86) to flash the modem firmware to NAND or eMMC in the modem. The MHI bus will expose EDL channels (34, 35) and then the opensource QDL tool [1] can be used to flash the firmware from the host. - Added an internal helper for polling the MHI registers with a retry interval. This helper is used now to poll for the MHI ready state in MHI STATUS register. - Various fixes for issues found during the bringup of SDX24/SDX55 based Quectel and Telit modems. - Updates to the Execution environment handling for proper downloading of the AMSS image from SBL (Secondary Bootloader) mode. - Added support for sending STOP channel command to the MHI device and also made changes to the MHI core for proper handling of stop and restart. - Fixed the runtime_pm handling in the core by forcing the device to be in wake mode until TX completion and allowing it to suspend for RX. - Added sanity checks for values read from the device to avoid crash if those are corrupted somehow. - Fixed warnings generated by sparse (W=2) - Couple of kernel doc cleanups in mhi.h pci_generic: - Added support for runtime PM and generic PM - Added Firehose channels for flashing the firmware - Added support for modems such as Quectel EM1XXGR-L, SDX24, SDX65, Foxconn T99W175 exposing relevant channels.

2021-04-10i2c: ensure timely release of driver-allocated resourcesDmitry Torokhov
More and more drivers rely on devres to manage their resources, however if bus' probe() and release() methods are not trivial and control some of resources as well (for example enable or disable clocks, or attach device to a power domain), we need to make sure that driver-allocated resources are released immediately after driver's remove() method returns, and not postponed until driver core gets around to releasing resources. To fix that we open a new devres group before calling driver's probe() and explicitly release it when we return from driver's remove().

2021-04-10netfilter: arp_tables: add pre_exit hook for table unregisterFlorian Westphal
Same problem that also existed in iptables/ip(6)tables, when arptable_filter is removed there is no longer a wait period before the table/ruleset is free'd. Unregister the hook in pre_exit, then remove the table in the exit function. This used to work correctly because the old nf_hook_unregister API did unconditional synchronize_net. The per-net hook unregister function uses call_rcu instead.

2021-04-10netfilter: bridge: add pre_exit hooks for ebtable unregistrationFlorian Westphal
Just like ip/ip6/arptables, the hooks have to be removed, then synchronize_rcu() has to be called to make sure no more packets are being processed before the ruleset data is released. Place the hook unregistration in the pre_exit hook, then call the new ebtables pre_exit function from there. Years ago, when first netns support got added for netfilter+ebtables, this used an older (now removed) netfilter hook unregister API, that did a unconditional synchronize_rcu(). Now that all is done with call_rcu, ebtable_{filter,nat,broute} pernet exit handlers may free the ebtable ruleset while packets are still in flight. This can only happens on module removal, not during netns exit. The new function expects the table name, not the table struct. This is because upcoming patch set (targeting -next) will remove all net->xt.{nat,filter,broute}_table instances, this makes it necessary to avoid external references to those member variables. The existing APIs will be converted, so follow the upcoming scheme of passing name + hook type instead.

2021-04-10tty: clarify that not all ttys have a class deviceJohan Hovold
Commit 30004ac9c090 ("tty: add tty_struct->dev pointer to corresponding device instance") added a struct device pointer field to struct tty_struct which was populated with the corresponding tty class device during initialisation. Unfortunately, not all ttys have a class device (e.g. pseudoterminals and serdev) in which case the device pointer will be set to NULL, something which have bit driver authors over the years. In retrospect perhaps this field should never have been added, but let's at least document the current behaviour.

2021-04-10tty: fix return value for unsupported ioctlsJohan Hovold
Drivers should return -ENOTTY ("Inappropriate I/O control operation") when an ioctl isn't supported, while -EINVAL is used for invalid arguments. Fix up the TIOCMGET, TIOCMSET and TIOCGICOUNT helpers which returned -EINVAL when a tty driver did not implement the corresponding operations. Note that the TIOCMGET and TIOCMSET helpers predate git and do not get a corresponding Fixes tag below.
