2021-06-21ipmi: kcs_bmc: Split headers into device and clientAndrew Jeffery7-52/+117
Strengthen the distinction between code that abstracts the implementation of the KCS behaviours (device drivers) and code that exploits KCS behaviours (clients). Neither needs to know about the APIs required by the other, so provide separate headers.

2021-06-21ipmi: kcs_bmc: Turn the driver data-structures inside-outAndrew Jeffery5-67/+110
Make the KCS device drivers responsible for allocating their own memory. Until now the private data for the device driver was allocated internal to the private data for the chardev interface. This coupling required the slightly awkward API of passing through the struct size for the driver private data to the chardev constructor, and then retrieving a pointer to the driver private data from the allocated chardev memory. In addition to being awkward, the arrangement prevents the implementation of alternative userspace interfaces as the device driver private data is not independent. Peel a layer off the onion and turn the data-structures inside out by exploiting container_of() and embedding `struct kcs_device` in the driver private data.

2021-06-21ipmi: kcs_bmc: Split out kcs_bmc_cdev_ipmiAndrew Jeffery4-412/+451
Take steps towards defining a coherent API to separate the KCS device drivers from the userspace interface. Decreasing the coupling will improve the separation of concerns and enable the introduction of alternative userspace interfaces. For now, simply split the chardev logic out to a separate file. The code continues to build into the same module.

2021-05-27char: xillybus: Add driver for XillyUSB (Xillybus variant for USB)Eli Billauer3-0/+2275
The XillyUSB driver is the USB variant for the Xillybus FPGA IP core. Even though it presents a nearly identical API on the FPGA and host, it's almost a complete rewrite of the driver: The framework for exchanging data on a USB bus is fundamentally different from doing the same with a PCIe interface, which leaves very little in common between the existing driver and the new one for XillyUSB.

2021-05-27char: xillybus: Move class-related functions to new xillybus_class.cEli Billauer6-169/+324
This patch is a preparation for adding another related driver, XillyUSB. In order to share some code between the existing Xillybus driver and the one to be added, some functions are moved to xillybus_class.c XILLYBUS_CLASS is added to Kconfig and is common to all drivers in this group. The relation with the existing XILLYBUS symbol is "select" rather than "depends on" XILLYBUS_CLASS, or else "make olddefconfig" will silently turn off XILLYBUS, which is currently enabled in several distributions. XILLYBUS_CLASS doesn't depend on anything else, hence using it with "select" poses no risk for a broken configuration. After the future addition of the XillyUSB module, the tree of symbols will be as follows: XILLYBUS_CLASS --+-- XILLYBUS --+-- XILLYBUS_PCIE | | | +-- XILLYBUS_OF | +-- XILLYUSB XILLYBUS is for drivers based upon memory registers + DMA-based interfaces, and it's combined with XILLYBUS_PCIE and/or XILLYBUS_OF. XILLYUSB is for the USB variant only. Or a more detailed, bottom-up outline: * CONFIG_XILLYBUS_PCIE -> xillybus_pcie.c: Functions related to PCIe. * CONFIG_XILLYBUS_OF -> xillybus_of.c: Functions related to Xillybus as a peripheral on an FPGA / Processor combo chip. * CONFIG_XILLYBUS -> xillybus_core.c: Functions that are common to the two above, mainly access to the peripheral with memory-mapped registers and DMA. * CONFIG_XILLYUSB -> xillyusb.c: The driver for the USB variant, accesses the peripheral through the USB framework. * CONFIG_XILLYBUS_CLASS -> xillybus_class.c: The new module, which contains the class and API parts that would otherwise appear both in xillybus_core.c and xillyusb.c. Contains utility functions for the two latter. And since I'm at it, comments on the module names are added in the Kconfig's help part. The functions are exported with the non-GPL EXPORT_SYMBOL (a matter of taste).

When an IPMI watchdog timer is being stopped in ipmi_close() or ipmi_ioctl(WDIOS_DISABLECARD), the current watchdog action is updated to WDOG_TIMEOUT_NONE and _ipmi_set_timeout(IPMI_SET_TIMEOUT_NO_HB) is called to install this action. The latter function ends up invoking __ipmi_set_timeout() which makes the actual 'Set Watchdog Timer' IPMI request. For IPMI 1.0, this operation results in fully stopping the watchdog timer. For IPMI >= 1.5, function __ipmi_set_timeout() always specifies the "don't stop" flag in the prepared 'Set Watchdog Timer' IPMI request. This causes that the watchdog timer has its action correctly updated to 'none' but the timer continues to run. A problem is that IPMI firmware can then still log an expiration event when the configured timeout is reached, which is unexpected because the watchdog timer was requested to be stopped. The patch fixes this problem by not setting the "don't stop" flag in __ipmi_set_timeout() when the current action is WDOG_TIMEOUT_NONE which results in stopping the watchdog timer. This makes the behaviour for IPMI >= 1.5 consistent with IPMI 1.0. It also matches the logic in __ipmi_heartbeat() which does not allow to reset the watchdog if the current action is WDOG_TIMEOUT_NONE as that would start the timer.

This reverts commit 13bd14a41ce3105d5b1f3cd8b4d1e249d17b6d9b. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. While this is technically correct, it is only fixing ONE of these errors in this function, so the patch is not fully correct. I'll leave this revert and provide a fix for this later that resolves this same "problem" everywhere in this function.

2021-05-13tty: cumulate and document tty_struct::flow* membersJiri Slaby1-4/+4
Group the flow flags under a single struct called flow. The new struct contains 'stopped' and 'tco_stopped' bools which used to be bits in a bitfield. The struct also contains the lock protecting them to potentially share the same cache line. Note that commit c545b66c6922b (tty: Serialize tcflow() with other tty flow control changes) added a padding to the original bitfield. It was for the bitfield to occupy a whole 64b word to avoid interferring stores on Alpha (cannot we evaporate this arch with weird implications to C code yet?). But it doesn't work as expected as the padding (tty_struct::unused) is aligned to a 8B boundary too and occupies some bytes from the next word. So make it reliable by: 1) setting __aligned of the struct -- that aligns the start, and 2) making 'unsigned long unused[0]' as the last member of the struct -- pads the end. This is also the perfect time to start the documentation of tty_struct where all this lives. So we start by documenting what these bools actually serve for. And why we do all the alignment dances. Only the few up-to-date information from the Theodore's comment made it into this new Kerneldoc comment. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: "David S.

2021-05-07drivers/char: remove /dev/kmem for goodDavid Hildenbrand2-241/+0
Patch series "drivers/char: remove /dev/kmem for good". Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and memory ballooning, I started questioning the existence of /dev/kmem. Comparing it with the /proc/kcore implementation, it does not seem to be able to deal with things like a) Pages unmapped from the direct mapping (e.g., to be used by secretmem) -> kern_addr_valid(). virt_addr_valid() is not sufficient. b) Special cases like gart aperture memory that is not to be touched -> mem_pfn_is_ram() Unless I am missing something, it's at least broken in some cases and might fault/crash the machine. Looks like its existence has been questioned before in 2005 and 2010 [1], after ~11 additional years, it might make sense to revive the discussion. CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by mistake?). All distributions disable it: in Ubuntu it has been disabled for more than 10 years, in Debian since 2.6.31, in Fedora at least starting with FC3, in RHEL starting with RHEL4, in SUSE starting from 15sp2, and OpenSUSE has it disabled as well. 1) /dev/kmem was popular for rootkits [2] before it got disabled basically everywhere. Ubuntu documents [3] "There is no modern user of /dev/kmem any more beyond attackers using it to load kernel rootkits.". RHEL documents in a BZ [5] "it served no practical purpose other than to serve as a potential security problem or to enable binary module drivers to access structures/functions they shouldn't be touching" 2) /proc/kcore is a decent interface to have a controlled way to read kernel memory for debugging puposes. (will need some extensions to deal with memory offlining/unplug, memory ballooning, and poisoned pages, though) 3) It might be useful for corner case debugging [1]. KDB/KGDB might be a better fit, especially, to write random memory; harder to shoot yourself into the foot. 4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems to be incompatible with 64bit [1]. For educational purposes, /proc/kcore might be used to monitor value updates -- or older kernels can be used. 5) It's broken on arm64, and therefore, completely disabled there. Looks like it's essentially unused and has been replaced by better suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's just remove it.
