2022-05-22random: check for signals after page of pool writesJason A. Donenfeld1-4/+10
get_random_bytes_user() checks for signals after producing a PAGE_SIZE worth of output, just like /dev/zero does. write_pool() is doing basically the same work (actually, slightly more expensive), and so should stop to check for signals in the same way. Let's also name it write_pool_user() to match get_random_bytes_user(), so this won't be misused in the future. Before this patch, massive writes to /dev/urandom would tie up the process for an extremely long time and make it unterminatable. After, it can be successfully interrupted. The following test program can be used to see this works as intended: #include <unistd.h> #include <fcntl.h> #include <signal.h> #include <stdio.h> static unsigned char x[~0U]; static void handle(int) { } int main(int argc, char *argv[]) { pid_t pid = getpid(), child; int fd; signal(SIGUSR1, handle); if (!(child = fork())) { for (;;) kill(pid, SIGUSR1); } fd = open("/dev/urandom", O_WRONLY); pause(); printf("interrupted after writing %zd bytes\n", write(fd, x, sizeof(x))); close(fd); kill(child, SIGTERM); return 0; } Result before: "interrupted after writing 2147479552 bytes" Result after: "interrupted after writing 4096 bytes" Cc: Dominik Brodowski <[email protected]> Signed-off-by: Jason A.

2022-05-22afs: Fix afs_getattr() to refetch file status if callback break occurredDavid Howells1-1/+13
If a callback break occurs (change notification), afs_getattr() needs to issue an FS.FetchStatus RPC operation to update the status of the file being examined by the stat-family of system calls. Fix afs_getattr() to do this if AFS_VNODE_CB_PROMISED has been cleared on a vnode by a callback break. Skip this if AT_STATX_DONT_SYNC is set. This can be tested by appending to a file on one AFS client and then using "stat -L" to examine its length on a machine running kafs. This can also be watched through tracing on the kafs machine. The callback break is seen: kworker/1:1-46 [001] ..... 978.910812: afs_cb_call: c=0000005f YFSCB.CallBack kworker/1:1-46 [001] ...1. 978.910829: afs_cb_break: 100058:23b4c:242d2c2 b=2 s=1 break-cb kworker/1:1-46 [001] ..... 978.911062: afs_call_done: c=0000005f ret=0 ab=0 [0000000082994ead] And then the stat command generated no traffic if unpatched, but with this change a call to fetch the status can be observed: stat-4471 [000] ..... 986.744122: afs_make_fs_call: c=000000ab 100058:023b4c:242d2c2 YFS.FetchStatus stat-4471 [000] ..... 986.745578: afs_call_done: c=000000ab ret=0 ab=0 [0000000087fc8c84] Fixes: 08e0e7c82eea ("[AF_RXRPC]: Make the in-kernel AFS filesystem use AF_RXRPC.")

2022-05-22hwmon: (pmbus) Check PEC support before reading other registersAdam Wujek1-13/+15
Make sure that the support of PEC is determined before the read of other registers. Otherwise the validation of PEC can trigger an error on the read of STATUS_BYTE or STATUS_WORD registers. The problematic scenario is the following. A device with enabled PEC support is up and running and a kernel driver is loaded. Then the driver is unloaded (or device unbound), the HW device is reconfigured externally (e.g. by i2cset) to advertise itself as not supporting PEC. Without the move of the code, at the second load of the driver (or bind) the STATUS_BYTE or STATUS_WORD register is always read with PEC enabled, which is likely to cause a read error resulting with fail of a driver load (or bind).

On 32-bit systems, this results in writes over the end of the bitmap. Fix the problem by using u32 instead of u64 for dimm_mask. This is currently sufficient, and a compile time check to ensure that the number of dimms does not exceed the bit map size is already in place.

This way we allow describing device tree thermal zones for pmbus device drivers with device tree support. This patch achieves this by registering pmbus sensors with thermal subsystem if they are PSC_TEMPERATURE and are providing _input hwmon interface.

Make use of enum chips and use a switch statement in load_attenuators() so that the compiler can tell us if we've failed to cater for a supported chip.

2022-05-22hwmon: (adt7475) Add support for pin configurationChris Packham1-0/+96
The adt7473, adt7475, adt7476 and adt7490 have pins that can be used for different functions. On the adt7473 and adt7475 this is pins 5 and 9. On the adt7476 and adt7490 this is pins 10 and 14. The first pin can either be PWM2(default) or SMBALERT#. The second pin can be TACH4(default), THERM#, SMBALERT# or GPIO. The adt7475 driver has always been able to detect the configuration if it had been done by an earlier boot stage. Add support for configuring the pins based on the hardware description in the device tree.

Add support for the temperatur sensor and the fan controller on the Microchip LAN966x SoC. Apparently, an Analog Bits PVT sensor is used which can measure temperature and process voltages. But only a forumlae for the temperature sensor is known. Additionally, the SoC support a fan tacho input as well as a PWM signal to control the fan.

2022-05-22lib: add generic polynomial calculationMichael Walle4-0/+148
Some temperature and voltage sensors use a polynomial to convert between raw data points and actual temperature or voltage. The polynomial is usually the result of a curve fitting of the diode characteristic. The BT1 PVT hwmon driver already uses such a polynonmial calculation which is rather generic. Move it to lib/ so other drivers can reuse it.

The macros implementing Atari ROM port I/O writes do not cast away their output, unlike similar implementations for other I/O buses. When they are combined using conditional expressions in the definitions of outb() and friends, this triggers sparse warnings like: drivers/net/appletalk/cops.c:382:17: error: incompatible types in conditional expression (different base types): drivers/net/appletalk/cops.c:382:17: unsigned char drivers/net/appletalk/cops.c:382:17: void Fix this by adding casts to "void".

2022-05-21perf session: Fix Intel LBR callstack entries and nr print messageChengdong Li1-5/+21
When generating callstack information from branch_stack(Intel LBR), the actual number of callstack entry should be bigger than the number of branch_stack, for example: branch_stack records: B() -> C() A() -> B() converted callstack records should be: C() B() A() though, the number of callstack equals to the number of branch stack plus 1. This patch fixes above issue in branch_stack__printf().
