2018-12-22tracing: Make function ‘ftrace_exports’ staticMathieu Malaterre1-1/+1
In commit 478409dd683d ("tracing: Add hook to function tracing for other subsystems to use"), a new function ‘ftrace_exports’ was added. Since this function can be made static, make it so. Silence the following warning triggered using W=1: kernel/trace/trace.c:2451:6: warning: no previous prototype for ‘ftrace_exports’ [-Wmissing-prototypes] Link: http://lkml.kernel.org/r/20180516193012.25390-1-malat@debian.org Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2018-12-22tracing: Simplify printf'ing in seq_print_symRasmus Villemoes1-4/+3
trace_seq_printf(..., "%s", ...) can be done with trace_seq_puts() instead, avoiding printf overhead. In the second instance, the string we're copying was just created from an snprintf() to a stack buffer, so we might as well do that printf directly. This naturally leads to moving the declaration of the str buffer inside the CONFIG_KALLSYMS guard, which in turn will make gcc inline the function for !CONFIG_KALLSYMS (it only has a single caller, but the huge stack frame seems to make gcc not inline it for CONFIG_KALLSYMS).

2018-12-22tracing: Avoid -Wformat-nonliteral warningRasmus Villemoes1-5/+4
Building with -Wformat-nonliteral, gcc complains kernel/trace/trace_output.c: In function ‘seq_print_sym’: kernel/trace/trace_output.c:356:3: warning: format not a string literal, argument types not checked [-Wformat-nonliteral] trace_seq_printf(s, fmt, name); But seq_print_sym only has a single caller which passes "%s" as fmt, so we might as well just use that directly. That also paves the way for further cleanups that will actually make that format string go away entirely.

2018-12-22tracing: Use hist trigger's var_ref array to destroy var_refsTom Zanussi1-5/+19
Since every var ref for a trigger has an entry in the var_ref[] array, use that to destroy the var_refs, instead of piecemeal via the field expressions. This allows us to avoid having to keep and treat differently separate lists for the action-related references, which future patches will remove.

2018-12-22tracing: Use var_refs[] for hist trigger reference checkingTom Zanussi1-57/+11
Since all the variable reference hist_fields are collected into hist_data->var_refs[] array, there's no need to go through all the fields looking for them, or in separate arrays like synth_var_refs[], which will be going away soon anyway.

2018-12-22tracing: Fix ftrace_graph_get_ret_stack() to use task and not currentSteven Rostedt (VMware)1-2/+2
The function ftrace_graph_get_ret_stack() takes a task struct descriptor but uses current as the task to perform the operations on. In pretty much all cases the task decriptor is the same as current, so this wasn't an issue. But there is a case in the ARM architecture that passes in a task that is not current, and expects a result from that task, and this code breaks it.

2018-12-22seq_buf: Use size_t for len in seq_buf_puts()Michael Ellerman1-1/+1
Jann Horn points out that we're using unsigned int for len in seq_buf_puts(), which could potentially overflow if we're passed a UINT_MAX sized string. The rest of the code already uses size_t, so we should also use that in seq_buf_puts() to avoid any issues.

2018-12-22seq_buf: Make seq_buf_puts() null-terminate the bufferMichael Ellerman1-1/+5
Currently seq_buf_puts() will happily create a non null-terminated string for you in the buffer. This is particularly dangerous if the buffer is on the stack. For example: char buf[8]; char secret = "secret"; struct seq_buf s; seq_buf_init(&s, buf, sizeof(buf)); seq_buf_puts(&s, "foo"); printk("Message is %s\n", buf); Can result in: Message is fooªªªªªsecret We could require all users to memset() their buffer to zero before use. But that seems likely to be forgotten and lead to bugs. Instead we can change seq_buf_puts() to always leave the buffer in a null-terminated state. The only downside is that this makes the buffer 1 character smaller for seq_buf_puts(), but that seems like a good trade off.

The PM816 module is a versatile PMIC with many diverse functions integrated, including, a watchdog. This watchdog is subcomponent of the PON (Power On) peripheral, in the same way as pwrkey/resin buttons. It works with two timers (2-stages), the first one generates an IRQ to the main SoC (APQ8016/MSM8916), the second one performs the reset. This driver expects the following device hierarchy: [pm8916]->[pm8916-pon]->[pm8916-wdt] It uses the pm8916 regmap to access PM8916 registers.

2018-12-22powerpc/83xx: handle machine check caused by watchdog timerChristophe Leroy4-4/+26
When the watchdog timer is set in interrupt mode, it causes a machine check when it times out. The purpose of this mode is to ease debugging, not to crash the kernel and reboot the machine. This patch implements a special handling for that, in order to not crash the kernel if the watchdog times out while in interrupt or within the idle task.

2018-12-22xfs: reallocate realtime summary cache on growfsOmar Sandoval1-8/+36
At mount time, we allocate m_rsum_cache with the number of realtime bitmap blocks. However, xfs_growfs_rt() can increase the number of realtime bitmap blocks. Using the cache after this happens may access out of the bounds of the cache. Fix it by reallocating the cache in this case.

2018-12-22powerpc/fsl_pci: simplify fsl_pci_dma_set_maskChristoph Hellwig1-5/+1
swiotlb will only bounce buffer when the effective dma address for the device is smaller than the actual DMA range. Instead of flipping between the swiotlb and nommu ops for FSL SOCs that have the second outbound window just don't set the bus dma_mask in this case.

2018-12-22hwmon: (lm80) fix a missing check of bus read in lm80 probeKangjie Lu1-2/+9
In lm80_probe(), if lm80_read_value() fails, it returns a negative error number which is stored to data->fan[f_min] and will be further used. We should avoid using the data if the read fails. The fix checks if lm80_read_value() fails, and if so, returns with the error number. Signed-off-by: Kangjie Lu <kjlu@umn.edu> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
