treewide: Convert macro and uses of section(foo) to section("foo")

2020-10-25T21:51:49Z

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.pl Signed-off-by: Joe Perches Reviewed-by: Nick Desaulniers Reviewed-by: Miguel Ojeda Signed-off-by: Linus Torvalds

printk: move dictionary keys to dev_printk_info

2020-09-22T09:27:48Z

Dictionaries are only used for SUBSYSTEM and DEVICE properties. The current implementation stores the property names each time they are used. This requires more space than otherwise necessary. Also, because the dictionary entries are currently considered optional, it cannot be relied upon that they are always available, even if the writer wanted to store them. These issues will increase should new dictionary properties be introduced. Rather than storing the subsystem and device properties in the dict ring, introduce a struct dev_printk_info with separate fields to store only the property values. Embed this struct within the struct printk_info to provide guaranteed availability.

kernel.h: Move oops_in_progress to printk.h

The oops_in_progress is defined in printk.c, so it's logical to move oops_in_progress to printk.h. Signed-off-by: Andy Shevchenko Acked-by: Sergey Senozhatsky Signed-off-by: Petr Mladek Link: https://lore.kernel.org/r/20200911170202.8565-1-andriy.shevchenko@linux.intel.com

printk: Make linux/printk.h self-contained

2020-07-27T08:46:24Z

As it stands if you include printk.h by itself it will fail to compile because it requires definitions from ratelimit.h. However, simply including ratelimit.h from printk.h does not work due to inclusion loops involving sched.h and kernel.h. This patch solves this by moving bits from ratelimit.h into a new header file which can then be included by printk.h without any worries about header loops. The build bot then revealed some intriguing failures arising out of this patch. On s390 there is an inclusion loop with asm/bug.h and linux/kernel.h that triggers a compile failure, because kernel.h will cause asm-generic/bug.h to be included before s390's own asm/bug.h has finished processing. This has been fixed by not including kernel.h in arch/s390/include/asm/bug.h.

dynamic_debug: add an option to enable dynamic debug for modules only

2020-06-08T18:05:56Z

Instead of enabling dynamic debug globally with CONFIG_DYNAMIC_DEBUG, CONFIG_DYNAMIC_DEBUG_CORE will only enable core function of dynamic debug. With the DYNAMIC_DEBUG_MODULE defined for any modules, dynamic debug will be tied to them. This is useful for people who only want to enable dynamic debug for kernel modules without worrying about kernel image size and memory consumption is increasing too much.

sysctl: pass kernel pointers to ->proc_handler

2020-04-27T06:07:40Z

Instead of having all the sysctl handlers deal with user pointers, which is rather hairy in terms of the BPF interaction, copy the input to and from userspace in common code. This also means that the strings are always NUL-terminated by the common code, making the API a little bit safer. As most handler just pass through the data to one of the common handlers a lot of the changes are mechnical. Signed-off-by: Christoph Hellwig Acked-by: Andrey Ignatov Signed-off-by: Al Viro
