2023-10-30scripts/kernel-doc: Fix the regex for matching -Werror flagYujie Liu1-1/+1
Swarup reported a "make htmldocs" warning: Variable length lookbehind is experimental in regex; marked by <-- HERE in m/(?<=^|\s)-Werror(?=$|\s) <-- HERE / at ./scripts/kernel-doc line 188. Akira managed to reproduce it by perl v5.34.0. On second thought, it is not necessary to have the complicated "lookahead and lookbehind" things, and the regex can be simplified. Generally, the kernel-doc warnings should be considered as errors only when "-Werror" flag is set in KCFLAGS, but not when "-Werror=<diagnostic-type>" is set, which means there needs to be a space or start of string before "-Werror", and a space or end of string after "-Werror". The following cases have been tested to work as expected: * kernel-doc warnings are considered as errors: $ KCFLAGS="-Werror" make W=1 $ KCFLAGS="-Wcomment -Werror" make W=1 $ KCFLAGS="-Werror -Wundef" make W=1 $ KCFLAGS="-Wcomment -Werror -Wundef" make W=1 * kernel-doc warnings remain as warnings: $ KCFLAGS="-Werror=return-type" make W=1 $ KCFLAGS="-Wcomment -Werror=return-type" make W=1 $ KCFLAGS="-Werror=return-type -Wundef" make W=1 $ KCFLAGS="-Wcomment -Werror=return-type -Wundef" make W=1 The "Variable length lookbehind is experimental in regex" warning is also resolved by this patch.

2023-10-30iommufd/selftest: Fix page-size check in iommufd_test_dirty()Joao Martins1-2/+4
iommufd_test_dirty()/IOMMU_TEST_OP_DIRTY sets the dirty bits in the mock domain implementation that the userspace side validates against what it obtains via the UAPI. However in introducing iommufd_test_dirty() it forgot to validate page_size being 0 leading to two possible divide-by-zero problems: one at the beginning when calculating @max and while calculating the IOVA in the XArray PFN tracking list. While at it, validate the length to require non-zero value as well, as we can't be allocating a 0-sized bitmap.

2023-10-30fbdev: stifb: Make the STI next font pointer a 32-bit signed offsetHelge Deller1-1/+1
The pointer to the next STI font is actually a signed 32-bit offset. With this change the 64-bit kernel will correctly subract the (signed 32-bit) offset instead of adding a (unsigned 32-bit) offset. It has no effect on 32-bit kernels. This fixes the stifb driver with a 64-bit kernel on qemu. Signed-off-by: Helge Deller <[email protected]> Cc: [email protected]

2023-10-30parisc: Add nop instructions after TLB insertsJohn David Anglin1-29/+52
An excerpt from the PA8800 ERS states: * The PA8800 violates the seven instruction pipeline rule when performing TLB inserts or PxTLBE instructions with the PSW C bit on. The instruction will take effect by the 12th instruction after the insert or purge. I believe we have a problem with handling TLB misses. We don't fill the pipeline following TLB inserts. As a result, we likely fault again after returning from the interruption. The above statement indicates that we need at least seven instructions after the insert on pre PA8800 processors and we need 12 instructions on PA8800/PA8900 processors. Here we add macros and code to provide the required number instructions after a TLB insert.

2023-10-30parisc: simplify smp_prepare_boot_cpu()Russell King (Oracle)1-7/+1
smp_prepare_boot_cpu() reads the cpuid of the first CPU, printing a message to state which processor booted, and setting it online and present. This cpuid is retrieved from per_cpu(cpu_data, 0).cpuid, which is initialised in arch/parisc/kernel/processor.c:processor_probe() thusly: p = &per_cpu(cpu_data, cpuid); ... p->cpuid = cpuid; /* save CPU id */ Consequently, the cpuid retrieved seems to be guaranteed to also be zero, meaning that the message printed in this boils down to: pr_info("SMP: bootstrap CPU ID is 0\n"); Moreover, since kernel/cpu.c::boot_cpu_init() already sets CPU 0 to be present and online, there is no need to do this again in smp_prepare_boot_cpu().

2023-10-28seq_buf: Introduce DECLARE_SEQ_BUF and seq_buf_str()Kees Cook3-17/+19
Solve two ergonomic issues with struct seq_buf; 1) Too much boilerplate is required to initialize: struct seq_buf s; char buf[32]; seq_buf_init(s, buf, sizeof(buf)); Instead, we can build this directly on the stack. Provide DECLARE_SEQ_BUF() macro to do this: DECLARE_SEQ_BUF(s, 32); 2) %NUL termination is fragile and requires 2 steps to get a valid C String (and is a layering violation exposing the "internals" of seq_buf): seq_buf_terminate(s); do_something(s->buffer); Instead, we can just return s->buffer directly after terminating it in the refactored seq_buf_terminate(), now known as seq_buf_str(): do_something(seq_buf_str(s)); Link: https://lore.kernel.org/linux-trace-kernel/[email protected] Link: https://lore.kernel.org/linux-trace-kernel/[email protected]/ Cc: Yosry Ahmed <[email protected]> Cc: "Matthew Wilcox (Oracle)" <[email protected]> Cc: Christoph Hellwig <[email protected]> Cc: Justin Stitt <[email protected]> Cc: Kent Overstreet <[email protected]> Cc: Petr Mladek <[email protected]> Cc: Andy Shevchenko <[email protected]> Cc: Rasmus Villemoes <[email protected]> Cc: Sergey Senozhatsky <[email protected]> Cc: Masami Hiramatsu <[email protected]> Cc: Greg Kroah-Hartman <[email protected]> Cc: Arnd Bergmann <[email protected]> Cc: Jonathan Corbet <[email protected]> Cc: Yun Zhou <[email protected]> Cc: Jacob Keller <[email protected]> Cc: Zhen Lei <[email protected]> Signed-off-by: Kees Cook <[email protected]> Signed-off-by: Steven Rostedt (Google) <[email protected]>
