getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.Later, we'll add other information to the struct as it becomes
convenient.Signed-off-by: Jeff Layton

try, since the page is in page cache now, ra->mmap_miss is decreased. And

Pull UAPI disintegration fixes from David Howells:
"There are three main parts:(1) I found I needed some more fixups in the wake of testing Arm64
(some asm/unistd.h files had weird guards that caused problems -
mostly in arches for which I don't have a compiler) and some
__KERNEL__ splitting needed to take place in Arm64.(2) I found that c6x was missing some __KERNEL__ guards in its
asm/signal.h. Mark Salter pointed me at a tree with a patch to
remove that file entirely and use the asm-generic variant instead.(3) Lastly, m68k turned out to have a header installation problem due
to it lacking a kvm_para.h file.The conditional installation bits for linux/kvm_para.h, linux/kvm.h
and linux/a.out.h weren't very well specified - and didn't work if
an arch didn't have the asm/ version of that file, but there *was*
an asm-generic/ version.It seems the "ifneq $((wildcard ...),)" for each of those three
headers in include/kernel/Kbuild is invoked twice during header
installation, and the second time it matches on the just installed
asm-generic/kvm_para.h file and thus incorrectly installs
linux/kvm_para.h as well.Most arches actually have an asm/kvm_para.h, so this wasn't
detectable in those."* 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers:

Historically, the top three bytes of personality have been used for
things such as ADDR_NO_RANDOMIZE, which made sense only for specific
architectures.We now however have a flag there that is general no matter the
architecture (UNAME26); generally we have to be careful to preserve the
personality flags across exec().This patch tries to fix all architectures that forcefully overwrite
personality flags during exec() (ppc32 and s390 have been fixed recently
by commits f9783ec862ea ("[S390] Do not clobber personality flags on

asm-generic/unistd.h and a number of asm/unistd.h files have been given
reinclusion guards that allow the guard to be overridden if __SYSCALL is
defined. Unfortunately, these files define __SYSCALL and don't undefine it
when they've finished with it, thus rendering the guard ineffective.The reason for this override is to allow the file to be #included multiple
times with different settings on __SYSCALL for purposes like generating syscall
tables.The following guards are problematic:
arch/arm64/include/asm/unistd.h:#if !defined(__ASM_UNISTD_H) || defined(__SYSCALL)
arch/arm64/include/asm/unistd32.h:#if !defined(__ASM_UNISTD32_H) || defined(__SYSCALL)

include/asm-generic/unistd.h:#if !defined(_ASM_GENERIC_UNISTD_H) || defined(__SYSCALL)On the assumption that the guards' ineffectiveness has passed unnoticed, just

Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.Also, use the generic definition mod_arch_specific where possible.
To this end, I've defined three new config bools:
(*) HAVE_MOD_ARCH_SPECIFIC
Arches define this if they don't want to use the empty generic
mod_arch_specific struct.(*) MODULES_USE_ELF_RELA
Arches define this if their modules can contain RELA records. This causes
the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
defined by the arch rather than have the core emit an error message.(*) MODULES_USE_ELF_REL
Arches define this if their modules can contain REL records. This causes
the Elf_Rel mapping to be emitted and allows apply_relocate() to be
defined by the arch rather than have the core emit an error message.Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.Signed-off-by: David Howells

If the counter overflows during a __delay operation, we will exit the
loop prematurely. For example, calling __delay(0x100) with the counter
at 0xffffff00 gives us a target of 0x0. The unsigned comparison in the
while loop will likely be false on the first iteration (if the counter
is now anything other than 0) and we will return early.This patch fixes the problem by comparing deltas in the loop rather than
absolute values.Cc: Jon Masters

The openrisc implementation of __const_udelay casts the result of a
32-bit multiplication to 64 bits and passes the top 32 bits to __delay.
Since there are no casts on the arguments, this results in a __delay of
zero, regardless of the xloops parameter.This patch fixes the problem by casting xloops to (unsigned long long),
ensuring that the multiplication is not truncated.Cc: Jon Masters

This changes the interfaces in to be a bit more
complicated, but a lot more generic.In particular, it allows us to really do the operations efficiently on
both little-endian and big-endian machines, pretty much regardless of
machine details. For example, if you can rely on a fast population
count instruction on your architecture, this will allow you to make your
optimized file with that.NOTE! The "generic" version in include/asm-generic/word-at-a-time.h is
not truly generic, it actually only works on big-endian. Why? Because
on little-endian the generic algorithms are wasteful, since you can
inevitably do better. The x86 implementation is an example of that.(The only truly non-generic part of the asm-generic implementation is
the "find_zero()" function, and you could make a little-endian version
of it. And if the Kbuild infrastructure allowed us to pick a particular
header file, that would be lovely)The functions are as follows:
- WORD_AT_A_TIME_CONSTANTS: specific constants that the algorithm
uses.- has_zero(): take a word, and determine if it has a zero byte in it.
It gets the word, the pointer to the constant pool, and a pointer to
an intermediate "data" field it can set.This is the "quick-and-dirty" zero tester: it's what is run inside
the hot loops.- "prep_zero_mask()": take the word, the data that has_zero() produced,
and the constant pool, and generate an *exact* mask of which byte had
the first zero. This is run directly *outside* the loop, and allows
the "has_zero()" function to answer the "is there a zero byte"
question without necessarily getting exactly *which* byte is the
first one to contain a zero.If you do multiple byte lookups concurrently (eg "hash_name()", which
looks for both NUL and '/' bytes), after you've done the prep_zero_mask()
phase, the result of those can be or'ed together to get the "either
or" case.- The result from "prep_zero_mask()" can then be fed into "find_zero()"
(to find the byte offset of the first byte that was zero) or into
"zero_bytemask()" (to find the bytemask of the bytes preceding the
zero byte).The existence of zero_bytemask() is optional, and is not necessary
for the normal string routines. But dentry name hashing needs it, so
if you enable DENTRY_WORD_AT_A_TIME you need to expose it.This changes the generic strncpy_from_user() function and the dentry
hashing functions to use these modified word-at-a-time interfaces. This
gets us back to the optimized state of the x86 strncpy that we lost in
the previous commit when moving over to the generic version.Signed-off-by: Linus Torvalds
