Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

lib: reduce the use of module.h wherever possible For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

bug.h: add include of it to various implicit C users With bug.h currently living right in linux/kernel.h there are files that use BUG_ON and friends but are not including the header explicitly. Fix them up so we can remove the presence in kernel.h file. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

lib/string.c: remove duplicated function lib/string.c contains two functions, strnicmp and strncasecmp, which do roughly the same thing, namely compare two strings case-insensitively up to a given bound. They have slightly different implementations, but the only important difference is that strncasecmp doesn't handle len==0 appropriately; it effectively becomes strcasecmp in that case. strnicmp correctly says that two strings are always equal in their first 0 characters. strncasecmp is the POSIX name for this functionality. So rename the non-broken function to the standard name. To minimize the impact on the rest of the kernel (and since both are exported to modules), make strnicmp a wrapper for strncasecmp.

lib: string: Make all calls to strnicmp into calls to strncasecmp The previous patch made strnicmp into a wrapper for strncasecmp. This patch makes all in-tree users of strnicmp call strncasecmp directly, while still making sure that the strnicmp symbol can be used by out-of-tree modules. It should be considered a temporary hack until all in-tree callers have been converted.

[PATCH] x86_64: make string func definition work as intended In include/asm-x86_64/string.h there are such comments: /* Use C out of line version for memcmp */ #define memcmp __builtin_memcmp int memcmp(const void * cs,const void * ct,size_t count); This would mean that if the compiler does not decide to use __builtin_memcmp, it emits a call to memcmp to be satisfied by the C out-of-line version in lib/string.c. What happens is that after preprocessing, in lib/string.i you may find the definition of "__builtin_strcmp". Actually, by accident, in the object you will find the definition of strcmp and such (maybe a trick intended to redirect calls to __builtin_memcmp to the default memcmp when the definition is not expanded); however, this particular case is not a documented feature as far as I can see. Also, the EXPORT_SYMBOL does not work, so it's duplicated in the arch. I simply added some #undef to lib/string.c and removed the (now duplicated) exports in x86-64 and UML/x86_64 subarchs (the second ones are introduced by another patch I just posted for -mm).

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

strcmp: fix overflow and possibly signedness error Doing the strcmp return value as signed char __res = *cs - *ct; is wrong for two reasons. The subtraction can overflow because __res doesn't use a type big enough. Moreover the compared bytes should be interpreted as unsigned char as specified by POSIX. The same problem is fixed in strncmp.

lib: add glibc style strchrnul() variant The strchrnul() variant helpfully returns a the end of the string instead of a NULL if the requested character is not found. This can simplify string parsing code since it doesn't need to expicitly check for a NULL return. If a valid string pointer is passed in, then a valid null terminated string will always come back out. Signed-off-by: Grant Likely <grant.likely@linaro.org>

string: factorize skip_spaces and export it to be generally available On the following sentence: while (*s && isspace(*s)) s++; If *s == 0, isspace() evaluates to ((_ctype[*s] & 0x20) != 0), which evaluates to ((0x08 & 0x20) != 0) which equals to 0 as well. If *s == 1, we depend on isspace() result anyway. In other words, "a char equals zero is never a space", so remove this check. Also, *s != 0 is most common case (non-null string).

lib/string.c: fix strim() semantics for strings that have only blanks Commit 84c95c9acf0 ("string: on strstrip(), first remove leading spaces before running over str") improved the performance of the strim() function. Unfortunately this changed the semantics of strim() and broke my code. Before the patch it was possible to use strim() without using the return value for removing trailing spaces from strings that had either only blanks or only trailing blanks. Now this does not work any longer for strings that *only* have blanks. Before patch: " " -> "" (empty string) After patch: " " -> " " (no change) I think we should remove your patch to restore the old behavior. The description (lib/string.c): * Note that the first trailing whitespace is replaced with a %NUL-terminator => The first trailing whitespace of a string that only has whitespace characters is the first whitespace The patch restores the old strim() semantics.

[PATCH] No arch-specific strpbrk implementations While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

By example: sysfs_streq("a", "b") ==> false sysfs_streq("a", "a") ==> true sysfs_streq("a", "a\n") ==> true sysfs_streq("a\n", "a") ==> true This is intended to simplify parsing of sysfs inputs, letting them avoid the need to manually strip off newlines from inputs.

Add a helper memzero_explicit() (similarly as explicit_bzero() variants) that can be used in such cases where a variable with sensitive data is being cleared out in the end. Other use cases might also be in crypto code.

[PATCH] x86_64: make string func definition work as intended In include/asm-x86_64/string.h there are such comments: /* Use C out of line version for memcmp */ #define memcmp __builtin_memcmp int memcmp(const void * cs,const void * ct,size_t count); This would mean that if the compiler does not decide to use __builtin_memcmp, it emits a call to memcmp to be satisfied by the C out-of-line version in lib/string.c. What happens is that after preprocessing, in lib/string.i you may find the definition of "__builtin_strcmp". Actually, by accident, in the object you will find the definition of strcmp and such (maybe a trick intended to redirect calls to __builtin_memcmp to the default memcmp when the definition is not expanded); however, this particular case is not a documented feature as far as I can see. Also, the EXPORT_SYMBOL does not work, so it's duplicated in the arch. I simply added some #undef to lib/string.c and removed the (now duplicated) exports in x86-64 and UML/x86_64 subarchs (the second ones are introduced by another patch I just posted for -mm).

asmlinkage Make __stack_chk_failed and memcmp visible In LTO symbols implicitely referenced by the compiler need to be visible. Earlier these symbols were visible implicitely from being exported, but we disabled implicit visibility fo EXPORTs when modules are disabled to improve code size. So now these symbols have to be marked visible explicitely. Do this for __stack_chk_fail (with stack protector) and memcmp.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

string: memchr_inv() speed improvements - Generate a 64-bit pattern more efficiently memchr_inv needs to generate a 64-bit pattern filled with a target character. The operation can be done by more efficient way. - Don't call the slow check_bytes() if the memory area is 64-bit aligned memchr_inv compares contiguous 64-bit words with the 64-bit pattern as much as possible. The outside of the region is checked by check_bytes() that scans for each byte. Unfortunately, the first 64-bit word is unexpectedly scanned by check_bytes() even if the memory area is aligned to a 64-bit boundary. Both changes were originally suggested by Eric Dumazet.

Make ARCH_HAS_FAST_MULTIPLIER a real config variable It used to be an ad-hoc hack defined by the x86 version of <asm/bitops.h> that enabled a couple of library routines to know whether an integer multiply is faster than repeated shifts and additions. This just makes it use the real Kconfig system instead, and makes x86 (which was the only architecture that did this) select the option. NOTE! Even for x86, this really is kind of wrong. If we cared, we would probably not enable this for builds optimized for netburst (P4), where shifts-and-adds are generally faster than multiplies. This patch does *not* change that kind of logic, though, it is purely a syntactic change with no code changes. This was triggered by the fact that we have other places that really want to know "do I want to expand multiples by constants by hand or not", particularly the hash generation code.
