strict_strto* is not strict enough

2009-01-06T23:59:12+00:00

It decodes "\n" as 0, which is bad, because stray echo into backlight will turn your backlight off, etc... Signed-off-by: Pavel Machek Cc: Yi Yang Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Make %p print '(null)' for NULL pointers

2009-01-03T19:46:17+00:00

Before, when we only ever printed out the pointer value itself, a NULL pointer would never cause issues and might as well be printed out as just its numeric value. However, with the extended %p formats, especially %pR, we might validly want to print out resources for debugging. And sometimes they don't even exist, and the resource pointer is just NULL. Print it out as such, rather than oopsing. This is a more generic version of a patch done by Trent Piepho (catching all %p cases rather than just %pR, and using "(null)" instead of "[NULL]" to match glibc).

aoe: remove private mac address format function

2008-11-25T08:40:37+00:00

Add %pm to omit the colons when printing a mac address. Signed-off-by: Harvey Harrison Signed-off-by: David S. Miller

printk: ipv4 address digits printed in reverse order

2008-11-04T01:09:55+00:00

put_dec_trunc prints the digits in reverse order and is reversed inside number(). Continue using put_dec_trunc, but reverse each quad in ip4_addr_string. [Noticed by Julius Volz] Signed-off-by: Harvey Harrison Signed-off-by: David S. Miller

printk: add %I4, %I6, %i4, %i6 format specifiers

2008-10-29T19:49:58+00:00

For use in printing IPv4, or IPv6 addresses in the usual way: %i4 and %I4 are currently equivalent and print the address in dot-separated decimal x.x.x.x %I6 prints 16-bit network order hex with colon separators: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx %i6 omits the colons.

printk: add %p6 format specifier for IPv6 addresses

2008-10-28T23:04:44+00:00

Takes a pointer to a IPv6 address and formats it in the usual colon-separated hex format: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx Each 16 bit word is printed in network-endian byteorder. %#p6 is also supported and will omit the colons. %p6 is a replacement for NIP6_FMT and NIP6() %#p6 is a replacement for NIP6_SEQFMT and NIP6() Note that NIP6() took a struct in6_addr whereas this takes a pointer to a struct in6_addr.

printk: add %pM format specifier for MAC addresses

2008-10-28T00:06:15+00:00

Add format specifiers for printing out six colon-separated bytes: MAC addresses (%pM): xx:xx:xx:xx:xx:xx %#pM is also supported and omits the colon separators. Signed-off-by: Harvey Harrison Signed-off-by: David S. Miller

Implement %pR to print struct resource content

Add a %pR option to the kernel vsnprintf that prints the range of addresses inside a struct resource passed by pointer. Signed-off-by: Linus Torvalds Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Linus Torvalds

lib: remove defining macros for strict_strto??

2008-10-16T21:58:08+00:00

Open-code them rather than using defining macros. The function bodies are now next to their kerneldoc comments as a bonus. Add casts to the signed cases as they call into the unsigned versions. Avoids the sparse warnings: lib/vsprintf.c:249:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:249:1: expected unsigned long *res lib/vsprintf.c:249:1: got long *res lib/vsprintf.c:249:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:249:1: expected unsigned long *res lib/vsprintf.c:249:1: got long *res lib/vsprintf.c:251:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:251:1: expected unsigned long long *res lib/vsprintf.c:251:1: got long long *res lib/vsprintf.c:251:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:251:1: expected unsigned long long *res lib/vsprintf.c:251:1: got long long *res Signed-off-by: Harvey Harrison Signed-off-by: Linus Torvalds
