2013-08-21kernel: crashlog: Avoid out-of-bounds writenbd
vsnprintf returns the number of chars that would have been written, not the actual number of chars written. This can lead to crashlog_buf->len being too big which in turn can lead to get_maxlen() returning negative numbers. The length argument of kmsg_dump_get_buffer will be casted to a size_t which makes a negative input a big positive number allowing kmsg_dump_get_buffer to write out of bounds. Fix this by using vscnprintf which returns the actually written number of chars.

This is crashing the kernel in crashlog_init_fs(), until fixed, disable it for SPARC too. Signed-off-by: Florian Fainelli <florian@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@34213 3c298f89-4303-0410-b956-a3cf2f4a3e73
2012-08-12generic: use __meminit annotation for crashlog_init_memblockjuhosg
Fixes this section mismatch warning: WARNING: vmlinux.o(.meminit.text+0xb14): Section mismatch in reference from the function memblock_insert_region() to the function .init.text:crashlog_init_memblock() The function __meminit memblock_insert_region() references a function __init crashlog_init_memblock(). If crashlog_init_memblock is only used by memblock_insert_region then annotate crashlog_init_memblock with a matching annotation. Also, remove the __init annotations from 'include/linux/crashlog.h' git-svn-id: svn://svn.openwrt.org/openwrt/trunk@33137 3c298f89-4303-0410-b956-a3cf2f4a3e73
