2014-07-04modinfo: fix module parsing with kernel >= 2.6.37David Marchand
display() function returns the length of the value we are displaying + 1. As a consequence, if we have field=value\0field=value\0field=value in the binary, then the second occurence will be skipped as ptr will miss the first character of the following field. Example trying to list aliases from ixgbe.ko on a 3.2 kernel. - In the module we have: alias=pci:v00008086d00001560sv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Asv*sd*bc*sc*i*\0 alias=pci:v00008086d00001557sv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Fsv*sd*bc*sc*i*\0 alias=pci:v00008086d0000154Dsv*sd*bc*sc*i*\0 ... - Using modinfo -F alias ixgbe returns: alias: pci:v00008086d00001560sv*sd*bc*sc*i* alias: pci:v00008086d00001557sv*sd*bc*sc*i* alias: pci:v00008086d0000154Dsv*sd*bc*sc*i* ... This problem appeared with kernel commit "modules: no need to align .modinfo strings" b6472776816af1ed52848c93d26e3edb3b17adab in 2.6.37. Fix this by not trusting display() return value but increment ptr by strlen(ptr) (the same way as depmod.c does).
